Description
Technical field
The present invention relates to control instrument, especially level control instrument.
Background technology
Water tower is the major equipment that supplies water to vast small towns, urban residents, and general method of application is: the water in the water tank of water tower uses up, and after water pipe flowed not water outlet, the personnel selection pump motor of fetching boiling water was 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 that the motor that switches off the pump again stops to supply water.This method will someone be operated.The water that the water spill-over goes out slatterns.
Summary of the invention
The purpose of this invention is to provide a kind of level control instrument, can be in the water tank of water tower waterborne be raised to need the position in, make electric water pump stop to supply water.When dropping to bottom time under water in the water tank of water tower, water pump just can water supply start.
The objective of the invention is to realize as follows: connect the coil of contactor when the performance of utilizing water to conduct electricity, waterborne in the water tank of water tower are raised to and need the position, make the normally closed interlock outage of contactor, pump motor stops.In the water tank of water tower, drop to the bottom under water, break off the coil of contactor, make the normally closed interlock energising of contactor, pump motor begins the cistern water supply to water tower.
Water inlet control bottom electrode is controlled the bottom that top electrode is contained in the water tank of water tower with water inlet; The control bottom electrode of cutting off the water is controlled the liquid level place that top electrode is contained in the water tank needs of water tower with cutting off the water; Water inlet control bottom electrode is connected with contactor coil one end; The other end of contactor coil is connected with an end of transformer output winding; The other end of transformer output winding is connected with the control top electrode of cutting off the water, and the control bottom electrode of cutting off the water is connected with water inlet control top electrode, and normally open contact connection of contactor is cut off the water and controlled the bottom electrode and the control top electrode of cutting off the water; The two ends of transformer input coil are connected on the power line respectively; Power line is introduced through fuse, and pump motor is connected with power line through the normally closed interlock of contactor, and the end points of water inlet control bottom electrode, water inlet control top electrode, cut off the water the control bottom electrode and the control top electrode of cutting off the water is welded with a spot of argent.
The advantage of this level control instrument is: can make water tower that water is arranged all the time, add the water process and realize control automatically, practice thrift manpower, and water-saving and environmental protection, level control instrument is simple in structure, dependable performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Accompanying drawing is the synoptic diagram of water tower level control instrument.
1. pump motors among the figure, 2. contactor coil, 3. contactor normally closed interlock, 4. water tower; 5. transformer is 6. intake and is controlled bottom electrode, 7. water inlet control top electrode, 8. fuse; 9. power line, the control bottom electrode of 10. cutting off the water, the 11. control top electrodes of cutting off the water, 12. contactor normally open contacts.
Embodiment
In the accompanying drawings, the electrodes use normal tape cuts off the sub-thread copper core of rubber, welds a spot of argent at the copper core end points, and its effect is to conduct electricity very well, and is anticorrosive.Can increase the serviceable life of level control instrument.The installation of electrode generally is the hole of boring a minor diameter in the corresponding installation position of the water tank of water tower, seals with water tight packing behind the threading electrode.Water inlet control bottom electrode (6) and water inlet control top electrode (7) are contained in 50～100 millimeters places, bottom of the water tank of water tower (4), 20～30 millimeters at interval of water inlet control bottom electrode (6) and water inlet control top electrodes (7).Cut off the water control bottom electrode (10) and the control top electrode (11) of cutting off the water is contained in the liquid level place of the water tank needs of water tower (4), generally 200～400 millimeters places below suitable for reading apart from the water tank of water tower (4).Cut off the water control bottom electrode (10) with cut off the water control top electrode (11) interval 20～30 millimeters.For safety, adopt the low-voltage contactor, need be depressured to 24 volts passing through transformer (5) to electricity from two of power line (9) introducing, supply with operation circuit.Water inlet control bottom electrode (6) is connected with contactor coil (2) one ends; The other end of contactor coil (2) is connected with an end of transformer (5) output winding; The other end of transformer (5) output winding is connected with the control top electrode (11) of cutting off the water; The control bottom electrode (10) of cutting off the water is connected with water inlet control top electrode (7), and a normally open contact of contactor (12) connects cut off the water the control bottom electrode (10) and the control top electrode (11) of cutting off the water, and the two ends of transformer (5) input coil are connected on respectively on the corresponding line of power line (9); Power line (9) is introduced through fuse (8), and pump motor (1) is connected with power line through the normally closed interlock (3) of contactor.When liquid level rose above cut off the water control top electrode (11), cut off the water the control bottom electrode (10) and the control top electrode (11) of cutting off the water were connected contactor coil (2).Contactor normally open contact (12) adhesive, the normally closed interlock of contactor (3) separates outage, and pump motor (1) stops, and supplies water and finishes.When the water of the water tank of water tower (4) is used up, liquid level is below water inlet control top electrode (7), and water inlet control bottom electrode (6) breaks off with water inlet control top electrode (7), and contactor separates, the normally closed interlock of contactor (3) connection, pump motor (1) water supply start.
