The invention has the beneficial effects as follows: the present invention adopts and utilizes PH controller detection potential of hydrogen to control pre-treatment tank water valve Push And Release, solved the present situation that the nothing of closing water artificially in present pre-treatment tank scene quantizes a large amount of tap water of management waste, simple, safe and reliable, can be widely used in the water valve control of the pre-treatment tank of various process of surface treatment, very big economical effectiveness is not only arranged, also have great water-saving and environmental protection meaning and social benefit.
Description of drawings
Fig. 1 is the schematic circuit diagram of the specific embodiment of the invention one;
Fig. 2 is the schematic circuit diagram of the specific embodiment of the invention two.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figure 1, water valve of surface treatment rinsing bath automatic control device employing model is two probe PH controllers of OPM223 among the embodiment one, two probes are positioned over oil removing after washing groove, the interior appropriate location of phosphatization after washing groove respectively, probe is connected with the PH controller will be detecting the pH value of washing bath, and the PH controller is connected with automatically controlled valve switch to export control signal when recording pH value and reach set(ting)value controls valve switch.
Automatically controlled valve switch comprises that intermediate relay KA1, KA2 and line bag are water valve YV1, the YV2 of direct current 24V voltage, the external 220V of water valve exchanges and reaches direct current 24V through overcommutation, to guarantee being safety voltage from the circuit that controlling box comes out, utilize the inner contact 48,49 or 58,59 of PH controller to control intermediate relay KA1, KA2 line bag power supply, and the power supply of valve switch is by the normally opened contact control of intermediate relay KA1, KA2.
When the pH value of oil removing after washing groove greater than 9.2 the time, the PH controller is given inner contact 48,49 electrical signal, intermediate relay KA1 line is surrounded by electricity, 2,3 closings of contact of KA1, the water valve YV1 that oil removing after washing groove supplies water gets electric, is in opened condition, feed trough supplies water; When the pH value of oil removing after washing groove less than 8.5 the time, the PH controller is given inner contact 48,49 power-off signals, the outage of intermediate relay KA1 line bag, 2,3 contacts of KA1 disconnect, water valve YV1 outage stops feed trough and supplies water.And for phosphatization after washing groove, when the pH value of phosphatization after washing groove less than 4.8 the time, the PH controller is given inner contact 58,59 power on signal, intermediate relay KA2 line Bao Dedian, 2,3 closings of contact of KA2, the water valve YV2 electric section of giving the water supply of phosphatization after washing groove is in opened condition, and feed trough supplies water; When the pH value of phosphatization after washing groove greater than 5.7 the time, the PH controller is given inner contact 58,59 power-off signals, the outage of intermediate relay KA2 line bag, 2,3 contacts of KA2 disconnect, water valve YV2 outage stops feed trough and supplies water.
When probe needs maintenance or controller to overhaul, button transfer lever QF is transformed into micro computer time controller (model is KG316T) position, the unlatching of each water valve no longer is subjected to the control of PH controller, but has given the micro computer time controller that has two normally opened contacts in parallel with intermediate relay 2 normally opened contacts.In setting water supply time, the closing of contact of micro computer time controller, water valve gets electric, and water valve is opened, and feed trough supplies water; In setting stopped water supply time, the contact of micro computer time controller disconnected, and the water valve outage stops feed trough and supplies water.
The water valve of surface treatment rinsing bath automatic control device adopts and has single probe PH controller that 1 probe, model are ORP2002 in embodiment illustrated in fig. 2 two, promptly adopt 2 controllers to control the valve switch of two washing baths respectively, but principle is identical with embodiment's one, does not therefore state tired.
After adopting the Push And Release of such scheme control pre-treatment tank tap water, pre-treatment tap water consumption can decline to a great extent, and on the statistics of the wastewater treatment tonnage of every day, when using PH controller control pre-treatment tap water, can save the tap water more than 40%.
