Pipeline control method of ball valve inflation detection device

Abstract

The invention discloses a pipeline control method of a ball valve inflation detection device. The pipeline control method is used for detecting the air tightness of a row of ball valves. The input end of each ball valve is provided with a branch inflation channel, each branch inflation channel is communicated with the main inflation channel, each branch inflation channel is provided with a one-way valve, and the one-way valves only allow air flow to pass from the main inflation channel to the ball valves; when the air tightness of the row of ball valves is detected, each ball valve is in an open state, the output end of each ball valve is closed, and the row of ball valves are inflated through the main inflation channel and the branch inflation channels. According to the invention, inflation detection can be carried out on a row of ball valves, and the efficiency of air tightness detection of the ball valves can be improved; the inflation pump can be started to inflate the first row of ball valves only by clamping the first row of ball valves through the left clamping plate and the right clamping plate; in the inflation detection process of a row of ball valves, opening and closing of valves on a pipeline do not need to be controlled additionally.

Description

technical field [0001] The invention relates to a pipeline control method of a ball valve inflation detection device. Background technique [0002] The ball valve is a valve with a ball as the opening and closing part, and the ball valve can be used to control the flow of gas. In order to ensure the air tightness of the ball valve, it is necessary to use a ball valve inflation detection device to perform inflation detection on the ball valve. However, the existing ball valve inflation detection device can only detect one ball valve at a time, which makes the air tightness detection efficiency very low. In addition, the existing ball valve inflation detection device generally performs inflation detection on the ball valve through the pipeline, and multiple valves are generally set on the pipeline. When the inflation detection of the ball valve is performed, each valve needs to be actively controlled, and the control process is relatively complicated. SUMMARY OF THE INVENTI...
