Abstract
The utility model relates to a multi-purpose liquid-level automatic controller, composed of an upper box cover (1), a box body (2), an upper contact (7), a lower contact (8), a movable contact (11), a spring (4), a spring (3), a reed (5), a converting switch (6), a floater (12), a floater (13), etc. The utility model has the advantages of simple structure and reliable control and has the functions of water discharge and supply. The multi-purpose liquid-level automatic controller can be used for the drainage, the flood discharge, the reservoir filling, the water discharge, the water supply of domestic water pools, etc.
Description
The utility model relates to liquid level control apparatus.
At present, fluid level controller has polytype, and most of its structure more complicated is particularly matched by various electronic circuits, and disposes certain electronic installation, so its cost is higher.In addition, also have easily, formed by spring, ball float, contact, but its function ratio is more single, can only control a kind of liquid level, or on certain specific occasion, use, for example, the liquid level control of flood control usefulness, can not be used to control the tank liquid level as family uses, and the spring major part of using is all vertically placed, and spring is subjected to pulling force for a long time and is out of shape, and causes control malfunctioning.
The utility model purpose provides a kind of simple in structure, and multi-usage is controlled reliable leve automatic controller.
The technical solution of the utility model is to be that it is by box body, ball float, spring, contact is formed, it is characterized in that upper contact head (7) is installed in upper box cover (2), switch (6) is housed on box body (1), following contact (8), reed (5) has moving contact (11), reed (5) front end connects an end of spring (4), the rear end of reed (5) is placed on bearing (15-1), (15-2), the other end of spring (4) is connected with contiguous block (10), one end of spring (3) is connected with reed (9) front end, the other end of spring (3) is connected with contiguous block (10), and reed (9) front end is placed on bearing (15-1), (15-2), the rear end is placed on the bearing (16), contiguous block (10) is gone up system flexible cord (22), going up system at flexible cord (22) has ball float (12), ball float (13), and there is weight (14) lower end.Gravity and spring (4) by ball float, the pulling force of spring (3) forms the variation of different power, when the gravity of ball float greater than spring (3), during the pulling force of spring (4), contiguous block (10) moves down, spring (4) is drop-down with reed (5), moving contact (11) is contacted with following contact (8), when the gravity of ball float less than spring (3), during the pulling force of spring (4), spring (3), (4) shrink, contiguous block (10) moves up, at this moment reed (5) pops up, moving contact (11) contacts with upper contact head (7), and ball float (12), in succession by flexible cord (22) between the ball float (13), the spacing of two ball floats, two liquid levels of spacing control up and down, this spacing can be adjusted according to the requirement of actual liquid level control, upper contact head (7) is connected with contact (19) in the switch (6) with lead, following contact (8) is connected with contact (21) in the switch (6) with lead, contact (20) is connected with output wiring terminal (18) with lead, reed (5) is connected with output wiring terminal (17) with lead, from electrical principle as can be seen, can connect upper contact head (7) or descend contact (8) can make different purposes by switch (6), for example: do to drain off floodwaters the time spent, switch (6) upper contact (19) should be communicated with contact (20), at this moment, liquid level is low, the gravity of ball float is big, spring (3), (4) left behind, reed (5) is downward, and moving contact (11) contacts with following contact (8), following contact (8) is connected with contact (21), and at this moment contact (21) is empty.So, not output.Because buoyancy function gravity is less than spring (3), the pulling force of spring (4), at this moment spring shrinks, reed (5) pops up, moving contact (11) contacts with upper contact head (7), at this moment by lead with upper contact head (7), switch contact (19), (20) and output wiring terminal (18) be connected, at this moment output wiring terminal (17) communicates with output wiring terminal (18), and with external starting equipment circuit communication, the device (water pump or the motor of operating a switch) that drains off floodwaters starting beginning draining, when liquid level is lower than ball float (13), ball float gravity is greater than spring (3), during spring (4) pulling force, reed (5) is left behind, moving contact (11) contacts with following contact (8), output circuit opens circuit, if as supplying water the time spent, then the contact (20) in the switch (6) is connected with contact (21), the process of its control is just opposite with above-mentioned situation, also just when liquid level is lower than ball float (13), reed (5) is downward, at this moment moving contact contacts with following contact (8), output wiring terminal (17) is on good terms logical with output wiring terminal (18) circuit, starting of pump station supplies water, when liquid level surpasses ball float (12), reed (5) is popped up ball float because at this moment buoyancy gravity descend, at this moment circuit place off state, water pump will stop operating.
The utility model is because simple in structure, electric capacity can be done bigger, some small-sized electric equipments can directly communicating by intermediate circuit, in addition, the distance of this two ball float is adjustable, range of control is wider, adds the commutation effect of switch, can be used as drain off floodwaters waterlogging and the dual-purpose liquid-level controller (LLC) of retaining.
Fig. 1 is many structural representations with leve automatic controller when liquid level is lower than ball float.
Fig. 2 is many structural representations with leve automatic controller when liquid level is higher than ball float.
Fig. 3 is many with leve automatic controller circuit connection synoptic diagram.
Below in conjunction with embodiment accompanying drawing is done an explanation.
Embodiment:
