In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
Technical scheme is stated to be described in detail.
As Figure 1-Figure 4, a kind of level gauge of steel band, including float 1, steel band 2, sprocket wheel 5, spring wheel 6 and wheeled steel 9,
Described float 1 is immersed in fluid to be measured, and one end is connected by link 20 and hook 19 with steel band 2, the centre position of steel band 2
Provided with least two identical tension disk rollers 4, the other end is wrapped in after sprocket wheel 5 to be connected with wheeled steel 9, and described sprocket wheel 5 is provided with
Trundle 8, trundle 8 is connected by fork 12 with the output shaft 11 of transmitter 10, described trundle 8 also with counter 3
In millimeter dial 16 be connected, the other end of the steel band 2 wound on described wheeled steel 9 is connected with spring wheel 6, spring
Wheel 6 is provided with balancing spring 7.
Wherein, in actual applications, described float 1 is hollow structure, is made of stainless steel, corrosion resistance
Good, sturdy and durable, installation site should be easily installed, debug, reading and maintenance, be preferably mounted on manhole, gauge hatch nearby or specially
The position that the hands such as the installing plate of door can be touched, while should be away from discharging opening or agitator, and flow distribution plate or anti-ripple cover are installed, with
Prevent liquid fluctuating from influenceing measurement accuracy and stability.
Wherein, in actual applications, described steel band 2 is provided with one section of water-gas delivery pipe or plating close to one end of float 1
The steel band conduit of zinc pipe material, the error of perpendicularity not should be greater than 5mm when steel band conduit is installed, and can be directly welded on tank skin, or
On catheter holder, after the installation site of float 1 is determined, you can determine each steel band conduit according to the full size of liquid level gauge
Length dimension, the inner surface of steel band conduit by cleaning treatment and will have the protective coating for preventing corrosion, and each joint is in connection
Polytetrafluoroethylraw raw material band auxiliary seal is used when connecing.
Wherein, in actual applications, ten meters of degrees wheels 13, rice degrees wheel 14, decimetre scales are included in described counter 3
Wheel 15 and millimeter dial 16, wherein the center position of millimeter dial 16 is connected by axle sleeve 18 with trundle 8, and is led to
Three adjusting screws 17 of triangle respectively are crossed into be fixed, not only can be by measurement accuracy using the counter 3 of special construction
Improve to millimeter rank, also make it that clear reading is accurate.
Wherein, in actual applications, in described counter 3 and bin residing for transmitter 10 full of corrosion-free property
Oil or other liquid, with sufficient lubrication or can prevent medium steam etch instrument.
Operation principle：The constant drawing that the float 1 being immersed in fluid to be measured is produced by gravity W, buoyancy F and by constant force device
Power T effect, when the vector of three power is equal to zero, float 1 is in quasi-equilibrium inactive state.Buoyancy during mechanical balance is
Constant, the volume V of float immersion liquid is steady state value.When liquid level changes, original mechanical balance is in float 1 by buoyancy
Under disturbance, new balance will be moved to by steel band.Liquid level detection device float drives steel band 2 to move according to the situation of liquid level
Dynamic, the trundle 8 that displacement transmission system identical tension disk roller 4 is instigated by the movement of steel band 2 on sprocket wheel 5 is rotated, and then is acted on
Counter 3 shows the situation of liquid level, and this level condition is converted into standard electric signal by transmitter 10, defeated by signal wire
Go out.
Adjust and use：It is attached after finishing, is turned when rotating clockwise 0~6 meter of 9 range of wheeled steel according to Fig. 1 structures
Turn to turn when 30 circle left and right, 0~18 meter of range when 20 circle left and right, 0~12 meter of range to turn 45 circles when 40 circle left and right, 0~20 meter of range
Left and right, then locks wheeled steel 9 with lock-screw, is allowed to rotate.At this moment balancing spring 7 is in running order, can be complete
Constant force is provided for float 1 in the range of journey, by the steel band 2 in gauge outfit one end, the tight of wheeled steel 9 is fixed on by sprocket wheel 5
Gu on screw, unclamping lock screw, turn that joystick is counterclockwise 3 weeks or so, while trip bolt is tightened, notes steel band 2
The phenomenons such as twist together, crimp can not occur, in order to avoid the movement of influence steel band 2；Handle is held, lock-screw is unloaded, slowly unclamps hand
Balancing spring 7 applies pulling force to steel band 2 and float 1 in handle makes very, tenses steel band 2；Liquid level change is simulated, detecting system operation is
It is no normal, after instrument is installed, it can be shown by user's actual requirement adjustment counter 3, the rotation positive handwheel 1/4 of gauge outfit is enclosed
Float 1 can somewhat be lifted, this reading of hour counter 3 should be changed, and illustrate that instrumentation is normal, you can come into operation.
For the instrument being correctly installed in works fine environment, in addition to the maintenance on daily surface, usually without special
Maintenance；, should be at periodically cleaning when there is pollutant to cover on float 1 or other piece surfaces in measured medium
Reason, breaks down to prevent instrumentation；The rotary part of instrument often should add a small amount of lubricating oil to be lubricated；In equipment rebuilding
When should pull down instrument and carry out cleaning treatment, and change the rubber seal of aging, with ensure instrument sealing and work can
By property.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
