Description

TECHNICAL FIELD

[0001] The utility model relates to natural gas pipeline protection technical field especially relates to a natural gas transportation pipe protection device. BACKGROUND

[0002] As the core carrier of energy transmission network, natural gas transportation pipe undertakes the heavy responsibility of safely and efficiently transporting natural gas from the mining site to the end user, and its reliability directly affects the stability and security of energy supply. In industrial, commercial and residential gas scenarios, natural gas transportation pipe needs to adapt to complex geographical environment and climate conditions, and faces multiple risks such as corrosion, mechanical impact and vibration. For example, the pressure pulsation generated when high-pressure gas flow passes through the regulating valve may cause pipe resonance, leading to structural fatigue damage; and the control valve, as a key component for regulating gas flow, is easily exposed to high-pressure and high-frequency operating environment for a long time, which may cause sealing failure and valve piece rupture.

[0003] At present, the traditional natural gas transportation pipe protection device mostly adopts rigid fixation or simple coating structure, which is difficult to effectively cope with the dynamic stress change in the transportation process. For example, some devices reduce impact by external clamping or buffering materials, but do not solve the loosening problem caused by displacement at the pipe connection; another scheme removes impurities through a filtering mechanism, but lacks support for the overall stability of the pipe. In addition, as a vulnerable component, the control valve usually relies on an independent protective cover or reinforcing structure for protection, without forming a coordinated protection system with the transportation pipe body, so that external impact may still be transmitted to the control valve through the pipe, causing functional failure, which makes the natural gas transportation pipe face safety hazards in long-term operation. Therefore, we propose a natural gas transportation pipe protection device to solve the above problems. UTILITY MODEL CONTENT

[0025] As shown in Figure 1 The two limiting ring blocks 3 are symmetrically arranged on the two sides of the control valve 2.

[0026] Further description, such design makes the stress on both sides of the control valve 2 more uniform, can effectively protect the control valve 2 and the connecting part between the control valve 2 and the transportation pipe body 1, avoid the damage of the control valve 2 or the leakage of the connecting part due to the excessive unilateral stress, and improve the stability and reliability of the whole natural gas transportation pipe system.

[0027] As shown in Figure 1 The outer side wall of the double-headed threaded bolt 5 is provided with two external threads matched with the limiting nut 6, and the external threads on the adjacent double-headed threaded bolts 5 are threadedly connected with the inner side wall of the threaded groove.

[0028] Further description, this design is convenient for installation and disassembly, and at the same time, the fastening degree of the double-headed threaded bolt 5 can be adjusted by tightening the limiting nut 6 to adapt to different transportation working conditions and fixing requirements, and ensure the effectiveness of the protection device.

[0029] As Figure 2 shown, a plurality of limiting holes 4 are arranged in a ring array on the outer wall of the limiting ring block 3, with the axis of the limiting ring block 3 as the array center.

[0030] Further explanation, this design makes the distribution of the double-headed threaded bolt 5 more uniform, can constrain and fix the transport pipe body 1 from multiple directions, improve the stability and balance of the protection device, and better resist external force from different directions.

[0031] As Figure 1 and Figure 3 shown, the control valve 2 body outer wall is fixedly installed with a reinforcing ring block 8, a plurality of fixing holes 9 are formed in the outer wall of the reinforcing ring block 8, and the outer wall of the double-headed threaded bolt 5 is slidably connected with the inner wall of the fixing hole 9.

[0033] As Figure 2 and Figure 3 shown, the number of limiting holes 4 is the same as the number of fixing holes 9.

[0034] Further explanation, this design ensures that the double-headed threaded bolt 5 is more balanced and stable when connecting the limiting ring block 3 and the reinforcing ring block 8, so that the protection mechanism protects the transport pipe body 1 and the control valve 2 more comprehensively and effectively, and avoids the situation that local stress is uneven due to inconsistent number of connection points.

[0035] The utility model can be described by the following operation mode:

[0036] Install the limiting ring block 3: two limiting ring blocks 3 are respectively fixedly sleeved on the outer wall of the transport pipe body 1, and the two limiting ring blocks 3 are symmetrically arranged on the two sides of the control valve 2, and each limiting ring block 3 is stably connected with the outer wall of the transport pipe body 1 through a plurality of reinforcing ribs 7, and the reinforcing rib 7 can enhance the connection strength between the limiting ring block 3 and the transport pipe body 1, and guarantee the stability of the entire protection device installation.

After the double-end threaded bolt 5 passes through the limiting hole 4 and the fixing hole 9, the limiting nut 6 is threaded on both ends of the double-end threaded bolt 5, respectively. By rotating the limiting nut 6, the limiting nut 6 is gradually tightened by the thread cooperation between the limiting nut 6 and the double-end threaded bolt 5.

[0040] During this process, the tightening degree of the limiting nut 6 can be adjusted according to the actual transportation conditions and the requirements for fixing the transportation pipe body 1, so that the double-end threaded bolt 5 can properly constrain and fix the transportation pipe body 1, limit the shaking and displacement of the transportation pipe body 1, and thus realize the protection function of the natural gas transportation pipe.
