Abstract

This invention relates to a portable pipeline valve speed-changing opener / closer, belonging to the technical field of valves. It includes a working box and a fixing device. The working box contains a speed-changing mechanism capable of changing speeds, and the lower end of the working box has a quick-installation mechanism connected to the speed-changing mechanism. This invention can change the rotational speed of the valve switch by changing the speed of the device, thereby improving the efficiency of valve opening and closing. Furthermore, this invention enables quick engagement of the valve switch, ensuring that the valve switch can rotate with the rotating steering wheel at the top of the working box. Simultaneously, this invention can quickly engage steering wheels of different valve sizes, improving the applicability of the device.
