Novel valve capable of automatically detecting sealing performance

Abstract

The invention discloses a novel valve capable of automatically detecting sealing performance. The novel valve capable of automatically detecting the sealing performance comprises a main valve body, aconnecting valve body is fixedly connected to the outer circle face of the main valve body, a valve element cavity is formed in the main valve body, a circulation cavity which is in communication withthe lower side of the valve element cavity and is through left and right is formed in the connecting valve body, a bottom cavity is formed in the lower side of the circulation cavity in a communicating mode, the upper wall of the valve element cavity is in threaded connection with a screw rod extending upwards to the upper side of the main valve body, the lower end face of the screw rod is rotationally connected with a valve element which is in up-down sliding connection with the valve element cavity and can extend into the bottom cavity, a water wheel cavity is formed in the valve element, and the lower side of the water wheel cavity is provided with a communicating cavity in a communicating mode. The water absorption material is driven to descend when a water outlet cavity is closed through ascending of the valve element, so that the sealing performance of the valve element is detected through changes of the water absorption degree and weight of the water absorption material, the water absorption material is folded when the valve element descends, and water flow is used for generating electricity.

Description

technical field [0001] The invention relates to the related field of new valves, in particular to a new valve capable of automatic detection of sealing performance. Background technique [0002] In our life, the valve is an important tool to control the opening and closing of domestic water. In industrial production, the valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. If the valve occurs Water leakage caused by sealing problems may waste a lot of time and resources, and may even lead to water cut-offs that affect life and production, causing a huge impact. It is difficult for some existing valve airtightness testing equipment to better test the airtightness of valves, and it is difficult to use water flow to generate electricity, resulting in a large waste. The present invention sets out to solve the above-mentioned problems. Contents of the invention [0003] In ord...
