Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a device for detecting the flatness of valve connections. Background Technology

[0002] A valve connection smoothness monitoring device is a specialized instrument used to detect the smoothness of the connection surfaces between valves and pipelines. In industrial piping systems, the installation quality of valves directly affects the system's sealing performance and service life. Uneven valve connection surfaces can lead to media leakage, pressure loss, and even equipment damage. Therefore, accurate detection of valve connection smoothness is crucial.

[0003] For example, a common valve connection flatness monitoring device works by using a movable measuring head to measure the surface height difference at the valve connection through mechanical contact.

[0004] Although this device can provide certain measurement results, because the measuring head is in direct contact with the valve, it is easily affected by factors such as surface roughness and foreign objects, which can cause the measuring head to wobble and thus produce measurement errors. Utility Model Content

[0005] In view of this, the present invention provides a valve connection flatness detection device. The present invention can stabilize the position of the detection plate and avoid errors caused by shaking.

[0006] To solve the above-mentioned technical problems, this utility model provides a valve connection flatness detection device, including a connecting cylinder and a detection component. The detection component includes two symmetrically distributed detection plates slidably connected to the middle of the connecting cylinder. Two symmetrically distributed clamping plates are fixedly connected to the inner wall of the middle of the connecting cylinder. The middle of each detection plate is in contact with the top of the clamping plate. A fixing plate is fixedly connected to the top of the connecting cylinder. Multiple springs are fixedly connected to the bottom of the fixing plate. The springs are vertically distributed with the detection plates, which can stabilize the position of the detection plates and facilitate the detection of the height difference of the detection plates, avoiding errors caused by shaking.

[0007] Multiple guide posts are slidably connected in the middle of the fixed plate, and the positions of the guide posts correspond one-to-one with the positions of the springs; that is, to ensure the vertical state of the springs during the compression process and to prevent lateral displacement.

[0008] Each test plate has a pad on top, and the top of each pad is fixedly connected to the bottom of the adjacent guide column; this ensures uniform pressure distribution and avoids errors caused by local pressure concentration.

[0009] The tops of the guide columns located above the same detection plate are fixedly connected to the same connecting plate; this ensures that the guide columns move synchronously, thereby maintaining the stability and verticality of the detection plate.

[0010] The bottom of the detection plate is an outer arc surface, with the convex side of the outer arc facing downwards; this ensures the specificity and accuracy of the measurement.

[0011] The bottom of the detection plate is provided with multiple arrayed anti-slip grooves to prevent the detection plate from slipping during the detection process.

[0012] Observation ports are provided on both sides of the connecting cylinder; this improves detection efficiency and reduces operational errors.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. It can stabilize the position of the detection plate, making it convenient to detect the height difference of the detection plate and avoiding errors caused by shaking.

[0015] 2. It can enhance the friction between the detection plate and the valve connection, preventing the detection plate from slipping during the detection process. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4 As shown: This embodiment provides a valve connection flatness detection device, including a connecting cylinder 100 and a detection component 200. The detection component 200 includes two symmetrically distributed detection plates 201 slidably connected to the middle of the connecting cylinder 100. Two symmetrically distributed clamping plates 202 are fixedly connected to the inner wall of the middle part of the connecting cylinder 100. The middle part of the detection plates 201 is in contact with the top of the clamping plates 202. A fixing plate 203 is fixedly connected to the top of the connecting cylinder 100. A plurality of springs 204 are fixedly connected to the bottom of the fixing plate 203. The springs 204 are distributed vertically and vertically corresponding to the positions of the detection plates 201.

[0025] During testing, the connecting cylinder 100 is placed on top of the testing area and then pressed down so that the bottoms of the two testing plates 201 are respectively in contact with the two sides of the valve connection. Then, the pressure is continued to press down so that the testing plates 201 are under pressure. If one side of the valve connection is higher than the other side, it will push up the testing plate 201 on top of it, making the heights of the two testing plates 201 inconsistent. The height difference of the valve connection can be measured by measuring the height difference of the two in contact testing plates 201, and then it can be corrected.

[0026] When the detection plate 201 is under pressure for testing, it will push up the top spring 204. After the spring 204 is compressed, it will continuously apply pressure to the top of the detection plate 201, thereby preventing the detection plate 201 from shaking up and down during testing. By fixing the position of the top of the detection plate 201 with the spring 204, the position of the detection plate 201 can be stabilized, which makes it convenient to detect the height difference of the detection plate 201 and avoids errors caused by shaking.

[0027] Guide column 205 Figure 1 , 2 As shown,

[0028] Multiple guide posts 205 are slidably connected to the middle of the fixed plate 203. The positions of the guide posts 205 correspond one-to-one with the positions of the springs 204. The diameter of each guide post 205 is smaller than the diameter of the spring 204.

[0029] The guide post 205 guides the spring 204, ensuring it remains vertical during compression and preventing lateral shift. This results in more uniform and stable pressure from the spring 204 on the detection plate 201, thus improving detection accuracy.

[0030] 206 pad Figure 1 , 2 As shown in Figure 3,

[0031] Each detection plate 201 has a pad 206 placed on its top, and the top of each pad 206 is fixedly connected to the bottom of the adjacent guide post 205.

[0032] The shape of the pad 206 matches the shape of the top of the detection plate 201, ensuring uniform pressure distribution and avoiding errors caused by localized pressure concentration. This uniform pressure distribution helps to more accurately measure the height difference at the valve connection, thereby improving the accuracy of the calibration.

[0033] Connector 207 Figure 1 , 2 As shown,

[0034] The top of the guide post 205 located above the same detection plate 201 is fixedly connected to the same connecting plate 207;

[0035] The connecting plate 207 can make the guide columns 205 located above the same detection plate 201 move synchronously. When the detection plate 201 is lifted by the uneven surface at the valve connection, the connecting plate 207 ensures that the guide columns 205 move synchronously, preventing the detection plate 201 from tilting or shaking due to asynchronous movement of the guide columns 205, thereby maintaining the stability and verticality of the detection plate 201.

[0036] Detection board 201 Figure 1 , 2 As shown in Figure 4,

[0037] The bottom of the detection plate 201 is an outer arc surface, with the convex side of the outer arc surface facing downwards;

[0038] The valve connection is usually circular. The arc-shaped contact surface allows for more precise positioning when it aligns with the valve connection. The two circles aligning together allow the detection plate 201 to measure only a specific point on the valve, rather than measuring an entire area.

[0039] Anti-slip groove 101 Figure 1 , 2 As shown in Figure 4,

[0040] The bottom of the detection plate 201 is provided with multiple anti-slip grooves 101 arranged in an axial array around the bottom of the detection plate 201;

[0041] The anti-slip groove 101 can enhance the friction between the detection plate 201 and the valve connection, and prevent the detection plate 201 from slipping during the detection process.

[0042] Observation port 102 Figure 1 , 2 As shown in Figure 3,

[0043] The connecting cylinder 100 has observation ports 102 on both sides, and the middle of the observation port 102 is at the same horizontal line as the top of the detection plate 201.

[0044] When the detection plate 201 is pressed down and aligned with the valve connection, the operator can quickly determine whether there is a height difference between the two detection plates 201 through the observation port 102. If a height difference exists, it indicates that there is unevenness at the valve connection, which needs to be corrected. This intuitive measurement method not only improves detection efficiency but also reduces operational errors.

[0045] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
