Abstract
A valve for pneumatic pressure regulating, fast decompression and multi-torch operation comprises a one-way throttling valve, an air inlet cover, an upper cover, a membrane cylinder assembly, a valve body assembly, a water inlet-outlet cube assembly and the like. When the valve is at work, compressed air is adopted as a power source, the membrane cylinder assembly is used, the closing clearance between a valve rod and a valve seat in the valve body assembly is adjusted by adjusting the inlet pressure of a cylinder in the membrane cylinder assembly, so that the spillway discharge is controlled, and the purpose of regulating pressure is realized. The valve integrates the functions of stable pressure regulating, fast decompression and multi-torch operation, and the designing principle of ''unidirectional throttle governing'' is adopted on the aspects of air inlet and air discharge of the cylinder, so that stable pressure boosting and fast decompression of a high-pressure water jet system are realized. No only are the service lives of main quick-wear parts (the valve rod and the valve seat) are prolonged, but also the safety of the water jet system is greatly improved. Furthermore, by adopting the valve, multiple torches can be operated, and do not interfere with one another, multi-torch conversion is small in pressure fluctuation, safe, stable and easy to operate.
