Embodiment Construction

[0014] Below in conjunction with embodiment the present invention is described in further detail, but structure of the present invention is not limited to following embodiment:

[0015] 【Example】

[0016] Such as Figure 1-3 As shown, the anti-backfire release device includes a release pipe 1, one end of the release pipe 1 is a connector 2, and the other end is a combustion head 3, and the connector 2 includes a connecting pipe 201 communicating with the release pipe 1, and the connection pipe 201 The middle section is provided with an annular protrusion 202, and a threaded pipe 203 is also sleeved on the connecting pipe 201. The outer diameter of the threaded pipe 203 is larger than the outer diameter of the annular protrusion 202, and one end of the threaded pipe 203 is provided with a blocking ring 204, the blocking ring The inner diameter of 204 is consistent with the outer diameter of the connecting pipe 201, and a rubber ring 205 is respectively arranged on both sides o...

Abstract

The invention discloses an anti-backfire vent device. The anti-backfire vent device comprises a vent pipeline (1). A connector (2) is arranged at one end of the vent pipeline (1), and a combustion head (3) is arranged at the other end of the vent pipeline (1). A fire stopper (4), a pressure regulating valve (5) and a switching valve (6) are arranged in the vent pipeline (1). A gas adding device (7) is connected to the position, close to the connector (2), of the vent pipeline (1). The vent pipeline (1) is further provided with a fire stopping and cooling device (8). The anti-backfire vent device has the advantages that the fire stopping and cooling device is arranged, and therefore heat is prevented from being transmitted to the fire stopper through a pipeline, strong wind is prevented from blowing flames to the fire stopper, and the fire stopping effect is guaranteed.

Description

technical field [0001] The invention relates to the release of natural gas transmission pipelines, in particular to an anti-backfire release device. Background technique [0002] In natural gas transmission, before maintaining a section of the pipeline, it is necessary to release the pipeline, because even after the valves on both sides of the pipeline are closed, there is still gas in the pipeline, and direct maintenance will cause the gas to leak and pollute the environment. Do release treatment, and then maintain. The release pipe is connected to this section of the pipeline, and the gas is exported for combustion. Because the pressure of the gas in the pipeline is relatively high, it will automatically flow to the release pipe. Generally, the release device will be near the combustion end. Install a flame arrester to prevent flashback, but if the burning time is too long, or the flame is blown by strong wind, the flame will be blown to the flame arrester, which will caus...
