Working principle of the utility model or working procedure are:
When valve will be opened, give motor stator 23 and lower coil 28 energisings, along with lower coil 28 energisings, it produces magnetic field and lower magnetic steel 29 magnetic fields offset, and suction disappears between following moving iron core 12 and the following static iron core 11; Motor stator 23 energising backs produce magnetic field, make motor move son 13 and produce induction current, and induction current produces the magnetic force that moves up under the action of a magnetic field; Moving under the magnetic force, moving assembly drives valve rod 8 and is pulled upwardly.Valve rod 8 lower ends have secondary valve seal; Secondary valve seal is owing to be pressed on the secondary valve base under the secondary 3 upper and lower medium pressure difference effects of secondary valve seal; When the mobile magnetic force on acting on valve rod 8 surpassed the secondary 3 Sealing extruding forces of secondary valve seal, the secondary valve seal of valve rod band was pulled upwardly secondary opening of valves.Behind the secondary opening of valves, the medium in the lumen in part 31, lumen top 30 and the air gap 15 flows to the cavity of resorption 1 of valve body 9 through secondary valve base, pod apertures 2, and the outlet plenum 5 through valve body 9 flows out valve bodies 9 then.Along with medium flows out, also some medium gap between damping hole 32, valve cup 7 and valve gap 10 flows to part 31 in the lumen simultaneously, but the passage that medium flows out is big; The passage that flows to is little; So behind certain hour, the pressure medium in the lumen in part 31, lumen top 30 and the air gap 15 is lower than the pressure medium in the lumen exterior portions 6, moving on the valve cup 7 under the mobile magnetic force acting in conjunction of this pressure difference and valve rod 8; Air gap 15 disappears; Go up moving iron core 14 and last static iron core 16 adhesives, the valve main valve is opened, and the valve opening process finishes.Behind the valve opening; Motor stator 22 outages under the control system effect, lower coil 28 outages, valve rod 8 guarantees to be in the extreme higher position with moving assembly under the suction of upper magnetic steel 19; Go up moving iron core 14 and be in attracting state with last static iron core 16; Owing to move on the moving iron core 12 down, following moving iron core 12 is big with following static iron core 11 distances, so suction is very for a short time not to have an effect to lower magnetic steel 29 moving down between iron core 12 and the following static iron core 11.
When valve will be closed, give last coil 21 energisings, give motor stator 23 energisings, along with last coil 21 energisings, it produces magnetic field and upper magnetic steel 19 magnetic field cancellation, and suction disappears between last static iron core 16 and the 1 moving iron core 14; Motor stator 23 passes to the opposite threephase AC of threephase AC phase place when passing to valve opening, motor stator produces magnetic field, and under the effect of shifting magnetic field, motor moves son 13 and produces induction current, and induction current produces under the action of a magnetic field and moves down magnetic force; Under gravity and mobile magnetic force, moving assembly drives valve rod 8 and moves down.Valve rod 8 lower ends are provided with the Sealing of secondary valve; Along with valve rod 8 moves down; The Sealing and the auxiliary-seat of valve rod 8 lower ends are contacted; The Sealing and the main valve seat of valve cup 7 lower ends contact, and move son 13 at deadweight and motor and move and overcome valve rod 8 under the magnetic force and move surface friction drag and make main valve sealing pair 4, and secondary valve seal pair 3 reaches sealing.This moment, medium flowed to part 31 in the lumen, lumen top 30 and air gap 15 through gap between damping hole 32, valve cup 7 and the valve gap 10; Pressure medium in part 31 in the lumen, lumen top 30 and the air gap 15 is risen gradually; Simultaneously cavity of resorption 1 medium of valve body 9 through outlet plenum 5 to outflow; The cavity of resorption 1 medium pressure of valve body 9 descends gradually, then the upper and lower medium pressure difference of main valve sealing pair 4, secondary valve seal secondary 3 form gradually, under the effect of pressure medium difference; Main valve, secondary valve seal property are better, valve closing.Behind the valve closing; Under the control system effect, motor stator 23 outages, last coil 21 outages; Valve rod 8 guarantees to be in extreme lower position with moving assembly under the suction of lower magnetic steel 29; Make main valve sealing pair, the secondary sealing force of secondary valve seal keep certain value, moving iron core 12 is in attracting state, valve continuation place closed condition with following static iron core 11.
With respect to existing technology, the major advantage of the utility model comprises:
(1) it is relevant with power of motor that motor moves son 13 mobile magnetic force; And it is irrelevant with its running length; So it is irrelevant with air gap 15 sizes that motor moves son 13 mobile magnetic force, the bore of tube valve does not have much, air gap how long to have, and valve rod moves the open and close that can both realize valve under the son driving at motor.
(2) motor moves and has moved driving force on the son, and moving down also has driving force, so have two driving action.
(3) valve opening, close after, coil and motor stator all need not the energising, energy-conservation.
What (4) main valve sealing pair and secondary valve seal were secondary cooperatively interacts; Reduced the required driving force of valve rod significantly; Not only reduced the particularly power requirements of linear electric motor device of Electrical heads each several part thus, but also more effectively solved the valve opening under big pressure, the big flow and closed difficult problem.
(5) solenoid valve being difficult for making large bore valves becomes big smaller diameter valve and can both do.
The utility model alleged " on ", D score is relative position; Only be used to the facility explained; Be not used in the actual restriction of using the orientation of this solenoid valve; Because can driving and can adopt separately or cooperate through the linear electric motor device, the valve rod in the utility model adopt the power-on and power-off magnetic device to drive; The deadweight action direction that can overcome or remedy thus because of using the orientation to cause changes the negative effect that brings, but as optimal way, can with described in the utility model specification " on ", the D score direction serve as in the actual use upper and lower to.
