Title:
FLOW RATE CONTROL VALVE
Document Type and Number:
Japanese Patent JPS57129981
Kind Code:
A
Abstract:
PURPOSE:To control the temperature of hot-water supply to a constant by controlling the valve opening inresponse to the hot-water temperature at the outlet. CONSTITUTION:A temperature sensor 10 monitors the temperature of hot water supplied through a hot-water supply tube 3. If the detected temperature is lower than the preset temperature given to a control unit 11, a signal is transmitted to a flow rate control valve 6 installed in the main gas passage 5, so that the rotation speed of a motor 12 is increased. As a result, a pendulum 16 is expanded, bringing a valve body 17, connected to the pendulum through an arm 18, off the valve seat 19, so that the flow rate of fuel gas is controlled in proportion to the resultant valve opening.
