Description

Air conditioner compressor cylinder intubate

Technical Field

The utility model relates to a compressor spare part technical field, concretely relates to air condition compressor cylinder intubate.

Background

When the air condition compressor cylinder intubate carries out outer hole butt joint as gas transmission's important part and compressor, can not carry out real-time regulation to the aperture of equidimension not, need cooperate through the punching press hole of difference, generally can have certain clearance when butt joint to the outer tube simultaneously, and sealing performance is not strong, causes the leakage easily, influences the joint effect between the pipe fitting, reduces finished product quality, is unfavorable for the use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an air condition compressor cylinder intubate provides an air condition compressor cylinder intubate that excellent in use effect, manufacturability are strong and sealed effectual.

In order to realize the above purpose, the utility model discloses a technical scheme be: the utility model provides an air condition compressor cylinder intubate, includes the cylinder intubate body, its characterized in that, what the cylinder intubate body adopted is the steel pipe overcoat and arranges the copper pipe spare on the steel pipe overcoat inner wall in, set firmly in the copper pipe spare and run through the inside centre bore of copper pipe spare, and go up the upset portion that the processing a pair of symmetry set up and outwards extend on the cylinder intubate body, and upset portion and outside compressor directly carry out the welding mode and carry out fixed connection, copper pipe spare inner wall one end is equipped with the reaming, and the reaming can carry out the preprocessing according to the aperture size of the grafting pipe of compressor butt joint, copper pipe spare inner wall other end roof department is equipped with the elastic component of being made by alloy material, the elastic component with through joint ring fixed connection between the steel pipe overcoat, just copper pipe spare top both sides are all through the processing of chamfering in advance.

Furthermore, the thickness of the inner wall of the copper pipe fitting is 0.5-10mm, the top chamfer angle is 15-30 degrees, and the Morse taper of the reaming is No. 1.

Furthermore, the thickness of the inner wall of the copper pipe fitting is 0.8mm, the top chamfer angle is 20 degrees, and four processing modes of an original pipe, flaring, necking and bending can be adopted for combination.

The technical effects of the utility model reside in that: the connecting mode is connected through resistance weld's mode particularly between cylinder intubate body and the compressor, can better reduce cost, has avoided using high silver solder welding, can practice thrift pipe fitting and compressor host computer welded high silver solder expense moreover, more can effectively reduce the compressor and leak, reduces the energy consumption, and the pipe fitting inner wall adopts elastic component cooperation joint ring, better leakproofness when having better guaranteed the pipe fitting butt joint, excellent in use effect, the application is strong.
