Embodiment

[0025] Embodiment: When installing the valve body 1 and the pipeline 2, by moving the pipeline 2, the pipeline 2 drives the second annular plate 4 to move, and the second annular plate 4 drives the limiting plate 15 to enter the first through hole 6, and the limiting plate When 15 enters the first through hole 6, squeeze the tapered surface of the fixing plate 9, so that the fixing plate 9 enters the first groove 7, until the fixing plate 9 is under the elastic force of the spring 10 and the limit plate 15 side wall is opened. The bit groove 16 is clamped and set, and finally the latch 14 is inserted to fix the position of the fixed plate 9, and then the sealing sleeve 15 is moved to make the sealing ring 18 tightly fitted on the joint of the first annular plate 3 and the second annular plate 4 , improved sealing, when it is disassembled, move the sealing sleeve 15, then take out the latch 14, pull the handle 13, the handle 13 drives the push plate 12, the push plate 12 drives ...

Abstract

The invention belongs to the field of valves, and particularly relates to a high-performance regulating valve. In order to solve the problems that in the case of installation of a valve in the prior art, connection is performed through a flange, then the installation and disassembly are relatively troublesome, and a connection portion is prone to be frozen, the following scheme is provided presently. According to the scheme, the high-performance regulating valve comprises a valve body, pipelines are arranged on the two sides of the valve body, first annular plates which are vertically arrangedare welded at the two ends of the valve body, second annular plates which are vertically arranged are welded to the side walls of the sides, close to the valve body, of the pipelines, sealing sleevesare arranged outside the pipelines in a sleeving mode, first through holes are formed in the side walls of one sides of the first annular plates, first grooves are formed in the side walls of one sides of the first through holes, and fixing mechanisms are arranged inside the first grooves. According to the high-performance regulating valve, the valve and the pipelines can be rapidly connected andinstalled, the operation is simple, the operation of performing fixation through screws is not needed, so that convenience is improved, meanwhile, disassembly can be performed conveniently, moreover,the sealing performance and the freezing resistance of the connection portions of the valve and the pipelines are improved, and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high-performance regulating valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. [0003] When the existing valves and pipelines are installed, they are often fixed by flanges. The installation and disassembly of flanges are very troublesome, and 6-12 screws need to be tightened and loosened repeatedly. Moreover, after the screws have been used for a period of time, It is prone to rust, slippage, etc., making it even more inconvenient to operate, and now there are valves and pipelines that are easily frozen in winter. For this reason, we have proposed a high-performance regulating valve. Contents of the inve...
