Abstract
PURPOSE: To reduce the generation of water hammer action and diminish flow resistance with the valve being opened by improving the spring structure of the check valve of swing type.
CONSTITUTION: In this check valve, coil spring 7 for urging a valve body 1 fastened to a valve shaft 5 in the closed direction has spring constant which is set to a specified small value within an effective range in such a manner that the rotational moment becomes sufficient large level while the valve is closed and small level while the valve is opened. Thus, when the pumping power is interrupted, delay in closing is small, presure rise by water hammer is as small as undetectable and it becomes possible to eliminate noise caused by the water hammer and failure of the valve. Furthermore, since the spring 7 for urging the valve body 1 in the closed direction has small spring constant, the valve body 1 is fully opend with ease by increasing flow rate and loss of head can be held at very small level due to that there is caused no large change in current direction.
