[0002] In life, it is often necessary to control the on-off status of liquids. However, because there is a pressure difference when the liquid is conducted, when the pressure at the input end of the stop valve is lower than that at the output end, liquid reflux will occur. Once the liquid refluxes, it may cause contamination to the liquid outside the input end of the stop valve, resulting in a waste of resources.

[0003] At the same time, the utility model with application number 201921578388.8 discloses an integrated check stop valve, including a valve body, a fixed plate, a slider and a connecting plate, a rotating shaft is installed on the valve body, a rotating disk is installed on the rotating shaft, a driving rod is installed on the rotating disk, a receiving block is installed on the driving rod, a rotating handle is installed on the receiving block, and a protective pad is installed on the rotating handle, the fixed plate is installed on the valve body, and the fixed plate and the rotating shaft are mutually fitted, and the fixed plate and the driving rod are mutually fitted, and the driving rod and the moving block are mutually fitted, the slider is installed on the moving block, and the slider and the track are mutually fitted, and the track is installed on the fixed plate, and a working spring is installed at the bottom of the moving block.
