PPR pipe connection accessory of high suitability

Technical Field

The utility model relates to a pipe connection accessory field, in particular to PPR pipe connection accessory of high suitability.

Background

PPR is short for tripropylene polyethylene, also called polypropylene random copolymer pipe, adopts a hot-melt mode, has special welding and cutting tools, has higher plasticity and is very economical in price. The external heat-insulating layer has better heat-insulating property, and the pipe wall is smooth without joints of the internal and external threads. Generally used for embedding walls or deep well embedded pipes. The PPR pipe has moderate price, stable performance, heat resistance, heat insulation, corrosion resistance, smooth inner wall, no scaling, safe and reliable pipeline system, no infiltration and service life of up to 50 years.

When connecting two sections pipelines, can use pipe connection spare such as double-pass pipe, three-way pipe, when using pipe connection spare, often can imbed metalwork such as copper inserts in the three-way pipe, two root canals say and utilize the screw thread on the copper inserts to connect. However, when the copper insert is used, one end of the copper insert needs to be inserted into the pipeline to be fixed with the pipeline, and when the copper insert is connected, the copper inserts with different specifications need to be used for pipelines with different specifications. Moreover, if the inner diameters of the two pipes are different during connection, for example, when the pipe with the small inner diameter is connected to the pipe with the large inner diameter, the copper inserts in the two pipes need to be not only adapted to the diameters of the copper inserts, but also fixed to the copper insert on the other pipe through threaded connection, and thus, a very large stock of the copper inserts is required. In view of the above problems, a solution is proposed as follows.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a PPR pipe connection accessory of high suitability, the connecting piece that has same specification can the pipeline of the multiple specification of adaptation to it is fixed to be connected with it, the advantage of the stock that significantly reduces.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a PPR pipe connection accessory of high suitability, includes internal connection post and external board, the internal connection post is cylindrically, the external board is circularly, the external board is located the one end of internal connection post, external board and internal connection post formula design as an organic whole, the interface channel has been seted up on the internal connection post, the interface channel runs through internal connection post and external board, the interface channel is used for circulating the object, the diameter of external board is greater than the diameter of internal connection post, the internal connection post is used for in the male connection pipe joint, and is connected with the coupling melting.

Preferably, the connecting channel comprises a connecting part and a flow channel part, the connecting part is located at one end, close to the outer connecting plate, of the connecting channel, a plurality of internal threads are fixedly arranged on the inner wall of the connecting part, and the internal threads are used for being connected with external threaded parts.

Preferably, the inner connecting column is provided with a buffer head, the buffer head is fixedly connected with the inner connecting column, and one end, far away from the inner connecting column, of the buffer head is provided with a chamfer.

Preferably, the outer connecting plate is provided with a caulking groove, the caulking groove surrounds the outer wall design of the inner connecting column, and the caulking groove is used for increasing the connection sealing performance of the inner connecting column and an external pipeline.

The beneficial effects of the utility model are that: when the hot melt connecting device is used, the internal connecting column is inserted into external pipe joints such as a three-way pipe, and the internal connecting column is fixedly connected with the three-way pipe in a hot melt mode. If the diameter of the internal connecting column is larger than the inner diameter of the three-way pipe, one end of the internal connecting column is abutted against one end of the three-way pipe without inserting, and hot melting is directly carried out. Because the three-way pipe and the internal column are both made of PPR materials, the three-way pipe and the internal column can be tightly combined after being heated and melted, and the joint can not leak. After the connecting pipe is completed, the external pipeline can be directly connected with the internal thread on the connecting part through the threaded part, and the connection between the external pipe fitting and the three-way pipe is completed.

The internal connecting column and the external connecting plate of one size can be connected with pipelines of various sizes, so that the applicability of the device is increased, and the stock of copper inserts can be greatly reduced.

Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. In which like parts are designated by like reference numerals. It should be noted that as used in the following description, the terms "front," "back," "left," "right," "upper," and "lower" refer to directions in the drawings, and the terms "bottom" and "top," "inner," and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in figures 1 and 2, the high-applicability PPR pipe connection fitting comprises an internal connection column 1 and an external connection plate 2.
