Double nozzles breather valve flame arrester
Double nozzles breather valve flame arrester Compact structure, large ventilation, small leakage, corrosion resistance, good sealing performance and so on.
According to the provisions of the national standard "Code for Design Fire Protection of Petrochemical Enterprises" (GB50160-90), "the fixed roof tank of class A and B liquids shall be equipped with flame arrester and breathing valve". It can be seen that the breathing valve and the flame arrester are indispensable safety facilities for the storage tank.Double nozzles breather valve flame arrester It can not only maintain the pressure balance of the tank,flame arrester ensure that the tank is destroyed during overpressure or vacuum, but also reduce the volatilization and loss of the medium in the tank. The valve is installed on the top of the nitrogen sealed tank,fire arrestor which is a safe and energy-saving product to maintain the pressure balance of the storage tank and reduce the volatilization of the medium. It is often used with the flame arrester.
