Description

Corrosion-resistant corrugated pipe

Technical Field

The utility model relates to a bellows technical field especially relates to an anti corrosion bellows.

Background

The compensator using the corrugated pipe as a telescopic compensation element has small volume, good flexibility and simple and convenient installation and transportation, and increasingly becomes an indispensable important pipe fitting in the laying process of a thermal pipeline; the anticorrosion measures of brushing the anticorrosion paint outside the corrugated pipe can not achieve the corresponding anticorrosion effect due to uneven brushing caused by the inconvenience of brushing and the high-temperature cracking of the paint.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems existing in the prior art and providing an anti-corrosion corrugated pipe.

The technical scheme is as follows: the utility model provides an anti-corrosion corrugated pipe, includes the bellows body, bellows body length direction's both ends all are provided with a plurality of ripple layers, both ends the ripple layer number of piles is the same, bellows body length direction both ends are provided with disk seat and mouth of pipe respectively, the outside cladding of bellows body has an inoxidizing coating, the inoxidizing coating specifically is the nickel alloy board, the wall lining is equipped with an anticorrosive fluorine layer in the bellows body.

Preferably, the valve seat is arranged in a step shape in cross section.

Preferably, the corrugated pipe body is in a tubular arrangement, and the surface diameter of the corrugated layer is consistent with that of the corrugated pipe body.

Preferably, the thickness of each corrugated layer is not less than 1.4mm, and the height of each corrugated layer is 25 mm.

Preferably, the corrugations of the corrugated layers are U-shaped, and the number of the corrugated layers at each end is 4-6.

Compared with the prior art, the utility model discloses possess following beneficial effect:

1. the utility model discloses a mutually supporting of bellows body, ripple layer and disk seat avoids the bellows to produce the phenomenon of checking a crack or corroding in the use, improves the life of bellows.

Fig. 1 is a front view of the overall structure of a corrosion-resistant corrugated pipe according to the present invention;

fig. 2 is a schematic view of a part of the structure of a corrosion-resistant corrugated pipe according to the present invention;

in the figure: 1. a bellows body; 2. a corrugated layer; 3. a valve seat; 4. a pipe orifice; 5. a protective layer; 6. and an anti-corrosion fluorine layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 2, a corrosion-resistant corrugated pipe includes a corrugated pipe body 1, wherein a plurality of corrugated layers 2 are respectively disposed at two ends of the corrugated pipe body 1 in a length direction, and pressure applied to each corrugated portion of the corrugated layers 2 is uniform; the layers of the corrugated layers 2 at the two ends are the same, the two ends of the corrugated body 1 in the length direction are respectively provided with a valve seat 3 and a pipe orifice 4, and the valve seats 3 are used for connecting the corrugated body with a water delivery pipe; the outside cladding of bellows body 1 has an inoxidizing coating 5, inoxidizing coating 5 plays the guard action when the bellows receives corruption such as sour water, improves the life of bellows, inoxidizing coating 5 specifically is the nickel alloy board, 1 interior wall liner of bellows body is equipped with an anticorrosive fluorine layer 6, anticorrosive fluorine layer 6 carries out anticorrosive protection to the inner wall of bellows, guarantees that the inner wall of bellows can not corroded by the sour water etc. of circulation, improves the life of bellows.

The section of the valve seat 2 is arranged in a step shape, so that the corrugated pipe can be conveniently fixed subsequently.

The corrugated pipe body 1 is arranged in a tubular shape, and the surface diameter of the corrugated layer 2 is consistent with that of the corrugated pipe body 1.

The thickness of the corrugated layer 2 is not less than 1.4mm, and the corrugation height of the corrugated layer 2 is 25 mm.

The corrugations of the corrugated layer 2 are U-shaped, so that the pressure applied to each corrugated part of the corrugated layer 2 is uniform, and the number of the corrugated layer 2 at each end is 4-6.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
