The electric valve actuator is connected with a drive rod, and the drive rod is connected with a screw rod. The electric open-type gate valve is characterized in that the valve body comprises a left valve body and a right valve body, a fixed valve seat is arranged on the left valve body, a floating valve seat is arranged on the right valve body, and the two sides of the fixed valve seat are respectively and movably connected with a limiting baffle used for limiting the position of the valve plate. According to the electric open-type gate valve, the limiting baffles are additionally arranged, accurate positioning of the valve plate which is moved to the through hole position from the blind hole position is guaranteed, the accurate positioning can be achieved without repeated adjustment, the requirement for operating personnel is lowered, and meanwhile cost is saved.
Description
Technical field
The utility model relates to valve technology field, in particular: it relates to a kind of electronic open gate valve.
Background technique
The purposes of open gate valve is in industrial pipeline, to play a part to open and cut off, and is widely used on the pipeline of the industrial departments such as metallurgy, oil, chemical industry, coal gas.
The working principle of open gate valve is the working state of push-pull valve in through hole, and sealing pair clamps, and flowing medium can pass through, and when needs cut off, the action of valve is as follows: unclamp, move, clamp.Unclamp and be to prepare for the movement of valve plate, because valve plate must gappedly could move, the object of unclamping is exactly in order to manufacture gap, movement is to make valve plate move lead to the hole site by blind hole position, after arriving blind hole position, stop, clamping, screw mandrel counterrotating, eliminate the gap of unclamping rear generation, make the sealing pair close contact between valve body and valve plate, reach media flow and the object that prevents external leakage in cutting out pipeline, vice versa.So how in moving process, realize by blind hole position the accurate location to lead to the hole site, existing technology realizes an accurately location by operator's experience often, so often just needs repeatedly could realize partition, is therefore badly in need of improving.
Model utility content
The deficiency existing for prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, easy to operate and can realize the electronic open gate valve of accurate location.
For achieving the above object, the utility model provides following technological scheme: a kind of electronic open gate valve, comprise valve body, be located at valve plate, electric device for valve, the clamp device in valve body and the rail brackets moving for valve plate, described electric device for valve is connected with drive link, described drive link connection wire rod, described valve body includes left valve barrel, right valve barrel, described left valve barrel is provided with fixed valve base, described right valve barrel is provided with floating valve seat, and described fixed valve base both sides are all connected with the postive stop baffle that limits valve plate position.
By adopting technique scheme, Electric actuator drives clamp device to realize unclamping of floating valve seat and guarantees gap, valve plate moves on rail brackets, when valve plate moves to lead to the hole site by blind hole position and at once, realize the media flow in cutting out pipeline, postive stop baffle is moved to the position of dotted line from the position of original solid line, in valve plate movement process, arranging of postive stop baffle guarantees that valve plate is moved to the accurate location of lead to the hole site by blind hole position, without repeatedly regulating and just can reach, fall at the end requirement to operator, saved cost simultaneously.
The utility model is further set to: described valve plate is provided with sensor near postive stop baffle one side.
By adopting technique scheme, postive stop baffle is guaranteed the accurate location of valve plate, when valve plate moves to the position at postive stop baffle place, sensor is subject to vibration induction and sends signal then by operator's throttle down Electric actuator, sensor improves closed assurance precision, the damage of avoiding screw mandrel idle running to cause, the L-shaped simple baffle plate setting operation of postive stop baffle is convenient, cost-saving.
The utility model is further set to: on described electric device for valve, be provided with manual turntable.
By adopting technique scheme, electric device for valve is provided with manual turntable, realizes the auto-manual of transmission, and applicability is extensive, more meets user's demand.
The utility model is further set to: between described floating valve seat and described valve plate, be provided with bellows.
By adopting technique scheme, the setting of bellows can be guaranteed the shaft seal of valve plate in moving process.
The utlity model has following advantage: increase and be provided with postive stop baffle, guarantee that valve plate is moved to the accurate location of lead to the hole site by blind hole position, without repeatedly regulating and just can reach, fallen at the end requirement to operator, saved cost simultaneously.
