Abstract

The utility model relates to a liquid-storing device used for the Freon refrigerating system, belonging to the assistant equipment of the Freon refrigeration system. The utility model comprises a barrel body, an upper end-cover, a lower end-cover, a liquid intake pipe, a liquid draining pipe and a strainer component arranged on the lower part of the liquid draining pipe. And the liquid draining pipe is formed by the connection of the copper barrel-outer connecting section of the liquid draining pipe and the steel barrel-inner section of the liquid draining pipe. An inserting adapter is arranged at one end of the barrel-inner section which extends out of the barrel-casing, and the outer wall of the adapter is welded and fixedly sealed with the outlet of the liquid draining pipe on the upper end-cover. One end of the barrel-outer connecting section of the liquid drain pipe is inserted into the inserting adapter of the barrel-inner section and is welded with the adapter. The utility model adopts the combination of steel pipe and copper pipe to replace the overall copper pipeline of the liquid tank, and then the manufacturing cost is reduced. And the structure is simple and the manufacturing process is convenient, and a better welding capability between the pipelines of the system can be preserved.

Description

A kind of freon refrigeration system reservoir

Technical field

The utility model relates to a kind of refrigeration system auxiliary equipment, especially relates to a kind of high pressure reservoir of freon refrigeration system.

Background technology

Relatively large refrigeration system often must be provided with the high pressure reservoir, the high pressure reservoir is arranged on after the condenser, in order to store by the next highly pressurised liquid of condenser, when system's thermic load changes, regulate the refrigerant feed liquid amount, it also plays the fluid-tight effect, scurries into low pressure line to prevent higher pressure refrigerant gas.In the prior art because the pipeline of freon refrigeration system generally adopts pure copper tube, for guarantee and system pipeline between good welding performance is arranged, all whole copper pipe that adopts of the liquid in-out pipeline of the reservoir of traditional freon refrigeration system.This structure has increased the copper pipe consumption undoubtedly, has increased manufacturing cost.

Summary of the invention

In order to solve existing freon refrigeration system reservoir, the copper pipe large usage quantity, the defective that production cost is higher, the utility model provides a kind of use steel pipe instead of part copper pipe, keep liquid in-out to take over simultaneously and still have the good welds performance, do not increase a kind of freon refrigeration system reservoir of making difficulty of processing again with system pipeline.

The technical scheme that its technical problem that solves the utility model adopts is: the freon refrigeration system reservoir, comprise cylindrical shell, end cap, feed tube, drain pipe and the filtering net part that is installed in the drain pipe bottom, cylindrical shell and last, bottom end cover is welded into the barrel shell of sealing, its drain pipe of reservoir is that the outer linkage section of fluid socket and the material of copper pipe is that the fluid socket inner segment of steel pipe is connected and combines by material, the fluid socket inner segment that is installed on barrel shell inside stretches out this end of barrel shell from the outlet of upper end cover drain pipe and is provided with the plug-in type interface, this interface outer wall and upper end cover drain pipe outlet welding sealing, be positioned at the outer linkage section of the outer fluid socket of barrel shell, the one end inserts the plug-in type interface of fluid socket inner segment, and with the joint weld sealing.

The utility model is all right: the reservoir feed tube is that the outer linkage section of feed liquor socket and the material of copper pipe is that the feed liquor socket inner segment of steel pipe is connected and combines by material, the feed liquor socket inner segment that is installed on barrel shell inside stretches out this end of barrel shell and is provided with the plug-in type interface, this interface outer wall and upper end cover feed tube outlet welding sealing, be positioned at the plug-in type interface that outer linkage section one end of the outer feed liquor socket of barrel shell inserts feed liquor socket inner segment, and with the joint weld sealing.

The utility model has reduced production cost owing to replace existing reservoir feed liquor, the full copper pipe of fluid with the combining structure of steel pipe, copper pipe, and simple in structure, easy to process, kept and system pipeline between good welding performance.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model structure is described further.

Fig. 1 partly cuts open structural representation for embodiment's of the utility model.

Fig. 2 is the partial view that partly cuts open structural representation of another embodiment of the utility model.

Among the figure: 1, cylindrical shell; 1.1, upper end cover; 1.2 bottom end cover; 2, lining; 3, feed tube; 3.1 the outer linkage section of feed liquor socket; 3.2.1, feed tube plug-in type interface; 3.2, feed liquor socket inner segment; 4.1, the outer linkage section of fluid socket; 4.2.1, drain pipe plug-in type interface; 4.2, fluid socket inner segment; 5, filtering net part.

The specific embodiment

In embodiment illustrated in fig. 1, the freon refrigeration system reservoir is made up of cylindrical shell 1, upper end cover 1.1, bottom end cover 1.2, lining 2, feed tube 3, the outer linkage section 4.1 of fluid socket, fluid socket inner segment 4.2, filtering net part 5 etc.Feed tube 3 is a copper pipe, and it enters the pipeline section outer wall welding of barrel shell place and is enclosed in admittedly in the steel sleeve 2, the feed tube outlet welding sealing on lining 2 outer walls and the upper end cover 1.1.The fluid socket inner segment 4.2 that is installed on barrel shell inside adopts steel pipe, replace original copper pipe structure, its drain pipe that stretches out on the upper end cover 1.1 exports the plug-in type interface 4.2.1 that this end is provided with enlarging formation, the drain pipe outlet welding sealing on drain pipe plug-in type interface 4.2.1 outer wall and the upper end cover 1.1.Be positioned at the outer linkage section 4.1 of the outer fluid socket of barrel shell and adopt the copper pipe identical with the refrigeration system pipe material, the one end inserts among the drain pipe plug-in type interface 4.2.1, with the joint weld sealing.

Another embodiment shown in Figure 2, its drain pipe two-part steel pipe, copper pipe combining structure are identical with the drain pipe structure of Fig. 1 embodiment.Fig. 2 embodiment feed tube also is steel pipe, copper pipe combining structure, by the material that is installed on barrel shell inside is that the upper end enlarging of the feed liquor socket inner segment 3.2 of steel pipe forms plug-in type interface 3.2.1, plug-in type interface 3.2.1 stretches out barrel shell and its outer wall and upper shell 2 feed tubes outlet welding sealing, be positioned at the outer linkage section 3.1 of the outer feed liquor socket of barrel shell and adopt the copper pipe identical with the refrigeration system pipe material, the one end inserts among the feed tube plug-in type interface 3.2.1, and the joint weld sealing.
