Abstract
The invention relates to a flame arrester based on inert gas. The flame arrester comprises a base body, an inert gas storage bottle and a gas guiding pipe. A main gas guiding channel, at least one communication gas guiding channel, sealing gas channels, a flame arresting sliding block, a pressure control valve and reset springs are arranged in the base body. The axis of the main gas guiding channel and the axis of the base body are coaxial, the flame arresting sliding block is located in the main gas guiding channel and slidably connected with the main gas guiding channel, and the flame arresting sliding block is connected with the inner walls of the main gas guiding channel through the reset springs. The parts, located at the two ends of the flame arresting sliding block, of the main gas guiding channel communicate through the communication gas guiding channels. Each communication gas guiding channel is additionally provided with one sealing gas channel and communicates with the gas guiding pipe through the corresponding sealing gas channel. The gas guiding pipe is further connected with the inert gas storage bottle and provided with the pressure control valve. The gas channel is blocked and isolated in a mechanical mode, while the purpose of arresting flames is achieved, flame retardance is further conducted by filling the gas channel with inert gas, and therefore flame arresting efficiency and stability of the flame arrester are greatly improved.
Description
Technical field
The present invention relates to a kind of spark arrester based on noble gas, belong to spark arrester equipment technical field.
Background technology
At present when carrying out the article such as metal are cut, combustion gas cutting torch is mainly used to cut,
Use middle discovery, all kinds of combustion gas all to also exist and higher alter fire rate, thus show as on cutting torch when interruption is cut
During torch fuel gas supply, easily there is combustion gas tempering phenomenon, as supply air line can not be blocked timely and effectively, anti-
Only tempering phenomenon occurs, and will result directly in the tempering of whole feeding pneumatic, causes combustion gas to occur the most quick-fried time serious
Fried, have a strong impact on use safety, in order to overcome this problem, the most conventional method is at cutting torch and source of the gas
Between pipeline on set special spark arrester, and current spark arrester is mainly by compression spring and seal structure
Part carries out Purely mechanical sealing structure and realizes to isolate between fuel gas pipeline and cutting torch, therefore along with sealing
The situations such as part abrasion occur, the phenomenon that spark arrester back-fire relief efficiency declines or lost efficacy easily occur, thus threaten use
Safety, it is therefore desirable to develop a kind of novel spark arrester equipment and easily meet the needs used.
Summary of the invention
For not enough present on prior art, the present invention provides a kind of spark arrester based on noble gas,
This new structure advantages of simple, reasonable in design, carrying out blocking isolation to combustion gas road by purely mechanic mode,
Reach the purpose of back-fire relief simultaneously, separately by noble gas, combustion gas road be filled with, carry out fire-retardant further,
Thus greatly improve back-fire relief efficiency and the back-fire relief stability of spark arrester.
To achieve these goals, the present invention is to realize by the following technical solutions:
A kind of spark arrester based on noble gas, including matrix, noble gas gas bomb and airway, matrix
Inside set leading air flue, connection airtube, seal air flue, back-fire relief slide block, pressure-control valve and back-moving spring,
Leading air flue is distributed with matrix axis coaxle, and back-fire relief slide block is positioned at leading air flue and is cut off by leading air flue,
Back-fire relief slide block is slidably connected with leading air flue, and is connected with leading air flue inwall by back-moving spring, and connection is led
Air flue at least one, and by connection airtube, the leading air flue at back-fire relief slide block two ends is connected, connect inducing QI
Road air inlet offsets with the back-fire relief slide block side being under reset state, and connection airtube separately sets blanket gas
Road, and connect with airway by sealing air flue, airway is separately connected with noble gas gas bomb, airway
On separately set pressure-control valve.
Further, described back-fire relief slide block and leading air flue contact surface set at least one Packing spring.
Further, described outer surface of matrix separately sets puigging.
This new structure advantages of simple, reasonable in design, by purely mechanic mode combustion gas road blocked every
From, reach the purpose of back-fire relief simultaneously, separately by noble gas, combustion gas road is filled with, hinders further
Combustion, thus greatly improve back-fire relief efficiency and the back-fire relief stability of spark arrester.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the accompanying drawings with detailed description of the invention；
Fig. 1 is this new structure schematic diagram.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with detailed description of the invention, the present invention is expanded on further.

2 and airway 3, set in matrix leading air flue 4, connection airtube 5, seal air flue 6, back-fire relief slide block 7,
Pressure-control valve 8 and back-moving spring 9, leading air flue 4 is distributed with matrix 1 axis coaxle, back-fire relief slide block 7
Being positioned at leading air flue 4 and cut off by leading air flue 4, back-fire relief slide block 7 is slidably connected with leading air flue 4,
And be connected with leading air flue 4 inwall by back-moving spring 9.
In the present embodiment, described connection airtube 5 at least one, and by connection airtube 5 by back-fire relief
The leading air flue 4 at slide block 7 two ends connects, connection airtube 5 air inlet and the back-fire relief being under reset state
Slide block 7 side offsets, and connection airtube 5 separately sets sealing air flue 6, and by sealing air flue 6 and inducing QI
Pipe 3 connects, and airway 3 is separately connected with noble gas gas bomb 2, and airway 3 separately sets pressure-control valve
8。
In the present embodiment, described back-fire relief slide block 7 sets at least one sealing bullet on leading air flue 4 contact surface
Spring 9, matrix 1 outer surface separately sets puigging 10.
This new structure advantages of simple, reasonable in design, by purely mechanic mode combustion gas road blocked every
From, reach the purpose of back-fire relief simultaneously, separately by noble gas, combustion gas road is filled with, hinders further
Combustion, thus greatly improve back-fire relief efficiency and the back-fire relief stability of spark arrester.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The industry
