Abstract
The utility model relates to a flame arrester for a pipe, which is a safety device used for preventing flame of inflammable gas and steam of inflammable liquid from spreading. The utility model has the structure that the interior of a split circular cavity formed by flanges in a butting mode is provided with a disc-shaped flame arresting core in the lateral direction; the flame arresting core is formed by a steel belt provided with transverse slots and a flat steel belt in an integral winding mode. Many triangular passages are formed on the transverse surface of a flame arresting disc, medium in the pipe can be made to normally flow through, and the flame is divided into many minute flame jets to be extinguished after entering. The utility model is widely used for a petrochemical industry system, a transporting system, a coal mine system and a shipping system.
Description
Technical field
The utility model relates to a kind of safety device, is a kind of flame arrester for pipe specifically.
Background technology
Spark arrester at present commonly used, its back-fire relief dish is made with wire netting, has plenty of the individual layer net, has plenty of multilayer, and the useful copper mesh of wire netting has plenty of with stainless (steel) wire and is piled up, and forms the back-fire relief dish.The number of plies of wire netting and mesh order number are directly connected to the back-fire relief performance.The spark arrester convection cell resistance of this structure is big, and easily stops up, and the back-fire relief performance is also poor, only is suitable for stoping low speed flame, in addition, because structural strength own is low, reasons such as decay resistance, relevant functional departments no longer recommend to use to this spark arrester of this kind.
Summary of the invention
The utility model is to provide a kind of safety device that is used for the pipeline back-fire relief, and it is easy to make, and the back-fire relief performance is good, is convenient to installation and maintenance.Its skill scheme: circular back-fire relief dish is laterally to have the steel band common coil of triangular slot to make on fire-retardant core by one deck flat strip steel and one deck, passage on the circular back-fire relief dish plane of structure is triangular in shape, the back-fire relief dish is seized on both sides by the arms fixing by procapsid and back casing, locating ring is in the back-fire relief side of facing left, retainer ring limits the position on back-fire relief dish right side, procapsid, back casing are provided with independent separately chuck and companion's thermal medium gateway.
Description of drawings
Fig. 1 is the cutaway view at the utility model axial centre place, and Fig. 2 is the vertical view of Fig. 3, and Fig. 3 is that the steel band 12 isoplanar steel bands 13 that have a triangular groove conform to schematic diagram together, the schematic diagram that Fig. 4 is two steel band circles on the fire-retardant core 4.
The specific embodiment
The utility model as shown in Figure 1, it is the cavity configuration of a split, procapsid 2 and back casing 8 be by flange butt joint, and fastening by bolt 10, in the outside of procapsid 2, back casing 8 independent chuck 9 arranged respectively, the companion's thermal medium that has separately separately imports and exports 11.It can be used on the pipeline of transporting combustible gases and crystallization need be mixed the fuel gas pipeline of heat, the import and export 11 that can companion's hot line receive companion's thermal medium.On, can prevent the medium condensation-crystallization that is transferred.Procapsid 2, back casing 8 docking section internal diameters are greater than the internal diameter at two ends, be called butt end, the both ends that internal diameter is little are called thin end, and respectively carry flange 1, back-fire relief dish 5 is to add on the fire-retardant core 4 that catch makes circle around forming by the steel band 13 of one deck flat strip steel 13 and one deck with groove at bolt, as Fig. 2, Fig. 3, shown in Figure 4, the external diameter of back-fire relief dish 5 and procapsid 2 butt end internal diameters are complementary, before back-fire relief dish 5 is filled in procapsid 2, the locating ring 3 of packing into earlier, it is encased in the procapsid 2 butt end inner chambers, is stuck in the end, inclined-plane of inwall, then back-fire relief dish 5 is filled in subsequently, and block fire-retardant dish 5 outside with a retainer ring 6 at its another side, and hold under the arm tightly together with bolt 10 by back casing 8, back-fire relief dish 5 left and right sidesing shiftings prevented.The flange 1 of the thin end of procapsid 2, back casing 8 is used for being connected usefulness with pipeline.
