The main characteristic of high pressure pneumatic control valve is what? High pressure pneumatic control valve is a kind of used in single cylinder hydraulic machine hydraulic automatic conversion valve. It includes the body, an oil inlet, two points left and right direction oil outlet ( 2 l 2 r) , whose character is: inside the body there is a slide can move around in the middle of the core, corresponding to the position of oil outlet valve body internal symmetric has two of the same points in the oil and oil cavity two of the same valves; Slide around core through sliding core shaft connection on both ends of the valve core ( 5. 2 l, 5。 2R) ； At the bottom of the body to be axis symmetric has two oil cavity ( 7 l 7 r) And the upper left cavity filling ( 7 l) Tong oil cavity at the upper right points oil cavity ( 7 r) Tong left oil cavity; The oil cavity around ( 7 l 7 r) With around the top of the oil return valve ( 8 l, 8 r) About the oil return valve ( 8 l, 8 r) Movement control is through a conversion mechanism and the valve core cant transition steps connected; At the bottom of the two oil cavity around also equipped with suction valve. Using the utility model does not need to rely on the motivation of switching power supply. Supporting type less, can reduce the manufacturing cost of 40%, suitable for different style of motivation.
