Description

Technical Field

[0001] This utility model relates to the field of valve condition monitoring technology, and in particular to a valve with valve condition monitoring function. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0003] The published patent 202322842233.3 includes a valve body, a valve cover, a valve stem, a valve core, and a handle. Its features include: the valve cover is mounted on the valve body; the valve stem is threaded through the valve cover; the valve core is mounted on the valve stem; the handle is mounted on the valve stem; and a detection device is mounted on the valve cover. The design allows for batch detection of valve opening / closing status from the outside without requiring the valve to be opened to install flow or pressure sensors. The method is simple, using a distance switch and a noise sensor to determine valve opening status from both height and sound perspectives. These sensors are mounted outside the valve body, requiring no waterproofing and are relatively inexpensive. Batch detection is possible, reducing labor time; the combination of these two methods reduces the risk of errors.

[0004] The above structure is mainly designed for valves that open and close from top to bottom. However, many existing valves open and close by rotating an angle. The above monitoring structure cannot monitor the valve opening and closing angle in real time, which reduces the accuracy of the monitoring data.

[0005] Therefore, it is necessary to provide a valve with valve status monitoring function to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a valve with valve status monitoring function, which solves the problem that pressure sensors and noise sensors can only determine the opening and closing status of valves that open and close vertically, but cannot accurately monitor the opening and closing angle of valves that open and close by rotation.

[0007] To solve the above-mentioned technical problems, the valve with valve status monitoring function provided by this utility model includes: a valve body;

[0008] A connecting pipe is fixedly connected to the top of the outer surface of the valve body. A sealing disc is bolted to the top of the connecting pipe. A rotating shaft is rotatably connected to the top of the sealing disc via a sealing structure. A disc is fixedly connected to the bottom of the rotating shaft. A rotating disk is installed at the top of the rotating shaft. A fixing ring is installed near the top of the outer surface of the rotating shaft. A mounting cover is fixedly connected to the outer surface of the fixing ring. A contact ring is fixedly connected to the bottom of the mounting cover at the outer surface. A energizing block is installed on the inner surface of the contact ring. Multiple bases are installed on the top of the mounting cover, and an indicator light is installed on the top of each base.

[0009] A sealing plug is fixedly connected to the bottom of a sealing disc. A support ring is installed on the top of the sealing disc, and an installation ring is installed on the top of the support ring. Multiple contact blocks are installed on the outer surface of the installation ring.

[0010] The sealing structure increases the sealing performance of the connection between the sealing disc and the rotating shaft. The retaining ring is located between the sealing structure and the rotating disc, and it rotates synchronously with the rotating shaft. The positions of the energized block and the contact block correspond to each other. The rotation angle of the disc is generally ninety degrees, so the maximum orientation monitored by the contact block is ninety degrees. The structure on the mounting cover uses homogeneous wire connections, and the sealing plug is inserted into the inside of the connecting tube to increase the sealing performance. The structure on the mounting cover uses low-voltage current, which will not harm the personnel. The angle corresponding to each contact block is ten degrees, and more detailed allocation can be made if needed.

[0011] Preferably, a battery is installed on the top of the inner wall of the mounting cover, and a control frame is installed on the top of the inner wall of the mounting cover.

[0012] The control frame is equipped with a power switch and a controller to control the operation of the equipment inside the mounting enclosure.

[0013] Preferably, both ends of the valve body are fixedly connected to flanges, and one end of each flange is provided with multiple mounting holes.

[0014] Preferably, a fixed base is mounted on the outer surface of the valve body, and a flow rate sensor is mounted on one side of the fixed base;

[0015] The connection between the fixed base and the valve body has been sealed.

[0016] Preferably, a protective cover is installed on the outer surface of the sealing disc, and a pull bolt is fixedly connected to the top of the protective cover;

[0017] The protective cover encloses the structure at the top of the connecting pipe, providing protection and preventing corrosion.

[0018] Preferably, two docking rings are installed inside the valve body, the contact block and the energizing block are both made of copper, and an operation panel is installed on the outer surface of the mounting cover via a mounting plate;

[0019] The mating rings are all semi-circular, and the two mating rings are staggered and make contact with the two ends of the disc near the outer surface, which can increase the sealing effect.

[0020] Compared with related technologies, the valve with valve status monitoring function provided by this utility model has the following beneficial effects:

[0021] This invention provides a valve with valve status monitoring function. To monitor the opening and closing angle of the disc in a butterfly valve in real time, a quarter-circle arc-shaped support ring is installed on the top of the sealing disc. A mounting ring with multiple contact blocks is then installed above the support ring, ensuring that the spacing between each contact block is the same, resulting in a 10-degree angle between every two contact blocks. The mounting cover is then fixed to the outer surface of the rotating shaft using a fixing ring, allowing the mounting cover to rotate synchronously with the shaft. A contact ring with an energized block on its inner surface is installed at the bottom of the mounting cover, with the energized block and the contact block positioned correspondingly. For easy viewing, multiple indicator lights are mounted on the top of the mounting cover via multiple bases, with the number and position of the indicator lights corresponding to the contact blocks. This design, using a simple energized light principle, allows for real-time monitoring of the opening and closing angle of the disc in the valve, increasing the safety of valve operation.

The valve with valve status monitoring function includes: valve body 1;

[0031] A connecting pipe 2 is fixedly connected to the top of the outer surface of the valve body 1. A sealing disc 12 is installed on the top of the connecting pipe 2 by bolts 15. A rotating shaft 10 is rotatably connected to the top of the sealing disc 12 by a sealing structure 11. A disc 14 is fixedly connected to the bottom of the rotating shaft 10. A rotating disk 9 is installed on the top of the rotating shaft 10. A fixing ring 16 is installed on the outer surface of the rotating shaft 10 near the top. A mounting cover 8 is fixedly connected to the outer surface of the fixing ring 16. A contact ring 7 is fixedly connected to the bottom of the mounting cover 8 on the outer surface. An energizing block 26 is installed on the inner surface of the contact ring 7. Multiple bases 17 are installed on the top of the mounting cover 8. An indicator light 18 is installed on the top of each base 17.

[0032] A sealing plug 13 is fixedly connected to the bottom of a sealing disc 12. A support ring 20 is installed on the top of the sealing disc 12. An installation ring 21 is installed on the top of the support ring 20. Multiple contact blocks 22 are installed on the outer surface of the installation ring 21.

[0033] The sealing structure 11 can increase the sealing performance of the connection between the sealing disc 12 and the rotating shaft 10. The fixing ring 16 is located between the sealing structure 11 and the rotating disc 9. The fixing ring 16 will rotate synchronously with the rotating shaft 10. The positions of the energizing block 26 and the contact block 22 are corresponding. The rotation angle of the disc 14 is generally ninety degrees, so the maximum position monitored by the contact block 22 is ninety degrees. The structure on the mounting cover 8 is a homogeneous wire connection. The sealing plug 13 is inserted into the inside of the connecting tube 2 to increase the sealing performance. The structure on the mounting cover 8 uses a low voltage current that will not harm the staff. The angle corresponding to each contact block 22 is ten degrees. If needed, a more detailed allocation can be made. After the energizing block 26 contacts the contact block 22 at the corresponding angle, the indicator light 18 at the corresponding angle can be energized.

[0034] A battery 24 is installed on the top of the inner wall of the mounting cover 8, and a control frame 25 is installed on the top of the inner wall of the mounting cover 8.

[0035] Battery 24 supplies power to the equipment inside the mounting cover 8, and control box 25 is equipped with a power switch and a controller for controlling the operation of the equipment inside the mounting cover 8.

[0036] Both ends of the valve body 1 are fixedly connected to flanges 3, and one end of each flange 3 is provided with multiple mounting holes 4.

[0037] Flange 3 is for easy pipe connection to valve body 1.

[0038] A fixed base 29 is installed on the outer surface of the valve body 1, and a flow rate sensor 27 is installed on one side of the fixed base 29.

[0039] The monitoring end of the flow rate sensor 27 is located inside the valve body 1, and the connection between the fixed base 29 and the valve body 1 is sealed.

[0040] A protective cover 6 is installed on the outer surface of the sealing disc 12, and a pull bolt 5 is fixedly connected to the top of the protective cover 6;

[0041] The protective cover 6 covers the top structure of the connecting pipe 2, which can play a role in protection and corrosion prevention. The protective cover 6 can be made of transparent material.

[0042] The valve body 1 has two docking rings 28 installed inside. The contact block 22 and the energizing block 26 are both made of copper. The outer surface of the mounting cover 8 is equipped with an operation panel 23 via a mounting plate 19.

[0043] The docking rings 28 are all semi-circular. The two docking rings 28 are staggered and make contact with the two ends of the disc plate 14 near the outer surface, which can increase the sealing effect. The operation screen 23 can display the monitoring data.

[0044] The working principle of the valve with valve status monitoring function provided by this utility model is as follows:

[0045] A quarter-circle support ring 20 is placed at the top of the sealing disc 12. A mounting ring 21 with multiple contact blocks 22 is then installed above the support ring 20, ensuring that the spacing between each contact block 22 is the same, allowing for a 10-degree angle between every two contact blocks 22. The mounting cover 8 is then fixed to the outer surface of the rotating shaft 10 using a retaining ring 16, allowing the mounting cover 8 to rotate synchronously with the rotating shaft 10. A contact ring 7 with an inner surface carrying a conductive block 26 is installed at the bottom of the mounting cover 8, ensuring that the conductive block 26 corresponds to the contact block 22. This arrangement is for easy observation by the operator. See, multiple indicator lights 18 are mounted on the top of the mounting cover 8 via multiple bases 17, and the number and position of the indicator lights 18 correspond to the contact blocks 22. In actual use, when the baffle plate 14 is completely closed, the energizing block 26 will contact the outermost contact block 22, thereby forming a current, which will cause the indicator light 18 at the corresponding position to light up. When it is opened or closed to the corresponding angle, the energizing block 26 will separate from the contact block 22 that was originally in contact, and then contact the contact block 22 at the corresponding angle, which will cause the indicator light 18 that displays the corresponding angle to light up, so that the opening and closing angle of the baffle plate 14 in the valve can be accurately monitored.

[0046] Compared with related technologies, the valve with valve status monitoring function provided by this utility model has the following beneficial effects:

[0047] To enable real-time monitoring of the opening angle of the disc 14 in the butterfly valve, a quarter-circle support ring 20 is installed on the top of the sealing disc 12. A mounting ring 21 with multiple contact blocks 22 is then installed above the support ring 20, ensuring that the spacing between each contact block 22 is uniform, resulting in a 10-degree angle between every two contact blocks 22. The mounting cover 8 is then fixed to the outer surface of the rotating shaft 10 using a fixing ring 16, allowing the mounting cover 8 to rotate synchronously with the rotating shaft 10. A contact ring 7 with an inner surface containing an energized block 26 is installed at the bottom of the mounting cover 8, with the energized block 26 corresponding to the position of the contact block 22. For ease of viewing, multiple indicator lights 18 are mounted on the top of the mounting cover 8 via multiple bases 17, with the number and position of the indicator lights corresponding to the contact blocks 22. This design, using a simple energized light principle, allows for real-time monitoring of the opening angle of the disc 14 in the valve, increasing the safety of valve operation.
