Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to a regulating valve which is easy to assemble and disassemble. Background Art

[0002] A regulating valve is a valve used to control fluid flow, usually used in industrial process control and automation systems. It can change the fluid flow through the valve by changing the position of the valve core, thereby achieving flow regulation and control.

[0003] There are two types of regulating valves, large and small. Smaller regulating valves are directly connected to pipelines through threaded connections, while larger regulating valves are generally connected through connecting flanges. When connecting through flanges, the holes on the flanges on both sides need to be aligned. When the valves are connected, the pipelines are generally fixed first. After the pipelines are fixed, the flange on the regulating valve located between the two pipelines may not be well aligned with the holes on the flanges on both sides of the pipelines, which makes the installation of the regulating valve more inconvenient.

[0004] Therefore, the utility model provides a regulating valve which is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0031] An adjustment groove 26 is provided inside the collar 22, and a first bolt rod 24 is fixedly installed on the outside of the adjustment ring 27. The first bolt rod 24 penetrates the corresponding adjustment groove 26, and a first nut 23 is threaded on the outside of the first bolt rod 24. An extrusion sheet 25 is sleeved on the outside of the first bolt rod 24, and the first nut 23 is located on the outside of the extrusion sheet 25. The inner end of the extrusion sheet 25 is arc-shaped, and the inner end of the extrusion sheet 25 fits on the outside of the collar 22. The extrusion sheet 25 is made of non-slip rubber. The valve flange 4 is fixedly installed on the outer end face of the rotating ring 21, and the valve body 1 is connected to the rotating ring 21. The outer wall and inner wall diameters of the valve body 1 and the rotating ring 21 are the same.

[0032] In this embodiment, by loosening the first nut 23, the squeezing of the extrusion sheet 25 by the first nut 23 can be released, thereby releasing the fixation of the first bolt rod 24. After releasing the fixation, the first bolt rod 24 can be slid along the adjustment groove 26. During the sliding, the internal rotating ring 21 and the adjusting ring 27 rotate synchronously.
