Embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Fig. 1 shows the structural representation according to the embodiment of four-way valve of the present utility model, and as can be seen from the figure, the four-way valve of the present embodiment comprises main valve body 10 and a plurality of connecting tube.Wherein, in main valve body 10, be provided with valve chamber, be provided with spool in valve chamber, spool is separated out the first separate valve chamber and the second valve chamber by the two ends of valve chamber.Spool comprises slide block 22, and slide block 22 movably is arranged in valve chamber.A plurality of connecting tubes all are communicated with main valve body 10, connecting tube comprises along main valve body 10 axial directions and is successively set on E connecting tube 11, S connecting tube 12 and the C connecting tube 13 on main valve body 10, and be connected to D connecting tube 14 on main valve body 10 and that be oppositely arranged with S connecting tube 12, in the longitudinal section through the axis of main valve body, the inwall away from C connecting tube 13 of E connecting tube 11 and C connecting tube 13 away from forming tube pitch L2 between the inwall of E connecting tube 11.The length L 1 of slide block 22 and the ratio range of tube pitch L2 are between 0.95 to 0.99.
The ratio of the length L 1 of the slide block 22 in four-way valve and tube pitch L2 is arranged between 0.95 to 0.99, in the time of can avoiding slide block 22 to be commutated, block at one time E connecting tube 11, S connecting tube 12 and C connecting tube 13 fully, there do not is the sealing dead point when slide block 22 commutation, thereby avoid the slide block to there will be the problem of sealing dead point in movement process, and then reduced the impact to all parts in the movement process of slide block of liquid in valve body.Simultaneously, the length L 1 of slide block 22 and the ratio of tube pitch L2, between 0.95 to 0.99, can make four-way valve in the situation that have certain amount of leakage and can have enough pressure differences to guarantee the normal commutation of four-way valve.Preferably, the ratio of the length L 1 of slide block 22 and tube pitch L2 is 0.97.
In the present embodiment, as shown in Figure 2 and Figure 4, slide block 22 has is communicated with E connecting tube 11 and S connecting tube 12 and the second place that C connecting tube 13 and D connecting tube 14 are communicated with, and make between S connecting tube 12 and C connecting tube 13 to be communicated with and E connecting tube 11 and D connecting tube 14 between the 3rd position that is communicated with.Slide block 22 is realized refrigeration in the second place, in the 3rd position, realizes heating.Slide block 22 also has the primary importance between the second place and the 3rd position.As shown in Figure 3, when slide block 22 is positioned at primary importance, E connecting tube 11 and C connecting tube 13 all are communicated with S connecting tube 12 and E connecting tube 11 and C connecting tube 13 all are communicated with D connecting tube 14.Because E connecting tube 11 and C connecting tube 13 all are communicated with D connecting tube 14, slide block 22 not there will be the sealing dead point in running, and in the commutation process of slide block 22, D connecting tube 14 at least is communicated with in E connecting tube 11 and C connecting tube 13 one.Such setting, in the process commutated at slide block 22, slide block 22 all the time with E connecting tube 11 or C connecting tube 13 in one have gap, this gap makes hyperbaric chamber be communicated with in E connecting tube 11 or C connecting tube 13 one in the movement process of slide block 22, thereby the internal pressure of balance four-way valve self, be reduced in the pressure peak in the hyperbaric chamber in slide block 22 commutation processes, and then reduce the possibility of generating liquid impact fault.
Spool in the present embodiment comprises valve seat, slide block 22, support 23 and the piston 24 that is arranged on support 23 two ends, and spool is separated out the first separate valve chamber and the second valve chamber by piston 24 by the two ends of valve chamber.Wherein.Valve seat is arranged in valve chamber and is fixed on main valve body 10, and slide block 22 can be slided along valve seat.Be provided with three attachment holes on valve seat, slide block 22 is connected with support 23 and is slidably disposed on the upper end surface of attachment hole.Three attachment holes are communicated with respectively with between E connecting tube 11, S connecting tube 12 and C connecting tube 13 correspondingly.Offer connectivity slot on slide block 22, when slide block 22 is positioned at the second place, connectivity slot is communicated with E connecting tube 11 and S connecting tube 12.When slide block 22 is positioned at the 3rd position, connectivity slot is communicated with S connecting tube 12 and C connecting tube 13.The conversion of the position of the slide block 22 in the present embodiment can be regulated by changing the indoor pressure difference of the first valve chamber and second valve, relates to the indoor structure of four-way valve and working principle, very common in related domain, at this, does not too much repeat.
As shown in Figures 2 to 4, the four-way valve of the present embodiment also is connected with pilot valve in use, pilot valve comprises guide valve blocks, the 4th connecting tube that is disposed with the first connecting tube, the second connecting tube and the 3rd connecting tube and is oppositely arranged with the second connecting tube along its axial direction on guide valve blocks.Be provided with the pilot valve slide block in guide valve blocks, the pilot valve slide block has the 4th position and the 5th position, and the pilot valve slide block is when the 4th position, and the first connecting tube and the second connecting tube are communicated with and the 3rd connecting tube and the connection of the 4th connecting tube.The pilot valve slide block is when the 5th position, and the first connecting tube and the 4th connecting tube are communicated with and the second connecting tube and the connection of the 3rd connecting tube.The motion of pilot valve slide block is driving mechanisms control by being connected with this pilot valve slider-actuated.
Have following annexation between pilot valve and four-way valve: the first connecting tube is communicated with the first valve chamber, and the 3rd connecting tube is communicated with the second valve chamber, and the second connecting tube is communicated with S connecting tube 12, and the 4th connecting tube is communicated with D connecting tube 14.Preferably, be provided with the first opening be communicated with the first valve chamber and the second opening be communicated with the second valve chamber on main valve body 10, the first connecting tube is communicated with the first valve chamber by the first opening, and the 3rd connecting tube is communicated with the second valve chamber by the second opening.
The mobile flow direction that can change medium four-way valve in of pilot valve slide block between the 4th position and the 5th position, and then change the first valve chamber and the indoor pressure state of second valve, thereby realize the adjusting of the first valve chamber and the indoor pressure difference of second valve is reached to the regulating action realized the position of the slide block 22 in four-way valve.
The utility model also provides a kind of air conditioner, according to the embodiment of air conditioner of the present utility model, comprises four-way valve, and this four-way valve is above-mentioned four-way valve.Owing to thering is above-mentioned four-way valve, can reduce liquid hammer and impact, and then extend the working life of air conditioner.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
