Abstract
The utility model relates to a novel air lock flap valve. The air lock flap valve comprises an outer shell provided with a notch, wherein an opening of the notch is provided with a maintenance cover plate used for closing the opening of the notch; the notch is provided with a shaft, a shaft sleeve which is sleeved outside the shaft, and a heavy hammer which is connected with the shaft and positioned outside the outer shell; and the shaft is connected with a valve plate positioned in the outer shell. According to the novel air lock flap valve, the outer shell is provided with the notch, so that when relevant components such as the shaft and the valve plate are damaged and required to be maintained and replaced, the maintenance cover plate can be opened, and the relevant components can be taken out of the notch; and compared with the conventional structural form, the novel air lock flap valve can be maintained and replaced conveniently.
Description
Technical field
The utility model relates to the heavy hammer type Flap valve that a kind of rotation through valve plate comes control valve to open, close, but specifically designs a kind of integral demounting formula weight lock wind Flap valve.
Background technique
Flap valve extensively uses as a kind of feeding device in industries such as electric power, metallurgy, coal, chemical industry, cement; Because the axle sleeve and the housing joint housing of the heavy hammer type Flap valve in the conventional construction seal; So can only extract axle during maintenance earlier out dismantles valve plate again; Make valve be not easy to maintenance and dismounting like this, also be not easy to the installation of valve plate, the working life of having reduced valve.
The model utility content
The purpose of the utility model is for the ease of valve maintenance and dismounting in use, but a kind of integral demounting formula weight lock wind Flap valve is provided.
The technological scheme of the utility model employing is for this reason: the utility model comprises the frame that is provided with notch; The opening of notch is established the maintenance cover plate that it is closed, the heavy hammer part that is in the frame outside that said slot-open-section is equipped with axle, is set in the outer axle sleeve of axle and is connected with axle; Be connected with on the axle and be in the inner valve plate of frame.
Said notch is established the flange corresponding with it, and said maintenance cover plate is connected on the flange through bolt.
Said notch is the U-groove bevel mouth.
The utility model has the advantages that: the utility model is offered notch on frame; Working as associated components such as axle, valve plate like this is damaged; When needing maintenance and replacing; Can corresponding parts be taken out from notch through opening the maintenance cover plate, it is compared its maintenance of traditional structural type, changes greatly convenient convenience.
