Explosion-proof valve capable of rotating by 360 degrees

Abstract

The invention discloses an explosion-proof valve capable of rotating by 360 degrees. The explosion-proof valve comprises a valve body, a water inlet, a water outlet, a control valve element and a water channel. The valve body is divided into a first valve body part, a second valve body part and a third valve body part. The first valve body part is provided with a containing cavity. The containing cavity is provided with a first opening and a second opening in the axial direction of the first valve body part. The control valve element is inserted into the containing cavity through the first opening and closes the first opening. The containing cavity is provided with a third opening in the radial direction of the first valve body part. The second opening and the third opening are controlled to be connected or disconnected through the control valve element. The second valve body part is arranged on a first sealing ring and a second sealing ring of the first valve body part in a sleeving mode through a first through hole so that the second valve body part can rotate by 360 degrees relative to the first valve body part and the third valve body part. The third valve body part is fixedly connected with a first connecting section through a second connecting section. The explosion-proof valve has the characteristics of convenient mounting and better performance guarantee.

Description

technical field [0001] The invention relates to the field of valves, in particular to a 360-degree rotatable explosion-proof valve, which has the advantages of convenient installation and good explosion-proof performance. 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 enables or stops the flow of media (liquid, gas, and powder) in piping and equipment and controls its flow. Simply put, valves used in water flow can be divided into many types based on differences in application or function, such as angle valves, globe valves, butterfly valves, and gate valves. [0003] The valves all include a valve body and a control spool. The valve body is formed with a water flow channel, a water inlet and a water outlet. The water inlet and the water outlet are both connected to the water flow channel. The water port and the water outlet are connected to each other or cut off. [0004...

AI Technical Summary

Problems solved by technology

[0004] At present, the water inlet and outlet of the valves on the market are basically fixed. In order to realize the accurate connection between the water inlet and the water outlet and the corresponding connection ends, the threaded connection on the water inlet or the water outlet is often over-tightened. Since the threaded connection itself is thinner than other parts, coupled with excessive tightening, after a period of use, the threaded connection will become a breakpoint, causing the entire valve to collapse
