Anti-leakage sealing valve

Abstract

The invention relates to a valve, in particular to an anti-leakage sealing valve. The anti-leakage sealing valve comprises a valve body, a stand column, a sliding shaft, a sealing plug, a liquid inletcavity, a liquid inlet, a liquid outlet cavity and a liquid outlet; the stand column is fixedly connected to the top end of the valve body, and a sliding cavity is formed in the middle of the stand column; the sliding shaft is connected to the interior of the sliding cavity of the stand column in a sliding mode, the sliding shaft seals the lower part of the sliding cavity to form a first sealingcavity, and a tension spring is arranged between one end of the sliding shaft and the top end of the valve body; the sealing plug is fixedly connected to one end of the sliding shaft, the sealing plugcan slide along the inner wall of the valve body, and a pit is formed in the side wall of the sealing plug; and the liquid inlet cavity is formed in the left side of the side wall of the valve body,and one end of the liquid inlet cavity is in communication with the interior of the valve body. According to the anti-leakage sealing valve, a one-way water absorption valve and a one-way water outletvalve are arranged and used cooperatively, so that the sealing plug firstly seals the liquid inlet cavity and the liquid outlet cavity for half edges, then the liquid inlet cavity and the liquid outlet cavity are sealed instantly and completely, and thus the sealing effect is good; and the anti-leakage sealing valve is simple in structure, convenient to operate, convenient to install and good insealing and anti-leakage effects.

Description

technical field [0001] The invention relates to a valve, in particular to an anti-leakage sealing valve. Background technique [0002] At present, the valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium, and is a control component in the fluid conveying system. Functions such as preventing reverse flow, stabilizing voltage, diverting flow or overflowing and releasing pressure. In valve technology, self-sealing valves occupy an indispensable position, but in self-sealing valves, often due to long-term use, the sealing material is damaged and consumed due to friction, which makes the valve seal not tight, resulting in liquid leakage; at the same time , There are impurities in the fluid in the existing valve, which will block the valve, thereby affecting the function of the valve and reducing the service life of the valve.

AI Technical Summary

Problems solved by technology

[0004] In this technical solution, a boss is provided inside the middle cavity, the protrusion on the upper end of the gasket coincides with the boss, and packing is provided at the joint between the valve stem and the upper cover, and the packing is pressed by the gland to improve the sealing of the valve. However, the valve is manually rotated so that the sealing plug slowly cuts off the water flow, and only one layer of gasket is used for sealing, so the sealing effect of the valve body is poor, and at the same time, due to the effect of water pressure, the user consumes a lot of physical strength
