Electromechanical double-control water supplementing device

Abstract

The invention relates to the technical field of water supplying equipment, in particular to an electromechanical double-control water supplementing device. In the electromechanical double-control water supplementing device, an electromagnetic valve is connected to a water supply pipeline, and when a floating ball valve works normally, the electromagnetic valve is in an opening state; a high-water-level sensor and a low-water-level sensor are embedded in the inner wall of a box body; the height of an induction part of the high-water-level sensor is larger than the liquid level of water in a water supplementing cavity when the floating ball valve is in a completely-closed state; and a control module is electrically connected with the electromagnetic valve and the liquid level sensors and isused for receiving electric signals sent by the high-water-level sensor and the low-water-level sensor and controlling closing or opening of the electromagnetic valve. When the floating ball valve breaks down, the control module receives corresponding electric signals sent by the high-water-level sensor, the electromagnetic valve is controlled to be closed, and water supplementing to the interiorof the box body is stopped; the control module receives corresponding electric signals sent by the low-water-level sensor, the electromagnetic valve is controlled to be opened, and water supplementingto the box body is continuously conducted; and the operation is repeated in such a way, and therefore the water supplementing device can still work normally when the floating ball valve fails.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to an electromechanical dual-control water supply device. Background technique [0002] Existing devices for supplying water to equipment or systems are generally float tanks, and ball float valves are arranged in the float tanks. Float valve is a valve composed of crank arm and floating ball, which can be used to automatically control the liquid level of water tower or pool. The float must always float on the water, and when the water level rises, the float also rises. When the float rises, the connecting rod also rises. The connecting rod is connected with the valve at the other end. When it rises to a certain position, the connecting rod supports the rubber piston pad to close the water source. When the water level drops, the float also drops, and the connecting rod drives the piston pad to open. The water replenishment is controlled by the float valve, because...

AI Technical Summary

Problems solved by technology

When the above-mentioned water tank is used for water replenishment, when the float valve fails, it can only control the solenoid valve to start and close the water inlet pipe, and the water replenishment can only be continued after maintenance, which will affect the subsequent water replenishment operation of the equipment
