Valve convenient to observe and observation method thereof

Abstract

The invention discloses a valve convenient to observe and an observation method thereof. The valve comprises a valve body, the surfaces of the two ends of the valve body are fixedly sleeved with mounting rings correspondingly, mounting holes are formed in the right sides of the mounting rings correspondingly, the top of the valve body is fixedly provided with a square pipe in a communicating mode,a groove is formed in the bottom of the inner cavity of the valve body, a threaded rod is arranged at the top of the square pipe in a penetrating mode, the bottom of the threaded rod penetrates to the inner cavity of the square pipe and is movably connected with a valve plate through a bearing, and the threaded rod is in threaded connection with the square pipe. The valve solves the problems thatan existing valve convenient to observe is prone to being damaged by external impact factors due to the fact that no protection device is arranged and the valve basically does not have the filteringfunction, when fluid passing through the valve contains fixed particles, the particles are prone to accumulating at the position of a valve core to cause blockage of the valve, and even if the valve has a filter screen for filtering, the filter screen cannot be cleaned for a long time, so that the particles are accumulated at the hole positions of the filter screen to severely hinder fluid distribution.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve that is convenient for observation. Background technique [0002] The valve is a key control component in the fluid delivery system. It has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. The valves used in the fluid control system range from the simplest cut-off valve to the extremely Various valves used in complex automatic control systems have a wide variety of varieties and specifications. Valves can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. A glass window is inlaid on the surface of the valve to facilitate the observation of the inside of the valve, but the existing valves that are easy to observe are easily damaged by external impact factors without protection devices, and basically do not have the func...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a valve that is easy to observe, which has the advantages of protection, filtration and cleaning of the filter net, and solves the problem that the existing valve that is easy to observe is easily damaged by external impact factors because there is no protection device, and basically does not It has the function of filtering. When the fluid passing through the valve contains fixed particles, the particles are easy to accumulate at the position of the valve core, causing the valve to be blocked. The location of the holes, a problem that seriously hinders the flow of fluid
