Problems solved by technology

However, in actual use, there are still many defects in the bridge bend joint.
For example, due to the development of existing building materials, we can use thinner walls to complete the function of thick walls in the past, and use larger water pipes to ensure the use of large water flows, but the bridge parts required for water pipes in the case of intersections will occupy Large volume, thin wall cannot be installed

Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] see Figure 1~2 , a bridge piece, including pipe fittings 1 used in pairs, both ends of the pipe fittings 1 are compression joints 2, the middle part of the pipe fitting 1 is a curved part 3 that is bent to one side as a whole, and the bending directions of different pipe fittings 1 are opposite .

[0031] The pipe fittings 1 used in pairs can reduce the contact of adjacent pipes when the pipes cross, and the pipe fittings 1 used in pairs can reduce the overall curvature of the bridge, and can also be used on thinner walls; And the setting of the pressing joint 2 makes the installation more convenient and convenient.

[0032] The curved part 3 includes an upper arch point 31 and a lower arch point 32, the upper arch point 31 is higher than the outer diameter of the compression joint 2 and lower than 1.5 times the outer diameter of the compress...

Abstract

The invention relates to the technical field of pipelines, in particular to a bridge crossing part. The part comprises pipe fittings which are used in pairs, two ends of the pipe fittings are providedwith clamping pressing joints, the middle of each pipe fitting is a bending part wholly bent towards one side, the bending directions of the different pipe fittings are opposite, and the invention further provides a preparing method of the bridge crossing part. The part is simple in structure, and convenient to use, the pipe fittings which are used in pairs are arranged, under the condition thatpipelines are crossed, contact between adjacent pipelines can be reduced, the pipe fittings which are used in pairs enable the total bending degree of the bridge crossing part to be reduced, the thinwall also can be used, and due to the clamping pressing joints, mounting is more convenient, and rapid.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a bridge piece and a preparation method thereof. Background technique [0002] The bridge elbow joint is widely used in the connection of pipe fittings, and it is also the simplest and most practical structure in the interlaced parts of pipe fittings. Especially in the case where two water pipes intersect up and down, if the bridge bend is not used, the water pipe above will be pushed and deformed. Especially in some places where tee joints are used, the joints will be pushed and skewed, and the skewed joints will leak after a long time. Therefore, people need to check the upper and lower intersections of the water pipes during installation to see if they need to install bridge bend joints to prevent the water pipes from being squeezed and causing the joints to loosen and cause water leakage. But in actual use, there are still many defects in the bridge bend joint. For examp...
