Abstract
The utility model discloses a totally-enclosed fan-shaped blind flange valve, which includes a valve body; a convertible shutter is arranged on the valve body; a half of the convertible shutter is a blind plate and the other half is a pore plate; the convertible shutter is connected with a rotary mechanism; and valve covers are arranged on two sides of the valve bodies for sealing the convertible shutter inside. The utility model has advantages of reasonable structure; the convertible shutter is completely enclosed; and in the conversion operation, the fluid in the valve body is prevented from leaking to the external environment.
Description
Technical field:
The utility model relates to a kind of valve.
Background technique:
Existing blank-plate valve, its convertible flashboard can be taken a part of fluid in the valve body out of when conversion work, leak in external environment.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can not cause the totally-enclosed fan-shaped blank-plate valve of escape of liquid in the valve body.
Technical solution of the present utility model is:
A kind of totally-enclosed fan-shaped blank-plate valve comprises valve body, and the reversible type flashboard is set on the valve body, half of reversible type flashboard is blind plate, second half is an orifice plate, and convertible flashboard is connected with swirl gear, it is characterized in that: the valve body both sides are provided with convertible flashboard are sealed in wherein valve gap.
Valve body with valve body is connected with the fastening device that convertible flashboard clamps.Be provided with on the valve gap and diffuse mouth.
The utility model is rational in infrastructure, and convertible flashboard is by complete closed, during its conversion work, can not cause that escape of liquid is in external environment in the valve body, and environmental protection and energy saving make the harmful gas zero-emission, reduce and pollute; The utility model is safe and reliable, and structural member has been realized littler than similar valve span, so rigidity is good, seals more reliable, safety; Simple to operate, easy to maintenance.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Fig. 2 is the sectional drawing of Fig. 1.
Fig. 3 is that the A of Fig. 2 is to view.
Embodiment:
A kind of totally-enclosed fan-shaped blank-plate valve comprises valve body 1, and reversible type flashboard 2 is set on the valve body, half of reversible type flashboard is blind plate, second half is an orifice plate, and convertible flashboard is connected with swirl gear 3, and the valve body both sides are provided with convertible flashboard is sealed in wherein valve gap 4.Valve body with valve body is connected with the fastening device 5 that convertible flashboard clamps.Be provided with on the valve gap and diffuse mouth 6.Also have sewage draining exit 7, clean-up port 8, manhole 9 among the figure.
Fastening device adopts Worm gear case and gearbox drive.
When driving valve, valve body moved right during fastening device drove, and reversible type flashboard (or claiming valve plate) band keeps given distance from valve body sealing surface with the both sides sealing face simultaneously, and swirl gear drives the rotation of reversible type flashboard, valve open; Fastening device clamps, and valve body is moved to the left in the drive, realizes valve opening, opens the valve process and finishes.When closing valve, with above action, just the valve plate revolution is reverse, and valve closing effectively cuts off media such as coal gas, places in the media discharge band atmosphere.
