I. Overview of ZFQ-1 explosion - proof fire - resistance breathing valve :
ZFQ-1 all-weather explosion-proof fire-resistance breathing valve integrates flame arrester and breathing valve, and its novel structure is the first in China. It is a new type of safety equipment necessary for petrochemical storage tanks. Its biggest advantages are good fire resistance and breathing performance, light weight and easy maintenance. This product is suitable for oils with a storage point below 28 ℃ and Class B oils with a flash point below 60 ℃, such as gasoline, stupid, paraffin, kerosene, light diesel oil, engine oil, crude oil, and other properties The same chemical product storage tank is used, it works normally in the temperature environment of -35 ℃ -60 ℃.

Performance and characteristics of ZFQ-1 explosion-proof fire -resistance breathing valve :
The shell is made of cast steel and aluminum alloy with good corrosion resistance;
The corrugated fire barrier is made of stainless steel, which has good fire resistance and corrosion resistance;
Simple structure, easy maintenance, safe and convenient;

Third, ZFQ-1 explosion-proof fire resistance breathing valve maintenance and maintenance:
In order to use the breathing valve safely, the corrugated fire barrier layer should be removed and cleaned regularly within 3-6 months to ensure that each hole in the fire barrier layer is unblocked to prevent blockage and ensure safe and normal use.
Regularly check whether the positive and negative valve discs are ventilated flexibly and whether the contact surfaces of the guide rods and valve discs are damaged. Replace them immediately if damaged.
When inspecting, maintaining and reinstalling, it is necessary to ensure that the joint surfaces in the valve are closely matched and the valve disc is flexible to lift.
When the new valve is activated, the anti-vibration between the discs should be removed before installation, otherwise the breathing valve will fail.
