Problems solved by technology

In the field of home improvement and bathroom, when the valve is connected to the washing machine, the connecting pipe is generally a hose, and the hose is connected to the outlet of the valve through the nozzle of the washing machine. When the hose falls off or bursts from the valve, if the valve is open, the water flow will It will flow out continuously, which leads to the waste of water resources. When the water flow is too large, it is easy to bring safety hazards
However, the valves in the prior art cannot automatically cut off the pipeline when the connecting pipe falls off or bursts.

Abstract

The invention discloses an anti-explosion and anti-disengagement valve assembly. The anti-explosion and anti-disengagement valve assembly comprises a valve body. A water inlet is formed in one end ofthe valve body, and a water outlet is formed in the other end of the valve body. A connecting pipe is connected to the water outlet. A limiting piece is arranged at the end, away from the water outlet, of the connecting pipe. A limiting boss is arranged on the inner wall face of the water inlet. A first spring and a sealing sliding block are arranged between the end of the water inlet and the limiting boss. The sealing sliding block comprises a sealing cap matched with limiting boss in a stopped mode and a fixing column fixedly connected to the middle of the sealing cap. The diameter of the fixing column is smaller than that of the sealing cap, and the fixing column is fixed in the first spring. One end of the first spring is fixedly connected to the limiting boss, and the other end of thefirst spring is fixedly connected to the sealing cap. A second spring is fixedly mounted in the water outlet. An anti-disengagement sealing block and an anti-disengagement block are connected to thesecond spring. A gap is formed between the anti-disengagement sliding block and the inner wall of the outer outlet. A stop edge matched with the anti-disengagement sliding block is arranged in the connecting pipe. A sealing ring matched with the anti-disengagement sealing block is arranged on the inner wall of the water outlet.

Description

technical field [0001] The invention relates to an explosion-proof and detachment-proof valve assembly, in particular to a valve assembly for automatically cutting off a pipeline when a connecting pipe bursts or falls off, and belongs to the technical field of valves. Background technique [0002] Valves are widely used in various fields and are indispensable parts in various fields. One end of the valve is a water inlet, the other end is a water outlet, and the water outlet is connected with a connecting pipe. In the field of home improvement and bathroom, when the valve is connected to the washing machine, the connecting pipe is generally a hose, and the hose is connected to the outlet of the valve through the nozzle of the washing machine. When the hose falls off or bursts from the valve, if the valve is open, the water flow will It will continue to flow out, which leads to the waste of water resources. When the water flow is too large, it is easy to bring safety hazards...
