Problems solved by technology

The opening and closing part of the ball valve is a sphere. At present, the sphere is mainly made of carbon steel and other metals. When the ball valve is used in the transmission of corrosive liquid or gas, the sphere is easily corroded during long-term use, which affects the sealing effect of the ball valve.

Abstract

The invention discloses a ball valve element suitable for a corrosive medium. The ball valve element comprises a ball body main body; the ball body main body includes a valve shell and a runner cylinder; the valve shell is a hollow ball body, and is welded with a cylindrical valve rod connecting head at the top; and a valve rod connecting hole is formed in the top of the valve rod connecting head. Round holes with diameters equal to the inner diameter of the runner cylinder are respectively formed in the left and right two sides of the valve shell; the runner cylinder is arranged in the valve shell, and two ends thereof are respectively connected with the left and right round holes of the valve shell; multiple reinforcing ribs are fixed between the inner wall of the valve shell and the outer wall of the runner cylinder; and protection layers are attached on the outer wall of the valve shell and the inner wall of the runner cylinder. The ball valve element is higher in corrosion resistance, effectively prolongs the service life of a ball valve, and enables the ball valve to be more suitable for transmission of the corrosive medium.

Description

technical field [0001] The invention relates to a valve component, in particular to a ball valve core suitable for corrosive medium. Background technique [0002] The ball valve is a kind of valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. Currently known ball valves mainly include a valve body, a valve stem, a sphere and a sealing ring. The ball valve is sealed by the close contact between the sphere and the sealing ring, and the valve is opened and closed by rotating the sphere. The opening and closing part of the ball valve is a sphere. At present, the sphere is mainly made of carbon steel and other metals. When the ball valve is used for corrosive liquid or gas transmission, the sphere is easily corroded during long-term use, which affects the sealing effect of the ball valve. Contents of the invention [0003] In order to solve the above problems, the...
