Abstract

The utility model is aimed at providing a water tower for automatically controlling water feeding. The water tower is composed of a tower body, a water inlet at the upper portion of the tower body and a water outlet at the lower portion of the tower body. A guide tube is fixed on the tower body, a sliding bar is arranged in the guide tube, a floating ball is fixed at the lower portion of the sliding bar, which is further fastened with a floating ball, and the upper portion of the sliding car controls a crook-spring handle of the power switch. The way for the upper portion of the sliding bar controlling the crook-spring handle of the power switch is that when the crook-spring handle downwards bears two floating balls' weight, the crook-spring handle turns the power switch for energizing, when the crook-spring handle upwards bears the fixed floating ball's buoyancy, the crook-spring handle turns the power switch for current interruption. The floating balls pull the power switch for on-and-off by the action of the liquid buoyancy and the floating balls' gravity, thereby controlling the on-and-off of the water pump motor, with simple structure, convenient installment and maintenance, less maintenance load and low cost.

Description

A kind of water tower of automatic control water inlet

Technical field

The utility model belongs to a kind of water tower of automatic control water inlet.

Background technology

The fluid level controller of critical piece (water) automatic control of liquid that is used for automatic control such as water tower, pond of prior art mainly contains following three kinds of structures: one, electronic liquid level controller.The controller of the automatically controlled water pump motor start-stop of forming by electronic devices and components such as transistor, plain conductor and electrodes.Its major defect is: because control loop works long hours, easily make components and parts service behaviour reductions such as transistor, and produce misoperation; Simultaneously, because plain conductor and electrode long period of soaking be in water, the water source had both been polluted in easily oxide etch to a certain extent, easily cause controller response to reduce again, and cost was higher.Two, ball float opens and closes the mechanical fluid level controller of water valve by lever.Owing to can not control the motor start-stop, only be fit to the control at water source from the beginning, applicable surface is very little.Three, ball float is by the mechanical fluid level controller of lever, stroke (fine motion) switch automatic control motor start-stop.Mainly contain following deficiency: because lever arm length is subjected to the restriction of water tower diameter,, can not make full use of the water tower water resource, make pump motor work too frequent again so the water-head that can control is less; And structure is complicated, and the accurate requirement that travel switch is touched is difficult to satisfy, and influences the stability of work so be out of order easily.

Summary of the invention

The purpose of this utility model provide a kind of stable working state, reliably, the water tower of the liquid level difference of not polluted source, control is big, the pump motor start/stop time is reasonable, simple in structure, cost is low automatic control water inlet.

The purpose of this utility model is achieved in that a kind of water tower of automatic control water inlet, water tower is made of the water inlet on tower body and tower body top and the delivery port of bottom, at tower body fixed guide pipe, it in the guide pipe sliding bar, a ball float and ball float of bolt are again fixed in the sliding bar bottom, the spring handle of sliding bar top control power switch.

Sliding bar top is the spring handle of controlling power switch like this: when spring handle bears the weight of two ball floats downwards, spring handle is moved the power switch energising, when spring handle upwards bore the buoyancy of fixing ball float, spring handle was moved the power switch outage.

After adopting above structure, the water tower automatic control switch is compared with the fluid level controller of prior art, has the following advantages and beneficial effect.One, because without transistor with place the metal cords of water and electrode etc., and can adopt water-feeding pipes and non-toxic plastic to make slide bar and ball float, so, can not produce secondary pollution to water (liquid), the misoperation that does not also exist components and parts service behaviour such as transistor to reduce to be produced, and the sensitivity that causes of plain conductor and anodizing reduce, simultaneously, it is very high to its accuracy of control of two microswitches to touch platform and stay cord, therefore, its stable working state is reliable.Two, because the influence that is not subjected to the water tower diameter up and down of bolt ball float so the liquid level difference of control is very big, has both made full use of water (liquid) resource of water tower (container), make the pump motor start/stop time reasonable again, prolong the application life of equipment.Three, by a ball float under buoyancy of liquid and ball float action of gravity, Drawing switch break-make, and then the start-stop of control of pump motor, it is simple in structure, it is very little to be convenient to its maintenance capacity of installation and maintenance, and cost is very low.Water tower has also produced the corresponding techniques effect.

Description of drawings

Fig. 1 is the utility model bolt ball floating structure schematic diagram.

Fig. 2 is the vertical sink structure schematic diagram of the utility model bolt ball.

As Fig. 1 Fig. 2, a kind of water tower of automatic control water inlet, water tower is made of the water inlet 2 on tower body 1 and tower body 1 top and the delivery port 3 of bottom, at tower body 1

fixed guide pipe

4,4 is sliding bars 5 in the guide pipe, a ball float 6 and ball float 7 of bolt again, the spring handle 8 of sliding bar 5 tops control power switch are fixed in sliding bar 5 bottoms.

Sliding bar 5 tops are spring handles 8 of controlling power switch like this: when spring handle 8 bears the weight of two ball floats downwards, spring handle 8 is moved the power switch energising, pump working, by water inlet 2 water inlets, when spring handle 8 upwards bears the buoyancy of fixing ball float 6, spring handle 8 is moved the power switch outage, and at this moment, water pump quits work but water tower has been full of water.
