Automatic valve with pressure relief protection structure and implementation method of automatic valve

Abstract

The invention discloses an automatic valve with a pressure relief protection structure and an implementation method of the automatic valve. The automatic valve comprises a pressure collection base plate, an installing plate and a gate opening device, when the valve needs to be opened, a T-shaped installing round block drives an air outlet rubber pad to move downwards under driving of a second threaded column by screwing an opening and closing rotating wheel, air stored in an L-shaped connecting cylinder, a first hard connecting pipe, a telescopic connecting long pipe and a second hard connecting pipe can enter a pushing inner groove, the compressed air pushes an air pressure pushing block, and when an operator rotates a circular rotating wheel, under pushing of a one-way circular rotating plate, an operator can rotate the circular rotating wheel in a more labor-saving mode. The invention further discloses an implementation method of the automatic valve with the pressure relief protection structure, when the water pressure in a pressure collection base plate is increased, the pressure can downwards press a pressing rubber pad, and the air in a communicating hole can enter the L-shaped connecting cylinder, the first hard connecting pipe, the telescopic connecting long pipe and the second hard connecting pipe through a second one-way valve.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an automatic valve with a pressure relief protection structure and an implementation method thereof. Background technique [0002] A valve is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of a flowing fluid medium, and a valve is a basic component in a piping system. Valve fittings are technically the same as pumps and are often discussed as a separate category. The valve can be operated manually or by handwheel, handle or pedal, and can also be controlled to change the pressure, temperature and flow of the fluid medium. Valves can operate continuously or repeatedly in response to these changes, such as safety valves installed in hot water systems or steam boilers. Valves are automatically controlled in more complex control systems as required by an external input (ie, adjusting the changing set point of the flow through the pipeline). ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an automatic valve with a pressure relief protection structure and its implementation method. This device is used to work, thereby solving the problem that when the water stop valve is opened in the above background, it is usually necessary to use external force to open the valve to realize water discharge. , not only is it troublesome to operate and consumes manpower, but also does not make good use of the water pressure, resulting in a waste of resources
