To achieve these goals, the technical scheme that invention is used is as follows：
A kind of back-fire relief net formula spark arrester of threaded connection with liner plate；Including being spark arrester liner plate, spark arrester sleeve pipe, back-fire relief
Net, spark arrester inner tube；Spark arrester liner plate is arranged in spark arrester sleeve pipe；Back-fire relief net is arranged in spark arrester sleeve pipe to be served as a contrast with spark arrester
Plate is adjacent；Spark arrester inner tube one end insertion spark arrester sleeve pipe in, it is adjacent with back-fire relief net, with spark arrester sleeve pipe be connected through a screw thread by
Back-fire relief net, spark arrester liner plate are fixed.
Described spark arrester liner plate is porous plate.
Described spark arrester sleeve pipe one end is provided with internal thread and can be used cooperatively with spark arrester inner tube external screw thread, and middle part is provided with
Annulus baffle plate, the other end can be used cooperatively provided with screw thread with the screw thread of the pipeline of required connection.
Described back-fire relief net is multiple layer metal net.
Described spark arrester inner tube one end be able to can be used cooperatively provided with screw thread with the screw thread of the pipeline of required connection, in
Portion can be used provided with external screw thread with spark arrester sleeve pipe screw-internal thread fit, and the other end is circular planes.
Described back-fire relief net, spark arrester liner plate are identical with spark arrester inner tube circular planes external diameter, less than spark arrester sleeve pipe with
The internal diameter of the pipeline of spark arrester inner tube abutting end, more than annulus baffle plate diameter in the middle part of spark arrester sleeve pipe.
All connections are using threaded connection.
The beneficial effects of the invention are as follows：A kind of back-fire relief net formula spark arrester of threaded connection with liner plate makes back-fire relief net formula back-fire relief
Size, the weight of device are greatly reduced, simple installation especially embodies on the pipeline of high-altitude and become apparent.Made by spark arrester liner plate
The present invention can normally be used in pressure duct.Fuel gas delivers to spark arrester inner tube by pipeline first, is passing through back-fire relief
Downstream is delivered to by spark arrester sleeve pipe after net, spark arrester liner plate.After accident, which occurs, for downstream line catches fire, flame passes through pipeline
Into in spark arrester sleeve pipe, after spark arrester liner plate, weakened by the layer barrier of back-fire relief stratum reticulare until extinguishing, protection upstream official website peace
Entirely.The device volume is compact, high pressure resistant, repair and maintenance convenient.
