Abstract
The utility model installs a tthermosensitive sensor element (7) in a conduit pipe (1) for automatically and continuously detecting the liquid temperature. The relative position of a reed tube (4) is fixed by a non-magnetic collapsible clamp holder (10) for providing convenience for frequently adjusting the liquid level. The utility model is suitable for oils, chemical liquid and other large containers, and the liquid level can be used for temperature control, detection and alarm.
Description
The utility model relates to liquid level and temperature detects automatically, especially the temperature alarming liquid level detector.
In industry, communications, construction work, the Detection ﹠ Controling of tank fill level height seem day by day important.Especially in metallurgy, chemical industry, oil, light textile, food industry and underground works, public urban operating mechanism, many (height) layer residential houses, the Detection ﹠ Controling of liquid level have become indispensable technological means.
Common Level Detection and control all with the variation of certain physical parameter, as the actuating signal of sensing element, constitute a series of Level Detection instrument." factory uses electrical equipment handbook (supplementary copy) (hydraulic and electric engineering publishing house in July nineteen ninety) always a kind of UQK type Level Detection controller is provided.
This instrument places the more piece threaded sleeve below the liquid level, is provided with a plurality of tongue tubes in its pipe.When the ball float of interior dress magnet steel fluctuated with liquid level, tongue tube was influenced by the magnetic force size, produced different actions, thereby sensor output resistance is changed, and caused that bright the putting out of light emitting diode shows tested liquid level.When liquid level arrived predetermined altitude, indicator gauge sent joint signal, the start-stop of control motor, liquid pump, thus keep liquid level within limits.
This instrument can only detect the liquid level height, there is no the function that temperature shows, thereby the scope of application is restricted.To the fluid temperature occasion that has certain requirements, particularly be easy to the lower oils solution of chemical liquid, burning-point that burns, temperature-detecting device must be set in addition specially, increase investment, operation inconvenience.In addition, this instrument tongue tube position is and maintains static shape, thereby liquid level shows with controlling value also fixing thereupon.This makes troubles to the use occasion that liquid level requires to adjust.Sometimes, even can't finish necessary working.
At above-mentioned deficiency, the utility model provides a kind of temperature alarming liquid level to pick up the survey device.Except that show detecting the liquid level height, continuous detecting fluid temperature automatically still is for flammable liquid provides safety assurance, for technological requirement provides operating basis.In addition, the liquid level height is easy to adjust, more can adapt to production requirement, improves working conditions, and reduces labor intensity.
In order to realize above-mentioned target, the utlity model has following key technical points: thermal sensor element is placed below the liquid level, temperature value is done remote the transmission by circuit.Tongue tube on the axle by non magnetic removable clamper location, makes things convenient for the right position to regulate.
Modern thermal sensing element is very reliable, has obtained common employing.Long distance transmits Temperature numerical and also belongs to easy thing.Tongue tube is located with removable the connection with axle, and the possibility and very convenient that becomes is moved in the position, and regular liquid level adjustment and control just can fully be satisfied technological requirement.
Below in conjunction with accompanying drawing, further describe the utility model.
Fig. 1 is a temperature alarming liquid level detector structural representation.
Ball float (2) can be done axially-movable along conduit (1) with liquid surface lifting.Magnet steel in the ball float (2) just shows the magnetic induction effect to the tongue tube (4) of minimum distance, thereby causes tongue tube (4) action, starts external circuits.Magnet steel (3) is during away from tongue tube (4), and tongue tube (4) restores to the original state automatically, the external circuits automatic cutout.In view of the above, the liquid level height can be detected and be transmitted by the tongue tube position.
For continuous, automatic tracer liquid temperature, install heat conducting cover plate (8) in conduit (1) bottom, in order to sealing duct (1) bottom, heat transfer good conductors such as its material available copper, aluminium, devitrified glass are in the hope of flash heat transfer.
At least be provided with a thermal sensor element (7) in the conduit (1), in order to the tracer liquid temperature.Usually thermal sensing element (7) (as thermopair, temperature relay etc.) can be placed on the heat conducting cover plate (8), to obtain the temperature of liquid bottom.For tracer liquid upper strata temperature, also can a plurality of thermal sensor elements (7) be set, as a, b place in conduit (1) internal upper part zone.
The heat that heat sensitive sensor element (7) receives will reach control desk with the electric signal form, show as Temperature numerical.Its value surpasses specified limits, will cause alerting signal.
In order to regulate the liquid level height arbitrarily, on axle (5), be provided with non magnetic removable positioning clamp holder (10), in order to clamping tongue tube (4).Clamper (10) divides elastic opening collar (6), the clamp of remaining silent various ways such as (9).
Elastic opening collar (6) is like machinery elastic scheibe commonly used, make versus buy all can, but material is non-magnetic material, as copper, aluminium, plastics etc.The clamp of remaining silent (9) available " O " RunddichtringO, little shape " hula hoop " etc.Nonmagnetic clamper (10) does not influence the magnetic induction effect of magnet steel (3) to tongue tube (4), prevents to produce misoperation.
Claims (3)
1, a kind of temperature alarming liquid level detector mainly contains thermal sensor element (7), clamper (10), heat conducting cover plate (8), conduit (1), elastic opening collar (6) and the clamp of remaining silent (9), it is characterized in that:
(1), have a thermal sensor element (7) at least in the conduit (1),
(2), has a clamper (10) at least on the axle (5).
2, temperature alarming liquid level detector according to claim 1 is characterized in that: the flexible expanding ring of clamper (10) (6), the clamp of remaining silent various ways such as (9), and material is nonmagnetic.
3, temperature alarming liquid level detector according to claim 1 is characterized in that: install heat conducting cover plate (8) in conduit (1) bottom, its material is the heat transfer good conductor.
