Abstract
The utility model relates to a liquid level controller, which comprises a fixing frame, a floater, a drive rod, a switch and a contact head. The upper and the lower points of the fixing frame are provided with microswitches; the height that a human body can reach is provided with a manual switch communicated with the microswitches; the floater is fixedly arranged at the lower end of the drive rod; the contact head is arranged at the top part of the drive rod; a positioning sleeve sheathed on the drive rod is fixedly connected with the fixing frame. The utility model has the advantages of simple structure and convenient operation, and the service life of a pump can be prolonged.
Description
The utility model belongs to control device, relates in particular to the control of liquid level.
Existing automatic water-supply mainly adopts non-tower water supply, Water Level Control is to control by the hydraulic pressure in the water pipe and by the pressure switch of its interlock, when hydraulic pressure reaches certain pressure, the normally closed contact of relay is backed down by hydraulic pressure, and circuit disconnects, and makes water pump stop to supply water, when hydraulic pressure reduces in the water pipe, the relay normally closed contact recovers normally off, and circuit is connected, the pump working beginning of promptly supplying water.
Though this water supply installation has solved automatic water-supply, but because it is controlled by the hydraulic pressure in the water pipe, so when user's water, hydraulic pressure in the water pipe will reduce, water pump is starting immediately just, makes so frequently to stop the water pump Fraquent start, very easily damage, also brought great inconvenience to the user.
The purpose of this utility model provides fluid level controller a kind of easy to use, simple in structure.
The purpose of this utility model is achieved through the following technical solutions: this fluid level controller, comprise fixed mount, float, drive link, switch, contact, upper and lower 2 of fixed mount is equipped with microswitch, at the palp height of human body the hand switch that links with microswitch is housed, float is packed in the lower end of drive link, contact is contained in the top of drive link, and the locating sleeve and the fixed mount that are sleeved on the drive link connect firmly.
Putting the microswitch of being adorned on the fixed mount is normally closed point, and following some institute's dress switch is normal the battle.
On the relative sidewall of fixed mount two chute is arranged, the two ends of contact are contained in the chute.
This fluid level controller is that microswitch just starts when decline of water table to demarcates, and water pump is water supply start, therefore makes water pump reduce the number of times of opening, stopping, and has prolonged its serviceable life greatly.This fluid level controller is by buoyancy control, and is easy to use, and the structure of this product is also very simple, easy to manufacture, therefore cheap.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a wiring diagram of the present utility model.
Embodiment: be fixed with float 1, float 1 in drive link 2 lower ends and make for the lighter material of proportion, locating sleeve 3 is contained on the drive link 2, between the two for being slidingly matched, locating sleeve 3 is packed on the fixed mount 5, in the upper end of fixed mount 5 microswitch 8 is housed, and this switch is normally closed point, be fixed with microswitch 4 by the bottom, this switch is normal the battle, and the distance between the microswitch 8 and 4 is the water-head of the water supply that requires, and the bearing of locating sleeve 3 on fixed mount 5 should be lower than the bearing of microswitch.On 5 liang of relative sidewalls of fixed mount chute 6 is arranged, drive link 2 tops are fixed with contact 7, and the two ends of contact device 7 are contained in the chute 6, to play the guide effect of drive link 2 in process of rising or falling.Can touch at human body and highly to be provided with manual control part, manual control part has fuse 9, air switch 10 and contactor 11, hand switch 12 and 13, these parts are packed in the control casing 14, break down or can not use for some reason the time and usefulness, this manual control part is connected with microswitch in order to microswitch.Microswitch and manual control part are connected with the used water pump that supplies water by lead.Can install movable pulley 7 ' in contact 7 both sides, so that it is more unobstructed laborsaving in rise or dropping process.
In use, this fluid level controller is packed in the top of liquid container 15, float is contacted with liquid level, float 1 rises with the rising of water level, driving the drive link 2 and the contact 7 that are fitted together mutually with float 1 simultaneously rises, when contact 7 touched microswitch 8, circuit disconnected, and make-up pump stops to supply water, increase along with water consumption, when decline of water table to certain position, when making contact 7 touch microswitch 4, closing of circuit, water pump is water supply start again, so reach the purpose of automatic water-supply repeatedly, if microswitch breaks down or can't use because of other reason the time, can select hand switch for use.
The utility model can be used for the liquid level control in the various liquid containers.
