The spring is a spiral spring.

The piston is a cylindrical step shaft.

The spring is pressed into the cavity of the piston cavity, and the outer diameter of the spring is in clearance fit with the inner diameter of the cavity of the piston cavity.

The small end of the step shaft of the piston is pressed into the spring, the outer diameter of the small end of the step shaft of the piston is in clearance fit with the inner diameter of the spring, the large end of the step shaft of the piston is pressed into the cavity of the piston cavity, and the diameter of the large end of the step shaft of the piston is in transition fit with the inner diameter of the cavity of the piston cavity.

The silica gel pad be circular thin slice structure, put into from the top surface screw hole of main part regulation chamber and cover inlet aperture and the aperture of giving vent to anger.

During the concrete implementation, install the inlet nozzle respectively with the outlet nozzle in the inlet screw hole of main part regulation chamber and the threaded hole of giving vent to anger, put into the bottom of top surface screw hole again silica gel pad from the top of main part regulation chamber, cover and cover inlet aperture and the aperture of giving vent to anger, then impress the spring in the cavity in piston chamber, the spring is impressed to the piston tip, the spring top is in the terminal surface department of piston main aspects, in the cavity in the piston chamber of impressing of piston main aspects, press to the big plane of piston bottom surface and the lower port parallel and level of piston chamber cavity, the piston that will assemble again, spring and piston chamber are together through the top surface threaded connection in piston chamber and main part regulation chamber, assemble into a whole. When the air conditioner does not work, the movable plug is naturally propped downwards due to the telescopic characteristic of the spring, and the piston tightly presses the silica gel pad due to the spring force, so that the small air inlet and outlet hole of the main body adjusting cavity is tightly sealed.
