Valve actuator

Abstract

This product is connected to a valve installed in a fluid passage, such as a liquid or gas, via a mechanism that transmits rotational force. The rotational force of the motor moves the valve, opening and closing the passage and adjusting the fluid flow rate per unit time. Approximately in the center of the front side, there is an opening degree indicator that shows the degree of opening of the passage. The opening degree is represented as 0% when the passage is completely closed and 100% when the passage is completely open. This opening degree indicator is the part for which design registration is sought as a partial design. The front view and perspective view show the state when the opening degree is 50%. The opening degree indicator is color-coded so that the opening degree can be seen at a glance. To explain this using an enlarged front view showing only the partial design portion when the opening degree is 50%, the fan-shaped area in the range from 0% to 50% is colored green, and the fan-shaped area in the range from 50% to 100% is colored red. As the opening degree increases, the green area becomes larger, and when the opening degree reaches 100%, the red area disappears, and only the green area remains.
