Valve is special equipment (boilers, pressure vessels, pressure piping, etc.) a limit on the pressure relief plays an important role in the security annex. General safety valve mounted directly on the special equipment, his design, manufacture, installation, use, testing, and other special equipment must comply with the relevant requirements, because it moves the reliability and performance is directly related to the equipment and personal Weifang safety valve, and is closely related to energy conservation and environmental protection. During normal use of the valve and verify, due to the design, manufacture or improper use can cause a variety of failures. These failures are not promptly removed, will affect the life of A40YC efficacy and safety valve spring safety valve, serious but also endanger the lives and safety of the user. 1, the valve leaks. Exceed the allowable level of leakage, causes and solutions occur valves and valve seat sealing surface: a, leakage because of stolen goods between spring valve and seat sealing surface safety valve, the valve can be more Open several times washed down the line. b, the sealing surface damage, the extent of damage can be repaired using abrasive grinding or turning method. c, curved stem, tilt Den. Should be re-fitted or replaced to maintain a safety valve to prevent the hammer moves have their own devices and limit leverage deviant guides, spring safety valve should enhance handle and prevent casual twist adjustment screw devices. 2, it should be mounted vertically in the highest position in the pot business, collection boxes. Between the valve and the drum or header shall be equipped with access steam outlet pipe and valves. 3, the connection pipe and the boiler safety valve, its cross-sectional area not less than the cross-sectional area of ??the valve imported. If several valves installed together on a short tube directly connected with the drum, short tube channel cross-sectional area should not step on all exhaust valve area 1.25 times.
