Abstract
A wedge type double gate valve comprises a main shutter, an auxiliary shutter and a lifter, which is characterized in that: the main shutter adopts a parallel structure and the auxiliary shutter adopts a wedge structure. At a closing state, the auxiliary shutter uses wedge structure and is inclined to realize reliable seal at the shutter and the auxiliary shutter as seal on the valve body, and at an opening state, the auxiliary shutter adopts the wedge structure, the seal surfaces have no relative sliding, the main shutter is used as left and right seals to reduce the transmission torque, therefore, the shutter can be opened flexibly and the surface of the shutter is hard to form scale, thereby resolving the problems such as reduced seal performance and clamping and prolonging the service life of the shutters.
Description
Technical field
The utility model relates to a kind of flashboard valve, particularly a kind of Wedge gate valve that is used for conveying electrolyte solutions uses such as power plant, aluminium manufacturer, coal washery, molybdenum ore.
Technical background
At present in the working procedure of metallic ores such as power plant, aluminium manufacturer, coal washery, molybdenum ore, tungsten ore, be used to carry the valve of medium systems such as slurry, slag mostly to be parallel flashboard structure, in valve rod lifting, landing process, be easy to form fouling on the valve plate surface, cause problems such as valve seal decreased performance, clamp, can produce continuously normal operation to it and affect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art exactly and a kind of wedge-type double-gate valves is provided, and is a kind of novel gate valve of optimizing structure.
For achieving the above object, the utility model adopts following scheme: a kind of wedge-type double-gate valves, and it comprises main gate-board, auxiliary gate-board and lifting gear, it is characterized in that main gate-board adopts parallel structure, auxiliary gate-board adopts wedge-shaped structure.
In off position down,, have the angle of inclination, make on flashboard and the valve body and can obtain tight reliable sealing performance as the auxiliary gate-board that seals because auxiliary gate-board adopts wedge-shaped structure.Under opening state, flashboard and valve body are instantaneous to be left, in the opening process,, there is not slide relative between the sealing surface because auxiliary gate-board adopts wedge-shaped structure, sealing about main gate-board is done, reduced the transmission torque greatly, made gate opening flexible, the flashboard surface also is difficult for forming fouling, solve problems such as valve seal decreased performance, clamp, prolonged flashboard working life.
Description of drawings
Fig. 1 is that the utility model descends structural representation in off position
Fig. 2 is the utility model structural representation under opening state
Wherein 1 is that valve seat, 2 is that auxiliary gate-board, 3 is main gate-board.
Embodiment
Fig. 1 is that valve is following in off position, because auxiliary gate-board 2 adopts wedge-shaped structures, has the angle of inclination, makes on flashboard and the valve body and can obtain tight reliable sealing performance as the auxiliary-valve that seals.Fig. 2 is that valve is under opening state, flashboard and valve body are instantaneous to be left, in the opening process,, there is not slide relative between the sealing surface because auxiliary gate-board 2 adopts wedge-shaped structure, sealing about main gate-board 1 is done, reduced the transmission torque greatly, made valve opening flexible, the flashboard surface is also less scaling, solve problems such as valve seal decreased performance, clamp, prolonged flashboard working life.
