Following steps:
Step 1: the first tube body of fire extinguishing sprayer is connect with steam line, since the elastic force of the first spring has anti-baffle plate to decline
Effect, the air pressure in the first tube body needs to overcome the first spring force, could push down on baffle, increases the interior of the first tube body
Portion's air pressure, until baffle is moved to below hole for water spraying, the gas of the first tube body can be sprayed from hole for water spraying, although hole for water spraying goes out
Mouth has some protections or dust guard, those protections and dust guard can be opened if air pressure is sufficiently large；
Step 2: the second tube body of fire extinguishing sprayer is connect with water supply line, since the elastic force of second spring prevents bullet block from declining
Effect, the second intracorporal hydraulic pressure of pipe needs to overcome second spring elastic force, could be pressed downward bullet block, increase the interior of the second tube body
Portion's hydraulic pressure, until bullet block is moved to below hole for water spraying, the liquid of the second tube body can be sprayed from hole for water spraying, due to hydraulic pressure at this time
Be it is bigger, can open water spray hole exits some protections or dust guard；
Step 3: the air pressure of the first tubular body of adjustment, the stress relationship of baffle change, when air pressure is less than below baffle
When spring force, baffle can be pushed up by spring force, and due to being inclined design at the top of baffle, from the side, baffle is in three
Angular shape, for baffle during moving up, baffle is gradually all to block hole for water spraying, the amount for the gas that hole for water spraying sprays
And be gradually reduced, according to the needs at scene, when if necessary to spray bulk gas, gas supply air pressure is just increased, if needed
The amount for reducing jet is reduced by gas supply air pressure, springs back baffle, blocks hole for water spraying, if stopping gas supply, baffle is sprung back to just
Begin height, is now placed in the top of hole for water spraying；
Step 4: the second tubular body of adjustment is hydraulic, the stress relationship of bullet block changes, and is less than below bullet block when hydraulic
When spring force, bullet block can be pushed up by spring force, and due to being inclined design at the top of bullet block, from the side, bullet block is in three
Angular shape, for bullet block during moving up, bullet block is gradually all to block hole for water spraying, the amount for the liquid that hole for water spraying sprays
And be gradually reduced, according to the needs at scene, water supply pressure is just increased when needing to spray a large amount of water, if necessary to reduce spray
The amount of water, is reduced by water supply pressure, springs back bullet block, blocks hole for water spraying, if stopping supplying water, bullet block springs back to elemental height,
It is now placed in the top of hole for water spraying；
Step 5: fire extinguishing sprayer after first use, unscrews the dome of spray head, check inside head body there is free from admixture, into
Row cleaning, after having cleared up, screws dome, fire extinguishing sprayer can continue to use；
Step 6: if the protective device on the outside of hole for water spraying is protected using made of the solvable paper in claim 2 scheme
Circle, since the guard circle is the attribute of solvable paper, after fire extinguishing sprayer is once sprayed water, guard circle is just ineffective, needs to spray
If water hole is protected, then needing to be arranged a completely new guard circle on the outside of hole for water spraying；
Step 7: if the protective device on the outside of hole for water spraying looks for block using the structure in claim 3 scheme again
Then harmless cloth is banded in head body by completely new non-woven fabrics with rubber band, protect hole for water spraying；
Step 8: if the protective device on the outside of hole for water spraying using the structure in claim 4 scheme, as long as quilt
The baffle pressed down resets to script vertical state, so that it may reuse.
