Description

A connection device for glass steel pipes

technical field

The utility model relates to a pipeline connection device, in particular to a glass steel pipe connection device, which belongs to the field of pipeline connection devices.

Background technique

At present, the traditional fasteners connected to the ports of FRP pipes are hoop-type. One hoop body is a cylinder with threads on both sides of the inner wall. When connecting, the periphery of the pipe interface must be twisted. Although it can make the pipe interface firmly connected, But it is inconvenient to install, especially when there is a leak in the embedded pipeline and it is difficult to use when repairing or replacing a certain pipeline; the other pipe clamp is two semicircular bodies, and the radially outward extension pieces on both sides of the semicircular bodies are provided with bolt connection holes , the semicircle and the semicircle are fastened to the pipe joint by bolts. Although it is easy to install, its poor sealing will cause dripping at the pipe joint.

Utility model content

In order to solve the above problems, the utility model designs a connecting device for glass steel pipes, which has firm connection, good sealing performance, simple structure, convenient installation and use, and reduces costs.

The technical scheme of the utility model is:

A connecting device for glass steel pipes, comprising a connecting head, the connecting head is a ring barrel structure with inner and outer side walls, a connecting wall is arranged between the inner and outer side walls, and the pipe wall of the glass fiber reinforced plastic pipe is located on the Between the inner and outer side walls, a ring-shaped electric heating element is provided on both sides of the connecting wall; wherein, the inner end surface between the inner and outer side walls is an inclined surface, so that the connection between the glass fiber reinforced plastic pipe and the connecting head is tighter, Not easy to leak.

When in use, connect two FRP pipes to the two sides of the connector respectively, and then energize the two ends of the exposed electric heating element to realize thermal fusion, and the connection is fast and firm.

Further, the electric heating element is made of bent metal wire, and is provided with exposed ends, and heat fusion is realized by electrifying the two ends of the exposed electric heating element.

The utility model has the advantages of firm connection, good sealing performance, simple structure, convenient installation and use, and reduced cost.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

The preferred embodiments of the present utility model are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in Figure 1, a connection device for glass steel pipes includes a connection head 1, the connection head 1 is a ring barrel structure with inner and outer side walls, and a connecting wall 2 is arranged between the inner and outer side walls. The pipe wall of the glass fiber reinforced plastic pipe 3 is located between the inner and outer side walls, and an annular electric heating element 4 is provided on both sides of the connecting wall 2; The end, through the two ends of the exposed electric heating element to achieve thermal fusion, butt the FRP pipe and the connector, and then realize the thermal fusion by electrifying the two ends of the exposed electric heating element, the connection is fast and firm. Wherein, the inner end surface between the inner and outer side walls is an inclined surface, so that the connection between the glass fiber reinforced plastic pipe and the connecting head is tighter, and water leakage is not easy.
