Description

Combined connection device for socket pipe

technical field

The utility model relates to a pipe connection, which is a combined connection device for socket pipes.

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 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, to provide a combined connection device for socket pipes, which can resist pressure, vibration, impact and other factors when the pipes are laid in special environments such as hillsides and rivers. Adverse effects, 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 combined connection device for socket pipes, which includes a pipe, one end of the pipe is provided with a socket, and the other end is provided with a socket, and the feature is: it also includes a flange and bolts, the sockets and sockets of the pipes are respectively sleeved with flanges and fixedly connected, the two pipes are placed opposite to the sockets and the sockets, and the sockets of the pipes are socketed on the sockets of the other pipe And fixed connection, the respective flanges of the two pipes are connected by bolts.

The outer surface of the pipe socket is sleeved with a sealing ring and sealed and fixedly connected.

The beneficial effect of the combined connection device for socket pipes of the utility model is: when the pipes laid in special environments such as hillsides and rivers are subjected to pressure, vibration, and impact, the socket connections in the socket openings can ensure the connection between the pipes. The socket connection does not cause radial displacement and misalignment, and the flange between the pipes is fixed by bolts to ensure that the axial displacement and cracking will not occur between the sockets, ensuring that the pipes, especially the joints of the pipes, are safe, stable and leak-free. When in use, first put the flanged pipe socket into the socket of another flanged pipe, and then pass the bolts through the flanges of the two pipes at the same time, and tighten them with nuts. That's it. 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 combined connection device of socket pipe of the present invention;

Fig. 2 is the structural representation of this embodiment.

In the figure: 1 socket, 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 combined connection device for a socket pipe, which includes a pipe, a socket 5 is provided at one end of the pipe, a socket 1 is provided at the other end, and a flange 3 and a bolt 4 are provided. The pipe The socket 5 and socket 1 of the flange 3 are respectively socketed and fixedly connected. The two pipes are placed opposite to the socket 5 and the socket 1, and the socket 5 of the pipe is socketed on the socket 1 of the other pipe. The flanges 3 on which the two pipes are respectively socketed are fixedly connected by bolts 4 . The outer surface of the socket 1 of the pipe is sleeved with a sealing ring 2 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 φ600㎜, two grooves are arranged on the socket 1, and O-rings 2 are built in the grooves, and four bolts 4 are used for fastening. orchid3. When in use, first put the pipe socket 1 provided with the flange 3 into the socket 5 of another pipe sleeved with the flange 3, and then pass the bolt 4 through the flanges 3 of the two pipes at the same time, It can be fastened by nut screw connection.

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.
