Abstract
The invention discloses a kind of gas pipeline self closing devices to be gushed, including the first gas pipeline, the second gas pipeline, what is sealed between first gas pipeline and the second gas pipeline is socketed with one section of casing, elastic slice is equipped at first gas pipeline port, elastic slice lower surface end is connected with tube wall below the first gas pipeline port, the elastic slice upper surface be connected with valve for be closed the first gas pipeline, the angle a at an acute angle between elastic slice lower surface extended line and upper surface.When pipeline normal operation, the thrust for the combustion gas that the angle a bears the valve is less than the elastic force of the elastic slice, keeps it turned on valve；When pipeline is gushed, the thrust for the combustion gas that the angle a bears the valve is greater than the elastic force of the elastic slice, and valve is closed at once.The material of the valve is soft iron.First gas pipeline is suspended below magnet.The present invention is swift in response, effect stability.
Description
Technical field
The present invention relates to a kind of device for shutting down pipeline, especially a kind of gas pipeline self closing device to be gushed.
Background technique
When the terminal valve of gas pipeline is surprisingly damaged, combustion gas largely can gush out, no one of prior art
Conveniently device or method prevent combustion gas and gush, and are typically necessary and find main gas valve and be turned off manually.And close main valve
The time is needed, combustion gas continues to spray and let out during this, and scene diffuses a large amount of combustion gas, if meeting open fire again, danger aggravation.
Summary of the invention
To overcome the shortcomings of existing technologies, the purpose of the present invention is to provide a kind of willing, effect stability combustions
Feed channel self closing device to be gushed.
The present invention solves technical problem and adopts the following technical scheme that
Gas pipeline self closing device to be gushed, including the first gas pipeline, the second gas pipeline, in first combustion
What is sealed between feed channel and the second gas pipeline is socketed with one section of casing, and elastic slice is equipped at the first gas pipeline port, described
Elastic slice lower surface end is connected with tube wall below the first gas pipeline port, and the elastic slice upper surface is connected with valve for closing
The first gas pipeline is closed, the angle a at an acute angle between elastic slice lower surface extended line and upper surface.
Design feature of the invention also resides in:
When pipeline normal operation, the thrust for the combustion gas that the angle a bears the valve is less than the elastic force of the elastic slice, makes
Valve is kept it turned on；When pipeline is gushed, the thrust for the combustion gas that the angle a bears the valve is greater than the bullet of the elastic slice
Power, valve are closed at once.
The material of the valve is soft iron.
First gas pipeline is suspended below magnet.
Compared with the prior art, the beneficial effects of the present invention are embodied in:
1. the present invention is swift in response.When pipeline is to be gushed, when the combustion gas thrust that elastic slice of the invention is subject to is greater than elastic force, bullet
Piece is closed to the first gas pipeline direction, and elastic slice is bigger by the face of combustion gas thrust, bigger by thrust, to quickly complete pipe
The closure in road.
2. effect stability of the present invention.The present invention is automatically performed the closing to pipeline by physical principle when pipeline is gushed,
Effect stability is practical.
Detailed description of the invention
Fig. 1 usage state diagram one of the present invention
Fig. 2 usage state diagram two of the present invention
Fig. 3 elastic slice schematic diagram of the present invention
The appended drawing reference table of comparisons in figure: the first gas pipeline 1, the second gas pipeline 2, casing 3, elastic slice 4, valve 5, magnet
6。
Below by way of specific embodiment, and in conjunction with attached drawing, the invention will be further described.
Specific embodiment
As shown in Figure 1-3, gas pipeline self closing device to be gushed, including the first gas pipeline 1, the second gas pipeline
2, what is sealed between first gas pipeline and the second gas pipeline is socketed with one section of casing 3, the first gas pipeline port
Place is equipped with elastic slice 4, and elastic slice lower surface end is connected with tube wall below the first gas pipeline port, the elastic slice upper surface
Be connected with valve 5 for be closed the first gas pipeline, the angle a at an acute angle between elastic slice lower surface extended line and upper surface.It is described
First gas pipeline opening is oblique section, and the oblique section downwards, is closed convenient for valve.
The angle at the angle a is determined by the thrust of the combustion gas in gas pipeline: when pipeline normal operation, the angle a makes institute
The thrust for stating the combustion gas of valve receiving is less than the elastic force of the elastic slice, keeps it turned on valve；When pipeline is gushed, a
The thrust for the combustion gas that angle bears the valve is greater than the elastic force of the elastic slice, and valve is closed at once.
The material of the valve is soft iron.
First gas pipeline is suspended below magnet 6.The magnet is far from the valve.Pipeline is picked up to repair and be finished, really
It ensures safety, the magnet can be used, overcome elastic force, restart valve.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
