Ball valve

Abstract

The invention discloses a ball valve, and relates to the technical field of ball valves. The ball valve comprises an outer valve structure, wherein the outer valve structure comprises an outer valve body, and a water inlet pipeline and a water outlet pipeline are fixed outside the outer valve body; an inner valve structure is arranged in the outer valve body and comprises two sealing assemblies, and the sealing assemblies are connected with the outer valve body in a sliding mode; an inner valve assembly is arranged in each sealing assembly and rotationally connected with the corresponding sealing assembly; and one end of the outer valve body is rotationally connected with a first desilting assembly attached to the inner wall of the water inlet pipeline, and the other end of the outer valve body is rotationally connected with a second desilting assembly attached to the inner wall of the water outlet pipeline. Through the design of a two-way threaded rod, a valve element groove, the sealing assemblies and the inner valve assemblies, on one hand, synchronous rotation of the sealing assemblies and the inner valve assemblies can be carried out, flexible adjustment of the water flow is met, on the other hand, vertical separation of the two inner valve assemblies can be achieved, therefore, adjustment of the caliber of the valve element is achieved, and the blockage cleaning efficiency of the ball valve is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of ball valves, in particular to a ball valve. Background technique [0002] The opening and closing parts of the ball valve are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. [0003] After searching, the Chinese invention patent number is CN109139964B, an anti-clogging ball valve. There are two half-shells at the front and back. The lower ends of the two half-shells are connected by two ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a ball valve, through the design of the outer valve structure, the sealing assembly, the inner valve assembly, the first dredging assembly and the second dredging assembly, to solve the problem that the internal blockage of the existing ball valve can only be solved by Only disassembly of the ball valve can solve the problem of anti-clogging. It is impossible to adjust the caliber of the valve core by separating the valve core. problems with normal use
