Description

Connection device for double socket pipe

technical field

The utility model relates to pipeline connection, which is a connection device for pipes with double sockets.

Background technique

Pipeline transportation is a long-distance transport method of transporting liquid and gas materials using pipelines as a means of transportation. Transportation has the advantages of less energy consumption, low cost and good benefits. The pipe is the main component of the pipeline. According to the material, there are several types of pipes, such as steel pipes, cast iron pipes, reinforced concrete pipes, and non-metallic pipes. The connection methods include socket connections, flange connections, welding, and bonding. The socket connections are pipes. The connection method is convenient, fast, safe and efficient. The problem is that when the steel pipe is laid in special environments such as hillsides and rivers, the socket connection is easily cracked under the influence of pressure, vibration, impact and other factors. Leakage occurs.

Utility model content

The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a connecting device for pipes with double sockets, which can resist the adverse effects of pressure, vibration, impact and other factors when the pipes are laid in special environments such as hillsides and rivers , to ensure that the pipes, especially the joints of the pipes, are safe, stable and leak-free.

The solution to the technical problem of the utility model is: a connecting device for pipes with double sockets, which includes pipes, and the ends of the pipes are provided with sockets. The above-mentioned flange is socketed on the pipe, and the outside of the socket is fixedly connected. The two pipes are placed in the opposite position of the socket, and the ferrule is installed in the opposite socket of the two pipes. The flanges are fixed by bolts.

Sealing rings are sleeved in the sockets of the two pipes opposite to each other and on the outer surface of the ferrule, and sealed and fixedly connected.

The beneficial effect of the utility model double-socket pipe connection device is: when the pipes laid in the special environment of hillsides and rivers are subjected to pressure, vibration, and impact, the ferrule in the double-socket can ensure the double-socket connection between the pipes There is no radial displacement and misalignment, and the flange between the pipes is fixed by bolts to ensure that there is no axial displacement between the double sockets and cracks, ensuring that the pipes, especially the joints of the pipes, are safe, stable and leak-free. When in use, first insert the ferrule into the socket of the pipe with the flange, then insert the socket of another pipe with the flange on the ferrule, and then pass the bolt through the two pipes at the same time The flange of the flange can be fastened with nut threaded connection. The invention has the advantages of simple structure, practical and convenient, low cost and remarkable effect.

Description of drawings

Fig. 1 is the structural representation of the connecting device of the utility model double socket pipe;

Fig. 2 is the structural representation of this embodiment.

In the figure: 1 ferrule, 2 sealing ring, 3 flange, 4 bolt, 5 socket, 6 inner lining.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1, a connection device for a double-socket pipe, which includes a pipe, the end of the pipe is provided with a socket 5, and also includes a flange 3, a ferrule 1, and a bolt 4, and the flange 3 is socketed On the pipe, the outer side of the socket 5 is fixedly connected, the two pipes are placed in the opposite position of the socket 5, the ferrule 1 is installed in the socket 5 opposite to the two pipes, and the two pipes are respectively socketed The flange 3 is fixedly connected by bolt 4. The sealing ring 2 is sleeved on the inner surface of the socket 5 of the two pipes opposite to the outer surface of the ferrule 1 and sealed and fixedly connected. The utility model adopts prior art to manufacture, and bolt 4, nut are commercially available products of prior art.

Referring to Figure 2, this embodiment adopts a composite pipe with an inner lining 6, the diameter of the pipe is φ500㎜, four grooves are arranged on the outer surface of the ferrule 1, and O-rings 2 are built in the grooves, and four bolts 4 are used. Fasten the flange 3. When in use, first insert the ferrule 1 into the pipe socket 5 sleeved with the flange 3, then socket the socket 5 of another pipe sleeved with the flange 3 on the ferrule 1, and then insert the bolt 4 Pass through the flanges 3 of the two pipes at the same time, and fasten them with nut thread connections.

The utility model is not limited to this specific embodiment, and for those skilled in the art, simple duplication and improvement without creative work all belong to the protection scope of the claims of the utility model.
