Abstract
The utility model discloses a kind of stop valve, comprise valve body, valve gap, valve rod and handle, described valve rod is provided with flap, the vertical shape of described flap end is provided with intercepter plate, the close medium that described intercepter plate is connected to flap end flows into passage end limit, and the shaft length size of described intercepter plate is less than the diameter dimension of the medium inflow channel cross-section that same intercepter plate axial direction extends; Described intercepter plate is inverted cone cylinder, and the dome face of described inverted cone cylinder is run through in the circular groove of flap end, and the cone vertex (vertices) of described inverted cone cylinder is free end.The stop valve that the utility model provides, closing valve process medium is reduced to the pressure of flap by setting up parts, reduce flap pressurized excessive impaired, make flap engage with valve seat smoothly to seal, while extending the flap life-span, lift-off seal performance, have structure simple, easy to make, use reliable, practical advantage.
Description
Technical field
The utility model relates to a kind of stop valve, belongs to valve field.
Background technique
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve; The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or the extra large conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod has lifting rotation rod-type, can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Therefore, such stop valve valve that dams is suitable as and cuts off or regulate and throttling use very much.Valve rod due to such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for regulating flow.
But, in actual motion using process, when medium is by when entering valve below flap, the resistance overcome required for steering force, the frictional force of valve rod and filler and the thrust produced by the pressure of medium, so the power that there is the force rate valve opening door of closing valve wants large difference, therefore require that the diameter of valve rod wants large, otherwise the fault of valve rod bending can occur; And fluid resistance is large in long-time running, sealing reliability reduces.
Model utility content
Main purpose of the present utility model is, overcome deficiency of the prior art, a kind of stop valve of new structure is provided, closing valve process medium is reduced to the pressure of flap by setting up parts, reduce flap pressurized excessive impaired, make flap engage with valve seat smoothly to seal, while extending the flap life-span, lift-off seal performance.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of stop valve, comprise valve body, valve gap, valve rod and handle, described valve rod is provided with flap, the vertical shape of described flap end is provided with intercepter plate, the close medium that described intercepter plate is connected to flap end flows into passage end limit, and the shaft length size of described intercepter plate is less than the diameter dimension of the medium inflow channel cross-section that same intercepter plate axial direction extends; Described intercepter plate is inverted cone cylinder, and the dome face of described inverted cone cylinder is run through in the circular groove of flap end, and the cone vertex (vertices) of described inverted cone cylinder is free end.
The utility model is set to further: the periphery of described inverted cone cylinder is provided with impeller.
The utility model is further set to: described inverted cone cylinder is the hollow rounding centrum of periphery Openworks shape.
The utility model is further set to: described impeller is uniformly distributed.
The utility model is further set to: described impeller is elasticity impeller.
The utility model is further set to: described inverted cone cylinder and impeller one-body molded.
Compared with prior art, the beneficial effect that the utility model has is:
By arranging these parts of intercepter plate at the vertical shape of flap end, make stop valve in closing valve process, intercepter plate plays the effect of being lived by dielectric impedance in advance, thus the medium entered below minimizing flap is to the pressure of flap, reduce flap pressurized excessive and damage may be caused, strengthening flap simultaneously and engage the smooth operation sealed with valve seat, extend the flap life-span, and lift-off seal performance, so use reliable, practical.
Foregoing is only the general introduction of technical solutions of the utility model, and in order to clearer understanding technological means of the present utility model, below in conjunction with accompanying drawing, the utility model will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of stop valve of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of stop valve, comprise valve body 1, valve gap 2, valve rod 3 and handle 4, described valve rod 1 is provided with flap 5, the vertical shape of described flap 5 end is provided with intercepter plate 6, the close medium that described intercepter plate 6 is connected to flap 5 end flows into passage end limit, and the shaft length size of described intercepter plate 6 is less than the diameter dimension in the medium inflow path 10 cross section that same intercepter plate 6 axial direction extends.
Wherein, described intercepter plate 6 is inverted cone cylinder, and the dome face of described inverted cone cylinder is run through in the circular groove of flap 5 end, and the cone vertex (vertices) of described inverted cone cylinder is free end.
Further, the periphery of described inverted cone cylinder is provided with impeller 61; Described impeller 61 is equally distributed elasticity impeller.
Further, described inverted cone cylinder is the hollow rounding centrum of periphery Openworks shape; Described inverted cone cylinder and impeller 61 one-body molded.
Innovative point of the present utility model is, by arranging these parts of intercepter plate at the vertical shape of flap end, make stop valve in closing valve process, intercepter plate plays the effect of being lived by dielectric impedance in advance, thus the medium entered below minimizing flap is to the pressure of flap, reduction flap pressurized is excessive and may cause damage, and strengthen flap engages the smooth operation sealed simultaneously with valve seat, extend the flap life-span, and lift-off seal performance; Have structure simple, easy to make, use reliable, practical advantage.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
