The bearing pressure is less than 5MPa, so there is an urgent need for a connection structure with reliable connection, high working pressure and convenient construction and installation.

Utility model content

The technical problem to be solved by the utility model is to provide a welded ring pipe clamp to solve the technical problems of poor connection reliability and low working pressure of the existing pipeline connection structure.

In order to solve the above technical problems, the technical solution of the present invention is: a welded ring pipe clip, including an arc-shaped pipe clip body connected together by fasteners, the inner surface of the arc-shaped pipe clip body is provided with a The annular groove of the sealing ring, the pipe clip also includes two connecting rings, the connecting rings are used for fixed connection with the pipeline, and the connecting rings are arranged on the inner surface of the arc-shaped pipe clip body. In the connecting groove, the engaging groove is located on the butt joint side of the arc-shaped pipe clamp body.

As a further improvement, the connecting ring body is a steel ring.

As a further improvement, the locking groove is open to the inside.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

Since the inner surface of the arc-shaped tube clamp body is provided with a snap-in groove that matches the connecting ring body, the axial positioning of the arc-shaped tube clip body can be realized after the snap-in groove is snapped into the corresponding connecting ring body, forming a very High connection strength, withstand high pressure in the pipeline, simple structure, easy to disassemble, and use a special pressure-responsive sealing ring in the annular groove, and the sealing ring corresponds to the butt joint position of the two butt pipes, so that the internal pressure of the pipeline makes the sealing ring It is tightly attached to the pipeline to form a seal with high sealing reliability. The overall installation and construction are simple and fast, easy to maintain, and resistant to earthquakes and shrinkage and expansion.

Since the connecting ring body is a steel ring, it is economical, energy-saving, safe and hygienic.

Since the clamping groove is open to the inner side, it is convenient for processing and convenient for installation and use.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1 to 4, a welded ring pipe clip includes an arc-shaped pipe clip body 1 connected together by fasteners, and the inner surface of the arc-shaped pipe clip body 1 is provided with a sealing ring 4 The annular groove 3, the pipe clip also includes two connecting ring bodies 5, the connecting ring bodies 5 are used for fixed connection with the pipeline 6, the connecting ring bodies 5 are arranged in the clamping groove 2 on the inner surface of the arc-shaped pipe clip body 1, The clamping groove 2 is located on the abutting side of the arc-shaped tube clamp body 1 .

The above-mentioned connecting ring body 5 is a steel ring, which is economical, energy-saving, safe and hygienic, and the installation cost is about 30% lower than that of the flange connection.

The specific setting method of the connecting ring body 5 can be in accordance with the structural form of Fig. 3, that is, the connecting ring body 5 is fixed on the outer surface of the pipe end by welding, of course other fixing methods can also be used, the setting of the connecting ring body 5 At the same time, the strength of the pipeline 6 can be improved, and the structural design is simple and reasonable.

After the coupling groove 2 and the connecting ring body 5 are used to cooperate and connect, the axial positioning between the arc-shaped pipe clamp body 1 and the two pipes 6 can be realized, so as to realize the connection between the two pipes, and at the same time between the two clamping grooves 2 A special pressure-responsive sealing ring 4 is placed in the annular groove 3 between them, so that the sealing ring 4 corresponds to the butt joint of the two butted pipes 6, and the internal pressure of the pipe 6 is used to make the sealing ring tightly adhere to the pipe, thereby completing the sealing .

Wherein snap-in groove 2 also can be set to following concrete structure, is about to snap-in groove 2 is opened to the inside, only produces a groove edge during processing like this, is convenient to processing and installation.

As shown in Figure 4, the pipe clamp is used to connect two butt pipes. In Figure 4, three pipe clamps are used to connect the two butt pipes. In the specific operation, the pressure response sealing ring 4 is now socketed in it. One pipe end, then pass the other pipe end through the sealing ring 4, so that the sealing ring 4 is located between the two connecting rings 5, and corresponds to the connecting seam of the two butt pipes, and then the arc pipe clamps The clamping grooves 2 on the inner surface of the body 1 are respectively clamped on the corresponding connecting rings 5, and the sealing ring 4 is also correspondingly placed in the annular groove 3 on the inner surface of the arc-shaped tube clamp body 1, as shown in Figure 1, After the clamping groove 2 is clamped with the connecting ring body 5, the axial positioning of the arc-shaped tube clamp body 1 on the two butt pipes 6 is realized, so as to achieve the purpose of connecting the two butt pipes. At the same time, the sealing ring 4 and the two butt pipes 6 Corresponding to the butt joints of the pipe, the internal pressure of the pipe is tightly attached to the pipe to form a seal, and the other two pipe clips are also installed in the above-mentioned way, except that the three pipe clips share the above-mentioned sealed ring 4 that has been socketed. After the three pipe clips are installed respectively, just connect the two adjacent pipe clips through fastening bolts 7, so as to finally complete the connection of the two pipes. The whole operation process is simple, easy to operate, and the connection strength after connection Compared with other installation methods, it has the advantages of convenient and fast installation, reliable sealing, shock resistance, shrinkage and expansion resistance, etc.

The structure of the pipe clamp is simple and easy to disassemble. The structure of the pipe clamp allows a certain deflection angle and displacement after the pipeline is connected. Separation and leakage to ensure optimal sealing performance.

The specific construction is simple, which can shorten the construction period by one-third, the sealing reliability is high, and the maintenance is simple and convenient. The connection method of two clamping grooves increases the working pressure and solves the problem of pipeline connection in coal mines and chemical industries.
