Abstract
The invention relates to the technical field of corrugated pipes, in particular to a corrugated pipe. The corrugated pipe comprises a corrugated pipe body, and the two ends of the corrugated pipe body are provided with a left port and a right port. The corrugated pipe is characterized in that the left end and the right end of the corrugated pipe body have the same diameter, the diameter of the corrugated pipe body sequentially increases from two sides to middle, the outer surface of the corrugated pipe body is provided with waves which each have an acute-triangle-shaped section, a smooth transition portion is arranged between every two adjacent acute-triangle-shaped waves, an arc-shaped boss is arranged on each smooth transition portion, a fixed flange is welded to the pipe opening of the left port, the pipe opening of the right port is provided with a protrusion formed by compressing three waves, a sealing ring is welded to the right port, and a movable flange is arranged between the protrusion and the sealing ring. The corrugated pipe is good in sealing effect, high in strength and convenient to install.
Description
Technical field
The present invention relates to Bellows Technology field, be specifically related to a kind of bellows.
Background technique
Bellows has characteristic bending arbitrarily, that the fluid such as various liquid or gas carries out one of critical piping carrying connection, it is widely used in the water supply, draining, blowdown, exhaust, ventilation etc. of the such as various occasion such as Dish washing machine, air conditioner, bathhouse, water heater, medical equipment, when applying bellows, require that bellows has good intensity, and easy for installation.
Summary of the invention
For the problems referred to above, the invention provides a kind of good sealing effect, intensity is high, bellows easy for installation.Realize technological scheme of the present invention
Bellows, comprise bellows body, bellows body two ends are provided with left end interface and right-hand member interface, two ends, described bellows body left and right diameter is identical, described bellows body diameter is increased progressively to centre successively by both sides, bellows body outer surface is provided with the wave that cross section is acute triangle, even transition is provided with between described several acute triangle waves every, described even transition is provided with circular arc burr, the described left end interface mouth of pipe is welded with fastening flange, the right-hand member interface mouth of pipe is provided with the projection of three wave pressure contractings, right-hand member interface end is welded with seal ring, loose flange is provided with between projection and seal ring.
Described bellows body and left and right end interface are formed in one.
Adopt such scheme, because bellows body diameter is increased progressively to centre successively by both sides, facilitate the installation of flange plate, bellows body outer surface is provided with the wave that cross section is acute triangle, automatically a kind of stiffening rib of stealth is defined on the one hand when managing shaping, the intensity of bellows can be improved, span on the other hand between acute triangle ripple inner groovy and the degree of depth greatly reduce, also too much ponding can be avoided, water blocking phenomenon can not be caused, even transition is provided with between several acute triangle waves every, even transition is provided with circular arc burr, distortion greatly can be born be unlikely to damage, add the bending properties of bellows simultaneously, better adaptation surrounding environment.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
In figure, 1 is left end interface, and 2 is right-hand member interface, and 3 is bellows body, and 4 is wave, and 5 is transition part, and 6 is burr, and 7 is fastening flange, and 8 is protruding, and 9 is seal ring, and 10 is loose flange.
Embodiment
As shown in the figure, bellows, comprise bellows body 3, bellows body 3 two ends are provided with left end interface 1 and right-hand member interface 2, bellows body 3 and left and right end interface are formed in one, convenient for production, these 3 bodies of bellows and left and right end interface are fixed together, bellows body about 3 two ends diameter is identical, bellows body 3 diameter is increased progressively to centre successively by both sides, facilitate the installation of bellows flange plate, bellows body 3 outer surface is provided with the wave 4 that cross section is acute triangle, automatically a kind of stiffening rib of stealth is defined on the one hand when managing shaping, the intensity of bellows can be improved, span on the other hand between acute triangle wave 4 inner groovy and the degree of depth greatly reduce, also too much ponding can be avoided, water blocking phenomenon can not be caused, owing to being provided with even transition 5 between several acute triangle waves 4 every, seamlessly transit 5 and be provided with circular arc burr 6, distortion greatly can be born be unlikely to damage, add the bending properties of bellows simultaneously, better adaptation surrounding environment, left end interface 1 mouth of pipe is welded with fastening flange 7, right-hand member interface 2 end is welded with seal ring 9, improve the sealing of bellows, right-hand member interface 2 mouth of pipe is provided with the projection 8 of three wave pressure contractings, loose flange 10 is provided with between protruding 8 and seal ring 9, it is more firm that projection 8 makes flange and right-hand member interface 2 mouth of pipe fix.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
Claims (2)
1. bellows, comprise bellows body, bellows body two ends are provided with left end interface and right-hand member interface, it is characterized in that, two ends, described bellows body left and right diameter is identical, described bellows body diameter is increased progressively to centre successively by both sides, bellows body outer surface is provided with the wave that cross section is acute triangle, even transition is provided with between described several acute triangle waves every, described even transition is provided with circular arc burr, the described left end interface mouth of pipe is welded with fastening flange, the right-hand member interface mouth of pipe is provided with the projection of three wave pressure contractings, right-hand member interface end is welded with seal ring, loose flange is provided with between projection and seal ring.
2. bellows according to claim 1, is characterized in that, described bellows body and left and right end interface are formed in one.
