Abstract: A valve stem and valve core assembly and a valve including a valve stem and valve core assembly. The valve stem and valve core assembly includes a valve stem and a valve core that sleeves the valve stem. The assembly includes an adjusting device arranged on the valve stem, and an elastic element arranged between the adjusting device and the valve core. A clearance exists between the valve core, the valve stem, and the adjusting device, so that the valve core can move relative to the valve stem, such that the valve can have a good closing performance.

Abstract: A driving apparatus and a valve including the same. The driving apparatus senses a pressure of a fluid medium and generates a driving force. The driving apparatus includes: a drive shaft, a sensing device, a limiting device, a support body, and a protruding member. The limiting device includes a groove, and the protruding member is engaged in the groove. The limiting device can thus automatically limit the rotation of the drive shaft, so as to avoid damaging the sensing device, thereby facilitating maintenance and installation of the valve.
