Description

Technical Field

[0001] The utility model relates to the technical field of fluorine-lined ball valves, in particular to a fluorine-lined ball valve. Background Art

[0002] The fluorine-lined ball valve uses a sphere with a circular through hole as the opening and closing part. The sphere rotates around the center line of the valve body with the valve stem to open and close the valve. A special molding process is used to make the sealing surface dense and good. In addition, the V-type PTFE packing combination makes the valve achieve zero leakage. The sphere and the valve stem are cast as one, eliminating the possibility of the valve stem rushing out of the pressure-bearing part due to pressure changes.

[0003] The Chinese patent application number CN202223070221.5 discloses an anti-clogging fluorine-lined ball valve, which relates to the technical field of connecting ball valves. The inner flow groove is arranged at the middle temperature position below the main body of the fluorine-lined ball valve, and an inner limit block is arranged on one side of the inner flow groove, and the inner limit block is fixedly connected to the main body of the fluorine-lined ball valve.

[0004] However, the above-mentioned prior art still has some shortcomings in actual use. When the above-mentioned prior art is used, if the screen needs to be disassembled and cleaned, the external pipe connected to the valve body needs to be disassembled before the screen inside the valve body can be taken out and cleaned. After cleaning, the external pipe needs to be re-fixed and connected to the valve body, which is quite troublesome. For this reason, we propose a fluorine-lined ball valve. Utility Model Content
