Abstract
The invention relates to the field of corrugated pipes, in particular to a corrugated pipe. The corrugated pipe comprises a corrugated pipe body, wherein the corrugated pipe body comprises an inner plastic pipe, a middle metal pipe and an outer plastic pipe, the inner plastic pipe is connected with the middle metal pipe, the middle metal pipe is connected with the outer plastic pipe, one end of the corrugated pipe body is an opening end, the other end of the corrugated pipe body is a sealed end, the opening end is connected with a connecting pipe, a flange is connected to the end, far from the corrugated pipe body, of the connecting pipe, and a net cover is arranged at the outer part of the corrugated pipe body. Through the mode of wrapping the metal pipe between the two layers of plastic pipes, the corrugated pipe has the double properties of plastics and metal, thereby having higher strength and longer service life than a common all-plastics pipe. Besides, the traditional connecting mode of the flange and the corrugated pipe is changed, and the net cover structure is additionally arranged, so that the corrugated pipe has the advantages of being convenient to disassemble and mount, great in seal effect and high in wear resistance.

Summary of the invention
The object of the present invention is to provide the bellows that a kind of intensity is high, wear resistance is good, to solve multinomial defect of the prior art.
The technological scheme of technical solution problem of the present invention is: a kind of bellows, comprise bellows body, described bellows body comprises inner layer plastic tube, middle layer metal pipe and outer layer plastic tube, described inner layer plastic tube is connected with middle layer metal pipe, described middle layer metal pipe is connected with outer layer plastic tube, described bellows body one end is opening end, the other end is sealed end, described opening end is connected with adapter, described adapter is connected with flange away from one end of bellows body, described bellows body exterior is provided with net, during use, middle layer metal pipe is wrapped in centre by inner layer plastic tube and outer layer plastic tube, make it have the double grading of plastic tube and metal tube, if bellows occurs that damage needs repairing, adapter is separated with bellows body and keeps in repair respectively afterwards, without the need to all scrapping.
Preferably, described net is provided with hold-down ring.
Preferably, described inner layer plastic tube and outer layer plastic tube are equipped with protective coating.
Preferably, described net is nylon net.
Preferably, described flange is lap joint flange.
In employing, the beneficial effect of technological scheme is: a kind of bellows in the present invention, it is by the mode of parcel metal tube in the middle of two layers of plastic pipe, bellows is made to have the double grading of plastics and metal, than general pure plastic pipe, there is higher intensity and longer working life, and change the Placement of conventional flange and bellows and increase nets structure, bellows is had remove and install convenience, good sealing effect, advantage that wear resistance is high.Net is provided with hold-down ring; hold-down ring is used for net and bellows body are fitted tightly; inner layer plastic tube and outer layer plastic tube are equipped with protective coating; protective coating can corrosion protection, anti-aging; extend bellows working life; net is nylon net; nylon net is the same with plastic tube is insulator; cover on bellows and can not affect while bellows normally uses and can protect bellows; reduce the wearing and tearing of bellows; flange is lap joint flange, is used for bellows is connected with other original papers, removes and installs conveniently.
