[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model will be described in detail in connection with the drawings.

[0022] In connection with Figures 1-4 A pipeline eccentric explosion-proof flame arrester capable of being quickly installed comprises a fire core 1, eccentric tubes 2 symmetrically inserted at both ends of the fire core 1, and hoop tubes 3 detachably arranged at the ends of the eccentric tubes 2 connected with the fire core 1. The fire core 1 is a core component for preventing flame propagation. The eccentric tubes 2 are designed to adapt to specific pipeline installation requirements, and the connection mode of the eccentric tubes 2 with the fire core 1 is convenient for installation and maintenance. The hoop tubes 3 are used for fixing the connection position, ensuring the tightness and stability of the connection, preventing medium leakage, and ensuring the normal work of the flame arrester.

[0023] The hoop tube 3 is composed of two symmetrically arranged C-shaped tube plates 31, so that the hoop tube 3 can flexibly adapt to different connection conditions. One end of the two C-shaped tube plates 31 is movably connected through a shaft rod, which ensures the opening and closing characteristics and facilitates installation and disassembly. The other end of each C-shaped tube plate 31 is fixedly provided with a side plate 311, which provides a mounting position for the fastening bolt 32. The two side plates 311 are each provided with a mounting hole 3110, which ensures that the fastening bolt 32 can be accurately installed in the mounting hole 3110. The fastening bolt 32 is provided with a gasket and a washer at the positions connected with the side plates 311, which can reduce the wear of the side plates 311 by the fastening bolt 32 and simultaneously enhance the sealing and stability of the connection, thereby ensuring the fastening effect of the hoop tube 3 on the connection between the fire core 1 and the eccentric tube 2.

[0024] Two connecting plates 11 are fixed on the outer wall of the side plate 311 close to the fire barrier core 1, which increases the contact area of the fire barrier core 1 and the hoop seal pipe 3, and improves the stability of the connection. The two connecting plates 11 are each provided with a bolt slot 110, and a fastening bolt 32 is penetrated through the bolt slot 110, so that the fastening bolt 32 can better connect the fire barrier core 1 and the hoop seal pipe 3 together, enhance the stability of the overall structure, and ensure that the components of the fire barrier will not loosen during the working process, and ensure the fire blocking effect.

[0025] The two ends of the eccentric pipe 2 are an inlet end 21 and an outlet end 22, the size of the inlet end 21 is smaller than that of the outlet end 22, and the height of the inlet end 21 is lower than that of the outlet end 22. The difference in size and height of the inlet end 21 and the outlet end 22 of the eccentric pipe 2 is beneficial to guide the flow direction of the fluid, making the fluid flow more smoothly when passing through the fire barrier, reducing the resistance. At the same time, this special structure improves the compatibility of the fire barrier and the pipeline system, which can effectively prevent the spread of fire.

[0026] The inclination angle between the inlet end 21 and the outlet end 22 of the eccentric pipe 2 is 5°-25°, and the inclination angle between the inlet end 21 and the outlet end 22 is set in the range of 5°-25°. This angle range can further optimize the flow characteristics of the fluid, so that the fluid can flow more smoothly in the eccentric pipe 2, avoiding the occurrence of turbulence and other adverse phenomena, thereby improving the working efficiency and reliability of the fire barrier, and better playing its role of fire blocking and ensuring the safety of the pipeline; the cross section of the outlet end 22 of the eccentric pipe 2 is a convex structure, and the convex cross section structure of the outlet end 22 can better embed the hoop seal pipe 3, improve the sealing performance and stability of the connection.

[0027] The hoop seal pipe 3 is sleeved on the outer wall of the fire barrier core 1 and the outlet end 22 of the two eccentric pipes 2, which can tightly connect the fire barrier core 1 and the outlet end 22 of the eccentric pipe 2 together to form an overall structure, prevent the medium from leaking at the connection, and ensure the sealing performance of the fire barrier. At the same time, this connection method also enhances the strength of the overall structure, improves the stability of the fire barrier in the pipeline system, so that it can better withstand the pressure and possible impact in the pipeline, and ensure its long-term stable working performance.

[0028] Working principle: fluid or flame from the eccentric pipe 2 import end 21, because the import end 21 size and height is less than export end 22, and has 5 °-25 ° inclination angle, fluid or flame in the process of uphill needs to consume part of the energy to export end 22 to reach the position of firestop core 1. Fluid or flame from import end 21 to export end 22 and the contactable area of firestop core 1 increases, disperses the flame and heat, when fluid or flame enters the inside of firestop core 1, the multilayer metal net and corrugated plate in firestop core 1 further prevent the spread of flame, when fluid or flame passes out of firestop core 1 and enters the eccentric pipe 2 of another end. Because eccentric pipe 2 has a certain inclination angle, it avoids fluid or flame straight into the next section, part of fluid or flame will backflow in eccentric pipe 2, re-enter firestop core 1 and be blocked and consumed, hoop pipe 3 is connected by two C-shaped pipe plates 31 through shaft rod, side plate 311 is fixed by fastening bolt 32, gasket and washer ensure sealing and stability. The connecting plate 11 of firestop core 1 is connected with fastening bolt 32 through bolt slot 110. The convex letter-shaped structure of export end 22 of eccentric pipe 2 better realizes the embedding with hoop pipe 3 and achieves the effect of tight sealing.
