Abstract

PURPOSE:To control a fluid proportional control valve surely, by detecting the temperature change of a permanent magnet of a valve material, which has the permanent magnet and an electromagnetic coil and is driven by changing the power supply quantity of the electromagnetic coil, to compensate the current value of the coil. CONSTITUTION:A fluid proportional control valve 21 consists of a fluid inlet 8, a fluid outlet 9, a valve seat 10, and a valve body 11, and a diaphragm 12 is provided in the upper part to keep the pressure in the side of the fluid outlet 9 constant against the pressure change in the side of the fluid inlet 8. Permanent magnets 13, a center pole 14, a top yoke 15, and a bottom yoke 16 constitute a magnetic circuit. An electromagnetic coil 18 is wound around a coil bobbine 17 in the magnetic gap. A temperature sensor 20 is fitted between or near permanent magnets 13 to drive a temperature compensating circuit 22. For example, a signal, which compensates the temperature change of the fluid proportional control valve 21 of a gas water heater, and the output signal of a water temperature detecting element 5, which is provided in the upper stream of a heat exchange 4, are inputted to an electric control circuit 6 to control the fluid proportional control valve 21, thus obtaining always hot water at a desired temperature.
