Detecting level performing mechanism

Abstract

The invention provides a detecting level performing mechanism. A first detecting mechanism comprises a motor, a valve rod or reduction mechanism input shaft, a sensor, a stator anti-rotating device and a control device, wherein the motor comprises a rotor and a stator; the center of the rotor is provided with a hollow shaft; a specially-shaped hole is formed in the center of the hollow shaft; thecenter of the stator is provided with a bearing mounting hole; the stator anti-rotating device is fixedly connected on the stator, and is positioned on the end surface away from the rotor; the statoranti-rotating device is fixed to the peripheral outer part of the bearing; the control device is fixedly connected to an external mechanism; the sensor is arranged between the control device and the stator anti-rotating device; and the sensor is connected to a display and a controller. According to the detecting level performing mechanism provided by the invention, a performing mechanism for detecting a valve can be a performing mechanism which can be applied in valve opening work and valve closing work, and an integrated from can reduce detecting link, on an experimental table, of equipment,and reduces equipment cost.

Description

technical field [0001] The invention relates to a torque monitoring structure of an electric actuator for torque output used by a valve. Background technique [0002] Most of the torque required for valve opening or closing and the entire operation process is only based on the theoretical design value as a reference, and it is generally not tested at the factory. Therefore, in the actual selection of actuators matching the valve, it is easy to have selection deviations. If the selection is too small, the valve cannot be opened and closed under actual working conditions. If the selection is too large, it will waste resources, and the second is that when the valve fails and other stagnation occurs, the torque control of the actuator will not be able to control. Cause damage to valve stems, valve discs and other valve components, leading to production accidents. The reason why valve manufacturers seldom test the valve torque is mainly reflected in: the original torque test de...
