Abstract
The invention discloses a novel corrugated tube which comprises a corrugated tube body and a connector, wherein the corrugated tube body comprises an outer wall, a reinforcing layer and an inner wall; the reinforcing layer is positioned between the outer wall and the inner wall; a threaded tube is arranged at each of the two end openings of the corrugated tube body; one end of each of the threaded tubes is fixed with the corresponding end opening of the corrugated tube body in a welding manner; an annular groove vertical to the axis of the connector is formed in the middle position of the connector; a sealing ring for fixing the corrugated tube is arranged in the annular groove; inner threads that are matched with the threaded tubes are arranged in the two end openings of the connector. The novel corrugated tube provided by the invention has the benefits as follows: the threaded tubes are arranged at the two ends of the corrugated tube body, and each of the threaded tubes is matched with the thread in the end opening of the corresponding end of the connector, therefore the mounting process is simple, convenient and labor-saving, and at the same time a good sealing property is ensured by the sealing ring in contact with the corrugated tube body, and besides, as the reinforcing layer is arranged between the outer wall and the inner wall of the corrugated tube body, deformation is not easily caused during long-term use of the corrugated tube.
Description
Technical field
The present invention relates to pipe running tool field, particularly a kind of New corrugated pipe.
Background technique
Bellows only has the tubular elastomeric sensing element connected into along folding retractable direction with collapsible wrinkle sheet, is the housing of the cylinder-shaped thin wall wrinkle with multiple transverse wave.Bellows is widely used in instrument and apparatus, and predominant use is that seal section is in free state for opening is fixed, and utilizes auxiliary helical spring or reed to increase elasticity.Extend along tube length direction under the effect of internal pressure during work, make movable end produce the displacement becoming certain relation with pressure.Movable end drives pointer to get final product the size of direct indicated pressure.Bellows can be divided into metal bellows, nonmetal bellows by material; Individual layer and multilayer is divided into by structure.
Metal bellows is mainly used in the effects such as compensation pipes thermal distortion, damping, absorption pipe settlement, is widely used in the industries such as petrochemical industry, instrument, space flight, chemical industry.Other material bellowss such as plastics have irreplaceable effect in fields such as medium transport, ionization threading, lathe, household electrical appliances.But easily occur distortion when bellows is subject to excessive pressure at present, and bellows is in connection procedure, due to the most more complicated of joint structure, high cost, be unfavorable for installing, the process of simultaneously installing also compares to waste time and energy, and causes the waste that the aspects such as human and material resources are unnecessary.
Summary of the invention
Technical problem to be solved by this invention is to provide one and connects simply, installs simple and on-deformable New corrugated pipe, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technological scheme: a kind of bellows, comprise bellows main body and joint, described bellows main body comprises outer wall, back-up coat and inwall, described back-up coat is between outer wall and inwall, two ports of described bellows main body are provided with threaded pipe, one end of described threaded pipe and the port of bellows main body are welded and fixed, the intermediate portion of described joint is provided with the circular groove of its axis vertical, the seal ring for fixing bellows is provided with in described circular groove, the internal thread matched with threaded pipe is provided with in the two-port of described joint.
Preferably, the thickness of described back-up coat is less than the thickness of bellows outer wall.
Preferably, the aperture of the aperture major thread pipe of described joint.
Preferably, the internal diameter of described joint and the aperture of threaded pipe match.
Preferably, the both sides of described seal ring are provided with the concave station matched with threaded pipe pipe thickness.
The beneficial effect of above technological scheme is adopted to be: benefit effect of the present invention is that the two ends of bellows main body are provided with threaded pipe, match with the screw thread in one end port of joint, installation process is easy to be laborsaving, ensure that good sealing with the seal ring of bellows body contact simultaneously; Between the outer wall and inwall of bellows main body, be provided with back-up coat, make bellows not yielding in Long-Time Service process.
Accompanying drawing explanation

Fig. 2 is the structural representation of joint of the present invention.
Wherein, 1-bellows main body, 2-threaded pipe, 3-circular groove, 4-joint, 5-seal ring, 6-outer wall, 7-back-up coat, 8-inwall
Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 illustrates the specific embodiment of the present invention: a kind of New corrugated pipe of the present invention, comprise bellows main body 1 and joint 4, described bellows main body 1 comprises outer wall 1, back-up coat 7 and ripple inwall 8, described back-up coat 7 is between outer wall 6 and inwall 8, two ports of described bellows main body 1 are provided with threaded pipe 2, one end of described threaded pipe 2 and the port of bellows main body 1 are welded and fixed, the intermediate portion of described joint 4 is provided with the circular groove 3 of its axis vertical, the seal ring 5 for fixing bellows is provided with in described circular groove 3, the internal thread matched with threaded pipe 2 is provided with in the two-port of described joint 4, the thickness of described back-up coat 7 is 2-5cm, the aperture of the aperture major thread pipe 2 of described joint 4, the internal diameter of described joint 4 and the aperture of threaded pipe 2 match, the both sides of described seal ring 5 are provided with the concave station matched with threaded pipe 2 pipe thickness.
In reality of the present invention uses, first the bellows being threaded port is inserted into one end of joint 4, until stop when touching the seal ring 5 in circular groove 3 inserting, then another bellows is screwed in the other end of joint, owing to seal ring 5 being provided with the concave station suitable with bellows pipe thickness, thus bellows and joint 3 are tightly connected, also ensure that sealing good between bellows and joint 3.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
