Problems solved by technology

[0002] When a tempering accident occurs in the commonly used pipeline flame arrester, the fusible alloy is melted by heat to block the micropores on the fusible alloy microporous plate, and the tempering is extinguished, but because it cannot cut off the gas source, there are still potential safety hazards

Embodiment 1

[0011] Such as figure 1 As shown, the present invention is a gas flame arrester for a branch pipeline of a flammable gas gas collection package, comprising: a housing 1, a spring seat 2, a fusible alloy microhole sleeve 3, a spring 4, a fixed sealing ring 6, a connector 7 and The movable sealing ring 8 is connected with a one-way valve core 5 on the spring 4, the spring seat 2 supports the spring 4 and the fusible alloy microhole sleeve 3, and the fixed sealing ring 6 is a static seal.

[0012] The action principle is: when the air is supplied normally, the pressure of the air source overcomes the spring force of the spring 4, and the one-way valve core 5 is opened to supply air to the designated place. When a tempering accident occurs, the heat of tempering melts the fusible alloy to block the micropores on the fusible alloy microporous sleeve 3, and the tempering is extinguished. The tempering heat causes the gas in the housing 1 to expand and the pressure to rise, pushing ...

Embodiment 2

[0014] It is the same as the gas flame arrester of the branch pipeline of the flammable gas gas collecting bag in the first embodiment, the difference is that: the check valve core 5 is also equipped with a movable sealing ring 8, and the movable sealing ring 8 is an intermittently working Static sealing, moving to connection 1 together with the one-way valve core 5, so that the fit is better, and the sealing and air shutoff are more thorough.

Abstract

The invention relates to a branch fuel gas fire arrestor for an inflammable gas collecting bag. The branch fuel gas fire arrestor mainly comprises a shell, a spring seat, a spring, a fusible alloy micro-pore sleeve, a sealing ring and a connector, and is characterized in that: the spring is connected with a one way valve. The branch fuel gas fire arrestor has the advantages that: during tempering of the internal one-way device, a pressure is increased momentarily and gas supply is cut off automatically, so that accidents can be prevented to the maximum extent, and the safety of human bodies and equipment is ensured.

Description

technical field [0001] The invention relates to gas equipment, in particular to a gas flame arrester for branch pipes of a flammable gas gas collection package. Background technique [0002] When a flashback accident occurs in the commonly used pipeline flame arrester, the fusible alloy is melted by heat to block the micropores on the fusible alloy microporous plate and the flashback is extinguished. However, because the gas source cannot be cut off, there is still a potential safety hazard. Contents of the invention [0003] In view of the above existing problems, the present invention provides a gas flame arrester for the branch pipeline of the flammable gas gas collection package, with an internal one-way device, which can automatically cut off the gas supply in time, extinguish the backfire, and effectively eliminate hidden dangers of accidents. [0004] In order to achieve the above objectives, the present invention adopts the following technical solutions, a gas flam...
