Hydraulic shutter - valve for discharging liquid or gas

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 be in such a situation in your own apartment. Agree, it is uncomfortable to live in a room where there is a constant stench of sewage. And, what is most interesting, absolutely everyone can encounter this problem, especially when designing a new house. When constructing such buildings in order to prevent the occurrence of terrible sewage smells, a special shutter is installed for the discharge of liquid or gas, also called hydraulic. What is it like and how is it arranged? The answers to all these questions will be found in the article presented.

Device

The design of such a device as a shutter for the discharge of liquid or gas, assumes the presence of the following parts:

• Pipes that connects the device tank to the sewer.
• Masking flange.
• Pipes 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 part of the tank).

Additionally, the liquid or gas discharge valve may be provided with a connection for draining the washing machine, which also prevents the possible penetration of unpleasant odors into the interior of the room. In addition, in the case of frequent condensation, which arises from the difference in temperature, this shutter is additionally equipped with a special retaining washer.

Principle of operation

Hydraulic butterfly valve according to its algorithm of action is a very primitive device, because its design simply does not have any moving elements. Its work is based on the difference in pressure in the same pipeline due to the use of a special insert of a tortuous shape. This very bend just does not make it possible to penetrate the gases back into the sink. However, it is worthwhile to focus on the correspondence of the angle of inclination and placement of this part of the pipe. If its level after carrying out of a horizontal strip will have any deviations, it is possible, soon unpleasant smells emanating from the central pipeline of the water drain will get into 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 application of this device is widely used for the installation of shower cabins, bathtubs, toilet bowls and kitchen sinks.

In some cases, the use of this part makes it easier to install and install the process and connect the pipe without the use of a bolt and other cutting tools.

Thus, all these types of closures are not only a convenient adapter, but also an important device that serves as a hydraulic valve.
