It is worth.
Seeing Fig. 2, unloader 11 includes valve body 111, is provided with valve pocket 117, valve body 111 offers and valve in valve body 111
The coolant import 113 of chamber 117 connection and refrigerant exit 114, be provided with spool 112 in valve pocket 117, spool 112 can be sliding along valve pocket 117
Dynamic, spool 112 slides along direction and offers refrigerant channel 118, the one end open of refrigerant channel 118, and the other end is closed, and cold
The opening of matchmaker's runner 118 is relative with coolant import 113, is provided with spring 115, spring between the inwall of spool 112 and valve pocket 117
115 along spool 112 glide direction arrange, the sidewall of refrigerant channel 118 offers unloading hole 1121.Compare shown in Fig. 1 existing
Unloading valve used for Air Conditioners, the unloader 11 that the embodiment of the present invention provides has that part is few, simple in construction, low cost of manufacture, can
By property advantages of higher, it addition, its dismounting is also easier, greatly facilitates maintenance and change.
The operation principle of this unloader 11 is as follows: in air-conditioner work process, when the coolant pressure in coolant circulating system
During less than the first preset pressure, unloading hole 1121 disconnects with refrigerant exit 114, and unloader 11 is in normally closed state；Work as coolant
When coolant pressure in blood circulation is more than the first preset pressure, spool 112 overcomes spring 115 under the effect of coolant pressure
Elastic force slides along valve pocket 117, makes refrigerant channel 118 be connected, in refrigerant channel 118 by unloading hole 1121 with refrigerant exit 114
Coolant flow out from refrigerant exit 114 through unloading hole 1121, make coolant circulating system pressure release.
Open continually in order to avoid pressure control switch 121 controls coolant circulating system long-play in the case of a high temperature
Stopping, as shown in Figure 2, it is preferable that unloading hole 1121 is multiple, multiple unloading holes 1121 arrange along the glide direction of spool 112.By
In pressure control switch 121 only off and on, running under in hyperthermal environments, the pressure of coolant circulating system is often
Beyond the second preset pressure value, if being provided only with a unloading hole 1121 on the spool 112 of unloader 11, then unloading hole 1121
Can only carry out a pressure release, owing to the time of a pressure release is relatively short, the pressure of system will quickly rise above second
Preset pressure value, pressure control switch 121 controls coolant circulating system and quits work, and system pressure can be gradually lowered；Work as off-load
When the coolant pressure in the exit of valve 11 is less than the unlatching force value of pressure control switch 121, pressure control switch 121 will connect
Logical, coolant circulating system will be reworked, and coolant circulating system will frequently occur under the control of pressure control switch 121
Start-stop phenomenon, so can affect the refrigeration of indoor temperature, makes indoor comfort be deteriorated, therefore, by multiple unloading hole 1121 along valve
The glide direction arrangement of core 112, can open different unloading holes 1121, unloading hole according to coolant circulating system pressure size
1121 can pressure release successively, when system pressure higher than the second preset value time, pressure control switch 121 carries out pressure guarantor to system
Protect.Owing to the total time of the pressure release of multiple unloading holes 1121 is relatively long, system can be made with the rate of climb of relieving system pressure
Pressure greatly reduces higher than the number of times of the second preset pressure value, solves coolant circulating system long-play in the case of a high temperature frequency
The problem of numerous ground start-stop, thus improve the comfort level of indoor.
It should be understood that the second preset pressure value is not higher than system pressure maximum bearing value, pressure control switch 121
Open force value and be not higher than the first preset pressure value.
The process of multiple unloading hole 1121 pressure releases successively is following (as a example by 3 unloading holes): set coolant circulating system room temperature
Under (outdoor environment temperature is 35 DEG C) force value be P, now unloader 11 is in normally off, as it is shown on figure 3, work as system pressure
When reaching P+0.5MPa, the spool 112 of unloader 11 goes out along valve pocket 117 upward sliding, upper unloading hole with the coolant of unloader 11
Mouth 114 connection, upper unloading hole carries out pressure release to system；As shown in Figure 4, when system pressure reaches P+1.0MPa, unloader 11
Spool 112 connect along valve pocket 117 upward sliding, upper unloading hole, middle unloading hole with unloader 11 refrigerant exit 114, upper off-load
Hole, middle unloading hole carry out pressure release to system；As it is shown in figure 5, when system pressure reaches P+1.5MPa, unloader 11 spool 112
Along valve pocket 117 upward sliding, upper unloading hole, middle unloading hole, lower unloading hole connect with the refrigerant exit 114 of unloader 11, above unload
Lotus hole, middle unloading hole, lower unloading hole carry out pressure release to system；As it is shown in figure 5, when system pressure is more than P+2.0MPa, pressure
Control switch 121 control systems to quit work.
It should be understood that each force value during multiple unloading hole 1121 pressure releases successively is for the ease of understanding
The hypothesis value of this process, is not the restriction to practical situation force value, and each force value can be reasonable according to practical situation
Arrange.
Wherein, the number of unloading hole 1121 is unsuitable too much, and too much unloading hole 1121 can make the spool 112 of unloader 11
Intensity reduces, and is easier to damage, it addition, the manufacturing process that too much unloading hole 1121 also can make spool 112 is complicated, improves
The manufacturing cost of unloader 11, therefore, on the premise of satisfied design requires, unloading hole 1121 is preferably 3.
Seeing Fig. 2, pressure transducer 122 connects with refrigerant exit 114.If pressure transducer 122 is with refrigerant inlet even
Logical, now pressure transducer 122 records the pressure making unloader 11 refrigerant inlet, when causing pressure in system for a certain reason
During abruptly above the second preset pressure, before the spool 112 of unloader 11 so can be made to have not enough time to action pressure release, Stress control is opened
Pass 121 will control coolant circulating system and quit work.Therefore, pressure transducer 122 is connected with refrigerant exit 114, permissible
Avoid the generation of above-mentioned phenomenon.Coolant at refrigerant exit 114 can pass through coolant flow orifice 119 and pressure transducer 122 phase
Contact, the system pressure after at this moment pressure transducer 122 can measure unloader 11 pressure release accurately, in order to unloader 11,
The pressure of system is protected by pressure control switch 121.
See Fig. 2, in order to limit unloader 11 downward sliding of spool 112 when normally off, it is preferable that valve pocket
Being provided with limited block 116 in 117, when the coolant pressure in coolant circulating system is less than the first preset pressure, spool 112 is away from bullet
One end of spring 115 and limited block 116 against.Owing to being provided with spring 115 between the inwall of spool 112 and valve pocket 117, when in off-load
During valve 11 normally off, when i.e. the coolant pressure in coolant circulating system is less than the first preset pressure, spool 112 is at spring 115
Under the effect of elastic force, can be along valve pocket 117 slide downward, if not setting limited block 116, spool 112 likely skids off valve pocket 117,
In order to avoid the generation of this situation, in valve pocket 117, it is provided with limited block 116, when unloader 11 normally off, limited block 116
Limit spool 112 valve pocket 117 slide downward by leaning away from one end of spring 115 with spool 112, make unloader 11 energy
Enough normal work.
