There are three kinds of civil gas valves that everyone should know.
1. The residential pipeline gas valve
This kind of pipeline valve refers to the main valve of the pipeline in the residence unit, a kind of shut-off valve used both in the high-rise residential and in the stairwell of the buildings. It plays a role in controlling people’s residential consumption of the gas, prohibited opening or closing at will, and prohibited opening it again when an accident occurred to make it closed. This kind of pipeline gas shut-off valve acts as an important guardian in ensuring the overall safety of residential gas use.
2.Ball valve in front of the meters
On the pipeline that connects to the user's residences, a ball valve should be installed in front of the gas meters. For users who will not use gas for a long period, the valve in front of the meter should be closed. When other gas facilities behind the valve have broken down, the valve in front of the meter should be closed to ensure no gas leakage will be caused. If the user installs a solenoid valve and an gas alarm, then in the event of a gas leak, the alarm will sound and the solenoid valve will simply cut off the gas supply. In such an emergency, the manual ball valve is used as a mechanical device to ensure the safety when other safeguards fail.
3. The valve in front of the stove
The valve in front of the stove is a control valve between the gas pipeline and the stove, named the self-closing safety valve. This valve is driven by the mechanical structure, which can realize the automatic closing for overpressure, automatic closing when the lack of pressure, and automatic closing when the flow is too large, adding a strong safety guarantee for the use of gas stoves. Usually, there will be a ball valve in its front end so the gas could be cut off manually as well.
