Abstract

PURPOSE:To enhance rangeability by converting rotation into reciprocation by an eccentric shaft and a slider. CONSTITUTION:When an output shaft 2 is rotated, a main shaft 3 is rotated in the same direction as the output shaft 2 with an eccentric shaft 4 fixed to the axis of the main shaft eccentrically, so that a slider 6 is elevated together with a valve rod 9 by the eccentric shaft 4. When the valve rod 9 is lowered, and a valve body 43 closely contacts a valve seat, a piercing hole 40 functioning as a fluid passage is closed. On the contrary, when the valve rod 9 is lifted up to separate the valve body 43 from the valve seat 41, the piercing hole 40 is opened.

Problems to be Solved by the Invention 1) Conventionally, a die A7 flam type control valve has been used for the above-mentioned applications, but this has the following problems. First, since a diaphragm is used, the rangeability is small. Second, it requires a compressed air source and compressed air supply piping. Third, since it uses compressed air, it is affected by external conditions such as temperature.
Since a spring is used to return the diaphragm, hysteresis is large. Fourth, the resolution is low because it requires compressed air, a diaphragm, and a soup ring. Fifth, remote control is not possible due to the problem of pressure drop due to the use of compressed air. Finally, since the compressed air is further compressed when it reaches the diaphragm during supply, the response speed of the valve operation to the command is slow.

An object of the present invention is to provide a control valve that eliminates all of the above problems.

Effects of the Invention According to the control valve of the present invention, the valve is actuated by a pulse motor via an eccentric shaft and a sliding body that is given reciprocating motion by the eccentric shaft, so rangeability is large and a thin cable is required. Not only is it possible to use optical fibers, but the hysteresis is small and the resolution is large. Since the motor is driven by electricity, remote control is of course possible, and since the valve is operated by the motor, its response speed is much faster than that by compressed air.
