GFQ - type 2 stainless steel valves used in oil and liquid tank breathing, to rule out positive pressure and negative pressure gas tank, the tank liquid in and out of convenience. Don't put the respiration valve tank such as tank liquid in and out of the obstacles to a certain extent, the likely variant and vibration of tank, the product design is reasonable, simple structure, easy to use;Is necessary for storage tank, are indispensable. GFQ - type 2 stainless steel breathing valve performance and features: New all-weather breathing valve housing cast iron, cast steel and aluminum alloy, good corrosion resistance. With four fluorine valve plate material, low temperature resistant, antifreeze performance is good; Simple structure, easy maintenance, safe and convenient; New GFQ - type 2 stainless steel breathing valve performance fully comply with the regulations of ministry of petroleum industry standard SY7511-87. GFQ - type 2 stainless steel breathing valve of the scope of application: GFQ - type 2 stainless steel breathing valve is suitable for storage flash point less than 28 ℃ a oil and flash point is lower than 60 ℃ b product, such as gasoline, stupid, stupid, kerosene, light diesel oil, engine oil, crude oil and oil products and chemical products, all of the same character storage tank.Can be used with new corrugated flame arrester. GFQ instructions - 2 stainless steel breathing valve: Breathing valve installed on the top of the tank, is to solve tank positive pressure, negative pressure of gas, make the tank of liquid in and out not impeded, when external tank liquid input from time to tome a lot of gas to call (called a positive pressure).Such as tank liquid tank must be the output of the outward from the outside air into the tank (negative pressure).If stop working when breathing valve automatically shut down will not leak the gas tank out, make the tank of liquid quality got favorable guarantee. GFQ - 2 stainless steel breathing valve maintenance: In order to use security breather valve, before use, first check the guide rod and valve plate is flexible. This valve (6 months) regularly check whether the vent valve plate of positive and negative is flexible, valve plate surface is damaged, if there is any damage shall be immediately overhaul.After the maintenance, all normal can be used again.
