Abstract

The utility model relates to a bidirectional socket-and-spigot joint of a steel skeleton plastic composite pipe, which comprises a pipe joint body, wherein socket-and-spigot holes are respectively arranged on two ends of a pipe joint, a locating slot used to socket-and-spigot pipes is arranged on the inner layer wall of the socket-and-spigot hole, a sealing ring good to connect the pipes is arranged on the inner of the socket-and-spigot hole. The bidirectional socket-and-spigot joint of the steel skeleton plastic composite pipe of the utility model has the following advantages in practical applications: (1) On production aspect: manufacturers producing pipes only need continuously produce straight pipes, and socket-and-spigot pipe joints are produced in addition, thereby improving working efficiency and saving production cost. (2) On transportation aspect: the pipes need to be socket-and-spigot are capable of respectively transporting the socket-and-spigot pipe joints and the straight pipes, thereby making transportation more convenient and rapid. (3) On field construction aspect: the length of the pipes is capable of being adjusted according to field needing, in particular to field rush repair, and the utility model has unexampled advantages.

Description

The two-way bell and spigot joint of steel skeleton plastic clad pipe

Technical field

The utility model relates to plastic pipe, particularly a kind of bidirectional socket pipe joint of steel skeleton plastic clad pipe.

Background technique

What generally use in plastic pipe at present is unidirectional bell-and-spigot pipe, promptly makes the socket joint hole in one in pipeline, only slightly deals with in the pipeline other end, to make things convenient for socket joint, with regard to causing pipeline big, a little problem, be difficult for the entrucking transportation like this, very inconvenient in transportation and making; When pipeline is longer, install also inconvenient in addition.

Summary of the invention

Task of the present utility model provides the two-way bell and spigot joint of a kind of steel skeleton plastic clad pipe, and it has solved existing unidirectional bell-and-spigot pipe socket joint and has installed inconvenient and be not easy to the problem of transporting and making.

The technical solution of the utility model is as follows:

The two-way bell and spigot joint of a kind of steel skeleton plastic clad pipe, it comprises the pipe joint body, two of described pipe joint is provided with the socket joint hole respectively, is provided with the locating slot of socket joint pipeline on the inner layer wall in socket joint hole, is equipped with in the inboard in socket joint hole to be beneficial to the seal ring that pipeline connects.

The two-way bell and spigot joint of steel skeleton plastic clad pipe of the present utility model is at its two the socket joint hole to be set, and bell-and-spigot pipe joint and pipeline are divided into two parts, has following advantage in actual applications:

1. aspect production: the producer that produces pipeline only needs to produce straight tube continuously, and the bell-and-spigot pipe joint is produced in regeneration in addition, has improved working efficiency thus, has saved cost of production.

2. aspect transportation: for the pipeline that needs socket joint, bell-and-spigot pipe joint and straight tube can be transported respectively, can make transportation convenient, quick like this.

3. construction aspect at the scene: can adjust duct length according to on-the-spot needs,, have more incomparable advantage especially for scene rush to repair.

The two-way bell and spigot joint of steel skeleton plastic clad pipe of the present utility model can be made by four kinds of materials such as enhancement mode SRPE (SPE), glass fibre reinforced plastics (FRP), steel plastics lined pipe and stainless steels.

Description of drawings

Accompanying drawing is the structural representation of the two-way bell and spigot joint of a kind of steel skeleton plastic clad pipe of the present utility model.

Embodiment

Referring to accompanying drawing, pipe joint body 1 is equipped with in the two-way bell and spigot joint of a kind of steel skeleton plastic clad pipe of the present utility model, at two of pipe joint socket joint hole 2 is set respectively, promptly two-way socket joint hole 2.On the inner layer wall in socket joint hole 2, be provided with the locating slot 3 of socket joint pipeline, be beneficial to the seal ring 4 that pipeline connects in the installing of the inboard in socket joint hole 2.

As shown in the drawing, the median pore radius of pipe joint is an internal diameter of the pipeline, and the socket joint aperture is an outer diameter tube, and seal ring 4 is equipped with in the both sides of pipe joint, in the inside of pipe joint locating slot 3 is set, and connects in order to reinforce socket joint.

Claims

1. two-way bell and spigot joint of steel skeleton plastic clad pipe, it comprises the pipe joint body, it is characterized in that, two of described pipe joint is provided with the socket joint hole respectively, on the inner layer wall in socket joint hole, be provided with the locating slot of socket joint pipeline, be equipped with in the inboard in socket joint hole and be beneficial to the seal ring that pipeline connects.
