I. Overview of GFQ-2 all - weather breathing valve :
GFQ-2 breathing valve is used on oil and liquid tanks to exclude the positive pressure and negative pressure gas in the tank to make the liquid in and out of the tank convenient. For example, there is a certain obstacle to the liquid in and out of the tank without the breathing valve on the tank. Variations and vibrations of the tank are likely to occur. The product has a reasonable design, simple structure and easy use; it is an essential product for storage tanks and is indispensable.

Performance and characteristics of GFQ-2 all-weather breathing valve:
1. The new all-weather breathing valve housing is made of cast iron, cast steel and aluminum alloy, and has good corrosion resistance;
2.The valve disc is made of PTFE material, which is resistant to low temperature and has good antifreeze performance.
3. Simple structure, easy maintenance, safe and convenient;
4. The performance of the new all-weather breathing valve fully meets the requirements of the Ministry of Petroleum Industry Standard SY7511-87.

Application range of GFQ-2 all-weather breathing valve:
The new all-weather breathing valve is suitable for storing Class A oil products with a flash point below 28 ℃ and Class B oil products with a flash point below 60 ℃, such as gasoline, stupid, paraben, kerosene, light diesel, engine oil, crude oil And chemical product storage tanks of the same nature. It can be used with new type corrugated flame arrester.

Fourth, GFQ-2 all - weather breathing valve instructions:
The breathing valve is installed on the top of the storage tank, which is to solve the positive pressure and negative pressure gas in the tank, so that the liquid in and out of the tank is not hindered. When the external liquid enters the tank, a large amount of gas is called out (called positive pressure). For example, when the liquid in the tank is exported to the outside, the inside of the tank must be sucked into the tank from outside air (called negative pressure). If the breathing valve is automatically closed when it stops working, the liquid in the tank will not leak to the outside, so that the quality of the liquid in the tank is favorably guaranteed.

Five, GFQ-2 all-weather breathing valve maintenance and maintenance:
In order to use the breathing valve safely, check the guide rod and valve disc for flexibility before use.
The valve should be checked regularly (within 6 months) whether the positive and negative valve discs on the vent are flexible and the contact surface of the valve disc is damaged. If it is damaged, it should be repaired immediately. & # 8226; After the maintenance is over, everything is normal and can be reused.
