Abstract
The utility model discloses a drawer type flame arrester which comprises a shell, wherein the shell is composed of an upper flange and a lower flange; a flame-arresting cavity is arranged between the upper flange and the lower flange; a gland is arranged outside the flame-arresting cavity; the upper flange is provided with an air inlet; the lower flange is provided with an air outlet; the air inlet is provided with an explosion-proof film; an interlayer material is arranged in the flame-arresting cavity; gravel is distributed above the interlayer material in the flame-arresting cavity; a flame-arresting core is distributed below the interlayer material in the flame-arresting cavity; and the flame-arresting core is defined by a steel wire mesh and fixed in the flame-arresting cavity. According to the utility model, the interlayer material is arranged in the flame-arresting cavity, so that the flame-arresting cavity is less prone to shock deformation under the action of high-pressure airflow in the pipeline, is favorable in stability and flame arresting performance, and protects the flame-arresting core. In the process of overhauling or replacing a flame-arresting component, the flame-arresting component can be taken out by simply detaching fasteners, so that operations such as on-line cleaning, replacement and the like can be realized.
Description
Technical field
The utility model relates to a kind of spark arrester, relates in particular to a kind of drawer type spark arrester.
Background technology
Spark arrester is that a kind of external flame that prevents is scurried into the equipment that there is flammable explosive gas or the element of pipeline, utilize wavy metal dish slit gap flame to be had the extinguishing action principle manufactures and designs, spark arrester is connected with pipeline by flange, must remove whole spark arrester from pipeline when changing the back-fire relief element.Therefore, need provide a kind of new technology to solve the problems referred to above.
The utility model content
The purpose of this utility model provides that a kind of back-fire relief performance is good, the drawer type spark arrester of easy accessibility.
The technical solution adopted in the utility model is:
The drawer type spark arrester, comprise housing, described housing is made of upper and lower flange, be provided with the back-fire relief cavity between the described upper and lower flange, described back-fire relief cavity is provided with gland outward, have air inlet on the described upper flange, have the gas outlet on the described lower flange, described air inlet place is provided with rupture pressure disc, be provided with the interlayer filler in the described back-fire relief cavity, be furnished with gravel in the back-fire relief cavity of described interlayer filler top, be furnished with fire-retardant core in the back-fire relief cavity of described interlayer filler below, described fire-retardant core is surrounded by steel wire and is fixed in the back-fire relief cavity.
Described gland is fixed on the back-fire relief cavity by securing member.
Described back-fire relief cavity is provided with safety net outward.
Described steel wire surrounds is shaped as cone.
The utility model has the advantages that: be provided with the interlayer filler in the back-fire relief cavity, be difficult for by pipeline inner high voltage gas shock distortion, good stability, the protection fire-retardant core, the back-fire relief performance is good; When the back-fire relief element was changed in maintenance, only need pull down securing member just can take out the back-fire relief element, realized work such as on-line cleaning, replacing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
