VALVE AND VALVE CARTRIDGE ASSEMBLY THEREOF

摘要

A valve core assembly comprises a valve core (9) and a transmission device. A recess (90) is formed on the top of the valve core. The transmission device is provided in the recess (90) of the valve core. A first transmission relationship and a second transmission relationship are formed between the transmission device and the recess (90) of the valve core. The first transmission relationship is established so that the transmission device drives the valve core (9) to rotate axially. When the movement in the first transmission relationship is ended, the relationship between the transmission device and the valve core (9) switches from the first transmission relationship to the second transmission relationship. The second transmission relationship is established so that the transmission device drives the valve core (9) to carry out an extrusion movement, and the extrusion movement enables the valve core to have a moving component at least in an axial direction. The valve core assembly is simple in structure and can provide an opening and closing operation with a low torque. And also disclosed is a valve with the above-mentioned valve core assembly.
