Abstract

A stepwise pneumatic digital valve comprises a valve base, a valve body and a stepping motor. The valve body is positioned inside the valve base, the valve body comprises a valve core and a valve jacket, the valve core is installed on the valve jacket and capable of conducting reciprocating movement in left and right directions, the output shaft of the stepping motor is connected with the input end of an eccentric mechanism, and the output end of the eccentric mechanism is linked with the valve core. The inventive stepwise pneumatic digital valve has the advantages of simple structure and low cost; and can directly realize digital control.

Description

technical field [0001] The invention relates to a pneumatic digital servo valve, which is suitable for pneumatic control occasions. Background technique [0002] Pneumatic technology has developed rapidly in recent years. In the process of developing new products, foreign enterprises have continuously improved their product competitiveness and sought to win by quality. The original traditional pneumatic components have gradually been replaced by new pneumatic components due to backward structure, large volume, poor reliability and other reasons. [0003] For the field of high-speed and high-precision pneumatic control, the traditional electromagnetic drive servo valve is expensive, has high requirements on the environment, and the output pressure is small, so it cannot realize direct digital control in control. Therefore, the traditional servo valve is used as the pneumatic control of the experimental system. Components have certain defects. Contents of the invention [...
