Recently, Shanghai Wuyue pump and valve technology department analyzed that the main machine of the power plant wood-based panel scratch tester is mainly composed of a scale (1), a scale lifting mechanism (2), a rotary table (3), a frame (4), a weight (5), a scale radius adjusting mechanism (6), etc. the boiler safety valve leaks, the valve body joint surface leaks, and the main safety valve does not act after the impulse safety valve acts After the impulse safety valve is reseated, the main safety valve is delayed for a long time, the reseating pressure of the safety valve is low, and it is widely used in common fault causes such as frequency jump and flutter in railway, industrial and mining enterprises, scientific research institutes and other departments.
recently, Shanghai Wuyue pump and valve technology department analyzed the leakage of boiler safety valve, the leakage of valve body joint surface, the main safety valve does not act after the impulse safety valve acts After the impulse safety valve is reseated, the main safety valve delays reseating for a long time, and the reseating pressure of the safety valve is low, frequency jump and flutter. Solutions are proposed for the fault causes. In addition, these media belong to relatively viscous liquid technology, which has been popularized and applied
after several months of R & D and testing, Shanghai Wuyue has tested a series of new technologies for the failure of the above-mentioned power plant boiler safety valve, such as high-temperature resistant materials, ultra-high pressure internals and accessories, high-end material sealing 0 leakage technology, etc. This improved result also solves some common problems of leakage and insensitive high temperature and high pressure take-off during the application of the safety valve
Shanghai Wuyue Valve Manufacturing Co., Ltd. has made outstanding achievements in the field of safety valve manufacturing, and a number of improved technologies for old products have been widely used. In the field of safety valves for utility boilers, it has taken another innovative step and made significant contributions to the field of safety valves
