Extension cleaning ball valve

Abstract

The invention discloses an extension cleaning ball valve, and belongs to the field of ball valves. According to the extension cleaning ball valve, by arranging a telescopic expansion rod capable of freely deforming in a valve body, when the inner wall of the extension cleaning ball valve needs to be cleaned, inflation operation can be conducted on the telescopic expansion rod outside under the condition that the extension cleaning ball valve is not disassembled, so that the telescopic expansion rod extends and expands to be in a linear state and penetrate through the two sides of a valve element, and the telescopic expansion rod is pulled by a pull rope to rotate in a single circle along the valve body and the valve element to clean the inner wall of the extension cleaning ball valve; and after cleaning is completed, the telescopic expansion rod is away from the valve element through contraction of the telescopic expansion rod, the rotary flow control process of the valve element is not prone to being hindered, and normal use of the extension cleaning ball valve is realized. Compared with the prior art, unnecessary mounting and dismounting procedures are avoided, and the rapid and effective inner wall cleaning process is achieved.

Description

technical field [0001] The invention relates to the field of ball valves, in particular to an extended cleaning ball valve. Background technique [0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates 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. This type of valve should generally be installed horizontally in the pipeline. [0003] The cleanliness of the circulating medium in the ball valve is difficult to strictly control. Therefore, after a long-...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide an extended cleaning ball valve, which can be controlled externally without disassembling the present invention by setting a freely deformable telescopic expansion rod inside the valve body. The telescopic expansion rod is inflated to make it stretch and expand in a linear state. By pulling the pull rope, the telescopic expansion rod rotates in a single circle along the valve body and valve core to clean its inner wall. The shrinkage of the rod keeps it away from the valve core, realizing the normal use of the invention. Compared with the prior art, the invention avoids unnecessary installation and disassembly procedures, and realizes a fast and effective inner wall cleaning process
