Abstract: A valve assembly includes a sensing device, a main spring, a bonnet located below the sensing device, a piston with a through hole, and a valve stem connected with the sensing device and having a penetrating part through the through hole. The sensing device drives the valve stem to drive the piston. The valve assembly also includes an auxiliary spring arranged between the bonnet and the piston. The penetrating part is longer than the depth of the through hole and the valve stem is slidably coupled in piston. The valve assembly can prevent the valve stem from transferring the force of the main spring to the piston, so as to avoid damaging the valve port, the valve stem, and the piston when the force of the main spring is too large.

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