Abstract
The invention relates to a high-pressure self-sealing valve. The high-pressure self-sealing valve comprises a valve body, a hand wheel and a valve cover. The valve body is provided with an inlet, an outlet and an operation opening. A front bracket and a back bracket which are siamesed are arranged in the valve body. The front bracket is provided with a valve port. The back bracket is provided with a through opening. A cylinder body, a valve rod and a cylinder rod are arranged between the front bracket and the back bracket. The cylinder body is fixed to the back bracket and provided with two sections of communicating hydraulic cavities which are formed in an included angle mode. One section of hydraulic cavity is provided with the sliding telescopic cylinder rod which faces towards the operation opening, and the other section of hydraulic cavity is provided with the sliding telescopic valve rod which faces towards the valve port. The cylinder rod is directional sliding relative to the valve body. The hand wheel is positioned rotating relative to the valve body. The hand wheel is in thread fit with the cylinder rod. The end, stretching out of the cylinder body, of the valve rod is connected with the valve cover used for sealing the valve port of the front bracket. When rotated, the hand wheel pushes the cylinder rod to compress the hydraulic cavities in the cylinder body and then pushes the valve rod to drive the valve cover to open the valve port, so that valve breakover is achieved. Conversely, self sealing of the valve cover under the stress of the inlet of the valve body is achieved, and sealing is reliable.
