Described linked component comprises horizontally disposed continuous motion stem 34, the one end that is positioned at suction port 1 on described continuous motion stem 34 is arranged with flow spoiler 2, microsprings 3 and successively for opening and closing the air inlet sealing gasket 35 of the valve port 4 on valve body, described flow spoiler 2 matches with the constrictor 36 of being located at suction port 1 inside, the intermediate portion of described continuous motion stem 34 is connected with lever 29, the other end of described continuous motion stem 34 is provided with spring fitting platform 32, on described spring fitting platform 32, be positioned with and open and close spring 33, the other end of described keying spring 33 is connected with the inwall of valve body 37; The longitudinal rib that guiding and centralizing function have been set on continuous motion stem 34, can better guarantee that it moves along medial axis.
Described fire prevention control valve comprises hollow valve body, on the cylindrical of described hollow valve body, be positioned with successively from left to right annular iron plate 18, ring magnet 19 and ring armature 20, spring banking stop 27 has been located in the inside of described hollow valve body, on described spring banking stop 27, be fixed with locking spring 26, the other end of described locking spring 26 is connected with magnet carrier 25, and described magnet carrier 25 inside are provided with movable magnet 24, magnet carrier 25 front ends of ring magnet 19 supporting settings and are provided with the sealing gasket 23 of giving vent to anger; Spacing between described annular iron plate 18 and ring armature 20 is greater than the thickness of ring magnet 19.
Described lever 29 is special-shaped rod member, and the bottom of lever 29 is hinged with the bearing pin 31 being fixed on valve body 37, and the two ends of lever 29 are and are flexibly connected with center controlling rod 17, continuous motion stem 34.Be specially: can on continuous motion stem, offer the rectangle groove that Ke Rong center controlling rod passes through, then center controlling rod 17 forms hook even through this continuous motion stem 34.On Ye Ke center controlling rod 17 and continuous motion stem 34, offer through hole, two of lever 29 connects with this through hole movable hook respectively.As long as meet usage requirement.
The lower end of described interior fastener 14 is provided with annular lifter board, and described button 11 can upper and lower slip in the center hole of interior fastener 14.Described connecting rod 9 is inverted T shape structure, and its lower end is provided with mountion plate, and described pressure regulation sheet 7, epithelium 5 are positioned above mountion plate by fastening piece 8.Described microsprings 3 one end contact with flow spoiler 2, the other end contacts with air inlet sealing gasket 35.
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 29 compositions and the linked component being formed by flow spoiler 2, microsprings 3, keying spring 33, continuous motion stem 34, air inlet sealing gasket 35 being connected with button 11, and then air inlet sealing gasket 35 is opened from valve port 4, now pipeline fluid starts to flow to air outlet 22 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 33 simultaneously, and lever 34 fixes on this position under the effect of location piece 16.Referring to accompanying drawing 2, mentioning after button 10 decontrols, carry automatic pick between armature 13 in button 10 and magnetic part 12, make to propose button 10 resets.And permanent magnet 15, center controlling rod 17 in hot environment, loses adhesive each other or owing to being subject to after external force fragmentation, keying spring 33 still laterally drives rapidly air inlet sealing gasket 35 close port 4 in linked component under the effect of elastic force.
When fire prevention control valve is manually opened, promote ring magnet 19 and drive Sealing and 18 adhesives of ring-like iron plate that formed by the sealing gasket 23 of giving vent to anger, movable magnet 24 and magnet carrier 25, now due to the effect movable magnet 24 of magnetic, be suspended in the centre of ring magnet 19, compress by force locking spring 26 and open valve.
During valve closing, promote ring magnet 19 and ring-like armature 20 adhesives, black box, due to together the fit sealing platform 21 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 34 is applied is less than the power to the right that 33 pairs of continuous motion stems 34 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 35 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 15, the auxiliary lower brute force of restriction at location piece 16 makes connecting rod 9 and permanent magnet 15 separate, now continuous motion stem 34 will laterally drive rapidly air inlet sealing gasket 35 close port 4 on linked component under the elastic force effect that opens and closes spring 33, 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 22 exceeds the flow of normal use, because the pressure difference between suction port 1 and air outlet 22 is excessive, the pressure of suction port 1 and flow are greater than pressure and the flow of air outlet 22, under the effect of large flow and pressure, promote flow spoiler 2 compression mini springs 3 and constrictor 36 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 35 close port 4 in linked component under the effect that opens and closes spring 33.
The utility model is provided with double insurance, and the air inlet sealing gasket 35 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 19 in fire prevention control valve was lost efficacy by high-temperature magnetic, at the effect of the locking spring 26 elastic force sealing gasket 23 that promotes all the time to give vent to anger, be kept closed with the sealing platform 21 of outlet side, cut off the generation of the effective Accident prevention of source of the gas.
