Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Preferred embodiment one:
The open outer machine system of a kind of heat-reclamation multi-compressors of this preferred embodiment.As shown in Figure 1, this system includes coolant and adjusts tank 1, it is arranged on the pressure-detecting device 2 between liquid feeding end 11 and the drain side 12 of coolant adjustment tank 1, is arranged on coolant and adjusts the pressurizing valve 3 of tank 1 liquid feeding end 11, liquid feed valve 5, equalizing valve 6 and be arranged on the tapping valve 4 of coolant adjustment tank 1 drain side 12.
Pressure-detecting device 2 adjusts the force value between tank 1 liquid feeding end 11 and drain side 12 for detecting coolant, trend and/or scope according to coolant adjustment tank 1 force value change determine whether that valve body controls to lose efficacy, and can know that specifically which or which valve body controls inefficacy.
The concrete structure of pressure-detecting device 2 is not limit, and can accurately and timely measure coolant and adjust force value between tank 1 liquid feeding end 11 and drain side 12.Preferably, pressure-detecting device 2 includes fluid reservoir 21 and is arranged on the pressure transducer 22 at fluid reservoir 21 liquid outlet mouth place；It is equal that fluid reservoir 21 and coolant adjust pressure in tank 1.In this structure, detect trend and/or the scope of coolant adjustment tank 1 force value change by detecting the pressure in fluid reservoir 21.
The preferred attachment structure of each valve body is: pressurizing valve 3 one end is connected to oil eliminator 7, and the other end is connected to coolant and adjusts the pumping entrance end of tank 1.Coolant adjusts drain side 12 place two branch roads in parallel of tank 1, and every branch road is provided with a tapping valve 4.Wherein, the first branch road is connected between drain side 12 and the gas-liquid separator 8 that coolant adjusts tank 1, and the second branch road is connected to coolant and adjusts between tank 1 drain side 12 and outdoor heat exchanger 9.Preferably, the second branch road is provided with check valve 41 between tapping valve 4 and outdoor heat exchanger 9.Liquid feed valve 5 one end is connected to coolant and adjusts the liquid inlet end of tank 1, and the other end is connected to the throttling arrangement 91 of outdoor heat exchanger 9.Preferably, adjust at liquid feed valve 5 and coolant and be provided with check valve between the liquid inlet end of tank 1.Equalizing valve 6 is arranged between pumping entrance end and the gas-liquid separator 8 that coolant adjusts tank 1.
The outer machine system of heat-reclamation multi-compressors is in valve body abatement detecting method during discharge opeing process: in Fig. 1 shown in thick line, and coolant adjusts the pressurizing valve 3 of tank 1 and will open with tapping valve 4 simultaneously, pressurizing valve 3 connected system high-pressure side, tapping valve 4 connected system low-pressure end.Open pressurizing valve 3 makes discharge opeing process establish a bigger pressure reduction with tapping valve 4 simultaneously, is conducive to discharge opeing.After discharge opeing terminates, coolant adjusts coolant in tank 1 and discharges, and correspondingly, in fluid reservoir 2, pressure is obviously reduced.Normal drainage under name heating condition, discharge opeing process pressure inside the tank maintains 2.0MPa, can maintain good discharge opeing.
When pressurizing valve 3 controls to lose efficacy, will be unable to set up an effective pressure differential (this pressure differential is pressure differential between pressure and low pressure in fluid reservoir 2) in fluid reservoir 2, in fluid reservoir 2, pressure can maintain low pressure maintenance value S1 gradually.Low pressure maintenance value S1 ranges between 0.4Mpa-0.8Mpa, it is preferred to 0.6Mpa.Now low pressure is 0.6MPa, so can cause that discharge opeing is more and more difficult.
When occurring in this process that tapping valve 4 controls to lose efficacy, then coolant adjusts coolant only import but no export in tank 1, and correspondingly in fluid reservoir 2, pressure will be gradually increasing.
When pressurizing valve 3 all controls to lose efficacy with tapping valve 4, then in fluid reservoir 2, coolant quantity will not change, and it is constant that pressure will be maintained at force value corresponding to ambient temperature.
Preferred embodiment two:
This preferred embodiment discloses the outer machine system of a kind of heat-reclamation multi-compressors and the valve body abatement detecting method based on this system.The outer machine system of this heat-reclamation multi-compressors is identical with preferred embodiment one, the outer machine system of heat-reclamation multi-compressors is in valve body abatement detecting method during feed liquor process: in Fig. 2 shown in thick line, coolant adjusts the liquid feed valve 5 of tank 1 and will open with equalizing valve 6 simultaneously, wherein, liquid feed valve 5 is communicated to system high pressure end, equalizing valve 6 is communicated to system low-voltage end, opens liquid feed valve 5 simultaneously and makes feed liquor process set up a bigger pressure reduction with equalizing valve 6, is conducive to feed liquor.After feed liquor terminates, coolant enters coolant and adjusts in tank 1, and in fluid reservoir 2, pressure can substantially increase.Normal feed liquor under name heating condition, feed liquor process pressure inside the tank can maintain 0.95MPa, can maintain good feed liquor.
When equalizing valve 6 controls under failure conditions, will be unable to set up an effective pressure differential (this pressure differential is the pressure differential between high pressure and pressure inside the tank) in fluid reservoir 2, in fluid reservoir 2, pressure can maintain high pressure maintenance value S2 gradually.High pressure maintenance value S2 ranges for 2Mpa-2.8Mpa, it is preferred that high pressure maintenance value S2 is 2.4Mpa.Now high pressure is 2.4MPa, so can cause that feed liquor is more and more difficult.
When occurring in this process that liquid feed valve 5 controls to lose efficacy, then coolant adjusts coolant in tank 1 will not increase, and in fluid reservoir 2, to maintain low pressure value gradually constant for pressure.
When equalizing valve 6 all controls to lose efficacy with liquid feed valve 5, then in fluid reservoir 2, coolant quantity will not change, and it is constant that pressure maintains force value corresponding to ambient temperature.
Note, above are only preferred embodiment of the present utility model and the know-why used.It will be appreciated by those skilled in the art that this utility model is not limited to specific embodiment described here, various obvious change can be carried out for a person skilled in the art, readjust and substitute without departing from protection domain of the present utility model.Therefore, although this utility model being described in further detail by above example, but this utility model is not limited only to above example, when conceiving without departing from this utility model, other Equivalent embodiments more can also be included, and scope of the present utility model is determined by appended right.
