Description
Technical field
The utility model relates to technical field of refrigeration equipment, in particular to a kind of refrigeration air-conditioner throttling set.
Background technique
The throttling set of existing list refrigeration air-conditioner is the capillary module that the multistage copper pipe with different-diameter is welded,
The outlet of one end and condenser, the other end are connected through copper pipe with shut-off valve.Compressor, condenser, capillary module, copper
Pipe is respectively positioned in the cabinet of air-conditioner outdoor unit, and shut-off valve is threaded on the outside of the cabinet of air-conditioner outdoor unit through pedestal.Shut-off valve
Outlet be connected through connecting tube with the evaporator of air conditioner indoor unit.
When air conditioner refrigerating, the steam that gas coolant is compressed by the compressor as high temperature and pressure, refrigerant cooling is put after condenser
Heat, as the liquid coolant of normal temperature high voltage.Liquid coolant becomes low temperature and low pressure liquid after capillary module decompression throttling, then leads to
Cross the evaporator that copper pipe, shut-off valve, connecting tube enter the room machine.
However, since the resistance of capillary module is very big, and refrigerant is in capillary module in existing list refrigeration air-conditioner
Forward and reverse flow suffered resistance be it is the same, when filling refrigerant from shut-off valve end, can add because of the hydraulic force reasons such as not enough
The speed of liquid is very slow, or even is unable to liquid feeding.Therefore, also tending to design on the outdoor unit of existing single refrigeration air-conditioner has individual liquid feeding
The outlet of process duct, liquid-feeding technical pipe and condenser is connected.By liquid-feeding technical pipe fill refrigerant after, then with weld mode
The nozzle of liquid-feeding technical pipe is sealed.
In addition, often there is the problems such as flat copper pipe or weldering leakage in process of production in liquid-feeding technical pipe, it is empty in order to promote quality
Adjust producer that can only increase copper pipe thickness, this causes the cost of air-conditioning products to improve again.
Utility model content
In view of the above drawbacks of the prior art, it is empty that the technical problem to be solved by the utility model is to provide a kind of refrigeration
Throttling set is adjusted, this throttling set resistance in refrigerant reverse flow is smaller, without adding liquid-feeding technical pipe.
To achieve the above object, the utility model provides a kind of refrigeration air-conditioner throttling set, including valve body, in the valve body
There is columned valve chamber and is connected to valve chamber both ends and feed pathway and liquid outlet channel of the diameter less than valve chamber diameter, the valve
It is intracavitary radially slide be provided with spool, the spool includes the pedestal that diameter is adapted with valve chamber and is connected to pedestal and leans on
The seal head that nearly liquid outlet channel one end and diameter and liquid outlet channel are adapted, have in the spool with close to its liquid outlet channel one end
The throttling chamber of perforation, the sealing cephalic par have the throttling pore with throttling chamber perforation；If being provided on the side wall of the seal head
Dry for the first fill orifice for coolant media reverse circulated.
The above structure, when coolant media forward flow, coolant media pushes spool mobile to liquid outlet channel, seal head into
Enter into liquid outlet channel, the first fill orifice is sealed, and coolant media can only be flow in liquid outlet channel by the pore that throttles, and reaches section
The effect of stream；When coolant media is perfused, coolant media adverse current, coolant media pushes spool to move into feed pathway side, close
End socket enters in valve chamber, and the first fill orifice is opened, and coolant media passes through liquid outlet channel, valve chamber, the first fill orifice, throttling chamber stream
To feed pathway.
Preferably, having on the valve chamber inner wall prolongs the guide-track groove of its axial direction extension, the pedestal lateral surface setting
Guide rail, the guide rail are slidably seated in guide-track groove.Guide rail band movable valve plug effectively prevent spool to turn in predetermined party slid inward
It is dynamic that poorly sealed phenomenon is caused to occur.
Preferably, the end of the seal head is hemispherical configuration.Through this structure, mobile to feed pathway side in spool
When, seal head can smoothly enter in liquid outlet channel.
Preferably, the intracavitary diameter of throttling is less than feed pathway internal diameter and is greater than throttling pore internal diameter.It is cold when forward flow
Medium first passes around throttling chamber and passes through throttling pore again, and certain buffering is carried out to coolant media by throttling chamber.
Preferably, the valve chamber inner wall be provided with several be located on body wall and be bent extension passed through with feed pathway cavity
Logical perfusion channel, it is described throttling chamber side wall on have with valve body outside penetrate through and with perfusion channel be adapted the second fill orifice, when
When the pedestal is against feed pathway end close to one end of feed pathway, the perforation of both the second fill orifice and perfusion channel.When
When coolant media adverse current, coolant media can also be flow in feed pathway by throttling chamber, the second fill orifice and perfusion channel, be increased
The big inflow-rate of water turbine of coolant media, further reduces overcurrent resistance.
Preferably, second fill orifice is intracavitary outward towards the inclination of feed pathway side from throttling.Through this structure, so that
Coolant media is more smoothly flowed into the second fill orifice, further reduces overcurrent resistance.
The beneficial effects of the utility model are: this throttling set both plays throttling action, cold media can also reversely be perfused
Matter, resistance is smaller when refrigerant reverse flow, without individually adding liquid-feeding technical pipe.
