Proper installation and maintenance of explosion-proof flame arrestor breathing valves ensure steady progress in production.

According to Shangmei Online, the explosion-proof flame arrestor breathing valve is a common type of valve that maintains the pressure balance of storage tanks and reduces medium volatilization. This explosion-proof breathing valve combines the functions of a flame arrestor and a breathing valve, making it a new type of safety device essential for petrochemical storage tanks. It is widely used in the domestic market and serves as a 'stabilizer' for the safe application of petrochemical storage tanks.
Shanghai Wuyue Pump and Valve Group, as a company deeply rooted in this industry for many years, excels in technology, service, and after-sales support. The company's explosion-proof flame arrestor breathing valve maintains a high market share in the domestic market, which is closely related to its manufacturing technology and processes.
The principle of this product is to use the weight of the positive and negative pressure valve disc to control the positive pressure of exhaust and the negative pressure of intake in the storage tank. When medium is drawn out of the tank, the gas space in the upper part of the tank decreases, reaching the operating negative pressure of the breathing valve. At this point, the external atmospheric pressure will push open the negative pressure valve disc of the breathing valve, allowing external gas to enter the tank, preventing the internal pressure from continuing to drop and balancing the pressure between the inside and outside of the tank to protect the safety device of the storage tank. When the pressure of the medium inside the tank is within the control operating pressure range of the explosion-proof flame arrestor breathing valve, the breathing valve does not operate, maintaining the airtightness of the oil tank. When medium is replenished into the tank, causing the pressure in the upper gas space to rise and reach the operating positive pressure of the breathing valve, the pressure valve is pushed open, allowing gas to escape from the breathing valve outlet, preventing the internal pressure from continuing to increase.
