Sometimes a flow control valve operates to maintain a constant flow rate, but the flow rate controlled by it changes not only due to changes in pressure, but also when the temperature of the hot water or water being supplied changes. The present invention relates to an improvement in an automatic flow rate regulating valve in a hot water supply facility that can be automatically changed and controlled even when changes occur.

In other words, the ventilated pipe of the flow control valve, which uses the ventilated pipe to control the operation of the valve and vary the opening degree of the valve port, is fixedly provided in the flow path within the valve box. We found that by installing a needle valve in the constriction of the ventilate tube so that it can move forward and backward, it functions as a valve port that changes and adjusts the flow rate. A thermoelement whose actuating portion is telescopically operated is arranged such that the direction of its telescoping action is along the direction of movement of the needle valve, and the thermoelement controls the movement of the needle valve with respect to the valve opening. This was completed based on the knowledge that this would enable it to operate properly as a temperature control valve.
