Abstract

PURPOSE: To protect sheets from wear that is possible caused at the time of opening and closing a ball valve, by turning a valve body with the sheets being spaced apart from each other while keeping the valve closed.
CONSTITUTION: Transportation of fluid is accomplished and interrupted by switching the valve condition between the state that a valve body sheet 8 is held in tight contact with a valve box sheet 9 and the state that a through-hole 4 is communicated to a conduit. The second valve element 5b having the valve body sheet 8 is coupled to the first valve element 5a having valve roeds 6, 6 connected thereto, in the manner that the second valve element 5b can be moved feely toward and away from the valve box sheet 9 while keeping the valve closed. On the other hand, the valve rods 6, 6 are disposed to be slidable only in the axial direction of a valve actuating mechanism 7 and the first valve element 5a and to be slidable and rotatable to a valve box 3. At the same time, the valve rods 6 are connected to the second valve element 5b via a linkage 10. Further, a pin 13 fixed to the valve rod 6 is fitted in a cam groove 12, so that the second valve element 5b can be moved toward and away from the first valve element 5a by vertically moving the valve rods 6 automatically at the time of opening and closing the valve.
