Abstract

PURPOSE: To secure well water sealing capacity over a long period of time by adjusting the fastening margine by providing the ring-shaped sleeve which is movable in the direction of the fastening margine at the sheet part.
CONSTITUTION: When the water sealing ring 32 of the biplane valve is worn out in the process of the use for a long period of time, the adjusting bolt 26 is tightened to shift the movable sheet 24 to increase the fastening margine as much as the amount of wearing of the water sealing ring 32. By doing so, the fastening margine of the sheet part 24A and the water sealing ring 32 can be maintained appropriate without giving too much distortion to the water sealing ring 32 in the valve desk 31, and the life of the water sealing ring 32 can be prolonged and well water sealing capacity can be maintained for a long period of time. Also, as the adjusting bolt 26 is mounted outside the waterway, the fastening margine can be adjusted quickly and easily without removing the water in the waterway.
