Abstract
A valve plate structure of a valve comprises a cap-shaped circular valve plate body with the middle protruding outwards towards one side. A shallow protruding strip is arranged in the middle of the outwards-protruding face of the valve plate body in the diameter direction, and two opposite and radially-arranged rotary shaft holes are separately formed in the edges, located at the two ends of the protruding strip, of the valve plate body; a groove which corresponds to an outer circle and is provided with an arc-shaped bottom face is formed in the inner surface of the valve plate body, and the thicknesses of the bottom face of the groove and the outwards-protruding face are gradually increased from the outside to the inside; a flange sealing edge is arranged on the periphery of the valve plate body, and a transverse through hole and two transverse through holes located in the same center line are formed in the outer surfaces of the two ends of the shallow protruding strip and correspond to the rotary shaft holes; and in addition, outwards-protruding and approximately-semicircular protruding surfaces are arranged on the portions, located on the two sides of the shallow protruding strip, of the outwards-protruding face of the valve plate body. The valve plate structure of the valve has the characteristics of simple structure, flexible using and operation, light and handy whole, high pressure bearing capacity, long service life and the like.
Description
Technical field
The present invention relates to a kind of valve board structure of valve, belong to valve technology field.
Background technology
Valve be mainly used for pipeline connect and control piper logical only, seen valve kind is relatively in the market
Many, can need to select the valve of different cultivars, such as gate valve, electromagnetic valve, flap valve, butterfly valve and three-way valve etc. according to different
Deng including butterfly valve in interior, valve that is being mainly used in big flow pipeline, being the deflection size control passing through valve plate in valve body
The flow of fluid processed, this valve board structure descends requirement can bear the fluid uniaxial pressure of big flow, therefore valve in off position
The structure composition of plate is related to using effect and the service life of valve, using thicker valve plate although bearing capacity strengthens, but
Overall heavy, operate underaction；And cost increases, and installs and uses inconvenience；Although, operation spirit light and handy using relatively thin valve plate
It is convenient to live, but bearing capacity reduces, and affects service life and using effect.
Content of the invention
It is an object of the invention to overcoming the shortcomings of that prior art exists, and provide a kind of structure simple, using operation spirit
Live, overall light and handy, bearing capacity is big, the valve board structure of the valve of long service life.
The purpose of the present invention to complete by following technical solution, a kind of valve board structure of valve, and it is included in one
Between be lid circular valve plate body to side evagination, the arcuate surface middle setting of described valve plate body has diametrically one
Shallow raised line, and opposite, radial arrangement a shaft hole is offered on the valve plate body edge at this raised line two ends, in institute respectively
Be provided with the inner surface stating valve plate body and cylindrical corresponding, the curved face in bottom surface recessed groove, the bottom surface of described recessed groove with
The thickness of arcuate surface is from outside to inside in gradually thickening state.
As preferred：The circumferential edge of described valve plate body is provided with flange seal side；The outer surface at described shallow raised line both ends
On corresponding to shaft hole, be respectively arranged with a cross through hole and two two cross through hole being in same centrage；Separately exist
On the arcuate surface of valve plate body, the both sides that are located at shallow raised line be respectively arranged with the approximate half-circular convex surfaces of evagination.
The present invention has that structure is simple, and using flexible operation, overall light and handy, bearing capacity is big, the features such as long service life.
Brief description
Fig. 1 is the side sectional view of valve plate body of the present invention.
Fig. 2 is the structure schematic diagram of valve plate body of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail：Fig. 1, shown in 2, a kind of valve plate of valve of the present invention
Structure, it includes being the lid circular valve plate body 1 to side evagination in the middle of one, the arcuate surface middle setting of described valve plate body 1 has
A shallow raised line 2 diametrically, and offer one on valve plate body 1 edge at this shallow raised line 2 two ends respectively in opposite directions
, the shaft hole 3 of radial arrangement, the inner surface of described valve plate body 1 is provided with and cylindrical corresponding, the curved face in bottom surface 4
Recessed groove 5, to reduce the weight of valve plate body, reduces cost；The bottom surface of described recessed groove 5 is from outer with the thickness of arcuate surface 6
Inwardly in gradually thickening state, to strengthen the comprcssive strength of valve plate body 1.
Shown in figure, the circumferential edge of valve plate body 1 of the present invention is provided with flange seal side 7；Described shallow raised line 2 both ends
Outer surface on, be respectively arranged with a cross through hole 8 corresponding to shaft hole 3 and two be in two of same centrage laterally
Through hole 8；Another on the arcuate surface 6 of valve plate body 1, be located at shallow raised line 2 both sides be respectively arranged with evagination approximate half-circular raised
Surface 9, its effect is also for the axial compression strength strengthening valve plate body.
Claims (2)
1. a kind of valve board structure of valve, it includes be lid circular valve plate body to side evagination in the middle of one it is characterised in that
The arcuate surface middle setting of described valve plate body has a shallow raised line diametrically, and the valve plate body side at this raised line two ends
One opposite, radial arrangement shaft hole is offered respectively on edge, the inner surface of described valve plate body is provided with cylindrical
The recessed groove in the curved face in corresponding, bottom surface, the bottom surface of described recessed groove and the thickness of arcuate surface are to be in gradually to become from outside to inside
Shape thickness state.
2. the valve board structure of valve according to claim 1 is it is characterised in that the circumferential edge of described valve plate body is provided with method
Blue sealing strip；Shaft hole is corresponded on the outer surface at described shallow raised line both ends, is respectively arranged with a cross through hole and two
