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
The present invention relates to a kind of gas apparatus, especially a kind of inflammable gas gas collection bag arm combustion gas spark arrester.
Background technology
During commonly used flame arrester for pipe generation tempering accident, stop up the micropore on the fusible alloy microwell plate, extinguish tempering through the heat melts fusible alloy, but because of it can not cut off source of the gas, so still there is potential safety hazard.
Summary of the invention
To above-mentioned existing problems, the present invention provides a kind of inflammable gas gas collection bag bye-pass combustion gas spark arrester, is with inner non-return device, can in time cut off air feed automatically, extinguish tempering, removes accident potential effectively.
In order to reach above purpose; The present invention takes following technical scheme; A kind of inflammable gas gas collection bag arm combustion gas spark arrester this, mainly comprise housing, spring base, spring, fusible alloy micropore cover, sealing ring, connector, it is characterized in that: also be connected with a nonreturn valve core on the said spring.
Advantage of the present invention is: the check valve of enclosure interior increases in time cut-out air feed automatically through instantaneous pressure when tempering, the accident of farthest exempting from takes place, and ensures the safety of the person and equipment.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention
1. housing 2. spring bases 3. fusible alloy micropores overlap 4. springs, 5. nonreturn valve cores
6. fixed seal ring 7. connectors 8. movable sealing circles.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Embodiment one
As shown in Figure 1; The present invention is a kind of inflammable gas gas collection bag bye-pass combustion gas spark arrester; Comprise: housing 1, spring base 2, fusible alloy micropore cover 3, spring 4, fixed seal ring 6, connector 7 and movable sealing circle 8; Be connected with a nonreturn valve core 5 on the said spring 4, spring base 2 support springs 4 and fusible alloy micropore cover 3, fixed seal ring 6 is a static seal.
Operating principle is: during normal air feed, bleed pressure overcomes the spring force of spring 4, opens nonreturn valve core 5 to appointment place air feed.When the tempering accident took place, tempering heat melts fusible alloy stopped up the micropore on the fusible alloy micropore cover 3, extinguishes tempering.The tempering heat expands housing 1 interior gas, and pressure raises, and promotes nonreturn valve core 5 and cuts off air feed with connector 7 applyings.
Embodiment two
A kind of inflammable gas gas collection bag bye-pass combustion gas spark arrester with embodiment one; Its difference is: a movable sealing circle 8 also is installed on the said nonreturn valve core 5; Movable sealing circle 8 is an intermittently used static seal; Shift to connection 1 with nonreturn valve core 5, make and fit better, shutoff is died more thorough.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
Claims (2)
1. an inflammable gas gas collection bag arm combustion gas spark arrester mainly comprises housing, spring base, spring, fusible alloy micropore cover, sealing ring, connector, it is characterized in that: also be connected with a nonreturn valve core on the said spring.
2. a kind of inflammable gas gas collection bag arm combustion gas spark arrester according to claim 1 is characterized in that: a movable sealing circle also is installed on the nonreturn valve core.
