Abstract
The utility model provides a novel electric head moment prover of a valve. A sensor is a pipe-shaped torque sensor; each of both ends of the pipe is provided with a flange. When the utility model is used, the sensor can be directly arranged between the valve and a joint flange of an electric head, and is communicated with a corresponding secondary meter circuit through connectors, and then is communicated with a power supply, and can prove the moment of the electric head. The prover is portable and flexible, is in particular applicable for proof of the valve at the loading bay and setting the output torque of the electric head for users of electric valves, and can be used for detection of operating characteristics of valves by valve manufacturers.
Description
Affiliated technical field
The purpose of this utility model provides a kind of electric valve head moment tester.
Background technique
Electric valve is widely used in the factories and miness equipment such as power station, petrochemical industry, medicine food.The open and close of electric valve come executable operations by the electric valve head.The moment of this operation, promptly the output torque of electrical header must conscientiously be adjusted and set.Moment is excessive, may cause the damage of valve or electrical header part; If moment is too small, then can not guarantee the leakproofness of valve closing, or valve can't be opened because of opening the moment deficiency.So each electrical header all needs regularly to carry out the setting and the verification of output torque.For the intelligent electric head, though itself has moment display device, after preventing to use a period of time the data drift takes place, also need periodic calibrating.
Present employed moment check table is normally directly measured the output torque of electrical header output shaft.Mainly form by transmission shaft, torque sensor, braking device and matching instrument etc.Torque sensor is fixed on the transmission shaft of check table, links to each other with the output shaft of electrical header, and together rotates with axle.Adjust the size of moment by braking device.The torque signals that sensor records need could be sent on the non-rotary secondary meter (display instrument or recorder etc.) by lead through the special switching mechanism of a cover.In use there is following defective in this check table:
1. complex structure and volume are bigger, are not easy to move.Only being adapted at electrical header manufacturing firm uses.It can not satisfy the needs of valve user verification electrical header moment.
2. the working condition of this check table is different with the actual conditions of electric valve.The change procedure of electrical header actual output torque when therefore, this check table can not reflect valve working.
Summary of the invention:
The utility model provides a kind of novel moment tester for the valve user.It need not special test-bed, can use the scene at valve, is directly installed between valve and the electrical header, and the output torque of electrical header is carried out verification and adjustment.Thereby can satisfy the needs of the output torque of vast valve user verification and adjustment electric valve head.
The technical solution of the utility model is: the moment tester is made up of torque sensor and corresponding secondary meter, and its sensor is a kind of tubular torque sensor, and respectively is furnished with a flange at the two ends of pipe.Like this, it just can be mounted and fixed between the adpting flange of electrical header and valve.Because sensor installation, therefore the position of having raised electrical header need install a connecting rod additional in the pipe endoporus of sensor, to keep being in transmission connection of electrical header output shaft and valve.When electrical header drove the valve running, sensor did not rotate, but realized detecting (the output torque numerical value of this reactive torque and electrical header is identical and direction is opposite) by the method for measuring the suffered reactive torque of electrical header housing.
Useful benefit of the present utility model is: compare with existing check table since tester main body---torque sensor does not rotate, so can economize the switching mechanism of omitting torque signals; Because it can directly be installed and be fixed between valve and the electrical header, more can economize a series of auxiliary devices such as the transmission shaft that omits existing check table, braking device, stand again.It is simply light that whole tester becomes, and the valve user can use it in the valve erecting bed.
The utility model not only can detect the actual output torque of electrical header, also can measure the change procedure of moment in the valve operation simultaneously, obtains the operating characteristics of valve.
Description of drawings
Accompanying drawing is the half-sectional view of moment tester.Part is respectively among the figure: 1 upper flange, 2 torque sensors, 3 protecting jackets, 4 lower flanges, 5 lead terminals.
Embodiment
During work, the upper flange of this tester (1) is connected with the lower flange of electrical header, and lower flange (4) is connected with the flange at valve rack top.In center hole, use the connecting rod that is complementary with electrical header that the output shaft of electrical header and the driving port of valve rod are coupled together.And, connect power supply again by the circuit connection of lead terminal (5) with sensor and secondary meter, and just can start electrical header, on secondary meter, read torque value.According to the torque value that shows, progressively adjust the moment setting device, make moment reach setting value and also lock.At last, take off the moment tester, electrical header is reinstalled on the valve, the work of moment verification is just accused and is finished.
Claims (3)
1. an electric valve head moment tester is made up of torque sensor and corresponding secondary meter, it is characterized in that sensor is a kind of tubular torque sensor, and respectively is furnished with a flange at the two ends of pipe.
2. electric valve head moment tester according to claim 1 is characterized in that the connecting flange of the electrical header of the specification of upper flange of sensor and same specification is complementary, and lower flange then is complementary with the upper flanges of the valve rack of same specification.
3. electric valve head moment tester according to claim 1 is characterized in that the pipe endoporus of tubular sensor should be able to be by the connecting rod of electrical header output shaft.
