Description
Technical field
This utility model relates to a kind of gas sealing mechanism for isolator seal door sealing, belongs to isolator equipment and technology
Field.
Background technology
At present, sterile production that isolator is widely used in pharmaceutical industry and sterility test, owing to isolation isolator allows
It is placed in D level environment, and in isolator, carries out high risk operation, thus the tightest to the seal request of isolator
Lattice.And hermatic door is due to needs open and close, so the sealing of hermatic door is the most important thing of isolator seal, and isolator
After hermatic door is closed, inside isolator, carry out the medicinal liquid medicine meeting of VHP sterilizing and various production operation, sterile medium and production
Touch and sealing joint strip under sealing joint strip, certain situation, can be made to be a bit sticky, switch gate can be made very inconvenient.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide one for every
The gas sealing mechanism sealed from device hermatic door, simple in construction, easy to use, can ensure that isolator seal again can while good
During hermatic door open and close the most smooth and easy.
Gas sealing mechanism for isolator seal door sealing described in the utility model, including isolator nacelle, isolation
Device nacelle is provided with hermatic door, and in isolator nacelle, the junction with hermatic door is provided with gas-flow closure bar, right in isolator nacelle
Hermatic door position is answered to be provided with proximity switch；Gas-flow closure bar connects source of the gas by gas piping, and gas piping was sequentially provided with
Filter air relief valve, vacuum generator, electromagnetic valve, pressure switch.
When hermatic door is closed, proximity switch detects that hermatic door is closed and puts in place, and system gives inflation adhesive tape inflation automatically, it is achieved
The sealing of hermatic door.Inside isolator after VHP sterilizing and various operation produce, inflation adhesive tape is made to have certain sticking sometimes
Property, when hermatic door is opened, electromagnetic valve venting vacuum generator work simultaneously makes to be in inside inflation adhesive tape vacuum state, and adhesive tape is complete
Total detachment hermatic door, it is achieved hermatic door is opened flexible, will not damage again sealing joint strip simultaneously.
Preferably, on hermatic door, connection has air spring one end, the air spring other end to be connected in isolator nacelle, for close
Seal up a door open after support.
Preferably, hermatic door is safety glass, is i.e. easy to portion in astrodome body, the most elegant in appearance.
Preferably, electromagnetic valve is two-position-five-way solenoid valve.
Preferably, safety glass thickness 15mm.
This utility model is compared with prior art had the beneficial effect that
For the gas sealing mechanism compact conformation of isolator seal door sealing, easy to use and flexible, close owing to being provided with
Switch and vacuum generator, it is achieved that when hermatic door is closed, close the automatic inflating that puts in place and seal, and during unlatching, gas-flow closure bar is complete
Departing from hermatic door, hermatic door is opened will not damage again sealing strip flexibly and easily.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, the gas sealing mechanism for isolator seal door sealing includes isolator nacelle 10, isolation
Device nacelle 10 is provided with hermatic door 7, and in isolator nacelle 10, the junction with hermatic door 7 is provided with gas-flow closure bar 6, isolator cabin
On body 10, corresponding hermatic door 7 position is provided with proximity switch 9；Gas-flow closure bar 6 connects source of the gas 1, gas piping by gas piping
On be sequentially provided with filtering pressure reducing valve 2, vacuum generator 3, electromagnetic valve 4, pressure switch 5.
Connecting on hermatic door 7 has air spring 8 one end, air spring 8 other end to be connected in isolator nacelle 10.
Hermatic door 7 is the safety glass that 15mm is thick.
Electromagnetic valve 4 is two-position-five-way solenoid valve.
Work process: when hermatic door 7 is closed, proximity switch 9 detects that hermatic door 7 is closed and puts in place, two-position five-way electromagnetism
Valve 4 is opened, and is led to by the compressed gas that filtering pressure reducing valve 2 reduced pressure to gas-flow closure bar 6, gas-flow closure bar 6 gas-flow closure hermatic door 7
15mm thickness tangent plane, it is achieved hermatic door 7 seals, and in the process, pressure switch 5 can monitor leads to the compression of gas-flow closure bar 6
Gas pressure, again not over the work pressure of gas-flow closure bar 6 while making compression pressure guarantee hermatic door 7 to reveal
Power.
When hermatic door 7 is opened, door open button is clicked in manual operation, and two-position-five-way solenoid valve 4 is exitted, and vacuum occurs simultaneously
Device 3 works, and makes gas-flow closure bar 6 inside be in vacuum state, and now gas-flow closure bar 6 completely disengages from hermatic door 7, manual-up
Opening hermatic door 7, after hermatic door 7 is opened, hermatic door 7 can be supported by air spring 8, it is ensured that hermatic door 7 is in opening.
