Abstract

The invention relates to a bi-directional sealed V-shaped regulating ball valve which comprises a valve body. The valve body is equipped with a valve cavity; a first opening and a second opening are respectively formed on two ends of the valve cavity corresponding to the valve body; the valve cavity is equipped with a left valve seat and a right valve seat, the right valve seat is adjacent to the second opening, and the left valve seat is adjacent to the first opening; a valve ball is arranged between the left valve seat and the right valve seat and can rotate relative to the left valve seat and the right valve seat; the valve ball is equipped with an installation groove and a V-shaped channel in a concave manner; the valve ball is equipped with the valve rod, and one end of the valve rod is equipped with a mounting block; and the shape of the mounting block is coincided with that of the installation groove, and the valve rod is arranged in the installation groove of the valve ball by virtue of the mounting block at an end part. The valve ball of the invention can close the passage between the first opening and the second opening; the valve ball is equipped with the V-shaped channel, and the V-shaped channel has shearing action on fluid medium according to percentage flow characteristics and can provide accurate regulation on medium circulation in the valve cavity; and the valve ball has good bi-directional sealing capability and can adapt to higher differential pressure.

Description

technical field [0001] The invention relates to a regulating ball valve, in particular to a two-way sealing V-shaped regulating ball valve. Background technique [0002] With the development of the economy, the level of industrial automation control is constantly improving, so the requirements for the valve adjustment function and reliability in process control are also constantly improving. In the prior art, some spherical ball valves with a V-shaped notch have poor adjustment function, and the anti-deformation ability of the valve ball is not ideal, and the operating pressure difference of the valve is not high. The limitations of its functions in actual use may affect the normal operation of the equipment and even cause huge economic losses. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a two-way sealing V-shaped regulating ball valve, which has good deformation resistance, can effe...
