Embodiment Construction
[0013] The present invention will be described in further detail below by means of specific embodiments:
[0014] The reference signs in the accompanying drawings of the description include: valve body 1, valve core 2, first induction piece 3, end cover 4, second induction piece 5, slide plate 6, spring 7, guide rod 8, second flow channel 9, Electromagnet 10, guide seat 11, first flow channel 12, sealing ring 13, valve seat 14, iron block 15.
[0015] The embodiment is basically as attached figure 1 As shown: the spring 7 induction check valve in this embodiment, the valve body 1 is respectively provided with a first flow channel 12, a second flow channel 9 and an intermediate flow channel that can communicate with the first flow channel 12 and the second flow channel 9. The first flow channel 12, the middle flow channel and the second flow channel 9 are arranged in a U shape, the first flow channel 12 is a stepped channel with a large outside and a small inside, and the seco...

The invention discloses a work method of a spring induction type check valve and aims to resolve the problems that according to an existing check valve, a spring is prone to failures, the compressing force of a valve element is insufficient, and the valve can not be fully closed. According to the work method of the spring induction type check valve, when a spring is in a natural state, a slider makes contact with a first induction piece, a loop of an electromagnet is controlled to be powered on through signals of the first induction piece, the electromagnet on a valve seat is powered on and attracts an iron block located on a valve element, the end surfaces of the valve seat and the valve element are tightly attached, and the valve is closed. When liquid enters a first runner, a guide seat in a cavity of the valve element is pushed to move in the axial direction of the valve element under the hydraulic action, the guide seat compresses the spring, and the spring pushes the slider to move. When the slider touches a second induction piece, the loop of the electromagnet is controlled to be powered off through signals of the second induction piece, and the electromagnet is powered off. At the time, the valve element is pushed to move under the hydraulic action, the valve element is separated from the valve seat, the first runner is communicated with a second runner, and the valve is opened.
Description
technical field [0001] The invention relates to one-way valve technology, in particular to a working method of a spring-inductive one-way valve. Background technique [0002] One-way valve is also called check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air. The main structure of the existing one-way valve includes a valve body, on which a liquid channel with a stepped longitudinal section is opened, and a valve seat is arranged at the step of the liquid channel, and the valve seat faces the liquid channel on the larger diameter side. , in the liquid channel on the larger diameter side, there is a valve core that can cooperate with the valve seat to open and close the liquid channel. When the channel is closed, the pressing force of the valve core against the valve seat is provided by a spring. The problem with the traditional one-way valve structure is: long-term us...
