The household gas emergency shutoff valve is a safety device for home gas pipeline. It is combined with the household gas alarm to form an emergency gas cutting system. When the gas leakage reaches a certain concentration, the linkage device, as an alarm, cuts off the gas in 0.5 seconds, thus avoiding the explosion and poisoning. The gas emergency shutoff valve we produce has three national patents, and it is safe and reliable. Range of application: 1. Connect to the household combustible gas leak detector. When the instrument detects the leaking of the combustible gas, the valve is closed automatically and quickly, the supply of gas is cut off, and the occurrence of the malignant events is stopped in time. 2. The source of gas is cut off when the gas pipeline system is overhauled and troubleshooting.
