When the utility model is used on a boiler, the combined device has the functions of an automatic measuring device and a water level direct reading liquid level gage, and the old volumetric cylinder structure of the water level sensor is eliminated. The utility model has the advantages of simple structure and low cost, which is suitable for various liquid storing tanks.
Description
The utility model belongs to the surveying instrument class, and it is a kind of capacitance level gauge that is used for the level gauging that the storage of liquid such as boiler irritates.
Present domestic steam boiler level measuring mostly adopts the mode of two covering device concurrent workings, first boiler water level self-operated measuring unit, and it two is direct-reading liquid level gauges.The effect of boiler water level self-operated measuring unit is to utilize level sensor to obtain water level signal, delivers to secondary instrument then water level is measured automatically.The effect of direct-reading liquid level gauge is to allow the stoker personnel intuitively read boiler water level by liquid level gauge.Two covering devices are independent mutually.The level sensor of existing in addition boiler water level self-operated measuring unit mostly adopts the volumetric cylinder structure, promptly at the various forms of level sensors of the inner installation of the volumetric cylinder of a special use.And the parallel volumetric cylinder outside that is installed in of direct-reading liquid level gauge.With the patent No. be: 86210228.6, name is called: " GDK-1 type boiler water level electronic monitor " is example: this water level electronic monitor needs a special volumetric cylinder, the sensor installation made.A special-purpose blowoff valve also will be installed under the volumetric cylinder.Its shortcoming is: structure relative complex, cost height, and behind the parallel installation of volumetric cylinder one side direct-reading liquid level gauge, volume and weight is all bigger, and it is more to take up room.In addition, the gas-water channel between boiler air water connecting leg flange and liquid level gauge flange must be through the volumetric cylinder three-way pipeline at two ends up and down, gas-water channel is stopped up owing to dirt and incrustation scale at volumetric cylinder three-way pipeline place, thereby reduced the reliability of level measuring relatively.
At the problems referred to above, the purpose of this utility model provides a kind of capacitance level gauge, the function of one covering device is equivalent to the function that existing automatic water level measurement device and water level direct-reading liquid level gauge two covering devices are risen, and has abolished the old-fashioned volumetric cylinder structure of level sensor.
The utility model is made up of single channel double colored indicator, condenser type level sensor etc.It is characterized in that: (1) parallelly is equipped with a long garden cylindricality metal electrode in the gas-water channel of double colored indicator left side metal table body one side; (2) the metal table body of this metal electrode and double colored indicator is respectively as two utmost points of capacitance type sensor.(3) growing the insulation course that passes through long garden cylindricality metal electrode outside surface between garden cylindricality metal electrode and metal table body and measured medium isolates.
Principle of work of the present utility model is: the electric capacity of condenser type level sensor changes along with the change of the specific inductive capacity of measured medium (the stove water in the gas-water channel), handles thereby will be sent to intelligence instrument by the SEA LEVEL VARIATION signal that the condenser type level sensor obtains.
The utility model one-piece construction is simple, cost is low, it is little to take up room, and measurement effect is stable accurately and reliably.Can realize multiple functions such as boiler water position automatic measuring and demonstration directly perceived, and the condenser type level sensor can carry out continuous coverage to stove water, not have the dead band; Can be under the environment of 200 ℃ of high temperature and stove water erosion reliably and with long-term work.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of single channel double colored indicator.
Fig. 3 is the structural representation of condenser type level sensor.
Specify embodiment of the present utility model below in conjunction with accompanying drawing:
As Fig. 1 and shown in Figure 3: part (1) is the left-handed watch body of double colored indicator.Part (2) is the lead of long garden cylindricality metal electrode.Part (3) is a fluid sealant.Part (4) is long garden cylindricality metal electrode.(5) be the interior gas-water channel of double colored indicator.Part (6) is a double colored indicator.(7) be insulation course.(8) be support.
With the utility model integral installation on boiler.See Fig. 2 and Fig. 3: long garden cylindricality metal electrode (4) (utmost point of capacitance type sensor) and insulation course (7) thereof are installed in parallel in the gas-water channel (5) of double colored indicator left side metal table body (1) (another utmost point of capacitance type sensor a) side by support (8).Separate by insulation course between long garden cylindricality metal electrode (4) and left-handed watch body (1) and the measured medium.The length of long garden post metal electrode equals the length of gas-water channel (5) in the left-handed watch body, and promptly electric capacity is full of whole table body inside, so can carry out continuous coverage to stove water, does not have the dead band.The lead of long garden post metal electrode is drawn by an aperture of left-handed watch body (1).This fairlead seals with high-temperature seal adhesive (3).This lead and intelligence instrument join.
When boiler water level changed, the stove water (measured medium) in the gas-water channel (5) of double colored indicator (6) is invaded did not have the degree of depth of capacitance type sensor electrode to change yet.Because the specific inductive capacity of sensor electrical interpolar measured medium changes, and the electric capacity of sensor is also changed.The SEA LEVEL VARIATION signal that obtains from sensor is sent to intelligence instrument by lead (2) and handles.Intelligence instrument is controlled by microcomputer.The stoker personnel also can obtain water level signal from the virtual display unit of single channel double colored indicator (6) simultaneously.
The insulation course (7) of long garden post metal electrode of the present utility model (4) adopts a kind of electrical property and chemical stability is all good and resistant to elevated temperatures insulating material is made; Sometimes for reducing cost, insulation course will adopt some cheap materials, the electric heating property of this material (as plastics, nylon) is relatively poor, therefore when measuring, can dielectric distribution be changed because of the variation (making insulating material expansion etc.) of temperature and pressure, therefore bring error to measurement, in order to eliminate this influence, the two-section that the long garden cylindricality metal electrode (4) of capacitive transducer can be designed to equate, when measuring, can take out these two signals simultaneously and carry out data processing, to eliminate the influence that temperature, pressure produce measuring accuracy.It is water-tight gentle that the fairlead of contact conductor (2) can guarantee under the 1.6MPa steam pressure.
The utility model adapts to various liquid storages and irritates.
