CONTROL VALVE WITH BALANCE-HALL FOR CONTROLLING FLUID FLUX

摘要

The present invention relates to a control valve including a balance hole for controlling a fluid. The control valve installed on a path to allow a fluid to flow comprises: a valve body part including a body including an inlet and an outlet in order to allow a fluid to flow in and to flow out, a cage embedded in the body and including a flowing hole to allow a fluid to pass through a lateral part while having a hollow column form whose both surfaces are opened, and a disc embedded in the cage for opening and closing the flowing hole while being moved by a stem with which one end part is combined; and an operating means mounted on the body while inducing the movement of the stem. The operating means includes: a connecting part mounted on the body and including a first body wherein the other part of the stem is located; and a motor actuator including a working rod, with which the other end of the stem is combined, mounted on the first body to induce the movement of the stem and the disc as the working rod is reciprocating. As some of a fluid flowing through a balance hole flows into a disc, the uniform flow pressure of the fluid with respect to the movement of the disc can be maintained.
