Abstract

PURPOSE: To detect the working condition of the valve from exterior, and, by sending this datum to the inspection center, to detect the breakage and disorder of the valve as swiftly as possible.
CONSTITUTION: To the main body of valve 1, a valve that opens and closes two bored water inlet holes is made with a magnetic substance such as iron or ferro- alloy. Opposite to valve 6, an electromagnet 24 which is eneased inside cylindrical case 23 of a detection device that can regulate advance-and-recession amount and a coil that is wound up thereto are counter posed to each other inside the main valve 1. To suction water, said valve 6 is opened with sucked-up water and when the distance between valve 6, electromagnet 24 and the coil is near, or when it is distant, the magnetic influx density that passes through the coil is changed accordingly. This fluctuation is extended to the oscillation circuit, amplification circuit and relay two-step amplifying device, by which the condition of the valve being open or closed is detected. this is indicated by red or blue lights on the panel and is checked at the inspection center apart from the valve main body.
