QZF-89 Atmospheric pressure vacuum relief valve with flame arrestor
Model is designed to vent to atmosphere to prouect your tank from damage created by over - pressure or excessive vacuum .The flame arrestor performs as an extinguishing barrier ,which absorbs and dispels heat ,reduces fire temperature and the oxygen level to stop the fire through layers of metal ribbons shaoed with crimped corrugations.
With the improvement of technologies of valve, valve areas continuously expanding, the corresponding valves standard is more and more indispensable. Valve industry has entered a period of innovation, product categories require not only new replace, internal management of enterprises also need to be based on industry standards for further reform.
Explosion-proof fire breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work, equipped with fire retardant explosion-proof function.
Fire breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulation, etc.
The valve adopts polytetrafluoroethylene material, has the advantages of low temperature resistant, anti frost.
The electrostaticprotection device is provided with a respiratory valve, the valve and the tank to keep the
same potential moment.
