The specific embodiment
Describe the specific embodiment of the present invention in detail with specific embodiment below.
Fig. 1 is the schematic diagram that the short tube type choke valve of a kind of embodiment of the utility model is shown.As shown in Figure 1, this short tube type choke valve comprises body 1 and first spool 2, second spool 4 and the stop part 3 be located in the body 1.First spool 2 is cylindrical, and is provided with the axially extended helical groove 22 of spirality along its periphery.Second spool 4 also is cylindrical, and with the first spool 2 reservation distance of being separated by, second spool 4 also is provided with along the axially extended helical groove 44 of periphery spirality, and a centre bore 42 that axially runs through second spool.Above-mentioned helical groove all can be communicated with the two ends of corresponding spool.
This choke valve also comprises stop part 3, and it is arranged between first spool 2 and second spool 4 movably, and stop part 3 comprises that one can seal the truncated cone shape termination 32 of centre bore 42 of second spool 4 and at least one the linear groove 34 that is provided with along side face.The shape of this groove 34 also can be waveform or spirality.
In short tube type choke valve shown in Figure 1, also further comprise the screen pack 5 of being located at two ends.In addition, first spool 2, second spool 4 and screen pack 5 are spacing by the necking down of being located in the body 17.
In the above-described embodiment, when air-conditioning equipment is heating state when work, refrigerant enters choke valve from left end, promotes stop part 3 and moves to second spool 4 and seal its centre bore 44.At this moment, refrigerant the flow through helical groove 22 of first spool, the groove 34 of stop part 3 and the helical groove 44 of second spool flow out from right-hand member then.When air-conditioning equipment when refrigerating state is worked, refrigerant enters stop valve from right-hand member, promotes stop part 3 and leaves second spool 4, and open centre bore 44.At this moment, refrigerant successively the flow through centre bore 44 of second spool, the groove 34 of stop part 3 and the helical groove 22 of first spool flow out from left end then.
Fig. 2 is the schematic diagram that the short tube type choke valve of the another kind of embodiment of the utility model is shown.The difference of it and Fig. 1 is that second spool 4 is provided with near first spools 2, and stop part 3 towards also therefore putting upside down, so that cooperate with second spool.For the limit stop part to can moving by far-end, in the end opposite of second spool 4 ring-shaped valve seats 6 is set.As an alternative, this valve seat can be replaced by 1 one sections of dwindling of body.The operation principle of this valve when freezing and heating also is readily appreciated that, no longer repeats at this.
Can do multiple variation to the cross sectional shape of stop part 3, prerequisite is to keep at least one groove between the periphery of stop part 3 and body 1 inwall.Fig. 3 A and Fig. 3 B illustrate the block piece 3 of two kinds of cross sectional shapes respectively.These cross sections all comprise and are used to contact the contact portion 3a of body 1 inwall and the sunk part 3b that does not contact with body 1 inwall.These sunk parts cooperate the formation groove with body just.
As a kind of optimal way (referring to Fig. 4), can be in position corresponding to block piece 3 activities, some bulge-structures or salient point 11 are set on body 1 inwall, these bulge-structures or salient point are used at least one described contact portion 3a of backstop block piece, be used for limit stop part 3 rotation in body under the effect of high speed swirling eddy, to reach the purpose that reduces friction, reduces noise.Certainly, these bulge-structures also can be arranged on the end face that is used for contactor banking stop spare 3 of valve seat 6.
When joining the flow air-conditioning equipment of different requirements, can short-tube restrictor valve flow be met the demands by regulating the big or small of groove sectional area or changing helix pitch adjustable screw line length.Spiral spool groove can be processed into: shape such as square, semicircle, triangle, T shape.
More than by two embodiment the structure of bidirectional modulation choke valve of the present utility model has been described.By this choke valve, in refrigeration, required flow difference in the system when heating, different throttling flows can be realized in the bidirectional throttling valve two ends, makes system in refrigeration, the operating mode ability meets the demands when heating.
Although the utility model is illustrated with reference to accompanying drawing and preferred embodiment, but obviously, for a person skilled in the art, under the prerequisite that does not deviate from spirit and scope of the present utility model, can make some changes and variation to the utility model fully.Therefore, various change of the present utility model, the content that changes by appending claims and equivalent thereof contain.
