Detailed Product Description: | Wind pressure relief valve installation package necessity: the air bag pressure relief valve is used in the engine room of the wind pressure on the gas tank (tank also called air bag), why should the air bag on the tank pressure relief valve it ? This is because the air compressor in the air, it is easy to bring the coal mines, and oil inside the compressor with compressed air may enter the tank, the pressure inside the tank is relatively large, the relative temperature will be relatively high. When these pulverized fuel-air mixture in the case of high temperature and pressure, it is very prone to burn, even explosive situation. This happens inside the tank, the temperature will instantly rise, then the gas tank is very dangerous. In order to prevent this danger appeared, so the air bag should be installed on the tank pressure relief valve. QHF series air bag pressure relief valve consists of: cylinder, piston group, protective cover and other components. Cylinder from the left and right ends of the cylinder block group flanges and welded. In order to enhance the abrasion resistance and prevent rust, the inner surface of the cylinder of stainless steel. Piston group consists of card board, 0-ring, piston, rod and other components. From the left cylinder piston group and through the card board into the piston in the cylinder fixed set, make it impossible to move around. Protective cover from the flange, Simplified and welded door group. QHF series air bag pressure relief valve works: When the pressure relief valve pressure release, the protective cover prevents the piston flying out, play a security role. When the compressor system to work, the system pressure ≤ 0.785 (8kg/cm2), under this pressure, pressure release valve to work properly. When the air bag due to fire or coke for some reason explosive gas air bag, the system temperature, pressure transient rise, when the pressure rose to 1.03 ± 0.049MPa (10.5 ± 0.5kg/cm2) immediately when the lever pull off, the pressure relief valve pressure relief. Air bag and the line of high gas rapidly released from the surface to help ease the explosive shock wave, to avoid accidents role. QHF series air bag pressure relief valve models Category: QHF-50, QHF-65, QHF-80, QHF-100, QHF-125, QHF-150, QHF-200, QHF-250 pressure relief valve use and routine maintenance : 1, normal working hours, the air compressor system pressure should not exceed the working pressure of the air bag is ≤ 0.785 (8kgf/cm2) 2, always check the pressure relief valve cylinder, piston, flange connections and piping, should leakage phenomenon, the fastening parts should not be loose. 3, pressure release valve normal working hours, once a month extension of thin rod, rust situation every six months to replace a pressure relief valve inside the cylinder. 4, the pressure relief valve pressure relief direction is right not to pedestrians, equipment and consumable objects, pressure relief valve to prevent pressure release caused by an accident. Procurement Use Note: a, (procurement) a first air bag pressure relief valve not less than the diameter of the air bag gas tank out of the wind pipe diameter. To confirm the connection packet tank pipe diameter; 2, followed by the normal operation of the air compressor to know how much air pressure MPa, the normal working pressure packets tank; 3, the last air bag pressure relief valve must be pressure container production licenses unit production. Second, (when used) 1 air compressor system pressure should not exceed 7.84 × 105pa (8kg/cm2) 2. Always check the pressure relief valve cylinder, piston, flange connections and piping, to see whether the leak is loose. 3 should be regularly inspected, maintained. 4 normal working hours, once a month extension rod fine, rust situation. 5 Check the O-ring and sealing elastic case. If the rod replaced every six months, the better. 6 If severe corrosion or obvious relief extended fine should be replaced |
