Anti-blocking valve

Abstract

The invention discloses an anti-blocking valve. The anti-blocking valve comprises a valve body, a valve core, a valve rod, a handle, an upper cavity, a lower cavity, a water inlet, a water outlet, a first filter net, a second filter net, a side pipe and a small valve; the water inlet and the water outlet are respectively formed in the two ends of the valve body; the first filter net is arranged at a water inlet end; the second filter net is arranged at a water outlet end; the valve core is arranged in the valve body; the upper end of the valve core is connected with the valve rod; the upper end of the valve rod is connected with the handle; the valve rod penetrates through the upper end of the valve body from the upper end; the upper cavity and the lower cavity are respectively formed in the centre of the valve body; the lower cavity is communicated with the water inlet; the side wall of the water inlet end is connected with one end of the side pipe; the other end of the side pipe is connected with the upper cavity in the centre of the valve body; the small valve is arranged on the side pipe; the valve core is matched and sealed with each of the lower end of the upper cavity and the upper end of the lower cavity. The anti-blocking valve is simple in structure, convenient to use, easy to operate and good in anti-blocking effect; emergency conveying is realized.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an anti-blocking valve. Background technique [0002] Valve (Valve) is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of the flowing fluid medium. Valves are the basic components in the 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. [0003] In the prior art, the valves used are often blocked due to more impurities in the fluid or corrosion and corrosion of the inner wall of the pipeline by the fluid, which affects the transportation capacity of the pipeline. When the above phenomenon occurs, the fluid transportation is generally suspended, and the valve is closed. Remove for cleaning and repair. However, in some c...
