Problems solved by technology

Due to the defects in the manufacturing process of the Y-shaped trousers tee of the traditional air conditioner branch pipe, the welding socket of the straight pipe and the bent pipe is flattened, shaped, and brazed and bonded. It is not a complete independent pipe. mouth, so there is uneven welding at the weld, poor fastness, and it is easy to burst under high pressure

Embodiment Construction

[0012] Such as figure 1 As shown, the present invention mainly consists of a straight pipe 5 and a long straight pipe 1 located at the end of the straight pipe 5 and bifurcated welding sockets 2 and 6 of the bent pipe 7 to form a trousers tee 4. The bifurcated welding socket 2 and 6 are independent seamless nozzles. The trousers tee is provided with a bifurcated opening 3, which is arc-shaped. on flat surface.

[0013] Such as figure 2 , image 3 As shown, the bifurcated welding sockets 2 and 6 on the trousers tee 4 of the present invention are independent seamless nozzles. The sockets 2, 6 are parallel to the center line of the straight pipe 5 and are on the same plane.

[0014] The manufacturing process of the present invention adopts the hydraulic extrusion process technology, and the copper pipe is passed through a special trousers tee mold, and the welded sockets of the straight pipe and the bent pipe are extruded into independent seamless pipe trousers tees.

Abstract

The invention discloses a manifold and a manufacturing process thereof. The manifold is a pants tee comprising a straight pipe and branched welding bellmouths of a long straight pipe and a bent pipe which are arranged at the ends of the straight pipe, wherein the branched welding bellmouths are independent seamless pipe mouths, branched mouths in a circular-arc shape are arranged on the pants tee, and the two branched welding bellmouths and the central line of the straight line are parallel and are on the same plane. In the manufacturing process of the manifold, by adopting a hydraulic extrusion process, a copper pipe is extruded into a pants tee comprising welding bellmouths of a long straight pipe and a bent pipe, wherein the welding bellmouths are independent seamless pipe mouths. The invention is suitable for manufacturing the manifold of an air conditioner.

Description

technical field [0001] The invention relates to a branch pipe for an air conditioner, in particular to a branch pipe and a manufacturing process thereof. Background technique [0002] The quality of the branch pipe used in the air conditioner is related to the performance of the whole air conditioner. Due to the defects in the manufacturing process of the Y-shaped trousers tee of the traditional air conditioner branch pipe, the welding socket of the straight pipe and the bent pipe is flattened, shaped, and brazed and bonded. It is not a complete independent pipe. mouth, so there is uneven welding at the weld, poor fastness, and it is easy to burst under high pressure. Contents of the invention [0003] The object of the present invention is to provide a branch pipe with novel design, higher process requirements and better quality in view of the shortcomings of the above branch pipe. [0004] In order to achieve the above object, the present invention is mainly realized b...
