Title:
REMOTE OPERATION TYPE WATER DRAINAGE COCK
Document Type and Number:
Japanese Patent JPS6113078
Kind Code:
A
Abstract:
PURPOSE:To reduce the load in the case when a cock is opened by pulling-up a main valve, by installing an expandable water chamber in the connection part between a main valve and a subvalve. CONSTITUTION:When a subvalve 31 is pulled-up by an interval (a), the pressurized water in a water chamber 18 is introduced into a space 39 from a water through hole 38, passing through a hole 36 from a small hole 35 on a subvalve gland 33, and then introduced to a discharged-water port 3 side from a slidable surface 40, passing through a cut stepped part 41. Therefore, the pressure in the water chamber 18 lowers, and a main valve 14 is lightly pulled-up by the retaining force of a bellows 17. After a water discharging packing 25 closes a drainage hole 11, a communication port 4 is opened, and a sliding piece 21 rises, and when it contacts with the undersurface of a valve seat 24, the main valve 14 stops rising, and water flowing state is formed.
