Product Description

GFQ-1 all-weather breathing valve
Used for oil and liquid tanks, to remove the positive pressure and negative pressure gas in the tank, so that the liquid in the tank is convenient to enter and exit. If the tank is not equipped with breathing valve, the liquid in the tank has certain obstacles, it is likely to appear tank deformation and vibration,GFQ-2 all-weather breathing valve design is reasonable, simple structure, easy to use; It is an essential product of the storage tank.
Gfq-ii type all-weather breathing valve performance and characteristics
New all-weather breathing valve shell selection of stainless steel, cast steel and aluminum alloy, good corrosion resistance;
The valve disc is made of tetrafluoroidal material, which has good low temperature resistance and antifreeze performance;
Simple structure, easy maintenance, safe and convenient;
The performance of the new all-weather breathing valve fully conforms to the provisions of the Ministry of Petroleum Industry standard SY7511-87.
Gfq-ii type all-weather breathing valve application range
The new all-weather breathing valve is suitable for storing Class A oil with flash point below 28 ° C and Class B oil with flash point below 60 ° C, such as gasoline, benzine, methyl benzine, kerosene, light diesel, oil, crude oil and other oil products and chemical product storage tanks with the same nature. The all-weather breather valve can be used with ZGB ripple flame arrester.
GFQ-1 all-weather breathing valve, also known as all-weather breathing valve, with desiccant breathing valve instructions
The all-weather breathing valve is installed on the top of the storage tank, which is to solve the positive pressure and negative pressure of the gas in the tank, so that the liquid in the tank is not hindered, and when the external liquid is input into the tank, a large amount of gas is exhaled (called positive pressure). If the liquid in the tank is exported, the tank must be sucked into the tank from the outside air (called negative pressure). If the breathing valve is automatically closed when it stops working, it will not leak the liquid gas in the tank outwards, so that the liquid quality in the tank has been favorable protection.
GFQ-1 all-weather breathing valve, also known as all-weather breathing valve, with desiccant breathing valve maintenance and maintenance
In order to use the all-weather breathing valve safely, check whether the guide rod and valve disc are flexible before use. The all-weather breathing valve should regularly (within 6 months) check whether the positive and negative valve disc of the vent is flexible, and whether the contact surface of the valve disc is damaged. If there is damage, it should be repaired immediately. After the overhaul is completed, everything can be used again in normal condition.
