The working procedure of control valve when burning is used:
(1) gas combustion range ignition, flame-out process.
Pushing block 20 by shifting bottom position onto, location pushing block 18 pushes in valve rod 11, seal ring 10 on the valve rod 11 leaves the sealing surface b of main valve body 12, the end face of valve rod 11 pushes away the seal ring on the magnetic control safety valve 15 the sealing surface a of emergency valve seat 3 simultaneously, this moment, gas circuit was opened, combustion gas enters in the valve from suction port, enters the anterior chamber f of the film 41 in the front valve shell 53 through sealing surface a, groove c, sealing surface b, passage d and hole e.The bearing pin 19 of locating simultaneously on the pushing block 18 is depressed drive link 17, drive link 17 rotates around bearing pin 16, drive link 17 drives flap 27 again and rotates around bearing pin 28, small valve-rod 34 is depressed, according to the bernoulli principle, combustion gas is after throttle orifice g sprays at a high speed, pressure in the t of chamber reduces, so the pressure in the film 41 rear chamber h is greater than under the pressure effect in the t of chamber, elastic force and firepower adjustable lever 44 that film 41 overcomes spring 38 move together backward, and the combustion gas in the h chamber enters main fire-fighting mouth 52 through outlet pipe 37 and is discharged from.O-ring seals 43 also breaks away from the sealing surface of front valve shell 52, and combustion gas enters main fire-fighting mouth 52, and also some combustion gas enters central nozzle 54 simultaneously.Ignitor switch 59 connections this moment, the spray point discharge.Combustion gas is lighted, and the thermocouple of magnetic control safety valve 1 is heated, and about 10-20 is after second, and safety valve holds seal ring 5, can decontrol pushing block 20.After pressing pushing block 20, the A end of U-shaped pull bar 57, accompanying drawing 5 (is seen) in position from the pushing block 18 of location 1., through 2. arriving 3., after loosening pushing block 20, the A of U-shaped pull bar 57 end again from the position 3. through 4. arriving 5., location pushing block 18 is held by U-shaped pull bar 57,18 of the pushing blocks in location are return a bit of distance, this moment, valve rod 11 was pushed up back a bit of distance under the effect of spring 8, but seal ring 10 still breaks away from sealing surface b, because of seal ring 5 is held, the end face of valve rod 11 leaves the end face of seal ring 5, seal ring 5 can not push back sealing surface a yet, so combustion gas can continue to enter in the valve, this moment, bearing pin 19 also left drive link 17, small valve-rod 34 is return under spring 31 effects and has been closed the exhaust passage, and firepower adjustable lever 44 is no longer mobile.
In the time will stopping working, to press pushing block 20 simultaneously and loosen again, 1. 6., 7. the position of the A of U-shaped pull bar 57 end from the pushing block 18 of location 5. through getting back to the original place, location pushing block 18 leaves, valve rod 11 is under the effect of spring 8, and seal ring 10 is pushed back sealing surface b, and blast tube is closed.As accident extinguishing, the thermocouple cooling, magnetic control valve 1 dead electricity, seal ring 5 is pushed back sealing surface a under the effect of spring 4, thereby closes gas-entered passageway, plays the safety protection effect.
(2) big or small flame is regulated
Little thermal transfer joint: depress pushing block 26, small valve-rod 56 is depressed, combustion gas enters from aperture m, enter the rear chamber h of film 41 through O-ring seals 21 sealing part and aperture n, this moment, ante-chamber f of portion and rear chamber h pressure must equate, under the effect of spring 38, firepower adjustable lever 44 is pushed back, and closes the passage that enters main fire-fighting mouth 52 gradually, and firepower also just reduces gradually, after reaching the big or small firepower of needs, can loosen pushing block 26, small valve-rod 56 is return closing passage, and combustion gas stops to enter the h chamber, firepower adjustable lever 44 also just stops to move, thereby reaches little thermal transfer program.Regulate speed, as long as control enters the speed of h chamber combustion gas, regulating valve stem 47 precessions, the combustion gas speed that just can slow down and enter the h chamber.
Big fire is regulated: depress pushing block 29, small valve-rod 34 is depressed.According to the bernoulli principle, combustion gas is through throttle orifice g, after the ejection, the pressure in the t of chamber reduces at a high speed, so the pressure in film 41 rear chamber is greater than the pressure in the t of chamber, under the pressure effect of the interior combustion gas of chamber f forwardly, film 41 overcomes the elastic force of spring 38 and firepower adjustable lever 44 moves together backward, and the combustion gas in the rear chamber h enters main fire-fighting mouth 52 through outlet pipe 37 and is discharged from, and is opened gradually to blast tube, firepower increases again gradually, thereby reaches the purpose of regulating firepower.
