DEVICE FOR SENSING RISK OF DIAPHRAGM VALVE

摘要

PURPOSE: A device for sensing risk in a diaphragm valve is provided to quickly replace a component by detecting leakage of a fluid and to prevent an accident while efficiently operating a valve. CONSTITUTION: A device for sensing risk of a diaphragm valve comprises an actuator unit(10); springs mounted on upper and lower portions of the actuator unit; a fixed shaft(16) vertically installed on the middle of a block(18); upper and lower plates elevating the fixed shaft; a stator(22) mounted on a lower end of the fixed shaft; a body(24) operated by pressing the stator; a diaphragm(28) formed on a fluid passage of the body; an operating unit(20) mounted on a diaphragm valve; a housing member(40) fixed between the actuator unit and the operating unit; a connecting member(60) elevated according to leakage of the fluid by being penetrated through the fixed shaft; a float(82) moving according to water level of the fluid; and a detect unit detecting amount of the fluid by having a lead switch unit.
