Magnet 45 deflects relative to the first armature 442, so that g1=g4 > g2=g3；It is same to pass through adjusting left and right two panels bistable state
Torque-motor adjusts gasket 9, so that G1=G4 > G2=G3.First magnet steel 42 (two) of monostable torque-motor 4 is carried out
Lower direction is magnetized, and is N grades close to magnetizer 41 on first, is S grades close to the first lower magnetizer 45；For bistable state torque
The magnet steel (number does not provide) of motor 10, magnetizing direction is also such.After the completion of magnetizing, as shown in figure 5, monostable torque horse
Permanent magnet flux Ф p1 up to 4 can generate permanent magnetic torque Tp1, the change so that the first bourdon tube 443 bends on the first armature 442
Shape finally makes first baffle 445 force together with monostable torque-motor valve base 6, generates sealing force；For bistable state torque
For motor 10, permanent magnet flux Ф p2 can generate permanent magnetic torque Tp2 on armature (number does not provide), so that bourdon tube (is compiled
Number do not provide) it occurs bending and deformation, so that baffle (number does not provide) is forced together with bistable state torque motor valve valve seat 8,
Generate sealing force；Fig. 5 is the closed position state of the highly reliable advantageous torque motor valve of the invention.
Highly reliable advantageous torque motor valve working principle of the invention is as follows: as shown in figure 5, monostable torque-motor 4
Two first coils 43 in left and right are all made of inside and outside double-layer coil design (i.e. totally four coils, 1~coil of coil 4), by four lines
Circle is connected using parallel way, and four redundancy designs have been achieved.When needing monostable torque-motor valve to open, its coil is given
Galvanization, current direction in monostable torque-motor 4 as shown in figure 5, can thus generate electromagnetism magnetic flux Ф e1, Ф e1 and Ф
P1 is overlapped mutually at g1 and g4, and mutually (g1 and g3 are respectively magnetizer 41 and the first armature on first to abatement at g2 and g3
442 in the gap of the left and right sides, and g2 and g4 are respectively the gap of the first lower magnetizer 45 and the first armature 442 in the left and right sides),
Clockwise unlatching moment To1 is finally generated on the first armature 442, opens monostable torque-motor valve.When needing to close
When, as shown in fig. 6, removing the electric current in first coil 43, the bending deformation of the first bourdon tube 443 can be produced in the first armature 442
Raw close moment Tc1 counterclockwise, closes monostable torque-motor valve.
As shown in figure 5, the coil of the left and right of bistable state torque-motor 10 two (number does not provide) is all made of the inside and outside double-deck line
Circle design, outer layer are the circle that bursts at the seams, and internal layer is to close coil, totally four coils.Its connection type is in parallel with the circle 2 that bursts at the seams for the circle 1 that bursts at the seams,
It closes coil 1 and closes 2 parallel connection of coil, switch coil so realizes double redundancy design.When needing bistable state torque motor valve to beat
When opening, burst at the seams circle 1 and 2 galvanizations of circle that burst at the seams to it, and current direction is as shown in figure 5, thus can be in bistable state torque-motor 10
Middle generation electromagnetism magnetic flux Ф e2, Ф e2 and Ф p2 is overlapped mutually at G1 and G4, and mutually (G1 and G3 distinguish abatement at G2 and G3
Be magnetizer 101 on second and the second armature 1042 in the gap of the left and right sides, G2 and G4 be respectively the second lower magnetizer 105 with
Gap of second armature 1042 in the left and right sides), finally unlatching moment counterclockwise is generated on armature (number does not provide)
To2 opens bistable state torque motor valve.When needing to close, coil 1 is closed to it and closes 2 galvanization of coil, current direction is such as
Shown in Fig. 6, electromagnetism magnetic flux Ф e2, the Ф e2 and Ф p2 that pass coil generates so mutually cuts down at G1 and G4, at G2 and G3
It is overlapped mutually, finally generates clockwise close moment Tc2 on armature (number does not provide), close bistable state torque motor valve
It closes.
As shown in fig. 6, when monostable torque-motor valve and bistable state torque motor valve are opened, fluid flow direction
Direction is indicated for arrow, is successively passed through: inlet attack 14,15 left side stepped hole of valve body, bistable state torque motor valve valve seat 8,
Plug 7,15 right side center of valve body two cylinder stepped holes on the upper side, monostable torque-motor valve base 6.
Unspecified part of the present invention belongs to technology well known to those skilled in the art.
