Routinely, valve plate is installed in the free end of compresser cylinder, fixes or be pressed against the end of the compression cylinder,
Or any similar additional components.Anyway, conventional valve plate is subject to the installing force that can change its physical integrity.
When the suction of valve plate and/or tap include conventional circumference, especially circular circumference, valve plate has and can connect
Deformed by degree.When suction and/or tap include conventional circumference, especially elliptical circumference, valve plate, which has, to make us
The deformation of the degree of puzzlement.
Fig. 1 shows the valve plate 1 of the completely rounded traditional mode of circumference.The valve plate 1 includes at least one 2 He of inlet hole
At least one tap 3.As previously mentioned, the valve plate 1 further comprises being subject to due to the installing force of head assembly and solid
The region FA of the high flexibility of the physical deformation of fixed output quota life.
Specifically, the high flexibility region FA referred to is deformed in piston direction, such as tends to deform to compression cylinder.This
Kind deformation directly affects the service quality of reciprocating compressor；After all, piston can hit inlet valve and valve plate, produce noise and/
Or the destruction of valve.
Obviously, if valve plate 1 does thicker, high flexibility region FA can less be influenced by physical deformation, but the valve
The thickness of plate 1 is bigger, discharges that the dead volume of the compressor of bore region is bigger, which is unfavorable for total effect of reciprocating compressor
Rate.
So as to can be observed, on the one hand, it is expected that reciprocating compressor valve plate has minimum possibility thickness, but the opposing party
Face, it is known that the thickness of reciprocating compressor valve plate is smaller, and the physical deformation in its high flexibility region is bigger.So as to based on this feelings
Condition, proposes the utility model.
Utility model content
Thus, the main target of the utility model is to disclose a kind of new structure part for introducing reciprocating compressor valve plate,
The structural member allows to reduce being automatically increased for physical deformation of the valve plate thickness without causing its high flexibility region.
Correspondingly, one of target of the utility model is that the design feature of valve plate does not damage total effect of reciprocating compressor
Rate.
One side according to the present utility model, there is provided a kind of structural member being introduced into reciprocating compressor valve plate, it is described
Valve plate includes at least one inlet hole and at least one tap, which includes being arranged in the interior zone of inlet hole
At least one structure protuberance；The inlet hole is divided into mutually independent at least two region by the structure protuberance；Institute
The gross thickness for stating valve plate is more than the gross thickness of the structure protuberance.
Preferably, the structural member further comprises that part and/or installation alignment portion are guided at least one installation.
Brief description of the drawings
The utility model will be described in detail on the basis of the attached drawing being listed below, wherein：
Fig. 1 shows reciprocating compressor valve plate according to prior art；
Fig. 2 shows reciprocating compressor valve plate according to the present utility model.
Embodiment
Preceding aim is fully achieved by a kind of structural member for introducing reciprocating compressor valve plate, and the structural member is in fig. 2
Schematically show.
According to described Fig. 2, it is noted that reciprocating compressor valve plate 1 has substantially rounded form and by metal alloy system
Into.
The valve plate 1 includes the inlet hole 2 of elliptic curve form and the tap 3 of circular form.
Generally speaking, valve plate 1 includes inlet hole 2 and tap 3, can pass through punching press, cutting, sintering or casting process system
Into widely known to those skilled in the art.
It is furthermore noted that the valve plate 1 further comprises structure protuberance 4, which is arranged in inlet hole 2
Interior zone by the inlet hole 2 to be divided into two mutually independent regions.
As shown in Figure 2, structure protuberance 4 includes a kind of column, is longitudinally arranged the interior zone in inlet hole 2,
Increase the mechanical strength of whole valve plate 1, and specifically, significantly increase visible Gao Rou in the valve plate for belonging to prior art situation
The mechanical strength of the zone similarity of property region FA.
The structure protuberance 4, preferably (but without limitation) be made of metal alloy, for example, valve plate 1 can obtained
Manufacturing process (punching press, cutting, sintering or casting) during realize or can after valve plate 1 is obtained pass through welding procedure reality
It is existing.
Especially in accordance with the utility model, it is noted that what the gross thickness that the structure protuberance 4 includes opposite valve plate 1 reduced
Thickness.This enables inlet valve (not shown) not contacted in sealing station with the structure protuberance 4, and only with inlet hole
2 general outline contact.
Functional effect of this feature for sealing (between unshowned inlet valve and inlet hole 2) is particularly important, finishes
Unexpectedly structure protuberance 4 is not only able to optimize the structural rigidity of valve plate 1 as a whole, and does not change the geometry of inlet hole 2
(its shape is usually reproduced profile by the unshowned inlet valve.
At least one its mechanical strength that can increase is included (especially about 2 He of inlet hole according to the utility model valve plate 1
The mechanical strength in the region of tap 3) structure protuberance 4, it is optimised to realize the gross thickness of valve plate, to increase reciprocating pressure
