Technical field

The utility model belongs to mud cleaning system technical field, fills more particularly to a kind of slurry tank Liquid level It sets.

Background technique

Mud circulating tank is suitable for storage mud, guarantees mud circulating purification, in mud circulating tank liquid level it is too low when meeting The phenomenon that causing slurry tank to drain will seriously damage ring conveying pump group when the mud in slurry tank is drained, it is therefore desirable to artificial real When concern mud circulating tank in liquid level height, in order to avoid cause conveying pump group damage；Applicant and Shen on December 30th, 2015 Please a kind of mud circulating tank liquid level automatic balancing device, in off position, in the floating ball rod of the liquid level automatic balancing device The center of the heart and valve plate is in the same plane, opens under the action of floating ball and counterweight around valve shaft downlink when liquid level decline Angle gradually increases.Initial opening is smaller in actual use, can not quickly supplement slurry, and leading to slurry, supply falls short of demand, The phenomenon that draining；Another formal structure is equipped with limit ring flat-plate and counterweight, makes that its structure is complicated, and production cost is relatively high.

The utility model provides one kind angle that compared to the prior art floating ball only needs to rotate very little and can obtain thus Obtain bigger valve plate opening degree；The slurry tank fluid level control device for realizing quickly supplement slurry, without on duty, guarantee mud Circulation tank level is maintained at the slurry tank fluid level control device of a comparison constant altitude.

Summary of the invention

The utility model is to solve technical problem present in well-known technique and provide that a kind of structure is simple, realizes and quickly mends The slurry tank fluid level control device of slurry is filled, without on duty, it is permanent that guarantee mud circulation tank level is maintained at a comparison Determine the mud circulating tank liquid level automatic balancing device of height.

The utility model is adopted the technical scheme that solve technical problem present in well-known technique:

A kind of slurry tank fluid level control device, including floating ball, valve rod, valve plate, valve shaft；Wherein the valve shaft is mounted on The center line of the outlet port of slurry tank overfall nozzle, the valve shaft is vertical with overfall nozzle, it is characterised in that: in overfall nozzle Inclined valve plate is installed on the interior valve shaft, valve rod attachment base, institute are installed in the described valve shaft one end in the outside of overfall nozzle It states and connects valve rod on valve rod attachment base；The axis of the valve rod center line and valve plate is equipped with angle；The outer end of the valve rod connects Connect floating ball；When valve rod center line is in a horizontal state, inclined valve plate outer edge and overfall internal wall of pipe orifice palette, valve at this time Plate is in close state；When the center line of valve rod is located at below horizontal center line, the outer edge and overfall internal wall of pipe orifice of valve plate Sealing forms return flow line.

The valve rod attachment base includes attachment base ontology, and the attachment base ontology is equipped with valve shaft mounting hole, the company The lower section of joint chair ontology is equipped with the preload slot being connected to valve shaft mounting hole, is vertically equipped on pre-tightening attachment base ontology described in slot side The valve rod mounting hole of perforation；Valve rod is inserted in the valve rod mounting hole, the end of the valve rod is equipped with thread segment, in attachment base sheet Locking nut is fitted on the thread segment of valve rod described in the two sides of body.

The section of the slurry tank inlet pipe mouth is square structure；The end surface shape square structure of the valve plate.

The utility model has the advantages and positive effects of: by adopting the above technical scheme due to the utility model, working as liquid Position can jack up floating ball when increasing, and drive valve plate overturning by valve rod, so that the return flow line of valve plate and inlet pipe mouth reduces, stream Amount becomes smaller, and extra slurry can be flowed away by the other pipelines being connected to overfall nozzle.When liquid level decline, floating ball is under self weight Drop drives valve plate to turn counterclockwise by valve rod, so that the return flow line of valve plate and overfall nozzle increases, flow becomes larger, due to Valve plate design has initial angle, and the angle that floating ball only needs to rotate very little is obtained with bigger valve plate opening degree, in this way with Moment biggish aperture may be implemented compared to when opening in the design of existing horizontal valve plate, and then quickly returning for slurry may be implemented It mends；Do not decline as supply amount and discharge amount can be maintained at certain liquid level and do not rise, so not will cause dry pulp or Overflow slurry, which can accomplish unattended, the constant safe operation of the equipment such as the delivery pump that adequately protects.In addition, the utility model Also have many advantages, such as that structure is simple, easy to install and use.
