Description

Water pipe

Technical Field

The utility model belongs to the technical field of the water pipe.

Background

The water pipe is usually connected in the pipe joint, in order to prevent water leakage when the water pipe is used, the water pipe and the pipe joint need to be connected in a sealing mode, and the commonly used sealing structures comprise two types, namely end face sealing, namely a sealing gasket is arranged between the pipe joint and the end face of the water pipe, and radial sealing is adopted, and sealing is completed by using an O-shaped sealing ring between the water pipe and the pipe joint.

When the radial seal is used, in order to make the water pipe and the pipe joint better fit, an expanding part is sometimes arranged on the water pipe, the radial dimension of the expanding part is difficult to keep consistent in the processing process, the pipe wall of the expanding part is easy to be thinned in the processing process, and the structural strength of the water pipe is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's not enough, provide a water pipe, its simple structure, processing is convenient, has better structural strength simultaneously.

In order to solve the above technical problem, the purpose of the present invention can be achieved by the following technical solutions:

the water pipe is connected in a pipe joint of water equipment, the water pipe is a metal pipe, a first diameter expanding part and a second diameter expanding part are sequentially arranged at the connecting end of the water pipe and the pipe joint, an annular groove is formed between the first diameter expanding part and the second diameter expanding part, and the first diameter expanding part and/or the second diameter expanding part are/is formed by stacking a plurality of sections of radial folding pipe walls.

The water pipe is a stainless steel pipe or a copper pipe, preferably a copper pipe.

The inner wall surface of the folding pipe wall is the same as that of the water pipe, and the radial dimension of the folding pipe wall is the same.

Preferably, the ratio of the radial dimension of the folded pipe wall to the wall thickness of the water pipe is 3:1-10: 1.

Preferably, the first diameter-expanding part is formed by stacking 1-2 sections of folded pipe walls, and the second diameter-expanding part is formed by stacking 2-5 sections of folded pipe walls.

The connecting end of the water pipe, which is opposite to the pipe joint, is sequentially provided with a flaring part and a third flaring part, and the third flaring part is formed by stacking a plurality of sections of radial folding pipe walls.

The third expanding part is formed by stacking 1-3 sections of folded pipe walls, and the folded pipe walls of the third expanding part are the same as those of the first expanding part and the second expanding part.

The water pipe is provided with a plurality of bending parts, and the bending parts are positioned at the position of the water pipe close to the connecting end and/or the middle part of the water pipe.

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

the utility model forms the expanding part through the folding tube wall, and has higher structural strength compared with the expanding part formed by stretching; the folding pipe wall is formed by extrusion, so that the processing is easier; in addition, the folded pipe wall can easily keep the same radial dimension during processing, so that the water pipe and the pipe joint have better matching degree.

Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which figures 1 to 3:

one end of a water pipe 1 is connected in a pipe joint of water equipment, the water pipe 1 is a metal pipe, a first diameter-expanding part 2 and a second diameter-expanding part 3 are sequentially arranged at the connecting end of the water pipe 1 and the pipe joint, an annular groove 4 is formed between the first diameter-expanding part 2 and the second diameter-expanding part 3, and the first diameter-expanding part 2 and/or the second diameter-expanding part 3 are/is formed by stacking a plurality of sections of radial folded pipe walls.

The folding pipe wall is formed by extrusion, one section of the pipe wall is folded at one time during processing, and the other section of the pipe wall is processed after the folding of one section of the pipe wall is finished until the processing is finished. When the water pipe is used, the O-shaped sealing ring is sleeved in the annular groove 4, then the water pipe 1 is placed in the pipe joint, the water pipe 1 and the pipe joint are radially sealed through the O-shaped sealing ring 4, and finally the water pipe 1 and the pipe joint are fixed.

The water pipe 1 is a stainless steel pipe or a copper pipe, preferably a copper pipe.

Referring to fig. 2 and fig. 3, the inner wall surface of the folded pipe wall is the same as the inner wall surface of the water pipe 1, i.e. the same cylindrical surface, and the radial dimensions of the folded pipe wall are the same.

Preferably, the ratio of the radial dimension of the folded pipe wall to the pipe wall thickness of the water pipe 1 is 3:1-10: 1; preferably 4: 1-6:1.

Preferably, the first diameter-expanding part 2 is formed by stacking 1-2 sections of folded pipe walls, and the second diameter-expanding part 3 is formed by stacking 2-5 sections of folded pipe walls.

The connecting end of the water pipe 1 opposite to the pipe joint is sequentially provided with a flaring part 5 and a third diameter-expanding part 6, and the third diameter-expanding part 6 is formed by stacking a plurality of sections of radial folded pipe walls.
