Description
Technical field
The utility model relates to the torsion-testing machine that a kind of valve is used, and particularly a kind ofly can substitute traditional arm of force type torque measuring method, fast the output torque of valve turbine box is measured, and is demonstrated the valve worm gear case torsion-testing machine of measurement result simultaneously.
Background technology
The output torque of traditional valve worm gear case generally adopts the method for arm of force weight measurement moment of torsion, promptly in the axis hole of turbine box output shaft, inserts coupling shaft, to measuring the coupling shaft application of force that moment of torsion is used, measures the turbine box output torque through lever.This measuring method detection speed is slow, and the replacing counterweight that need not stop also need calculate after the test, and human factor is bigger, and measurement result is had very big influence.Valve to detect more than the DN600 is an example, and the turbine box output torque value of its use is big, and the lever that needs is about more than 3 meters.Therefore, this measuring method exists and takes up room greatly, and complex operation is measured inaccurately, can not directly draw the disadvantage of measurement result.In addition, this quality through the arm of force and counterweight calculates result's method, because inefficiency so can only inspect by random samples in batches, can not carry out moment of torsion to every deck valve door turbine box and detect.
The utility model content
The purpose of the utility model provides a kind of valve worm gear case torsion-testing machine, and it is big that it has solved taking up room of traditional arm of force weight measurement torque method existence, complex operation; Disadvantages such as inefficiency, it is reasonable in design, compact conformation, simple to operate; It is little to take up room; Measure fast, accurately, and direct display result, be applicable to that every deck valve door turbine box is carried out moment of torsion to be detected.
The technical scheme that the utility model adopted is: this valve worm gear case torsion-testing machine comprises support, is assembled in the joint flange on the support and measures the coupling shaft that moment of torsion is used; It is characterized in that: an end that passes the joint flange through hole of said coupling shaft inserts and is fixed in the axis hole of the turbine box output shaft on the joint flange; The top of the static torque measurement axis of the other end of coupling shaft and torque measurement mechanism fits together through axle sleeve, and the bottom and the mounting flange on the support that have the static torque measurement axis of sensor link together.
Sensor on the static torque measurement axis of said torque measurement mechanism is connected with data display screen on being fixed on support through transmission line.
Advantage and the good effect that the utlity model has are: because the static torque measurement axis that has sensor of the torque measurement mechanism of the utility model fits together through axle sleeve and coupling shaft; The axis hole of the worm gear case output shaft of coupling shaft and valve worm gear case torque measurement end interconnects; So it is reasonable in design; Compact conformation, simple to operate, it is little to take up room, and can realize the quick measurement of turbine box moment of torsion.Compare with the method for traditional arm of force weight measurement moment of torsion, it has measures fast, accurately, and directly shows the advantage
of measurement result.It is big that it has solved taking up room of traditional arm of force weight measurement torque method existence, complex operation, and disadvantages such as inefficiency, therefore, the utility model is specially adapted to that every deck valve door turbine box is carried out moment of torsion and detects.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is the side view of Fig. 1.
Sequence number explanation among the figure: 1 mounting flange, 2 static torque measurement axis, 3 axle sleeves, 4 coupling shafts, 5 joint flanges, 6 data display screens, 7 supports.
Embodiment
Specify the concrete structure of the utility model according to Fig. 1～2.This valve worm gear case torsion-testing machine comprises support 7, be assembled in mounting flange 1, joint flange 5 on the support 7, measure parts such as coupling shaft 4 that moment of torsion uses and torque measurement mechanism.Wherein torque measurement mechanism mainly comprises the static torque measurement axis 2 that has sensor, measures parts such as coupling shaft 4 that moment of torsion uses and data display screen 6.Wherein mounting flange 1 is installed in support 7 bottoms, and the bottom of the static torque measurement axis 2 of torque measurement mechanism links together through key and mounting flange 1.Joint flange 5 is fixedly connected with support 7 table tops.The top of static torque measurement axis 2 is fitted together through axle sleeve 3 bottom group with coupling shaft 4, and the through hole that joint flange 5 is passed at the top of coupling shaft 4 is connected with the axis hole of worm gear case output shaft of valve worm gear case (not shown) torque measurement end on being fixed on joint flange 5.Coupling shaft 4 and axle sleeve 3 can be changed coupling shaft 4 easily for key is connected, to realize that the valve turbine box of different size is carried out the detection of moment of torsion.Sensor on the static torque measurement axis 2 is connected with data display screen 6 on being fixed on support 7 through transmission line; After static torque measurement axis 2 is stressed; Just through sensor the static torque signal is transferred on the data display screen 6, on data display screen 6, demonstrates the corresponding torque value.
During detection, through bolt valve worm gear case and joint flange 5 are fixed, the coupling shaft 4 that passes the axis hole of the worm gear case output shaft of the torque measurement end of valve worm gear case and top joint flange 5 through holes links together.Move worm gear case through the dial torque wrench that preestablishes input torque and drive coupling shaft 4 rotations; Static torque measurement axis 2 is under the rotating force effect of coupling shaft 4; Generate the input torque value; Sensor on the static torque measurement axis 2 is given data display screen 6 just through transmission line with the torque value signal conveys, and the torque value that data display screen 6 demonstrates is the output torque of valve worm gear case; When input torque reached capacity, the torque value that data display screen 6 demonstrates was the max. output torque of valve turbine box.Because data display screen 6 adopts digital display type moment of torsion indicator gauges, so can show clearly fast and the output torque value improved detection speed and precision.
