Description

Technical Field

[0001] This application relates to the field of disassembly and assembly tools, specifically a safe and quick disassembly and assembly tool for gas pressure regulating equipment. Background Technology

[0002] like Figures 1 to 3 The diagram shows a schematic of an existing pressure regulator, suitable for applications involving sudden changes in flow rate or rapid shut-off of the gas supply using a solenoid valve, typically found in industrial or domestic boilers. During routine use, the internal sealing ring 500 of the regulator needs periodic replacement due to aging. However, existing technology lacks specialized disassembly and assembly tools for this type of pressure regulator, resulting in difficulties, low efficiency, and reduced safety during disassembly and assembly.

[0003] Therefore, how to provide an effective disassembly and assembly tool that overcomes the above-mentioned shortcomings is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One objective of this application is to provide a safe and quick disassembly and assembly tool for gas pressure regulating equipment that is easy to disassemble and assemble, has high disassembly and assembly efficiency, high disassembly and assembly safety, and does not damage the sealing ring during assembly.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a safe and quick disassembly and assembly tool for a gas pressure regulating device, comprising an insert rod, a stop member, and a clamping member. The stop member abuts against the lower end of the regulator body; the insert rod is disposed on the stop member, and its upper end passes through the interior of the regulator body to the top of the pressure cap; the clamping member is detachably disposed on the upper end of the insert rod and is used to press down on the pressure cap. The position of the insert rod can be adjusted up and down relative to the stop member, and / or the position of the clamping member can be adjusted up and down relative to the insert rod.

[0006] Preferably, the abutting component includes a sleeve and a abutting part; the abutting part is disposed in the sleeve and abuts against the lower end face of the lower flange ring of the pressure regulator body. The inserting rod is inserted into the sleeve, and the lower end of the inserting rod is provided with a limiting part, the position of the limiting part and / or the clamping part can be adjusted up and down relative to the inserting rod. Its advantages are as follows: In use, the blocking component is placed against the lower end face of the flange ring at the lower end of the pressure regulator body, and the inserting rod is inserted into the inside of the sleeve, thereby maintaining the vertical posture of the inserting rod so that the upper end of the inserting rod extends to the top of the pressure cap, thereby assembling with the clamping component; then, by gradually lowering the height of the clamping component relative to the inserting rod downwards, or gradually raising the height of the limiting part relative to the inserting rod upwards, the distance between the limiting part and the clamping component gradually decreases, thereby pressing the clamping component against the pressure cap, and the limiting part abutting against the lower end of the sleeve; similarly, in the reverse operation, the pressure cap will gradually move upwards, thereby gradually releasing the elastic force of the spring.

[0007] Preferably, the position of the abutting component can be adjusted vertically relative to the sleeve. The advantage is that, since the abutting component always contacts the lower end face of the flange ring, when the position of the abutting component is adjusted upwards relative to the sleeve, it is equivalent to lowering the height of the lower end of the sleeve. Therefore, with the initial distance between the clamping member and the limiting part remaining the same, the clamping member can press against the pressure cap with a smaller downward adjustment (or the limiting part can be adjusted upwards with a smaller adjustment), which is suitable for smaller pressure regulators. Conversely, when the position of the abutting component is adjusted downwards relative to the sleeve, it is equivalent to raising the height of the lower end of the sleeve, which is suitable for larger pressure regulators.

[0008] Preferably, the blocking component includes a first locking member, a second locking member, and two clamping arms; the two clamping arms abut against the lower end face of the flange ring, and a channel for adapting the sleeve is provided vertically between the two clamping arms; the first locking member and the second locking member are both disposed on the two clamping arms, the first locking member is used to lock the two clamping arms, and the second locking member is used to lock the channel and the sleeve. Its advantage is that by unlocking the first locking member, the two clamping arms can be opened, thus facilitating the direct clamping of the channel between the two clamping arms at any position on the sleeve, thereby eliminating the cumbersome operation of gradually adjusting the blocking component upwards or downwards. In addition, the first locking member can lock the two clamping arms into a whole, and the second locking member can lock the sleeve and the channel, thereby preventing displacement between the sleeve and the channel (i.e. the two clamping arms); furthermore, when the second locking member is not locked, the channel can move up and down along the sleeve to fine-tune the position of the two clamping arms.

[0009] Preferably, a through hole is provided vertically between the two clamping arms to accommodate the bolt post at the lower end of the flange ring. The advantage is that by engaging the through hole with the bolt post connected to the lower end face of the flange ring, the two clamping arms can be limited, thereby preventing them from rotating synchronously when the sleeve is rotated.

[0010] Preferably, the through hole is suitable to be an elongated structure, and the length direction of the through hole is arranged along the radial direction of the sleeve. Its advantage is that different models of pressure regulators will have different diameters of the flange ring at their lower ends, meaning the distance between the bolt post and the flange ring axis will vary. When the through hole is an elongated structure, it can perfectly accommodate this variation, thus increasing its versatility.

[0011] Preferably, the second locking element is a threaded connection between the sleeve and the channel. Its advantages are: the threaded connection enables locking between the sleeve and the channel, as well as vertical adjustment; that is, when the two clamping arms rotate relative to the sleeve, the threads between them allow both clamping arms to move simultaneously upwards or downwards, thus enabling fine-tuning; when the two clamping arms stop rotating, the threads between them also provide self-locking.

[0012] Preferably, each of the two clamping arms has a mounting groove corresponding to the position of the channel; the second locking member includes two arc-shaped plates, which are respectively disposed in the two mounting grooves, and the inner annular surface of the arc-shaped plates is threaded to the sleeve. Its advantage is that the working principle of this solution is the same as that of directly setting internal threads on the inner wall of the channel, but with this solution, when the threads on the arc-shaped plates wear, only the arc-shaped plates need to be replaced, without replacing the clamping arms, resulting in lower maintenance costs in the later stages.

[0013] Preferably, the upper end of the sleeve is adapted to have a support portion for abutting against the valve stem sleeve. The upper end of the support portion has a frustum-shaped structure, and the support portion has clearance holes extending through it vertically for the passage of the insert rod. The advantage is that by having the frustum-shaped structure at the upper end of the support portion abut against the valve stem sleeve, the upper end of the sleeve is effectively further fixed, thus contributing to a more stable system. Furthermore, the frustum-shaped structure can accommodate valve stem sleeves of different inner diameters, offering greater versatility. In addition, when the position of the abutting component can be adjusted vertically relative to the sleeve, it can accommodate different types of pressure regulators. That is, different types of pressure regulators have different distances between the lower end face of the flange ring and the valve stem sleeve. Therefore, by adjusting the position of the abutting component vertically relative to the sleeve, the abutting component can always abut against the lower end face of the flange ring, and the frustum-shaped structure at the upper end of the support portion can always abut against the valve stem sleeve.

[0014] Preferably, the lower end of the sleeve is adapted to have a rotating part. The advantage is that since the two clamping arms can be rotated relative to the sleeve, or the sleeve can be rotated relative to the two clamping arms, adjustment can be achieved, allowing the frustum-shaped structure at the upper end of the support to abut against the valve stem sleeve, and the two clamping arms to simultaneously abut against the lower end face of the flange ring. Furthermore, the rotating part facilitates the rotational adjustment of the sleeve.

[0015] Preferably, the clamping member is threadedly connected to the insert rod. Its advantages are: during adjustment, only the insert rod needs to be fixed, and the clamping member can be rotated to adjust its position relative to the insert rod; when the clamping member is stopped from rotating, it can achieve self-locking due to the threaded connection between them.

[0016] Preferably, the clamping component includes a clamping sleeve and a locking ring. The clamping sleeve is slidably fitted onto the insert rod. The upper end of the clamping sleeve is provided with a plurality of snap-fit ​​portions spaced circumferentially. The locking ring is threadedly connected to the clamping sleeve. When the locking ring moves toward the clamping sleeve, the tapered surface on the locking ring forces the snap-fit ​​portions to deform radially inward along the clamping sleeve, thereby clamping the insert rod. Its advantages are as follows: When replacing the sealing ring, first rotate the locking ring to move it away from the compression sleeve. The snap-fit ​​part can recover its deformation under its own elastic force. At this time, the compression sleeve can slide up and down arbitrarily along the insertion rod. When the compression sleeve is pressed against the locking member, rotate the locking ring in the opposite direction to move it closer to the compression sleeve. The conical surface can force the snap-fit ​​part to deform radially inward, thereby clamping it on the insertion rod to achieve locking. After removing the lower cover, slowly loosen the locking ring to move it away from the compression sleeve. When the sum of the friction between the snap-fit ​​part and the insertion rod and the other friction forces in the whole system is slightly less than the elastic force of the spring on the cover, the cover and the compression sleeve will slowly move upward, thereby gradually releasing the elastic force of the spring. When assembling the cover, first loosen the locking ring and manually press down on the clamping sleeve. After pressing the cover into the chamber, tighten the locking ring to lock it in place, and then assemble the lower cover. In other words, regardless of whether it's disassembly or assembly, the locking ring can be loosened first, and the clamping sleeve can be slid directly to the designated position before tightening the locking ring to lock it in place. This method eliminates the cumbersome operation of gradually rotating the sleeve.

[0017] Compared with the prior art, the beneficial effects of this application are as follows: (1) When replacing the sealing ring of the pressure regulator using the safe and quick disassembly and assembly tool of the gas pressure regulator, first remove the parts on the pressure regulator that would block the disassembly and assembly tool, then place the abutment against the lower end of the pressure regulator body, and pass the insertion rod through the inside of the pressure regulator body, so that the upper end of the insertion rod passes through to the top of the pressure cap, and then assemble the clamping member to the upper end of the insertion rod; then, adjust the height of the clamping member downward relative to the insertion rod, or adjust the height of the abutment against the pressure cap. The stop is lowered to reduce the height of the insert rod, thereby pressing the clamping member against the cover. Next, the mounting bolts on the lower cover are removed, and the lower cover is removed. At this point, because the clamping member is pressed against the cover, it counteracts the spring force on the cover, preventing the cover from popping out. Finally, the height of the clamping member is gradually increased relative to the insert rod, or the height of the insert rod is gradually increased relative to the stop, causing the cover to rise gradually and releasing the spring force. In other words, the entire disassembly process does not require manual pressure on the lower cover, making the operation simpler and more efficient. Furthermore, since the cover is restrained by the insert rod throughout the disassembly process, it cannot be popped out by the spring, ensuring higher safety.

[0018] (2) After removing the cover and replacing the sealing ring, similarly, by lowering the height of the clamping member relative to the inserting rod or the height of the inserting rod relative to the blocking member, the clamping member gradually lowers the height of the cover, thereby gradually compressing the spring until the cover is fully inserted into the chamber. Then, the lower cover is assembled. After the mounting bolts on the lower cover are installed, the safe and quick disassembly and assembly tools for the gas pressure regulating device can be removed. In other words, the entire assembly process does not require manual pressing of the cover into the chamber through the lower cover, making the operation simpler and more efficient. Moreover, the cover is restricted to the inserting rod throughout the assembly process, so the cover cannot be ejected by the spring, resulting in higher safety. In addition, during the process of pressing the cover into the chamber, since the lower cover does not obstruct the operator's view, the operator can observe the real-time condition of the outer circumference of the cover, thereby avoiding shearing action on the sealing ring and preventing damage to the sealing ring, which helps to extend the service life of the sealing ring.

The terms "comprising" and "having," and any variations thereof, in the specification and claims of this application, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0042] Reference Figure 3 One embodiment of this application provides a safe and quick disassembly and assembly tool for a gas pressure regulator, including an insertion rod 1, a stop 2, and a clamping member 3. The stop 2 abuts against the lower end of the regulator body; the insertion rod 1 is disposed on the stop 2, and its upper end passes through the interior of the regulator body to the top of the pressure cap 200; the clamping member 3 is detachably disposed on the upper end of the insertion rod 1 and is used to press down on the pressure cap 200. The position of the insertion rod 1 can be adjusted up and down relative to the stop 2; alternatively, the position of the clamping member 3 can also be adjusted up and down relative to the insertion rod 1.

[0043] The working principle of this safe and quick disassembly tool for gas pressure regulating equipment is as follows: When replacing the 500 sealing ring of the pressure regulator, first remove the parts on the pressure regulator that might obstruct the disassembly tool. The specific removal process is as follows: Figure 11 As shown, first remove the upper cover 10 and the adjusting mechanism 20 at the upper end of the upper cover 10, then remove the fixing part 50 at the upper end of the valve stem 70 that is used to fix the pressure plate 40, and then the pressure plate 40 and the diaphragm 30 can be removed in sequence; next, remove the flange cover 60 at the lower end of the flange ring 70, and then the limiting part 80 used to position the upper end of the valve stem 70 and the supporting part 90 used to support the lower end of the valve stem 70 can be removed, and then the valve stem 70 can be pulled out. After removal, as shown... Figure 12 As shown.

[0044] like Figure 14As shown, after removing the obstruction, the stop 2 is placed against the lower end of the regulator body, and the insert rod 1 is passed through the inside of the regulator body, so that the upper end of the insert rod 1 extends above the pressure cap 200. Then, the clamping member 3 is assembled onto the upper end of the insert rod 1. Next, the height of the clamping member 3 is lowered relative to the insert rod 1 (or the height of the insert rod 1 is lowered relative to the stop 2), so that the clamping member 3 is pressed against the pressure cap 200 (e.g., Figure 15 and Figure 16 (As shown); Next, remove the mounting bolts 300 on the lower cover 100 and remove the lower cover 100 (as shown). Figure 18 As shown), at this time, since the clamping member 3 is pressed against the cover 200, the elastic force of the spring 400 on the cover 200 can be offset, so the cover 200 will not be popped out; finally, the height of the clamping member 3 is gradually adjusted upward relative to the inserting rod 1 (or the height of the inserting rod 1 is gradually adjusted upward relative to the blocking member 2), so that the cover 200 gradually rises, so as to gradually release the elastic force of the spring 400 (e.g., Figure 19 As shown, the sealing ring 500 on the outer periphery of the cover 200 can be replaced. In other words, the entire disassembly process does not require manual pressing of the lower cover 100, making the operation simpler and more efficient. Furthermore, the cover 200 is confined to the insertion rod 1 during the entire disassembly process, so the cover 200 cannot be popped out by the spring 400, thus ensuring higher safety.

[0045] After replacing the sealing ring 500 on the outer periphery of the pressure cap 200, similarly, by lowering the height of the clamping member 3 relative to the inserting rod 1 (or lowering the height of the inserting rod 1 relative to the abutment member 2), the clamping member 3 gradually presses down the height of the pressure cap 200, thereby gradually compressing the spring 400 until the pressure cap 200 is fully inserted into the chamber 600. Then, the lower cover 100 is assembled. After the mounting bolts 300 on the lower cover 100 are installed, the safe and quick disassembly and assembly tools for this gas pressure regulating device can be removed. In other words, the entire assembly process does not require manual pressing of the pressure cap 200 into the chamber 600 through the lower cover 100, making the operation simpler and more efficient. Furthermore, the pressure cap 200 is confined to the inserting rod 1 throughout the assembly process, so the pressure cap 200 cannot be ejected by the spring 400, resulting in higher safety. Additionally, if... Figure 19 As shown, during the process of pressing the gland 200 into the chamber 600, since there is no cover 100 to block it, the operator can observe the real-time condition of the outer periphery of the gland 200, thereby avoiding the sealing ring 500 from being subjected to shearing action, thus preventing damage to the sealing ring 500 and helping to extend the service life of the sealing ring 500.

[0046] It should be understood that, such as Figure 12 and Figure 13As shown, without this disassembly tool, once the mounting bolts 300 on the lower cover 100 are removed, the pressure cap 200 will be instantly ejected by the spring force of the spring 400. This could easily cause the lower cover 100 and the pressure cap 200 to injure the operator, posing a significant safety hazard. Even experienced operators, knowing that the pressure cap 200 will be ejected by the spring 400, might manually hold down the lower cover 100 during disassembly, and then slowly lift it after removing the mounting bolts 300, gradually releasing the spring force of the spring 400 on the pressure cap 200. This inevitably leads to a more difficult and inefficient disassembly process, and improper operation could easily result in injury from the pressure cap 200, still posing a safety hazard. Similarly, after replacing the sealing ring 500, the pressure cap 200 needs to be slowly pressed into the chamber 600 through the lower cover 100. This assembly process is difficult and inefficient, and improper operation poses safety hazards. Furthermore, the lower cover 100 obstructs the operator's view, preventing them from observing the real-time condition of the pressure cap 200. This makes the sealing ring 500 susceptible to shearing damage when entering the chamber 600, thus shortening its lifespan. As explained in the principle section of this disassembly and assembly tool, using this tool avoids these problems during the disassembly and assembly process.

[0047] Reference Figure 4 , Figure 6 as well as Figure 14 In some embodiments of this application, the abutment 2 includes a sleeve 21 and abutment component 22; the abutment component 22 is disposed in the sleeve 21 and abuts against the lower end face of the lower flange ring 700 of the pressure regulator body. An insert rod 1 is inserted into the sleeve 21, and a limiting part 11 is provided at the lower end of the insert rod 1. The position of the limiting part 11 (and / or the clamping member 3) can be adjusted up and down relative to the insert rod 1. Figure 10 As shown, during use, the blocking component 22 is placed against the lower end face of the flange ring 700 at the lower end of the pressure regulator body, and the inserting rod 1 is inserted into the inside of the sleeve 21, thereby maintaining the vertical posture of the inserting rod 1 so that the upper end of the inserting rod 1 extends to the top of the pressure cap 200. The clamping component 3 can then be assembled onto the upper end of the inserting rod 1. Then, the height of the clamping component 3 is gradually lowered relative to the inserting rod 1 (or the height of the limiting part 11 is gradually raised relative to the inserting rod 1), thereby gradually reducing the distance between the limiting part 11 and the clamping component 3, thus pressing the clamping component 3 against the pressure cap 200, and the limiting part 11 abuts against the lower end of the sleeve 21. Similarly, during reverse operation, the pressure cap 200 will gradually move upward, thereby gradually releasing the elastic force of the spring 400.

[0048] Understandably, when the position of the limiting part 11 can be adjusted up and down relative to the insert rod 1, the clamping member 3 can be directly and detachably installed on the upper end of the insert rod 1. Of course, the position of the clamping member 3 can also be adjusted up and down relative to the insert rod 1. Similarly, when the position of the clamping member 3 can be adjusted up and down relative to the insert rod 1, the limiting part 11 can be directly installed (or detachably installed) on the lower end of the insert rod 1. Of course, the position of the limiting part 11 can also be adjusted up and down relative to the insert rod 1.

[0049] Reference Figure 14 In some embodiments of this application, the position of the blocking component 22 can be adjusted up and down relative to the sleeve 21. It is understood that since the blocking component 22 always contacts the lower end face of the flange ring 700, when the position of the blocking component 22 is adjusted upwards relative to the sleeve 21, it is equivalent to lowering the height of the lower end of the sleeve 21. Therefore, with the initial distance between the clamping member 3 and the limiting part 11 being the same, the clamping member 3 can press against the pressure cap 200 with a smaller downward adjustment (or a smaller upward adjustment of the limiting part 11), which is suitable for smaller pressure regulators. Conversely, when the position of the blocking component 22 is adjusted downwards relative to the sleeve 21, it is equivalent to raising the height of the lower end of the sleeve 21, which is suitable for larger pressure regulators.

[0050] Reference Figure 5 as well as Figure 15 In some embodiments of this application, the upper end of the sleeve 21 is adapted to have a support portion 211 for abutting against the valve stem sleeve 800. The upper end of the support portion 211 has a frustum-shaped structure, and the support portion 211 is provided with clearance holes 2111 through it for the passage of the insert rod 1. Figure 16 As shown, by having the frustum-shaped structure at the upper end of the support 211 abut against the valve stem sleeve 800, the upper end of the sleeve 21 is further fixed, thus contributing to a more stable system. The frustum-shaped structure can accommodate valve stem sleeves 800 with different inner diameters, making it more versatile. The inclination angle of the frustum-shaped structure is suitable to be equal to the chamfer angle on the valve stem sleeve 800, typically 45°, to increase the contact area between the frustum-shaped structure and the valve stem sleeve 800; of course, it will not affect the use if the inclination angle of the frustum-shaped structure is not equal to the chamfer angle on the valve stem sleeve 800. In addition, when the position of the abutment component 22 can be adjusted up and down relative to the sleeve 21, it can be adapted to different models of pressure regulators. That is, different models of pressure regulators have different distances between the lower end face of the flange ring 700 and the valve stem sleeve 800. Thus, by adjusting the position of the abutment component 22 up and down relative to the sleeve 21, the abutment component 22 can always abut against the lower end face of the flange ring 700, and the frustum-shaped structure at the upper end of the support 211 can always abut against the valve stem sleeve 800.

[0051] Reference Figures 6 to 8In some embodiments of this application, the blocking component 22 includes a first locking member 222, a second locking member 223, and two clamping arms 221; the two clamping arms 221 abut against the lower end face of the flange ring 700, and a channel 2211 for adapting the sleeve 21 is provided vertically between the two clamping arms 221; the first locking member 222 and the second locking member 223 are both disposed on the two clamping arms 221, the first locking member 222 is used to lock the two clamping arms 221, and the second locking member 223 is used to lock the channel 2211 and the sleeve 21. By unlocking the first locking member 222, the two clamping arms 221 can be opened (e.g., Figure 8 As shown in the figure, this allows the channel 2211 between the two clamping arms 221 to be directly clamped at any position on the sleeve 21, thus eliminating the troublesome operation of gradually adjusting upwards or downwards; the two clamping arms 221 can be locked together as a whole by the first locking member 222, and the sleeve 21 and the channel 2211 can be locked together by the second locking member 223, thereby preventing displacement between the sleeve 21 and the channel 2211 (i.e., the two clamping arms 221); in addition, when the second locking member 223 is not locked, the channel 2211 (i.e., the two clamping arms 221) can also move up and down along the sleeve 21, so as to fine-tune the position of the two clamping arms 221.

[0052] This application does not limit the specific structure of the first locking member 222, as long as it can lock the two clamping arms 221 into a whole, for example, such as Figure 5 and Figure 7 As shown, the first locking element 222 is a hand-tightening bolt. The two clamping arms 221 can be locked and unlocked by rotating the hand-tightening bolt. Moreover, after unlocking (i.e., after gradually loosening the hand-tightening bolt), the two clamping arms 221 can still be connected by the hand-tightening bolt, but the distance between the two clamping arms 221 gradually increases.

[0053] This application does not limit the specific structure of the second locking member 223. Only two specific structures are provided below for reference (see Embodiment 1 and Embodiment 2 below).

[0054] Example 1: The second locking element 223 is a threaded connection between the sleeve 21 and the channel 2211. That is, the annular surface of the channel 2211 has an internal thread and the outer annular surface of the sleeve 21 has an external thread. The threaded connection can realize the locking between the sleeve 21 and the channel 2211 and the up and down adjustment operation. That is, when the two clamping arms 221 are rotated relative to the sleeve 21, under the action of the thread between them, the two clamping arms 221 can move upward or downward at the same time, so that fine adjustment can be made upward or downward; when the two clamping arms 221 stop rotating, under the action of the thread between them, self-locking can be achieved.

[0055] Example 2: Figures 6 to 10As shown, each of the two clamping arms 221 has a mounting groove 2213 corresponding to the position of the hole 2211; the second locking member 223 includes two arc-shaped plates 2231, which are respectively disposed in the two mounting grooves 2213, and the inner ring surface of the arc-shaped plates 2231 is threadedly connected to the sleeve 21. The working principle of this structure is the same as that of Embodiment 1. However, when the threads on the arc-shaped plates 2231 wear out, only the arc-shaped plates 2231 need to be replaced, without replacing the clamping arms 221, resulting in lower maintenance costs in the later stages. In addition, the method of fixing the arc-shaped plates 2231 to the mounting grooves 2213 is not limited. For example, the arc-shaped plates 2231 can be fixed by locking screws 2232.

[0056] It can be understood that in Embodiments 1 and 2, the two clamping arms 221 can be rotated relative to the sleeve 21, or the sleeve 21 can be rotated relative to the two clamping arms 221, thereby realizing the adjustment operation so that the frustum-shaped structure at the upper end of the support 211 can abut against the valve stem sleeve 800, and the two clamping arms 221 can simultaneously abut against the lower end face of the flange ring 700. In order to facilitate the rotation of the sleeve 21, a rotating part 212 is provided at the lower end of the sleeve 21, which facilitates the rotation and adjustment of the sleeve 21.

[0057] Reference Figure 6 as well as Figure 15 In some embodiments of this application, to prevent the two clamping arms 221 from rotating synchronously when the sleeve 21 is rotated, a through hole 2212 is provided vertically between the two clamping arms 221 to accommodate the bolt post at the lower end of the flange ring 700. Since the lower end of the flange ring 700 is also connected to a bolt, when the first locking member 222 is released, i.e., when the two clamping arms 221 are separated, the positions of the two clamping arms 221 corresponding to the through hole 2212 can be clamped onto the bolt post. Then, after locking the first locking member 222, the bolt post passes through the through hole 2212, thereby restricting the rotation of the two clamping arms 221. Figure 6 As shown, the through hole 2212 is further adapted to be a long strip structure, and the length direction of the through hole 2212 is arranged radially along the sleeve 21. Since the diameter of the lower flange ring 700 of different models of pressure regulators will also be different (that is, the distance between the bolt column and the axis of the flange ring 700 is different), when the through hole 2212 is a long strip structure, it can adapt to this change and has greater versatility.

[0058] It should be noted that this application does not limit the method of adjusting the clamping member 3 (or the limiting part 11) up and down relative to the inserting rod 1. In order to simplify the structure, either the clamping member 3 or the limiting part 11 can be adjusted up and down. The following only takes the adjustment and installation of the clamping member 3 as an example and provides two methods for reference (see Embodiment 3 and Embodiment 4 below for details).

[0059] Example 3: Figure 4 and Figure 15 As shown, the clamping member 3 is threadedly connected to the insert rod 1, allowing the vertical position of the clamping member 3 to be adjusted by rotating it. During adjustment, simply fix the insert rod 1 and rotate the clamping member 3 to adjust its position relative to the insert rod 1; when rotation of the clamping member 3 stops, it self-locks due to the threaded connection. Of course, the limiting part 11 can also adopt this structure.

[0060] Example 4: Figure 20 As shown, the clamping component 3 includes a clamping sleeve 31 and a locking ring 32. The clamping sleeve 31 is slidably fitted onto the insert rod 1. The upper end of the clamping sleeve 31 is provided with a plurality of snap-fit ​​portions 311 spaced apart along the circumference. The locking ring 32 is threadedly connected to the clamping sleeve 31. When the locking ring 32 moves toward the clamping sleeve 31, the tapered surface 321 on the locking ring 32 forces the snap-fit ​​portions 311 to deform radially inward along the clamping sleeve 31, thereby clamping the insert rod 1. When replacing the sealing ring 500, first rotate the locking ring 32 to move it away from the clamping sleeve 31. The locking part 311 recovers its deformation under its own elastic force (i.e., deforms radially outward along the clamping sleeve 31). At this time, the clamping sleeve 31 can slide freely up and down along the insertion rod 1. When the clamping sleeve 31 is pressed against the locking element, rotate the locking ring 32 in the opposite direction to move it closer to the clamping sleeve 31. The conical surface 321 forces the locking part 311 to move towards the clamping sleeve 31. 11 deforms radially inward, thus clamping onto the insert rod 1 to achieve locking. After removing the lower cover 100, slowly loosen the locking ring 32, causing it to slowly move away from the pressure sleeve 31. When the sum of the friction between the locking part 311 and the insert rod 1 and other frictions in the entire system is slightly less than the elastic force of the spring 400 on the cover 200, the cover 200 and the pressure sleeve 31 will slowly move upward, gradually releasing the elastic force of the spring 400. When assembling the cover 200 after replacing the sealing ring 500, first loosen the locking ring 32 and manually press down the pressure sleeve 31. After pressing the cover 200 into the chamber 600, tighten the locking ring 32 to achieve locking, and then assemble the lower cover 100. Of course, the limiting part 11 can also adopt this structure. In other words, regardless of the disassembly or assembly process, the locking ring 32 can be loosened first, and the clamping sleeve 31 can be slid directly to the designated position before tightening the locking ring 32 to achieve locking. Compared to Embodiment 3, this method in Embodiment 4 eliminates the cumbersome operation of gradually rotating the ring.

[0061] The safe and quick disassembly and assembly tools for this gas pressure regulating equipment also include the following steps: preparation, assembly, disassembly, replacement, and reassembly.

[0062] Preparation steps: Remove any parts on the voltage regulator that may obstruct the installation or removal tools. Specifically, such as... Figure 11 As shown, the top cover 10, adjusting mechanism 20, pressure plate 40, diaphragm 30, fixing component 50, flange cover 60, valve stem 70, limiting component 80, and support component 90 are removed. The disassembled state is as follows. Figure 12 As shown.

[0063] Assembly steps: First, remove the clamping part 3. Insert the insertion rod 1 into the regulator body from bottom to top, so that the upper end of the insertion rod 1 passes through the hole on the pressure cover 200, and the abutment 2 abuts against the lower end of the regulator body. Then, reassemble the clamping part 3 onto the upper end of the insertion rod 1 (e.g., Figure 14 (As shown).

[0064] Disassembly steps: First, lower the height of the clamping member 3 relative to the inserting rod 1 (or lower the height of the inserting rod 1 relative to the abutment member 2), so that the clamping member 3 is pressed against the pressure cover 200 (e.g., Figure 15 and Figure 16 (As shown); Next, remove the mounting bolts 300 on the lower cover 100 and remove the lower cover 100 (as shown). Figure 18 (As shown); then, gradually adjust the height of the high-pressure fastener 3 upward relative to the insert rod 1 (or gradually increase the height of the insert rod 1 upward relative to the stop 2), thereby causing the pressure cap 200 to gradually rise, so as to gradually release the elastic force of the spring 400 (as shown). Figure 19 (As shown).

[0065] Replacement steps: First, remove the sealing ring 500 from the outer periphery of the pressure cap 200, and then put the new sealing ring 500 on the pressure cap 200.

[0066] Assembly steps: First, adjust the height of the clamping member 3 downward relative to the inserting rod 1 (or adjust the height of the inserting rod 1 downward relative to the blocking member 2) so that the clamping member 3 gradually presses down the height of the cover 200, thereby gradually compressing the spring 400 until the cover 200 is completely inserted into the chamber 600. Then, assemble the lower cover 100 by using the mounting bolts 300. After that, the safe and quick disassembly and assembly tools for the gas pressure regulating equipment can be removed, and the parts removed in the preparation steps can be reassembled.

[0067] In the assembly process, the first locking member 222 is first loosened to unlock the sleeve, increasing the distance between the two clamping arms 221. This clamps the two clamping arms 221 in the appropriate position on the sleeve 21, and the through hole 2212 between the two clamping arms 221 is clamped onto the bolt post. Then, the first locking member 222 is used to re-lock the two clamping arms 221. Next, the rotating part 212 at the lower end of the sleeve 21 is rotated, causing the frustum-shaped structure at the upper end of the support part 211 to abut against the valve stem sleeve 800 (e.g., Figure 17 As shown), and the two clamping arms 221 abut against the lower end face of the flange ring 700, so that the abutment 2 abuts against the lower end of the pressure regulator body.

[0068] It should be noted that this disassembly and assembly tool is not limited to disassembling and assembling voltage regulators, but can also be used to disassemble and assemble other equipment of the same type or principle.
