Description

PE supply pipe and linkage structure thereof

Technical field

The utility model belongs to plastic tube and makes the field, and relate in particular to a kind of steel mesh and strengthen the PE supply pipe, and the linkage structure that is connected of a plurality of supply pipe.

Background technique

Steel mesh strengthens the PE supply pipe; Realized adopting less plastic raw material to process high tenacity reinforced plastic pipe through in tube wall, burying steel wire underground; As a kind of novel tube; It bears pressure and is significantly improved, and the pure pipe of moulding of cost of production and uniform pressure grade is compared decline to some extent, and global advantage has obtained the market approval.But in the existing technology, still all adopt electric melting pipe fittings to connect because steel mesh strengthens the PE supply pipe, the phenomenon of pipe leakage is commonplace.Welding connects and has more shortcoming, at first, and during product export; Electric melting pipe fittings separates with the PE pipe, needs when install in the building site earlier the PE pipe to be inserted in the electric melting pipe fittings bellmouth, will have the inconsistent situation of PE pipe insertion depth like this; Energising is merged bad; Cause and leak, especially connect for bigbore PE pipe, the as easy as rolling off a log appearance distortion in PE pipe two ends causes welding the difficulty increase even can't weld; Then, welding requirements is high, needs special welding machine could produce desirable effect, and this pipe fitting bore that also just causes can welding in the existing technology is restricted; Secondly, the installation requirement of pipe fitting is high, needs special technician; At last, pipe fitting is installed because installation is consuming time oversize, also must when electricity is arranged, could install, and is therefore very high to environment requirement, also has potential safety hazard in the time of power consumption; At last, the welding position of PE pipe influences working life owing to all be plastics thereby in use produce distortion because of pressure easily even leak.

Summary of the invention

In order to solve above-mentioned technical problem; The purpose of the utility model provides a kind of PE supply pipe and linkage structure thereof; Its link position adopts steel ring typing also to connect through the plastic tube fitting, has that the pipeline connection is convenient, installation difficulty and advantages such as installation cost reduction, raising in working life.

In order to reach above-mentioned purpose, the technological scheme below the utility model has adopted:

A kind of PE supply pipe is embedded with one deck steel mesh at least in the tube wall, be embedded with steel ring respectively in the tube wall of body two ends interface position.

The utility model is owing to adopted above technological scheme; Adopt and to bury steel ring in the interface tube wall of two ends underground respectively to the support of finalizing the design of two end interfaces of supply pipe; Avoid mouth of pipe distortion round, can adopt the plastic tube fitting to connect two supply pipes and also can adopt seal ring to implement sealing between the two, very convenient when the pipeline connection like this; Do not need the professional workforce to operate Special Equipment; Greatly reduce installation difficulty and installation cost, reduced ground excavation and on-the-spot large-scale welding equipment, practiced thrift investment of heavy caliber pipe connection device and energy consumption; And the tubing shape keeps easily, can not be out of shape, and the steel mesh steel wire can improve 2 to 4 times of the abilities that tubing presses in anti-, and the interface steel ring can improve 2 to 5 times of the abilities of tubing critical external compressive resistance, can practice thrift a large amount of PE raw materials, improves working life greatly.

As preferably, said steel ring is fixedly connected with steel mesh.Like this, steel ring can be used for anchoring steel mesh steel wire, makes things convenient for the tubing manufacturing.Further preferred, said steel ring and steel mesh welding are fixing.

As preferably, said steel ring and body are one-body molded.The seamless combination that can guarantee steel ring and body like this with firmly be connected.

As preferably, said steel ring is a shaped steel.Not yielding so more.

As preferably, the tube wall exterior of said body is twined continuously and is covered the plastic-steel band.

A kind of PE supply pipe linkage structure; Comprise two aforesaid PE supply pipes; And plastic tube fitting; One end interface of first PE supply pipe inserts the interior seal ring sealing and fixing of also passing through of an end of plastic tube fitting, also passes through the seal ring sealing and fixing in the other end of the end interface insertion plastic tube fitting of second PE supply pipe.This technological scheme is because be embedded with steel ring in the interface position tube wall of supply pipe; Indeformable so can guarantee the mouth of pipe can bear bigger anti-pressure ability; Thereby can adopt the plastic tube fitting to be fixedly connected with seal ring; The pipeline connection is convenient, installation difficulty and installation cost reduce, not yieldingly leak, anti-pressure ability and improving greatly working life, and, can realize that the above large-caliber water supply pipe of 3m connects.In addition, this scheme metalwork all is embedded in plastics inner and does not contact with the external world, thus the water pollution of having avoided metal erosion to get rusty causing be connected inefficacy.This plastic tube fitting is not limited to the plastic straighttube form, can also be bend pipe, many siphunculus fitting or other pipe connector forms.

As preferably; One end of the one end interface insertion plastic tube fitting of said first PE supply pipe is interior and pass through at least two seal ring sealing and fixing, and the other end of the end interface insertion plastic tube fitting of second PE supply pipe is interior also through at least two seal ring sealing and fixing.It is convenient to close the water experiment after pipeline connects like this, only need between two seal rings, fetch water to press and just can confirm to close the regimen condition.
