Abstract

The invention discloses an elastic hard-sealing three-section forged steel fixing ball valve. The elastic hard-sealing three-section forged steel fixing ball valve comprises a valve body, two valve decks arranged on the two sides of the valve body, a spherical body arranged in the valve body and provided with a middle through hole and a valve seat arranged on the valve decks. The valve seat is made of metal, the section of the valve seat is of a C shape, and the opening of the valve seat is formed in the side away from the spherical body. According to the invention, the floating valve seat design is adopted, the directionality of liquid inflowing is overcome, and the two sides can be sealed well; the inner ring side of a supporting ring is set to be of a shape formed by matching a linear section and an arc section, and therefore the valve seat can constantly protrude outwards, full-time effective sealing can be guaranteed, and the use effect at high temperature can be improved.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to an elastic hard seal three-stage forged steel fixed ball valve. Background technique [0002] High-pressure ball valves are mainly used for high-pressure media such as high-pressure water, hydraulic oil, chemical high-pressure media, etc., to control the opening and closing of such media systems. Existing high-pressure ball valve mainly comprises valve body, bonnet, first valve seat, second valve seat, valve stem, handle, the sphere that has middle through hole, bonnet is connected with valve body, first valve seat, second valve seat The seat is set in the valve body, the ball is set between the first valve seat and the second valve seat, and a valve stem mounting groove is set on the outer surface of the ball, one end of the valve stem is set in the valve stem mounting groove, and the other end passes through the valve body Afterwards, it is connected with the handl...
