Abstract

PURPOSE: To provide possibility to clean well the space between two valve elements by installing an auxiliary piston in a cylinder and operating it at the time of cleaning for putting the elements of this double construction valve into a separated position with the valve opened.
CONSTITUTION: In case first or second valve elements 7, 13 can not be closed perfectly due to an accidental intrusion of any foreign matters between the first valve element 7 and first valve seat 4 or between the second valve element 13 and second valve seat 5, leakage will happen at this point not closed perfectly. The leak liquid is however drained out through the space between first and second valve elements 7 and 13 and a leak exhaust pipe 10, and the liquids at the elbow side and at the valve chest side are not mixed with each other. When cleaning liquid is to be flushed, pressed air is fed from an auxiliary air hole 23 to put first and second valve elements 7, 13 into separated positions with the valve opened.
