Abstract
The utility model discloses an inlet valve with a movable sealing seat, which comprises a valve body, a cylinder, a turnover plate and a transmission shaft, wherein the top of the valve body is provided with a feeding hole, the bottom of the valve body is provided with a discharging hole, and the side wall of the valve body is provided with the cylinder; the output shaft of the cylinder is connected with one end of the transmission shaft; the other end of the transmission shaft is arranged in the valve body after penetrating through the outer wall of the valve body; and the transmission shaft in the valve body is provided with the turnover plate which is provided with a turnover plate sealing ring. The inlet valve also comprises a movable sealing seat and a sealing seat sealing ring; the top end of the movable sealing seat is movably sealed on the feeding hole, and the bottom end of the movable sealing seat is provided with the sealing seat sealing ring; and the bottom end of the movable sealing seat is movably compacted and sealed with the sealing seat sealing ring through the turnover plate sealing ring. The utility model has the advantage that because the feeding hole of the inlet valve is provided with the movable sealing seat, the inlet valve can be continuously used by only replacing the movable sealing seat when the sealing ring is worn out and the valve seat is damaged, the service life of the inlet valve is prolonged, and the inlet valve is easy to overhaul and maintain.
Description
Technical field:
The utility model relates to a kind of pneumatic inlet valve, relates in particular to a kind of inlet valve that has the movable sealing seat.
Background technology:
At present, the flying dust that domestic newly-built thermal electric generation unit produces nearly all adopts electric dust collector or bag dust collector to collect in the ash bucket, concentrates accumulating to grey storehouse flying dust by pneumatic conveying principle then, carries out post-processed again.
In air-transport system, the parts of most critical are inlet valves.
Existing inlet valve in use exists rubber seal easy to wear, and service life is short; And rubber seal is difficult for very first time discovery after wearing and tearing, and cause inlet valve to reveal, damage the sealing surface of valve seat, because the locus of sealing surface of seat and the particularity of structure, sealing surface of seat can't be repaired after damaging at all, causes inlet valve to damage and scraps.
The utility model content:
The purpose of this utility model is to provide a kind of long service life, is easy to the inlet valve that has the movable sealing seat of repair and maintenance.
The utility model is implemented by following technical scheme: a kind of inlet valve that has the movable sealing seat, it comprises valve body, cylinder, turnover panel and transmission shaft, be provided with inlet point at described valve body top, be provided with discharging opening in described valve body bottom, on described body wall, be provided with described cylinder, the output shaft of described cylinder is connected with described transmission shaft one end, the other end of described transmission shaft passes described valve outer wall and places in the described valve body, be provided with described turnover panel on the described transmission shaft in described valve body, on described turnover panel, be provided with the turnover panel seal ring, it also comprises movable sealing seat and seal receptacle seal ring, described movable sealing seat top movable sealing is on described inlet point, be provided with described seal receptacle seal ring in described movable sealing seat bottom, described movable sealing seat bottom and described turnover panel are by described turnover panel seal ring and the movable pinch-off seal of described seal receptacle seal ring.
Advantage of the present utility model: the inlet point place at inlet valve is provided with the movable sealing seat, works as ring wear, after the valve seat damage, only needs to change this valve of movable sealing seat and can continue to use, and has increased the service life of inlet valve, and inlet valve is easy to repair and maintenance simultaneously.
