Abstract
The utility model relates to a throttle valve for cast stone and slagging belongs to the valve class, which adopts the throttling valve composed of a valve body, a valve cover, a screw rod, a hand wheel fixed on the top end of the screw rod and a valve plate hinged on the lower end of the screw rod as the base. The inner wall of the valve body is cast with a cast stone layer. The gate plate adopts a gate plate frame whose one side or two sides are cast with cast stone layers. The position of the bottom surface of the inner wall of the valve body corresponding to the gate plate frame is provided with a metal support block. The throttle valve is particularly suitable for the water slag conveyance of water slagging and the coal conveyance of water power of the power plant.
Description
The utility model belongs to valve type.
In the pipeline of carrying slurry, the throttle valve of the outlet end of slag stock pump need often carry out throttle operation.The present throttle valve that uses, by valve body, valve gap, leading screw, be fixed on the leading screw top handwheel, be hinged on that the flashboard of leading screw lower end forms.The valve interior wall of this throttle valve and the wear resistance of flashboard are relatively poor, are are often worn and torn by slurry, cause the working life of valve very short.
The purpose of this utility model is: provide a kind of wear resistance good, the cast stone deslagging throttle valve of long service life.
Technical measures of the present utility model are: based on the existing throttle valve of being made up of the seal arrangement of valve body, valve gap, leading screw, the handwheel that is fixed on the leading screw top, the flashboard that is hinged on the leading screw lower end, leading screw and valve gap endoporus, be cast with one deck cast stone layer on the inwall of valve body; Flashboard is a flashboard skeleton, is cast with the cast stone layer in the skeleton one or both sides.
Cast stone deslagging throttle valve of the present utility model owing to be cast with the cast stone layer at valve interior wall and flashboard skeleton side, has that wear-resisting property is good, the good effect of long service life.
Accompanying drawing is a structural representation of the present utility model.
1 is valve body among the figure, and valve body is imported and exported two ends all flange plate, and the upper end-hole of valve body also has flange plate, is connected with valve gap 6 by sealing and bolt, in the valve gap 6 screw is arranged, and leading screw 11 is housed in the screw, leading screw 11 upper ends are fixed with handwheel 9 by locking nut 10; Be hinged with flashboard skeleton 4 in the leading screw lower end.The utility model improves working life in order to improve the wear-resisting property of throttle valve, is cast with one deck cast stone layer 2 on the inwall of valve body 1, changes original flashboard into the flashboard skeleton, and is cast with cast stone layer 5 in the skeleton one or both sides.Destroy in order to protect cast stone layer 2 and 5 not to be touched extruding, on the inwall bottom surface of valve body 1 and flashboard skeleton 4 corresponding positions, a metal support piece 3 is arranged.12 is lubricating cups among the figure, and leading screw 11 and screw are lubricated.Nut 8 among the figure is the seal arrangement of leading screw and valve gap endoporus with Gland 7 compositions.This cast stone deslagging throttle valve mainly is to be used for Water of Power Plant ash disposal, slag conveying, the defeated coal of waterpower.
Claims (2)
1, a kind of cast stone deslagging throttle valve is made up of the seal arrangement of valve body, valve gap, leading screw, the handwheel that is fixed on the leading screw top, the flashboard that is hinged on the leading screw lower end, leading screw and valve gap endoporus, it is characterized in that:
A, on the inwall of valve body, be cast with one deck cast stone layer:
