Abstract

The invention discloses an automatic reversing valve which comprises a valve body, a sliding valve element, a shell I, a piston, an inching switch I, a spring, a cover plate, a shell II, an inching switch II, a conical connector and the like. The sliding valve element triggers the inching switches at the two ends, piston air inlet and exhaust are achieved, the sliding valve element is driven to reverse, executing mechanisms such as electromagnets, motors and pneumatic mechanisms are not needed, automatic reversing can be achieved, the structure is simple, and the reversing frequency can be adjusted in a self-adaptive mode according to the gas pressure.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an automatic reversing valve. Background technique [0002] The application of industrial control scenarios is becoming more and more extensive, and the demand for automation equipment is also increasing. The control of automation equipment usually needs to be controlled by means of reversing valve drive. This control often requires actuators such as electromagnets, motors, and pneumatic mechanisms. Participation, unable to adapt to the application of passive control scenarios. Contents of the invention [0003] The invention provides an automatic reversing valve, which can automatically reversing without needing actuators such as electromagnets, motors and pneumatic mechanisms, and can self-adaptively adjust the reversing frequency according to gas pressure. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An autom...
