Embodiment Construction
[0019] The technical characteristics of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific examples.
[0020] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 Shown: a threaded flame arrester with a liner, comprising a flame arrester inner tube 1, a fire arrester net 2, a flame arrester liner 3 and a flame arrester casing 4.
[0021] The flame arrester liner is set in the flame arrester sleeve; the flame arrester net is set in the flame arrester sleeve adjacent to the flame arrester liner; one end of the flame arrester inner tube is inserted into the flame arrester sleeve, adjacent to the fire arrester net, and the flame arrester sleeve The pipe is threaded to press and fix the fire arrester net and the flame arrester liner. The inner tube of the flame arrester is in the shape of a round tube, and one end is a ring plane; the other end is provided with the thread 5 at the upper end of the inner ...

The invention relates to a thread connection fire arresting net type fire arrester with a lining plate. The thread connection fire arresting net type fire arrester with the lining plate comprises the lining plate of the fire arrester, a sleeving pipe of the fire arrester, a fire arresting net, and an inner pipe of the fire arrester. The lining plate of the fire arrester is arranged in the sleeving pipe of the fire arrester; the fire arresting net is arranged in the sleeving pipe of the fire arrester and adjacent to the lining plate of the fire arrester, one end of the inner pipe of the fire arrester is inserted into the sleeving pipe of the fire arrester, is adjacent to the fire arresting net, and is connected with the sleeving pipe of the fire arrester in a threaded mode to compact and fix the fire arresting net and the lining plate of the fire arrester. The installation of the fire arresting net type fire arrester is simple and convenient, especially more obvious for a high altitude pipeline. The thread connection fire arresting net type fire arrester with the lining plate can be used normally in the high pressure pipeline through the lining plate of the fire arrester. Combustible gas is sent into the inner pipe of the fire arrester through a pipeline firstly, after the combustible gas goes through the fire arresting net and the lining plate of the fire arrester, and the combustible gas is sent to the downstream position through the sleeving pipe of the fire arrester. When a downstream pipeline has accidents and catches a fire, flames enter the sleeving pipe of the fire arrester through the pipeline, after the flames pass through the lining plate of the fire arrester, the flames are obstructed by the fire arresting net level by level, then the flames are weakened until extinguishment, and the safety of an upstream pipeline network is protected.
Description
technical field [0001] The invention relates to a screw-connected fire arresting net type flame arrester with a liner. Background technique [0002] The traditional flame arrester is connected with the pipeline by the flange, and the flame arrester is fixed by the flange. This kind of flame arrester has a large volume, heavy weight, and is not resistant to high pressure. It needs other accessories (bolts, gaskets, etc.) to connect with the pipeline, and it is difficult to maintain. Contents of the invention [0003] In view of the characteristics of the traditional flame arrester, such as large volume, heavy weight, not high pressure resistance, other accessories (bolts, gaskets, etc.) are required to connect with the pipeline, and the maintenance is difficult. The invention relates to a threaded fire arresting net type flame arrester with lining boards. It has the advantages of small size, light weight, high pressure resistance, convenient connection with pipelines, and...
