Problems solved by technology

Precipitated things are easy to accumulate continuously, which makes it very difficult for the valve core to move downward, and jamming phenomenon such as valve closing is not in place.
The anti-blocking effect of this type of valve is not significant, and this type of anti-blocking valve does not have multi-functionality and intelligence
[0005] In the prior art, the only way to remove and replace a clogged valve is time-consuming and labor-intensive, and the clogging of the valve can only be found when the valve is switched on or off, or after the equipment connected to the valve fails, even if the valve is removed and replaced at this time. Replacement has also had a very adverse impact on the life of the equipment and the production speed of the factory. What is worse may cause damage to the equipment and greatly increase the maintenance cost.

Abstract

The invention provides a one-way anti-blocking valve. The o ne-way anti-blocking valve comprises a valve body, a valve clack in the valve body to control a valve cavity to open and close, a rotary sealing cover mounted on the valve body and an anti-blocking unit mounted on the rotary sealing cover; a valve rod is mounted on the valve clack, and a handle is mounted at one end, extending out of thevalve body, of the valve rod; a first sealing boy mounted on the inner surface of the rotary sealing cover and a second sealing body mounted on the outer surface of the valve body fit tightly; an anti-blocking unit is arranged on one side of a liquid inlet of the valve body and comprises a sealing housing connected to the rotary sealing cover, a driving unit mounted on the sealing housing and an anti-blocking rod and a connecting rod mounted in the sealing housing. The anti-blocking unit of the anti-blocking valve can be replaced anytime and the anti-blocking unit is quite simple to replace; moreover, the anti-blocking valve intercepting or adsorbing enough blockage also can detect the blocking degree automatically, reminds a user to replace in advance and is quite intelligent.

Description

technical field [0001] The invention belongs to the field of valve equipment, in particular to a one-way anti-blocking valve. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that makes the medium (liquid, gas, powder) in the piping and equipment flow or stops and controls its flow; the valve or the pipeline The control components in the fluid delivery system have the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief. Valves for fluid control, from the simplest globe valve to various valves used in extremely complex automatic control systems, have various varieties and specifications, and can be used to control water, steam, oil, gas, mud, various corrosive substances, etc. Flow of various types of fluids such as media, liquid metals and radioactive fluids. [0003] Valve blockage is one of the common faults, especially in the occasion...
