Problems solved by technology

[0005] However, whether it is a wire mesh flame arrester or a metal plate flame arrester, the resistance loss generated during the pipeline transportation of gas is very large
Because the gas always flows through the gap structure of the flame arrester, this causes a certa

Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0023] Embodiment Taking the manual reset mechanism as an example, the flame arrester housing, cover and fire arresting core are made of aluminum.

[0024] figure 1 The state shown is that the flame arresting core 4 stagnates on both sides of the pipeline under normal conditions.

[0025] figure 2 Among them, the optical fiber 16 is fixed in the metal gasket 15, and is sealed with the upper sealing gasket 17, and one side is photosensitive and the other side is exported and introduced into the electric control mold box 2.

[0026] When there is a flame in the pipeline, the photosensitive element 10 receives the light signal and transmits it to the electric control module 2 through the optical fiber 16, and is converted into an electrical signal through the electric control module 2; 4 pops up, closes the pipeline along ...

Abstract

The invention relates to an automatic type detonation-hindered flame arrester, which belongs to the technical field of chemical engineering machinery. The automatic type detonation-hindered flame arrester is characterized in that: the flame arrester comprises a sensitization element, a control circuit, an actuating mechanism, a sliding flame retardant core mechanism, a power mechanism and a resetting mechanism, wherein the sensitization element consists of optical fibers, a metal pad and upper part and lower part sealing gaskets; an electric control mould box of the control circuit contains asilicon photodiode, a single-chip microcomputer, and a signal transmitter which is used when the resetting mechanism is manual; the single-chip microcomputer detects, receives and times electric signals from the silicon photodiode and the signal transmitter and controls the starting of external and internal electric control sticking points; the actuating mechanism is the internal and external electric control sticking points; the sliding flame retardant core mechanism consists of a flame retardant core and a flame arrestor casing; the power mechanism is a bursting power source such as a big spring; and the resetting mechanism comprises a metal chain, a fixed rotating shaft, a mobile rotating shaft and a power source. The automatic type denotation-hindered flame arrester has the advantagesthat: the flame arrester cannot only extinguish flame to realize the aim of flame retardation if the flame exists, but also have nearly zero resistance to gas if no flame exists.

Description

technical field [0001] The invention belongs to the technical field of chemical machinery and relates to a fire arresting device for preventing the deflagration of combustible gas in a pipeline. Background technique [0002] Industrial accidents caused by combustible gas explosions in pipelines occur from time to time, directly affecting normal production and personal safety. For this reason, people have studied a large number of technologies and devices to prevent and suppress combustible gas combustion explosions. Research on the combustion and explosion process of combustible gases in pipelines A relatively systematic theory has been formed, and there are many methods and technologies to suppress the combustion of combustible gas. At present, the main method is to install a flame arrester in the pipeline. The structure of the flame arrester is generally made of wire mesh or metal plate, etc., and is installed in the middle of the pipeline by flange connection, and the fla...
