Abstract

The utility model relates to a pressure-resistant high-strength plastic pipe fitting, which belongs to a pipe fitting, which is used in a plastic pipeline. The pressure-resistant high-strength plastic pipe fitting mainly comprises a connecting sleeve tube, an elbow, a three way, a four way, a return elbow, a sealing head, a size head, the tube mouth of the elbow, and a slantways connected tube mouth. The utility model is characterized in that the both ends of the pressure-resistant high-strength plastic pipe fitting are provided with straight line segments; an inserting mouth is arranged among the straight line segments; the internal diameter of the inserting mouth is slightly greater than the external diameter of the tube, the both ends of which are connected with the inserting mouth; the tubes on the both ends can be inserted into the inserting mouth, and an adhesive layer is clamped between the external wall of the tube in the inserting segment and the internal wall of the inserting mouth of the pipe fitting. The utility model has the advantages that the pressure-resistant high-strength plastic pipe fitting has very high bearing capacity and has favorable anticorrosion property; the adhesion is firm; the resource is abundant; the cost is low; the manufacture is easy; the usage is convenient, and the pipe fitting is clean and beautiful.

Description

Pressure-resistant high-strength plastic pipe piece

The utility model belongs to a kind of pipe joint, particularly in a kind of high pressure resistant highstrenghtpiston's pipe joint.

The existing pipeline that is widely used in building and the municipal engineering mainly is steel, iron pipe conduit and concrete duct.Such pipeline, not only investment is big, and transportation and install very difficult.The long-term use of steel, iron pipe conduit also exists the hidden danger of corrosion failure.At present, underground water pipe in many cities and gas pipe line etc. are because the long-term corrosion failure that causes that uses not only causes very big economic loss, but also causes bigger personal injury.

In some industry, though adopt plastic pipe as existing in the chemical engineering industry, because the thoroughly solution as yet of its connecting means or link, thereby can not effectively utilize, often leave hidden danger to keeping the safety in production.

The purpose of this utility model is to solve problems of the prior art, proposes a kind of connection pipe fitting of high pressure resistant High strength plastic pipe.

High pressure resistant highstrenghtpiston's pipe fitting of the present utility model, it mainly comprises adapter sleeve, elbow, threeway, four-way, return bend, end socket, CONCENTRIC REDUCER, elbow ozzle and mitered ozzle, there is straightway at the two ends that it is characterized in that described pipe fitting, and be provided with joint socket therein, its internal diameter is slightly larger than the external diameter of the pipe that two ends are attached thereto, the pipe at two ends can be inserted wherein, accompany bonding layer between the inwall of tube outer wall in this inserting section and pipe fitting joint socket.Described pipe fitting is isometrical link or reducing link.Described pipe fitting is concentric link or eccentric connector.Described elbow is the major diameter elbow, minor axis elbow or reducing elbow.Described threeway is three-dimensional threeway, double sweep tee or skew T.The chemical component of described high pressure resistant high-strength pipe is respectively 30-60% carbon fiber and 40-70% pottery by its weight.The chemical component of described high pressure resistant high-strength pipe is respectively the 60-80% PVC by its weight, 5-15% graphite and 15-25% glass fibre or carbon fiber.The chemical component of described high pressure resistant high-strength pipe is respectively the 55-75% polypropylene by its weight, 4-16% red soil or industrial residu and 20-30% carbon fiber or glass fibre.The chemical component that is described high pressure resistant high-strength pipe is respectively 60-75% vinyl benzene by its weight, white carbon black of 3-10% or French chalk and 20-30% glass fibre or carbon fiber.

The major advantage of high pressure resistant highstrenghtpiston's pipe fitting of the present utility model is that it has high bearing capacity, has good Corrosion Protection again, and is bonding firm, and aboundresources is with low cost, easy to manufacture, easy to use, and neat and artistic.

For being connected of the structure that further specifies high pressure resistant highstrenghtpiston's pipeline spare of the present utility model and profile and high pressure resistant High strength plastic pipe, be described with embodiment with reference to the accompanying drawings, its accompanying drawing has:

Fig. 1,2 is respectively the perspective and the sectional view of the adapter sleeve in the pipe fitting of the present utility model;

Fig. 3,4 is respectively the elbow at this pipe fitting middle part and the plan view of return bend;

Fig. 5,6,7 is respectively the end socket in this pipe fitting, the plan view of concentric reducer and eccentric reducer;

Fig. 8,9,10,11 is respectively the plan view of skew T, threeway, four-way and the threeway of Y shape;

Figure 12,13 is respectively the plan view of three-dimensional four-way and three-dimensional threeway.

In Fig. 1-3: 1,2 be respectively the High strength plastic pipe that is connected with pipe fitting two two ends, 3 is adapter sleeve, and 4 is bonding layer, 5 is elbow, and 6 is joint socket, and 7 is return bend, 8 is end socket, and 9 is the concentric reducer, and 10 is eccentric reducer, 11 is skew T, and 12 are threeway, and 13 is four-way, 14 is the threeway of Y shape, 15 is three-dimensional four-way or the threeway of band side outlet, and 16 is three-dimensional threeway or band side outlet elbow, and L is the length of the straightway at pipe fitting two ends.

Embodiment:

A kind of 90 ° of elbows 5 as shown in Figure 3 are provided with joint socket 6 at its two ends, and its length of straigh line L will peg graft with the High strength plastic pipe that is connected, and bond together mutually with tackiness agent, the PVC of elbow 5 usefulness 70%, 10% graphite, compound molded the forming of 20% glass fibre.
