As shown in Figure 3, spool placed cavity 8 separates formation by four dividing plates 12 being radiation dress distributing in housing 6, and the top margin of dividing plate 12 and side are all closely connected with the inwall of housing 6, and the bottom of dividing plate 12 is fixed on the outer wall of hybrid chamber 11 and intermediate cavity 14.
As shown in Figure 4, the structure of spool placed cavity 8 and spool 9, at spool 9 of the interior placement of each spool placed cavity 8, on spool 9, there is a through hole running through 10, the diameter of through hole 10 is the aperture of internal diameter or the expansion throttling valve of throttle capillary tube, the shape of spool placed cavity 8 is roughly Y-shaped, the contour structures of spool 9 is also roughly Y shape, spool 9 coordinates with spool placed cavity 8 can shutoff spool placed cavity 8, the company's of cut-out machine pipe 3, also can leave from the slot of spool placed cavity 8, be communicated with and connect machine pipe 3.
Describe the course of work of this frock below in detail:
1,, before installation, first estimate the specification of four spools 9.
When 2, indoor unit and outdoor unit is online, four spools 9 are installed on respectively in 1-4 spool placed cavity 8.
3, two throttle valve components 5 that install spool 9 are serially connected with on tube connector 3, spool 9 installation directions in two throttle valve components 5 are relative.
4, after online completing, be pulled outwardly topping bar 15, make to come directly towards 16 connected entrances that stagger on hybrid chamber 11, and then four spool placed cavities 8 are communicated with hybrid chamber 11.
5, indoor set 1, off-premises station 2, company's machine pipe 3 are vacuumized, now, 1-4 spool placed cavity 8 and hybrid chamber 11 are all in vacuum state.
6, taken out after vacuum, dose refrigerant, make indoor set 1, machine pipe 3,1-4 spool placed cavity 8 all be filled with refrigerant with hybrid chamber 11, at this moment push rod 15 is advanced to the inside, make to come directly towards four connected entrances of 16 cut-out, 4 spool placed cavities 8 are kept apart mutually, now, only have No. 1 spool placed cavity 8 and connect machine pipe 3 and be connected, other 8 of 3 spool placed cavities are temporarily kept apart and are included refrigerant.
7, debugging test is carried out in air-conditioner operation, during refrigerating operaton, first refrigerant enters in the throttle valve component 5 in left side from off-premises station 2, company's machine pipe 3, spool 9 in No. 1 spool placed cavity 8 in the throttle valve component 5 of left side moves to the right under the motive force effect of refrigerant, remove the slot of spool placed cavity 8, make to flow through the space of refrigerant between spool 9 and spool placed cavity 8, refrigerant is not carried out to throttling.Now, the spool 9 in No. 1 spool placed cavity 8 in the throttle valve component 5 on right side moves to the right under the motive force effect of refrigerant, and the slot of shutoff spool placed cavity 8 can only flow through refrigerant, and then refrigerant is carried out to throttling from the through hole 10 of spool 9.
During heating operation, just in time contrary with said process.
If 8 have demand to adjust the spool 9 of another kind of specification, take intermediate cavity 14 and hybrid chamber 11 as axle center rotary spool placed cavity 8, make another spool placed cavity 8 and connect machine pipe 3 and is communicated with, can realize and not shut down replacing spool 9, and not need emptying.
