Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, and in particular to an online disassembly and assembly tooling for top-mounted ball valves. Background Technology
[0002] With the rapid development of industries such as petroleum and chemical engineering, the demand for valves is gradually increasing. Traditional ball valves, with their side-mounted, split structure, require disassembly from the pipeline for maintenance, leading to long downtime and high labor costs, which is unacceptable, especially in critical areas such as petrochemicals and long-distance pipelines. In contrast, top-entry ball valves utilize simple, portable, and safe online disassembly and assembly fixtures. These fixtures allow for on-site disassembly and maintenance on the pipeline, significantly reducing maintenance time and making them an optimal choice for quickly resolving valve issues. Summary of the Invention
[0003] According to an embodiment of the present utility model, an online disassembly and assembly fixture for a top-mounted ball valve is provided, comprising:
[0004] Valve body;

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.
[0035] First, combine Figures 1-10 This invention describes an online disassembly and assembly tool for a top-mounted ball valve according to an embodiment of the present invention, which is used for the rapid disassembly and assembly of the ball valve and has a wide range of applications.
[0036] like Figures 1-10 As shown in the figure, an online disassembly and assembly fixture for a top-mounted ball valve according to an embodiment of the present invention includes a valve body 100, two valve seats 200, and a ball 400. The two valve seats 200 are mounted opposite each other on the inner sides of the valve body 100, and a spring 300 is provided between each valve seat 200 and the valve body 100; the ball 400 is mounted between the two valve seats 200. It also includes a fixture body 500, an insertion module, and an extraction module.
[0037] Specifically, such as Figures 1-2 As shown in Figures 4, 6 to 10, the bottom of the tooling body 500 is provided with a guide surface 501, and the tooling body 500 has a hollow part 502.
[0038] Specifically, such as Figures 1-2 As shown in Figures 6-9, the loading module is used to load the tooling body 500 into the valve body 100. The guide surface 501 gradually contacts the two valve seats 200, causing the two valve seats 200 to move and compress the corresponding springs 300. At this time, the ball 400 can be hoisted through the hollow part 502 and enter the valve body 100.
[0039] Specifically, such as Figure 4 , 10 As shown, the removal module is used to remove the tooling body 500 from the valve body 100. The guide surface 501 gradually separates from the two valve seats 200, so that the spring 300 resets and the two valve seats 200 move to clamp the ball 400, thus completing the installation of the ball valve.
[0040] Furthermore, such as Figures 1-2 As shown in Figures 6-9, the loading module includes: multiple studs 601, multiple through holes 602, and multiple nuts 603. The bottom ends of the multiple studs 601 are detachably connected to the top of the valve body 100. The top of a conventional valve body 100 is provided with multiple connection holes 101 (such as 4 or 8). The number of studs 601 matches the number of connection holes 101 on the top of the conventional valve body 100. The bottom ends of the studs 601 are threadedly connected to the connection holes 101 on the top of the valve body 100. Multiple through holes 602 are opened on the top of the tooling body 500. The number of through holes 602 matches the number of studs 601. The tooling body 500 is fitted onto the multiple studs 601 through the multiple through holes 602. The number of nuts 603 matches the number of studs 601. The multiple nuts 603 are respectively and correspondingly set on the multiple studs 601. By tightening the nuts 603 in sequence, the tooling body 500 can move downward. In this embodiment, there are 8 studs 601, through holes 602, and nuts 603.
[0041] Furthermore, such as Figure 4 , 10 As shown, the removal module includes multiple threaded holes 701 and multiple bolts 702. The multiple threaded holes 701 are located on the top of the fixture body 500. The number of bolts 702 matches the number of threaded holes 701, and each bolt 702 is connected to one of the multiple threaded holes 701. When it is necessary to remove the fixture body 500, the bottom of the multiple bolts 702 contacts the top surface of the valve body 100, and then each bolt 702 is rotated clockwise once. By repeating this process, the relative forces are used to slowly move the fixture body 500 upwards and detach it.
[0042] Furthermore, such as Figure 5 As shown, the valve seat 200 is provided with a fillet 201 for engagement with the guide surface 501 on the tooling body 500.
[0043] Furthermore, such as Figure 5 As shown, the valve seat 200 is provided with a sealing surface 202 and an end face 203. The end face 203 is located outside the sealing surface 202. The sealing surface 202 is designed to avoid the end face 203 to ensure that the sealing surface 202 is not damaged during the tooling lowering process.
[0044] Furthermore, such as Figure 3 As shown, the top of the sphere 400 is provided with a lifting hole 401, which makes it convenient to put the sphere 400 in and out during disassembly and assembly.
[0045] Furthermore, the surfaces of the tooling body 500 and the valve seat 200 are coated to increase hardness and prevent deformation.
[0046] Assembly principle:
[0047] S1: Two valve seats 200 are placed in the valve body 100, and the spring 300 remains in a free state. Figure 5 As shown;
[0048] S2: The bottom ends of multiple studs 601 are threaded into the connecting holes 101 at the top of the valve body 100. The fixture body 500 is then inserted, and it is fitted onto the studs 601 through multiple through holes 602. The bottom of the fixture body 500 supports the valve seat 200 in its free state, exposing the studs 601. Figure 6 As shown;
[0049] S3: Tighten the exposed stud 601 with the nut 603, and tighten the nuts 603 in sequence to make the tooling body 500 move downwards. Passing through the guide surface 501 of the tooling body 500, the valve seats 200 are slowly opened, so that the two valve seats 200 are opened to their maximum width. Figure 7 As shown;
[0050] S4: After opening, hoist and insert the ball 400. Position it at the center of the two valve seats 200, then rotate the ball 400 (90 degrees) so that the blocking surface 402 of the ball 400 faces the valve seat 200. Figure 8 As shown;
[0051] S5: After the ball 400 rotates, remove multiple nuts 603 (screw nuts 603 to the top of studs 601 (leave at least two), as there may be a risk of the fixture body 500 popping out during removal; nuts 603 can prevent the fixture body 500 from popping out and ensure personal safety). Insert multiple bolts 702 into multiple threaded holes 701 on the fixture body 500, with the bottom of the bolts 702 contacting the top surface of the valve body 100. Rotate each bolt 702 clockwise one revolution in sequence, repeating the cycle. Use the opposing forces to slowly move the fixture body 500 upwards until the valve seat 200, under the elastic force of the spring 300, adheres to the surface of the ball 400. After assembly, completely remove the fixture body 500, disassemble the corresponding structure, and install the valve cover. Figure 9 As shown.
[0052] Demolition principle:
[0053] First, remove the valve cover;
[0054] Perform steps S2-S3 as described above, and then lift and remove the sphere 400.
[0055] Finally, remove the main tooling body 500 and the valve seat 200.
[0056] Above, refer to Figures 1-10 This invention describes an online disassembly and assembly fixture for a top-mounted ball valve according to an embodiment of the present invention, which enables rapid disassembly and assembly of the ball valve, is more efficient, and reduces maintenance time.
