When using the internal flame arrester components of the QZF-89 antifreeze flame arrester, the contact area between the small flame and the channel wall should be expanded as much as possible to enhance heat transfer and lower the flame temperature below the ignition point, thereby preventing flame propagation.

 

The QZF-89 antifreeze flame arrester is in accordance with the GB standard "Fire Protection Design Code for Petrochemical Enterprises" (GB50160-92), which stipulates that fixed top tanks for Class A and B liquids should be equipped with flame arresters and breathing valves. Breathing valves and flame arresters are indispensable safety facilities for storage tanks. It can not only maintain the pressure balance of the storage tank, ensuring that the tank is not damaged during overpressure or vacuum, but also reduce the volatilization and loss of the medium inside the tank.

 

The antifreeze (flame retardant) breathing valve, also known as the "German style breathing valve," has the characteristics of high ventilation, low leakage, and corrosion resistance. This type of breathing valve has anti freezing performance and is suitable for cold areas. There are single * exhalation and inhalation channels, and the positive pressure valve disc and negative pressure valve disc are not connected to each other.

 

Application and characteristics of QZF-89 antifreeze flame arrester

 

The use of QZF-89 antifreeze flame arrester

 

The QZF-89 antifreeze flame arrester is a ventilation device installed on a fixed roof tank, which reduces oil evaporation loss, controls tank pressure, and prevents external flames from entering.

 

The characteristics of QZF-89 antifreeze flame arrester

 

The QZF-89 antifreeze flame arrester has the characteristics of high ventilation, low leakage, corrosion resistance, etc., and has an electrostatic grounding wire to maintain an equal potential between the valve and the tank body. This valve has anti freezing performance and is suitable for cold regions.
