The utility model changes the history of manual detecting and diagnosing of the regulating valve, and can intelligently make comprehensive detection, diagnosis, analysis to regulating valves. The utility model is highly scientific and accurate, and fills the blank field of the instrumentation regulating valve of our country, which has a great value for promotion and application.
Description
The utility model relates to the instrument that the variable valve performance fault detects diagnosis, especially a kind of instrument of variable valve performance fault intelligent detection and analysis.
At present, the detecting instrument of the variable valve of existing instrument is the cooperation by several instrument, and only is the performance state that detects variable valve, to the diagnosis of performance, fault and the failure cause of instrument variable valve, the analyzing and diagnosing instrument of the simple and practical intelligence that neither one is comprehensive.The fault of variable valve often by manually according to the operating position of variable valve, judge maintenance by the experience of oneself, so often can accurately not deal with problems, cause and repair repeatedly and can not find its main cause.
The purpose of this utility model provides a kind of variable valve performance fault intelligent detection and analysis instrument, and it can not only detect the performance of instrument variable valve, but also can to performance, fault and the failure cause of instrument variable valve comprehensive detect diagnostic analysis.
The purpose of this utility model is achieved in that computing machine (8) connects by the input end of the same signal converter of signal transmssion line (9) (10), the output signal of signal converter (10) output terminal, be connected with the input end of electropneumatic valve positioner (13) through conversion of signals transmission line (11), signal converter (10) input end is connected with displacement transducer through displacement signal transmission line (4), be connected with pressure transducer (2) through pressure signal transmission line (5), displacement transducer (15) is connected by the moving-member of unitor (14) and variable valve (1), one end of stop valve (3) is connected with pressure transducer (2) input end by gas circuit, the other end is connected with the defeated outlet side of electropneumatic valve positioner (13) by air pipe (12), the output terminal of pressure transducer (2) is connected by the air film chamber of air pipe with variable valve (1), thereby forms a complete variable valve performance fault intelligent detection and analysis instrument.
Owing to adopted such scheme, can reach instrument variable valve performance, fault and failure cause are carried out comprehensive check and analysis, the purpose of diagnosis.And, simple in structure, practical.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing is a structural principle synoptic diagram of the present utility model;
In the drawings, 1. variable valve 2. pressure transducers 3. stop valves 4. displacement signal transmission lines 5. pressure signal transmission lines 6. sources of the gas 7. steady arm connecting lines 8. portable computers 9. signal transmssion lines 10. signal converters 11. conversion of signals transmission lines 12. air pipes 13. electropneumatic valve positioners 14. unitors 15. displacement transducer a. valve stamens
In the drawings, this variable valve performance fault intelligent detection and analysis instrument, technical requirement according to the different adjustment valve, computing machine (8) is output order automatically, enter electropneumatic valve positioner (13) by signal converter (10), electropneumatic valve positioner (13) enters the air film chamber of variable valve (1) according to electric signal output gas by stop valve (3) and pressure transducer (2), control valve trim a, to the moving of b, stop valve (3) is in order to detect the sealing of variable valve (1) air film chamber.After closing stop valve (3), in official hour, detect the pressure drop-out value of variable valve (1) by pressure transducer (2).Displacement transducer (15) detects the actual displacement value of variable valve at any time, pressure transducer (2) detects the air pressure numerical value of variable valve (1) film chamber at any time, and enter portable computer (8) by signal converter (10), computing machine (8) is with the electric signal of output, the pressure sensing that receives and the static state of displacement sensing signal, dynamic data recording is got off, by end variable valve (1) total travel dynamic response, the linearity, stagnate, change in friction force, stiffness variation, the analysis of parameter such as robust motion and speed, draw the actual performance and the behavior parameter of variable valve (1) and annex thereof, this parameter and theoretical parameter or initial parameter can be obtained a result by computing machine (8) intellectual analysis diagnostic software, and demonstrate the result who detects diagnosis.
Signal converter (10) also can connect the signal output part of other field instrument, as flow signal, pressure signal and temperature signal etc., and forms global function variable valve intelligent checking system with analyser.Signal converter (10) also can upper and lower two the air chamber pressure sensor input signal ends of joint detection air-cylinder type variable valve, and form variable valve performance fault intelligent detection and analysis instrument with analyser.Portable computer (8) and signal converter (10), stop valve (3), pressure transducer (2), can form overall structure form, also can be random combination.
