Bellows elastic sensor connected with foldable ripples along the direction of folding expansion. Bellows are widely used in instrumentation, the main purpose is as a pressure detector measuring element, the pressure into displacement or force, the following understanding of the preparation method and process of armored bellows.
Armoured bellows have at both ends with anchor plate is inserted into the mouth, with anchor plate connected by the anchor plate is inserted into the mouth of plastic corrugated pipe, anchor plate of the outer ring is equipped with a retaining ring and second ring, for a retaining ring and second ring anchor plate is inserted into the mouth of the outer ring to set a seal on the groove, anchor plate on the inner ring of setting a second seal groove, make a seal groove and the second alignment of seal groove. A seal groove and the second seal groove alignment between the sealing rubber strip, the interior of the plastic corrugated pipe set with multiple seal groove: on both ends of plastic corrugated pipe is equipped with the anchor plate is inserted into the mouth and the anchoring plate, between anchor plate is inserted into the mouth and the anchoring plate form a relatively complete seal, can avoid the slurry leakage, at the same time the device has the advantages of simple process, high ring stiffness, light weight
To solve many of the defects of the existing technology, high strength and good wear resistance bellows are provided.
The solution is: Corrugated pipe, connected by the inside of the plastic pipe, middle tube and outer plastic corrugated pipe main body, inner plastic and outer plastic tube, the middle metal tube and the outer plastic corrugated pipe body side as an open end, the other side for sealing side, the joint connection in the open end, joint from one end of the corrugated pipe body have flange connection, corrugated pipe main body external set net, In use, when the inner vinyl pipe and outer vinyl pipe bellows are damaged and need to be maintained, just separate the pipe and the bellows and maintain them separately, without scrapping all the pipes.
The beneficial effects of adopting the above technical solutions for armored bellows are: Corrugated pipe is a metal tube with double plastic pipe, the corrugated pipe has a dual characteristic of plastic and metal, than ordinary pure plastic pipe has higher strength and longer life, but also changed the traditional way flange connection with bellows, increases the space truss structure, is convenient for corrugated tube disassembly, good sealing effect and the advantages of high resistance to wear. The net cover is provided with a pressing ring, the pressing ring is used to make the net cover and the bellows body close contact, the inner plastic pipe and the outer plastic pipe is provided with a protective coating. Protective coating helps to prevent corrosion, aging, and extend the life of bellows. The mesh cover is a nylon mesh cover. The nylon mesh cover is an insulator like the plastic tube. It can protect the bellows from normal use and reduce the wear of the bellows. The flange is loose sleeve flange, and the bellows are connected with other parts, disassembly and installation are convenient. The beneficial effects of adopting the above technical solutions are: Root utility model with the method of double metal pipe plastic pipe between package, make corrugated pipe has a dual characteristic of plastic and metal, than ordinary pure plastic pipe has higher strength and longer life, but also changed the traditional way flange connection with bellows, increases the space truss structure, is convenient for corrugated tube remove installation, good sealing effect and the advantages of high resistance to wear.
