Description

Technical Field

[0001] This utility model relates to the technical field of installation devices, specifically an installation device for a high-pressure gas flow meter. Background Technology

[0002] Gas flow rate calibration typically uses a standard meter comparison method. The gas flow meter to be calibrated is connected in series with a standard gas flow meter calibrated to higher precision in the same gas flow path, and the same gas flow rate is measured simultaneously. The measurement results are then compared and analyzed. This method is widely used in on-site calibration and calibration of larger flow rates. When installing an insertion flow meter online, loosen the lock nut on the instrument sensor rod, then open the ball valve, manually press the sensor rod down into the pipe, and then tighten the lock nut to complete the installation.

[0003] However, this method is only suitable for low-pressure pipeline installation and cannot be used for pipelines with pressures above 10MPa used by the company, as it is impossible to manually press the side rod down, and there are also safety hazards. Currently, there is an urgent need to develop a tool that can be used for online installation or removal of high-pressure gas flow meters. This tool would allow for the online insertion and removal of gas flow meters (on high-pressure pipelines) during production, enabling online inspection of the flow meter sensor and facilitating online comparison of high-pressure gas flow meters. Utility Model Content

[0004] The purpose of this utility model is to provide a device for installing high-pressure gas flow meters. This device solves the problems mentioned above, such as the simple structure and lack of automatic demolding function of traditional aluminum molds, the tendency of the molded product to get stuck in the forming cavity of the mold during the extrusion molding of aluminum profiles, the inconvenience of manual demolding, the time and effort required, and the reduced efficiency of the device.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a high-pressure gas flow meter installation device, comprising an installation assembly, a flow meter body being provided on one side of the installation assembly, a pipe body being provided at the lower end of the flow meter body, an installation block being fixedly connected to the top of the flow meter body, the installation assembly including a U-shaped fixing member provided on one side of the pipe body, the U-shaped fixing member matching the pipe body, a movable plate being provided above the U-shaped fixing member, a first nut being rotatably connected to the top surface of the movable plate, two sets of the first nut being provided, connecting block components being provided at both ends of the U-shaped fixing member, a first transmission threaded rod being fixedly connected to one side of the two sets of connecting block components, and the movable plate being slidably connected to the two sets of the first transmission threaded rods.

[0006] Preferably, a measuring probe rod is provided on one side of the flow meter body, and one end of the measuring probe rod extends into the interior of the pipe body.

[0007] Preferably, a first bolt is threadedly connected to one side of the movable plate, and two sets of the first bolt are provided, with both sets of the first bolt being threadedly connected to the mounting block.

[0008] Preferably, a first nut is threaded onto one side of each of the two sets of first bolts.

[0009] Preferably, a second bolt is threaded onto one side of the U-shaped fastener, and two sets of the second bolt are provided, with the two sets of second bolts respectively threaded onto the two sets of connecting block components.

[0010] Preferably, a second nut is threaded onto one side of each of the two sets of second bolts.

[0011] Preferably, the two sets of first nuts are threadedly connected to the two sets of first transmission threaded rods, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When using, the U-shaped fastener is separate from other components in the installation assembly. When it is necessary to install the flow meter body on the pipeline body, first install the U-shaped fastener separately on one side of the pipeline body. The size of the U-shaped fastener is designed according to the commonly used pipeline shell and the commonly used high-pressure pipeline size. The U-shaped fastener is then fitted onto the bottom of the pipeline body. Next, the moving plate is pre-connected to the flow meter body. The mounting block on the top of the flow meter body is fixed to one side of the moving plate by two sets of first bolts, both of which penetrate the mounting block and the moving plate. Then, two sets of first nuts are respectively fitted onto the outer circumference of the two sets of first bolts. The first nuts are rotated and pushed in to fix the mounting block and the moving plate. The entire assembly consisting of the moving plate and the flow meter body is moved above the pipeline body, with the flow meter body corresponding to the pipeline body's installation position. Simultaneously, the two sets of connecting block components correspond to the two ends of the U-shaped fastener. The flow meter body is moved closer to the pipeline body until the measuring probe rod is inserted into the mounting hole of the pipeline body. The connecting block components... The top surface of the U-shaped fastener, located at the corresponding position, is connected to the connecting block component via two sets of second bolts and two sets of second nuts. During installation, the second bolts and nuts are used for connection, and can also be used to adjust the clearance. The flowmeter body is then fixed to one side of the pipe body via the mounting assembly. The operator can simultaneously rotate two sets of first nuts, which push the moving plate towards the pipe body (vertically downward movement), thus pushing the flowmeter body downwards for insertion. The depth of the mounting block inserted into the pipe body can be adjusted according to specific needs. Two sets of first drive threaded rods act as guides. A pressure plate is designed according to the size of the thermal flowmeter head. Nuts, via screws, drive the pressure plate to reliably insert the flowmeter into the pipe. This device has a simple structure, low manufacturing cost, and reliable operation, solving the company's problem of online fault diagnosis and comparison of high-pressure gas flowmeters.

[0014] 2. When it is necessary to disassemble the flow meter body, first rotate the two sets of second nuts to remove the second nuts from the second bolt side, then remove the two sets of second bolts from the U-shaped fastener side, and then separate the U-shaped fastener from the connecting block component. The user can then disassemble the installation assembly and remove the U-shaped fastener from the pipe body. Then rotate the two sets of first nuts to disengage the first nuts from the corresponding first bolts, and then remove the two sets of first bolts. Finally, separate the installation block from the moving plate. This method of disassembling the flow meter body is relatively easy to operate, and can realize the installation or disassembly of the flow meter body. It can realize the insertion and removal of high-pressure gas flow meters during production without waiting for production to stop or contact the process to reduce pressure to deal with faults or online comparison. It can realize installation, maintenance and online comparison without production stoppage, and reduce the impact of flow meter maintenance on production. Attached Figure Description

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example

[0026] Please see Figures 1-5 A measuring probe rod 32 is provided on one side of the flow meter body 3. One end of the measuring probe rod 32 extends into the inside of the pipe body 1. A first bolt 26 is threadedly connected to one side of the moving plate 24. There are two sets of first bolts 26. Both sets of first bolts 26 are threadedly connected to the mounting block 31. A first nut 25 is threadedly connected to one side of each set of first bolts 26. A second bolt 211 is threadedly connected to one side of the U-shaped fastener 21. There are two sets of second bolts 211. The two sets of second bolts 211 are threadedly connected to two sets of connecting block components 231 respectively. A second nut 22 is threadedly connected to one side of each set of second bolts 211. The two sets of first nuts 25 are threadedly connected to two sets of first transmission threaded rods 23 respectively.

[0027] In summary: When in use, the U-shaped fastener 21 is separate from other components in the mounting assembly 2. When it is necessary to install the flow meter body 3 on the pipe body 1, first install the U-shaped fastener 21 separately on one side of the pipe body 1. The dimensions of the U-shaped fastener 21 are designed according to commonly used pipe shells and the dimensions of the U-shaped fastener 21 are designed according to commonly used high-pressure pipe dimensions (309mm, 408mm). The U-shaped fastener 21 is then fitted onto the bottom of the pipe body 1. Afterwards, the moving plate 24 is pre-installed and connected to the flow meter body 3. The mounting block 31 on the top of the flow meter body 3 is fixedly connected to the moving plate 24 by two sets of first bolts 26. On one side of the movable plate 24, two sets of first bolts 26 penetrate the mounting block 31 and the movable plate 24. Two sets of first nuts 25 are then fitted onto the outer circumference of the two sets of first bolts 26. The first nuts 25 are rotated and pushed forward, fixing the mounting block 31 and the movable plate 24 together. The integral assembly consisting of the movable plate 24 and the flowmeter body 3 is moved above the pipe body 1, with the flowmeter body 3 corresponding to the installation position of the pipe body 1. Simultaneously, the two sets of connecting block components 231 correspond to the two ends of the U-shaped fixing piece 21. The flowmeter body 3 is moved closer to the pipe body 1 until the measuring probe rod 32 is inserted into the pipe body 1. Inside the mounting hole, the connecting block component 231 rests on the top surface of the corresponding end of the U-shaped fixing component 21. The U-shaped fixing component 21 and the connecting block component 231 are connected by two sets of second bolts 211 and two sets of second nuts 22. During installation and use, the second bolts 211 and second nuts 22 are used for connection, which also allows for adjustment of the clearance. The flowmeter body 3 is then fixedly installed on one side of the pipe body 1 via the mounting assembly 2. The operator can also simultaneously rotate the two sets of first nuts 25. Rotating the two sets of first nuts 25 pushes the flowmeter forward, causing the moving plate 24 to move closer to the pipe body 1. The moving plate 24 moves vertically downwards, pushing the flow meter body 3 downwards to achieve insertion installation. The depth of the installation block 31 inserted into the pipe body 1 can be adjusted according to specific needs. Two sets of first transmission threaded rods 23 serve as guides. The first transmission threaded rods 23 installed on both sides of the U-shaped fixing piece 21 are two 60cm threaded rods. A pressure plate is designed according to the size of the thermal flow meter head. A nut drives the pressure plate through the threaded rods to reliably insert the flow meter downwards into the pipe. This device has a simple structure, low manufacturing cost, and reliable operation, solving the company's problems in online fault diagnosis and online comparison of flow meters.

[0028] When it is necessary to disassemble the flow meter body 3, first rotate the two sets of second nuts 22 to remove the second nuts 22 from the side of the second bolt 211. Then, remove the two sets of second bolts 211 from the side of the U-shaped fastener 21. Then, separate the U-shaped fastener 21 from the connecting block component 231. The user can then disassemble the installation component 2 and remove the U-shaped fastener 21 from the pipe body 1. Then, rotate the two sets of first nuts 25 to disengage the first nuts 25 from the corresponding first bolts 26. Then, remove the two sets of first bolts 26 and separate the installation block 31 from the moving plate 24. This method of disassembling the flow meter body 3 is relatively easy to operate and can realize the installation or disassembly of the flow meter body 3. The flow meter can be plugged and unplugged during production without waiting for production to stop or contact the process to reduce pressure to deal with the fault or online comparison. This enables installation, maintenance and online comparison without production stoppage, reducing the impact on production caused by flow meter maintenance.
