Problems solved by technology

[0002] The existing buoy type liquid level gauge usually adopts a closed buoy, and the weight of the buoy is not adjustable. When the specific gravity of the liquid in the container changes greatly, the liquid level gauge will fail; The fluctuation makes the buoy drift and tilt, which affects the accuracy of the liquid level indication; the ordinary pulley used is easy to rust and get stuck or even stuck, resulting in an error in the liquid level indication; generally there is no liquid level gauge, and the sensitivity of the liquid level indication is poor

Embodiment 1

[0014] Example 1 figure 1 , 3 Shown: a float type liquid level indicator device, including a container 7 filled with liquid; a support plate 3 is provided at the upper end of the container 7, and two pulleys 4 are installed on the horizontal line of the support plate 3, one of which is a pulley 4 Located inside the extension line of the side wall of the container 7, the other pulley 4 is located outside the extension line of the side wall of the stainless steel container 7; one end of the connecting line 2 is connected to the pontoon 1 in the container 7, and the other end after bypassing the pulley 4 is connected to the liquid level The liquid level indicator block 5 beside the scale 6 is connected; the liquid level scale 6 is installed on the outside of the side wall of the container 7 or is printed on the side wall of the container 7. The pontoon 1 is cylindrical and made of corrosion-resistant non-metallic materials; the pontoon 1 is composed of a cylinder body 10 and a cyli...

Embodiment 2

[0015] Example 2 such as figure 2 As shown: The float type liquid level indicator device of this embodiment is used for the liquid level measurement of ammonium molybdate solution; the ammonium molybdate solution is more expensive, and the top cover of the container 7 must not pass through the connection line of the liquid level device to prevent Impurities such as rainwater enter the storage tank to contaminate the solution. To this end, a beveled square tube 11 is provided on the upper side of the container 7, and the inner ring of the rolling bearing of the core of the pulley 4 is fixed on the support shaft of the inner wall of the beveled square tube 11. The buoy 1 is cylindrical and made of hard plastic, and the buoy cylinder body 10 and the cylinder cover 9 are connected by a sealed thread. Fill the buoy 1 with 45% volume of concentrated brine, put the buoy 1 vertically into the ammonium molybdate solution in the container 7, so that 1 / 2 of the height of the buoy 1 is i...

Abstract

The invention relates to a floating cylinder type liquid level indicating device. A supporting plate is arranged on a container, two pulleys are installed on the horizontal line of the supporting plate, one end of a connecting line is connected to a floating cylinder arranged in the container, the other end of the connecting line surrounds the steel pulleys, and is connected with a liquid level indicating block, and a liquid level ruler is installed on the outer wall of the container or is marked on the outer wall of the container in an engraving mode. The floating cylinder is composed of a cylinder body and a cylinder cover, wherein the cylinder body and the cylinder cover are connected through threads or a flange in a sealing mode, the core portion of each pulley is provided with a rolling bearing, and the inner race of each rolling bearing is fixed on a supporting shaft of the supporting plate. The connecting line is nylon thread, and the liquid level indicating block is an isosceles triangle. Scale marks of the liquid level ruler are drawn with fluorescent pigment so that a user can read the value of the liquid level at night. Due to the fact that a detachable structure is adopted by the floating cylinder of the floating cylinder type liquid level indicating device, the weight of the floating cylinder can be conveniently adjusted, and the floating cylinder type liquid level indicating device is applicable to liquid level indication of liquid with different specific gravity. Due to the fact that the rolling bearings are installed on the pulleys of the floating cylinder type liquid level indicating device, resistance of rotation is low, and the floating cylinder type liquid level indicating device is high in sensitivity.

Description

Technical field [0001] The invention relates to a liquid level indicator, in particular to a high-sensitivity float type liquid level indicator device. Background technique [0002] Existing float-type level gauges usually use closed floats, and the weight of the floats is not adjustable. When the specific gravity of the liquid in the container changes greatly, the level gauge will fail; when the weight of the floats is not appropriate, it is easy to cause the liquid level when the container enters. Fluctuation causes the float to drift and tilt, which affects the accuracy of the liquid level indication; the ordinary pulleys used are easy to rust and get stuck or even get stuck, resulting in liquid level indication errors; generally, there is no liquid level gauge, and the sensitivity of the liquid level indication is poor. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a high-sensitivity float type liquid level indicato...
