Abstract
The present ivnention relates to a water level control switch for water tower, including two floats, one of them is used for connection and another is used for shtutoff, and it is characterized by that its interior of equipped with a magnetic-iron and an iron plate, after the iron plate and magnetic iron are separated each from other by means of float gravity, the contacts are connected to the water pump can be started to pump with, and when the water level is risen and two floats are floated, the iron plate can be attracted by magnetic iron, they are engaged together, and the contacts are separated, said control switch is powered off.
Description
The present invention relates to a kind of switch, especially a kind of water level control switch for water tower, present most water tower manual control switch fetch water, and inconvenience easily causes power and water waste.
The present invention realizes by following measure, is provided with through hole in the middle of its feature magnet 1, and 2 times centres of iron plate are provided with pull bar, and pull bar pulling iron plate is left magnet, and the contact loses thrust and closes, at this moment energising.Iron plate 2 is by adhesive, and contact 4 is open, outage.
The present invention has following good effect, can the automatic switch power supply, and method is brief, and is durable, and saving of work and time is saved the water source.
Below in conjunction with accompanying drawing best enforcement of the present invention described in detail.
Figure of description is the embodiment of the present invention structural representation.
Referring to figure: a kind of water tower level automatic control switch, it comprises shell 8, contact 3, fixed head 7, two praps 4 are provided with through hole in the middle of the float 5 and 6, magnet, and bottom is provided with the pull bars of ining succession in the middle of iron plate 2, the iron plate 2, and the contact is provided with push rod.Float 5 and 6 is put in the water tower 10, and last float 5 plays the pass effect, and following float 6 works out effect.
When using, water tower is anhydrous at the beginning, and iron plate 2 is left behind in the action of gravity by 5 and 6, the contact loses the thrust of iron plate 2, and the elasticity by the contact makes engage contacts, at this moment energising, water pump draws water, when water level rises, float 6 loses weight, and in light weight because of float 5 can be kept iron plate 2 and do not sucted by magnet 1, and the maintenance "on" position treats that the water level rising is risen float 5, and at this moment float 5 and 6 all loses weight, iron plate 2 is sucted, and at this moment the contact is pushed open by iron plate 2, outage.
After the outage, drawdown, float 5 leaves the water surface, because iron plate 2 has been left the magnet certain distance, magnet suction reduces very big, so can not be sucted, but can be kept contact 3, treated that float 6 also leaves the water surface in off-state, common weight by float 5 and 6, again iron plate 2 is drawn back, energising again, water pump draws water, thereby reach the purpose of going round and beginning again, can control automatically.
Claims (4)
