Gas well blowout prevention ignition ball

Abstract

The invention relates to a gas well blowout prevention ignition ball which comprises a plug core (1), an insulation base (2), a base (3), a connecting body (4), a lantern ring (5), a pipe casing (6), a center pipe (7), a nut cap (8), a regulating sheet (9), a plug cove (10), an ignition ball (11), propelling charge (12), a delay device (13), an ignition head (14) and propellant powder (15), wherein the plug core (1) is connected with the insulation base (2) which is connected with the base (3), one side of the plug core (1) is connected with the ignition head (14), the base (3) is provided with the connecting body (4), the outer side of the connecting body (4) is provided with the pipe casing (6), the inner side of the connecting body (4) is provided with the delay device (13) which is provided with the lantern ring (5), the center pipe (7) is arranged on the lantern ring (5) and provided with the nut cap (8), the ignition ball (11) is arranged between the center pipe (7) and the pipecasing (6), and the regulating sheet (9) and the plug cover (10) are arranged on the top of the ignition ball (11). By adopting the invention, the safety of the operator is improved; and an ignition shrapnel continuously combusts at high temperature, has the advantages of large spreading area, high ignition efficiency and better static prevention function, and is convenient and simple in operation.

Description

technical field [0001] The invention belongs to the technical field of civilian special bombs, and in particular relates to a natural gas well blowout ignition bomb. Background technique [0002] At present, the blowout and ignition of oil and gas wells mainly use 2-inch fireworks shells purchased from the market. When using fireworks bombs to ignite, they must be ignited by an open flame, which is inconvenient to operate; fireworks bombs must be set off by multiple people (more than 5 people) at close range (not more than 30 meters from the nozzle), and the launch distance is short. Evacuation, the risk factor is high; the agent used in the fireworks bomb star is ordinary pyrotechnic agent, the burning time is short, the temperature is low, and because the fireworks bomb is set off by the operator, the launch angle and direction fluctuate greatly, and the star body is inaccurate, resulting in the ignition of natural gas. is also less likely. Contents of the invention ...
