Abstract
The invention relates to an intelligent detection device for a control valve. The intelligent detection device for the control valve comprises a positioner connected to an inlet air path of a pneumatic execution mechanism. The pneumatic execution mechanism can be connected to a valve rod of the valve to be detected and drives the valve to be detected to open or close. The intelligent detection device for the control valve further comprises a linear displacement sensor, and a detection end of the linear displacement sensor can be connected to the valve rod and moves vertically along with the valve rod. A signal output end of the linear displacement sensor is connected to a programmable controller module, a control signal output end of the programmable controller module is connected to a control module of the positioner, and the programmable controller module is further connected to a storage module and a touch display input/output module. The intelligent detection device for the control valve is used for detection, high in detection speed, capable of analyzing detected data and high in detection accuracy.
Description
Technical field
The present invention relates to a kind of intelligent detection device for detection control valve.
Background technique
According to NBS requirement, before control valve dispatches from the factory, must experimental test be carried out, wherein intrinsic error, return difference, dead band, to put the control mechanism travel parameters such as deviation, rated travel deviation be all the time essential items for inspection.And domestic manufacturers are utilize dial gauge to adopt the mode of manual measurement to carry out to the detection of these parameters substantially, measuring speed is slow, precision is low, artifical influence factor is large, can not form electronic data, cannot realize automation, intelligentized observing and controlling.
Summary of the invention
Technical problem to be solved by this invention is, provides the control valve intelligent detection device that a kind of detection efficiency is high, testing precision is high.
Control valve intelligent detection device of the present invention, comprises a positioning work piece be connected on pneumatic actuator airway, and described pneumatic actuator can be connected to be treated on the valve rod of side valve, drives and treats that side valve opens or cuts out; It also comprises a linear displacement transducer, and the test end of described linear displacement transducer can be connected on valve rod, moves up and down with valve rod; The signal output part of described linear displacement transducer is connected to programmable controller module, the control signal output terminal of described programmable controller module is connected to the control module of positioning work piece, and described programmable controller is also connected to memory module and touches display input/output module.Utilize control valve intelligent detection device of the present invention to detect, detection speed is fast, and can to the data analysis detected, and testing precision is high.
Side valve is treated for different size, need the position adjusting linear displacement transducer, so linear displacement transducer is arranged on sliding sleeve, described sliding sleeve is enclosed within a vertical traveller, described sliding sleeve can slide along traveller, and can be fixed on traveller by locking element, improve the Applicable scope that control valve intelligent detection device treats side valve.
