Abstract

PURPOSE:To prevent the closing time lag of a valve body and water hammering at the closing instance by decreasing the spring constant of a spring energizing the valve body to increase the lift distance of the valve body and decreasing the diameter of the valve seat opening to lessen flow resistance. CONSTITUTION:The spring constant of a coil spring 5 energizing the valve body 2 is set small, and is order to increase the energizing force when the valve is closed and to suppress the energizing force as low as possible when it is open the energizing force is set in such a way that its value for full-open valve is 1.1-1.5 times of the energizing force when the valve is closed. The opening diameter d0 of a valve seat 7 is set 0.7-0.9 times of the opening diameter of the valve body 2 in order to decrease flow resistance applied to the valve body 2 and prevent the closing time lag of the body 2. As a result, any water hammering at the instance of closing can be effectively prevented.
