Abstract
The utility model relates to liquid slugging preventive devices for compressors, in particular to an automatically-closed liquid slugging preventive device for an air-cooled heat pump air-conditioner, which comprises an air-liquid separator, a transverse rod, a rope, a floating ball, a vertical rod, a valve core, a hinge, an output pipe, an input pipe, a compressor exhaust pipe and a compressor. The compressor is sequentially connected with a condenser, a throttle valve, an evaporator and the air-liquid separator in a closed loop manner, the hinge is fixedly mounted at the bottom of the inner side wall of the air-liquid separator, one end of the transverse rod is connected onto the hinge, and the other end of the transverse rod is connected with the floating ball through the rope. The automatically-closed liquid slugging preventive device for the air-cooled heat pump air-conditioner has the advantages that the input pipe is closed when liquid in the air-liquid separator is excessive, so that liquid refrigerant can be prevented from being sucked into the compressor to result in liquid slugging; the size of the air-liquid separator is reduced, and accordingly manufacturing materials and space are saved; and the device is simple in mounting and easy in production and operation.
Description
Technical field
The utility model relates to the anti-liquid hammer device of compressor, and especially a kind of air-cooled heat pump air-conditioning self closing is prevented the liquid hammer device.
Background technology
Existing air-cooled heat pump air-conditioning system heats in the work in the winter time, because outdoor environment temperature is low, the heating capacity decay is very big, has often satisfied not the requirement of air-conditioning thermic load, and indoor air temperature in air conditioned building reduces, degree of comfort decreased.At this moment; The air-cooled heat pump air-conditioning system can increase the pressure of refrigeration system condenser, reduces the pressure of evaporimeter, makes whole refrigeration system many when needing cold-producing medium than refrigeration when heating; When working conditions change; Having does not have the evaporated liquid cold-producing medium to get back to compressor and be compressed, because the incompressible characteristic of liquid, with " liquid hammer " fault that causes compressor.In order to prevent " liquid hammer ", present air-cooled heat pump air-conditioning system, at the bigger gas-liquid separator of compressor air suction mouth installation volume, this improper increase cost, and take up space.
Summary of the invention
The purpose of the utility model is to overcome defective of the prior art; Adopt a kind of air-cooled heat pump air-conditioning self closing to prevent the liquid hammer device, close input pipe when liquid is too much in gas-liquid separator, prevent that liquid refrigerant is inhaled into compressor and causes liquid hammer; Easy operating is installed simply.
For realizing above-mentioned purpose; The technical scheme of the utility model is to adopt the anti-liquid hammer device of a kind of air-cooled heat pump air-conditioning self closing; Comprise gas-liquid separator, cross bar, rope, ball float, vertical rod, spool, hinge, efferent duct, input pipe, compressor exhaust pipe, compressor; Described compressor is connected with condenser, choke valve, evaporimeter, gas-liquid separator closed loop successively; The madial wall bottom of described gas-liquid separator has fixedly mounted hinge, and described cross bar one end is connected on the hinge, and the other end connects ball float through rope.
Described vertical rod one end is fixedly connected on the cross bar, and the other end is fixedly connected spool.
Described ball float is processed by lightweight foamed plastics or filling with inert gas balloon.
The basic principle of the utility model: after using the utility model, the liquid refrigerant that flows to gas-liquid separator is many, and refrigerant level raises; Ball float rises and drives upwards operation of spool; Turn down the mouth of pipe of input pipe, the liquid refrigerant of input reduces, the liquid level of control gas-liquid separator; Do not allow compressor from efferent duct inhalant liquid cryogen, effectively prevent compressor liquid hammer fault.
The beneficial effect of the utility model is:
(1) when liquid is too much in the gas-liquid separator, closes input pipe, prevent that liquid refrigerant is inhaled into compressor and causes liquid hammer.
(2) reduce the size of gas-liquid separator, save the material of making, save the space.
(3) install simply, be easy to production operation.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Fig. 2 is the use sketch map of the utility model.
Among the figure: 1, gas-liquid separator 2, cross bar 3, rope 4, ball float 5, vertical rod 6, spool 7, hinge 8, efferent duct 9, input pipe 10, compressor exhaust pipe 11, compressor.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2 the utility model specific embodiment is further described:
The technical scheme that provides according to the utility model; A kind of air-cooled heat pump air-conditioning self closing is prevented the liquid hammer device; Comprise gas-liquid separator 1, cross bar 2, rope 3, ball float 4, vertical rod 5, spool 6, hinge 7, efferent duct 8, input pipe 9, compressor exhaust pipe 10, compressor 11; Described compressor 11 is connected with condenser, choke valve, evaporimeter, gas-liquid separator 1 closed loop successively; The madial wall bottom fixed installation hinge 8 of described gas-liquid separator 1, an end of described cross bar 2 is connected on the hinge 8, and the other end connects ball float 5 through rope 3.
Described vertical rod 5 one ends are fixedly connected on the cross bar 2, and the other end is fixedly connected spool 6.
Described ball float 4 is processed by lightweight foamed plastics or filling with inert gas balloon.
The course of work of the utility model is: in the refrigeration system of air-cooled heat pump air-conditioning, compressor 11 is connected with condenser, choke valve, evaporimeter, gas-liquid separator 1 closed loop successively, behind use the utility model; When the air-cooled heat pump air-conditioning system heated under low temperature environment, the cold-producing medium in evaporimeter can not evaporate fully, had increased the liquid refrigerant that flows to gas-liquid separator 1; Refrigerant level raises, and ball float 4 rises and drives upwards operation of spool 6, turns down the mouth of pipe of input pipe 9; The liquid refrigerant of input reduces; Compressor 11 constantly from gas-liquid separator 1 sucking-off refrigerant gas side by side to condenser, the liquid level of gas-liquid separator 1 is descended, ball float 4 descends; Spool 6 is also descending, opens the mouth of pipe of the input pipe 9 of big gas-liquid separator 1.The aperture of the mouth of pipe through regulating input pipe 9, the liquid level of cold-producing medium does not allow compressor 11 from efferent duct 8 inhalant liquid cryogens in the control gas-liquid separator 1, effectively prevents compressor 11 liquid hammer faults.
The advantage of present embodiment is, when liquid is too much in the gas-liquid separator 1, closes input pipe 9, prevents that liquid refrigerant is inhaled into compressor 11 and causes liquid hammer; Reduce the size of gas-liquid separator 1, save the material of making, save the space; Install simply, be easy to production operation.
