Abstract
The utility model provides a high-low pressure double-blocking type air flow safe valve, which adopts the following technical scheme that the outlet of an air inlet passage is provided with a flow stopping piece, the flow stopping piece is connected with one end of a spring through the spring connecting point on the flow stopping piece, the other end of the spring is fixed on the air inlet passage, the size of the flow stopping piece is suitable for blocking the air inlet passage and an air outlet passage, and the flow stopping piece can block the air inlet passage when the spring is in a normal state, and can block the air outlet passage after the spring is extended and deformed. When the air flow safe valve is in use, if air flow is too large, the spring has large deformation, and the flow stopping piece extends to directly block the air outlet passage; when the air flow pressure is too small, the spring resets to be in place to block the air inlet passage, and the air stopping can be realized; if the air flow is stably output, the spring is positioned at the middle part, the stable air output can be realized, and the stable air use can be ensured; and in addition, as one-way air transmission is adopted in the air flow safe valve, the dangerous gas leakage can be prevented, so that the high-low double-blocking type air flow safe valve is safe and effective, and can prevent the condition such as explosion and the like destroying the life and the property of people.
Description
Technical field:
The utility model relates to a kind of safety valve, relates in particular to a kind of pressure control flow, reveals the two resistance formula air-flow safety valves of high low pressure of blast easily easily.
Background technique:
Traditional air flow valve is indicated by pressure gauge, pressure indication such as air compressor, such as He-Ne gas cylinder and oxygen cylinder, the tolerance of nitrogen bottle etc. shows by pressure gauge, but, pressure gauge is broken in the process of the inflation of being everlasting, and uncontrollable its leakage, its working gas remains on certain air flow stream output, and this device that is difficult for taking place to reveal is not realized, and be difficult to realize automation,, directly jeopardize the people's the security of the lives and property because blast and loss that the leakage of gases such as coal gas and rock gas causes are huge.
The model utility content:
The purpose of model utility:
For provide a kind of can the control gaseous flow, prevent the excessive leakage of flow, the two resistance formula air-flow safety valves of high low pressure that need not manometric indication can under high gas flow discharge and low-flow discharge, close automatically.
In order to reach as above purpose, the utility model is taked following technological scheme: the intake duct outlet has the fluid stopping part, the fluid stopping part is connected with spring one end by the spring tie point that has on it, the other end of spring is fixed on the intake duct, described fluid stopping part size can be blocked intake duct and air outlet channel, described fluid stopping part can be blocked the fluid stopping part of air outlet channel for can block intake duct when the spring normality after elongation deformation; Described air outlet channel has the air-flow transfer chamber near spring one side.The further technological scheme of the utility model is: an end of the disconnected link of described spring is fixed on the intake duct bottom by spring card slot.
The further technological scheme of the utility model is: described intake duct links to each other with air-inlet cavity, and described air outlet channel links to each other with outlet chamber.
The further technological scheme of the utility model is: the air input joint interface is arranged on the described air-inlet cavity, the air outlet adapter interface is arranged on the described outlet chamber, the outside that described air-inlet cavity stretches into the part of air-flow transfer chamber links to each other with the air-flow transfer chamber by outside thread, and there is leakage stopping pad at the position that described air-flow transfer chamber contacts with air-inlet cavity.
Adopt the as above model utility of technological scheme, have following beneficial effect: in the time of use, if air-flow is excessive; spring generation large deformation then; stretch out the fluid stopping part, air outlet channel is directly blocked, prevent that overflowing of air flow from causing dangerous hidden danger; when stream pressure too small; then spring recovers at one's own department or unit intake duct to be blocked, thereby realizes dying; therefore the reminds people ventilation can all realize protection in high-pressure and low-pressure.
If air-flow output steadily, spring is in the middle part so, neither block air outlet channel, do not block intake duct yet, realize air-flow output stably, ensure the steady of usefulness gas, and because the unidirectional gas transmission of the utility model, can prevent the hazardous gas leakage, so safe and effective, having prevented that blast from waiting the thing of harm people's life and property to take place.
Description of drawings:
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of model utility:
Wherein: 1. leakage stopping pad; 2. spring; 3. spring card slot; 4. fluid stopping part; 5. air-flow transfer chamber; 6. air outlet channel; 7. air-inlet cavity; 8. intake duct; 9. spring tie point; 10. cover for seat; 11. air input joint interface; 12. outlet chamber; 13. air outlet adapter interface.
Embodiment:
Below in conjunction with accompanying drawing an embodiment of the present utility model is described, present embodiment does not constitute restriction of the present utility model:
In order to reach as above purpose, the utility model is taked following technological scheme: intake duct 8 outlets have fluid stopping part 4, fluid stopping part 4 is connected with spring 2 one ends by the spring tie point 9 that has on it, spring 2 other ends are fixed on the intake duct 8, described fluid stopping part 4 sizes can be blocked intake duct 8 and air outlet channel 6, described fluid stopping part 4 can be blocked the fluid stopping part 4 of air outlet channel 6 for can block intake duct 8 when the spring normality after elongation deformation; Described air outlet channel 6 has air-flow transfer chamber 5 near spring 2 one sides.
The further technological scheme of the utility model is: an end of described spring 2 disconnected links 4 is fixed on intake duct 8 bottoms by spring card slot 3.
The further technological scheme of the utility model is: described intake duct 8 links to each other with air-inlet cavity 7, and described air outlet channel 6 links to each other with outlet chamber 12.
The further technological scheme of the utility model is: on the described air-inlet cavity 7 air input joint interface 11 is arranged, on the described outlet chamber 12 air outlet adapter interface 13 is arranged, the outside that described air-inlet cavity 7 stretches into the part of air-flow transfer chamber 5 links to each other with air-flow transfer chamber 5 by outside thread, and described air-flow transfer chamber 5 has leakage stopping pad 1 with the position that air-inlet cavity 7 is removed.
Among Fig. 1: leakage stopping pad 1 prevents that air-flow from leaking, and air input joint interface 11 is used for connecting air input joint, and air outlet adapter interface 13 is used for connecting air outlet adapter.
Adopt the as above model utility of technological scheme, have following beneficial effect, in the time of use; if air-flow is excessive, then deformation takes place in spring 2, stretches out fluid stopping part 4; air outlet channel 6 is directly blocked; prevent that overflowing of air flow from causing dangerous hidden danger, too small when stream pressure, then spring 2 recovers at one's own department or unit; intake duct 8 is blocked; thereby realize dying, therefore the reminds people ventilation can all realize protection in high-pressure and low-pressure.
If air-flow is exported steadily, spring 2 is in the middle part so, neither blocks air outlet channel 6, does not also block intake duct 8, realizes air-flow output stably, ensures the steady of usefulness gas.
And because the unidirectional gas transmission of the utility model can prevent the hazardous gas leakage, so safe and effective, having prevented that blast from waiting the thing of harm people's life and property to take place.
