Embodiment
In order to make the object of compressor valve plate of the present invention and compressor, technological scheme and advantage clearly understand, below in conjunction with concrete drawings and the specific embodiments, the present invention is further elaborated.
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 4, the invention provides a kind of compressor valve plate 100, comprise valve block head 110, valve block afterbody 120 and joint 130, described joint 130 is connected with described valve block head 110 and described valve block afterbody 120 respectively, wherein, the surface of the described valve block head 110 in the present embodiment is provided with flexible slot 111; Described valve block head 110 is divided into flexible part 112 and rigid portion 113 by described flexible slot 111, the side of described rigid portion 113 is connected with described joint 130, the opposite side of rigid portion 113 is connected with flexible part 112 by flexible slot 111, and namely described flexible part 112 is as shown in Figure 4 arranged on the outside of described rigid portion 113.
See Fig. 1 to Fig. 3, when compressor runs up, there is exhaust process (I to II process) and seal process (II to I process) in flange repeatedly.In exhaust process (I to II process), the gas in flange directly acts on compressor valve plate, and now the resistance that is subject to of gas is large, and the pressure loss is large; And when seal process (II to I process) closes to an end, housing intracavity gas pressure is greater than flange exhaust pressure, now because compressor valve plate fails to seal completely, therefore the endoceliac gas backflow of shell enters in cylinder chamber, thus compressor cold is reduced, power consumption increases, and compressor performance reduces.
In order to solve the problem, the present embodiment be provided with flexible slot 111 on the surface in one of them of valve block head 110, and the degree of depth of flexible slot 111 is less than the thickness of valve block head 110.After being provided with flexible slot 111, flexible part 112 can rotate around flexible slot 111.See Fig. 6, when flange is vented, the state of compressor valve plate is as shown in II in Fig. 6, due to the existence of flexible slot 111, the quality of whole compressor valve plate 100 reduces, and when being subject to the gas effect in flange when compressor valve plate 100, the flexible part 112 of valve block head 110 rotates along flexible slot 111, discharge flow area is increased, and gas is discharged smooth and easy, and the exhaust pressure loss of compressor is little.And at the end of exhaust, exhaust pressure due to flange is less than housing cavity pressure, now the state of compressor valve plate 100 is as shown in III in Fig. 6, now compressor valve plate 100 is under the effect of housing cavity pressure, the flexible part 112 of valve block head 110 rotates along flexible slot 111, flexible part 112 contacts with valve seat, seals in advance, thus avoids the endoceliac gas of shell to flow in cylinder.
Compressor valve plate in Fig. 3 at the end of exhaust because the reason of gas pressure is difficult in time well seal vents, and see Fig. 7 to Fig. 8, due to the existence of flexible slot 111, flexible part 112 rotates and contacts with the convex closure 210 of the flange sealed thus seal in advance in advance.Compressor valve plate of the present invention like this can be good at the gas alleviated in exhaust process and discharges resistance, at the end of can avoiding exhaust, in housing, gas backflow enters in cylinder chamber simultaneously, compressor power consumption can be reduced simultaneously, increase compressor cold, improve compressor performance.
Preferably, as a kind of embodiment, see Fig. 4, the two ends of described flexible slot 111 lay respectively at the joint at the edge of described valve block head 110 and the edge of described joint 130.That is on the valve block head 110 in the present embodiment, whole circle has flexible slot 111, and now two end points of flexible slot 111 lay respectively at the transition position of valve block head 110 and joint 130.The relative area arranging flexible part is like this comparatively large, and its rotation amplitude is larger.
Preferably, as another kind of embodiment, see Fig. 5, the two ends of described flexible slot 111 lay respectively at the edge of described valve block head 110 and the two ends of described flexible slot 111 all away from described joint 130.That is on the valve block head 110 in the present embodiment, local has flexible slot 111, and it can realize the rotation of valve block head 110 equally, and just rotation amplitude is less, and rigid portion 113 only part by flexible part 112 around.
Wherein, described flexible part 112 is 1:1 ~ 5 with the area ratio of described rigid portion 113.In the present embodiment, flexible slot 111 is arranged on the marginal position of valve block head 110.Such setting can be good at realizing flexible part and freely rotates around flexible slot.
Further, longitudinal section (thickness direction namely along valve block is cut open, the flexible slot 111 as in Fig. 8) shape of the flexible slot 111 in the present invention is rectangle, circle or zigzag fashion.Wherein circular and zigzag fashion processing difficulties, rectangle processing is relatively easy, and place's thickness of only need slotting is identical.
Preferably, see Fig. 4 and Fig. 5, the cross-section curve of the flexible slot 111 in the present invention comprises interconnective first paragraph 101, second segment 102 and the 3rd section 103; Wherein said first paragraph 101 is symmetricly set on the both sides of described second segment 102 with described 3rd section 103, and the shape of described second segment 102 and the edge shape of described valve block head 110 are all arc.Such setting can make flexible part 112 freely rotate.
More excellent, see Fig. 4 and Fig. 5, described second segment 102 is circular arc, wherein the center of circle of the second segment 102 of this arc-shaped overlaps with the center of circle of the boundary curve of described valve block head 110, forms isocentric circular arc, arranges convenient processing like this, and flexible part easily restores to the original state, long service life.
Preferably, the width of the described flexible slot in the present embodiment is 0.3mm ~ 0.6mm, and the degree of depth of described flexible slot accounts for 20% to 60% of described valve block head 110 thickness, and wherein the degree of depth of flexible slot 111 is 0.1mm ~ 0.4mm.
It should be noted that the compressor valve plate 100 in the present invention is formed in one, only need the relevant position processing flexibility groove at valve block head 110, processing technology is simple.
Accordingly, the present invention also provides a kind of compressor, it comprises the compressor valve plate 100 of above-mentioned any embodiment, and the valve block afterbody 120 of described compressor valve plate 100 is provided with mounting hole 121, and described compressor valve plate 100 is arranged on the flange of described compressor by mounting hole 121.See Fig. 8, wherein the convex closure 210 of flange should be corresponding with flexible slot 111, and the one side being provided with flexible slot 111 should towards housing chamber.Flexible part 112 can be made like this to contact with convex closure 210 better thus realize sealing effect in advance.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claim.
