In the utility model, the stop valve can filter impurities contained in the medium to prevent the accumulation of impurities in the stop valve, which may cause blockage over a long period of time and affect normal use. The stop valve can detect its flow rate and automatically control the extension and retraction of the electric rod so that when the restoring force of the spring decreases, its movable block is pushed back to its original position, closing the stop valve. This makes it easier for staff to find the rupture and quickly carry out rescue and repair, thereby improving work efficiency and making it easier for staff to control and adjust the flow rate of the medium.
