How does a gas check valve work?

人气: Editor-in-chief: Shanxi Fire Equipment Popularity: Time: 2018-05-25 [Large Middle Small]
    The gas check valve is used in the combination distribution system. When a fire occurs in the protective area and the corresponding drive nitrogen gas cylinder is opened, the gas is started through the selection valve cylinder, the selection valve is opened, and the gas check line is continued through the gas check valve to open the corresponding Mixed gas storage bottle, and other bypass valve and corresponding mixed gas storage bottle should not be opened to achieve the function of combined distribution.
