Abstract

The utility model discloses a large-diameter PE plastic double-wall corrugated pipe double-socket connection structure, which comprises a split-type unit pipe and a double-socket connector, both ends of the unit pipe are socket structures, and the double-socket Both ends of the mouth connector are socket structures, and when the adjacent unit pipes are connected front and back, the double socket connectors are respectively connected with one end of the adjacent unit pipes. Using split-type unit pipes and double-socket connectors, since the production process of unit pipes is separated from the production of double-socket connectors, the process stability and production efficiency of the unit pipe parts are greatly improved, and the production line speed is increased year-on-year.

Description

Large Diameter PE Double-socket connection structure of plastic double-wall corrugated pipe

technical field

The utility model relates to the field of pipe materials, in particular to a double-socket connection structure for large-diameter PE plastic double-wall corrugated pipes.

Background technique

At present, the socket part of the PE double-wall corrugated pipe is mainly produced in two ways. One is to form the double-wall corrugated pipe forming machine on-line flaring, and the other is to make the corrugated pipe fittings by injection molding machine or mechanical processing. After post-processing, the socket fitting is connected to the corrugated pipe. The above two methods have their disadvantages. In the method of online production, the production speed of the pipe is limited by the forming speed of the socket, which reduces the overall production efficiency, and the strength of the flaring head produced on-line is low; the way of injection molding or mechanical processing is adopted. On the one hand, it is necessary to increase equipment investment. Due to the limitation of its processing method, the investment in socket equipment for processing pipes with a diameter exceeding 600mm (large-diameter PE plastic double-wall corrugated pipe) will be very large. On the other hand, its non-continuous production method, production The efficiency is low, the production cost is high, and the application requirements of the bellows cannot be met.

As mentioned above, in the production of PE double-wall corrugated pipes in the prior art, there are deficiencies in the production method of the socket, especially for large-diameter pipes, the production of the socket, and online processing have the disadvantages of low production efficiency and poor quality stability. Using injection molding or mechanical processing requires additional equipment investment, and single-piece processing is slow and costly, which cannot meet the application requirements of bellows. Therefore, it is necessary to develop a new large-diameter PE bellows. Socket connection structure.

Utility model content

In view of the above problems, the utility model provides a double-socket connection structure of large-diameter PE plastic double-wall corrugated pipes to solve the problems in the prior art.

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

The double-socket connection structure of large-diameter PE plastic double-wall corrugated pipe is characterized in that it includes a split-type unit pipe and a double-socket connector, both ends of the unit pipe are socket structures, and the double-socket connector Both ends of the pipe are socket structures, and when adjacent unit pipes are connected back and forth, the double socket connectors are respectively connected to one end of the adjacent unit pipes.

In a preferred embodiment of the present invention, an elastic rubber sealing ring is arranged between the double socket connector and the unit pipe.

The beneficial effects of the utility model are:

1. Adopt split-type unit pipes and double-socket connectors. Since the production process of unit pipes is separated from the production of double-socket connectors, the process stability and production efficiency of the unit pipe parts are greatly improved, and the production line speed is increased year-on-year. .

2. The production unit pipes and double-socket connectors use the same equipment and process flow. For corrugated pipe manufacturers, the production problems of the pipe connection parts can be solved without increasing investment.

3. The production cost and production efficiency of double-socket connectors are close to the production of pipes. Compared with injection molding and mechanical processing, the cost is greatly reduced, and there is no supporting problem caused by the difference in pipe diameter.

4. The double socket connector is separated from the unit pipe production process. Compared with the online flaring process, the socket part has more flexibility in raw material selection, structure and strength design, and the socket strength is improved. The socket part of any thickness can be produced according to the demand.

The features of the utility model can be clearly understood by referring to the drawings of this case and the detailed description of the following preferred embodiments.
