Description

Technical Field

[0001] This utility model relates to the field of testing devices, specifically a device for detecting the radial symmetry of a butterfly valve plate. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve where the closing element is a disc that rotates around the valve shaft to open and close. It primarily functions as a shut-off and throttling device in pipelines. During valve manufacturing, various testing procedures are involved to ensure the valve's quality. After the butterfly valve plate is machined, its symmetry needs to be checked, including the radial symmetry. Traditional testing methods involve manually using a dial indicator to check both sides of the valve plate. However, manual testing inevitably introduces errors, leading to inaccurate results. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) A support frame is installed inside the mounting cavity. After the stepper motor at the top of the support frame rotates, it drives the lead screw at the output end to rotate. The rotation of the lead screw drives the lifting block connected to the surface thread to rotate. A mounting seat is installed on the surface of the lifting block. The mounting seat slides on the guide rail surface on both sides of the support frame surface through the back slider, so that the lifting block moves up and down along the lead screw when the lead screw rotates. The lifting block drives the optical measuring instrument on the surface of the mounting seat to measure the butterfly valve plate, so that the radial symmetry of the butterfly valve plate is detected, and the manual detection method is driven to improve the detection accuracy.

[0015] (2) After placing the butterfly valve plate on the surface of the mounting plate, press down the locking handle on the top of the mounting plate. The locking handle drives the push rod to slide inside the guide sleeve through the connecting rod. The push rod drives the fixed plug rod installed at the bottom to pass through the top of the butterfly valve plate, so that the butterfly valve plate is fixed on the surface of the mounting plate. At the same time, the butterfly valve plate can be rotated and adjusted relative to the push rod, which makes it convenient to rotate and adjust the butterfly valve plate and improve the detection accuracy.

[0024] In practical use: A support frame 41 is installed inside the mounting cavity 3. After the stepper motor 43 on the top of the support frame 41 rotates, it drives the lead screw 42 at the output end to rotate. The rotation of the lead screw 42 drives the lifting block 44 with the surface threaded connection to rotate. A mounting seat 45 is installed on the surface of the lifting block 44. The mounting seat 45 slides on the guide rail 12 on both sides of the surface of the support frame 41 through the back slider 13, so that when the lead screw 42 rotates, the lifting block 44 moves up and down along the lead screw 42. The lifting block 44 drives the optical measuring instrument 46 on the surface of the mounting seat 45 to measure the butterfly valve plate 5, so as to detect the radial symmetry of the butterfly valve plate 5, and drive the manual detection method to improve the detection accuracy. The limit blocks 14 at both ends of the guide rail 12 limit the sliding range of the slider 13.

[0025] Please see Figure 1 , Figure 3 The fixed assembly 6 includes a mounting plate 61 on the surface of the workbench 1, a mounting plate 62 fixedly mounted on the surface of the mounting bracket 2, a locking handle 63 hinged to the top of the mounting plate 62, a connecting rod 64 hinged to the middle of the locking handle 63, a guide sleeve 65 mounted on the bottom of the surface of the mounting plate 62, a push rod 66 slidably mounted inside the guide sleeve 65, one end of the connecting rod 64 hinged to the top of the push rod 66, a fixed insert rod 67 rotatably mounted on the bottom of the push rod 66, the bottom of the butterfly valve plate 5 is placed on the surface of the mounting plate 61, and the fixed insert rod 67 is inserted through the top of the butterfly valve plate 5.

[0026] In practical use: After placing the butterfly valve plate 5 on the surface of the mounting plate 61, press down on the locking handle 63 at the top of the mounting plate 62. The locking handle 63 drives the push rod 66 to slide inside the guide sleeve 65 through the connecting rod 64.

The stepper motor 43, the optical measuring instrument 46 and the servo motor 8 are all electrically connected to the control panel 16. The control panel 16 is electrically connected to an external power supply.

[0032] In practical use: When the control panel 16 is connected to the external power supply, the stepper motor 43, the optical measuring instrument 46 and the servo motor 8 are powered on and controlled to run. When the control panel 16 is disconnected from the external power supply, the equipment stops running.

[0033] A support frame 41 is installed inside the mounting cavity 3. After the stepper motor 43 on the top of the support frame 41 rotates, it drives the lead screw 42 at the output end to rotate. The rotation of the lead screw 42 drives the lifting block 44 with a threaded connection to rotate. A mounting seat 45 is installed on the surface of the lifting block 44. The mounting seat 45 slides on the guide rails 12 on both sides of the surface of the support frame 41 through the back slider 13, so that when the lead screw 42 rotates, the lifting block 44 moves up and down along the lead screw 42.
