Description

An easy-to-install regulating valve Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically to a regulating valve that is easy to install. Background Technology

[0002] Control valves are generally connected via flanges. When connecting via flanges, the holes on both flanges need to be aligned. However, when connecting valves, the pipelines are usually fixed first. After the pipelines are fixed, the flange on the control valve located between the two pipelines may not be able to align well with the holes on the flanges on the pipelines on both sides, which makes the installation of the control valve inconvenient.

[0003] Chinese patent CN202421321277.X discloses a regulating valve that is easy to disassemble and assemble. By sliding the first bolt rod along the adjusting groove, the internal rotating ring and the adjusting ring rotate synchronously during the sliding. The rotation of the rotating ring can change the angle of the outer valve flange. By changing the angle of the valve flange without changing the angle of the valve body, it is possible to ensure that the valve flange can be aligned with the fixed pipe flange, thereby ensuring that the flange hole can be accurately aligned during valve installation.

[0004] The flange can be rotated and its position adjusted by means of a first nut, a first bolt rod, a pressing plate, and an adjusting groove. However, it is only fixed by bolts and nuts. After long-term use, the bolts and nuts are prone to loosening, which affects the subsequent use effect.

[0005] Meanwhile, because the valve flange and valve body need to be rotated and adjusted, gaps will inevitably exist, which increases the risk of leakage over a long period of use.

[0006] Furthermore, the number of flange holes on different pipe flanges varies, with common types including 4-hole, 6-hole, and 8-hole flanges. It is not possible to replace the flange itself to match different pipe flanges; the entire valve body must be replaced, leading to increased costs.

[0007] Therefore, a regulating valve that is easy to install is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide an easy-to-install regulating valve to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install regulating valve, comprising a valve body, two outer shells symmetrically provided at the ends of the valve body, a flange portion provided on one side of the two outer shells, and flange holes evenly provided on the flange portion;

[0010] Both ends of the valve body are equipped with fixing blocks. The outer side of the fixing blocks is evenly provided with teeth, and the inner side of the two outer shells is evenly provided with grooves that match the teeth.

[0011] Preferably, an arc-shaped groove is provided on the other side of each of the two outer shells, and a fixing bolt is provided inside the arc-shaped groove.

[0012] Preferably, the fixing block has two threaded holes symmetrically provided on one side, and the threaded holes are adapted to the fixing bolts.

[0013] Preferably, each of the two outer shells has a folded edge on one of its opposite sides, and the folded edge has a fixing hole for easy fixing with bolts.

[0014] Preferably, sealing plates are installed at both ends of the valve body, and the sealing plates are located inside the outer shell.

[0015] Preferably, a sealing gasket is provided between the sealing plate and the pipe flanges on both sides.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. First, the flange is connected by the meshing of teeth and grooves, and then the outer shell is fixed by fixing bolts. When the bolts are loose, the meshing of teeth and grooves can prevent the flange from rotating randomly due to the loose bolts.

[0018] 2. The main body of the valve of this device is integrally formed with the pipeline. The flange is rotated and adjusted on the outside of the pipeline, which avoids leakage at the flange adjustment point due to long-term use.

[0019] 3. The outer casing of this device is a split design, which makes it easier and faster to replace flanges with different numbers of flange holes when needed, avoiding the need to replace the entire valve body and reducing costs. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figures 1-4. This utility model provides a technical solution: an easy-to-install regulating valve, including a valve body 1, two outer shells 2 symmetrically provided at the ends of the valve body 1, a flange portion 4 provided on one side of the two outer shells 2, and flange holes 11 evenly provided on the flange portion 4.

[0027] Both ends of the valve body 1 are equipped with fixing blocks 5. The outer side of the fixing blocks 5 is evenly provided with teeth 6, and the inner side of the two outer shells 2 is evenly provided with grooves 10 that are adapted to the teeth 6.

[0028] As shown in Figures 1 and 4: an arc-shaped groove 9 is provided on the other side of each of the two outer shells 2, and a fixing bolt 12 is provided inside the arc-shaped groove 9; with the above arrangement, when the two outer shells 2 rotate, the fixing bolt 12 can also be connected to the threaded hole 7, thereby fixing the position of the two outer shells 2 and preventing the outer shells 2 from becoming loose.

[0029] As shown in Figures 3 and 4: Two threaded holes 7 are symmetrically opened on one side of the fixing block 5. The threaded holes 7 are adapted to the fixing bolts 12. Through the above arrangement, the threaded holes 7 and the fixing bolts 12 cooperate with each other to restrict and fix the position of the two outer shells 2.

[0030] As shown in Figures 1, 2 and 4: each of the two outer shells 2 has a folded edge 3 on one side opposite to the other. The folded edge 3 has a fixing hole 8 for easy fixing with bolts. With the above settings, the folded edge 3 can make it easier to connect the two outer shells 2 together, making them a whole, which is convenient for moving, rotating and fixing.

[0031] As shown in Figures 2 and 3: both ends of the valve body 1 are equipped with sealing plates 13. The sealing plates 13 are located inside the outer shell 2. Sealing gaskets are provided between the sealing plates 13 and the pipe flanges on both sides. With the above arrangement, the sealing plates 13 will squeeze the sealing gaskets after contacting the pipe flanges, which facilitates the sealing work.

[0032] Working principle: First, remove the two fixing bolts 12 to free the outer shell 2 and move it backward, so that the groove 10 and teeth 6 on the inner side of the outer shell 2 separate. Then, according to the position of the holes on the flanges of the pipes on both sides, rotate the outer shell 2 to align the flange hole 11 with the hole. Then, push the outer shell 2 again to make the groove 10 and teeth 6 mesh with each other to restrict the position of the outer shell 2. Finally, tighten the fixing bolts 12 to complete the position fixing of the outer shell 2, thereby completing the adjustment of the position of the flange hole 11, so that the regulating valve can be more easily connected to the pipes on both sides.

[0033] Simultaneously, after moving the outer casing 2 backward, the bolts inside the fixing hole 8 can be unscrewed to separate the two outer casings 2. This makes it easier to replace the outer casing 2, and allows for replacement with outer casings 2 having different numbers of flange holes depending on the number of flange holes on the pipes on both sides, such as 4, 6, 8, or more flange holes. This facilitates adaptation to different pipe flanges.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
