During the utility model work, referring to accompanying drawing 1, mention button 10 and drive successively connecting rod 9, fastening piece 8, pressure regulation sheet 7, epithelium 5, permanent magnet 15, center controlling rod 17, the control unit of regulations and parameters 20 compositions and the linked component being formed by flow spoiler 2, microsprings 3, keying spring 37, continuous motion stem 35, air inlet sealing gasket 38 being connected with button 12, and then air inlet sealing gasket 38 is opened from valve port 4, now pipeline fluid starts to flow to air outlet 25 through the valve pocket of valve body.Fluid is owing to there being certain flowing pressure in the middle of the process of circulation, and epithelium 5 sticks out under the effect being under pressure, and is compressing keying spring 37 simultaneously, and lever 20 fixes on this position under the effect of location piece 18.Referring to accompanying drawing 2, mentioning after button 10 decontrols, carry automatic pick between armature 14 in button 10 and magnetic part 13, make to propose button 10 resets.And permanent magnet 16, center controlling rod 17 in hot environment, loses adhesive each other or owing to being subject to after external force fragmentation, keying spring 37 still laterally drives rapidly air inlet sealing gasket 38 close port 4 in linked component under the effect of elastic force.
When fire prevention control valve is manually opened, promote ring magnet 22 and drive Sealing and 21 adhesives of ring-like iron plate that formed by the sealing gasket 26 of giving vent to anger, movable magnet 27 and magnet carrier 28, now due to the effect movable magnet 27 of magnetic, be suspended in the centre of ring magnet 22, compress by force locking spring 29 and open valve.
During valve closing, promote ring magnet 22 and ring-like armature 23 adhesives, black box, due to together the fit sealing platform 24 of outlet side of two Action of Gravity Fields of magnetic force and spring force, cuts off source of the gas and exports.
Referring to attached Figure 4 and 5, when there is under-voltage supply in pipeline fluid, the pressure being subject to due to epithelium 5 is less, now its power left that continuous motion stem 35 is applied is less than the power to the right that 37 pairs of continuous motion stems 35 of spring apply that opens and closes, balance is originally broken, under the effect of elastic force, linked component moves right rapidly, makes air inlet sealing gasket 38 close port 4, cuts off fluid source.
Referring to accompanying drawing 6, when there is super large pressure in the supply pressure of pipeline fluid, when the pressure being subject to due to epithelium 5 is greater than the suction between connecting rod 9 and permanent magnet 16, the auxiliary lower brute force of restriction at location piece 18 makes connecting rod 9 and permanent magnet 16 separate, now continuous motion stem 35 will laterally drive rapidly air inlet sealing gasket 38 close port 4 on linked component under the elastic force effect that opens and closes spring 37, thereby cuts off the fluid source of super large pressure feed.Guarantee the use safety of normal fluid, the process of especially using at inflammable gas has effectively played the safety that combustion gas is used.
Referring to accompanying drawing 4, state at normal fluid flow, flow spoiler 2 under the elastic force of microsprings 3 and the acting in conjunction of hydrodynamic pressure in state of equilibrium, now keep an effective distance between the two, when air outlet 25 exceeds the flow of normal use, because the pressure difference between suction port 1 and air outlet 25 is excessive, the pressure of suction port 1 and flow are greater than pressure and the flow of air outlet 25, under the effect of large flow and pressure, promote flow spoiler 2 compression mini springs 3 and constrictor 39 laminatings, relatively play the effect of choked flow decompression.After laminating, the balance of linked component is broken, and laterally drives rapidly air inlet sealing gasket 38 close port 4 in linked component under the effect that opens and closes spring 37.
The utility model is provided with double insurance, and the air inlet sealing gasket 38 in linked component can play closing function; When valve environment in the middle of using process is spent height or breaking out of fire, ring magnet 22 in fire prevention control valve was lost efficacy by high-temperature magnetic, at the effect of the locking spring 29 elastic force sealing gasket 26 that promotes all the time to give vent to anger, be kept closed with the sealing platform 24 of outlet side, cut off the generation of the effective Accident prevention of source of the gas.
