Abstract
The utility model relates to a metallic corrugated pipe piece which is composed of a section of a body of a corrugated pipe, wherein at least one end of the body of the corrugated pipe is integrally provided with a connecting pipe with a reducible pipe diameter and both ends of the body of the corrugated pipe can equally provided with smooth connecting pipes with reducible pipe diameters. The connecting pipes can be straight pipes with smooth walls; each of the pipe diameters of the connecting pipes is not smaller than the inner diameter of a wave trough and not greater than the outer diameter of a wave peak. Each of the pipe diameters of the straight pipes with the smooth walls is smaller than the outer diameter of the wave peak. The utility model has the characteristics of simple structure, convenient operation, strong versatility, convenient population and application, etc. The utility model can be made into metallic corrugated pipe pieces with different standards to be matched, installed and connected with openings of connecting pipes or valves of different standards. Moreover, the utility model can be made into a metallic corrugated pipe with a connecting opening of a big pipe diameter according to the actual demand.
Description
Technical field
The utility model relates to the wavy metal pipe fitting that a kind of pipeline connects usefulness, belong to the pipe fitting that connects usefulness.
Background technique
In the prior art, bellows part is mainly used in the connection of pipeline, the connection of especially scalable pipeline, but seen in the market wavy metal pipe fitting, be the pipe fitting that a section bellows body constitutes, its body specification of making is difficult to be connected the connection that matches of the mouth of pipe or valve with having now.As the shallow corrugated pipe, the shallow corrugated pipe of " bore; actual latus rectum (bore) all has only Φ about 16, also should claim 5/8 " nominally all be referred to as 3/4, reason are to be fixed on the waterway fitting 3/4 " nut at the bottom of the footpath size restrictions produce the bore of shallow corrugated pipe.Though existing shallow corrugated pipe can be realized the flexible connection of connecting tube,, cause the existence of problems such as the little and versatility difference of its actual latus rectum because of the caliber of above-mentioned metal bellows and existing conventional connecting tube or valve caliber do not match.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of versatility better, can supportingly be applicable to that existing specification connects the mouth of pipe or valve and wavy metal pipe fitting that actual latus rectum can not dwindle, it is made of one section bellows body at least, and at least one end one of described bellows body is shaped on the one section adapter that can dwindle caliber.
The two ends of described bellows body all are shaped on the one section adapter that can dwindle caliber, and the caliber of taking over be not less than trough internal diameter, be not more than the external diameter of crest.
Described adapter is a light wall straight tube, and its caliber is less than the external diameter of crest,
The utility model compared with prior art, have simple in structure, easy to use, highly versatile, can make the wavy metal pipe fitting of different size and connect with the supporting installation of the mouth of pipe or valve that is connected of different size, and can make the metal bellows of big caliber interface according to actual needs, characteristics such as easy to utilize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model is made of at least one section bellows body 1, and at least one end one of described bellows body 1 is shaped on the one section adapter 2 that can dwindle caliber.Shown in Figure 1, all be shaped on the one section adapter 2 that can dwindle caliber at the two ends of described bellows body 1, and this is taken over and is that light wall straight tube, the caliber of described smooth wall straight tube are not less than the internal diameter of trough 3, are not more than the external diameter of crest 4.The caliber of light wall straight tube shown in Figure 1 can dwindle the bore of bellows, and the caliber of bellows body can strengthen, and to adapt to the connection mouth of pipe or the valve of different size, reaches the technical standard flow of regulation shallow corrugated pipe less than the external diameter of crest 4.Described bellows body 1 is to make after thin aluminum sheet is suppressed with specialized mould, belongs to existing routine techniques content because of making metal bellows, so be not described in detail.
Claims (3)
