What is StopCock?

In plumbing terminology, the stop is a type of valve used to complete the flow of gas or water into the system. Sometimes they are called the main water valves, StopCocks control the flow of water or gas into the plumbing system of the building from the main power line. In areas operated by the local usefulness provider, this valve is placed outside the building, often in the same general place as the meter. Depending on the service provider, this valve may be locked to prevent unauthorized use and handling. In most modern systems, another StopCock can be installed inside the building to allow the water or gas supply to be quickly disconnected in an emergency. The plug is connected to a small handle that can turn to an open or closed position. In most cases, this handle is a small, smooth, rectangular projection that requires a special tool called StopCock key, crejedl lever effect required to turn on or off the valve. When turning in the direction of hOdin hands with a handle created by a handle run parallel to the main line and the service is on. When turning counter -clockwise, the handle line is perpendicular to the main line and the service is disconnected.

Due to the nature of plumbing systems, local building regulations require in many areas the installation of a secondary stem hill inside the building. This secondary StopCock is a protective device for the building owner in case of damage to the plumbing system. These internal stopwatch often have a different handle design than the outdoor stopwatch used by the service provider that makes it easier to use without using a special key or other tools.

While StopCocks do not require great maintenance, long periods of use in the on or off position can result in a plug and unusable when the valve requires. To avoid this problem, buildings are encouragedni, aby pravidelně testovali funkci sekundárních stop. Chcete -li provést tento test, jednoduše otočte rukojeť ventilu a dočasně připojte nebo odpojíte službu. Pokud se rukojeť ventilu netočí snadno, může být vyžadována údržba nebo výměna ventilu.
