Description

Technical Field

[0002] The valve flow detector is a device used to detect the flow of the valve. The existing ball valve flow detection method is relatively cumbersome. It is necessary to thread the pipe and connect the ball valve to form a water closed loop for detection, which is time-consuming and costly. The present invention adopts hollow telescopic cylinder technology. The cylinder is telescopically connected to the ball valve to quickly form a water closed loop, so that the ball valve can be quickly tested for qualification and quickly replaced.

[0003] Existing ball valve flow testing requires threading the pipe first, then connecting the ball valve to create a closed water loop. Threading itself is complex, requiring specialized tools and skills, and is time-consuming. Connecting the ball valve can also be delayed due to improper operation or mismatched parts. These factors combine to inefficiently test the entire process, significantly increasing time and costs.

[0004] Therefore, the existing technology has problems and shortcomings such as complicated detection process and high detection time cost.

[0005] In view of the shortcomings of the above solution in actual production and implementation, we have revised and improved it. At the same time, in the spirit and concept of striving for excellence, and with the assistance of professional knowledge and experience, as well as after many ingenuity and experiments, we specially provide a ball valve flow tester to solve the problems of cumbersome technical testing procedures and excessively high testing time and cost.
