Under the control of PLC control system, water supply electromagnetism water control valve is opened, and water supply installation is supplied by vaporizer
Water pipe road direction vaporizer carries out moisturizing, when the water level of vaporizer reaches the higher limit of water level settings, liquid
Position device detects water level higher limit signal, and is sent by higher limit signal to PLC control system, and PLC controls
System sends control signal and makes heating controller energising work, and the heat that heating controller produces is the most right
Pure water within vaporizer heats, and during heating, water moderate pressure will gradually rise, directly
To producing steam, the pressure of steam relies primarily on pressure transducer and chuck cavity pressure table carries out data acquisition
Collection, and be controlled by regulator, when temperature sensor detects that temperature reaches 134 DEG C, at PLC
Under the control of control system, heating controller disconnects, the heating controller energising fortune when temperature is less than 133 DEG C
OK, so remain that the temperature of vaporizer is in set point.When the pressure in chuck intracavity portion is higher than upper
During limit value, relief valve will automatically spring open under the effect of PLC control system and carry out safety relief, when chuck chamber
When internal pressure is less than lower limit, PLC control system automatic-closing safety valve, it is provided with the main of relief valve
Purpose is the pressure security of protection vaporizer.And the steam of vaporizer is by steam (vapor) outlet directly and chuck chamber
Being connected, equipment is preheated, when the pressure stability of chuck intracavity exists by the steam being full of whole chuck chamber
During scheduled pressure value, warm is complete, and parcel class sterilizing article can be put into steriliser by staff
Interior room.
After parcel class sterilizing article puts into interior room, close sterile chamber's door body and start sterilizing program.PLC is controlled
System processed controls electromagnetic valve and opens, and water supply installation is carried out in water ring vacuum pump by vacuum pump supply channel
Supplying water, water ring vacuum pump is evacuated by the internal room of vacuum line, and check-valves is opened simultaneously, so that
Steam is discharged from soda pop discharge line after carrying out heat exchange in water ring vacuum pump.When water vapour is through water ring
After vacuum pump, steam temperature reduces, thus water ring return pump is played positive protective effect.
The pressure of interior room is quickly evacuated to-85～-90kPa, and when reaching this pressure, water ring vacuum pump stops
Only work.Now, chuck chamber is opened rapidly to the pneumatic operated valve of the air inlet pipeline of interior room, and steam is rapid
Room in entering, is full of whole interior room by steam.After the pressure of interior indoor rises to 60～70kPa, air inlet
The pneumatic operated valve of pipeline cuts out, and pressure regulator is opened, and the steam of interior indoor is through pressure regulation air inlet pipeline and tune
Extruding air pipe to discharge from interior room, the steam of interior indoor is quickly discharged in soda pop discharge line；When
When steam is down to 20kPa, now pressure differential is more and more less, in such a state, relies on increasingly
The steam that little pressure differential is discharged will become fewer and feweri, when the pressure transducer of interior indoor detects
When pressure in interior room is 20kPa, PLC control system sending control signal, make pressure regulator close, water
Ring vacuum pump starts, and such positive and negative pumping processes repeated as above can (concrete number of times be by grasping with 3 circulations
Make personnel setting, it is therefore an objective to allow high-temperature steam can penetrate the inside of sterilizing objects, really play thoroughly
Sterilisation of objects killing effect effect), following pneumatic operated valve is opened rapidly, the most again allows the steaming of chuck layer
Vapour enters interior room.When the pressure of interior indoor rises to and stable 206～210kPa, and temperature is at 134 DEG C
～135 DEG C, maintain 10～12min；Period opened every 30 seconds-40 seconds pressure regulator moments, it is therefore an objective to will
Condensing water droplet a small amount of in interior room is rejected in soda pop discharge line, makes the sterilizing article in interior room to go out
Existing wet bag, such process is behind 10～12min, and sterilization process completes.
After sterilization process completes, opening pressure regulator, the steam of interior room is through pressure regulation air inlet pipeline and tune
Extrusion air pipe is discharged, and when the pressure of interior room is down to 10kPa, terminates aerofluxus.
Opening water ring vacuum pump, the sterilizing objects in internal room is fully dried, and sterilizing objects is at high temperature
In vacuum environment, the steam on sterilizing objects is evaporated rapidly, thus plays article desiccation.
When vacuum state keeps 6～8min, and dry run terminates, and water ring vacuum pump is out of service.Pneumatic corner valve is opened
Open, entered into the interior indoor of sterile chamber through the pure air of filter by filter pipeline, so that interior
Indoor pressure recovers to atmospheric pressure.When pressure and the atmospheric pressure balance of interior indoor, whole disinfecting process
Terminate, the most just can open sterile chamber's door body and take out sterilizing objects.
Steam raising plant the most of the present utility model is connected with the chuck chamber of sterile chamber, and takes out true
Empty device is connected with the interior room of sterile chamber, and chuck chamber is connected with interior room by air inlet pipeline, in air inlet
Pipeline is provided with pneumatic operated valve, housing is provided with for control steam raising plant, vacuum extractor and
The PLC control system of pneumatic operated valve, utilize PLC control system to steam raising plant, vacuum extractor and
Pneumatic operated valve effectively controls, it is possible to make the interior chamber pressure of the pulse vacuum vapor sterilization machine obtain effectively
Control, thus effectively raise the effect of this pulse vacuum vapor sterilization machine sterilizing and use safety.
Of the present utility model ultimate principle, principal character and of the present utility model excellent have more than been shown and described
Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned
Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description
On the premise of spirit and scope, this utility model also has various changes and modifications, and these changes and improvements are all
In the range of falling into claimed this utility model.This utility model claims scope by appended right
Claim and equivalent thereof define.
