The working procedure of the utility model magnetic control safety valve is as follows:
Refer to Fig. 4, before normal use, manual unlocking sealing mechanism 3A, mention button 211, carrying button 211 can drive button 214 up to carry, button 214 drives epithelium connecting rod 222 up to move with the epithelium 221 being fixedly connected with epithelium connecting rod 222, due to epithelium connecting rod 222 and upper magnet 232 inhale mutually and effect due to the pressure of epithelium 221 belows under, spool controlling rod 231 is followed the motion of magnet 232, make lower magnet 233 separated with armature 234, 2311 pairs of driving lever of groove in spool controlling rod 231 are bestowed the power making progress simultaneously, drive power arm 242 activity supporting point 241 that rotates up to move, drive resistance arm 243 activity supporting point 241 that rotates down to move simultaneously, the horizontal thrust that resistance arm 243 seals connecting rod 32 makes to seal connecting rod 32 and promotes sealing gaskets 31 toward suction port 1A translation, thereby intake duct A outlet is opened, now valve body 1 is opening state.Refer to Fig. 5, subsequently, carry button 211 and just under the effect of Returnning spring 213, set back, and button 214 keeps current location, intake duct A outlet A1 is opening state.
Refer to Fig. 6, in normal using process, the hypotony in valve body 1 or during without pressure, also, the hypotony of epithelium 221 belows or during without pressure, the pressure of epithelium 221 belows is less than the pressure of epithelium 221 tops, now, epithelium 221 is pressed down, drive epithelium connecting rod 222 to move down, and compress spool controlling rod 231, spool controlling rod 231 is moved down, lower magnet 233 is gradually near armature 234, 2311 pairs of driving lever of groove in spool controlling rod 231 apply a downward power simultaneously, drive power arm 242 activity supporting point 241 that rotates down to move, drive resistance arm 243 activity supporting point 241 that rotates up to move simultaneously, the horizontal pull that resistance arm 243 seals connecting rod 32 makes to seal connecting rod 32 and pulls sealing gasket 31 toward intake duct A outlet A1 translation, thereby laminating intake duct A outlet A1 also seals intake duct A outlet A1, thereby cut-out source of the gas.After recovering normally, can be according to before above-mentioned normal use, intake duct A outlet A1 is opened in the operating process of manual unlocking sealing mechanism 3A.
Refer to Fig. 7, in normal using process, during overpressure in valve body 1, while being also the overpressure of epithelium 221 belows, the pressure of epithelium 221 belows is greater than the pressure of epithelium 221 tops, now, epithelium 221 is up lifted gradually, drive epithelium connecting rod 222 up to move simultaneously, spool controlling rod 231 gradually with epithelium connecting rod 222 away from, due to the effect of spool controlling rod 231 and the position-limiting action of valve rod locating piece 235, magnet 232 can not up be moved with epithelium connecting rod 222, the attraction force between upper magnet 232 and epithelium connecting rod 222 more and more a little less than, refer to Fig. 8, after lifting on epithelium 221, attraction force between upper magnet 232 and epithelium connecting rod 222 is much smaller than the attraction force between lower magnet 233 and armature 234, now lower magnet 233 is inhaled mutually with armature 234, band movable valve plug controlling rod 231 moves down, 2311 pairs of driving lever of groove in spool controlling rod 231 apply a downward power, drive power arm 242 activity supporting point 241 that rotates down to move, drive resistance arm 243 activity supporting point 241 that rotates up to move simultaneously, the horizontal pull that resistance arm 243 seals connecting rod 32 makes to seal connecting rod 32 and pulls sealing gasket 31 toward intake duct A outlet A1 translation, thereby laminating intake duct A outlet A1 also seals intake duct A outlet A1, thereby cut-out source of the gas.After recovering normally, can be according to before above-mentioned normal use, intake duct A outlet A1 is opened in the operating process of manual unlocking sealing mechanism 3A.
Refer to Fig. 9, in normal using process, during the excessive or air outlet 1B standard-sized sheet of fluid flow in valve body 1, also, cross the fluid flow that fluid flow in runner 411, air vent B and air outlet channel C is greater than the intake duct A of suction port 1A place; Now, flow control member 44 moves toward crossing runner 411 imports under the effect of pressure difference, and compress flow control spring 43, also be, sleeve 441 in flow control member 44 slides towards crossing runner 411 imports along balancing pole 42, and compresses flow control spring 43, until spoiler 442 was fitted in the peripheral wall of runner 411 imports, the import of sealing flow channels, cuts off fluid moment of flowing relatively.Now, because the pressure of epithelium 221 belows is less than the pressure of epithelium 221 tops, now, epithelium 221 is pressed down, drive epithelium connecting rod 222 to move down, and compress spool controlling rod 231, spool controlling rod 231 is moved down, lower magnet 233 is gradually near armature 234, 2311 pairs of driving lever of groove in spool controlling rod 231 apply a downward power simultaneously, drive power arm 242 activity supporting point 241 that rotates down to move, drive resistance arm 243 activity supporting point 241 that rotates up to move simultaneously, the horizontal pull that resistance arm 243 seals connecting rod 32 makes to seal connecting rod 32 and pulls sealing gasket 31 toward intake duct A outlet A1 translation, thereby laminating intake duct A outlet A1 also seals intake duct A outlet A1, thereby cut-out source of the gas.Refer to Figure 10, because flow control member 44 and choked flow boss 41 are that the relative fluid that cuts off flows, after the pressure balance in each passage between suction port 1A and air outlet 1B, flow control member 44 is just subject to the restoring force effect of flow control spring 43 and auto-returned initial position is got back on the position shown in figure.After recovering normally, can be according to before above-mentioned normal use, intake duct A outlet A1 is opened in the operating process of manual unlocking sealing mechanism 3A.
Therefore, by technique scheme, realize the utility model magnetic control safety valve automatically closing when superpressure state and super flow, improved the stability of gas supply and the Security of use.
With respect to prior art, the utility model magnetic control safety valve has improved the stability of gas supply and the Security of use.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or distortion are not departed to spirit and scope of the present utility model, within if these changes and distortion belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and distortion.
