Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to a fireproof net device at the end of a small-diameter gas detection tube. Background Technology

[0002] Liquid cargo ships must be equipped with exhaust gas sampling devices that use suction for gas detection. The end of this pipe must be located in an open, safe area of ​​the ship, and a fireproof mesh must be installed at the end. The diameter of this exhaust gas pipe is typically 10-12 mm. According to the existing ship standard CB604-93 "Fireproof Mesh for Air Pipes in Oil Tanks," the minimum applicable pipe diameter is DN80, which is not suitable for fireproof mesh devices compatible with pipes with an outer diameter of 10-12 mm. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a fireproof mesh device at the end of a small-diameter gas detection tube.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fireproof net device for the end of a small-diameter gas detection tube includes a fireproof net base and an end fireproof net assembly. The fireproof net base and the end fireproof net assembly are detachably connected, and the fireproof net base is detachably connected to the end of the gas detection tube.

[0006] Furthermore, the fireproof mesh base includes a threaded welding seat, which is a hollow structure, and its two ends are detachably connected to the end of the gas detection tube and the end fireproof mesh assembly, respectively.

[0007] Furthermore, the end fireproof net assembly includes a fireproof net cover with an open end face, one end of which is fixed to a cover base plate. Multiple through holes are evenly distributed on the circumferential sidewall of the fireproof net cover and the cover base plate. Fireproof net is laid on the inner sidewall of the fireproof net cover. The end of the fireproof net cover away from the cover base plate is detachably connected to the threaded welding seat.

[0008] Furthermore, a base flange is fixed on the outer wall of one end of the threaded welding seat, and a fireproof mesh cover flange is fixed on the outer wall of one end of the fireproof mesh cover. The threaded welding seat and the fireproof mesh cover are detachably connected through the base flange and the fireproof mesh cover flange.

[0009] Furthermore, the fireproof mesh is a stainless steel fireproof mesh, which is spot-welded to the inner wall of the fireproof mesh cover.

[0010] Furthermore, the threaded welding seat is detachably connected to the end of the gas detection tube via a compression fitting end straight pipe connector.

[0011] During installation, the fireproof mesh device at the end of the small-diameter gas detection tube of this utility model is connected to the gas detection tube via an end clamp. The manufacturing materials are very simple, and various small-diameter venting tubes can be adapted by modifying the specifications of the threaded seat and the size of the cover.
