Description

Technical Field

[0001] This utility model relates to the field of natural gas pressure stabilization pipeline technology, specifically to a high-pressure alarm device for natural gas pressure stabilization pipelines. Background Technology

[0002] Natural gas refers to all gases that exist naturally in the world, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcano gas, coalbed methane, and biogenic gas, etc.). Natural gas pressure-stabilizing pipelines are generally equipped with high-pressure alarm devices. A patent with authorization announcement number CN208566205U and titled "A High-Pressure Alarm Device for Natural Gas Pressure-Stabilizing Pipelines" includes a pipeline body, a natural gas alarm structure, and a flange. The pipeline body and the natural gas alarm structure are connected by the flange. The natural gas alarm structure includes a cylinder and a first support rod. One end of the first support rod is vertically fixed to the inner wall of the cylinder, and the other end is fixedly connected to an arc-shaped support plate. A stop is provided above the arc-shaped support plate. A collection tank is fixedly connected to the surface of the cylinder, and a U-shaped plate is provided inside the collection tank. Both ends of the U-shaped plate are fixedly connected to the surface of the cylinder. An elastic telescopic rod is fixedly connected to the lower surface of the U-shaped plate, and the end of the elastic telescopic rod away from the U-shaped plate is fixedly connected to the stop. This natural gas pressure-stabilizing pipeline high-pressure alarm device is easy to operate and can promptly detect changes in pipeline pressure, avoiding potential dangers. It provides comprehensive pipeline monitoring and can also collect natural gas, protecting the environment from natural gas pollution and preventing leaks from harming human health. However, during installation, installers pass bolts used to connect the two flanges through the through-holes in the flanges, then put nuts on the bolts and tighten them with tools. To prevent the bolts from rotating during tightening, a hand tool is needed to hold the bolt head in place, resulting in low installation efficiency. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a high-pressure alarm device for natural gas pressure stabilization pipelines.

[0004] The technical solution adopted by this utility model to solve its technical problem is a high-pressure alarm device for a natural gas pressure stabilizing pipeline, including a natural gas alarm structure. The natural gas alarm structure is fitted with two clamping sleeves. Flanges are fixed at both ends of the natural gas alarm structure. The opposing side walls of the two clamping sleeves are provided with multiple slots for the heads of bolts to be inserted. A stop block is fixed at the top of each of the two clamping sleeves. Two lifting rods are provided between the two flanges. The top of each of the two stop blocks is provided with a through hole for the bottom end of the lifting rod to pass through. A spring is fitted on each of the two lifting rods. A locking block is fixed at the bottom end of each of the two lifting rods. A slot adapted to the locking block is provided at the top of each of the two flanges.

[0005] By adopting the above technical solution, the flanges at both ends of the natural gas alarm structure are placed between the two pipe flanges. The ends of the bolts are passed through the through holes on the flanges and pipe flanges. The two lifting rods are lifted, pushing the two ferrules to move in opposite directions. After the bolt heads are inserted into the slots on the side walls of the ferrules, the two lifting rods are released. The two springs push the two clamping blocks down, and the bottom ends of the two clamping blocks are inserted into the slots at the top of the two flanges. This can prevent the ferrules from slipping. When tightening the nuts, there is no need to hold the bolt heads with a hand tool, which improves the installation efficiency.

[0006] Specifically, the natural gas alarm structure has two guide rods fixed on it, and both of the sleeves are provided with sliding grooves that are adapted to the guide rods.

[0007] By adopting the above technical solution, the sliding grooves on the guide rod and the sleeve can prevent the sleeve from rotating and causing the bolt head to be unable to be smoothly inserted into the slot on the side wall of the sleeve.

[0008] Specifically, two support mechanisms are provided between the two flanges. The support mechanism includes a base and a threaded column. The base is connected to the natural gas alarm structure. The bottom end of the base is fixed with a threaded column, and the bottom end of the threaded column is threadedly connected with a threaded sleeve.

[0009] By adopting the above technical solution, rotating the threaded sleeve can adjust the distance between the bottom end of the threaded sleeve and the ground. The bottom end of the threaded sleeve is in close contact with the ground, which can improve the stability of the natural gas alarm structure.

[0010] Specifically, the bottom end of the threaded sleeve is fixed with a support, and the support is provided with multiple mounting holes.

[0011] By adopting the above technical solution, the setting of the support and mounting hole makes it convenient to fix the support to the ground with bolts.

[0012] Specifically, the outer wall of the threaded sleeve is fixed with an anti-slip sleeve.

[0013] By adopting the above technical solution, the anti-slip sleeve can be gripped, making it easy to rotate the threaded sleeve.

[0014] The beneficial effects of this utility model are:

[0015] (1) The high-pressure alarm device for natural gas pressure stabilization pipeline described in this utility model places the flanges at both ends of the natural gas alarm structure between two pipe flanges, passes the end of the bolt through the through hole on the flange and the pipe flange, lifts the two lifting rods, pushes the two ferrules to move in opposite directions, and after the head of the bolt is inserted into the slot on the side wall of the ferrule, the two lifting rods are released, and the two springs push the two ferrules to move down. The bottom end of the two ferrules is inserted into the slot on the top of the two flanges, which can prevent the ferrules from sliding. When tightening the nut, there is no need to hold the bolt head with a tool, which improves the installation efficiency.

[0016] (2) The high-pressure alarm device for natural gas pressure stabilization pipeline described in this utility model can adjust the distance between the bottom end of the threaded sleeve and the ground by rotating the threaded sleeve. The setting of the support and the mounting hole makes it convenient to fix the support to the ground with bolts, which can improve the stability of the natural gas alarm structure.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To improve installation efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the high-pressure alarm device for a natural gas pressure stabilizing pipeline of this utility model includes a natural gas alarm structure 1, on which two clamping sleeves 2 are fitted. Flanges 3 are welded and fixed to both ends of the natural gas alarm structure 1. The opposite sidewalls of the two clamping sleeves 2 are provided with multiple slots for the heads of bolts to be inserted. A stop block 6 is welded and fixed to the top of the two clamping sleeves 2. Two lifting rods 7 are provided between the two flanges 3. The top of the two stop blocks 6 is provided with through holes for the bottom end of the lifting rods 7 to pass through. Springs 8 are fitted on the two lifting rods 7. A locking block 9 is welded and fixed to the bottom end of the two lifting rods 7. The top of the two flanges 3 is provided with a slot adapted to the locking block 9.

[0024] When in use, place the flanges 3 at both ends of the natural gas alarm structure 1 between the two pipe flanges, pass the ends of the bolts through the through holes on the flanges 3 and pipe flanges, lift the two lifting rods 7, push the two ferrules 2 to move in opposite directions, and after the bolt heads are inserted into the slots on the side walls of the ferrules 2, release the two lifting rods 7. The two springs 8 push the two locking blocks 9 down, and the bottom ends of the two locking blocks 9 are inserted into the slots at the top of the two flanges 3, which can prevent the ferrules 2 from sliding. When tightening the nuts, there is no need to hold the bolt heads with a tool, which improves the installation efficiency.

[0025] To prevent the sleeve 2 from rotating, for example, such as Figure 1 As shown, two guide rods 4 are welded and fixed on the natural gas alarm structure 1, and both of the sleeves 2 are provided with sliding grooves that are adapted to the guide rods 4.

[0026] To improve the stability of the natural gas alarm structure 1, for example, such as Figure 1 , Figure 3 As shown, two support mechanisms 5 are provided between the two flanges 3. The support mechanism 5 includes a base 50 and a threaded column 51. The base 50 is welded to the natural gas alarm structure 1. The bottom end of the base 50 is welded and fixed with the threaded column 51. The bottom end of the threaded column 51 is threadedly connected to the threaded sleeve 52.

[0027] When in use, rotating the threaded sleeve 52 can adjust the distance between the bottom end of the threaded sleeve 52 and the ground. The bottom end of the threaded sleeve 52 is in close contact with the ground, which can improve the stability of the natural gas alarm structure 1.

[0028] For ease of installation, an example is provided, such as Figure 3 As shown, a support 53 is welded and fixed to the bottom end of the threaded sleeve 52, and the support 53 is provided with multiple mounting holes.

[0029] To facilitate the rotation of the threaded sleeve 52, for example, as shown... Figure 3 As shown, the outer wall of the threaded sleeve 52 is fixed with an anti-slip sleeve 54 by an adhesive.

[0030] In use, the flanges 3 at both ends of the natural gas alarm structure 1 are placed between the two pipe flanges. The ends of the bolts are passed through the through holes on the flanges 3 and the pipe flanges. The two lifting rods 7 are lifted, which pushes the two ferrules 2 to move in opposite directions. After the bolt heads are inserted into the slots on the side walls of the ferrules 2, the two lifting rods 7 are released. The two springs 8 push the two locking blocks 9 to move down. The bottom ends of the two locking blocks 9 are inserted into the slots at the top of the two flanges 3, which can prevent the ferrules 2 from sliding. When tightening the nuts, there is no need to hold the bolt heads with a tool, which improves the installation efficiency. The natural gas alarm structure 1 is existing technology, and its specific structure and principle will not be described in detail.

[0031] By holding the anti-slip sleeve 54 and rotating the threaded sleeve 52, the distance between the bottom of the support 53 and the ground can be adjusted. The setting of the support 53 and the mounting hole makes it easy to fix the support 53 to the ground with bolts. The support mechanism 5 can support the natural gas alarm structure 1 and improve the stability of the natural gas alarm structure 1.
