Description
Technical field
The utility model relates to liquid storage device technical fields, it particularly relates to a kind of upper end for three-stage liquid storage device
Lid net-filter assembly.
Background technique
Liquid storage device is the important component of compressor, plays the work of storage, gas-liquid separation, filtering, noise reduction and refrigerant buffering
With being by components such as cylinder (BODY), air inlet pipe (INLET PIPE), escape pipe (OUTLET PIPE), strainers (SCREEN)
Composition.Liquid storage cylinder and be incorporated on liquid storage cylinder be connected to liquid storage cylinder inside air inlet pipe and exhaust pipe, work
Principle is as follows:
Liquid storage device is to be fitted in A/C evaporator and compressor suction duct position, is to prevent liquid refrigerant from flowing into compressor
And generate the guard block of liquid hammer.In air-conditioning system operating, not can guarantee refrigerant can all be completely vaporized；Namely from steaming
The refrigerant that the refrigerant that hair device comes out has liquid enters in liquid storage device, since the liquid refrigerant not vaporized is because itself compares
Gas weight can directly put off liquid storage device cylinder bottom, and the refrigerant of vaporization is then entered in compressor by the outlet of liquid storage device, to prevent
Compressor sucking liquid refrigerant causes liquid hammer.Liquid storage device component is in service firing, to avoid the impurity in pipeline direct
Into in compressor, so in air inlet pipe of liquid storage device to will be installed strainer between escape pipe, it is therefore prevented that impurity enters compressor
It may.
The long-term operating of compressor, inside have certain lubricating oil with vaporization refrigerant be discharged, pass through pipeline
It can enter in liquid storage cylinder, the escape pipe due to being welded on liquid storage cylinder bottom has processing one " oil return hole ", so precipitating
Power is made by the suction of compressor in the lubricating oil of cylinder body bottom, return the escape pipe of liquid storage device not only but also is entered in compressor, from
And play the role of lubrication protection to compressor.
Existing three-stage liquid storage device generally comprises ontology, upper end cover, lower cover, net-filter assembly, inner tube, air inlet pipe, goes out
Seven component compositions such as tracheae, wherein net-filter assembly is made of three pressing ring, strainer, supporting plate parts, and three parts use resistance
Weldering is combined, and the part material needed is more, and production process is cumbersome.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of upper ends for three-stage liquid storage device
Lid net-filter assembly can overcome the above-mentioned deficiency of the prior art.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of upper end cover net-filter assembly for three-stage liquid storage device, including upper end cover, upper end cover is interior to be equipped with strainer and support
Plate, strainer are clipped between upper end cover and supporting plate, and strainer, supporting plate are welded to connect with upper end cover.
Further, the upper end cover and strainer and supporting plate use electric resistance welding.
Further, the upper end cover is equipped with the step of fixed strainer and supporting plate.
Further, the upper end cover is equipped with air inlet openings.
The utility model has the beneficial effects that the upper end cover net-filter assembly for three-stage liquid storage device of the utility model passes through
It combines strainer using electric resistance welding with upper end cover, with the upper end cover used in existing three-stage liquid storage device compared with net-filter assembly
Pressing ring can be reduced；Supporting plate does not need reverse-drawing and rolling ditch；Reduce solder, the assembly of net-filter assembly is reduced in production, was both saved
About part material, and reduce production process, and then achieve the purpose that save cost.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figs. 1-2, the upper end cover strainer group of three-stage liquid storage device is used for according to the utility model embodiment
Part, including upper end cover 1, strainer 2 and supporting plate 3, upper end cover 1 are equipped with the step of fixed strainer 2 and supporting plate 3, and strainer 2 is clipped in upper end cover
Between 1 and supporting plate 3, upper end cover 1 and strainer 2 and supporting plate 3 use electric resistance welding.Upper end cover 1 is equipped with for connecting air inlet pipe
Air inlet openings.
The installation process of upper end cover net-filter assembly is that strainer is put at the step of upper end cover, places into supporting plate, makes supporting plate
Strainer is pressed at the step of upper end cover, then these three components are connected together by Resistance Welding.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
As shown in figure 4, when assembling three-stage liquid storage device using the upper end cover net-filter assembly of the utility model, it directly will be upper
End cap net-filter assembly and ontology and the lower cover for being equipped with inner tube assemble, then erection welding air inlet pipe and an air outlet pipe.
As shown in figure 3, the assembly technology of existing three-stage liquid storage device is to obtain pressing ring, strainer, supporting plate electric welding combination
Net-filter assembly (net-filter assembly needs to roll ditch and is put into solder in the trench) and ontology assemble welding, then assemble upper end cover and
It is equipped with the lower cover of inner tube, finally reassembles welding air inlet pipe and an air outlet pipe.
In conclusion the assembly technology of existing three-stage liquid storage device needs pressing ring, supporting plate needs reverse-drawing, and sub-assembly needs
It wants electric resistance welding to connect, rolls ditch, net-filter assembly needs individually to assemble and be welded with material to be welded and fixed with ontology；It is practical new using this
The upper end cover net-filter assembly of type assembles three-stage liquid storage device, and supporting plate material reduces, and does not need reverse-drawing, does not need rolling ditch, support
Plate is combined with strainer, upper end cover electric resistance welding, does not need pressing ring；Reduce the assembly of net-filter assembly and ontology；Reduce solder and
Process is welded and fixed.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
