Abstract
The utility model discloses an emptying valve which comprises a valve base (1), a gasket (2), a valve body (3), a flange cover (4), a valve pillar (5), a nut (6), a valve cover (7), a valve rod nut (8), a bearing (9), a bearing gland (10), a driving device (11), a valve clack (12), a gland (13), bisect rings (14), a valve rod (15), padding (16), a packing gland (17), a rotating prevention plate (18) and a bolt (19). The flange cover (4) is connected with an opening on one side of the valve body (3) through the bolt and the gasket, the valve clack (12) is connected with the valve rod (15) through the gland (13) and the bolt, and openings on bottom sides of the valve base (1) and the valve body (3) are connected together through the bolt and the gasket (2). When the valve clack is damaged, users only need to replace the valve clack instead of the whole valve body, so that cost is reduced, and scab in the valve body can be cleaned easily.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of discharging valve.
Background technique
Discharging valve is mainly used in the bottom discharging, blowing, sampling of reactor, storage tank and other container and turn-offs operation without the dead band.Be welded in the bottom of storage tank and other container by means of the valve flange in the bottom, therefore eliminate processing medium usually in the residual phenomena of container mouth.Discharging valve is put bottom structure and is designed to platybasic type according to the needs of actual conditions, and valve body is V-type, and lifting and the two kinds of working method flaps that descend are provided.
Easily scab in the valve body of traditional discharging valve, remove the difficulty that scabs, affect the normal use of discharging valve; And flap is fragile, needs to change whole valve body, has improved work difficulty and cost.
Summary of the invention
The above-mentioned shortcoming and defect that exists in order to solve prior art, the utility model provides a kind of discharging valve, and the utility model only needs to change flap after flap damages, and need not to change whole valve body, has reduced cost; And easily remove scabbing in the valve body.
The utility model is achieved through the following technical solutions:
A kind of discharging valve, comprise valve seat, pad, valve body, blind flange, valve rod, nut, valve gap, Stem Mut, bearing, bearing gland, drive unit, flap, gland, split annulus, valve rod, filler, Gland, torsional stop and bolt, described blind flange is connected with a side opening of described valve body with pad by bolt, described flap and described valve rod link together by described gland and bolt, and the bottom side openings of described valve seat and described valve body links together by bolt and pad.
Preferably, the material of described pad is Expanded graphite and stainless steel.
The utility model flap and valve rod are detachable to link together, and only need dismantle and change flap after flap damages, and need not to change whole valve body, has reduced cost; After scabbing in the valve body of discharging valve, can remove scabbing in the valve body by detachable blind flange.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The present invention is described in detail below in conjunction with specific embodiment.Following examples will help those skilled in the art further to understand the present invention, but not limit in any form the present invention.Should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make some distortion and improvement.These all belong to protection scope of the present invention.
Discharging valve as shown in Figure 1, comprise valve seat 1, pad 2, valve body 3, blind flange 4, valve rod 5, nut 6, valve gap 7, Stem Mut 8, bearing 9, bearing gland 10, drive unit 11, flap 12, gland 13, split annulus 14, valve rod 15, filler 16, Gland 17, torsional stop 18 and bolt 19, blind flange 4 is connected with a side opening of valve body 3 with pad by bolt, flap 12 connects by gland 13 and bolt with valve rod 15, and the material of pad 2 is Expanded graphite and stainless steel.
The flap of the present embodiment and valve rod are detachable to link together, and only needs to change flap after flap damages, and need not to change whole valve body, has reduced cost; After scabbing in the valve body of discharging valve, by detachable blind flange, easily remove scabbing in the valve body.
