Problems solved by technology

Although a gas pipeline fireproof barrier device announced by the authorized announcement number CN204910557U is designed with a backfire-proof structure, its reliability is poor, because no matter from which end a fire or explosion accident occurs, there is only one fireproof or explosion-proof opportunity. If the fire barrier device breaks down and a fire accident happens again, the harm caused can be imagined

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, a gas pipeline double fireproof and explosion-proof blocking device and blocking method, the structure of the device includes a gas pipeline 1, a fire retardant pipeline 2, a flame sensor 3, a wire 4, a controller 5, an electromagnet 6, and an electromagnetic coil 7. Blocking baffle 8, blocking valve 10, baffle groove 13, the fire retardant pipeline 2 is arranged inside the gas pipeline 1, and the flame sensor 3 is arranged on the inner wall of the gas pipeline 1 outside the fire retardant pipeline 2, so The controller 5 is connected to the flame sensor 3 through the wire 4, the electromagnetic coil 7 is connected to the controller 5, the electromagnetic coil 7 is surrounded by the electromagnet 6, and the electromagnet 6 is arranged on the outer wall of the gas pipeline 1. The blocking baffle 8 is connected to...

Abstract

The invention discloses a double fireproof and explosion-proof blocking device and blocking method for gas pipelines, which relate to the field of fireproof and explosion-proof gas pipelines. Electromagnetic coil, blocking baffle, blocking valve, baffle slot. When a fire or explosion occurs in the gas pipeline, after the flame sensor detects the flame signal, it transmits the signal to the controller through the wire, and the controller controls the power supply to stop energizing the left electromagnetic coil. Finally, it will block the transportation of gas in the gas pipeline. Even when the blocking baffle cannot work normally due to a fault, when the flame of a fire or explosion passes through the fire-stopping pipelines on the left and right sides, due to the wall effect of the small tube in the fire-stopping pipeline , will hinder the spread of the flame, and then achieve the double function of fire and explosion protection. It also has the ability to prevent tempering.

Description

technical field [0001] The invention relates to the field of fire prevention and explosion prevention of gas pipelines, in particular to a double fireproof and explosion-proof blocking device and a blocking method for gas pipelines. Background technique [0002] With the continuous adjustment of my country's energy structure, the utilization of gas is also increasing. Gas is transported through gas pipelines. During the transportation process, the biggest safety hazards are fire and explosion. In recent years, there have been many gas pipeline fires and explosion accidents in our country, causing casualties and property losses. [0003] At present, my country's fire and explosion protection technology for gas pipelines is not mature enough, mainly reflected in the low reliability and poor anti-backfire ability. For example, the quick blocking device installed in the inflammable and explosive gas delivery pipeline announced by the authorized announcement number CN201680110U...
