Abstract
The utility model relates to an improved liquid level display device, which solves the problems that a communication type glass pipe level gauge is not safe enough and can not meet fire resistance requirement. The utility model is mainly composed of a guide rod, floating balls which can slide up and down along with the guide rod, strong magnets arranged on the floating balls, and a transparent floating mark pipe which is filled with liquid and arranged on the outside of a liquid can and a magnetic floating mark arranged in the pipe. When the floating balls slide up and down along with the lifting and lowering of the liquid level in the liquid can, the strong magnets of the floating balls attract the magnetic floating mark to move up and down; the position of the floating balls and the liquid level in the liquid can be known by observing the position of the magnetic floating mark; the transparent floating mark pipe is not filled with fuel or corrosive liquid, and is not communicated with the liquid can, and therefore, the utility model completely meets the fire resistance requirement, and the utility model is safe.
Description
The utility model relates to a kind of improved liquid level display device, particularly a kind of non-magnetic conduct liquid tank magnetic induction float type liquid level gauge.
Communication type glass-tube liquid level meter safety inadequately is installed on the basin of fuel oil or corrosive liquids, if broken glass tube because of carelessness, fuel oil or corrosive liquids will spill, and cause fire or corrosivity destruction easily, can not satisfy fire prevention, safety requirements.
The purpose of this utility model provides non-magnetic conduct liquid tank that a kind of receiver of suitable non-magnet material system installs and uses with magnetic induction float type liquid level gauge.Even fuel oil or corrosive liquids in the clear glass tracheal rupture, flow container can not flow out yet.It can satisfy fire prevention, safety requirements, and is very reliable, and cost is not high.
The utility model is achieved in that in a non-magnetic conduct liquid tank and near a jar place, limit ball float, the guide rod device with anti-rotation structure is housed, guide rod is vertical or be approximately perpendicular to surface level, guide rod is one to two, guide rod is equipped with ball float outward, can allow ball float along the upper and lower slippage of guide rod, simultaneously can prevent that again ball float from rotating around guide rod, powerful magnet is housed on the ball float, the transparent float tube parallel with guide rod is equipped with in the outer place near the ball float magnet of flow container, be filled with liquid in the pipe and be placed with the magnetic buoy, the proportion of magnetic buoy is near the proportion of liquid in pipe.
Ball float can be enclosed within guide rod outer (being that guide rod passes ball float), also can be contained in the guide rod side.
In order to make the powerful magnet on the ball float keep strong magnetic effect, be provided with the floating ball preventing rotation structure to the magnetic buoy in the float tube.When with a guide rod, ball float is enclosed within guide rod outer (being that guide rod passes ball float), anti-rotation structure is: the shape of the xsect of the xsect of guide rod and ball float through hole causes non-positive circle, and big or small, concavo-convex interworking, and making guide rod block ball float from horizontal direction can not rotate.When with two guide rods, anti-rotation structure is: ball float is stuck between two guide rods, can allows ball float along the upper and lower slippage of guide rod, but can not rotate and can not break away from guide rod around guide rod.
In order to reduce the resistance that the buoy ascending, descending is moved in the topping up float tube, make the proportion of the proportion of magnetic buoy near liquid in pipe.When flow container was slack tank, the magnetic buoy was in the pipe end.So the proportion that is slightly larger than liquid in pipe with the proportion of magnetic buoy is the best.
Ball float is fabricated to good with non-magnet material.
When ball float with the liquid level ascending, descending during upper and lower slippage, the magnetic buoy in the transparent float tube also moves along with upper and lower, the liquid level position in the flow container is just known in the position of observing the magnetic buoy.
The transparent material manufacturing of transparent float tube is as clear glass, transparent plastic ... Deng.
Class of liquids in the transparent float tube does not have strict regulations, as: common oils, water, lubricating fluid ... Deng can, be good with lubricating fluid, but its viscosity is all unsuitable big, also should not be with inflammable or corrosive liquid.
Advantage of the present utility model: it is a kind of direct-reading liquid level gauge.Be not communicated with between the transparent float tube of topping up and the flow container, even float tube breaks, the just small amount of liquid of this pipe of outflow, and be not fuel oil or corrosive liquids.The more important thing is that the liquid that can not in the flow container flows out, thus as safe as a house reliable, can satisfy fire prevention and safety requirements, cost is not high yet.It is fit to install and use with the flow container of non-magnet material manufacturing.
Be described further below in conjunction with drawings and Examples:
Fig. 1 is the partial sectional view (during a guide rod) of the utility model front view;
Fig. 2 is the synoptic diagram (embodiment 1) of shape of cross section of ball float, the guide rod of Fig. 1;
Fig. 3 is the synoptic diagram (embodiment 2) of shape of cross section of ball float, the guide rod of Fig. 1;
Fig. 4 is the partial sectional view (during two guide rods) of the utility model front view;
Fig. 5 is the A-A cut-open view of Fig. 4.
Embodiment 1:
As Fig. 1,2, one section pipe that internal diameter is bigger slightly than ball float is adorned near a jar limit in flow container top in stainless steel (in the non-magnet material a kind of) system, weldering one flange pedestal is with fixing upper flange 7 on pipe, the guide rod 1 that has square cross section in upper flange weldering one, a holder 8 is adorned in the lower end of the guide rod position at the bottom of flow container, the ball float 2 that square through hole is arranged is enclosed within outside the guide rod, then the guide rod that is with ball float is inserted in the holder.Ball float can the upper and lower slippage with the liquid level ascending, descending, but can not rotate.Powerful magnet 3 is equipped with in the ball float outside, and there is the transparent float tube 4 that is filled with lubricating fluid 5 parallel with square guide rod in the outer place near the ball float magnet of flow container, places magnetic buoy 6 in the liquid, and it can be that the dress small magnet forms in a hollow bead of stainless steel.The proportion of this magnetic buoy is slightly larger than the proportion of liquid in pipe.Kicker magnet in the stainless steel flow container on the ball float just attracts the interior magnet of the bead of float tube and drives bead.When the ball float of flow container with the liquid level ascending, descending during upper and lower slippage, the bead of float tube also moves along with upper and lower.Observe the position of bead (being the magnetic buoy in this example) in the transparent float tube and just know the position of flow container inner float ball and the height of liquid level.
As Fig. 1,3 on the basis of embodiment 1, the shape of cross section that changes guide rod is an isosceles triangle, the shape of cross section that changes the ball float through hole is a rectangle, and the 3rd limit of isosceles triangle is slightly shorter than the long edge lengths in the rectangle, and the point of the angle of two waists is pressed close to rectangular another long limit.Like this, ball float can not rotate around guide rod.
Embodiment 3:
, be symmetrical in and fix two guide rods 1 perpendicular to surface level on the center of circle and the spacing greater than ball float 2 diameters in the bottom surface of upper flange 7 as Fig. 4,5, the xsect of guide rod is circular.Symmetry is fixed two annulus 9 on ball float 2 diameters, and each annulus is enclosed within outside the guide rod, and like this, ball float is contained in two guide rod sides, and the round tube inside diameter of mounting flange pedestal is greater than the distance between the two guide rod outermost.Like this, ball float also can be with the liquid level ascending, descending of flow container, but can not rotate around guide rod.
