Referring to fig. 1, the angle type pneumatic switch stop valve of the present invention includes an angle type stop valve, which includes a valve body 1 and a valve rod 2 disposed in the valve body 1. An angle-shaped valve core 5 is arranged at the lower end of the valve rod 2. The valve body 1 is provided with a liquid inlet channel 3 and a liquid outlet channel port 4. The angle-shaped valve core 5 is sealed on the liquid outlet channel port 4.
A pneumatic actuator 6 for controlling the movement of the valve rod 2 is connected to the valve body 1. The pneumatic actuator 6 drives the angle-shaped valve core 5 to seal and open the liquid outlet channel opening 4 by controlling the movement of the valve rod 2. The pneumatic actuator is provided with an electromagnetic valve 7 and a compressed air pipeline 8. The compressed air pipeline 8 is externally connected with compressed air. The electromagnetic valve 7 is arranged on the pneumatic actuator 6. The compressed air pipeline 8 is communicated with the pneumatic actuator 6 through the electromagnetic valve 7. The electromagnetic valve 7 controls the on-off of the compressed air pipeline 8 to control the action of the pneumatic actuator 6. The installation of the electromagnetic valve 7 can realize the automatic control of the diagonal stop valve.
