The air pipe is respectively connected with the air regulator and the differential pressure transmitter. The air regulator compresses air. The liquidometer is capable of accurately displaying a liquid level under hostile environment.
Description
Technical field
The utility model belongs to field of instrumentation technology, is specifically related to a kind of liquid level gauge.
Background technology
The scale pit well structure is special, two adjacent circles, the underground hole of the reinforced concrete that build is larger body, now use ultrasonic level gage or radar level gauge, but because on-the-spot water quality inferiority, environment is abominable, coolant-temperature gage is high, greasy dirt is serious etc. in the large and water of fog, make radar, ultrasonic level gage is subject to the impact in various degree of greasy dirt and water vapor in the water, cause to react accurately current real-time level, can't eliminate liquid level hidden danger, thereby can't automatic controlled underground scale pit well outlet valve and reverse flow valve switch, and repeatedly cause liquid level gauge numerical value constant, cause underground iron sheet effluent well outlet valve and reverse flow valve switch unusual, thus the dangerous industrial accident such as cause that underground iron sheet effluent well waterflooding and water pump sky are taken out.
The utility model content
The purpose of this utility model provides a kind of device that badly can accurately show liquid level at environment.
The technical scheme that the utility model adopts is:
A kind of liquid level gauge comprises liquid-level probe, source of the gas voltage stabilizer and differential pressure variator, and described liquid-level probe is connected with tracheae, and described tracheae is connected with the differential pressure variator with the source of the gas voltage stabilizer, described source of the gas voltage stabilizer pressurized air.
Further, described tracheae is crossed the first three-way connection and is connected with the differential pressure variator with the source of the gas voltage stabilizer.
Further, described liquid-level probe links to each other with the second three-way connection, described the second three-way connection with proofread and correct stop valve and be connected tracheae and be connected.
Further, described source of the gas voltage stabilizer links to each other with stop valve.
Further, the signal output part of described differential pressure variator links to each other with the PCL signal input part.
Preferably, described liquid-level probe is galvanized conduit or plastic tube.
The utlity model has following having a few:
This apparatus structure is simple, production cost is low, environment is abominable at the scene to utilize this device, water quality inferiority, coolant-temperature gage is high, fog is large and water in the data that demonstrate accurately the liquid level in the scale pit well in the environment of greasy dirt, so just eliminated liquid level hidden danger, thereby can automatic controlled underground scale pit well outlet valve and reverse flow valve switch, cause liquid level gauge numerical value to change, make underground iron sheet effluent well outlet valve and reverse flow valve switch normal, thus the dangerous industrial accident such as prevented that effectively underground iron sheet effluent well waterflooding and water pump sky from taking out.This device can also be monitored the more liquid level field of underwater bubble simultaneously.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is described in further detail.
Fig. 1 implements the structural representation of a kind of liquid level gauge that 1 example provides for the utility model.
Embodiment
With reference to Fig. 1, a kind of liquid level gauge comprises liquid-level probe 3, source of the gas voltage stabilizer 7 and differential pressure variator 10, and liquid-level probe 3 is galvanized conduit.Liquid-level probe 3 is connected with stop valve by the second three-way connection 5 and tracheae 6 and is connected.Tracheae is connected 10 with source of the gas voltage stabilizer 7 with the differential pressure variator by the first three-way connection 11, and source of the gas voltage stabilizer 7 links to each other with stop valve 8.Source of the gas voltage stabilizer 7 logical pressurized air 9.The signal output part of differential pressure variator 10 links to each other with the PCL signal input part.
The principle of work of this device is: do liquid-level probe 3 with 4 minutes galvanized conduit, enter the oil-containing high temperature sewage 2 of scale pit well 1 from a monitoring mouthful straight cutting.Pressurized air 9 about external 0.4MPa through the stop valve 8 of maintenance usefulness, arrives liquid-level probe 3 with stable 0.22MPa pressurized air by tracheae 6, correction stop valve 4 by source of the gas voltage stabilizer 7, does not stop to advertise stable pressurized air to oil-containing high temperature sewage 2.Be connected on the differential pressure transmitter 10 with the first three-way connection 11 and tracheae 6 simultaneously, because the water level of oil-containing high temperature sewage 2 is changing, therefore the hydraulic pressure at liquid-level probe 3 places and air pressure form also constantly variation of pressure reduction, by source of the gas voltage stabilizer 7 variation in water pressure of stable 0.22MPa constant compression air pressure and measured medium is passed into differential pressure transmitter 10 by the pressurized air about external 0.4MPa, act on the both sides diaphragm of differential pressure transmitter 10 sensitive elements, be sent to the measuring diaphragm both sides by the filling liquid in diaphragm and the element, the electrode of measuring diaphragm on the insulating trip of both sides respectively forms a capacitor, when pressure at both sides is inconsistent, cause measuring diaphragm to produce displacement, its displacement and pressure differential are directly proportional, therefore the both sides electric capacity does not just wait, by vibration and demodulation link, convert the signal that is directly proportional with pressure to, convert the curent change value of detuner to digital signal by A/D converter again, be presented on the PLC by the signal conversion again, monitoring current scale pit well 1 real-time level shows, control iron sheet outlet valve and reverse flow valve switch are realized Real Time Monitoring and robotization control.
Apparatus structure is simple, production cost is low, environment is abominable at the scene to utilize this device, water quality inferiority, coolant-temperature gage is high, fog is large and water in the data that demonstrate accurately the liquid level in the scale pit well in the environment of greasy dirt, so just eliminated liquid level hidden danger, thereby can automatic controlled underground scale pit well outlet valve and reverse flow valve switch, cause liquid level gauge numerical value to change, make underground iron sheet effluent well outlet valve and reverse flow valve switch normal, thus the dangerous industrial accident such as prevented that effectively underground iron sheet effluent well waterflooding and water pump sky from taking out.This device can also be monitored the more liquid level field of underwater bubble simultaneously.
The present embodiment as different from Example 1, when the solution of scale pit well 1 was Acidity of Aikalinity, liquid-level probe 3 was plastic tube, so just can prevent that liquid-level probe 3 is corroded.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
