Description
Technical field
Fire resisting damper technical field is the utility model is related to, specially a kind of oxygenerator automatic fireproof valve.
Background technology
The oxygen concentration of oxygenerator output is higher than 90%, because oxygen has strong oxidation characteristic, once because oxygen therapic patient
The oxygen hose for exporting oxygen is ignited accidentally, due to there is continual high-concentration oxygen to flow out in oxygen output tube, because
This flame will progressively burn with the gas outlet tube of oxygen to fuselage, and fire occurs for the oxygenerator that finally ignites.And fire resisting damper then can
Burning is prevented, and flame is extinguished before fire resisting damper.And or present fire resisting damper is not suitable for the oxygen output tube of oxygenerator
On road, otherwise flame combustion can not be controlled completely.Such as Patent No. 205896321U, the day for announcing is on January 18th, 2017, title
For a kind of oxygenerator fire resisting damper, it is to be blocked the oxygen of output by self-closing flexible member, reaches the purpose of fire extinguishing, still
The output pressure of most oxygenerators is more than 100Kpa, and flow is more than 5L/ minutes, the Packing spring in fire resisting damper can be caused to have
Effect closure, oxygen leakage is still had, and described fire proofing material can lose flame retardant effect in high-concentration oxygen, lead to not reach
To the effect of flame-retarding fire-extinguishing.
The content of the invention
The purpose of this utility model is to provide a kind of oxygenerator automatic fireproof valve, solves prior art oxygenerator fire resisting damper
The problem of flame-retarding fire-extinguishing can not effectively be realized.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
A kind of oxygenerator automatic fireproof valve of the utility model, including valve body, the valve body inner hollow, the valve body
One end is connected with suction nozzle, and the other end is connected with outlet nozzle, and one end sidepiece that the valve body is connected with suction nozzle connects provided with by-pass flow
Mouthful, valve slide block assembly is provided with inside the valve body, stepped hole is provided with inside the valve body, is provided with the stepped hole and is used to keep off
The only step surface of valve slide block assembly.The utility model fire resisting damper general structure is simple, easy to install.
Further, the valve slide block assembly includes valve sliding block, and one end that the valve sliding block is located at inlet end leads to
Cross flexible member to be connected with front supporting member, be connected positioned at one end of outlet side by drag-line with rear support, the rear support
It is made of inflammable material.Rear support is easily broken in the case of heat so as to release valve sliding block, and valve sliding block is in bullet
Property element pulling force effect under reset so as to realize block oxygen function.
Yet further, the valve sliding block is placed in the macropore on stepped hole, its outer shape with it is big on stepped hole
Hole is engaged.Fire resisting damper ensures that oxygen can be from the gap stream between the macropore on valve sliding block and stepped hole in normal state
Cross.
Yet further, the outer profile size of the front supporting member is more than the hole diameter on stepped hole, the rear support
The outer profile size of part is more than the macropore internal diameter on stepped hole.Ensure that front supporting member and rear support can stablize fixed valve cunning
Block.
Yet further, the by-pass flow interface is arranged on the inlet end cavity of valve body.The housing of the outlet nozzle is hollow
Housing, the hollow housing are made of combustible material.Will when running into high temperature using hollow housing made of thermo-sensitive material
Rupture at once, discharge the filling fire extinguishing material in hollow housing.
Yet further, fire extinguishing material is provided with the hollow housing, the fire extinguishing material is ultra-fine dry powder extinguishing agent.When
After hollow housing preheating outer wall breakage, the fire extinguishing material in hollow housing actively discharges knock down the flame.
Yet further, the by-pass flow interface outer end is connected with relief valve.Relief valve monitors the pressure of automatic fireproof valve in real time
Power changes, and when running into naked light, rear support is easily broken in the case of heat so as to which release valve sliding block, valve sliding block exist
Resetted under the pulling force effect of flexible member causes valve body internal pressure to raise while blocking oxygen output, when pressure reaches critical point
When, then valve is opened, and gas flows directly out.
Compared with prior art, advantageous effects of the present utility model：
Firstth, combustion-supporting gas is blocked, avoids fire spreading.The utility model oxygenerator runs into naked light with automatic fireproof valve
When, the front supporting member in valve slide block assembly is heated broken, and valve sliding block resets under the pulling force of flexible member and is against step
On the step surface in hole, gas is blocked by valve body cavity, air pressure increase in cavity, therefore the oxygen that suction nozzle enters is then from by-pass flow
Interface flows out, and thoroughly prevents the oxygen supply of outlet nozzle, realizes the supply for blocking combustion-supporting gas.
Secondth, using Chemical Inhibition Method, naked light is extinguished.The utility model oxygenerator is hollow with automatic fireproof valve outlet nozzle
It is molten broken that housing runs into the naked light outer wall that is heated, and the extinguishing chemical release of filling in hollow housing, destroys the chain reaction of burning, makes burning
Terminate, so as to reach fireproof purpose.
3rd, easy to use, the outlet nozzle of the utility model oxygenerator automatic fireproof valve and the silica gel of nasal oxygen tube practice level,
Suction nozzle is connected with oxygenerator oxygen outlet, can be used on oxygenerator, easy installation and removal.
