valve installation

The assembly method of the valve can be divided into screw-on type, compression type and snap-on type. For example, the assembly of the rubber valve is a snap-on type, and the valve base is provided with a card slot to fix it with the rim, which also leads to its one-time use, and once it is removed, it cannot be used again. The metal valve is assembled by screw-on, and the valve is fixed by a gasket and a fastening nut, and can be reused after being removed.
