Check valve for detecting water leakage and water leakage alarm system using the same

Abstract

The object of the present invention is to provide a device which can frequently detect water leakage with simple equipment and issue a water leakage alarm. Regardless of whether it is natural water leakage caused by aging water pipes or human-made water leakage, such as forgetting to turn off the water tap, failure of heating equipment, and operational errors, it can be dealt with. The water leakage alarm system in the present invention includes two main parts: the water leakage detection check valve, which can detect the movement of the mover and transmit the detection signal of the movement of the valve body; A valve body moves in the same way; the signal processing device analyzes the detection signal from the water leakage detection check valve and activates the water leakage alarm. The water leakage detection check valve has a main valve and a sub valve. When a large water leakage is caused by human beings, the main valve operates. When a small water leakage occurs naturally, the sub valve operates.

Description

technical field [0001] The present invention relates to a water leakage detection check valve and a water leakage alarm system using the check valve. In particular, the water leakage detection check valve has a structure capable of detecting the movement of the valve body of the check valve installed in the water pipe. The water leakage alarm system has the water leakage detection check valve and a signal processing device, the signal processing device receives the detection signal from the water leakage detection check valve, analyzes it, and starts an alarm. Background technique [0002] Leaky water pipes in buildings not only cause an unnecessary increase in water bills, but also cause damage to houses and property losses depending on the degree or location of the leak, causing a lot of trouble to residents. Especially in dense housing like condominiums and hotels, one water leak can wreak havoc on most of the underlying units and rooms, which happens quite often in real ...

Problems solved by technology

This invention is aimed at detecting the tiny water leakage that occurs naturally, compares the allowable water flow rate under the situation of no water leakage with the water flow rate under the situation of not using water, and judges whether there is water leakage (see patent document 4), so it cannot be artificially detected. React to the leak caused by
