Multi-channel high-pressure gas mechanical reversing mechanism

Abstract

The invention discloses a multi-channel high-pressure gas mechanical reversing mechanism. The multi-channel high-pressure gas mechanical reversing mechanism comprises a valve casing with a cylindrical through cavity, and a cylinder valve element plugged in the cylindrical through cavity of the valve casing in an interval mode, wherein multiple air outlets are evenly formed in the upper portion of the valve casing in the circumferential direction; each air outlet is fixedly connected with an air outlet pipe; an air inlet is formed in the lower portion of the peripheral surface of the valve casing; three annular grooves are formed in the peripheral surface of the cylinder valve element at intervals from top to bottom; an air outlet channel is formed at the position, between the first annular groove and the second annular groove, of the peripheral surface of the cylinder valve element and located at the height position of the air outlets; the air outlet channel extends to the axis position of the cylinder valve element; an air guide annular groove is formed in the position, between the second annular groove and the third annular groove, of the peripheral surface of the cylinder valve element and located at the height position of the air inlet; air inlet channels are formed in the bottom of the air guide annular groove in the radial direction; an air guide channel communicated with the air outlet channel is upwards formed in the junction of the air inlet channels. The multi-channel high-pressure gas mechanical reversing mechanism has the advantage that the purely mechanical structure is adopted, so that the fault problems that a traditional solenoid valve needs to be supplied with power and is switched uninterruptedly are solved.

Description

technical field [0001] The invention relates to a high-pressure gas reversing mechanism, in particular to a multi-channel high-pressure gas mechanical reversing mechanism. Background technique [0002] At present, in the field of mechanical engineering, the multi-way reversing mechanism of high-pressure gas mostly uses valves for reversing. Its structure is complex and bulky, and the use of many valves will lead to low reliability and difficult maintenance. In addition, due to the complex structure, it is very prone to problems, which not only require expensive maintenance costs, but also reduce work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a multi-channel high-pressure gas mechanical reversing mechanism. [0004] To achieve the above object, the present invention takes the following technical solutions: [0005] The multi-channel high-pressure gas mechanical reversing mechanism of the present invention includes a ...
