Abstract
The invention relates to an air-lock flap valve. The air-lock flap valve comprises an outer shell which is provided with a notch, wherein an examination cover plate which can close an opening of the notch is arranged at the opening of the notch, the notch is partially provided with a shaft, a shaft sleeve which is sleeved outside the shaft and a movement-weight part which is connected with the shaft and is arranged outside the outer shell; and a valve plate which is arranged inside the outer shell is connected onto the shaft. The notch is arranged on the outer shell, so that when relevant parts such as the shaft, the valve plate and the like are damaged and are required to repair and replace, the parts can be taken out from the notch by opening the examination cover plate. Compared with the traditional structural form, the air-lock flap valve is more convenient to examine and replace.
Description
Technical field
The present invention relates to the heavy hammer type Flap valve that a kind of rotation through valve plate comes control valve to open, close, but specifically design 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.
Summary of the invention
The objective of the invention 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 present invention's employing is for this reason: the present invention includes 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.
Advantage of the present invention is: the present invention offers 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.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the enlarged view of I portion among Fig. 1.
Among the figure 1 for frame, 2 for inner housing, 3 for valve plate, 4 for U-shaped flange, 5 attach most importance to hammer handle, 6 for weight, 7 for link, 8 for axle, 9 for axle sleeve, 10 for maintenance cover plate, 11 for seal washer.
Embodiment
Below in conjunction with accompanying drawing and concrete mode the present invention is described further:
Shown in accompanying drawing, the present invention includes frame 1, inner housing 2, valve plate 3, link 7, axle 8, axle sleeve 9, U-shaped flange 4, weight handle 5, weight 6, maintenance cover plate 10 and seal washer 11.The present invention opens U-lag on shell body 1; Inner housing 2 is fixing by bolt and shell body 1; Valve plate 3 is fixed on the axle 8 and by axle sleeve 9, U-shaped flange 4 by connector 7 and fixes at shell body 1U shape groove place; Maintenance cover plate 10 is connected with shell body 1 by bolt with seal washer 11, spools 8 outer end connection weight handle 5, fixing weight 6 on weight handle 5.
The present invention has U-groove bevel in the joint of axle 8 and frame 1, makes axle 8 and the valve plate 3 that is fixed together with axle 8 can pass through convenient dismounting and the replacing of notch.U-shaped flange 4 should be welded on frame 1 inboard, and corresponding with frame 1, axle sleeve 9.
Valve body front end of the present invention is provided with maintenance cover plate 10, and maintenance cover plate 10 and 1 of frame are provided with seal washer 11, connects fixing through bolt.
