Abstract

The invention relates to a switching valve. The switching valve comprises an electromagnetic driving device, an anti-reverse ratchet device, a reset device and a valve port switching device, wherein the anti-reverse ratchet device is used for outputting rotational motion along the circumferential direction of the electromagnetic driving device and rotating at a first preset angle under the axial driving action of the electromagnetic driving device; the reset device is coupled to an output end of the anti-reverse ratchet device and is used for resetting the anti-reverse ratchet device to an initial state along the circumferential direction of the electromagnetic driving device; the valve port switching device is used for realizing valve port switching under the driving of the rotational motion. According to the switching valve disclosed by the invention, the step-out problem caused by adopting a stepping motor in the prior art is avoided; the switching valve has the characteristics of high accuracy and low cost.

Description

technical field [0001] The invention relates to the field of valves, in particular to a switching valve and a control method thereof. Background technique [0002] Switching valves in the prior art usually use a stepping motor structure to switch their states. Since a stepping motor is used for state switching, there will be a step-out phenomenon during use, so it has the disadvantages of high precision requirements, high production costs and high material requirements. Contents of the invention [0003] The object of the present invention is to provide a switching valve and its control method which can avoid the out-of-step problem, have high precision and low cost. [0004] In order to solve the above-mentioned technical problems, as one aspect of the present invention, a switching valve is provided, including: an electromagnetic drive device; an anti-reversing ratchet device, which is used for outputting along the direction of the electromagnetic drive device under the...
