Specific implementation mode
In Fig. 1, Fig. 2, Fig. 3, film lower wall 23 is connected with disk on film 20 by screw, and diaphragm 22 is fixed on film lower wall 23 Between disk on film 20, pallet 21 is fixed on film among disk 20 and is in contact with diaphragm 22, and link block 15 is fixed on pallet 21 Above and with decompression adjusting bolt 11 it is connected, decompression spring 14 is fixed in decompression adjusting bolt 11,10 fitting of spring adjustment barrel In decompression adjusting bolt 11, superpressure adjusting bolt 12, superpressure spring 13 are fixed in spring adjustment barrel 10, reset transmission axle 18 It is fixed on lower housing 3, resetting spring 16, hand push button 17, which are fixed on, to be resetted in transmission axle 18, and 19 company of being fixed on of lever is interlocked It connects on block 15, interlocking lever bar 19 is in contact with locking plate b8, and locking plate b8 is fixed on fixed pivot pin b27, locking plate b8 and locking plate a9 phases Fastening, locking plate a9 are fixed on fixed pivot pin a25, locking plate a9 intermediate groove locking activity closing pieces arm 7, and movable closing piece arm 7 is fixed In on fixed pivot pin c28, fixed pivot pin a25, b27, c28 are fixed on lower housing 3, and torsional spring a24, b26 are separately mounted to fix On pivot pin a25, b27, movable closing piece arm 7 is fixed as one with movable closing piece 2, and movable closing piece 2 is fixed on main shaft 5, main shaft 5 On fixed main shaft seat 4,6 half of needle roller is in main shaft 5, and half is in fixed main shaft seat 4, fixed main shaft seat 4 and lower casing Body 3 is fastened by bolts part and is connected, and forms a kind of hyper-pressure pressure-loss disconnecting device.
Pipeline internal medium imports in 23 inner cavity of film lower wall, 22 induction medium pressure of rubber diaphragm generate certain thrust in On pallet 21, pallet 21 is promoted to move upwards, superpressure spring 13 generates certain spring force, bullet under the compression of superpressure adjusting bolt 12 A spring force part acts on lower housing 3, and a part is transmitted to by link block 15 on pallet 21, and pipe medium pressure is normal When, diaphragm 22 generates thrust and is less than spring force, and gearing lever 19 remains static or fine motion state.When pressure medium increase, When setting the upper limit more than pressure, the thrust that diaphragm 22 generates is more than 13 active force of superpressure spring, and pallet 21 moves upwards, stroke position When shifting is more than 1.5mm, gearing lever 19 is driven to be rotated clockwise around fixed pivot pin c28, interlocks 19 front end idler wheel edge lock of lever Piece b8 upper grooves move upwards, and start locking plate running part.When pressure medium is too low, is less than setting low pressure limit, diaphragm 22 The thrust of generation is less than 14 active force of decompression spring, at this point, 13 active force of superpressure spring all acts on lower housing 3, with company The separation of block 15 is connect, decompression spring 14 pushes pallet 21 to move downward by link block 15, when travel displacement is more than 1.5mm, drives It interlocks lever 19 to rotate counterclockwise around fixed pivot pin c28, interlocks 19 front end idler wheel of lever and moved downward along locking plate b8 upper grooves, Start locking plate running part.
When pipeline medium is normal, interlocks lever 19 and be in horizontality, locking plate b8 under the action of torsional spring b26 with locking plate a9 Fastening, while locking plate a9 intermediate groove locking activity closing pieces arm 7.Pipeline medium is abnormal, before pressure sensitive part interlocks lever 19 End idler wheel is moved downward along locking plate b8 upper grooves, starts locking plate running part, and locking plate b8 turns clockwise around fixed pivot pin b27 Dynamic, locking plate b8 and locking plate a9 threads off when rotating by a certain angle, and locking plate a9 surrounds the fixed pivot pin a25 inverse times under torsional spring a24 effects Needle rotates, and the lower ends locking plate a9 promotion activity closing piece arm 7 rotates clockwise.Pressure sensitive part abnormal signal passes through locking plate driving section Divide and is transmitted to movable closing piece arm 7.
The movement for cutting off valve base, makes to generate certain rotation torque on main shaft 5, needle roller or steel ball 6 are in movable closing piece 2 Under rotation forces, into the card slot of main shaft 5, needle roller half is in main shaft 5, and half is in fixed main shaft seat 4, fixed main shaft seat 4 be fixed, locks 5 rotary motion of main shaft.Pressure sensitive part abnormal signal is transmitted to work by locking plate running part Dynamic closing piece arm 7, locking plate running part dropout discrete state, movable closing piece arm 7 rotates clockwise, and drive activity closing piece 2 is suitable together Hour hands rotate, and movable closing piece arm 7 is fixed as one with movable closing piece 2.When movable closing piece 2 rotates by a certain angle, the torque of main shaft 5 Needle roller 6 is shifted onto in 2 serrated slot of movable closing piece, the locking release of main shaft 5, main shaft can be moved with 360 degree rotation.
For cutting mechanism under pressure normal condition, locking plate running part presses hand push button 17 in mutually buckle-like state is locked, multiple Position transmission axle 18 pushes locking plate b8 rotation, and locking plate running part is threaded off separation, so that the locking release of main shaft 5, main shaft can be with 360 degree rotation moves.Practical work instead of pressure sensitive part of hand push button unclamps hand push button 17, and resetting spring 16 can make Obtain 17 return of hand push button.
