Embodiment Construction

[0008] water connection see figure 1 As shown, the water outlet (3) of the solenoid valve body (2) is connected to the water inlet (5) of the water flow sensor with a sealed connector (4). Water outlet (7) connects house water pipe.

[0009] See the circuit connection figure 2 As shown, the control circuit power supply plug (10) is connected to the indoor 220V AC socket, two signal wires of the flow sensor (11) and the control circuit module (9), and the output of the control circuit module (9) is connected to the solenoid valve coil (8).

[0010] After the waterway and the electric circuit are connected correctly, open the main inlet valve and it can be used. The solenoid valve is normally kept open. When there is water flowing, the water flow sensor sends out a signal. The control circuit receives the signal and confirms whether the duration exceeds the set value. Once the set value is exceeded, the control circuit outputs a signal to drive the solenoid valve coil and clo...

Abstract

The invention relates to a domestic automatic control water valve which is a device used for preventing long-time continuous water leakage because of various reasons of users. The device is composed of a water flow sensor, a control circuit, a solenoid valve and a sealing connecting piece, wherein the water inlet of the water flow sensor is connected with the water outlet of the solenoid valve in a sealed mode; a signal wire of the water flow sensor is connected with the control circuit; the output electrode of the control circuit is connected with a coil of the solenoid valve. The device can be used in family houses and the like, and can automatically turn off the water valve when the time of continuous water leakage exceeds the time limit, thus effectively preventing water resource waste caused by water leakage of toilets, control failures of solar water heaters, breaking of water pipes and opening of taps during water outage, etc.

Description

1. Technical field [0001] The invention relates to an automatic control valve for preventing leakage of running water and belongs to the technical field of valve detection and automatic control. 2. Background technology [0002] The main water valve for tap water in households and other places generally adopts a copper spherical water valve, which requires a manual switch. Generally, it remains open and will only be closed when the pipeline is repaired. In the daily life of the family, if no one is at home for a long time, the tap water will flow out for a long time due to problems such as the aging of the toilet sealing cap, the failure of the automatic controller of the solar water heater, the damage of the faucet, the burst of the water pipe, and the opening of the faucet when the water is cut off. To solve these problems, there seems to be no better way than selecting high-quality and high-performance materials and strengthening artificial precautions. The selection of ...
