Description of drawings
Fig. 1 is the cross-sectional top view by magnetic valve;
Fig. 2 is the interface top view by electromechanical valve.
The specific embodiment
As shown in Figure 1, steam pressurized steaming plant 1 comprises valve cell 2, the steam (vapor) outlet opening 3 that this valve cell can steam off pressure cooking device 1 inner space 4.In this preferred implementation, this valve cell 2 uses as magnetic valve.This valve cell 2 comprises coil 5 and ferromagnetic core 6.By capping 7, this steam (vapor) outlet opening 3 can be closed, and escapes from from steam (vapor) outlet opening 3 thereby no longer include steam.Randomly, described electromagnetic valve unit 2 position equally endways comprises two permanent magnets 8,8 ', and this terminal position is the terminal position with respect to ferromagnetic core 6 and/or resetting spring (resetting spring) 9.
If between the on-stream period of electromagnetic valve unit 2, electric current flows through coil 5, and it will set up electromagnetic field.Restrain (bundle) simultaneously on the other hand by ferromagnetic core 6 on the one hand by this electromagnetic field that coil 5 produces, the elementary magnet of ferromagnetic core 6 will himself be oriented in the magnetic field that is produced by coil 5, thereby these ferromagnetic core 6 same becoming have magnetic, and thereby have magnetic pole on its two ends 10,10 '.Can change by the galvanic reversal that links to each other with coil 5 in the two ends 10 of ferromagnetic core 6, the direction of 10 ' magnetic pole.
If permanent magnet 8,8 ' has the axial magnetic sexual orientation now, simultaneously permanent magnet 8,8 ' magnetic pole are right against the end 10,10 ' of ferromagnetic core 6, so, go up the magnetic pole that produces by coil 5 at ferromagnetic magnetic core 6 ends 10,10 ' and also be used for producing attraction or repulsive force.Thus, based on the orientation of ferromagnetic magnetic core 6 magnetic poles, the valve cell 2 relevant with its capping 7 can be placed to upper/lower positions, and promptly steam (vapor) outlet opening 3 can close or open by capping 7 on this position, and wherein capping 7 links to each other with ferromagnetic core 6.Owing to there is permanent magnet 8,8 ', to set up not activating coil 5 under the situation in magnetic field of magnetization ferromagnetic core 6, ferromagnetic core 6 is fixed on in these positions one.
If only in order to change the position, also need to be supplied to coil 5 electric currents, this is owing to the attraction that need overcome between permanent magnet 8,8 ' and terminal 10,10 '.Thus, the polarity of the ferromagnetic core 6 that is caused by coil 5 is so selected, and promptly endways between 10,10 ' and permanent magnet 8,8 ' between self, has produced repulsive force, and wherein terminal 10,10 ' links to each other with permanent magnet 8,8 ' magnetic.Therefore, ferromagnetic core 6 change to other position simultaneously another permanent magnet 8,8 ' link to each other with another end 10, the 10 ' magnetic of ferromagnetic core 6.After ferromagnetic core 6 changes to another position from a position, just no longer needed the supply of electric power of coil, this is because the position that ferromagnetic core 6 can remain on separately by permanent magnet 8,8 ' separately.
In preferred embodiment, position change process starts by measurements/control and adjusting device, is at first led to direct current at the coil 5 of required polarization state separately in this installs.What can expect here is, measurement/control for example links to each other with pressure sensor with adjusting device, reaching or surpassing when opening the critical value of pressure, makes electromagnetic valve unit enter open position.Next local decompression (depressurisation) or reach the critical value that is used for closing presure, valve cell 2 can be returned to the closed position by measurement/control and adjusting device.This bistable embodiment of electromagnetic valve unit 2 is particularly preferred, and this is owing to the terminal position separately at valve cell 2, flows through coil 5 thereby does not use any energy without any electric current.
In other embodiments, can only use in the permanent magnet 8,8 ' one.This will be the monostable pattern of electromagnetic valve unit 2.No matter monostable or under the bistable design, end 10 ' and the attraction between the permanent magnet 8 ' in ferromagnetic core 6 can be selected, thereby make that ferromagnetic core 6 can change its position from closing to always between the open position according to the preset value of the internal pressure of steam pressurized steaming plant 1.By this configuration of permanent magnet 8 ' and iron core 6, can guarantee the pressure protect of steam pressurized steaming plant 1.
In other bistable embodiment; pressure protect and closed position all produce by resetting spring 9; permanent magnet 8 changes maintaining valve unit, back at open position a position simultaneously, and permanent magnet 8 ' is optional in the present embodiment, therefore can not install.
According to Fig. 2, a kind of electromechanical valve unit 2 ' comprises electric drive 11, and screw thread 12 and two-stage or multi-stage gear 13, this screw thread are used for spinning movement is converted to the stroke action.Also there are capping 7 and optional terminal stops (end stop) 14 similarly.By this design, going out flow section and can regulate in steam (vapor) outlet opening 3 zone with arbitrary dimension.This embodiment also has low energy consumption, and this is because electric drive 11 only needs the short time operation in each case.By screw thread 12 and transmission device, the stroke movement of capping 7 can be extraly accurately regulated the stable position that can be fixed of capping 7 simultaneously, and this transmission device for example is worm gear drive.Terminal stops 14 has limited the maximum open position of capping 7.Because in this case; valve cell 2 ' may be difficult to the pressure suddenly in the inner space 4 is increased in the suitable time makes a response; therefore in the preferred embodiment of steam pressurized steaming plant; must be provided for the protective device of steam decompression in addition; wherein; when the internal pressure in inner space 4 for example was higher than 1.5bar, the valve of protective device was opened.
In the preferred implementation of boiling usefulness method, can set critical value by the measurement/control and the adjusting device of pressure-regulating device, this boiling is carried out under steam pressure in steam pressurized steaming plant 1, this critical value is used at least one and opens pressure and/or at least one closing presure, wherein pressure-regulating device comprises valve cell 2,2 ', thereby this measurement/control and adjusting device keep internal pressure in default critical value.This opening and closing pressure no longer is fixed against the geometrical condition and the steam (vapor) outlet opening 3 of capping 7, but default by critical value, and this critical value is set by measurement/control and adjusting device.Thereby, can be set to geometrical condition and the steam (vapor) outlet opening 3 that is independent of capping 7 as required by closing presure and the hysteresis of opening the pressure realization.
In fact, thus use the malleation of this valve cell in steam pressurized steaming plant inner space in the steam pressurized steaming plant, to regulate between 0bar or the 0.5bar to 1.5bar.The blast of steam pressurized steaming plant is used to avoid the protective device of explosion danger to provide as the part of pressure-regulating device during for fear of the pressure on being higher than 1.5bar.The advantage of using described boiling method is corresponding to opening pressure and closing presure critical value, and boiling temperature at interval can be by measurements/control and adjusting device setting.Thereby based on the setting of opening pressure and closing presure, this boiling temperature can be determined at interval by corresponding boiling temperature.If because excessive temperature supply, the temperature in the inner space 4 of steam pressurized steaming plant 1 has increased, and the pressure in the inner space 4 of steam pressurized steaming plant 1 also can raise.In case this pressure reaches the critical value that is used to open pressure, this valve cell 2,2 ' is opened steam (vapor) outlet opening 3, thereby can avoid the extra pressure in inner space 4 to increase.If 4 these pressure have descended at open position in the inner space, in case reach the closing presure critical value, this valve cell 2,2 ' just can steam off exit opening 3.Because in this system, the pressure in the inner space 4 is also corresponding to temperature in each case, the boiling temperature in steam pressurized steaming plant 1 remains in the boiling temperature interval, and this boiling temperature is determined with critical value by opening pressure and closing presure at interval.
According to Fig. 1 and 2, utilize described method, the position of valve cell 2 cappings 7 is preferably by electric power and/or mechanical force and/or aerodynamic force change.In the embodiment of Fig. 2, the open position of capping 7 can be carried out following setting, promptly by the open position of capping 7, can set the steam rate of release of steam pressurized steaming plant 1.In this article, steam discharges escaping of the steam mean by valve cell 2.
