Description
Technical field
This utility model relates to a kind of isolator cabin inside and outside differential pressure regulator control system, and in belonging to the cabin of isolator, pressure reduction controls
Field.
Background technology
Isolation technology is the technology that controlled space and external environment condition are mutually completely cut off by a kind of means using physical barriers.?
When isolator produces or detects, according to medicine in cabin or the toxicological characteristics of article to be tested, when there is leakage to protect medicine
When being main and harmless, need in isolator to remain malleation, when occur leakage time harmful thus with protection
When personnel are main, need in isolator to remain negative pressure.It addition, be sometimes also required to keep in the zones of different within isolator
Different pressure reduction, to avoid cross-contamination each other.It can be said that pressure reduction can be regulated accurately, it is to isolator performance
Big appraisal standards.
Utility model content
The purpose of this utility model is to provide a kind of isolator cabin inside and outside differential pressure regulator control system, it is possible to accurately regulate isolation
Device nacelle inside and outside differential pressure, meets isolator application demand.
Isolator cabin described in the utility model inside and outside differential pressure regulator control system, including isolator nacelle, isolator nacelle
Being provided with air intake blower fan, exhaust fan and pressure difference transmitter, air intake blower fan, exhaust fan and pressure difference transmitter connect control respectively
Device, controls device for controlling the rotating speed of air intake blower fan and exhaust fan to adjust the pressure reduction inside and outside isolator nacelle, pressure reduction
Transmitter is for detecting the inside and outside differential pressure of isolator nacelle and transferring data to control device.
Pressure difference transmitter gathers isolator nacelle inside and outside differential pressure, and is transported to the data of collection control device, controls dress
Put according to the Data Control air intake blower fan gathered and exhaust fan, keep pressure reduction suitable inside and outside isolator nacelle.
It is further preferred that isolator nacelle is provided with proximity switch, proximity switch is for detecting the close of isolator nacelle
Sealing up a door and close situation, proximity switch connects control device.Proximity switch is used for detecting isolator nacelle hermatic door and closes situation.
It is further preferred that controlling device is that PLC controls device.
Compared with prior art, the beneficial effects of the utility model are:
(1) this utility model is by arranging pressure difference transmitter, air intake blower fan and exhaust fan and control device, controls dress
Put by controlling air intake blower fan and the rotating speed of exhaust fan, it is achieved that the adjustment to isolator nacelle inside and outside differential pressure, meet every
From device application demand；
(2) pass through to be positioned proximate to switch and close situation for detecting isolator nacelle hermatic door, keep isolation as required

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further:
As it is shown in figure 1, isolator cabin described in the utility model inside and outside differential pressure regulator control system, including isolator nacelle 1,
Isolator nacelle 1 is provided with air intake blower fan 5, exhaust fan 6 and pressure difference transmitter 3, and air intake blower fan 5, exhaust fan 6 and pressure reduction become
Send device 3 to connect control device respectively, control device for controlling the rotating speed of air intake blower fan 5 and exhaust fan 6 to adjust isolator
Pressure reduction inside and outside nacelle 1, pressure difference transmitter 3 is for detecting the inside and outside differential pressure of isolator nacelle 1 and transferring data to control device.
Isolator nacelle 1 is provided with proximity switch 2, and proximity switch 2 closes situation for the hermatic door detecting isolator nacelle 1, close
Switch 2 connection controls device.Controlling device is that PLC controls device 4.
Work process or operation principle:
Pressure difference transmitter 3 gathers 1 external differential in isolator nacelle, and is transported to the data of collection control device, controls
Device, according to the Data Control air intake blower fan 5 gathered and exhaust fan 6, keeps pressure reduction suitable inside and outside isolator nacelle 1.
When system is run, PLC controls device 4 and gathers the setting value of actual pressure differential and the pressure reduction come according to pressure difference transmitter 3
Comparing, if actual pressure differential is less than setting pressure reduction, then PLC controls device 4 and controls air intake blower fan 5 and increase speed, and reduces row
Wind blower fan 6 rotating speed；If actual pressure differential is more than setting pressure reduction, then PLC controls device 4 and controls exhaust fan 6 and increase speed, and reduces
The rotating speed of air intake blower fan 5；According to gathering the real-time pressure reduction come, system is fed back, it is achieved that the PID of pressure reduction controls.
After proximity switch 2 detects that hermatic door is opened, if isolator nacelle 1 is negative pressure running status, then PLC controls
Device 4 can control increasing exhaust blower fan 6 rotating speed, reduces air intake blower fan 5 rotating speed, there to be bigger bearing in keeping isolator nacelle 1
Pressure, if isolator nacelle 1 is operation under positive pressure state, then PLC controls device 4 and can control to increase air intake blower fan 5 rotating speed, reduction row
Wind blower fan 6 rotating speed, there to be bigger malleation in keeping isolator nacelle 1.
Direction and the description of relative position relation to structure in this utility model, such as the most upper and lower description,
Do not constitute restriction of the present utility model, the most for convenience of description.
