摘要：NOVELTY - The device has a valve driving device (2) whose output shaft is connected with a valve shaft (6). An end of a valve base is installed at an end of an air inlet joint (8). Another end of the air inlet joint is installed with an air outlet joint (12) through a bolt (7). An output end of a high pressure storage tank (1) is connected with the air inlet joint through a pipeline. The valve shaft is connected with a sensor (5) by a first shaft coupling (16). The valve driving device is connected with the sensor by a second shaft coupling (4). USE - Complex working electric valve dynamic torque continuous test device for use in designing and manufacturing fields. ADVANTAGE - The device can continuously measure and record a dynamic torque numerical value of working valves through the sensor so as to detect dynamic torque of the valve for opening and closing the electric valve. DETAILED DESCRIPTION - The valve base includes a Labview (RTM: system-design platform and development environment for a visual programming language) platform based industrial control machine (23). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a complex working electric valve dynamic torque continuous test device. High pressure storage tank (1) Valve driving device (2) Shaft couplings (4, 16) Sensor (5) Valve shaft (6) Bolt (7) Air inlet joint (8) Air outlet joint (12) Labview platform based industrial control machine (23)
