Abstract
The utility model provides a kind of novel water power special sewage globe valve flashboard, it is characterized in that: the frustum type that the outer surface of the seal of flashboard reduces gradually in diameter from bottom to top, and sealing surface is covered on the outer surface of sealing body.Conical guiding slip positioning head is extended at the top of the seal of flashboard, and the top of guiding slip positioning head is the sphere seamlessly transitted.The utility model is by changing plane sealing face original for the sealing surface of flashboard as taper sealing face into; on flashboard, increase by a joint guiding slip positioning head again; flow and the flow velocity of control of sewage disposal discharging valve current when opening and closing is come by flashboard; reduction current and sediments, to the erosive force in ram seal face, reach the effect in protection ram seal face.
Description
Technical field
The utility model belongs to a kind of valve, particularly relates to a kind of blowdown valve valve board structure.
Background technique
A blowdown discharging valve is all equipped with, for cost-saving and easy-to-operat are all generally adopt conventional stop valve to use as blowdown discharging valve below the main valve of existing water power plant.
As shown in Figure 1, the end face of existing flashboard 1 ' is plane 10 ', and the sealing surface 11 ' of its plane form coordinates contact with the sealing surface 21 ' of valve seat 2 ', realizes sealing.
Because the water source in water power plant is generally all natural water source, understand some foreign material such as silt and stone and be deposited on bottom main valve in hydroelectric station operation, this Parts of deposits just only has to be got rid of by blowdown discharging valve.In this process, in pipeline, sediments is just very large to the erosion of valve sealing face, also just causes valve can greatly shorten working life, strengthens the operating cost in power station and the loss of water resources.
Model utility content
The utility model provides the design of the special sewage globe valve flashboard of a kind of novel water power; its objective is the shortcoming solving prior art and exist; the erosion of sediments to sealing surface can be effectively reduced, to reach the object that protection valve sealing face extends valve working life simultaneously.
The utility model solves the technological scheme that its technical problem adopts:
The special sewage globe valve flashboard of a kind of novel water power, is characterized in that: the frustum type that the outer surface of the seal of flashboard reduces gradually in diameter from bottom to top, and sealing surface is covered on the outer surface of sealing body.
Conical guiding slip positioning head is extended at the top of the seal of flashboard, and the top of guiding slip positioning head is the sphere seamlessly transitted.
Usefulness of the present utility model is:
The utility model is by changing plane sealing face original for the sealing surface of flashboard as taper sealing face into; on flashboard, increase by a joint guiding slip positioning head again; flow and the flow velocity of control of sewage disposal discharging valve current when opening and closing is come by flashboard; reduction current and sediments, to the erosive force in ram seal face, reach the effect in protection ram seal face.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is prior art structural drawing;
Fig. 2 is the utility model structural drawing.
Embodiment
As shown in Figure 2, the structure of flashboard of the present utility model comprises two-part, seal 1 and guiding slip positioning head 2, the frustum type that the outer surface of the seal 1 of flashboard reduces gradually in diameter from bottom to top, sealing surface 3 is covered on the outer surface of sealing body 1, and also namely sealing surface 3 has tapering.
Conical guiding slip positioning head 2 is positioned at the top of seal 1, and guiding slip positioning head 2 is one with seal 1, the sphere of top 21 for seamlessly transitting of guiding slip positioning head 2.
This flashboard plug screw is fixed on valve rod 5, the sealing surface 3 of flashboard is towards the sealing surface 4 of valve seat 6, the top 21 of guiding slip positioning head 2 is towards valve seat 6, when closing flashboard, guiding slip positioning head 2 stretches into valve seat 6, the surface of the sphere top 21 seamlessly transitted of guiding slip positioning head 2 and taper is thereafter played and is led and positioning action, and runner reduces gradually (during unlatching flashboard, runner becomes large gradually), current and flow velocity (direction of arrow is water (flow) direction) can be controlled and stop impurity in current, in order to avoid cause sealing face damage when closing flashboard simultaneously; After closing completely, the sealing surface 3 of flashboard and the sealing surface 4 of valve seat 6 coordinate contact to realize sealing, because the sealing surface 3 of flashboard is taper, reduce current and sediments to the erosive force of the sealing surface 3 of flashboard.
