Detailed description of the invention:

In order to be better understood from and implement, provide embodiment below in conjunction with the accompanying drawings and describe in detail；Illustrated embodiment is only used for explaining the utility model, is not intended to limit protection domain of the present utility model.

Embodiment 1, see Fig. 1,2, need to be processed into valve body 12 and spool 14 according to design, valve body 12 inwall offer crater or hole；Have upper cover 11 on valve body, under have lower cover 13, valve body 12 sidewall is uniformly offered six passages of A, B, C, D, E, F the 1st, the 2nd, the 3rd, the 4th, the 5th, 6；Spool 14 cross section is Y shape, and fan-shaped positioning ring groove 19 is offered in spool 14 bottom；Spool 14 is installed inside valve body 12, is contained in positioning ring groove 19 equipped with stop screw 18, screw 18 top at lower cover 13 upper surface；Spool 14 is middle porose, and equipped with valve rod 15, valve rod 15 is connected with spool 14, it is possible to driven by valve rod 15, in the blind hole be contained in valve rod 15 lower end in lower cover 13；Upper cover 11 upper surface is prominent forms boss, there is through hole centre, and the middle and upper part of through hole is taper, valve rod 15 fills in through-holes, and equipped with hard seal 8 and soft seal 9 between through hole and valve rod 15, hard seal 8 is taper, it is sealed in the taper position of upper cover 11 through hole, being compressed by clamp nut 7 above, soft seal 9 is once sealing, and hard seal 8 is secondary seal；Valve rod 15 upper end is processed into square, passes through upper cover 11 and is exposed at outside upper cover 11 boss, installs driving head 17 on the top of valve rod 15；On upper cover 11 equipped with seal lid 16, seal lid 16 compression sealing gaskets 10, sealing gasket 10 be three times seal, formed to external seal.

During normal work, see Fig. 3, when Y-valve core 14 is in Fig. 3 position, A channel 1 and channel B 2 UNICOM, C-channel 3 and D passage 4 UNICOM, E passage 5 and F passage 6 UNICOM.

When by external rotating spool 60 °, spool is in Fig. 4 position, now channel B 2 and C-channel 3 UNICOM, D passage 4 and E passage 5 UNICOM, F passage 6 and A channel 1 UNICOM.

Embodiment 2, sees Fig. 7, same to embodiment, is a difference in that, more flexible in order to make valve rotate, in valve rod 15 lower end equipped with bearing 20, bearing 20 outer ring is contained in the blind hole of lower cover 13.

Embodiment 3, sees Fig. 8, with embodiment 1, is a difference in that, offers crater or hole, without crater or hole on valve body 12 inwall on spool 14 inwall；Check valve is installed on E passage 5.

A kind of six-way valve described in the utility model, during work, sees Fig. 5, A channel and channel B UNICOM when wherein normally work, C-channel and D passage UNICOM, E passage and F passage UNICOM.Refrigerant is discharged by compressor 21, flows into channel B by A channel, then flows into condenser 22, condensed refrigerant enters in reservoir 23, throttles through expansion valve 24, flows into aluminium row's evaporimeter 25, refrigerant after evaporation flows into C-channel by D passage, subsequently into compressor 21.

E passage and F passage are because being connected to check valve 26, and by buffer brake, and by.

After valve core rotation 60 °, seeing Fig. 6, it is that compressor 21 is vented that fluid flows to, flow into F passage by A channel, entering aluminium row's evaporimeter 25, aluminium row's evaporimeter 25 is defrosted by high temperature and high pressure gas, then flows to D passage, enter check valve 21 through E passage, and check valve 21 is turned on by positive pressure, the refrigerant after defrosting enters condenser 22 by check valve 21, then enters compressor 21 air-breathing via C-channel again by channel B.After defrosting terminates, complete the circulation of refrigerant.
