Description

The utility model relates to a cap sewer siphon closure according to claim 1 of the utility model formula.

The cap drain siphon closure acts as a barrier to gas and odor to sewer gases from the sewer pipe. Due to the amount of water (so-called hydraulic shutter water) retained in the cap of the siphon drain valve or the certain level of water in the cap of the siphon drain valve, the rise of gases or odors from the pipeline is prevented.

A disadvantage of the still known cap siphon drainage gates is that after the water of the hydraulic lock in the cap siphon drainage valve has evaporated over time, the gases from the pipeline can escape, which can lead to gas contamination or even poisoning.

The utility model is based on the task of proposing a cap drainage siphon closure, which even without the presence of hydraulic shutter water prevents gases from escaping from the pipeline.

This problem is solved by means of a cap sewer siphon valve according to claim 1 of the utility model.

First of all, the problem is solved by means of a cap sewer siphon valve for a sewer pipe including a substantially airtight membrane, the membrane being made and positioned so that the membrane in a closed normal state essentially seals the water opening for the cap sewer siphon valve and under the pressure of the flowing wastewater is translated into an open release state in which the membrane is at least partially absorbed a hole for the flow of waste water awaits.

An essential point of the utility model is that, in the normal state, the membrane essentially seals the opening for the water flow of the cap of the sewer siphon valve, while it temporarily (partially) releases the opening for the flow of water with flowing wastewater. The advantage of this is that no odors can escape from the sewer pipe, even when there is no more water from the hydraulic seal in the cap of the sewer siphon valve (more). In addition, the evaporation of the hydraulic shutter water is greatly reduced. In addition, the reverse flow of wastewater from the sewer pipe is substantially prevented.

In one embodiment, the membrane has a substantially truncated sphere shape and is positioned between the substantially cylindrical inner hollow body and the cylindrical outer hollow body located substantially coaxially to the inner hollow body such that the membrane in a closed normal state hermetically closes the substantially circular washer-shaped opening for the flow of water between the inner hollow body and the outer hollow body. The advantage of this is that no gas can flow from the sewer pipe to the cap drain siphon valve. In addition, the evaporation of water in the direction of the sewer pipe is prevented. In addition, this ensures that no wastewater can flow back from the sewer pipe to the cap sewer siphon closure. Thus, the cap of the sewer siphon valve and, thus, possibly present in the cap of the sewer siphon valve of the hydraulic shutter is protected from contamination by sewage from the sewer pipe.

In yet another embodiment, the membrane has a substantially truncated cone shape and is located in a substantially cylindrical inner hollow body of the cap of the siphon drainage cap so that the membrane in a closed normal state substantially seals the opening for the flow of wastewater of the internal hollow body. Thus, due to the membrane, the evaporation of water in the direction of flow of wastewater is prevented. Even if the water of the hydraulic shutter has evaporated, the membrane ensures that no odors can come from the sewer pipe. In addition, it is also prevented that odors that are generated in the cap of the siphon drain valve due to the presence of water from the hydraulic lock can escape from the cap of the siphon drain valve.

The outer hollow body may have a protrusion located essentially in the center for centering and connecting the outer hollow body to the inner hollow body. Thus, the centering of both hollow bodies relative to each other is greatly facilitated. In addition, the displacement of both hollow bodies relative to each other is also substantially prevented.

The membrane can be fixed on the external hollow body, especially on the protrusion of the external hollow body. Thus, you can simply remove and clean the internal hollow body.

The membrane can be fixed to the internal hollow body. Thus, you can simply remove and clean the external hollow body.

Fig.6 is an exploded view of the cap of the sewer siphon closure according to Fig.5.

In the following description, the same reference characters will be used for the same and the same acting parts.

Figure 1 shows a cross-sectional view of one embodiment of a cap sewer siphon valve 1 according to a utility model. Figure 2 shows a disassembled view of the cap of the sewer siphon valve 1 according to figure 1. The cap sewer siphon closure 1 includes an inner hollow body 10, which is in the form of a substantially hollow cylinder. The shape of the inner hollow body 10 corresponds to a straight circular cylinder, which is open in the upper and lower directions.

The cap sewer siphon closure 1 also includes an external hollow body 20, which also has the form of a substantially hollow cylinder. The shape of the outer hollow body 20 corresponds to a straight circular cylinder, which is open in the upper direction and closed in the lower direction. The inner hollow body 10 has a smaller diameter than the outer hollow body 20. The inner hollow body 10 is located in the center of the outer hollow body 20.

The outer hollow body 20 has in its center an awl-shaped protrusion 25 that protrudes above the upper edge of the cylindrical wall 22 of the outer hollow body 20. Through this protrusion 25, a connection is established between the inner hollow body 10 and the outer hollow body 20 and the inner hollow body 10 is fixed.

The cap sewer siphon closure 1 serves to prevent the escape of gases or odors from the sewer pipe. The upper end of the internal hollow body 10 is connected to the influx of wastewater. The wastewater inflow is, for example, an effluent or an industrial effluent. The upper end of the outer hollow body 20 is hydraulically connected to a sewer pipe (not shown). A sewer pipe is, for example, part of a municipal sewer network or municipal sewer.

The waste water in the embodiment shown in FIG. 1 flows in the inner hollow body 10 and then flows into or through the hole 30 for the wastewater flow between the inner hollow body 10 and the outer hollow body 20. From this hole 30 for the wastewater flow, water then flows to sewer or sewage. The hole 30 for the wastewater duct has a substantially circular shape in cross section perpendicular to the outer wall 13 of the inner hollow body 10 or the outer hollow body 20.

In the cap of the sewer siphon valve, 1 part of the wastewater is constantly held in place as the water 50 of the hydraulic valve. The shutter water 50 prevents air communication between the inner hollow body 10 and the wastewater opening 30 between the inner hollow body 10 and the outer hollow body 20. This prevents odors or gases from the sewer pipe from entering the inner hollow body 10 and, thereby, get into the flow of wastewater.

A membrane 40 is located between the inner hollow body 10 and the outer hollow body 20 at the upper end of the outer hollow body 20. The membrane 40 in FIG. 1 is in a closed normal state. In the closed normal state, the membrane 40 closes the annular flow hole 30 in the cross section between the inner hollow body 10 and the outer hollow body 20. In this way, gases or odors can escape from the sewage water drain or sewage network, even when cap siphon drain valve 1 (more) there is no water 50 hydraulic valve. In addition, the evaporation of the water 50 of the hydraulic shutter is significantly reduced.

Even if the gate valve water 50 has evaporated, the membrane 40 prevents gases or air from entering the sewer pipe into the inner hollow body 10 and thereby leaving the sewer pipe. Therefore, even when the cap of the sewer siphon closure cap 1 is completely dry, it is ensured that no odors or gases can escape from the sewer line.

The membrane is substantially airtight. Preferably, the membrane 40 consists of an elastic material, such as, for example, rubber or soft plastics.

The membrane 40 is fixed on the outside of the inner hollow body 10. The membrane 40 can, for example, be glued and / or fixed by clamps. Other fixing methods are possible.

The membrane 40 in the closed normal state abuts against the inner side of the outer hollow body 20 and thereby closes the flow hole 30 for wastewater. The membrane in the normal state is located between the inner hollow body 10 and the outer hollow body 20 at an angle of about 10 ° -15 ° (to the horizontal).

That is, the membrane 40 touches the wall 22 of the outer hollow body 20 at a higher position than the outer wall 13 of the inner hollow body 10.

When water drains, the flowing water displaces the membrane 40, as a result of which the membrane 40 is separated from the inner side of the outer hollow body 20 and, thereby, at least partially releases the flow hole 30 (the so-called open unlocking state). Thus, under the pressure of the wastewater, the flow hole 30 partially or substantially completely releases. The higher the pressure of the flowing wastewater, the stronger the membrane 40 is pushed aside and the greater the part of the flow hole 30 is released.

As soon as the wastewater that pushes the membrane 30 no longer drains, the membrane 40 returns to its closed normal state, in which the membrane 40 seals the flow hole 30 substantially hermetically. The membrane 40 is designed so that the membrane 40 again takes its original shape, so that it, after the end of the flow of water, returns to its normal state.

The membrane 40 is located near the upper edge of the outer hollow body 20.

The inner hollow body 10, as well as the membrane 40 can be easily removed from the outer hollow body 10, for example, in order to clean the inner hollow body 10.

The membrane may be permanently integrated, but may also be replaceable.

Figure 3 shows a cross-sectional view of another embodiment of a cap sewer siphon valve 1 according to a utility model. The membrane 40 in FIG. 3 is located in the inner hollow body 10. In the closed normal state, the membrane 40 closes the flow hole 30 inside the inner hollow body 10 essentially sealed. The membrane 40 is located near the upper end of the inner hollow body 10. The outer hollow body 20 has in its center an awl-shaped protrusion 25. The protrusion 25 extends above the height of the wall 22 of the outer hollow body 20. The membrane in FIG. 3 is fixed to the protrusion 25. In the closed normal state, it adjacent to the inner walls of the inner hollow body 10 and, thereby, closes the flow hole 30 inside the inner hollow body 10. The flow hole 30 is between the protrusion 25 of the outer hollow body 20 and the inner wall 12 of the inner hollow body 10. In the pope a river cross-section perpendicular to the inner wall 12 of the inner hollow body 10, the flow opening 30 has the shape of a substantially circular washer.

When the wastewater flows in the inner hollow body 10, the wastewater displaces the membrane 40, as a result of which the membrane 40 is separated from the inner wall 12 of the inner hollow body 10. Due to this, the flow hole 30 inside the inner hollow body 10 is at least partially released. As soon as no more water drains and, therefore, no pressure is exerted on the membrane 40, the membrane 40 returns to its original shape and, as a result, again substantially seals the flow opening 30.

The membrane 40 is located at an angle of about −5 ° from the protrusion 25 of the outer hollow body 20 to the inner wall 12 of the inner hollow body 10. That is, the membrane 40 touches the protrusion 25 at a higher position than the inner wall 12 of the inner hollow body 10.

The membrane 40 has the shape of a substantially truncated cone in FIGS. 1 and 2. By the shape of a truncated cone is meant the lateral surface of the truncated cone. In a plan view, the membrane 40 in FIGS. 1 and 2 is in the form of a substantially circular ring.

3 and 4, the membrane 40 also has the shape of a truncated cone, that is, the shape of the membrane 40 corresponds to the outer surface of the truncated cone. In the view of the membrane 40 from above, the membrane 40 in FIGS. 3 and 4 is in the form of a substantially circular washer.

Other forms of the membrane 40 are possible, especially other forms of the membrane 40 in the form of a truncated cone or a lateral surface of the truncated cone.

It is also possible that the internal field body 10 and / or the external hollow body 20 are elliptical in cross section. The shape of the membrane 40 is thus adapted to the shape of the inner hollow body 10 or the outer hollow body 20, so that the membrane 40 in the normal state essentially seals the flow opening 30.

Figure 5 shows a cross-sectional view of another embodiment of a cap sewer siphon valve 1 according to a utility model. Figure 6 shows a disassembled view of the cap of the sewer siphon valve 1 according to figure 5. While in FIGS. 1-4, the cylindrical outer hollow body 20 was open in the upper direction, the cylindrical outer body 20 in FIG. 5 and 6 is open in the lower direction. The inner hollow body 10 in FIG. 5 and FIG. 6, as in the embodiments shown in FIGS. 1-4, is open in both the upper and lower directions. The cap sewer siphon valve 1 in FIG. 5 or FIG. 6 is very similar to the cap sewer siphon valve according to FIGS. 1 and 2, which is placed on the head, i.e. rotated 180 °.

The membrane 40 is located between the inner hollow body 10 and the outer hollow body 20. It is fixed to the inner wall or wall 22 of the outer hollow body 20.

A lip seal 70 is located at the lower end of the inner hollow body 10, which substantially completely covers the lower part of the inner hollow body 10. This facilitates sealing of the inner hollow body 10 with respect to a sewer pipe (not shown). Other types of sealing are possible.

In FIG. 6, the inner hollow body 10 has a handle 38 on its upper side, which is located essentially centrally along its upper side. Through this handle 38, the inner hollow body 10 can be easily raised. A handle 38 divides the open upper side of the inner hollow body 10 into two substantially semicircular openings 35, 35 '. The handle 38 in FIG. 5 is parallel to the cross section, therefore, in FIG. 5, none of these two holes 35, 35 ′ are visible.

The shape of the membrane 40 corresponds to the shape of the outer surface of the truncated cone.
