Description

a socket joint

technical field

The utility model relates to a socket joint.

Background technique

Socket joints are generally used for the connection of pipelines. One end of the pipeline has a socket, and the other pipeline has a socket that matches it. The socket is inserted into the socket, and two sections are realized by fixing the socket on the socket. For the fixed connection of the pipeline, in order to meet the sealing requirements, a sealing ring is generally installed between the socket and the socket. The structure of the existing socket joints is generally relatively complicated, and there are many installation steps, and both the material cost and the labor cost are relatively high.

In view of this, the inventor specially developed a socket joint, which overcomes the above-mentioned defects, and this case arises from it.

Utility model content

The utility model provides a socket joint, which has good connection and sealing effects, simple structure, easy installation and low cost.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A socket joint, comprising a socket and a bell-shaped socket, the bell mouth of the bell-shaped socket faces the socket, and a sealing ring with a warped section is fixedly installed on the outer surface of the socket. The orientation of the bell sockets is the same, and the sealing ring is tightly pressed in the flare socket to realize fixation and sealing.

The thickness of the sealing ring decreases gradually from the root to the opening, and its inner surface and outer surface are both arc-shaped.

The above-mentioned sealing ring is fixed on the socket through the annular fiberglass.

Above-mentioned trumpet-shaped socket is made of fiberglass.

There are several sealing rings.

After adopting the above scheme, the trumpet-shaped socket of the utility model is very convenient for the insertion of the socket, and the installation can be completed only by inserting the socket into the trumpet-shaped socket, the installation is very simple, and the labor cost is effectively reduced; due to the warped sealing ring It has good elasticity, so when the sealing ring is tightly pressed in the bell-shaped socket, under the action of the elasticity of the sealing ring, the socket can be fixed on the bell-shaped socket, and has good sealing performance; due to the sealing ring The orientation of the warped opening is the same as that of the trumpet-shaped socket, so the resistance is small when the socket is inserted. On the contrary, when the external force causes the socket to protrude outward, the warped sealing ring will Reverse deformation will be performed, and the socket will be subject to great resistance, so the socket is not easy to loosen and has good connection performance; at the same time, the utility model has a simple structure and reduces the manufacturing cost.

Label description

Socket 1, bell-shaped socket 2, bell mouth 21, sealing ring 3, inner surface 31, outer surface 32, and ring-shaped glass fiber reinforced plastic 4.

Detailed ways

As shown in Figure 1-2, it is a socket joint disclosed by the utility model, which includes a socket 1 and a bell-shaped socket 2. The bell mouth 21 of the bell-shaped socket 2 faces the socket 1, and the outer surface of the socket 1 is fixedly installed with A sealing ring 3 with a warped cross-section, the orientation of the warped opening of the sealing ring 3 is the same as that of the bell-shaped socket 2, and the sealing ring 3 is tightly pressed in the bell-shaped socket 2 to realize fixing and sealing.

In this embodiment, the trumpet-shaped socket 2 can be installed on the pipe first, and the socket can be integrated with the pipe. The trumpet-shaped socket 2 is very convenient for the insertion of the socket 1. It is only necessary to insert the socket 1 into the trumpet-shaped socket 2. Complete the installation; since the warped sealing ring 3 has good elasticity, when the warped sealing ring 3 is tightly pressed into the horn-shaped socket 2, under the action of the elasticity of the warped sealing ring 3 , that is, the socket 1 can be fixed on the bell-shaped socket 2, and has good sealing performance; since the orientation of the warped opening of the sealing ring 3 is the same as that of the bell-shaped socket 2, it is subjected to pressure when the socket 1 is inserted. On the contrary, when the external force causes the socket 1 to have a tendency to come out, the warped sealing ring 3 will be reversely deformed, and the socket 1 will be subject to great resistance, so the socket 1 not easy to loose.

As shown in Figure 2, the thickness of the above-mentioned warped sealing ring 3 gradually decreases from the root to the opening, and its inner surface 31 and outer surface 32 are arc-shaped. This design can make the warped sealing ring 3 have a Better elasticity, more conducive to the insertion of the mouth, and better sealing performance with the socket.

FRP is a composite material that not only has the hardness, high temperature resistance, and corrosion resistance of glass, but also has the characteristics of being hard and unbreakable like steel. In order to avoid the iron products being easy to rust and other fixing methods with poor sealing performance, and to simplify the structure of the socket 1, the warped sealing ring 3 is fixed on the socket 1 through the ring-shaped glass fiber reinforced plastic 4, and the bell-shaped socket 2 is also Made of fiberglass. Because the tensile, bending and compressive strengths of general FRP can reach more than 400Mpa, the horn-shaped socket 2 made of it also has very good load-bearing performance, and it is not easy to deform when the long-term load-bearing pipeline is laid with coverings.

There can be multiple warped sealing rings 3 , the more the number, the better the fixed connection and sealing performance. In this embodiment, there are preferably two warped sealing rings 3 .

The above are only preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. All equivalent changes made according to the design idea of this case fall within the scope of protection of this case.
