Motor operated valve performance tester with LOCA chamber

It will be directed to a performance test: (Motor Operated Valve MOV) driver device, and more particularly, the invention the invention is motor-driven valve with a loca chamber (LOCA chamber) for testing the performance of the electric parts installed in the power plant measure the motor operated valve (MOV) Cycling aging tests and the rotational force thrust (thrust) to verify the torque (torque) and the axial force to verify to verify the reciprocating movement of the actuator such as a virtual environmental conditions of the nuclear power plant design based on simulated incidents inside Rocca chamber relates to a performance test of the motor driving the valve actuator with the loca chamber that can perform the performance tests required by installing the motor-operated valve (MOV) device driver. The invention and Rocca chamber 10, the stem shaft (15) projecting on one side to the outside is installed, is provided in the interior of the loca chamber 10, the motor driving test object is coupled to the stem axis 15. To this end, the torque meter valve actuator 20, a torque meter (30) electrically coupled to the stem shaft 15 protrudes to the outside is measured and a torque of rotating the stem axis (15) of the loca chamber (10), ( in the stem axis (15) is combined with the performance of the motor-driven valve actuator with a loca chamber with load application means for applying a load to the stem axis 15, the test apparatus from the rear end 30), said load applying means is a stem shaft 15 is inserted is formed in the part 16 the spiral at one side inner peripheral surface to be coupled to the spiral the stem shaft 15, a hydraulic cylinder 40 having a cylinder rod (41b) for leading or feeding motion in accordance with the normal and reverse rotation and a fluid which is connected to the hydraulic cylinder 40, line 42, the fluid Of 42 is formed on the needle valve 44 for opening a flow passage to flow to the hydraulic cylinder 40, the fluid in the fluid tank 48, the flow control valve 46 is arranged to control the amount of movement of the fluid and, it consists of a fluid tank (48) connected to said fluid line (42); The motor operated valve (MOV), the actuator 20 and the torque is connected to the meter 30, the rotating torque and thrust through the operating time and cycling, the current and voltage information that is applied to the motor-driven valve of the motor driving the valve actuator (20) It is the measurement unit 25 for measuring and the like, each equipped with a made structure.
