Role purpose: Breathing valve is a safe and energy-saving product to maintain the pressure balance of storage tank and reduce the volatilization of medium. Breathing valve makes full use of the bearing capacity of storage tank itself to reduce the discharge of medium. Its principle is to use the weight of positive and negative pressure valve plate to control the positive exhaust pressure and negative suction pressure of storage tank. When the pressure of the medium in the tank is within the range of the control operating pressure of the breathing valve, the breathing valve does not work to maintain the tightness of the tank; When the tank to add medium, so that the tank upper gas space pressure, to achieve the breathing valve operation positive pressure, pressure valve is opened, gas from the breathing valve exhalation outlet escape, so that the pressure in the tank no longer continue to increase; Beyond can take out medium, make the tank top gas pressure drop of the space, achieve the respiration valve operating pressure, open the atmosphere outside the tank will be breathing valve open the suction valve plate, the gas into the tank, the tank pressure is no longer continue to fall, let the tank and tank pressure balance, to protect the safety of the tank.
Features and performance: New pipe flame arrester material: cast iron, cast steel, stainless steel, aluminum alloy, good corrosion resistance. The disc and seal ring are made of stainless steel tetrafluoroethylene. Low temperature resistance, good anti-freezing performance. The valve is a ventilation device installed on the fixed top tank to reduce the evaporation loss of oil and control the pressure action of the tank. The valve has large ventilation, small leakage, corrosion resistance, good anti-freezing performance. It can automatically adjust the pressure inside and outside the oil storage tank. Gas flame arrester simple structure, light weight, easy maintenance, convenient installation. Water pressure test passed. Low temperature resistance and frost resistance qualified: the pressure disc, vacuum disc and sealing ring have no deformation after operating at -42℃ for 2 hours. Fully meet the standard requirements. In normal temperature 36℃ continuous operation for 72 hours, 10000 times, pressure disc, vacuum disc and guide rod contact surface without any wear and collision signs, guide rod lifting sensitive without stuck phenomenon.
