The utility model embodiment provides a kind of liquid level emasuring device, shown in Fig. 1 (a), Fig. 1 (b) and Fig. 1 (c), comprises housing 11, also comprises: flexible member 12, gear train 13, pointer 14 and index dial 15, wherein,
One end of flexible member 12 is the stiff end of opening, is communicated with testing liquid; The other end links to each other with gear train 13 for the free end of sealing;
Said gear train 13 links to each other with pointer 14, and when said free end is subjected to displacement because of hydraulic action, drives needle deflection; Concrete, when the free end of flexible member 12 was subjected to displacement under the hydraulic action of inflow flexible member 12 internal liquids, said gear train 13 was with said free end motion and drive pointer 14 deflections;
Said index dial 15 is provided with the scale of representing testing liquid liquid level height according to pointer 14 degree of deflection.
Preferable, better contacting in order to make flexible member 12 with testing liquid, said liquid level emasuring device also comprises: erection joint 16 links to each other with the stiff end of said flexible member 12, and is communicated with testing liquid.
Preferable, said flexible member 12 is a bourdon tube, and said bourdon tube can be in ring-like pipe, C type pipe, spiral pipe and the coil pipe any one.Perhaps, this flexible member 12 can also be other sensitive elements, as long as can deformation take place according to hydraulic pressure, thereby measurement hydraulic pressure and liquid level get final product.
Preferable, said gear train 13 comprises: connecting rod 131, one ends link to each other with said free end, and the other end links to each other with adjuster bar 132; Adjuster bar 132, one ends link to each other with said connecting rod 131, and the other end links to each other with gear; The gear (not shown) is with the central shaft engagement of said pointer 14.Perhaps, this gear train 13 can also adopt other implementation, for example, adopts one or more gears to carry out transmission, perhaps, realizes through a plurality of interconnective adjuster bars.In a word, as long as can realize that 12 free-ended motions drive the effect that pointer 14 deflects according to flexible member.
Preferable, can be designed to index dial 15 fan-shaped.For example, this fan-shaped arc angle can be 240 degree.Adopt such shaped design, convenient when traditional circular scale reads.And, can also be accordingly also be designed to housing 11 tops of this liquid level emasuring device fan-shaped, not only attractive in appearance but also can safely place.
Here, the scale of expression testing liquid liquid level height can calculate according to fluid density and hydraulic pressure in advance on the index dial 15.And, can also kind of liquid be arranged in the corresponding sign in the next door of the scale on the said index dial.Preferably, in order to widen the range of application of this liquid level emasuring device, can on said index dial, identify has the various liquid type, and identifies the scale that is used for express liquid liquid level height to every kind of kind of liquid respectively.
Through adopting the liquid level emasuring device in the utility model, utilize flexible member induction hydraulic pressure, and, design the scale of expression liquid level height, thereby confirm liquid level through measuring hydraulic pressure according to the relation between hydraulic pressure and the liquid level.This liquid level emasuring device has that cost is low, volume is little, simple in structure, and convenient for installation and maintenance, be prone to sweep and advantage such as check.
Describe the liquid level emasuring device in the utility model in detail with a preferred embodiment below, in the present embodiment, flexible member 12 adopts the annular elastomeric reed pipes to realize.And the liquid level emasuring device in the present embodiment is installed in the container bottom that needs measuring liquid level, shown in Fig. 2 (a) and Fig. 2 (b).Fill liquid in container 20 inside, be provided with an opening in the bottom of container 20, promptly adopt a mouth 21, therefore, the liquid in the container 20 can flow in the bourdon tube of liquid level emasuring device 22 inside through the erection joint of adopting on a mouth 21 and the liquid level emasuring device 22.Thereby make bourdon tube generation deformation and then measure hydraulic pressure.The liquid level of measured liquid is high more, and the suffered pressure of bourdon tube is also big more, forces the degree of annular elastomeric reed pipe bending also big more, and therefore, bourdon tube drives gear train, and pointer is rotated, thereby reaches the effect that liquid level shows.And, for the ease of this liquid level emasuring device is carried out Maintenance and Repair, but the valve 23 of a break-make can also be set between the erection joint of adopting a mouth 21 and liquid level emasuring device of container 20; Like this, when needs were measured and show liquid level, this valve 23 was a normally open; And when liquid level emasuring device breaks down the needs maintenance; Then valve 23 is closed, stop the liquid in the container 20 to get into, thereby liquid level emasuring device is overhauled.Preferable, can also this valve be arranged on the inside of erection joint, and, can the switch of this valve break-make of control be arranged on this liquid level emasuring device, like this, it is more convenient to use.
And, for to the accurate measuring liquid level of different liquid, need calculated in advance to go out liquid level scope and mark; Such as; If the liquid level scope in the container is 0 to 5 meter a water level, then the bourdon tube pressure should be 0 to 50KPa accordingly, with 0 on the index dial to 5 meters corresponding.
In addition, because different liquid has different density, therefore, under same hydraulic pressure; Corresponding liquid level is different because of fluid density, like this, except that showing the liquid level scope, also should identify the corresponding liquid type to the liquid level scope simultaneously on the index dial; For example, the concentrated sulphuric acid to 90%, density is 1.80 grams per milliliters; When the highest liquid level was 5 meters, then bourdon tube pressure size should be between 0 to 90KPa, with 0 on the index dial to 5 meters corresponding.This liquid level emasuring device can also calculated in advance goes out hydraulic pressure and the mutual relationship between the liquid level of the liquid of multiple different densities, produces the liquid level scale to every kind of kind of liquid respectively then, thereby user-friendly.
When concrete the realization, can also select to have the bourdon tube material of different flexural properties according to the different densities of liquid and the differing heights of liquid, to reach accurate demonstration.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
