Abstract

An energy-saving type precise pressure regulating valve improved structure comprises a body. A main membrane and a balance membrane are arranged in the body. The main membrane is mainly in linkage with an overflow pipe, and the balance membrane is in linkage with a pressure regulating straight rod. When gas flow enters the body, through a channel, a feedback channel and a pressure regulating channel which communicate with one another, by means of cooperation of a feedback channel throttling hole and steel balls in the feedback channel, pressure fluid is controlled to circulates unidirectionally, and through cooperation of a straight rod rubber coating on the pressure regulating straight rod and a membrane rubber coating on the main membrane, the pressure fluid circulates more rapidly as awhole; and besides, through cooperation of the overflow pipe and the overflow hole, rapid pressurization and decompression can be conducted, and high-precision output pressure can be provided.

Description

technical field [0001] The invention relates to an improved structure of an energy-saving precision pressure regulating valve, which mainly utilizes a feedback channel to flow in one direction to regulate the flow of pneumatic fluid, so that the feedback channel and the pressure regulating channel are in a balanced state, and is supplemented by The overflow pipe cooperates with the overflow hole to achieve rapid boosting, decompression and high-precision output pressure. Background technique [0002] Commonly used pressure regulating valves will consume a lot of pneumatic fluid during the process of pressure regulation. In order to meet the needs of more sophisticated automatic processing in the future, various manufacturers are focusing on research and development of related technologies that can save energy consumption during the process. In the "precision pressure regulating valve" of the previous patent No. M513296, the inventor set up passages inside the structure to al...
