Probably each of us knows how unpleasant the smell coming from the sewer. Often, such "surprises" appear on the street with an open hatch or a faulty pipeline. However, it is much more unpleasant to find yourself in such a situation in your own apartment. Agree, it’s uncomfortable to live in a room where there is a constant stink of sewage. Moreover, what is most interesting, absolutely everyone can face such a problem, especially when designing a new house. When constructing such buildings, in order to prevent the appearance of terrible sewer odors, a special shutter is installed to release liquid or gas, which is also called hydraulic. What is it and how is it structured? You will find the answers to all these questions in the article.
Device
The design of a device such as a shutter for the release of liquid or gas, requires the following parts:
- The pipe that connects the device’s tank to the sewer.
- Masking flange.
- The pipe that connects this shutter to the sewer and washbasin.
- A few nuts and, as a rule, no more than three rubber gaskets (these devices are an integral part of the tank).
Additionally, the shutter for the discharge of liquid or gas can be equipped with a fitting for connecting the drain of the washing machine, which also prevents the possible penetration of unpleasant odors into the room. In addition, in the case of frequent formation of condensate, which occurs due to temperature differences, this valve is additionally equipped with a special retaining washer.
Principle of operation
The hydraulic wafer gate, by its algorithm of action, is a very primitive device, since there are simply no moving elements in its design. His work is based on the pressure difference in the same pipeline through the use of a special sinuous insert. This very bend just does not allow the gases to penetrate back into the sink. However, it is worth focusing on the correspondence of the angle of inclination and placement of this part of the pipe. If its level after the horizontal strip will have any deviations, it is possible that unpleasant odors coming from the central sewage pipeline will soon enter the room.
Where is it installed?
If you think that the shutter for discharging liquid or gas is mounted only in sinks and washing machines, you are deeply mistaken. The use of this device is widespread when installing showers, bathtubs, toilets and kitchen sinks.
Moreover, in some cases, the use of this part allows you to facilitate the installation process and to connect the pipe without the use of grinders and other cutting tools.
Thus, all these types of valves are not only a convenient adapter, but also an important device that acts as a hydraulic valve.
