Abstract
The solenoid valve of this invention comprises an electromagnet with a rotator disposed in at least one side of the valve body. The shaft of the rotator is provided with the valve members to open or close the valve port. The solenoid valve has advantages such as high attraction force, less power, and is easy to continuously control.
Claims5
A rotary gas solenoid valve comprising:
- a valve casing installed with an inlet valve port and an outlet valve port;
- a guarded rotary electromagnet mounted on a side of the valve casing, the guarded rotary electromagnet including an iron core, a coil, a rotary armature, and a seating;
- a valve support fastened at a position of an axial end of the rotary armature of the guarded rotary electromagnet corresponding with the outlet valve port or the inlet valve port;
- and
- a valve member mounted on the valve support,
- wherein a reset spring is mounted on the guarded rotary electromagnet, one end of the reset spring fixed on the iron core or the seating, another end of the reset spring mounted on a side of the rotary armature or an arm fastened with the axial end of a shaft of the rotary armature, and
- wherein an adjusting screw is installed on the reset spring.
