Title:
AUTOMATIC STOP DEVICE OF WATER
Document Type and Number:
Japanese Patent JPS5861374
Kind Code:
A
Abstract:
PURPOSE:To both reduce flow line resistance of a device and decrease its vertical height, by positioning an impeller in a water quantity detecting chamber, in a linear flow water passage between a globe valve hole and delivery water port, under a condition approximated with a vane part to a valve hole. CONSTITUTION:A supply water pipe receiver part 2, water stop chamber 4, vane part of an impeller in a water quantity detecting chamber, and delivery water port 3 are arranged in a straight line, and pipe line resistance and loss are decreased to improve delivery efficiency. While the vane part of the impeller 6 is located immediately below a valve hole 51 of a globe valve 5, and good linearity of a flow and speed of the impeller 6 can be obtained. Then a vane 16 in the water quantity detecting chamber is arranged in a linear flow water line between the valve hole 51 and the delivery water port 3 in such a manner that the vane part is approximated to a lower end opening of the valve hole 51. Accordingly, only the valve hole 51 of the globe valve 5 is provided between the water stop chamber 4 and the impeller 6 in the water quantity detecting chamber, and the vertical linear state flow water line, from the supply water pipe receiver part 2 to the delivery port 3, is obtained, while vertical dimensions can be decreased.
