Description

Technical Field

[0001] This invention relates to the field of natural gas flow measurement technology, and in particular to a tooling for disassembling and assembling an orifice plate and a rubber ring. Background Technology

[0002] Most natural gas extraction and transportation stations use standard orifice plate flow meters to measure natural gas flow, with the standard orifice plate being the core component. The orifice plate is a consumable part; to ensure measurement accuracy, the flow control device at the production site needs to be inspected and cleaned regularly and irregularly to promptly determine if the orifice plate is in good condition. Furthermore, as production processes change, the orifice plate opening diameter needs to be adjusted, necessitating orifice plate replacement.

[0003] Inspecting, cleaning, and replacing the orifice plate all require disassembling and assembling the orifice plate and the rubber ring, that is, inserting or removing the rubber ring from the orifice plate.

[0004] In the existing technology, manually disassembling and assembling orifice plates and rubber rings can easily injure the palm or fingers. When using tools to assist in disassembly and assembly, existing tools can easily scratch or damage the orifice plate, causing it to be scrapped and increasing the cost of production metering facilities. Summary of the Invention

[0005] To address the problems in the prior art, this application proposes a tooling for disassembling and assembling orifice plates and rubber rings. This tooling helps to avoid accidental injury to the hands or fingers of the disassembly and assembly personnel, thereby improving the safety performance of the metering facilities. It also helps to avoid scratching or damaging the orifice plate, thus preventing the orifice plate from being scrapped and avoiding increasing the cost of the metering facilities.

[0006] This invention provides a fixture for disassembling and assembling an orifice plate and a rubber ring. The fixture includes: an orifice plate holder for fixing the orifice plate; a rubber ring holder, including a clamping assembly for holding the rubber ring, a radially moving assembly for radially stretching the rubber ring, and an axially moving assembly for axially moving the rubber ring; the rubber ring holder and the orifice plate holder are connected by bearings, thereby allowing the rubber ring to move circumferentially around the orifice plate holder; and a bracket for supporting the orifice plate holder and the rubber ring holder. Using this fixture can prevent accidental injury to the hands or fingers of personnel during disassembly and assembly, improving the safety performance of the metering facility; it can also prevent scratches and damage to the orifice plate, thus avoiding the scrapping of the orifice plate and helping to avoid increasing the cost of the metering facility.

[0007] In one embodiment, the orifice plate holder includes a screw handwheel, a first fixed base, a first clamping member, a second clamping member, a second fixed base, and a crankshaft, all extending axially along the orifice plate and connected sequentially. A first sleeve is mounted on the screw handwheel, and a second sleeve is mounted on the crankshaft. The first and second sleeves connect the orifice plate holder and the support. Rotating the screw handwheel allows the first and second clamping members to clamp or release the orifice plate. This embodiment enables the orifice plate holder to clamp the orifice plate, facilitating smooth assembly and disassembly.

[0008] In one embodiment, a pin is provided on the crankshaft, which passes through the second sleeve to prevent the crankshaft from rotating. This embodiment, by using a pin, prevents crankshaft rotation, thereby preventing the orifice plate from rotating during assembly and disassembly.

[0009] In one embodiment, anti-slip pads are provided on the opposite sidewalls of the first and second clamping members, and the anti-slip pads can conform to the perforated plate. This embodiment increases the friction between the perforated plate and the first and second clamping members, preventing the perforated plate from moving or rotating during assembly and disassembly.

[0010] In one embodiment, a first bearing is provided between the first sleeve and the first fixed seat, and a second bearing is provided between the second sleeve and the second fixed seat. The rubber ring holder and the orifice plate holder are connected through the first bearing and the second bearing. With this embodiment, the first and second bearings allow the rubber ring to move circumferentially while keeping the orifice plate holder stationary, facilitating smooth assembly and disassembly.

[0011] In one embodiment, the rubber ring holder includes a horizontal arm and a first longitudinal arm and a second longitudinal arm located at both ends of the horizontal arm. The first longitudinal arm is connected to the first bearing, and the second longitudinal arm is connected to the second bearing. This embodiment facilitates circumferential rotation of the rubber ring, thereby promoting smooth assembly and disassembly.

[0012] In one embodiment, the clamping assembly includes a first wedge and a second wedge, which are axially slidable on a directional slide bar on a wedge base. A first locking pin passes through the first wedge and the wedge base, and a second locking pin passes through the second wedge and the wedge base. The first and second locking pins can clamp the rubber ring between the first and second wedges. This embodiment facilitates locking the rubber ring and allows it to move together with the clamping assembly.

[0013] In one embodiment, the radial movement assembly includes an adjusting screw, one end of which is connected to the clamping assembly, and the other end is provided with an adjusting handwheel. With this embodiment, the radial movement assembly can drive the clamping assembly to move radially via the adjusting handwheel, thereby radially stretching the rubber ring.

[0014] In one embodiment, an axial groove is provided on the cross arm. This embodiment provides sliding space for the axial sliding of the adjusting screw, which is beneficial for the axial movement of the rubber ring.

[0015] In one embodiment, the axial movement assembly includes two nuts located on the adjusting screw and a displacement sleeve located on the cross arm. The two nuts are respectively located on both sides of the cross arm. Rotating the displacement sleeve pushes the nuts, and the nuts cause the adjusting screw to slide within the groove, thereby allowing the clamping assembly to move axially under the action of the adjusting screw. This embodiment enables the axial movement of the rubber ring, facilitating smooth assembly and disassembly.

[0016] The orifice plate and rubber ring assembly / disassembly fixture provided in this application has the following advantages compared to the prior art.

[0017] 1. The orifice plate and rubber ring disassembly and assembly fixture provided by the present invention can avoid accidental injury to the palms or fingers of the disassembly and assembly personnel, thereby improving the safety performance of the metering facility; it can also avoid scratching or damaging the orifice plate, thereby avoiding the scrapping of the orifice plate and helping to avoid increasing the cost of the metering facility.

[0018] 2. The orifice plate holder can clamp the orifice plate to facilitate disassembly and assembly.

[0019] 3. The rubber ring holder can clamp the rubber ring and enable radial, axial, and circumferential movement of the rubber ring to facilitate smooth assembly and disassembly.

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, this embodiment provides a fixture for assembling and disassembling an orifice plate 26 and a rubber ring 5. The fixture includes: an orifice plate holder for fixing the orifice plate 26; a rubber ring holder including a clamping assembly for clamping the rubber ring 5, a radial moving assembly for radially stretching the rubber ring 5, and an axial moving assembly for axially moving the rubber ring 5; the rubber ring holder and the orifice plate holder are connected by a bearing, thereby enabling the rubber ring 5 to move circumferentially around the orifice plate holder; and a bracket 23 for supporting the orifice plate holder and the rubber ring holder.

[0030] The orifice plate holder can fix the orifice plate 26 axially. The axis of the orifice plate holder coincides with the axis of the orifice plate 26. The orifice plate holder can keep the orifice plate 26 stationary during the installation and removal of the rubber ring 5.

[0031] The rubber ring holder includes a clamping assembly, a radial moving assembly, and an axial moving assembly. The clamping assembly locks the rubber ring 5, allowing it to move together with the clamping assembly. The radial moving assembly drives the clamping assembly and rubber ring 5 to move radially, and the axial moving assembly drives the clamping assembly and rubber ring 5 to move axially. The rubber ring holder is connected to the orifice plate holder via bearings, enabling the clamping assembly and rubber ring 5 to move circumferentially around the orifice plate holder.

[0032] During the installation of the rubber ring 5, the orifice plate 26 is first fixed using the orifice plate holder, and the rubber ring 5 is fitted onto the orifice plate holder. Then, the rubber ring 5 is fixed using the clamping assembly. The rubber ring 5 is radially stretched by the radial movement assembly, and then the rubber ring 5 is moved circumferentially around the orifice plate holder. Next, the rubber ring 5 is axially moved using the axial movement assembly, thereby fitting the rubber ring 5 onto the orifice plate 26.

[0033] During the disassembly of the rubber ring 5, the orifice plate 26 and the rubber ring 5 are first fixed using the orifice plate holder, and then the rubber ring 5 is fixed using the clamping assembly. The rubber ring 5 is radially stretched by the radial movement assembly, and then the rubber ring 5 is moved circumferentially around the orifice plate holder. Next, the rubber ring 5 is axially moved by the axial movement assembly, thereby separating the rubber ring 5 from the orifice plate 26.

[0034] The tooling in this embodiment can axially fix the hole plate 26 and clamp and move the rubber ring 5, wherein the rubber ring 5 can move radially, axially and circumferentially, thereby assembling and disassembling the hole plate 26 and the rubber ring 5.

[0035] Since the tooling can prevent the palms or fingers of the disassembly and assembly personnel from directly contacting the orifice plate 26 or the rubber ring 5 during the disassembly and assembly process, it helps to avoid accidental injury to the palms or fingers of the disassembly and assembly personnel and improves the safety performance of the metering facility; it also helps to avoid scratching or damaging the orifice plate 26, thereby avoiding the scrapping of the orifice plate 26 and helping to avoid increasing the cost of the metering facility.

[0036] The assembly and disassembly fixtures for the orifice plate 26 and rubber ring 5 in this embodiment help to avoid accidental injury to the hands or fingers of the assembly and disassembly personnel, thereby improving the safety performance of the metering facility; they also help to avoid scratching or damaging the orifice plate 26, thereby avoiding scrapping the orifice plate 26 and avoiding increasing the cost of the metering facility.

[0037] In one implementation, such as Figure 1 and Figure 3 As shown, the orifice plate holder includes a screw handwheel 1, a first fixed seat 2, a first clamping member 3, a second clamping member 7, a second fixed seat 8, and a crankshaft 4, which extend axially along the orifice plate 26 and are connected in sequence. A first sleeve 12 is provided on the screw handwheel 1, and a second sleeve 14 is provided on the crankshaft 4. The first sleeve 12 and the second sleeve 14 are used to connect the orifice plate holder and the bracket 23. Rotating the screw handwheel 1 can clamp or release the orifice plate 26 by the first clamping member 3 and the second clamping member 7.

[0038] Loosening the screw handwheel 1 allows the first clamping member 3 and the second clamping member 7 to separate, thereby allowing the orifice plate 26 to be placed between the first clamping member 3 and the second clamping member 7. Tightening the screw handwheel 1 allows the first clamping member 3 and the second clamping member 7 to clamp the orifice plate 26.

[0039] The first fixing seat 2 and the first clamping member 3 are connected by teeth and grooves; similarly, the second fixing seat 8 and the second clamping member 7 are connected by teeth and grooves. The second fixing seat 8 is threaded for threaded connection with the screw 11.

[0040] A first sleeve 12 is provided on the screw handwheel 1, and a second sleeve 14 is provided on the crankshaft 4. The first sleeve 12 and the second sleeve 14 are used to connect the orifice plate holder and the bracket 23, so that the bracket 23 can support the orifice plate holder through the first sleeve 12 and the second sleeve 14.

[0041] The orifice plate holder of this embodiment can clamp the orifice plate 26 to facilitate assembly and disassembly.

[0042] In one implementation, such as Figure 1 and Figure 3 As shown, a pin 10 is provided on the crankshaft 4, which passes through the second sleeve 14 to prevent the crankshaft 4 from rotating.

[0043] This embodiment uses the shaft pin 10 to prevent the crankshaft 4 from rotating, thereby preventing the perforated plate 26 from rotating during disassembly and assembly.

[0044] In one implementation, such as Figure 1 and Figure 3 As shown, anti-slip pads 6 are provided on the opposite sidewalls of the first clamping member 3 and the second clamping member 7, and the anti-slip pads 6 can fit into the perforated plate 26.

[0045] The anti-slip pad 6 in this embodiment can increase the friction between the perforated plate 26 and the first clamping member 3 and the second clamping member 7, and prevent the perforated plate 26 from moving or rotating during the assembly and disassembly process.

[0046] In one implementation, such as Figures 1 to 3 As shown, a first bearing 13 is provided between the first sleeve 12 and the first fixed seat 2, and a second bearing 9 is provided between the second sleeve 14 and the second fixed seat 8. The rubber ring holder and the orifice plate holder are connected through the first bearing 13 and the second bearing 9.

[0047] In this embodiment, the first bearing 13 and the second bearing 9 enable the rubber ring 5 to move circumferentially and keep the orifice plate holder stationary, which facilitates smooth disassembly and assembly.

[0048] In one implementation, such as Figure 2 and Figure 3 As shown, the rubber ring holder includes a horizontal arm 20 and a first vertical arm 24 and a second vertical arm 25 located at both ends of the horizontal arm 20. The first vertical arm 24 is connected to the first bearing 13, and the second vertical arm 25 is connected to the second bearing 9.

[0049] The horizontal arm 20 is connected to the clamping assembly. The circumferential rotation of the first vertical arm 24 and the second vertical arm 25 can drive the horizontal arm 20 to rotate circumferentially, thereby causing the clamping assembly connected to the horizontal arm 20 to rotate circumferentially, which in turn drives the rubber ring 5 to rotate circumferentially.

[0050] This embodiment facilitates the circumferential rotation of the rubber ring 5, thereby enabling smooth disassembly and assembly.

[0051] In one implementation, such as Figure 2 and Figure 3 As shown, the clamping assembly includes a first wedge 15 and a second wedge 16. The first wedge 15 and the second wedge 16 can slide axially on the directional slide bar 17 on the wedge base 30. A first locking pin 18 passes through the first wedge 15 and the wedge base 30, and a second locking pin 29 passes through the second wedge 16 and the wedge base 30. The first locking pin 18 and the second locking pin 29 can clamp the rubber ring 5 between the first wedge 15 and the second wedge 16.

[0052] The first wedge 15 and the second wedge 16 can slide axially on the directional slide bar 17 on the wedge base 30, thereby moving away from or closer to each other to release or clamp the rubber ring 5.

[0053] In order to fix the first wedge 15 and the second wedge 16, the clamping assembly also includes a first locking pin 18 and a second locking pin 29. Locking the first locking pin 18 and the second locking pin 29 can make the first wedge 15 and the second wedge 16 clamp the rubber ring 5 and no longer slide along the directional slide bar 17.

[0054] This embodiment facilitates the locking of the rubber ring 5, allowing the rubber ring 5 to move together with the clamping assembly.

[0055] In one implementation, such as Figure 2 and Figure 3 As shown, the radial movement assembly includes an adjusting screw 19, one end of which is connected to the clamping assembly, and the other end is provided with an adjusting handwheel 22.

[0056] The radial movement component of this embodiment can drive the clamping component to move radially by adjusting the handwheel 22, thereby radially stretching the rubber ring 5.

[0057] In one implementation, such as Figure 2 and Figure 3 As shown, an axial groove 27 is provided on the cross arm 20.

[0058] The axial groove 27 in this embodiment provides sliding space for the axial sliding of the adjusting screw 19, which is beneficial to the axial movement of the rubber ring 5.

[0059] In one implementation, such as Figure 2 and Figure 3As shown, the axial movement assembly includes two nuts 28 located on the adjusting screw 19 and a displacement sleeve 21 located on the cross arm 20. The two nuts 28 are located on both sides of the cross arm 20. Rotating the displacement sleeve 21 pushes the nuts 28, and the nuts 28 drive the adjusting screw 19 to slide in the slide groove 27, so that the clamping assembly moves axially under the drive of the adjusting screw 19.

[0060] The axial movement component of this embodiment enables the rubber ring 5 to move axially, which facilitates smooth disassembly and assembly.

[0061] Example 1

[0062] like Figures 1 to 3 As shown, this embodiment provides a fixture for assembling and disassembling an orifice plate 26 and a rubber ring 5. The fixture includes: an orifice plate holder for fixing the orifice plate 26; a rubber ring holder including a clamping assembly for clamping the rubber ring 5, a radial moving assembly for radially stretching the rubber ring 5, and an axial moving assembly for axially moving the rubber ring 5; the rubber ring holder and the orifice plate holder are connected by a bearing, thereby enabling the rubber ring 5 to move circumferentially around the orifice plate holder; and a bracket 23 for supporting the orifice plate holder and the rubber ring holder.

[0063] The orifice plate holder can fix the orifice plate 26 axially. The axis of the orifice plate holder coincides with the axis of the orifice plate 26. The orifice plate holder can keep the orifice plate 26 stationary during the installation and removal of the rubber ring 5.

[0064] The rubber ring holder includes a clamping assembly, a radial moving assembly, and an axial moving assembly. The clamping assembly locks the rubber ring 5, causing it to move together with the clamping assembly. The radial moving assembly drives the clamping assembly and the rubber ring 5 to move radially, and the axial moving assembly drives the clamping assembly and the rubber ring 5 to move axially. The rubber ring holder is connected to the orifice plate holder via bearings, thereby enabling the clamping assembly and the rubber ring 5 to move circumferentially around the orifice plate holder.

[0065] During the installation of the rubber ring 5, the orifice plate 26 is first fixed using the orifice plate holder, and the rubber ring 5 is fitted onto the orifice plate holder. Then, the rubber ring 5 is fixed using the clamping assembly. The rubber ring 5 is radially stretched by the radial movement assembly, and then the rubber ring 5 is moved circumferentially around the orifice plate holder. Next, the rubber ring 5 is axially moved using the axial movement assembly, thereby fitting the rubber ring 5 onto the orifice plate 26.

[0066] During the disassembly of the rubber ring 5, the orifice plate 26 and the rubber ring 5 are first fixed using the orifice plate holder, and then the rubber ring 5 is fixed using the clamping assembly. The rubber ring 5 is radially stretched by the radial movement assembly, and then the rubber ring 5 is moved circumferentially around the orifice plate holder. Next, the rubber ring 5 is axially moved by the axial movement assembly, thereby separating the rubber ring 5 from the orifice plate 26.

[0067] The tooling in this embodiment can axially fix the hole plate 26 and clamp and move the rubber ring 5, wherein the rubber ring 5 can move radially, axially and circumferentially, thereby assembling and disassembling the hole plate 26 and the rubber ring 5.

[0068] Since the tooling can prevent the palms or fingers of the disassembly and assembly personnel from directly contacting the orifice plate 26 or the rubber ring 5 during the disassembly and assembly process, it helps to avoid accidental injury to the palms or fingers of the disassembly and assembly personnel and improves the safety performance of the metering facility; it also helps to avoid scratching or damaging the orifice plate 26, thereby avoiding the scrapping of the orifice plate 26 and helping to avoid increasing the cost of the metering facility.

[0069] The assembly and disassembly fixtures for the orifice plate 26 and the rubber ring 5 in this embodiment help to avoid accidental injury to the hands or fingers of the assembly and disassembly personnel, thereby improving the safety performance of the metering facility; they also help to avoid scratching or damaging the orifice plate 26, thereby avoiding scrapping the orifice plate 26 and avoiding increasing the cost of the metering facility.

[0070] Example 2

[0071] During the installation of the rubber ring 5, the orifice plate 26 is first fixed using the orifice plate holder, and the rubber ring 5 is fitted onto the orifice plate holder. Then, the rubber ring 5 is fixed using the clamping assembly. The rubber ring 5 is radially stretched by the radial movement assembly, and then the rubber ring 5 is moved circumferentially around the orifice plate holder. Next, the rubber ring 5 is axially moved using the axial movement assembly, thereby fitting the rubber ring 5 onto the orifice plate 26.

[0072] The process of fixing the orifice plate 26 using the orifice plate holder and fitting the rubber ring 5 onto the orifice plate holder includes the following steps. First, loosening the screw handwheel 1 allows the first clamping member 3 and the second clamping member 7 to separate. Then, the orifice plate 26 and the rubber ring 5 are placed between the first clamping member 3 and the second clamping member 7. Next, the screw handwheel 1 is tightened to clamp the orifice plate 26 between the first clamping member 3 and the second clamping member 7 and to fit the rubber ring 5 onto the orifice plate holder.

[0073] The process of securing the rubber ring 5 using the clamping assembly includes the following steps. First, the first locking pin 18 and the second locking pin 29 are removed, and the first wedge 15 and the second wedge 16 are slid along the directional slide bar 17 to separate from each other. The rubber ring 5 is then placed between the first wedge 15 and the second wedge 16, and the first wedge 15 and the second wedge 16 are slid along the directional slide bar 17 to move closer to each other until the rubber ring 5 is locked. The first locking pin 18 and the second locking pin 29 are then locked, so that the first wedge 15 and the second wedge 16 clamp the rubber ring 5 and prevent the first wedge 15 and the second wedge 16 from sliding along the directional slide bar 17.

[0074] The radial movement assembly radially stretches the rubber ring 5, which includes the following steps: Rotating the adjusting handwheel 22 causes the clamping assembly to move radially, thereby radially stretching the rubber ring 5.

[0075] The circumferentially moving rubber ring 5 includes the following steps: The horizontal arm 20 is rotated around the axis of the orifice plate holder. Under the action of the first bearing 13 and the second bearing 9, the orifice plate holder remains stationary. The first longitudinal arm 24 and the second longitudinal arm 25 drive the horizontal arm 20 to rotate, so that the radial moving assembly and the clamping assembly together drive the rubber ring 5 to move circumferentially.

[0076] The axial movement of the rubber ring 5 includes the following steps: Rotating the displacement sleeve 21 pushes the nut 28, and the nut 28 drives the adjusting screw 19 to slide within the slide groove 27, so that the clamping assembly moves axially under the drive of the adjusting screw 19, thereby driving the rubber ring 5 to move axially.

[0077] Example 3

[0078] During the disassembly of the rubber ring 5, the orifice plate 26 and the rubber ring 5 are first fixed using the orifice plate holder, and then the rubber ring 5 is fixed using the clamping assembly. The rubber ring 5 is radially stretched by the radial movement assembly, and then the rubber ring 5 is moved circumferentially around the orifice plate holder. Next, the rubber ring 5 is axially moved by the axial movement assembly, thereby separating the rubber ring 5 from the orifice plate 26.

[0079] The process of securing the perforated plate 26 and the rubber ring 5 using the perforated plate clamp includes the following steps. First, loosening the screw handwheel 1 allows the first clamping member 3 and the second clamping member 7 to separate. Then, the integrated perforated plate 26 and the rubber ring 5 are placed between the first clamping member 3 and the second clamping member 7. Next, the screw handwheel 1 is tightened to clamp the integrated perforated plate 26 and the rubber ring 5 between the first clamping member 3 and the second clamping member 7.

[0080] The process of securing the rubber ring 5 using the clamping assembly includes the following steps. First, the first locking pin 18 and the second locking pin 29 are removed, and the first wedge 15 and the second wedge 16 are slid along the directional slide bar 17 to separate from each other. The rubber ring 5 is then placed between the first wedge 15 and the second wedge 16, and the first wedge 15 and the second wedge 16 are slid along the directional slide bar 17 to move closer to each other until the rubber ring 5 is locked. The first locking pin 18 and the second locking pin 29 are then locked, so that the first wedge 15 and the second wedge 16 clamp the rubber ring 5 and prevent the first wedge 15 and the second wedge 16 from sliding along the directional slide bar 17.

[0081] The radial movement assembly radially stretches the rubber ring 5, which includes the following steps: Rotating the adjusting handwheel 22 causes the clamping assembly to move radially, thereby radially stretching the rubber ring 5.

[0082] The circumferentially moving rubber ring 5 includes the following steps: The horizontal arm 20 is rotated around the axis of the orifice plate holder. Under the action of the first bearing 13 and the second bearing 9, the orifice plate holder remains stationary. The first longitudinal arm 24 and the second longitudinal arm 25 drive the horizontal arm 20 to rotate, so that the radial moving assembly and the clamping assembly together drive the rubber ring 5 to move circumferentially.

[0083] The axial movement of the rubber ring 5 includes the following steps: Rotating the displacement sleeve 21 pushes the nut 28, and the nut 28 drives the adjusting screw 19 to slide within the slide groove 27, so that the clamping assembly moves axially under the drive of the adjusting screw 19, thereby driving the rubber ring 5 to move axially.
