Description

Rubber short tube sleeve type connection structure

Technical Field

The utility model relates to the technical field of pipeline connection, in particular to a rubber short-tube sleeve type connection structure.

Background Art

At present, the more widely used pipe connection methods in engineering include threaded connection, flange connection, welding connection, groove connection, compression connection, socket connection and other connection methods. These connection methods have their own limitations in use. For example, some connection methods require that the pipe diameters of the connecting pipes must be the same, and the connection of pipes with different diameters needs to be achieved through standardized (pipe diameter conversion) fittings; some connection methods require that the pipe materials must be consistent, and pipes of different materials cannot be used.

In actual construction, if an existing pipeline is connected to a newly built pipeline, it will be very difficult to achieve a safe, fast and tight connection between the pipelines because the pipe materials, pipe diameter specifications, connection methods, etc. of the two pipelines may be different.

Utility Model Content

The utility model aims to provide a rubber short tube sleeve type connection structure to solve the problems raised in the above background technology.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber short-tube sleeve-type connection structure, comprising a pipe 1 and a pipe 2;

The outer walls of the pipe 1 and the pipe 2 are both sleeved with a belt-type rubber sealing ring;

The two belt-type rubber sealing rings are outer-connected with a same rubber short tube, both ends of the rubber short tube are sleeved with composite material clamps, and the two composite material clamps are respectively sleeved on the two belt-type rubber sealing rings.

Preferably, a roughened layer is provided at the connection between the pipe 1 and the pipe 2 and the belt-type rubber sealing ring.

By adopting the above technical solution, the contact area between the belt-type rubber sealing ring 2 and the outer wall of the pipe 1 and the pipe 2 is roughened so that the covering should be tightened firmly without loosening or slipping.

Preferably, the diameter of the belt-type rubber sealing ring is adapted to the outer diameters of pipe one and pipe two.

By adopting the above technical solution, the belt-type rubber sealing ring 2 should be tightly attached to the outer walls of the pipe 1 and the pipe 2 and should not be loose or slip.

Preferably, the rubber short tube is in close contact with the belt-type rubber sealing ring.

Preferably, the belt-type rubber sealing ring is arranged in multiple layers, and the number of layers of the belt-type rubber sealing ring can be determined according to the size of the gap between the outer walls of the pipes one and two and the inner wall of the rubber short tube.

Preferably, the composite material clamp comprises two semicircular hoop pieces, and screw holes are provided at both ends of the semicircular hoop pieces, and the same plastic bolt is installed in the inner threads of the two corresponding screw holes.

Compared with the prior art, the beneficial effects of the utility model are:

1. This scheme has relatively loose requirements on the pipe diameter of the connecting pipes, requiring only that the outer diameters of the pipes be the same or roughly similar. Compared with most traditional pipe connection methods that require the pipe diameters of the connecting pipes to be strictly the same, this scheme has a much wider scope of application, especially when connecting new pipes with existing pipes, the advantages are extremely obvious.

2. This solution has no requirements on the material of the connecting pipes (except for hoses).

3. The belt-type rubber sealing ring and short tube of this solution are made of rubber material, and the clamp is made of composite material, so there will be no problems such as rust. It can be installed indoors overhead, outdoors, or underground, and there are few restrictions on the use environment.

4. This solution consists of only three parts: a belt-type rubber sealing ring, a rubber short tube and a composite material clamp. It is easy to install and has low cost.

5. This solution uses rubber short tubes to connect the pipes on both sides. The length of the short tube is determined according to the distance between the pipe ports on both sides, which overcomes the disadvantage of fixed length of standard joints and fittings. This feature is also particularly suitable for connecting existing pipelines.

The utility model has the main function of sealing and water stopping, and the belt-type rubber sealing ring can also fill the gap between the pipeline and the short pipe by setting different numbers of sealing ring layers, thereby indirectly realizing the efficient connection of pipelines with different diameters; the composite material clamp has the advantages of being rust-proof and corrosion-resistant, so its application range is wider, and in addition to being used for indoor overhead pipeline connection, it can also be directly used for outdoor open-air or buried pipeline connection.
