Abstract

PURPOSE: To reduce driving force at the beginning of the opening and closing of a valve body by changing fluid pressure functioning to the valve body into the operating force of the opening and closing of the valve body.
CONSTITUTION: Two valve bodies 3 are integrally mounted to a valve spindle 4 continuously, and a valve is opened and closed by the revolution of the valve spindle 4. Fluid pressure at the upper stream side of a flow path functions to the valve bodies 3 by opening an opening and closing valve 7 of the first flow path a while closing an opening and closing valve 8 of the second flow path (b) when closing the valve, resultant force W at that time works to a virtual uniting and dividing valve body section 3a at the upper stream side at the larger pressure receiving area side, and operating force opening the valve bodies 3 is generated. Resultant force W functioning to the valve bodies 3 works to a virtual dividing valve body section 3a at the upper stream side, pressure receiving area thereof is larger, by closing the opening and closing valve 7 while opening the opening and closing valve 8 when opening the valve, and operating force opening the valve bodies 3 is generated.
