Using Fig. 1, Fig. 2 shows alternative embodiment, by the first port 31 of escape pipe 3 to liquid storage device bottom bend, and
Anti-liquid impact device is set thereunder, which is utilized buoyancy, and when refrigerant liquid level is in low level, floating ball 51 is with liquid
Face is in low level, and liquid refrigerant sinks after filter 6 at this time, sinks to liquid storage device lower part, and gaseous refrigerant passes through first
Liquid storage device is flowed out through escape pipe 3 and enters compressor in port 31；When liquid refrigerant is more, is in high liquid level, floating ball 51 is floating
The top that floating ball casing 52 is risen under power effect, blocks first port 31, liquid refrigerant can not pass through first port at this time
31 enter escape pipe 3, to prevent the generation of liquid hit phenomenon.
Fig. 3 is that a kind of normal outlet status architecture of the liquid receiver for compressor shown according to another exemplary embodiment shows
It is intended to
As shown in figure 3, a kind of liquid receiver for compressor, including the shell 1 with air inlet pipe 2 and escape pipe 3, the shell 1
Inside includes the liquid storage space 4 for storing liquid refrigerant, which is characterized in that the first port 31 of the escape pipe 3 is to liquid storage
The bottom bend of device；Anti-liquid impact device is arranged in the lower section of the first port 31；It further include that the air inlet pipe 2 and the escape pipe 3 are set
Between filter 6, for filtering out liquid refrigerant and making it into the liquid storage space 4.
Optionally, which is equipped with filter opening 61, and the diameter of the filter opening 61 is 2~4mm.
In this way, gaseous refrigerant and liquid refrigerant are mixed with from the refrigerant that air inlet pipe 2 enters, in the present embodiment
In, when refrigerant is passed through from filter opening 61, liquid refrigerant falls directly into liquid storage space 4, or is first attached to the hole wall of filter opening 61, with
Liquid storage space 4 is instilled afterwards, and liquid refrigerant enters 4 bottom of liquid storage space, and after a period of time, liquid refrigerant volatilization is through the
Single port 31 enters escape pipe 3；Gaseous refrigerant pass through filter 6 after first flow downward, after flow up, through first port 31
It is discharged after into escape pipe 3.
Optionally, the middle part of the filter 6 is to close to the side of the air inlet pipe 2 protrusion.Optionally, the protrusion of filter 6
Shape be arc-shaped, the radius of circular arc is 30~50mm.As shown in figure 4, the filter area of filter 6 can be increased, reduce
Drag losses improve press efficiency.
Optionally, the first port 31 to the angular range of liquid storage device bottom bend be 100~180 degree.Can be 130,
150 or 180 degree.
Optionally, which includes floating ball 51, the floating ball casing 52 with 51 clearance fit of floating ball, which exists
It is slided up and down in floating ball casing 52；The floating ball casing 52 is equipped with multiple through-holes 53.
In this way, when the less liquid level of liquid refrigerant is in low level, floating ball 51 since gravity is at the middle part of buoyant spheres,
It is contour with liquid refrigerant liquid level；Liquid refrigerant sinks to liquid storage device lower part, gaseous refrigerant is by going out after filter 6
Tracheae 3 flows out liquid storage device and enters press；When the more liquid level of liquid refrigerant is in a high position, floating ball 51 is due in buoyancy meeting
It is raised to the top of floating ball casing 52, blocks gas outlet, liquid refrigerant is avoided and is flowed out by gas outlet, thoroughly prevented liquid hammer
Phenomenon.
Optionally, the diameter of the floating ball 51 is not less than the bore of the first port 31.In this way, refrigerant liquid level rises, float
When ball 51 floats up to first port 31, first port 31 can be blocked, prevents liquid refrigerant from entering.
Optionally, the diameter of the floating ball 51 is greater than the diameter of the through-hole 53.In this way, 53 energy of through-hole on the floating ball casing 52
Guarantee that floating ball 51 does not drop out.If the diameter of through-hole 53 is too small, it be easy to cause liquid level inside and outside floating ball casing 52 not contour, liquid impact prevention
The case where lag.
Optionally, which is the medicine ball that density is less than liquid refrigerant；Optionally, which is also possible to sky
Heart metal ball, optionally, the floating ball 51 are one of hollow aluminium ball, hollow copper ball or hollow stainless steel ball.According to liquid system
With it floating ball 51 chemically reacted, property is stable does not occur for cryogen, selection.In this way, floating ball 51 can be under buoyancy, in floating ball
It floats up and down in casing 52 with the liquid level height of liquid refrigerant.
Optionally, which is vertically arranged.In this way, reducing the occupancy to liquid storage space 4.
Optionally, which is equipped with Gask-O-Seal 32.In this way, blocking first port when floating ball 51 floats
When 31, leakproofness is improved, liquid refrigerant is further prevented to enter escape pipe 3.
Using the alternative embodiment shown in Fig. 3, setting hair filter 6, can make refrigerant when passing through in liquid storage device
Gas-liquid separation is carried out, liquid refrigerant falls into 4 bottom of liquid storage space, through first port 31 after volatilizing after a period of time for gaseous state
Into escape pipe 3；After gaseous refrigerant passes through filter 6, it is discharged after first port 31 enters escape pipe 3.It further prevents
The generation of liquid hit phenomenon.Anti-liquid impact device is set in the lower section of first port 31, which is utilized buoyancy, works as refrigeration
When agent liquid level is in low level, floating ball 51 is in low level with liquid level, and liquid refrigerant sinks after filter 6 at this time, sinks to storage
Liquid device lower part, gaseous refrigerant flow out liquid storage device through escape pipe 3 by first port 31 and enter compressor；When liquid refrigerant compared with
More, when being in high liquid level, floating ball 51 rises to the top of floating ball casing 52 under buoyancy, blocks first port 31, at this time
Liquid refrigerant can not enter escape pipe 3 by first port 31, to prevent the generation of liquid hit phenomenon.
