Abstract:
A fluid actuating valve composed of a valve body, a valve cap, a valve core assembly, a fluid-controlling pipe assembly and an actuating element, characterized in that: the valve body comprises a longitudinal tubular body and a transversal cylinder body, the longitudinal tubular body defines a fluid passage from the inlet to the outlet of the valve body, and the transversal cylinder body defines a valve chamber, a transversal well is disposed in the middle of the longitudinal tubular body for communicating the longitudinal fluid passage with the valve chamber, and the upper surface of the transversal well defines a valve plate eat, a valve core assembly is provided in the transversal well, which engages with the inner wall of the well and the valve plate seat and is lifted by the pressure fluid which comes from the valve inlet in a first direction to open the valve whereby said fluid flows in a second direction through the fluid passage and enters into the valve outlet, the second direction is the same as the first direction, a pressure-releasing hole is provided at the outlet side of the longitudinal tubular body to communicate the valve chamber with the longitudinal fluid passage at the outlet side whereby the fluid in the valve chamber enters into the outlet side of the longitudinal fluid passage while the valve assembly is moved down, an actuating element is installed in the valve chamber under the valve cap, which can drop the valve core assembly to shut the valve by the pressure fluid coming from the fluid-controlling pipe assembly.
