Please refer to shown in Figure 1ly, the utility model computer liquid level control device 100 comprises automatic control case 1, motorized valve 2, water inlet pipe 3 and liquid-level probe 5.Be provided with controller (not shown), automatic electronic computer (not shown) and signal processing apparatus (not shown) in the above-mentioned automatic control case 1, and above-mentioned controller, automatic electronic computer and signal processing apparatus can be set to one, automatic control case 1 can be accomplished unattended, safe and reliable to operation like this.
Motorized valve 2 is arranged on the water inlet pipe 3, the aperture control of this motorized valve 2 is just carried out level Four or the adjustment of eight grades of aperture self-adaptations by water level, in embodiment of the present utility model, motorized valve 2 adopts level Four aperture self-adaptation to adjust, when motorized valve 2 standard-sized sheets, water inlet pipe 3 is with flow moisturizing in water tank 8 of maximum, and when motorized valve 2 complete shut-downs, water inlet pipe 3 is moisturizing in water tank 8 not.Preferably, motorized valve 2 can be one of them of electric gate valve, electric control valve, pneumatic control valve, electric butterfly valve.The control line 21 of motorized valve 2 is continuous with the corresponding wiring in the automatic control case 1.
Liquid-level probe 5 is a three-wire system line position probe, and the signal wire 51 of liquid-level probe 5 links to each other with transmission liquid level control 5 water level signal that record with the 1 interior corresponding wiring of automatic control case.Signal wire 51 is shielded fully.Liquid-level probe 5 is positioned over the position of water tank 8 near the bottom, because liquid-level probe 5 is made by stainless steel, only be responsible in water, measuring water level and just and with the signal of measuring be transferred in the signal processing apparatus of automatic control case 1, come control water level, prevent that water level is too high or low excessively with this.Liquid-level probe 5 is fixed in position, and signal wire 51 can be fixed on the water tank top, also can be fixed to other positions.
Above-mentioned automatic control case 1 can also be preset liquid level display window (not shown) and computer interface (not shown), the liquid level display window can be intuitively to the height of observing liquid level, and the computer interface position can insert a control computer, thereby realizes artificial control.Automatic control case 1 can also be provided with warning device (not shown), described warning device or to be one of audible alarm unit, light warning device, acoustic-optic alarm.Preferably, described automatic control case 1 is a cuboid, is of a size of 800mm*600mm*250mm.
Please be simultaneously with reference to shown in Figure 2; the utility model comprises a plurality of pilot lamp; described pilot lamp comprises the power light Hw whether the indication power supply is connected; the indication valve is in pass valve pilot lamp 1HG just in off position; the indication valve just is in opens valve pilot lamp 2HG in opening; the indication valve closing; stop the complete shut-down pilot lamp 1HR of moisturizing state; the indication valve wide open; the standard-sized sheet pilot lamp 2HR of water inlet pipe current maximum rating; and protection pilot lamp; FU is a fuse; the computer liquid level control device is carried out overcurrent protection; when FU fused, the protection pilot lamp is luminous notified the user.Branch road M and branch road N close valve control and open valve control motorized valve 2 respectively.Computer control SSR, PID are the signal of surveying according to liquid-level probe 5 and handle and control opening, opening of motorized valve under automatic control state.During make contact A, the motor circuit in left side enters work and water level in the water tank 8 is manually controlled; When make contact B, C, the right side circuit enters work and controls and field control carrying out automatic electronic computer in the water tank respectively.
Please be simultaneously with reference to shown in Figure 3, computer liquid level control device 100 of the present utility model when work, energized, this moment, power light Hw was luminous, the water levels in 5 pairs of water tanks of liquid-level probe 8 are monitored.Automatic electronic computer shown in Figure 3, controlled adjuster and signal processing apparatus all are to be placed in the automatic control case 1, mid water levels point in the above-mentioned water tank 8 can be set arbitrarily as required, and the present embodiment middle water level is divided four limiting water levels: superelevation water level 801, high water stage 802, low-water level 803 and ultralow water level 804.
When the utility model computer liquid level control device 100 is controlled automatically, water level in 5 pairs of water tanks of liquid-level probe 8 is monitored in real time, with monitor data send in the automatic control case 1 automatic electronic computer and controlled adjuster to and handle, signal after the processing is sent to signal processing apparatus, by signal processing apparatus according to the water system rate of water make-up, water level, automatically regulate opening of motorized valve 2, degree of opening or close, and then open or close water inlet pipe 3, make stable level in the water level range of setting, thereby when guaranteeing moisturizing, the automatic-closing valve when water levels in the water tank 8 reach the high water stage of setting, behind valve closing, if when the water level in the water tank 8 reached low-water level, then water compensating valve was opened moisturizing automatically.
For example, if recording water level, liquid-level probe 5 is in ultralow water level 804, warning device is opened warning function, 1 pair of motorized valve 2 of automatic control case is controlled, this moment, motorized valve was in the standard-sized sheet aperture, water inlet pipe 3 carries out moisturizing with maximum flow of inlet water to water tank 8, when liquid-level probe 5 records water level and is between ultralow water level 804 and the low-water level 803, then the aperture of automatic control case 1 control motorized valve 2 reduces, and rate of water make-up reduces, when liquid-level probe 5 records the water outlet of water tank and water inlet when reaching balance, need the certain water level in the maintenance water tank, then motorized valve is failure to actuate, and water-level fluctuation reaches minimum in the water tank thereby make, and water reaches best water supply state in the water tank; When water level is in high water stage 802 in the water tank 8 that records, automatic control case 1 control motorized valve 2 complete shut-downs, water inlet pipe 3 stops into water.If liquid-level probe 5 records when water level is in superelevation water level 801 in the water tank 8, automatic control case 1 impels warning device to report to the police, and water level carries out field control in motorized valve 2 or the water tank 8 so that the staff manually assists to close.
When the utility model is carried out manual moisturizing, according to liquid-level probe 5 detected signals, the liquid level display window of automatic control case 1 just shows the liquid level in the water tank, according to the data of liquid level display window to valve switch control manually control, moisturizing is carried out in the control of Open valve switch when low-water level, valve-off switch control stopping moisturizing when high water stage.
When carrying out moisturizing control at the scene, then motorized valve 2 is left valve control or closes valve control according to the liquid level height of field observation, do not give unnecessary details at this.
Preferably, the motorized valve input signal of the utility model computer liquid level control device 100 is: ultrasound wave (throw-in type) liquid-level probe: range 10m, 0～10mA (need join 500 Ω sampling resistors), motorized valve 2 apertures: resistor-type 350 Ω-1k Ω.Output signal is motorized valve 2 open and close signals, high water stage, low-water level shows signal, superelevation water level, ultralow water-level alarm signal.The switching value of the open and close of motorized valve 2 or current signal system, liquid level shows provides passive contact or special purpose interface.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
