Abstract
The utility model discloses a gravel flame arrester which comprises a shell and a flame arresting element; the shell is of a cylindrical structure, and two ends of the shell are provided with flange disks; the inner cavity of the shell is provided with the flame arresting element consisting of a solid material which can enable gases to pass through and is provided with a plurality of channels or seams; and one end of the shell is connected with a seal cover with a channel through a flange. The gravel flame arrester provided by the utility model has the beneficial effects that the gravel flame arrester is reasonable in structure, is light in weight, is corrosion resistant, and has a good flame arresting performance; and a flame arrester core adopts stainless steel materials, is corrosion resistant, and is easy to clean.
Description
Technical field
The utility model relates to a kind of pipeline fire retardant device, particularly a kind of gravel spark arrester.
Background technology
Gravel spark arrester (having another name called flame damper), the effect of spark arrester is to prevent that external flame from scurrying in the equipment that has flammable explosive gas, the pipeline or stop flame to spread at equipment, pipeline enclosure, indispensable in the safety protection equipment, but the back-fire relief element Fire resistances of spark arrester of the prior art also reaches, and has certain technological deficiency.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of gravel spark arrester.To achieve these goals, the technical scheme that its technical problem that solves the utility model adopts is: the gravel spark arrester, comprise housing, the back-fire relief element, described housing is the cylindrical structural that two ends are provided with ring flange, be provided with the back-fire relief element at described housing inner chamber, described back-fire relief element is by can being formed by solid material gas and that have some passages or slit, and described housing one end is connected with seal cover with passage by flange.
Tiny through-hole diameter on the described back-fire relief element is between 0.1-0.2mm.
Described case material is impact resistance cast steel.
The beneficial effects of the utility model: gravel spark arrester of the present utility model is rational in infrastructure, lightweight, corrosion-resistant, and Fire resistances is fine, and the spark arrester fuse adopts stainless steel material, and corrosion-resistant easy is in cleaning.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
