Plug gauges are generally used for valve inner diameter inspection. Plug gauges usually refer to needle gauges, which are suitable for measuring apertures, hole spacings, internal threads, etc. in mechanical and electronic processing.

[0003] Existing valve inner diameter measurements are mostly performed manually by inspectors, which requires high professionalism of the inspectors. During the inspection, the valve or plug gauge may shake due to the inspectors' unstable hands, which will affect the inspection accuracy. Utility Model Content

Reset springs are provided on the outer surfaces of the two telescopic rods. The valve to be inspected is placed between the two valve clamps. The reset spring pushes the top of the telescopic rod to apply thrust to the valve clamp, so that the two valve clamps clamp the valve, and the valve will not shake during the inner diameter detection.

[0008] Preferably, one end of the two sliding rods extends into the interior of the detection support, and the other end of the two sliding rods extends into the interior of the limiter. Fixed frames are provided at both ends of the two sliding rods, and two limit columns are penetrated through the top of the two fixed frames, so that the two sliding rods can perform linear movement up and down, which is convenient for adjusting the height of the valve to be inspected.

[0009] Preferably, an electric push rod is provided at the top of the fixing frame between the two limit columns, and the electric push rod drives the fixing frame to perform linear movement up and down to achieve the effect of adjusting the height of the valve to be inspected, so that different models of valves can use the equipment for inner diameter detection.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The valve internal diameter detection equipment uses a movable valve support plate. When in use, a plug gauge of corresponding size is installed on the front end of the detection support. First, the through end smooth surface of the plug gauge is extended out of the front end of the detection support. Then, the valve to be inspected is placed between the two valve clamps. The reset spring pushes the top of the telescopic rod to apply thrust to the valve clamp, so that the two valve clamps clamp the valve. The electric push rod is started to drive the fixed frame to move up and down linearly, and the height of the valve support plate is adjusted so that the valve can dock with the plug gauge. Then, the valve support plate is pushed to move linearly on the outside of the slide rod to move the valve toward the plug gauge. The end of the valve to be inspected that needs to detect the inner diameter moves to contact the through end smooth surface. If the through end smooth surface can be inserted into the valve, the next step of detection can be carried out. The plug gauge is turned over so that the stop end smooth surface extends out of the front end of the detection support. If the stop end smooth surface cannot be inserted into the valve, it means that the valve inner diameter is qualified, so that the valve can be smoothly linearly moved during detection, and the valve shaking caused by the hand shaking of the detection personnel will not affect the detection result, and the smooth surface of the plug gauge can be prevented from being scratched and damaged due to the hand shaking of the detection personnel during use.
