Abstract
The utility model relates to a water inlet controlling device of a water tank, comprising an inching switch arranged in a controlling box which is mounted on the top portion of the water tank, and the inching switch is connected with an outer controlling power circuit. A trigger batten is engaged with a press-button of the inching switch, one end of the trigger batten is fixedly connected to the inching switch, the other free end is cascaded with an upper floating ball and a lower floating ball which are arranged in the water tank via a leptctene, wherein the weight of the upper floating ball equals the buoyancy to which the floating ball is subjected, the torque that the upper floating ball exerts to the trigger batten equals the torque produced by the press-button of the inching switch. The utility model has the advantages of simple structure, damage resistance, capability of automatic controlling, and good security without contact of the power circuit and the water.
Description
The utility model relates to a kind of inlet control device of controlling the water tank pondage.
Present water tank water intake control device is a kind of to be to adopt ball float and connecting rod to control the switching of water intaking valve.The power that ball float is subjected to is quite big by the moment that connecting rod acts on water intaking valve, and water intaking valve damages easily.Cistern water level one reduces, and ball float just descends, and it is frequent that water intaking valve is opened and closed, and accelerated damage.Need water pump to supply water at some high-rise water tanks, adopt the floating ball rod formula to be difficult for realizing water pump control.Also have a kind of employing search switch to be located in the water tank now, utilize water level whether to flood search switch and control water inlet.This mode circuit contacts with water, and unsafe factor is arranged, and fragile equally, the installation and maintenance inconvenience.
The utility model purpose is that design is a kind of simple in structure, and safety is good, is convenient to the water tank water intake control device of control automatically.
The utility model is provided with control box in tank top, microswitch is located in the control box and circuit connects the external control electric power loop, triggering press strip one end that cooperates with the button of microswitch is fixedly connected on the microswitch, another free end is connected with of fine rule, the fine rule other end is connected with the upper floating ball that is positioned at water tank, and following ball float is connected in the upper floating ball below by line; The buoyancy that the weight of following ball float and himself fully is not subjected in the entry equates, the weight of upper floating ball acts on the moment that triggers the press strip fixed end and equates by the button that connects that fine rule acts on the moment that triggers the press strip fixed end and microswitch.
When water level rises to the upper floating ball lower limb, the button of microswitch acts on the moment that triggers press strip to the moment that triggers press strip greater than ball float by fine rule, microswitch push-button is upspring, and cuts off the power supply of outside supply-water pump or water inlet pipe electromagnetic valve, and water tank stops into water.Then microswitch connects button and is pressed water tank water intake when drawdown is extremely descended the top edge of ball float.The utility model is simple in structure, and is not fragile, can control automatically, and circuit does not contact with water, and safety is good.
Further illustrate the utility model below in conjunction with drawings and Examples.
Accompanying drawing is that the main structure of embodiment is provided with schematic diagram.
As shown in the figure, water tank 7 tops are provided with control box 1, and microswitch 2 is located in the control box 1 and circuit connects the external control electric power loop.If it is architectural that water tank 7 is positioned at higher level, microswitch 2 can connect the electric power loop of supply-water pump, can certainly establish electromagnetic valve on the water inlet pipe 8 of water tank 7, and microswitch 2 connects electromagnetic valve as switch.Triggering press strip 3 one ends that cooperate with the button of microswitch 2 are fixedly connected on the microswitch 2, and another free end connects the upper floating ball 5 that is positioned at water tank 7 by fine rule 4, and following ball float 6 is connected in upper floating ball 5 belows by line.The weight of following ball float 6 and its body are established the buoyancy that is subjected in the entry fully and are equated, the weight of upper floating ball 5 acts on the moment that triggers press strip 3 fixed ends by the button that fine rule 4 acts on the microswitches such as moment 2 of the fixed end that triggers press strip 3.Like this, before water level no show upper floating ball 5 lower limbs, the button of microswitch 2 is connect down always, and water inlet pipe 8 is intake always.Equally, before water level did not drop to the top edge of ball float 6, water inlet pipe 8 was closed always.When just water level changes between upper floating ball 5 lower limbs and following ball float 6 top edges, microswitch 2 will maintain the original state constant, can avoid the frequent switching of supply-water pump or electromagnetic valve like this.
Claims (1)
