Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figure 1-2, a kind of output torque test device 9 of actuator switching mechanism, in frame 4, including
The screw rod 1 of step structure, thrust upper plate 2, thrust lower plate 3, support bar 5, nut 6, wherein, the thrust upper plate 2 and thrust
Lower plate 3 is oppositely arranged and is connected by support bar 5, and nut 6, the screw rod 1 are provided between thrust upper plate 2 and thrust lower plate 3
It is threadedly coupled through thrust upper plate 2 with the circular hole at the center of thrust lower plate 3 with nut 6, the nut 6 passes through pilot hole and support bar
5 are slidably connected, and two disk springs 7 are installed on the screw rod 1, and two disk springs 7 are arranged on the end difference of screw rod 1, and
It is in contact respectively with the thrust upper plate 2 with the medial surface of thrust lower plate 3, the two ends of the screw rod 1 and the upper head plate of frame 4
Rotate and be connected with bottom plate.
Wherein, side is provided with swing arm 8 on the lower surface of the thrust upper plate 2, and test sensor is arranged on testing stand
In frame 4, during the valve actuator operating being connected with screw rod 1, the motion to the left or to the right of swing arm 8 can be driven, so as to oppress test
Sensor contact, torque value is read by the display being connected with test sensor.
During work, valve actuator (not shown) screw rod 1 is connected, and drives screw rod 1 to rotate, and screw rod 1 does rotation fortune
It is dynamic, by screw thread by the convert rotational motion of screw rod 1 into axial movement of the nut 6 along support bar 5, when the top of nut 6 to dish-shaped bullet
During spring 7, nut 6 continues the compressing disk spring 7 that axially moves, and disk spring is deformed upon.When butterfly spring is deformed upon,
Output torque test device 9 is set to be rotated as an entirety in frame 4, and then the output of the force transducer of swing arm 8 is turned round
Square.
Fig. 3, which is shown, is not provided with the schematic diagram that the load value of disk spring amount test device changes with the testing time, can
Load value moment reaches peak value when seeing no disk spring, and impact is big, and noise is big；Disk spring is set to measure trial assembly shown in Fig. 4
The schematic diagram that the load value put is changed over time；Make it can be seen that producing deformation after increase butterfly spring and producing buffering to swing arm extrusion pressure
With, it is to avoid product is because stress is excessively fierce and damages and is more nearly real working condition；Reduced during compared to relatively former no disk spring
Noise, it is more environmentally-friendly.
Due to valve actuator, required torque gradually increases when opening and closing, and sets disk spring to serve mould
Intend the effect for the operating mode that this kind of torque gradually increases.
Design of the present utility model meets debugging and the requirement of trial operation by the application to disc spring, makes the quality of product
Further it is protected.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
