Bellows refers to the tubular elastomeric sensing element connected into along folding retractable direction with collapsible wrinkle sheet.Bellows is widely used in instrument and apparatus, and predominant use is the measuring cell as pressure measuring instruments, pressure is converted to displacement or power, and bellows tube wall is thinner, and sensitivity is higher, and measuring range is that tens of handkerchief is to tens of MPa.Bellows mainly comprises metal bellows, corrugated flexible hose, plastic film capicitor etc., other material bellowss such as plastics are in medium transport, electric power threading, lathe, there is irreplaceable effect in the fields such as household electrical appliances, but the feature due to plastics itself makes plastic film capicitor, and concrete intensity is little, the shortcoming that wear resistance is low, as a kind of prestressing force plastic film capicitor that China Patent No. is CN204533885U, its technological scheme is: comprise plastic film capicitor, at the two ends of described plastic film capicitor, anchor plate socket is set, and be connected with anchor plate by described anchor plate socket, the outer ring of described anchor plate is provided with the first snap ring and the second snap ring, concrete pouring groove is formed between described first snap ring and the second snap ring, on the outer ring of described anchor plate socket, annular is provided with the first seal groove, the inner ring of described anchor plate is provided with the second seal groove, described first seal groove and the second seal groove match, sealing joint strip is combined with between described first seal groove and the second seal groove, the inside of described plastic film capicitor is provided with the stiffening rib of several rings, its benefit is: by arranging anchor plate socket and anchor plate at the two ends of plastic film capicitor, comparatively complete sealing is formed between anchor plate socket and anchor plate, spillage can be avoided, the technique of this device is simple simultaneously, ring stiffness is high, lightweight, reliable in quality, pliability is good, but it is low that the program does not solve plastic film capicitor intensity, the drawback worn no resistance.
Model utility content
The purpose of this utility model 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 the utility model technical solution problem 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 utility model, 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.
Accompanying drawing explanation
