Technical Field

[0001] The utility model belongs to the technical field of pipeline protection, in particular to a safety protection component for connecting a chemical pipeline. Background Art

[0002] In the chemical industry, piping systems are crucial for transporting a variety of chemicals and fluids. However, due to the corrosive, toxic, and high-pressure nature of these chemical media, the safety of these piping systems is paramount. Pipeline joints, in particular, are prone to leaks due to their complex structures and susceptibility to external forces. Once a leak occurs, it not only causes serious environmental pollution but also threatens the safety and health of workers.

[0003] Traditional pipe connection methods often fail to meet the requirements for high sealing and strength. For example, flange connections, while convenient, offer poor sealing. Welding, while providing good sealing, is complex and difficult to disassemble. Therefore, a new type of pipe connection protection device is needed that ensures excellent sealing performance while providing sufficient structural strength.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0030] See also Figure 1-5 As shown, the present invention is a safety protection assembly for chemical pipeline connection. It comprises two protective isolation ring plates 1 welded to the pipes on either side of the chemical pipeline connection. A pair of fully sealed protective covers 2 are mounted on the two protective isolation ring plates 1, which are connected together by a number of bolts and nuts. The outer diameter of the protective isolation ring plates 1 is larger than the maximum outer diameter of the chemical pipeline connection. A rubber sealing ring 3 is provided between the outer annular surface of the protective isolation ring plates 1 and the protective covers 2.

[0031] The protective isolation ring plate 1 comprises two semicircular ring plates 11. The two semicircular ring plates 11 are butt-welded and polished on the outer wall of the chemical pipeline to form the protective isolation ring plate 1, and the semicircular ring plates 11 are welded to the outer wall of the chemical pipeline.

[0032] The utility model welds a protective isolation ring plate 1 with a straight drop larger than the maximum outer diameter of the joint on the pipes on both sides of the chemical pipeline joint, and seals a pair of protective covers 2 on the two protective isolation ring plates 1. On the one hand, the chemical pipeline connection is reinforced, and on the other hand, the leaked gas is sealed in the closed cover, thereby maximally preventing the leakage of harmful gases in the chemical pipeline into the atmosphere, thereby effectively ensuring the operation of the chemical pipeline.

[0033] To enhance the seal at the connection between the semicircular ring plate 11 and the protective cover 2, the outer surface of the semicircular ring plate 11 is provided with a plurality of semicircular grooves 12 arranged along its surface. The provision of these semicircular grooves 12, combined with the rubber sealing ring 3, can form an isolation seal for multiple annular cavities, effectively ensuring the seal between the protective isolation ring plate 1 and the protective cover 2.

[0034] The protective cover 2 specifically includes a rectangular trough body 21. Semi-circular slats 22 are symmetrically fixed through one opposite side wall of the rectangular trough body 21. The inner ring surface of the semi-circular slats 22 is provided with an arc groove 23 that cooperates with the protective isolation ring plate 1. A pair of U-shaped slats 24 are fixed to the outer wall of the rectangular trough body 21. The upper surface of the U-shaped slats 24 is flush with the open end surface of the rectangular trough body 21, and the two ends of the U-shaped slats 24 are connected to the two semi-circular slats 22 as a whole. The U-shaped slats 24 expand the area of ​​the connecting end surface of the protective cover 2, which is conducive to sealing. A number of circular through holes 25 are provided on the U-shaped slats 24. After the two protective covers 2 are butt-jointed and sealed, a sealed cavity is formed at the connection of the chemical pipeline. On the one hand, the structural stability of the connection end of the chemical pipeline is improved, and on the other hand, harmful gases leaking from the chemical pipeline joint are prevented from leaking into the atmosphere.

[0035] To facilitate regular leak detection of chemical pipeline joints protected by protective cover 2, a threaded through-hole 26 is provided on one side of the rectangular trough 21. A bolt plug 4 is threadedly connected to threaded through-hole 26. For subsequent regular inspections, simply remove bolt plug 4 and insert the detector's sensor head through threaded through-hole 26 into the interior of protective cover 2 for testing. The presence of bolt plug 4 facilitates leak detection of chemical pipeline joints protected by protective cover 2.

[0036] In order to further reinforce the structure of the chemical pipeline connection end by lifting the protective cover 2, a number of U-shaped reinforcing ribs 27 are fixed to the inner bottom surface of the rectangular trough 21 and the inner side surfaces of the two walls where the two semi-circular ring strips 22 are installed.

[0037] In order to ensure the sealing between the two protective covers 2 as much as possible, a sealing rubber ring layer is provided between the two protective covers 2.
