Abstract
The utility model discloses a pneumatic plate turning type powder body feeding valve. The pneumatic plate turning type powder body feeding valve comprises a valve body, an air cylinder, a driving valve, a swing arm, a valve plate, a sealing ring fixing seat and a sealing ring, wherein a feeding pipe is arranged at the top of the valve body; the sealing ring fixing seat is arranged at the bottom of the feeding pipe; a wear resistant sealing ring is arranged on the sealing ring fixing seat; a discharge opening is formed in the bottom of the valve body; a driving shaft is arranged on the side wall of the valve body and is arranged inside the valve body; two ends of the driving shaft penetrate through the valve body; one end of the driving shaft is linked with a sector-shaped air cylinder outside the valve body through a coupler; the swing arm is arranged on the driving shaft in the valve body and is connected with the valve plate; the wear resistant sealing ring is arranged on the valve plate; and the bottom of the feeding pipe is compressed and sealed with the valve plate through the wear resistant sealing ring. The pneumatic plate turning type powder body feeding valve disclosed by the utility model has the advantages of favorable sealing effect, long service life, high temperature resistance, wear resistance and easiness for overhaul and maintenance; and after the pneumatic plate turning type powder body feeding valve is worn, the pneumatic plate turning type powder body feeding valve can be continuously used by replacing the sealing ring fixing seat and the sealing ring. The pneumatic plate turning type powder body feeding valve disclosed by the utility model can be used for bilge pump feeding valves in pneumatic dust removing systems of coal-fired power plants.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of used inlet valve of fluidized pump in fly ash or other powder body malleation air-transport systems that is applicable to.
Background technology
At present, the coal-fired fly ash that produces of domestic thermal powerplant, most of malleation air-transport system that adopts is handled.The inlet valve that connects the storehouse pump in this system is one of critical component, and the domestic inlet valve principal mode that adopts has: 1, dome valve, and this valve seal is functional; Volume is little; But manufacturing cost is higher, and its rubber seal is damaged maintenance cost height after easily.2, gate valve; This valve drives valve plate is realized valve switch as linear slide on the sealing surface of porthole action through cylinder usually; Wear resisting property requirement and sealing property to contact surface are had relatively high expectations, and cause this type of valve expense more expensive, and the same high problem of back maintenance cost of damaging that exists.3, belljar valve, this valve in use because bell jar is in the dust inlet center, easily dust stratification and cause stopping up, poorly sealed etc.。
Summary of the invention
The purpose of the utility model is to solve at present domestic ubiquitous inlet valve expense high, not easy care, problem such as damage easily, a kind of good seal performance, long service life is provided, is easy to repair and maintenance and the lower Pneumatic reverse turning bed formula powder body inlet valve of expense.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Pneumatic reverse turning bed formula powder body inlet valve; It comprises valve body, cylinder, transmission shaft, swing arm, valve plate, seal ring permanent seat and seal ring, is provided with feed pipe at the valve body top, and the feed pipe bottom is provided with the seal ring permanent seat; On the seal ring permanent seat, be provided with the wear-resistant seal circle; Be provided with discharging opening in the valve body bottom, on body wall, be provided with transmission shaft, transmission shaft places valve inner and two ends to penetrate valve body; A transmission shaft wherein end links through coupler and the outer Fan shape cylinder of valve body; Be provided with swing arm on the transmission shaft in valve body and connect valve plate, on valve plate, be provided with the wear-resistant seal circle, wear-resistant seal circle pinch-off seal is passed through with valve plate in the feed pipe bottom.
The utility model has the advantages that: the seal ring permanent seat of feed pipe bottom is a detachable form, and when seal ring was worn, replacing seal ring or replacing seal ring permanent seat can continue to use, and whole unloading process operation easier is little, and speed is fast, for ease of maintenaince; Swing arm is provided with the bolt that is used to regulate the valve plate angle, when leak air, during poorly sealed situation, the sealing angle that can regulate valve plate through this bolt make valve adapt to various working; When transmission shaft rotated to end position, swing arm and vertical direction angle were between 7 ° to 9 °, have strengthened sealing property, when not enough, also can increase this angle through the mode of changing coupler like on-the-spot bleed pressure, guaranteed the air-tightness of valve; Valve plate is provided with circular steel plate and bolt is used to compress the wear-resistant seal circle, plays the effect of circle in the protection seal ring simultaneously, reduces wear.
