Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve with an interface reinforcement structure. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. During operation, valves require a connecting pipe to be installed at their end via a flange for media transport. However, currently, most flange connections between valves and connecting pipes are directly bolted without any reinforcement structure. When the bolts loosen, media leakage can occur. Utility Model Content

[0003] The purpose of this invention is to provide a valve with an interface reinforcement structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a valve with an interface reinforcement structure, comprising a valve body, connecting pipes symmetrically arranged at both ends of the valve body, a first flange at both ends of the valve body, a second flange at the end of the connecting pipe near the valve body, a reinforcement ring movably fitted on the outer wall of the first flange and the second flange at adjacent positions, and an installation groove provided on one side of the reinforcement ring, the inner diameter of the installation groove being the same as the outer diameter of the first flange and the second flange.

[0005] Preferably, a plurality of lead screws are rotatably inserted at equal intervals on the side wall of the outer circle of the reinforcing ring, and a reinforcing rivet is threaded onto the rod wall of the lead screw extending into the mounting groove. A corresponding travel groove is provided on the inner wall of the mounting groove corresponding to the reinforcing rivet. The reinforcing rivet is slidably inserted into the inside of the travel groove, and a corresponding rivet matching groove is provided on the outer wall of the connection between the first flange and the second flange corresponding to the reinforcing rivet.

[0006] Preferably, a plurality of bolts are inserted through the first flange at equal intervals on the side away from the second flange, and a nut is threaded onto one end of each bolt that passes through the second flange.

[0007] Preferably, the inner diameter of the reinforcing ring is smaller than the outer diameter of the first flange and the second flange, but larger than the outer diameter of the connecting pipe.

[0008] Preferably, a lever block is fixedly connected to the rod wall at the end of the lead screw away from the reinforcing rivet block.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the valve structure with interface reinforcement structure of this utility model is simple and easy to use. By setting a reinforcement ring at the connection of the flange, the reinforcement rivet in the stroke groove inside the reinforcement ring can extend into the inside of the rivet adapter groove under the drive of the screw. The reinforcement rivet inserted into the rivet adapter groove can reinforce the connection between the two flanges, which can effectively avoid the problem of loosening of the connection between the flanges due to loose bolts.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5This utility model provides a technical solution: a valve with an interface reinforcement structure, including a valve body 1, with connecting pipes 2 symmetrically arranged at both ends of the valve body 1, and first flanges 3 arranged at both ends of the valve body 1. A second flange 4 is arranged at the end of the connecting pipe 2 near the valve body 1. A reinforcing ring 7 is movably sleeved on the outer wall of the first flange 3 and the second flange 4 at an adjacent position. An installation groove 8 is opened on one side of the reinforcing ring 7, and the inner diameter of the installation groove 8 is the same as the outer diameter of the first flange 3 and the second flange 4.

[0018] Several lead screws 9 are rotatably inserted at equal intervals on the side wall of the outer circle of the reinforcing ring 7. The lead screws 9 extend into the rod wall inside the mounting groove 8 and are threaded with reinforcing rivet blocks 11. The inner wall of the mounting groove 8 is provided with a corresponding travel groove 12 corresponding to the reinforcing rivet blocks 11. The reinforcing rivet blocks 11 are slidably inserted into the inside of the travel groove 12. The outer wall of the connection between the first flange 3 and the second flange 4 is provided with a corresponding rivet block matching groove 13 corresponding to the reinforcing rivet blocks 11. A toggle block 10 is fixedly connected to the rod wall of the lead screw 9 away from the reinforcing rivet blocks 11. The setting of the toggle block 10 can effectively make the lead screw 9 more convenient and effortless to rotate.

[0019] Several bolts 5 are inserted at equal intervals on the side of the first flange 3 away from the second flange 4, and a nut 6 is threaded onto one end of the bolt 5 that passes through the second flange 4. The bolts 5 and the nut 6 connect the first flange 3 and the second flange 4, which makes it easier to disassemble and assemble the connecting pipe 2.

[0020] The inner diameter of the reinforcing ring 7 is smaller than the outer diameter of the first flange 3 and the second flange 4, but larger than the outer diameter of the connecting pipe 2, so that the mounting groove 8 inside the reinforcing ring 7 can limit the connection between the flanges forming the ladder.

[0021] Specifically, when using this utility model, firstly, the reinforcing ring 7 is fitted onto the connecting pipe 2. Then, the first flange 3 and the second flange 4 are connected and locked using bolts 5 and nuts 6. The reinforcing ring 7 is moved to the connection between the first flange 3 and the second flange 4. First, a screw 9 is turned so that when the screw 9 rotates, it drives the reinforcing rivet 11 to extend along the stroke groove 12 toward the interior of the mounting groove 8, so that the reinforcing rivet 11 is inserted into the interior of the rivet adapter groove 13. Then, multiple screws 9 are turned one by one so that the reinforcing rivet 11 is inserted into the corresponding rivet adapter groove 13. The reinforcing rivet 11 can reinforce the connection between the two flanges, which can effectively avoid the problem of loosening of the connection between the flanges due to the loosening of the bolts 5. The valve body 1 can be any valve that needs to be connected to the pipeline using a flange.

[0022] 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.
