Abstract

The utility model relates to the technical field of water pipes and fittings thereof, in particular to a burst-proof water pipe and a joint for the burst-proof water pipe. The burst-proof water pipe comprises a water pipe body, and the pipe wall of the water pipe body is in a wavy folded shape along a radial direction. The joint for the water pipe comprises a joint body, and a wavy folded connecting grain anastomotic with the outer wall of the pipe wall of the water pipe body is molded on the inner wall of a port of the joint body. The pipe wall of the water pipe, provided by the utility model, is in the wavy folded shape; when being suffered from icing tension, the folded pipe wall can generate proper deformation to increase the cubage in the pipe, so that the tension of icing to the pile wall can be relieved; and the effect of preventing the water pipe from bursting is achieved. Simultaneously, the corresponding joint for the water pipe is designed so as to quickly connect and assemble the water pipe.

Description

A kind of anti-explosion water pipe and be used for the joint of this anti-explosion water pipe

Technical field:

The utility model relates to water pipe and accessory technical field thereof, refers in particular to a kind of anti-explosion water pipe and is used for the joint of this anti-explosion water pipe.

Background technique:

Existing water pipe has metallic water pipe and nonmetal water pipe, all is designed to hollow cylindrical.When temperature was very low, the water in the outdoor water pipe was easy to freeze, and increased because water density when icing reduces volume, and therefore can expand produces very big tension force to the water pipe tube wall, for metallic water pipe, because its intensity is higher, therefore can not be out of shape easily; And for nonmetal water pipe, powerful tension force is easy to columned nonmetal water pipe is risen brokenly, causes a large amount of current to lose waste, makes troubles to urbanite water consumption.

The model utility content:

The joint that the purpose of the utility model is that a kind of anti-explosion water pipe is provided and is used for this anti-explosion water pipe.

The utility model realizes that the technological scheme that its purpose adopts is: a kind of anti-explosion water pipe, have a water pipe body, and the tube wall of said water pipe body radially is the wave fold shape.

A kind of joint that is used for above-mentioned anti-explosion water pipe has a joint body, and the port inner wall of said joint body forms the wave fold shape that matches with said water pipe body tube wall outer wall and is connected lines.

The tube wall of the utility model water pipe is the wave fold shape, and when receiving when freezing tension force, the deformation that the tube wall of fold shape can produce appropriateness increases the pipe internal volume, thereby can alleviate the tension force that freezes to tube wall, plays the effect of anti-water stopping tube explosion.The corresponding water pipe adapter of design simultaneously is to assemble water pipe fast.

Description of drawings:

Fig. 1 is the structural representation of the anti-explosion water pipe of the utility model;

Fig. 2 is the structural representation of the utility model water pipe adapter.

Embodiment:

Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.

Like Fig. 1, shown in 2, the described anti-explosion of the utility model is split water pipe and is had a water pipe body 1, and it is characterized in that: the tube wall of said water pipe body 1 radially is the wave fold shape; Accordingly, the described joint of the utility model has a joint body 2, and the port inner wall of said joint body 2 forms the wave fold shape that matches with said water pipe body 1 tube wall outer wall and is connected lines 21.

During assembling; Apply with the port inner wall of sealer earlier at water pipe body 1 end outer wall and joint body 2; Then the end of water pipe body 1 is inserted the port of joint body 2; Coincide because the fold shape of water pipe body 1 outer wall is connected lines 21 with the fold shape of joint body 2 port inner walls, therefore butt joint back gelling to be sealed gets final product admittedly, and assembling fast.

Certainly; The anti-explosion water pipe of the utility model also can be used with common water pipe; This moment, one end and anti-explosion water pipe body 1 outer wall of joint body 2 coincide, and promptly this port inner wall is provided with fold shape connection lines 21, and the other end then coincide with common pipe outer wall; Promptly this port inner wall is not provided with the fold shape lines, but regular screw threads is set or does not establish any lines.

Anti-explosion water pipe of the utility model and joint thereof adopt existing PP-R material to make by existing technology and get final product; The tube wall of water pipe is the wave fold shape; When receiving when freezing tension force; The deformation that the tube wall of fold shape can produce appropriateness increases the pipe internal volume, thereby can alleviate the tension force that freezes to tube wall, plays the effect of anti-water stopping tube explosion.The corresponding water pipe adapter of design simultaneously is to assemble water pipe fast.

Claims

1. an anti-explosion water pipe has a water pipe body (1), and it is characterized in that: the tube wall of said water pipe body (1) radially is the wave fold shape.

2. joint that is used for the described anti-explosion water pipe of claim 1; Have a joint body (2), it is characterized in that: the port inner wall of said joint body (2) forms the wave fold shape that matches with said water pipe body (1) tube wall outer wall and is connected lines (21).
