Valve with automatic positioning mechanism and using method thereof

Abstract

The invention belongs to the field of valves, and particularly relates to a valve with an automatic positioning mechanism and a using method thereof. The upper surface of a valve body is fixedly connected with an upper cover plate through a fastening nut, the lower surface of the valve body is fixedly connected with a lower cover plate through a fastening nut, and the side face of the valve body is fixedly connected with a water pipe. An adjusting mechanism is arranged in the valve body, and a sealing mechanism is arranged at the top of the adjusting mechanism. According to the valve with the automatic positioning mechanism, the sealing mechanism is arranged, when a rotating rod is inserted into the upper cover plate, the bottom end of the rotating rod extrudes sliding blocks towards the two sides, under the action of a buckle and a clamping groove, the sliding blocks slide towards the two sides, compression springs are compressed, and operation of the adjusting mechanism, a telescopic mechanism and a pneumatic mechanism is controlled through up-down movement and left-right rotation of the rotating rod. After the valve is closed, the rotating rod is pulled out, the sealing mechanism is stopped, and when the valve needs to be opened, the rotating rod is inserted again, so that the problem of valve leakage caused by accidental touch by external force can be prevented.

Description

technical field [0001] The invention belongs to the field of valves, and in particular relates to a valve with an automatic positioning mechanism and a use method thereof. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. [0003] The traditional valve handle is exposed outside and will be touched by external force intentionally or unintentionally, resulting in unstable flow. In order to avoid this kind of situation, the handle is usually removed, but due to the lack of positioning device, when the handle is inserted again, the card slot and the card The buckle is not easy to over...

AI Technical Summary

Problems solved by technology

[0003] The traditional valve handle is exposed outside and will be touched by external force intentionally or unintentionally, resulting in unstable flow. In order to avoid this kind of situation, the handle is usually removed, but due to the lack of positioning device, when the handle is inserted again, the card slot and the card The buckle is not easy to overlap, and it needs to be rotated repeatedly to align. Moreover, the traditional valve is purely mechanically fixed, and the inside is easy to block and the outside is easy to leak.
