[0028] V-shaped plate 3 is connected with the top of base 1 through support frame, and the top of base 1 is provided with measuring rod 2 on both sides, and the top of base 1 is provided with scale groove 9 on both sides.

[0029] Two measuring rods 2 are connected with the top of base 1 through bidirectional synchronous moving mechanism, and the center of both sides of V-shaped plate 3 is provided with side groove 6, and V-shaped plate 3 is provided with pressing rod 7 in the inside, and the both ends of pressing rod 7 are slidably connected with the inside of two side grooves 6, and the top of V-shaped plate 3 is provided with vertical lifting mechanism connected with pressing rod 7.

[0030] Firstly, the valve to be measured is placed inside the V-shaped plate 3. Due to the V-shaped design of the V-shaped plate 3, it can well adapt to and accommodate valves of different sizes, ensuring that the valve can be placed in a relatively central position. Then, the pressure rod 7 is driven to slide inside the side groove 6 on both sides of the V-shaped plate 3 by the vertical lifting mechanism. The pressure rod 7 gradually descends until its bottom is in close contact with the top of the valve, thereby clamping and fixing the valve. This step effectively solves the problem of insufficient stability of the valve in the traditional device, ensuring that the valve will not shift during the measurement process due to external force or its own weight.

[0031] After the valve is stably clamped, the operator drives the two measuring rods 2 on the top of the base 1 to move synchronously by the bidirectional synchronous moving mechanism. During the movement of the measuring rod 2, it will be adjusted according to the actual size of the valve until its end is in contact with the two sides or specific measurement points of the valve. At this time, the operator can quickly read the valve size indicated by the measuring rod 2 through the scale groove 9 opened on the top of the base 1. The design of the scale groove 9 makes the reading of the measurement result more intuitive and accurate, greatly improving the measurement efficiency.

[0032] Embodiment Two

[0033] Please refer to Figures 1-5 As shown in the figure, the size measuring device for valve plate of the valve of the embodiment, the two inner walls of the V-shaped plate 3 are connected with the protective pad 4, the protective pad 4 is made of rubber material, specifically, when the valve is placed inside the V-shaped plate 3, the protective pad 4 will contact with the outer wall of the valve. Since the protective pad 4 is made of rubber material, it has good elasticity and wear resistance, so it can effectively avoid the scratches or wear that may be caused when the valve directly contacts with the V-shaped plate 3. Achieve the effect of protecting the surface of the valve from damage, improving the safety of the measuring device and the service life of the valve.

[0034] The vertical lifting structure includes a push cylinder 8 connected with the top of the V-shaped plate 3 through the mounting bracket 5, and the output end of the push cylinder 8 is connected with the top of the pressure rod 7. Specifically, when the valve needs to be clamped, the push cylinder 8 will start and drive the pressure rod 7 to slide and descend inside the side groove 6 until the pressure rod 7 is in close contact with the top of the valve. Achieve the effect of quickly and accurately clamping the valve, improving the stability of the valve during the measurement process, and ensuring the accuracy of the measurement result.

[0035] Embodiment Three

[0036] Please refer to Figures 1-5As shown, the size measuring device for valve valve plate of the embodiment is provided with a sliding groove 10 on each side of the top of the base 1, and the bottom of the measuring rod 2 is fixedly connected with a sliding rod 13 matched with the sliding groove 10. Specifically, when the bidirectional synchronous moving mechanism drives the measuring rod 2 to move, the sliding rod 13 will slide in the sliding groove 10 to provide stable guidance and support for the measuring rod 2. The stability and accuracy of the measuring rod 2 during movement are ensured, and the effect of improving the measurement accuracy is achieved by avoiding the deviation or shaking of the measuring rod 2.

[0037] The bottom of one side of the measuring rod 2 is fixedly connected with a pointing rod 12, and one end of the pointing rod 12 extends to the top position of the scale groove 9. Specifically, when the measuring rod 2 is moved into position and contacts the two sides of the valve or a specific measurement point, the pointing rod 12 will point to the corresponding position in the scale groove 9, so that the operator can more intuitively read the measurement result. The reading efficiency of the measurement result is improved, human error is reduced, and the measurement process is more convenient and fast.

[0038] The bidirectional synchronous moving mechanism includes a driving motor 11 installed on one side of the base 1 and a bidirectional screw rod 14 arranged in the base 1. The two ends of the bidirectional screw rod 14 are threadedly penetrated through the adjacent sliding rods 13. The output shaft of the driving motor 11 is in transmission connection with the end of the bidirectional screw rod 14. Specifically, when the measuring rod 2 needs to be moved, the driving motor 11 is started to drive the bidirectional screw rod 14 to rotate, thereby driving the two sliding rods 13 to move synchronously in the sliding grooves 10, and the synchronous mutual movement of the measuring rods 2 is realized. The two measuring rods 2 can be moved synchronously and accurately, the measurement efficiency and accuracy are improved, and the effect of avoiding the out-of-sync or deviation in the measurement process is achieved.

[0039] The scheme has the following working process:

[0040] The device includes a base 1 and a V-shaped plate 3 connected to the top center of the base 1 through a support frame to ensure stable support. The top of the base 1 is provided with a measuring rod 2 on each side for measuring the size of the valve, and the top of the base 1 is provided with a scale groove 9 on each side to facilitate reading the measurement result.

[0041] Firstly, the valve to be measured is placed in the V-shaped plate 3. The V-shaped design of the V-shaped plate 3 can well adapt to and accommodate valves of different sizes, ensuring that the valve can be placed in a relatively central position. In order to further protect the surface of the valve from being damaged, the two inner walls of the V-shaped plate 3 are connected with protective pads 4 made of rubber material, which has good elasticity and wear resistance, effectively avoiding scratches or wear when the valve directly contacts the V-shaped plate 3.

[0042] Then, the pressure rod 7 is driven to slide in the side groove 6 on both sides of the V-shaped plate 3 through the vertical lifting mechanism. The vertical lifting mechanism comprises a push cylinder 8 connected with the top of the V-shaped plate 3 through the mounting frame 5, and the output end of the push cylinder 8 is connected with the top of the pressure rod 7. When the valve needs to be clamped, the push cylinder 8 is started and drives the pressure rod 7 to gradually descend until the bottom of the pressure rod 7 is in close contact with the top of the valve, so that the valve is clamped and fixed. This step effectively solves the problem of insufficient stability of the valve in the traditional device, ensures that the valve will not be displaced due to external force or its own weight during the measurement process, improves the stability of the valve during the measurement process, and ensures the accuracy of the measurement result.

[0043] After the valve is stably clamped, the two measuring rods 2 on the top of the base 1 are synchronously moved relative to each other by the bidirectional synchronous moving mechanism. The bidirectional synchronous moving mechanism comprises a driving motor 11 mounted on one side of the base 1 and a bidirectional screw rod 14 arranged in the base 1. The two ends of the bidirectional screw rod 14 are threaded through the adjacent slide rods 13, and the output shaft of the driving motor 11 is in transmission connection with the ends of the bidirectional screw rod 14. When the measuring rods 2 need to be moved, the driving motor 11 is started and drives the bidirectional screw rod 14 to rotate, so that the two slide rods 13 are synchronously moved in the sliding groove 10 on the top of the base 1, thereby realizing the synchronous movement of the measuring rods 2 relative to each other. During the movement of the measuring rods 2, the actual size of the valve is adjusted until the ends of the measuring rods 2 are in contact with the two sides of the valve or the specific measurement points.

[0044] In order to more intuitively read the measurement result, a pointing rod 12 is fixedly connected to one side of the bottom of the measuring rod 2, and one end of the pointing rod 12 extends to the top position of the scale groove 9. When the measuring rod 2 is moved to the position and is in contact with the two sides of the valve or the specific measurement points, the pointing rod 12 points to the corresponding position in the scale groove 9, so that the operator can quickly and accurately read the valve size indicated by the measuring rod 2. The design of the scale groove 9 makes the reading of the measurement result more intuitive and accurate, greatly improves the measurement efficiency, and reduces the human error.
