Description

Oblique pulling type branch pipe

Technical Field

The utility model belongs to the technical field of branch pipes, and particularly relates to an inclined-pulling type branch pipe.

Background

The branch pipe is also called an air conditioner branch pipe or a branch pipe, and is a connecting pipe for connecting a host machine and a plurality of end devices (evaporators) in a VRV air conditioning system, and is divided into an air pipe and a liquid pipe. The trachea is generally thicker than the tube. The refrigerant is throttled by an expansion valve or capillary tube and then exits the host outlet before being connected to the branch liquid line. The refrigerant is split through the liquid tubes to separate the other branch tubes and the end evaporators. The refrigerant is converted into gas by heat absorption in the evaporator and then flows back to the compressor of the main unit through the gas pipe.

At present, in a refrigerating system, a branch pipe is assembled and welded by 4 parts, and the branch pipe is mainly divided by a brass tee joint and a copper tee joint, so that the processing cost of the branch pipe is high, the number of welded junctions is large, and the production efficiency is low.

Disclosure of Invention

The present utility model is directed to an inclined-pulling type branch pipe, which solves the above-mentioned problems in the prior art.

The technical scheme adopted by the utility model is as follows:

the utility model provides an oblique pull type branch pipe, includes the main pipe, be responsible for both sides and seted up oblique pull hole and No. two oblique pull holes respectively, the downthehole intubate of oblique pull is equipped with a piping, no. two oblique pull hole interpolation is equipped with No. two pipings.

Preferably, the first inclined drawing hole and the second inclined drawing hole adopt symmetrical structures, and the symmetrical axis is the central axis of the main pipe.

Preferably, the pipe diameters of the first pipe and the second pipe are smaller than the pipe diameter of the main pipe.

Preferably, the lengths of the first pipe and the second pipe are smaller than the length of the main pipe.

Preferably, welding is adopted between the first piping and the second piping and the main pipe.

Preferably, the walls of the first inclined drawing hole and the second inclined drawing hole adopt inclined cylindrical structures.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

in the utility model, the three-way connection in the middle of the conventional branch pipe is canceled, thereby achieving the effects of saving the material cost, reducing the number of welded junctions and improving the processing efficiency.
