The beneficial effects of the utility model are that: structural design is reasonable, converts rotary power to push -pull effort, carries out the push -pull effort loading through valve electric actuator, has satisfied different model electric actuator's test requirement, easy operation, and the test is accurate.
Description
Technical field
It is test bed that the utility model relates to a kind of electric device for valve push and draw force.
Background technology
Valve is the engineering goods bearing interior pressure, thus must have enough strength and stiffness, does not break or produce distortion to ensure Long-Time Service.Work power of closing and open and close moment and refer to valve opening or close the acting force or moment that must apply.The push and draw force of electric device for valve is the important performance indexes embodying valve level.The most of relevant criterion according to country of valve detection devices all at present shows its proof strength and sealing property with tensimeter, and this simple test method can not reflect the problems that a kind of valve exists in design with processing completely.
Show according to domestic industry survey and sci-tech novelty-search, pushing away for valve, tensile test, test and research, domesticly still belong to blank field at present, nobody did this work, both without the testing apparatus of corresponding relation of display valve opening position and torque value, also do not push away at use Site Detection valve, the equipment of pulling force, push away due to the keying of valve under actual condition cannot be understood, the corresponding relation of value of thrust and this value and valve opening, to the design of valve, manufacturing process, use brings blindness, seriously constrain technical progress and the increased quality of valve products, the request for utilization of product can not be met, in addition, for want of moment of torsion real data, so often go wrong in drive unit Matching and selection yet, is not often that moment of torsion selects surplus, causes waste, is exactly that moment of torsion is selected not enough, cannot drives.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of easy and simple to handle, tests accurately that electric device for valve push and draw force is test bed,
The utility model is realized by following measures:
A kind of electric device for valve push and draw force of the present utility model is test bed, comprise base, holder is provided with in the middle part of described base, described holder center has been threaded screw rod, and screw rod laterally runs through holder, and described screw rod one end is connected with power input shaft, described power input shaft end is provided with electric device for valve interface, the screw rod other end is connected with push-and-pull force rod, and described push-and-pull force rod is provided with push-pull effort sensor, and described push-pull effort sensor signal is connected with controller.
Above-mentioned push-and-pull force rod end is provided with back up pad, and push-and-pull force rod end and back up pad are rotationally connected, and is provided with two support bars between back up pad and holder, and two support bars are set in parallel in push-and-pull force rod both sides.
Be connected by shaft coupling between above-mentioned screw rod with push-and-pull force rod.
The beneficial effects of the utility model are: reasonable in design, convert rotary power to push-pull effort, carry out push-pull effort loading by electric device for valve, meet the test request of different model electric device, simple to operate, and test accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 base, 2 holders, 3 power input shafts, 4 electric device for valve interfaces, 5 screw rods, 6 shaft couplings, 7 push-and-pull force rods, 8 support bars, 9 push-pull effort sensors, 10 back up pads.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
As shown in Figure 1, a kind of electric device for valve push and draw force of the present utility model is test bed, comprise base 1, holder 2 is provided with in the middle part of base 1, holder 2 center has been threaded screw rod 5, and screw rod 5 laterally runs through holder 2, screw rod 5 one end is connected with power input shaft 3, power input shaft 3 end is provided with electric device for valve interface 4, screw rod 5 other end is connected with push-and-pull force rod 7, push-and-pull force rod 7 is provided with push-pull effort sensor 9, push-pull effort sensor 9 signal is connected with controller.Push-and-pull force rod 7 end is provided with back up pad 10, and push-and-pull force rod 7 end and back up pad 10 are rotationally connected, two support bars 8 are provided with between back up pad 10 and holder 2, two support bars 8 are set in parallel in push-and-pull force rod 7 both sides, holder 2 both sides are made to be subject to holdback force, prevent holder 2 from rocking, ensure to operate steadily.Be connected by shaft coupling 6 between screw rod 5 with push-and-pull force rod 7.
During use, electric device for valve to be measured is arranged on electric device for valve interface 4, valve is transferred to certain aperture, power input shaft 3 rotates, screw rod 5 is driven to rotate, because screw rod 5 and holder 2 form screw screw body, screw rod 5 rotation in holder 2 can convert transverse shifting to, and then produces thrust or pulling force to push-and-pull force rod 7.Push-pull effort sensor 9 detects that thrust or pulling force signal send controller to, and the aperture of controller to thrust or pulling force signal and valve is comprehensively analyzed, and finally draws testing result.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
