Description
Technical field
The invention is related to a kind of moment of torsion of the electric operator of the high pulling torque output used for large size valve
Monitoring of structures.
Background technology
Valve opening or closing and during whole service required moment of torsion mostly be according to Theoretical Design value conduct
With reference to typically not carrying out factory testing to it.Therefore easily there is type selecting when actually from the executing agency with valve matched inclined
Difference.Type selecting is too small can cause under actual condition cannot opening/shutting valve, first it is waste of resource that type selecting is excessive, is second in valve
During the catching phenomena such as failure, the moment of torsion control of executing agency does not have control action, causes the valve parts such as valve rod, flap
Damage, cause the generation of production accident.Why valve producer seldom carries out torsion-testing to valve, its reason major embodiment
：Original torsion-testing apparatus test result is inaccurate, test device installation difficulty, test it is cumbersome, especially big specification is big
Bore valve, valve producer is even more without corresponding test device to test valve.
Original test device typically uses two kinds of forms, and one kind is direct measurement, and another kind is measurement indirectly.Directly survey
The test device of amount is aided with hand gear and is surveyed directly to use torsion-testing apparatus, such as torque sensor, torque wrench etc.
Examination, but this test additionally depends on the practical operation of operator, and during real onsite application it is often electronic, the speed of its operation
Degree can be fast more a lot of than manual, and this causes its operational efficiency inconsistent, and the torque value measured also just has gap, especially for big
The keying of specification large bore valves, measurement result has been even more larger gap, and this type selecting to executing agency produces considerable influence.And
And the test implementation of this mode gets up very cumbersome, install also difficult, be not suitable for being tested when factory dispatches from the factory, be only suitable for
In the type approval test stage of product.
Measurement indirectly is exactly that the selection and deployment executing agency that has moment of torsion display function is tested valve.Band originally subtracts
The executing agency of fast device is all to realize that moment of torsion is detected in revolution more than one-level.As the patent No.：ZL201010589531.0 is invented
Title：Described in the Chinese patent of high-torque valve torque monitoring system, as shown in figure 1, high pulling torque electric valve executing mechanism

It is mostly use Multi-stage transmission to need the executing agency's drive mechanism being equipped with, thus it is at different levels between transmission efficiency and transmission
Stability determines test result.
In order to monitor and examining the combination property of executing agency, while executing agency can be protected in operation,
Need to carry out the dynamic torque and stroke of executing agency real-time, accurate monitoring, and according to the torque data and row of collection
