    • A heat exchanger, intended for use in hot water heaters, in which a tank and a hot water inlet pipe are formed integrally with each other, at a junction of which is placed a valve for control of the flow rate of hot water. The valve has a valve body disposed in close contact with a valve seat for rotation about its own axis relative thereto. Secured to the valve body is a rotary shaft which can be operated from outside. The valve body and the valve seat have respective through holes formed therein which can register with each other with their registered area variable to vary the flow rate of hot water with a change in the registered area of these through holes. The valve body is adapted to be placed in tight contact with the valve seat substantially solely by the pressure of hot water in the inlet pipe.
    • 一种用于热水加热器的热交换器,其中容器和热水入口管彼此一体形成,在其接合处设置有用于控制热水流量的阀。 阀具有与阀座紧密接触设置的阀体,用于围绕其自身的轴线相对于其旋转。 安装在阀体上的是可以从外部操作的旋转轴。 阀体和阀座具有形成在其中的相应的通孔,其可以以其登记面积可变地对准,以随着这些通孔的登记面积的变化来改变热水的流量。 阀体适于基本上仅通过入口管中的热水的压力与阀座紧密接触。
