Description

Quick assembly disassembly formula exhaust spark arrester device

Technical Field

The utility model belongs to the technical field of the spark arrester technique and specifically relates to a quick assembly disassembly formula exhaust spark arrester device is related to.

Background

Flame arrestors are safety devices used to prevent the spread of flames from flammable gases and flammable liquid vapors. The device for preventing the passage of a propagating flame (deflagration or detonation), which is generally installed in a conduit for transporting combustible gases, or in a ventilated tank, consists of a flame-retardant core, a flame-retardant casing and accessories.

Flame arrestors are also commonly used in pipelines for the transport of flammable gases. If flammable gases are ignited, the gas flame will propagate throughout the piping network. To prevent this risk, flame arrestors are also used. Flame arrestors may also be used on pipelines with open fire equipment to prevent backfire accidents.

The application number is 201320359229.5's patent, discloses a quick assembly disassembly formula exhaust flame arrester device, including install bin and exhaust flame arrester, the install bin inside is a cavity structures, is provided with a plurality of hold-down mechanism on the inner chamber of install bin, and exhaust flame arrester passes through hold-down mechanism movable mounting in the bottom of install bin inner chamber, hold-down mechanism includes spring, sleeve and fore-set, and hold-down mechanism fixed mounting is at the inner chamber top of install bin, and spring mounting is in telescopic section of thick bamboo, and the lower extreme of spring is connected with the end of fore-set to the top of fore-set passes the through-hole and the exhaust flame arrester contact of sleeve lower extreme. Although this kind of spark arrester is simple to operate, install bin one side is penetrating, and the gas pipeline is connected back gas with the spark arrester and can directly leaks from the install bin side, though simple to operate, but not at all practical, if want to avoid the gas to leak, need utilize the bolt again at the fixed closed chamber door of install bin opening part, so the dismouting spark arrester needs dismouting bolt again, and is very inconvenient.
