Abstract

The utility model relates to a pressure differential adjusting device, wherein the device includes: the regulating valve group is connected with the output end of the gas in the electrolytic cell and is provided with at least two pneumatic regulating valves which are mutually connected in parallel; the valve positioning group is provided with valve positioners corresponding to the number of the pneumatic regulating valves, and the valve positioners are respectively and electrically connected with the control ends of the corresponding pneumatic regulating valves; and the controller is electrically connected with the valve positioner of the valve positioning group and used for sending a control signal to the valve positioner, and the valve positioner controls the opening and closing degree of the corresponding pneumatic regulating valve step by step according to the control signal. The valve positioner can control the degree of opening and shutting of the pneumatic control valve that corresponds step by step according to the size of the control signal that the controller sent, and the regulation range in the pressure differential adjusting device is wideer like this, precision and sensitivity are higher to, on the basis of current structure, do not increase extra control output point, guarantee to control simply high-efficiently and the regulation range in the pressure differential adjusting device is wideer like this, precision and sensitivity are higher to, on the basis of current structure, do not increase extra control output point, guarantee to control simply high-efficiently and the regulation range in the pressure differential adjusting device is wideer like this, precision and sensitivity are higher to, on the basis of current structure, do not increase extra control output point, guarantee to control simply high-efficiently.
