Description
Technical field
The present invention relates to control instrument, especially level control instrument.
Background technology
Water tower is the major equipment supplied water to vast small towns, urban residents, and general using method is: the water in the water tank of water tower is finished, and after the not water outlet of water pipe stream, employment pump motor of fetching boiling water is fetched water in the water tank of water tower.See or hear that the water spill-over in the water tank of water tower goes out, then the motor that switches off the pump stops supplying water.This method will someone operate.The water that water spill-over goes out slatterns.
Summary of the invention
The object of this invention is to provide a kind of level control instrument, can in waterborne in the water tank of water tower be raised to and need position, make electric water pump stop supplying water.In the water tank of water tower drop to bottom under water time, water pump just can water supply start.
The object of the invention is to realize as follows: utilize the performance that water can conduct electricity, waterborne in the water tank of water tower connects the coil of contactor when being raised to and needing position, make the normally closed interlock power-off of contactor, pump motor stops.In the water tank of water tower, drop to bottom under water, disconnect the coil of contactor, the normally closed interlock of contactor be energized, pump motor opens the cistern water supply of beginning to water tower.
Water inlet controls bottom electrode and water inlet controls the bottom that top electrode is contained in the water tank of water tower, cut off the water and control bottom electrode and cut off the water to control the liquid level place that top electrode is contained in the water tank needs of water tower, water inlet controls bottom electrode and is connected with contactor coil one end, the other end of contactor coil is connected with one end of transformer output winding, the other end of transformer output winding controls top electrode and is connected with cutting off the water, control bottom electrode of cutting off the water controls top electrode with water inlet and is connected, contactor normally open contact connects cut off the water control bottom electrode and control top electrode of cutting off the water, the two ends of transformer input coil are connected on power line respectively, power line is introduced by fuse, pump motor is connected with power line by the normally closed interlock of contactor, water inlet controls bottom electrode, water inlet controls top electrode, control bottom electrode of cutting off the water is welded with a small amount of argent with the end points controlling top electrode of cutting off the water.
The advantage of this level control instrument is: water tower can be made to have water all the time, and the process implementation that adds water controls automatically, saves manpower, water-saving and environmental protection, and level control instrument structure is simple, dependable performance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing is the schematic diagram of water tower liquid surface controller.
1. pump motors, 2. contactor coil in figure, 3. contactor normally closed interlock, 4. water tower, 5. transformer, 6. water inlet controls bottom electrode, and 7. water inlet controls top electrode, 8. fuse, 9. power line, control bottom electrode of 10. cutting off the water, 11. cut off the water control top electrode, 12. contactor normally open contacts.
Embodiment
In the accompanying drawings, electrode adopts the sub-thread copper core of the exhausted rubber of normal tape, and weld a small amount of argent at copper core end points, its effect conducts electricity very well, anticorrosive.The serviceable life of level control instrument can be increased.The installation of electrode is generally the hole of boring a minor diameter in the corresponding installation position of the water tank of water tower, seals after putting into electrode with water tight packing.Water inlet controls bottom electrode (6) and water inlet controls 50 ~ 100 millimeters, the bottom place that top electrode (7) is contained in the water tank of water tower (4), and water inlet controls bottom electrode (6) and water inlet controls 20 ~ 30 millimeters, top electrode (7) interval.Cut off the water and control bottom electrode (10) and cut off the water to control the liquid level place that top electrode (11) is contained in the water tank needs of water tower (4), generally 200 ~ 400 millimeters of places below the water tank of distance water tower (4) is suitable for reading.Cut off the water and control bottom electrode (10) and cut off the water to control 20 ~ 30 millimeters, top electrode (11) interval.In order to safety, adopt low-voltage contactor, need to be depressured to 24 volt to electricity through transformer (5) introduce from power line (9) two, supply operation circuit.Water inlet controls bottom electrode (6) and is connected with contactor coil (2) one end, the other end of contactor coil (2) is connected with one end of transformer (5) output winding, the other end of transformer (5) output winding controls top electrode (11) and is connected with cutting off the water, control bottom electrode (10) of cutting off the water controls top electrode (7) with water inlet and is connected, contactor normally open contact (12) connects cut off the water control bottom electrode (10) and control top electrode (11) of cutting off the water, the two ends of transformer (5) input coil are connected on the corresponding line of power line (9) respectively, power line (9) is introduced by fuse (8), pump motor (1) is connected with power line by the normally closed interlock (3) of contactor.When liquid level be increased beyond cut off the water control top electrode (11) time, cut off the water control bottom electrode (10) and cut off the water control top electrode (11) connection contactor coil (2).Contactor normally open contact (12) adhesive, the normally closed interlock (3) of contactor is separated power-off, and pump motor (1) stops, and supplies water and terminates.When the water of the water tank of water tower (4) is used up, liquid level controls top electrode (7) below in water inlet, water inlet controls bottom electrode (6) and water inlet controls top electrode (7) disconnection, contactor is separated, the normally closed interlock (3) of contactor is connected, pump motor (1) water supply start.
