Problems solved by technology
[0002] After the existing ball valve is closed, liquid medium still accumulates in the valve chamber of the ball valve, which will not only cause corrosion to the valve body and reduce the service life of the ball valve, but also in cold weather, the liquid medium may solidify, making the ball valve stuck and unable to open , affecting the normal use of the ball valve
The ball diameter of the existing general-purpose ball valve is generally 1.4 to 1.6 times the diameter of the ball channel. The ball needs to be rotated by 70° to 80° from full opening to medium closure, and the rotation angle is large, which is inconvenient to use.

The invention discloses an anti-freezing quick ball valve which comprises a valve body, a valve cover, a valve rod, a handle and a ball body. The valve body comprises a valve cavity, a buffering channel and a valve body channel. The ball body is arranged in the valve cavity. A ball body channel is arranged in the ball body. The buffering channel is arranged between the ball body channel and the valve body channel. The valve rod is fixed on the ball body. A first sealing piece is arranged between the valve rod and the valve body. A second sealing piece is arranged between the valve rod and the valve cover. The second sealing piece comprises a sealing ring and an annular groove. A third sealing piece is arranged on the contact face of the valve cover and the valve body. A fourth sealing piece is arranged between the valve body and the ball body. A connecting rod is welded to the bottom of the ball body. The lower end of the connecting rod is welded with a blocking disc. A groove corresponding to the blocking disc is formed in the bottom end in the valve body. Two notches are formed in the blocking disc symmetrically. Liquid discharging holes corresponding to the notches are formed in the bottom of the valve body. Dustproof nets are arranged at the bottom ends of the liquid discharging holes. The ball valve is convenient to open and close, and the ball valve can be prevented from being frozen in cold weather.
Description
technical field [0001] The invention relates to a ball valve, in particular to a quick antifreeze ball valve. Background technique [0002] After the existing ball valve is closed, liquid medium still accumulates in the valve chamber of the ball valve, which will not only cause corrosion to the valve body and reduce the service life of the ball valve, but also in cold weather, the liquid medium may solidify, making the ball valve stuck and unable to open , Affect the normal use of the ball valve. The ball diameter of the existing general-purpose ball valve is generally 1.4 to 1.6 times the diameter of the ball channel. The ball needs to be rotated by 70° to 80° from full opening to medium closure, and the rotation angle is large, which is inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to provide an anti-freezing quick ball valve to solve the problems raised in the above-mentioned background technology. [0004] To achieve ...
