Application of Jet Pipe Servo Valve in China
As the jet valve servo valve design and manufacture have a certain degree of difficulty as well as foreign technology limitations of China's jet tube, the current domestic mass production, the development of servo valve only 704 institute. I produced CSDY series of jet flow servo valve has been developed for more than 30 years, its production technology, performance indicators have reached or close to similar foreign products. Has been widely used in ships and other industrial occasions. Has now begun in the aerospace, aerospace and other applications, such as the field of flaps air control systems, engine fuel system, front wheel steering cylinder movement direction and speed and so on. Our newly developed jet pressure servo valve has achieved some initial success. Its preamp uses a jet amplifier, which is mainly used in aircraft electronic anti-skid braking system to output brake pressure in proportion to the control signal. Before the domestic pressure servo valve without exception, are nozzle baffle structure, however, there is a fatal flaw, that is, anti-pollution ability, which is a major hidden trouble in the system. The successful development of jet pressure valve to make up for the nozzle baffle pressure servo valve in the pressure control defects and improve system reliability and stability. In summary, the jet pipe servo valve in the anti-pollution ability and other reliability characteristics are higher than the nozzle flapper valve. The working stability and durability of the jet pipe servo valve is quite high. At present, the servo valve I have produced has been applied in the field of aviation and aerospace. Believe that with the application of the jet pipe servo valve more widely, in aerospace and various industrial control applications will have a broad application prospects.
