ZFQ-1 all-weather Fire breathing valve explosion-proof

Name: weather-proof Fire breathing valve related products Model: ZFQ-1 weather-proof Fire breathing valve diameter: DN50-250mm media: Oil Tel: 021-51097581 Yang Chen Product Description Overview: ZFQ-1 all-weather-proof barrier Fire breathing valve. The product set with a flame arrester breathing valve as a whole, its novel structure for domestic initiative. It is a new petrochemical tank necessary safety equipment, its biggest advantage is good Fire breathing performance, light weight, easy maintenance. Oil and the nature of the product is suitable for storage in the point below 28 ℃ CPI oil and flash point below 60 ℃ of B oil, such as gasoline, benzene, toluene, kerosene, light diesel oil, oil, crude oil and other chemical products use the same storage tank, it works fine at -35 ℃ -60 ℃ ambient temperature of. Performance and features: steel and aluminum case selection, good corrosion resistance; fire resistant layer of corrugated stainless steel, good fire resistance, good corrosion resistance; simple structure, easy maintenance, safe and convenient; Maintenance: To breathing valve using security, fire resistant layer should be removed periodically corrugated in 3-6 months, clean, ensure the smooth flow of each hole on the fire resistant layer, to prevent clogging, ensure the safety of normal use. Periodic inspection through the atmosphere positive and negative valve disc movement is flexible, the guide rod and the valve disc contacts the sealing surface for damage, if damaged should be immediately replaced. In the inspection, maintenance, re-installation, should ensure that the joint surface of each valve tight fit, flexible disc lift. When the new valve is enabled, clear the shock front should be installed between the valve disc material, or breathing valve failure. The main technical parameters: A-level positive airway pressure 355Pa (36 mm water column) vacuum 295Pa (30 mm water column) B-level positive airway pressure 980Pa (100 mm water column) vacuum 295Pa (30 mm water column) Grade C positive pressure 1765Pa (180 mm water column) negative pressure 295Pa (30 mm water column) Parts Material: Body Material Carbon Steel WCB, 304,316 stainless steel, aluminum positive pressure valve plate material stainless steel 304, aluminum vacuum valve plate material stainless steel 304, PTFE PTFE Ambient temperature ℃ -30 ~ 60 Operating pressure Pa -295 ~ 98000 -30mmH2O ~ + 10000mmH2O
