Explosion-proof fire breathing valve performance characteristics and maintenance
Explosion-proof fire breathing valve overview: ZFQ-1 all-weather explosion-proof fire breathing valve set flame arrester and breathing valve as one of its novel structure for the domestic initiative. It is a necessary new type of petrochemical storage tank safety equipment, its greatest advantage is fire breathing resistance, light weight, easy maintenance. This product is suitable for storing Class A oil products with internal point lower than 28 ℃ and Group B oil products with flash point lower than 60 ℃, such as gasoline, stupid, stupid, kerosene, light diesel oil, engine oil and crude oil The same chemical tank used, it is -35 ℃ -60 ℃ temperature environment in normal work. Explosion-proof fire breathing valve performance and features: Cast steel and aluminum alloy shell selection, corrosion resistance; Corrugated fire-resistant layer of stainless steel, fire retardant performance, good corrosion resistance; Simple structure, easy maintenance, safe and convenient ; Explosion-proof fire breathing valve maintenance and care: In order to use the safety valve, should be within 3-6 months regularly remove the ripple fire, clean, to ensure that each hole on the fire barrier smooth, to prevent blockage, Ensure safe and normal use. Periodically check ventilation positive and negative valve disc movements are flexible, guide rod and disc contact sealing surface for damage, if damaged should be immediately replaced. In the inspection and maintenance to re-install, should ensure that the valve surface with a tight fit, the valve lift flexible. When the new valve is activated, the shock-proof material between the valve discs should be removed before installation, otherwise the breathing valve will fail.
