With the adoption of the magnetic liquid level meter, the requirements on pressure and the buoyancy are met; and the magnetic liquid level meter with the probe is simple in structure, has the effects of high precision, high security and the like, and is applicable for wide popularization.
Description
Technical field
The utility model relates to the measurement of liquid level, is specifically related to a kind of indicating device with magnetic operator.
Background technology
Liquid level gauge is widely used on the various containers such as tower, groove, jar, still and boiler; Different according to structure; The liquid level gauge type is divided into glass tubular type, glass plate type, magnetic, buoy (tube) formula; Wherein the magnetic liquid level gauge adapts to the level gauging under the conditions such as high temperature, high pressure, corrosivity, and therefore concrete security is reliably at home and abroad generally used.
The spar structures of traditional liquid level meter is cylindrical, and Media density is more little, and the length that floating drum requires is long more, and the pressure that bears is more little, otherwise just can not float, and easy jam.Because for magnetic fluid level gauge, density and pressure are contradiction.When having satisfied the pressure requirement, floating drum is not because of abundant overweight can floating.On the contrary, when having satisfied buoyancy, floating drum can't stand pressure because of too frivolous holding.The occasion too little for fluid to be measured density, that pressure is too high can't be used.And the traditional liquid level meter can only reach the indication liquid level purpose, can not realize controlling automatically liquid level.
Summary of the invention
For solving the defective that exists in the background technology, the utility model provides a kind of can satisfy the pressure requirement, can satisfy buoyancy again, and is provided with the magnetic fluid level gauge of probe.
For realizing above-mentioned purpose, the utility model adopts following technological means: have the magnetic fluid level gauge of self-checking device, comprise cylindrical shell, fluid level gauge and probe.
Be provided with ball in the said cylindrical shell; Ball inside is provided with the toroidal magnet that radius is slightly less than the cylindrical shell radius; Cylindrical shell is provided with the fluid level gauge with toroidal magnet magnetic force coupling outward, the other probe that is provided with of this fluid level gauge, the opposite side of cylindrical shell respectively be provided with up and down with cylindrical shell together with last connecting leg and following connecting leg.
Said fluid level gauge comprises magnetic ball and rule, and the magnetic ball is arranged in the rule, and said magnetic ball is made up of the magnetic hemisphere of two different colours, and one of them magnetic hemisphere is red, and another magnetic hemisphere is white.
Said probe is made up of high liquid-level probe and low liquid-level probe.
The said connecting leg of going up respectively is provided with a stop valve with following connecting leg.
Beneficial effect:1. the utility model adopts ball inside to establish the toroidal magnet that radius is slightly less than the cylindrical shell radius, not only has good bearing capacity, and can satisfy required buoyancy, is applicable to high pressure, the use of low-density occasion; And ball can not cause the jam phenomenon when rotating yet, and can not have influence on the degree of accuracy of fluid level gauge.
2. because crown radius is slightly less than the cylindrical shell radius, make distance shrinkage between toroidal magnet and the magnetic ball, thereby can make magnetic ball flexible overturning, improved the accuracy of this liquid level gauge.
3. this magnetic fluid level gauge is provided with probe, senses liquid level when too high when high liquid-level probe, and signal reaches the CS place of inlet, and inlet will be closed automatically, senses liquid level when low liquid-level probe and crosses the low inlet of then opening automatically.
4. this magnetic fluid level gauge is simple in structure, has accurate height, effect such as safe, is suitable for extensive popularization.

Embodiment
Embodiment 1
The magnetic fluid level gauge that has self-checking device comprises cylindrical shell 1, fluid level gauge 2 and probe.
Be provided with ball 3 in the said cylindrical shell 1, ball 3 inside are provided with the toroidal magnet 6 that radius is slightly less than cylindrical shell 1 radius; The cylindrical shell 1 outer fluid level gauge 2 that is coupled with toroidal magnet 6 magnetic force that is provided with; Said fluid level gauge 2 comprises magnetic ball 7 and rule 8, and magnetic ball 7 is arranged in the rule 8, and said magnetic ball 7 is made up of the magnetic hemisphere of two different colours; One of them magnetic hemisphere is red, and another magnetic hemisphere is white; These fluid level gauge 2 other high liquid-level probe 9 and low liquid-level probes 10 of being provided with; The opposite side of cylindrical shell 1 respectively be provided with up and down with cylindrical shell 1 together with last connecting leg 4 and following connecting leg 5, and go up connecting leg 4 and following connecting leg 5 respectively is provided with a stop valve.
The fluid level gauge 2 interior magnetic ball 7 original states fronts that the utility model has the magnetic fluid level gauge of self-checking device are white; During work; The cylindrical shell 1 of this magnetic fluid level gauge is connected through last connecting leg 4 and following connecting leg 5 and the container that fluid to be measured is housed, and when adding fluid to be measured toward container is interior, fluid to be measured enters in the cylindrical shell 1 from connecting leg; Ball 3 goes up and down with the liquid level height after receiving buoyancy function, and toroidal magnet 6 makes said magnetic ball 7 that 180 ° of upsets take place through magnetic coupling interaction; Because said magnetic ball 7 is the spheroids that have red, white two hemisphere synthetic; The meeting outside fluid level gauge 2 changes color after 180 ° so overturn, and when promptly liquid level rose, magnetic ball 7 became red face by white face; When liquid level descends; Then magnetic ball 7 becomes white face by red face, and the dichromatism intersection promptly is the height of liquid level, thereby can realize that liquid level shows; When in container, adding liquid, when liquid level rises to the position that is provided with high liquid-level probe 9, after high liquid-level probe 9 is sensed, signal is reached the CS place of inlet, inlet is closed automatically; Do not add liquid after a period of time to container, when liquid level drops to low liquid-level probe 10 positions, after low liquid-level probe 10 is sensed, signal is reached the CS place of inlet, inlet is opened automatically container is carried out liquid feeding.
