This hydraulic fracturing siphon creates an air barrier between the boiler and the outlet hose, preventing germs from entering the water heating device. Sewage drain: types, selection criteria, features Sewage inlet funnel

The Austrian company HL (Hutterer & Lechner KG) is a world leader in the field of production sewerage equipment(drains, funnels, storm drains, storm water inlets, valves, gates, flanges, siphons, outlets, adapters, cuffs, pipes, etc. HL sewerage equipment has been produced in Austria and Germany for more than 100 years.

We offer a wide range of HL sewerage equipment allowing you to choose the one sewer drain, roof funnel, sewer seal, check valve or siphon that you need for a specific project, and do not tailor the project to specific equipment.

Our organization offers the following HL sewerage equipment:

HL funnels for internal storm drains can be used on all flat roofs with any hydro- and vapor barrier materials, with “pies” of any thickness and filling. HL funnels with both vertical (outlet sizes DN 40, 50, 70, 100, 125 and 150) and horizontal outlets (DN 70, 100); with compression flange made of of stainless steel(for any waterproofing materials) or with a polymer-bitumen sheet for welding.

To improve the quality of roof repairs or when using old storm drains when reconstructing buildings, we offer repair funnels HL with outlet DN 70, 100, 125, 150 for steel or smooth walls cast iron pipe. We can also offer roof drains using the “water pump” principle with a PE outlet pipe for welding.

For balconies and terraces we offer HL funnels and drains with a swivel joint and an outlet pipe rotation angle from 0° to 90°. For our climate zone The most suitable are HL funnels with built-in electric heating (a self-regulating cable that changes its heat output depending on the air temperature).

Advantages of HL roof drains:

Power supply from 220V network (no need for a step-down transformer);
- electrical cable located inside the funnel body made of PP (there is no danger of breakdown through water drained from the roof);
- durability of the electrical cable (no contact with the environment);
- With outside the cable is shielded with thermal insulation (all the heat goes to heating the inner surface of the funnel);
- self-regulating electrical cable (no need to install remote thermostats);
- operating temperature from -50 to +100°C;
- PP material is not afraid of ultraviolet radiation, and its acid resistance is superior to cast iron and stainless steel;
- simple installation (no thermal compensators required);
- durability.

In any public establishments, such a device must be installed, in accordance with plumbing standards. It is also advisable to install it in apartments.

How does a burst siphon work?

The standard type of siphon connects the drain hole to the sewer outlet pipe. It protects against penetration unpleasant odors using a water seal system. A siphon with a jet break has a gap between the outlet and the receiving pipe. Thanks to this, a direct connection between the outlet point of drain liquids and the main part of the water seal system is eliminated. First, the water enters a special funnel, and then into the pipe. This design leaves no chance for pathogenic microbes, which is why it is recommended to install a siphon with a flow break. You can buy it at any time in our plumbing store in Moscow.

Types of siphons

We offer the following types of siphons with a stream break:

• Siphon with a receiving funnel with an outlet of 32 mm;
• Siphon with a receiving funnel with an outlet of 40 mm;
• Siphon with an oval receiving funnel and a universal type outlet pipe;
• Siphon with an oval receiving funnel and a horizontal outlet pipe.

Features of using a siphon with a jet break

The water jet gap is 20-30 mm. This gap is enough to interrupt the path of microbes. Also this distance will not give annoying sounds falling water. This important condition, allowing you to maintain hygiene standards in in public places. The system can be designed so that drains from several washbasins converge into one funnel. Then the sewerage device will be used rationally. We offer only high-quality siphon with a stream break, the price of which is very reasonable.

The sewer drain is special variety drain funnel, built directly into the floor or any other horizontal surface. Such a funnel works both as a drain and as a siphon, ensuring effective drainage of wastewater and the absence of a specific sewage odor in the serviced area.

A typical sewer drain consists of the following structural elements:

• Front panel , built into a plane, into a specially equipped cavity.
• Intake funnel located under the panel. Using a funnel, you can adjust the installation height of the drain by installing the product in a slab with a thickness of 50 to 200 millimeters.
• Base bodies with overflow , forming a hydraulic valve, or with a dry valve. Moreover, at the base there can be either one or several branches, with the help of which the drain is connected to several sewer branches at once or cuts into an existing pipeline.

• Cups and racks . The cup insert retains large inclusions. The grille traps hair and filters runoff.

• Seals and fasteners , sealing interface units constituent elements housings. Using seals, you can secure the drain outlet in the socket of the sewer pipe, fix the funnel in the body and seal the gap under the front panel.

The drain point in the shower and the drain are arranged in a similar way. storm sewer, and a funnel in the production room. The functional purpose of the ladder does not affect the structural design.

Types of drains for sewerage

The classification of sewer drains can be built according to the following schemes:

• By design features

In this case, two groups are distinguished in the assortment: horizontal and vertical. The funnel of the horizontal drain is oriented vertically, and the drain fitting of the base body is oriented horizontally. In a vertical drain, the funnel and drain fitting are oriented along a common axis (vertical).

Horizontal drains are compact, while vertical drain points provide maximum throughput. For example, at least 3.5 liters of liquid per second can be passed through a vertical drain for sewage systems in buildings 100b.

• By shutter type

In this case, the assortment is divided into “dry” and “wet” groups. Dry ladders are arranged according to the scheme check valve– the pressure of the waste “opens” the membrane or float partition, which “slams shut” after the water goes into the pipeline. Wet drains are designed according to a siphon with a hydraulic seal - an S-shaped channel is built between the funnel and the drain fitting.

Moreover, dry drains are considered more reliable than their counterparts with a hydraulic seal. After all, the water in the S-shaped channel can dry out or simply flow into sewer pipe when overpressure, provoked by failures in fan boner. As a result, owners of a “wet” drain run the risk of encountering not the most pleasant odors, the source of which is sewage.

• By type of material used in the manufacture of the ladder

In this case, the assortment of drains can be divided into three groups, namely: plastic, metal and mixed.

Plastic sewer drain made from structural polymers - polyvinyl chloride, polyethylene or polypropylene. The main advantage of such ladders is inertia construction material. Plastic does not rust or oxidize when in contact with concentrated acids. The main disadvantages are low mechanical and temperature strength. Plastic will not withstand a sharp impact, abrasive load and wastewater temperatures above 50-70 degrees Celsius.

Steel and cast iron sewer drains made from stainless steel or malleable cast iron. The main advantage of such ladders is their high strength. This product will withstand both impact and high temperature and corrosion. The main disadvantage is the high price.

Composite drains from a mixed group made from metals and polymers. Moreover, only the upper (visible) part of the ladder is made of durable and expensive metal, while the base body and other “internal” elements are made of cheap plastic. Such products will last longer than polymer drains and will cost less than their metal counterparts.

Review of popular models

Popular models of flat-mounted flush points include the following products:

• Polish ladder 15 B110 RM , the body of which is made of polymer, and the front panel and funnel are made of stainless steel. The height of such a ladder can be adjusted by moving the funnel, which is fixed using a flange seal. The diameter of the drain fitting is 110 millimeters. The dimensions of the lattice front panel are 150x150 millimeters. Price – 14 euros.

Natural moisture retention on the surface is a feature flat roofs. It accumulates due to rain and melting snow. To prevent flooding of upper floors and staircases, they are used special devices. A receiving funnel for storm drainage on the roof drains water from the roof in a timely manner, equally successfully protecting institutions, apartment and private buildings, and industrial facilities.

Purpose of funnels for storm drainage

Water inlet for flat roofs

The main task of the products is to remove liquid from the roof. To do this, a drainage mechanism is installed on the roof, combining several funnels. They are mounted in a certain sequence, covering the entire surface. Through them, water flows through pipes into a sewer, ravine or ditch, beyond the territory of the facility.

Funnels must meet certain standards:

• durable, waterproof contact with the roofing waterproofing system;
• sufficient length of the pipe for connection to the riser in the attic or in the ceiling room;
• a filtration system that protects the pipe from blockages.

Together, these parameters will ensure rapid removal of excess liquid from the roof.

Types and design of funnels

Leaf catcher for roof drains

There are many types storm funnels, combined into 2 basic categories:

• flat models with grilles;
• bell-type modifications.

In the first case, installation is carried out on monolithic roofs without a sand layer. The gratings are made in the form of cells, squares, ovals, etc. All storm water flows from above, so the grate is at or slightly below roof level. Protection against debris is provided by a galvanized mesh, umbrella or internal cone.

The bell structure includes the funnel itself, the inner umbrella, and the cap (glass and lid). The edges are equipped with special teeth that clamp the roofing material tightly adjacent to the surface. There are ribs inside that open a small gap for water to drain. As a result, leaves, paper and other debris do not fall into the pipe, preventing blockages.

Production materials

Bell funnel for storm drainage

When choosing a material, facility owners and specialists are guided by its ability to withstand moisture. Because of this preference for a long time favored cast iron and galvanized steel. Today they are also widely used, but are largely being replaced by plastic, which has already proven its effectiveness.

• Cast iron monolithic models. A common version, adapted to tightly clamp the roll surface. It forms a waterproofing carpet, quickly removing excess moisture. Cast iron is also in demand due to decorative properties– bell structures created from it look representative.
• Steel modifications. A reliable option, used both in lattice models and in hoods. Funnels are made from semi-boiler, asphalted, galvanized iron, which guarantees a long service life and protection against corrosion. Performance properties are practically not inferior to cast iron, while steel costs much less.
• Plastic option. It is characterized by increased practicality and ease of installation. Such structures better withstand the effects of moisture, temperature and other environmental factors. The service life is not limited, and the price is much lower, which is especially important when completing industrial facilities.

The choice of material is determined by the characteristics of the object, including its area, appearance, aesthetic requirements.

Features of installing funnels on the roof

The installation of structures, their number and the interval between funnels depends on the characteristics of the object: area, configuration, rain volume and other parameters. In practice, the distance between the 2 elements is about 25 meters, which is enough for timely drainage. A smaller amount leads to clogging of the funnels with subsequent accumulation of liquid on a flat surface.

All components are connected to drainpipes, in case of overload is formed backup system. It is activated during spring melting of snow, heavy rain or during prolonged rains. In this case, it is important that the receiving part does not become clogged.

Installation is carried out in several stages:

1. The internal element is inserted into a special hole on the roof. The fastener should not be rigid.
2. The outer part is inserted from above, passing it through the roofing carpet and insulation. A seal ring is placed between the 2 elements.
3. The cap apron is installed on a roofing felt lining and an additional waterproofing layer.
4. The funnel is inserted into the bowl roof covering, which is fixed with a ring and fastening components.
5. The process completes the installation of the protective grille.

Success is determined by competent work planning and qualified specialists.

Siphon with jet break required for installation in public places in accordance with SanPiN 2.4.1.2660-10. Prevents the entry of E. coli from the drain into the sink due to the non-contact connection to the sink.

The main purpose of the siphon is to limit odors from the sewerage system so that they do not enter the premises where they are located. plumbing fixtures. This is a water castle.

Here is an excerpt from the Sanitary and Epidemiological Requirements for the Design, Content and Organization of Work in Preschool Organizations Sanitary and Epidemiological Rules and Standards SanPiN 2.4.1.2660-10

14.9. At the point where the production baths are connected to the sewer, there must be an air gap of at least 20 mm from the top of the receiving funnel, which is installed above the siphon devices.

Why do you need a siphon with a jet break?

By sanitary standards The sewage system (toilets and washbasins) should not come into contact with the production area associated with the preparation of products for industrial purposes (for example, canteens of all levels from kindergarten to the restaurant). This can be achieved in two ways.The first is the construction of separate systems, with separate outlets into the well.Second installation siphon with jet break.

Simply put, this is done to prevent any microbes from getting through the pipe into the sink from the sewer. The presence of a rupture in the stream does not relieve one from the obligation to install a siphon elbow (hydraulic seal).

Now siphons with a jet break are produced by both domestic and foreign manufacturers.
