The assembling difficulty of vapour liquid separator in low the present embodiment.
Specifically, it is connected, can be effectively protected by argon arc welding between the end cap 12 and shell 10 in the present embodiment
Demonstrate,prove the mechanical property of each part of the vapour liquid separator in the present embodiment.
Referring again to shown in Fig. 1 to Fig. 8, according to the above embodiments it is recognised that the vapour liquid separator of the present invention is main
Including following 8 part：Shell 10；Swash plate 20；Escape pipe 40；Installing plate outside shell 10；Fixed plate 60；Support tube
30；Filter 50.Primary structure and its feature are as follows：End cap 12 is provided with shell 10, there is import 122 and outlet on end cap 12
121, and exterior line environmental protection joint fitted seal, overall is in two-stage step, and small end part mainly coordinates with shell 10；Anti- ripple
The corner of plate 20 there are about 45 ° or so of slope (similar with chamfering), ensure that there is certain barrier to make to the gas of import 122
With allowing simultaneously, gas flowing is smooth, and it is excessive to be unlikely to pressure drop；Support tube 30 is a cylindrical structural, and inwall bottom has 4 to determine
Escape pipe 40 is positioned in support tube 30 by position muscle 32 by being interference fitted, and bottom oilhole 311 once, on support tube 30
There is rounding globoidal structure on surface, makes gas flowfield more smooth, in order to avoid the pressure difference of air inlet and outlet is excessive, support tube 30
The sectional area S1 in the water conservancy diversion gap 70 between the escape pipe 40 and internal diameter sectional area S2 of escape pipe 40 ratio is about 2.2 to arrive
3.0, i.e.,:S1/S2=2.2~3.
Following optimization is made with existing vapour liquid separator structure compared：Conventional U-shaped escape pipe is changed to escape pipe
40 and support tube 30, the bottom that the ring support of the bottom of support tube 30 and filter 50 is connected directly with shell 10 contacts, and improves
The resistance to vibration of pipeline herein, while increase fixed plate 60 outside support tube 30 connect support tube 30 and shell 10, enter one
Step improves the resistance to vibration of pipeline, to meet the requirement of automobile.Vapour liquid separator filter 50 is by ring support 51 and nylon
Net composition, ring support 51 are directly connected with the interference fit of support tube 30, cancel the existing welding procedure of copper pipe and iron filter 50,
Reduce by one of welding sequence.
Swash plate 20 on the corner has obvious inclined structure (being right angle in the past), and the gas that can be allowed into is beaten
On plate, allow liquid to be attached on swash plate 20, be easy to the separation of vapour-liquid, 20 inclined structure of swash plate meets the same of barrier liquid
When pressure is not had excessive loss；Swash plate 20 is fastened in cavity 11 by the outward flange 41 of escape pipe 40, and outlet
Pipe 40 presses in end cap 12, reduces welding, while overall structure is equivalent to there is one " beam " to connect whole vapour liquid separator
The structure of the inside, fixed plate 60 strengthen the intensity of " beam ", and " beam " possesses the work(of vapour liquid separator while increasing resistance to vibration
Energy.
During work, gas enters the inside of vapour liquid separator by the import 122 of vapour liquid separator, and gas first is beaten
On swash plate 20, certain liquid is removed, then gas is flowed out by the water conservancy diversion gap 70 between support tube 30 and escape pipe 40,
Return to compressor.The lower end of swash plate 20 is less than the upper surface of support tube 30, ensures in vapour liquid separator when automobile rocks
Waiting liquid can be stopped by swash plate 20.
The vapour liquid separator assemble flow of the present invention is as follows：Escape pipe 40, support tube 30, filter 50 and fixed plate first
60 are integrally formed well (as shown in Figure 7) by interference fit, then by the outward flange 41 of escape pipe 40 in the integrative-structure
Swash plate 20 is withstood on to the lower surface of end cap 12, one component of composition is tightened up by pressing, finally by the component and shell
10 assemble up and are connected (as shown in Figure 1) by argon arc welding.
According to another aspect of the present invention, there is provided a kind of compressor, including vapour liquid separator, vapour liquid separator are above-mentioned
Vapour liquid separator in embodiment.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
Conventional U-shaped escape pipe is changed to escape pipe and adds the form of support tube by the present invention, and possesses vapor-liquid separation function.
Its resistance to vibration, the better than ever U form of tubes of resistance to vibration are strengthened by the change of outlet duct structures form.Cancel air inlet pipe, and increase
Adding with gradient swash plate, prevents liquid from flowing directly into escape pipe and avoids the situation of absorbing gas belt liquid from occurring.
The present invention optimizes the pipeline inside vapour liquid separator and the structure of swash plate, improves vapour liquid separator
Resistance to vibration, meet the vibration requirement using high pressure refrigerant air-conditioning system and automobile.Structure is easily facilitated installation simultaneously, reduce
The welding of pipeline, shell is avoided to cause the decline of its mechanical property by high temperature electric welding.
The preferred embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
