Description

Technical Field

[0001] This utility model relates to the field of angle valve disassembly and assembly technology, and in particular to an angle valve disassembly and assembly fixture. Background Technology

[0002] A high-vacuum angle valve is a specialized shut-off valve installed between the chamber and the vacuum pump. It controls the start or stop of vacuuming by opening and closing the valve. Because some byproducts and impurities may enter the high-vacuum angle valve through pipes, it needs to be disassembled for maintenance after excessive accumulation of foreign matter. A common type is the SMC high-vacuum angle valve. This valve has a valve stem on the back of the sealing plate, which passes through a spring and the cylinder body before connecting to the piston via a nut. During disassembly, the spring is compressed, so if the connecting nut loosens, there is a safety hazard of the spring suddenly ejecting and striking the operator. Furthermore, existing assembly methods often require two operators to work together, manually compressing the spring for installation, which not only increases the difficulty of operation but also significantly impacts work efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose a jig for disassembling and assembling angle valves, which aims to solve the problem that existing angle valves are inconvenient to disassemble for maintenance.

[0004] To achieve the above objectives, this utility model proposes a jig for disassembling and assembling an angle valve, used to assist in the disassembly and assembly of the angle valve. The angle valve includes a cylinder, a spring, a sealing plate, a piston, and a fixing component for fixing the valve stem and the piston. The jig for disassembling and assembling the angle valve includes:

[0005] A base having a receiving portion for accommodating the valve stem;

[0006] A connector is detachably disposed on the base. The connector is configured to be movably connected to the cylinder body and to make the position of the cylinder body relative to the sealing plate adjustable. The spring is disposed between the cylinder body and the sealing plate. The connector is used to push the cylinder body toward the sealing plate and compress the spring under the action of an external force, so that the fixing member extends out of the cylinder body for external devices to install and remove.

[0007] In one embodiment, the base further has a connecting portion connected to the connector, and the number of the connecting portions is at least two, with the two connecting portions located on opposite sides of the receiving portion.

[0008] In one embodiment, each of the connecting portions includes a plurality of connecting holes, which are arranged at intervals along a direction from the receiving portion to one side of the base.

[0009] In one embodiment, the diameter of the plurality of connecting holes is gradually increased along the direction from the receiving portion to one side of the base.

[0010] In one embodiment, the base is rectangular.

[0011] In one embodiment, the two connecting portions are located on opposite sides of the base.

[0012] In one embodiment, the number of connectors is the same as the number of connecting parts;

[0013] The connector is a screw-in connector;

[0014] The cylinder body has a through hole for the threaded connector to pass through. The threaded connector includes a screw rod passing through the through hole and a nut abutting against the cylinder body. The screw rod is threadedly connected to the connecting part.

[0015] In one embodiment, the base includes a base body and an anti-slip member. The base body and the anti-slip member are respectively provided with the receiving portion and the connecting portion. The base body has a first surface and a second surface facing each other.

[0032] A high-vacuum angle valve is a specialized shut-off valve installed between the chamber and the vacuum pump. It controls the start or stop of vacuuming by opening and closing the valve. Because some byproducts and impurities may enter the high-vacuum angle valve through pipes, it needs to be disassembled for maintenance after excessive accumulation of foreign matter. A common type is the SMC high-vacuum angle valve. This valve has a valve stem on the back of the sealing plate, which passes through a spring and the cylinder body before connecting to the piston via a nut. During disassembly, the spring is compressed, so if the connecting nut loosens, there is a safety hazard of the spring suddenly ejecting and striking the operator. Furthermore, existing assembly methods often require two operators to work together, manually compressing the spring for installation, which not only increases the difficulty of operation but also significantly impacts work efficiency.

[0033] This utility model proposes a jig for disassembling and assembling an angle valve, which can be a high-vacuum angle valve.

[0034] Please see Figures 1 to 5 In one embodiment of this utility model, the angle valve disassembly and assembly fixture is used to assist in the disassembly and assembly of the angle valve. The angle valve includes a cylinder body 5, a spring 7, a sealing plate 6, a piston 9, and a fixing member 10 for fixing the valve stem 8 and the piston 9. The angle valve disassembly and assembly fixture includes a base 1 and a connecting member 4. The base 1 has a receiving portion 12 for accommodating the valve stem 8. The connecting member 4 is detachably disposed on the base 1. The connecting member 4 is configured to be movably connected to the cylinder body 5 and to make the position of the cylinder body 5 relative to the sealing plate 6 adjustable. The spring 7 is disposed between the cylinder body 5 and the sealing plate 6. The connecting member 4 is used to push the cylinder body 5 toward the sealing plate 6 under the action of external force and squeeze the spring 7 so that the fixing member 10 extends out of the cylinder body 5 for external devices to disassemble and assemble.

[0035] The technical solution of this utility model is to facilitate the disassembly and maintenance of angle valves, specifically high-vacuum angle valves (hereinafter referred to as angle valves). In this embodiment, the sealing plate 6 of the angle valve is first placed on the base 1, and the valve stem 8 protruding from the sealing plate 6 is aligned with the receiving portion 12 provided on the base 1, so that the angle valve can be stably placed on the base 1 through the sealing plate 6. Then, the connecting piece 4 is installed on the base 1. It is worth mentioning that when the connecting piece 4 is installed on the base 1, at least part of it is connected to the cylinder body 5 of the angle valve, that is, it has a connection relationship with the cylinder body 5 of the angle valve. When the connecting piece 4 is installed on the base 1, it can be squeezed from the top of the angle valve, that is, it can squeeze the cylinder body 5. When the cylinder body 5 is subjected to the thrust of the connecting piece 4, the spring 7 located between the cylinder body 5 and the sealing plate 6 will be compressed. Due to the connection between the connecting piece 4 and the base 1, the compressed spring 7 cannot rebound. At this time, the fixing piece 10 that fixes the valve stem 8 and the piston 9 in the angle valve will extend out of the cylinder body 5, so that the user can easily use tools to disassemble the fixing piece 10. After the fixing piece 10 is disassembled, the cylinder body 5 of the angle valve will still be limited to the current position due to the restriction of the connecting piece 4, thereby preventing the accident that the spring 7 will quickly rebound and push the cylinder body 5 out after the valve stem 8 and the piston 9 are disassembled, thus preventing the user from being injured. By setting up the base 1 and the connector 4, and by utilizing the cooperation between the connector 4 and the base 1 to limit the cylinder 5, the user can disassemble or install the angle valve independently. Also, due to the setting of the base 1 and the connector 4, it can effectively prevent the spring 7 from quickly rebounding and pushing the cylinder 5 out after the fixing part 10 is disassembled, thus preventing accidents that could cause injury to the user.

[0036] It is understood that, in this embodiment, as Figure 6As shown, the angle valve includes a cylinder body 5, a spring 7, a sealing plate 6, a piston 9, a valve stem 8, and a fixing member 10 for fixing the piston 9 and the valve stem 8. The cylinder body 5 has a cavity, and the piston 9 is movably disposed within the cavity of the cylinder body 5. The valve stem 8 passes through the sealing plate 6, the spring 7, and the piston 9 sequentially from bottom to top. The fixing member 10 is located at the end of the valve stem 8, close to the piston 9, and is mainly used to fix the valve stem 8 and the piston 9 together. The spring 7 is disposed between the sealing plate 6 and the cylinder body 5. The spring 7 is mainly used to keep the cylinder body 5 in its initial position when no force is applied, and in other positions when force is applied. The initial position can be either a closed state between the piston 9 and the cylinder body 5, or an open state between the piston 9 and the cylinder body 5. Other positions are the opposite of the initial position; that is, when the piston 9 and the cylinder body 5 are closed in the initial position, they are open in other positions, and vice versa. No further limitations are imposed on this. It is also understandable that the fastener 10 may include a fixing nut and a retaining ring, and no further restrictions are imposed on this.

[0037] It is worth mentioning that the receiving part 12 can be a groove, an opening, or a limiting groove or limiting hole that is adapted to the valve stem 8 and has a limiting function for the valve stem 8. No further restrictions are imposed on this.

[0038] In one embodiment, the base 1 further has a connecting portion 11 connected to the connector 4. There are at least two connecting portions 11, located on opposite sides of the receiving portion 12. To facilitate a detachable connection between the connector 4 and the base 1, in this embodiment, the base 1 is provided with a connecting portion 11, which can be a limiting opening or a threaded hole 13, primarily used for snap-fitting or screwing the connector 4. To ensure the connector 4 provides good limiting and positioning for the cylinder of the angle valve, in this embodiment, at least two connecting portions 11 (not shown in the figure) are provided, located on opposite sides of the receiving portion 12. When the user uses the connector 4 to engage with the connector 11 to position the cylinder 5, the user can use the two connectors to engage with the two connectors 11 respectively to position the cylinder 5 on opposite sides. This allows the cylinder 5 to be more stably positioned in its current position, making it easier for the user to disassemble the fixing member 10 using an external device, while also preventing the cylinder 5 from flying off and causing injury to the user. Of course, in other embodiments, such as... Figure 1 As shown, the number of connecting parts 11 can also be four, with the four connecting parts 11 arranged at equal angles around the receiving part 12.

[0039] In one embodiment, each connecting portion 11 includes a plurality of connecting holes 111, which are arranged at intervals along a direction from the receiving portion 12 to one side of the base 1. To improve the applicability of the angle valve assembly / disassembly fixture, for example, Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, each connecting part 11 includes a plurality of connecting holes 111. The plurality of connecting holes 111 are arranged sequentially at intervals along the direction from the receiving part 12 to the side of the base 1. The arrangement of the plurality of connecting holes 111 enables the angle valve disassembly and assembly fixture to assist in the disassembly and assembly of angle valves of different diameters, thereby making the angle valve disassembly and assembly fixture more applicable.

[0040] In one embodiment, the diameter of the plurality of connecting holes 111 gradually increases along the direction from the receiving portion 12 to one side of the base 1. Exemplarily, in this embodiment, the diameter of the plurality of connecting holes 111 also gradually increases along the direction from the receiving portion 12 to one side of the base 1. This arrangement is mainly to take into account that larger diameter angle valves require the use of larger diameter connectors 4, so as to maintain the strength of connectors 4 to cope with angle valves of different masses.

[0041] In one embodiment, the base 1 is rectangular. For example... Figure 1 As shown, in this embodiment, the base 1 is rectangular. Of course, in other embodiments, the base 1 can also be circular. The specific shape of the base 1 is not limited.

[0042] In one embodiment, two connecting portions 11 are located on the diagonal of the base 1. To make efficient use of the rectangular base 1, in this embodiment, the two connecting portions 11 are located on the same diagonal of the base 1, and on opposite sides of the receiving portion 12. That is, the receiving portion 12 is located at the intersection of the two diagonals of the rectangular base 1, while the two connecting portions 11 are located on both sides of the receiving portion 12, on the same diagonal. This arrangement allows for greater utilization of the rectangular base 1, increasing the number of connecting holes 111 that can be opened in each connecting portion 11, thereby enabling the base 1 to accommodate angle valves of various sizes.

[0043] In one embodiment, the number of connecting members 4 is the same as the number of connecting parts 11; the connecting members 4 are threaded members; the cylinder body 5 has through holes 51 for the threaded members to pass through, and the threaded members include a screw 42 passing through the through hole 51 and a nut 41 abutting against the cylinder body 5, the screw 42 being threadedly connected to the connecting part 11. It is worth noting that the number of connecting members 4 is the same as the number of connecting parts 11, that is, when there are two connecting parts 11, there are two connecting members 4, each corresponding to one of the two connecting parts 11. Since each connecting part 11 has multiple connecting holes 111, if the diameters of the multiple connecting holes 111 are the same, then the number of connecting members 4 corresponds to the number of connecting parts 11. If the diameters of the multiple connecting holes 111 are different, then the number of connecting members 4 needs to be configured according to the number of connecting holes 111 in each connecting part 11, so that each connecting hole 111 in each connecting part 11 has a matching connecting member 4. In this embodiment, as... Figure 5 As shown, the connector 4 is a screw connector, which includes a screw 42 and a nut 41. In this embodiment, the cylinder body 5 has a through hole 51 for the screw 42 to pass through, and the nut 41 can abut against the cylinder body 5. In this embodiment, the user can rotate the screw connector through an external device so that the screw 42 is gradually screwed into the connecting hole 111, and the nut 41 gradually moves closer to the base 1. When the nut 41 gradually moves closer to the base 1, the nut 41 will simultaneously push the cylinder body 5 toward the sealing plate 6, so that the fixing member 10 connecting the valve stem 8 and the piston 9, which is originally housed in the cylinder body 5, gradually extends out of the cylinder body 5, thereby making it easier for the user to disassemble and assemble the fixing member 10 using an external device. Furthermore, since the screw connector is threadedly connected to the connecting hole 111, when the user loosens the screw connector, the cylinder 5 will be positioned in its current position due to the threaded connection between the screw connector and the base 1, and will not quickly spring back and push the cylinder 5 out. The user can slowly pull the screw connector out of the connecting hole 111 to allow the spring 7 to slowly recover its deformation and push the cylinder 5 to move away from the sealing plate 6. After the spring 7 has completed its deformation recovery, the user can completely remove the screw connector from the connecting hole 111 and then disassemble the cylinder 5, piston 9, valve stem 8, spring 7, and sealing plate 6 of the angle valve. This setting allows the user to disassemble or assemble the angle valve more quickly.

[0044] In one embodiment, the base 1 includes a base body and an anti-slip member 3. The base body and the anti-slip member 3 are respectively provided with a receiving portion 12 and a connecting portion 11. The base body has a first surface and a second surface facing each other. A receiving groove 1a is recessed on the first surface, and the anti-slip member 3 is embedded in the receiving groove 1a. Figure 1 and Figure 2As shown, in this embodiment, to prevent the angle valve from sliding when placed on the base 1, the base 1 includes a base body and an anti-slip component 3. The base body has a first surface and a second surface, which are two surfaces along its thickness direction. A receiving groove 1a is recessed on the first surface of the base body for installing the anti-slip component 3, which can be embedded in the receiving groove 1a. It is worth mentioning that, to prevent the anti-slip component 3 from sliding out of the receiving groove 1a, in this embodiment, fasteners are used to detachably place the anti-slip component 3 in the receiving groove 1a. Of course, in other embodiments, glue can also be used to place the anti-slip component 3 in the receiving groove 1a, and there are no further limitations on this. With this setting, the pre-placement effect of the angle valve on the angle valve of the angle valve assembly / disassembly fixture can be improved, and the sliding phenomenon of the angle valve on the base 1 can be effectively prevented.

[0045] In one embodiment, the anti-slip element 3 is a nylon pad. In other embodiments, the anti-slip element 3 may also be a rubber pad, or it may be a silicone pad; there are no further limitations on this.

[0046] In one embodiment, the angle valve assembly / disassembly fixture further includes multiple support feet 2, which are detachably mounted on the second surface of the base body. To ensure the base 1 can stably support the angle valve, as shown... Figure 3 and Figure 4 As shown, in this embodiment, a support foot 2 is detachably provided on the base 1. There are multiple support feet 2. The support feet 2 are specifically provided on the second surface of the base body. Similarly, the support feet 2 can be detachably provided on the base body by fasteners, or they can be installed on the base body by means of snap-fit ​​or glue. No further limitations are imposed on this.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
