A valve system for fluid pipes is disclosed. This valve system is designed to be operable using pneumatic pressure or using another means, such as a valve control lever or fluid pressure, in place of pneumatic pressure and is designed to be controlled easily and precisely. The valve body (20) is thus movable within the passage (13) while minimizing frictional force between the valve body and the valve housing (10). The valve control lever (50) is operated in conjunction with the annular guide groove (24) formed on the circumferential external surface of the pressure actuated flange (25) of the valve body (20). In such a case, the linear moving direction and moving distance of the valve body is determined by the rotating direction and rotating angle of the lever (50). The valve system of this invention also has a rotor (40) used for centrifugally forcing the fluid introduced into the passage. A fluid guide rod (45) axially extends along the center of the passage, thus guiding the flow of fluid. A fluid guide member (33), having a variety of fluid guide surfaces, is assembled with a disc (30). The valve system thus allows fluid to more quickly and smoothly pass through the valve system. The valve body is also movably and concentrically supported by a plurality of spring-biased valve support units (26). |
