Description
Technical field：
Vavuum pump or air compressor machine technical field are the utility model is related to, refers in particular to a kind of pump valve board structure.
Background technology：
Pump is different according to purposes, and species is more, and the shape of product, size equal-specification are different.Vavuum pump entirety
The volume of this body support frame of volume, structure etc. with vavuum pump, structure etc. are closely related, and at present, the volume of vavuum pump valve plate is general
It is larger, and attachment structure design thereon is relatively simple rough, is unfavorable for the assembling of the accessories such as leaf valve, sealing ring, and produce
Product entirety space-consuming is larger, is unfavorable for the miniaturization of equipment, and scope of application limitation is larger.
Utility model content：
The purpose of this utility model is to overcome the weak point of existing product, there is provided a kind of pump valve board structure.
The technical solution adopted in the utility model is：A kind of pump valve board structure, including a valve plate body, the valve plate body
Extend rectangular main panel with the rounded, both sides in a middle part, upper surface middle part in main panel, be molded along its length
There is horizontal " mesh " font seal groove, the interior zone of horizontal " mesh " font seal groove is divided into left boss, middle boss, right convex
Three regions of platform, wherein, offer the air vent through main panel respectively in left boss, right boss, opened up in middle boss
There is leaf valve mounting hole；On the home panel, it is respectively equipped with a fixing hole at circular four angles with rectangle joining place；In interarea
The lower surface of plate, the both sides of border circular areas form the supporting plate bent downwards respectively, and the outside of two supporting plates is also molded respectively
There is tubular connecting portion, the left boss, the outer end of right boss are respectively equipped with the shrinkage pool communicated with the tubular connecting portion of respective side；
The lower surface of main panel, the edge of border circular areas form a circular seal groove.
The utility model valve plate uses integrated formed structure, and simple production process, production efficiency are high, compact-sized, are easy to
The assembling of the accessories such as leaf valve, sealing ring, and receiving space is formed in arcuation, with pump housing stable connection and occupying little space.
Brief description of the drawings：
Fig. 1 is top view of the present utility model；
Fig. 2 is upward view of the present utility model；
Fig. 3 is front view of the present utility model；
Fig. 4 is side view of the present utility model.
Embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As Figure 1-Figure 4, described in the utility model is a kind of pump valve board structure, including a valve plate body, the valve
There are plate body the rounded, both sides in a middle part to extend rectangular main panel 1, upper surface middle part in main panel 1, along length
Direction forms horizontal " mesh " font seal groove 11, and horizontal " mesh " font seal groove 11 is used to install the sealing of " mesh " font
Circle；The interior zone of horizontal " mesh " font seal groove 11 is divided into 14 3 left boss 12, middle boss 13, right boss regions, its
In, offer the air vent 101 through main panel 1 respectively in left boss 12, right boss 14, two air vents 101 1
As air admission hole, one be venthole, distinguished according to the purposes of pump；Leaf valve mounting hole 131 is offered in middle boss 13,
For installing two leaf valves, and two leaf valves in a first from left it is right, install one on the other, i.e. during the inner of leaf valve is fixed on
The leaf valve mounting hole 131 of boss 13, outer end then cover air vent 101, the corresponding leaf valve of an air vent 101；
A fixing hole 102 is respectively equipped with main panel 1, at circular four angles with rectangle joining place, totally four, the fixing hole 102
Effect be with covering bonnet above it and being bolted to connection with the pump assembly of lower section by valve plate；Actually make
In, valve plate upper surface installation bonnet, valve plate lower surface is docked with the pump housing；In the lower surface of main panel 1, the both sides of border circular areas
The supporting plate 15 bent downwards is formed respectively, receiving space is formed between supporting plate 15, is installed for accommodating on pump assembly
The cylinder of piston；The outside of two supporting plates 15 also forms tubular connecting portion 16 respectively, the left boss 12, right boss 14 it is outer
End is respectively equipped with the shrinkage pool 103 communicated with the tubular connecting portion 16 of respective side；The both ends of tubular connecting portion 16 are according to the effect of pump
External equipment or selection closing are connected with type selecting；One is formed in the edge of the lower surface of main panel 1, border circular areas
Circular seal groove 17, the circular seal groove 17 are to be used to set O-ring seals, to realize that sealing is docked with cylinder upper surface.
The utility model valve plate uses integrated formed structure, and simple production process, production efficiency are high, compact-sized, are easy to
The assembling of the accessories such as leaf valve, sealing ring, and receiving space is formed in arcuation, with pump housing stable connection and occupying little space.
