Fig. 1 is the sectional view of a kind of scroll compressor 100 of diagram.
As shown in Figure 1, scroll compressor 100 comprises columnar seal casinghousing 120, compressing mechanism (vortex) 140, main shaft bearing sleeve 160, driving mechanism 180, exhaust joint 200 and air input joint 220.Seal casinghousing 120 holds compressing mechanism 140 and driving mechanism 180.Air input joint 220 is arranged on the housing 120, is used to suck the gaseous refrigerant of low pressure.One end of housing 120 is fixedly connected with end cap 240.Exhaust joint 200 is arranged on the end cap 240, is used to discharge the refrigeration agent after the compression.Between housing 120 and end cap 240, also be provided with the acoustical panel 300 of axial direction horizontal expansion (in Fig. 1, extending), thereby the inner space of compressor is separated into high pressure side and low voltage side for direction along approximate horizontal with respect to housing 120.Space between end cap 240 and the acoustical panel 300 constitutes the space, high pressure side, and the space between acoustical panel 300 and the housing 120 constitutes the low voltage side space.The pedestal 280 that is positioned at housing 120 bottoms is used for compressor 100 is installed to system chassis.
The compressor structure that has been the example brief description with the scroll compressor above.Further describe below with reference to figure 2.Fig. 2 is the schematic representation of the position of illustrated valve assembly 1 in scroll compressor.This valve member 1 can be the high efficiency volumetric valve.As shown in Figure 2, according to the structure of scroll compressor, can the space that hold the refrigeration agent after the compression be designated as drain chamber 5, and the zone that will produce the refrigeration agent after the compression is designated as discharge pressure zone 2.Between discharge pressure zone 2 and drain chamber 5, there is discharge passage 3.Discharge passage 3 connects discharge pressure zone 2 and drain chamber 5, so that the refrigeration agent after the compression can enter into drain chamber 5 from discharge pressure zone 2.The related valve member 1 of one or several embodiment of the utility model just is arranged in the discharge passage 3.Usually by means of nut 4 valve member 1 is installed in the discharge passage 3.
For the purpose of this specification more clearly is described, describe with reference to figure 3 below.Fig. 3 is the exploded view of the constituent element of a kind of valve member 1 of diagram.
As shown in Figure 3, valve member 1 can comprise valve seat 9, valve block 8, valve plate 7 and screw pin 6.Valve plate 7 is provided with the hole 10 (being referred to as exhaust port hereinafter) that is used for exhaust, and this exhaust port 10 is used for making the refrigeration agent after the compression to enter into drain chamber 5 from discharge pressure zone 3.In addition, also be provided with positioning hole 11 on the valve plate 7, and the corresponding position on valve block 8 and the valve seat 9 also is provided with positioning hole corresponding (indicating).In example shown in Figure 3, the number of the positioning hole on valve plate 7, valve block 8 and the valve seat 9 is respectively 2, with corresponding with 2 screw pins 6.Screw pin 6 can be inserted in the positioning hole 11, with normal valve door assembly 1.
It should be noted that; According to one or several embodiment's of the utility model valve member can adopt except screw pin 6 and with it the those skilled in the art the corresponding positioning hole 11 other known orientation type locate; And the number of screw pin 6 and positioning hole 11 also is not limited to 2, and the utility model does not have particular restriction to this.
Valve block 8 has movable part 12, and this movable part 12 is used for the exhaust port 10 on the opening and closing valve plate 7.Valve seat 9 can limit the moving of movable part 12 of valve block 8.When air communication is crossed the exhaust port 10 on the valve plate 7 and when the movable part 12 of valve block 8 was moved, movable part 12 can be crooked towards the direction of valve seat 9, finally can contact with the limitation part (not shown in Fig. 3) of valve seat 9.So, valve seat 9 has just limited moving of movable part 12, the fatigue fracture because its distortion is excessive to avoid valve block 8.
As as described in the background technique part of the utility model, under the same conditions, the pressure drop that valve member generates is big more, and then pressure is big more in the vortex port.Then, compressor will be worked harder, and motor can generate more heat.Therefore, good valve member should have less pressure drop, and can cause less influence to compressor efficiency.
Usually, the pressure drop that produces on the valve member is relevant with exhaust port, the thickness of valve block and the geometrical shape of valve seat etc. in the valve plate.Generally speaking, the fluid passage in the valve member should make fluid flow glossily.Passage is wide more, turns to fewly more, and bottleneck is few more, and then flow resistance is more little, and pressure drop is more little.
In order to further specify the circulation area in the valve member, below describe with reference to figure 4-7.Fig. 4 is the schematic representation of the circulation area on the diagram valve plate 7; Fig. 5 is the schematic representation of diagram circulation area 13 between valve plate 7 and the valve block 8 when valve block 8 unlatchings; Fig. 6 is shown in the schematic representation that the circulation area 14 on the valve seat 9 before the nut is installed, and Fig. 7 is shown in the schematic representation that the circulation area 15 on the valve seat 9 after the nut 4 is installed.
As shown in Figure 4, valve plate 7 is provided with an exhaust port 10 and two positioning holes 11.When valve member was worked, fluid flowed into from exhaust port 10.Therefore, the area of exhaust port 10 is the circulation area of fluid on valve plate 7.
Next with reference to figure 5, when valve block 8 is opened, that is when fluid moved the movable part 12 of valve block 8 through the exhaust port on the valve plate 7 10, movable part 12 can be crooked towards the direction of valve seat 9.At this moment, between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8, formed circulation area 13.This circulation area 13 can be regarded the lateral area of cylinder as, and the exhaust port 10 of the bottom surface of said cylinder and valve plate 7 is overlapping, and the end face of said cylinder is formed by movable part 12 these cylinders of cutting of valve block 8.Therefore, the size of circulation area 13 is by the area of exhaust port 10 and the degree of crook decision of movable part 12.
Next with reference to figure 6, when fluid enters into valve seat 9 through the circulation area 13 between the exhaust port on the valve plate 7 10 and valve plate 7 and the valve plate 8, in valve seat 9, form circulation area 14.Obviously, the size of circulation area 14 is decided by horizontal cross-sectional area and the horizontal cross-sectional area of the support part of the outer shroud that is positioned at valve seat 9 of the limitation part that moves that is used to limit movable part 12 of valve seat 9.
Next with reference to figure 7, after nut 4 is installed, in valve seat 9, further form circulation area 15.At this moment, the size of circulation area 15 is then decided by the horizontal cross-sectional area of the entity part of the horizontal cross-sectional area of the horizontal cross-sectional area of limitation part, support part and nut 4.Here, the entity part of nut 4 refers to the part that is made up of real material that does not comprise intermediate throughholes of nut 4.Generally speaking, the horizontal cross-sectional area of the entity part of nut 4 can be greater than the horizontal cross-sectional area of the support part of valve seat 9.When the lower end of nut 4 contacted with the upper surface of valve seat 9, the rear surface of the entity part of nut 4 might cover the upper surface of the support part of valve seat 9 fully.In this case, the big young pathbreaker of circulation area 15 is decided by the horizontal cross-sectional area of the entity part of the horizontal cross-sectional area of limitation part and nut 4.
A kind of simple but effective method that reduces the pressure drop that produces on the valve member is exactly the circulation area that increases fluid.
In order to increase the circulation area of fluid, the most directly mode is exactly the area that increases the exhaust port 10 on the valve plate 7, and is as shown in Figure 8.Fig. 8 is that diagram enlarges the schematic representation of the area of the exhaust port 10 on the valve plate 7 with the increase circulation area.Because the area of exhaust port is the circulation area of fluid on valve plate 7, so the exhaust port 10 ' that area is enlarged has increased the circulation area of fluid on valve plate 7.
Simultaneously, with reference to figure 5, because the size of circulation area 13 is by the area of the exhaust port on the valve plate 7 and the degree of crook decision of the movable part 12 on the valve block 8, so the exhaust port 10 ' that area is enlarged has equally also increased circulation area 13.
But; Because the enlarged areas of the exhaust port on the valve plate 7, thus the area of the movable part 12 on the valve block 8 must correspondingly enlarge, to guarantee when valve member is closed; The movable part 12 of valve block 8 can cover the exhaust port on the valve plate 7, and is as shown in Figure 9.The schematic representation of Fig. 9 exhaust port 10 ' that to be the diagram area that enlarges the movable part 12 on the valve block 8 enlarged with the area that hides on the valve plate shown in Figure 87.
So; Because the enlarged areas of the movable part 12 on the valve block 8; So the horizontal cross-sectional area of the limitation part 16 on the valve seat 9 must correspondingly enlarge; Guaranteeing when valve member is opened, the limitation part 16 of valve seat 9 can limit the moving of movable part 12 of valve block 8 with higher reliability, and is shown in figure 10.The schematic representation that moves of Figure 10 movable part 12 ' that to be the diagram horizontal cross-sectional area that enlarges the limitation part 16 on the valve seat 9 enlarged with the area that limits on the valve block shown in Figure 98.
At this moment because the horizontal cross-sectional area of the limitation part 16 on the valve seat 9 enlarges, so the circulation area 14 that determines by the horizontal cross-sectional area of the horizontal cross-sectional area of limitation part 16 and support part correspondingly diminish, shown in figure 11.Figure 11 is shown in the schematic representation that the variation of the circulation area 14 on the valve seat 9 when the horizontal cross-sectional area expansion of the limitation part on the valve seat 9 16 before the nut is installed.Likewise; After nut 4 is installed; Also correspondingly diminish by the horizontal cross-sectional area decision of the entity part of the horizontal cross-sectional area of the horizontal cross-sectional area of limitation part 16, support part and nut 4 or by the circulation area 15 of the horizontal cross-sectional area decision of the entity part of the horizontal cross-sectional area of limitation part 16 and nut 4, shown in figure 12.Figure 12 is shown in the schematic representation that the variation of the circulation area 15 on the valve seat 9 when the horizontal cross-sectional area expansion of the limitation part on the valve seat 9 16 after the nut 4 is installed.
Can know from above description; In order to increase the circulation area of fluid; If increase the area of the exhaust port 10 on the valve plate 7 simply; Then the circulation area of fluid on valve plate 7 increases, and the circulation area 13 that between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8, forms also can increase, but install before the nut 4 with afterwards valve seat 9 on circulation area 14 and 15 can correspondingly reduce.Therefore, reducing the pressure drop that produces on the valve member just can regard area at the exhaust port on the valve plate 7 10, the circulation area 13 that between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8, forms as and nut 4 is installed and average out before and between the circulation area 14 and 15 on the valve seat 9 afterwards.
A kind of considerable method is; Not to the area of the exhaust port on the valve plate 7 10 and under the situation that the circulation area 13 that forms between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8 impacts, increase the circulation area 14 on the valve seat of installing before the nut 49.As stated, circulation area 14 is by the horizontal cross-sectional area of limitation part 16 and the horizontal cross-sectional area decision of support part.The horizontal cross-sectional area sum of the horizontal cross-sectional area of limitation part 16 and support part is big more, and then circulation area 14 is more little, and is shown in figure 11.If can reduce the horizontal cross-sectional area of support part, then circulation area 14 will correspondingly enlarge.Based on such thinking, proposed a kind of improved valve seat, shown in figure 13.Figure 13 is that diagram is improved to increase the schematic representation of circulation area 14 valve seat 9.
In the valve seat 9 ' after improvement, the part of support part 17 that is positioned at the outer shroud of valve seat 9 ' is excised.So; The horizontal cross-sectional area of support part 17 just is reduced; And circulation area 14 correspondingly enlarges, and also can not impact the area of the exhaust port on the valve plate 7 10 and the circulation area 13 that between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8, forms simultaneously.Therefore, the valve seat 9 ' after the improvement can increase the circulation area of fluid, thereby can reduce the pressure drop that produces on the valve member.
Yet in the valve seat 9 ' after improvement, the distribution angle that the part that the quilt of support part 17 excises occupies on the outer shroud of valve seat 9 ' can not surpass 180 degree.This be because; After the assembling of valve member is accomplished; If have only fewer than half the part on the whole outer shroud circumference of support part 17 of valve seat 9 ' to be pressed on the valve plate 7; Then support part 17 possibly be not enough to valve plate 7 efficient pressure is provided, and causes the side that the portion that is not supported 17 of valve plate 7 pushes down at work might perk, causes the vortex of compressor and the leakage between the valve plate 7.Therefore, to increase the circulation area of fluid be limited (part of being excised can not surpass half the on the outer shroud circumference) to the part through excision support part 17 shown in figure 13.
Another kind of considerable method is; Not to the area of the exhaust port on the valve plate 7 10 and under the situation that the circulation area 13 that forms between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8 impacts, increase the circulation area 15 on the valve seat of installing after the nut 49.As stated; Circulation area 15 is by the horizontal cross-sectional area decision of the entity part of the horizontal cross-sectional area of the horizontal cross-sectional area of limitation part 16, support part and nut 4, and perhaps the horizontal cross-sectional area by the entity part of the horizontal cross-sectional area of limitation part 16 and nut 4 determines.The horizontal cross-sectional area of the entity part of the horizontal cross-sectional area of limitation part 16, the horizontal cross-sectional area of support part and nut 4 is big more; Perhaps the horizontal cross-sectional area of the entity part of the horizontal cross-sectional area of limitation part 16 and nut 4 is big more; Then circulation area 15 is more little, and is shown in figure 12.If can reduce the horizontal cross-sectional area of the entity part of nut 4, then circulation area 15 will correspondingly enlarge.Based on such thinking, proposed a kind of improved nut, shown in figure 14.Figure 14 is that diagram is improved to increase the schematic representation of circulation area the hole in the nut 4.
In the nut 4 after improvement, the valve seat 9 contacted ends in nut 4 and valve member are provided with cone shape hole.The diameter d of the horizontal section bottom of cone shape hole is greater than the diameter of the horizontal section of other position in the hole in the nut 4.Because the setting of cone shape hole; Be reduced with the horizontal cross-sectional area of the entity part of the contacted nut 4 of valve member; Circulation area 15 then correspondingly enlarges, and also can not impact the area of the exhaust port on the valve plate 7 10 and the circulation area 13 that between the movable part 12 of the exhaust port 10 of valve plate 7 and valve block 8, forms simultaneously.Therefore, the nut 4 after the improvement can increase the circulation area of fluid, thereby can reduce the pressure drop that produces on the valve member.
Yet in the nut 4 after improvement, the diameter d of the horizontal section bottom of cone shape hole receives many factor restrictions, for example can receive minor diameter and tolerance, the tolerance of diameter d and the restriction of the build-up tolerance of valve member on axial direction of screw thread.Therefore, to increase the circulation area of fluid also be limited to the diameter d of the horizontal section bottom through increasing cone shape hole.
In order to increase the circulation area of fluid to a greater extent, the valve member according to one or several embodiment of the utility model is provided.Valve member according to one or several embodiment of the utility model has carried out further improvement to valve seat, simultaneously other parts in the valve member is not had particular restriction.
Figure 15 is the schematic representation of diagram according to the valve seat 90 in one or several embodiment's of the utility model the valve member.Shown in figure 15; Valve seat 90 according in one or several embodiment's of the utility model the valve member roughly is similar to valve seat 9 ' shown in Figure 13; Difference is that valve seat 90 does not comprise the support part 17 as in the valve seat 9 ', but has comprised first support part 18 and second support part 19.
