Liquid receiver

Abstract

The invention provides a liquid receiver. The liquid receiver is connected with a compressor and comprises a cylinder body, wherein an intake tube is arranged at the front end of the cylinder body and is provided with a first flange; an iron tube is arranged at the back end of the cylinder body, a centerless grinding iron tube is arranged at the tail end of the iron tube, and a second flange is sleeved outside a connection part of the iron tube and the centerless grinding iron tube and is connected with a compressor shell cylinder body; the centerless grinding iron tube is connected with an air cylinder hole of the compressor through interference fit; the flanges, the cylinder body and the iron tubes are made of an iron material, and the intake tube is made of a copper material; a filter screen and locating bumps are also arranged in the cylinder body, and the locating bumps fix the filter screen on the cylinder body by utilizing a rolling process; the iron tube is provided with locating points for helping the iron tube and the cylinder body to be located in a welding process.

Description

technical field [0001] The invention belongs to the technical field of refrigeration accessories, and in particular relates to a liquid receiver. Background technique [0002] In the prior art, liquid reservoirs (such as figure 1 and figure 2 Shown) including air intake pipe, upper end cover, mesh seat, lower end cover, middle cylinder, air outlet pipe, iron pipe, bracket, filter screen; air inlet pipe and upper end cover are flame brazed; air outlet pipe and iron pipe are flame brazed The iron pipe and the lower end cover are brazed in the furnace; the middle cylinder body, the upper end cover and the lower end cover are brazed in the furnace; the bracket and the iron pipe are brazed in the furnace; It can be seen from the technical scheme that the existing liquid reservoir has problems such as many places to be welded and complex structure, which lead to problems such as unstable welding quality, low welding efficiency, high welding cost and raw material cost in the liq...

Problems solved by technology

[0002] In the prior art, liquid reservoirs (such as figure 1 and figure 2 Shown) including air intake pipe, upper end cover, mesh seat, lower end cover, middle cylinder, air outlet pipe, iron pipe, bracket, filter screen; air inlet pipe and upper end cover are flame brazed; air outlet pipe and iron pipe are flame brazed The iron pipe and the lower end cover are brazed in the furnace; the middle cylinder body, the upper end cover and the lower end cover are brazed in the furnace; the bracket and the iron pipe are brazed in the furnace; It can be seen from the technical scheme that the existing liquid reservoir has problems such as many places that need to be welded and complex structure, so that the liquid reservoir has problems such as unstable welding quality, low welding efficiency, high welding cost and raw material cost.

[0003] Moreover, when the existing liquid receiver is welded to the shell of the compressor, it is necessary to first press the connecting pipe of the cylinder into t
