The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
As shown in Figure 1, be the structural representation of the utility model noise reduction bidirectional throttling valve embodiment.The noise reduction bidirectional throttling valve of present embodiment, comprise throttle body 1 in a tubular form, be provided with two valve seats 2 with its airtight cooperation in the throttle body 1, the slideway 4 that is provided with valve seat endoporus 3 in the valve seat 2 and communicates with valve seat endoporus 3, slideway 4 interior being slidingly matched with it are provided with spool 5, be provided with throttling spool hole 6 in the spool 5, slideway 4 is provided with the end conduction hole 7 that cooperates with spool 5 away from an end of valve seat 2 endoporus, and the position near valve seat endoporus 3 on the slideway 4 is provided with cross-current through hole 8, be provided with the ventilation annular groove 9 that communicates with cross-current through hole 8 between throttle body 1 and the valve seat 2, two valve seat 2 opposing ends are provided with the screen pack 10 for impurity screening, and the length of valve seat endoporus 3 is more than or equal to 1 times of its inner diameter d.
The noise reduction bidirectional throttling valve of present embodiment, length by valve seat endoporus 3 is set to more than or equal to its inner diameter d, when fluid is flowed through throttling spool hole 6 when entering valve seat endoporus 3, because the actual internal area in throttling spool hole 6 is less than the actual internal area of valve seat endoporus 3, the sudden change of actual internal area makes that fluid need be through keeping uniform fluidised form after one section disorder; Because the length of the valve seat endoporus 3 of existing bidirectional throttling valve is too short, causes fluid to enter filter 10 in the fluidised form of disorder, cause the cavitation erosion of filter 10 internal causes a large amount of bubbles to occur and break, noise is up to more than 70 decibels; And the length of the noise reduction bidirectional throttling valve of present embodiment by valve seat endoporus 3 is set to more than or equal to its inner diameter d, make fluid have the buffer distance of sufficient length, from valve seat endoporus 3 inflow filters the time, the fluidised form of fluid is even, can effectively alleviate cavitation erosion, and the reduction noise, and noise can be controlled below 55 decibels; Therefore, the noise reduction bidirectional throttling valve of present embodiment not only has low cost of manufacture, simple in structure and advantage that volume is little, but also can alleviate cavitation erosion, and reduces noise, improves comfort and increases the service life.
Preferably, the length of valve seat endoporus 3 is smaller or equal to 4 times of its inner diameter d, when the length of valve seat endoporus 3 during greater than 4 times of its inner diameter d, noise does not significantly descend, illustrate that air-flow has been tending towards even, and the length of valve seat endoporus 3 is set to smaller or equal to 4d, can effectively reduce the length of valve seat 2, and then reduce the volume of choke valve.Further, the length of valve seat endoporus 3 is 1.5d-3d, can further reduce noise, and with noise control below 55 decibels.Further, the length of valve seat endoporus 3 is 2d-3d, can be with noise control below 50 decibels, and can control the volume of choke valve by the length of control valve seat endoporus 3, reduce manufacturing cost.
Preferably, the diameter d of valve seat endoporus 3=3.2 ± 0.1mm, the length L of valve seat endoporus 3=6.5 ± 0.5mm, the diameter d=3.2mm of the valve seat endoporus 3 of present embodiment, the length L=6.4mm of valve seat endoporus is 2 times of valve seat endoporus 3 diameters, as shown in Figure 2.
As shown in Figure 3, as the diameter d=3.2 ± 0.1mm of valve seat endoporus 3, the length of valve seat endoporus 3 can also be L=10 ± 0.5mm, and is concrete, the diameter d=3.2mm when valve seat endoporus 3 of this valve seat, the length L of valve seat endoporus 3
2=9.6mm equals 3 times of its diameter d.
Concrete, noise reduction bidirectional throttling valve of the present utility model also can adopt the following parameters data to realize:
Diameter d=the 3.2mm of valve seat endoporus 3, the length L=3.2mm of valve seat endoporus can be with noise control below 55 decibels;
Diameter d=the 3.2mm of valve seat endoporus 3, the length L=9.6mm of valve seat endoporus can be with noise control below 50 decibels;
Diameter d=the 3.2mm of valve seat endoporus 3, the length L=4.8mm of valve seat endoporus can be with noise control below 55 decibels;
Certainly, the diameter d of valve seat endoporus 3 also can adopt other numerical value according to actual needs, and the length L of valve seat endoporus is done corresponding the adjustment along with the variation of the diameter d of valve seat endoporus 3, and its principle is identical, is not repeated.
For at two valve seats 2 of when assembling difference, the length that noise reduction bidirectional throttling valve of the present utility model also can one of them valve seat 2 is set to the length greater than another valve seat 2, adopts the choke valve of this structure, can be convenient to distinguish two valve seats 2, prevents from obscuring.Concrete, in manufacturing process, the length of the slideway 4 of two valve seats 2 is set to equate, valve seat endoporus 3 length of one of them valve seat 2 are greater than valve seat endoporus 3 length of another valve seat 2, make the structure of the spool 5 in two valve seats 2 can be identical, only the mode of the length by changing valve seat endoporus 3 can be distinguished two valve seats 2, reduces cost of manufacture.Further, the length difference between two valve seats 2 is more than or equal to 3.5mm, and difference obviously is difficult for obscuring.Adopt the noise reduction bidirectional throttling valve of this structure, the diameter d of the valve seat endoporus 3 of two valve seats 2 and the length L of valve seat endoporus are same as the previously described embodiments, are not repeated.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
