When leak function, and have electromagnetic door lock function at closing time.Common gas-tight door relies on door electromagnetic lock electromagnetic attraction and door sealing
Expansion sealing locking door.The inflation swelling of gas-tight door closing back door sealing strip is chronically at air-tight state, gas circuit in actual use
It can leak slowly, insufficient pressure will reduce Expansion sealing performance in door weather strip, and adjacent room has a possibility that connection.
Summary of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, providing automatic air-compensating type air gas-tight door, also provide
Airtight door control method.Gas pressure in real time on-line monitoring door weather strip is automatically performed benefit when hypotony in sealing strip
Gas work, maintains the pressure of door weather strip on setting value always, guarantees that gas-tight door is in the tight sealing state of expansion, solution always
The problem of airtight door closed of having determined declines naturally.
In order to achieve the above object, the present invention provides following technical schemes:
Automatic air-compensating type air gas-tight door, the door weather strip of the door leaf periphery including gas-tight door is arranged in, further include gas source, charge valve and
Vent valve, gas channels one end connection in the gas outlet and charge valve of gas source, the gas channels other end and door in charge valve
The charge and discharge port of sealing strip connects, and the charge and discharge port of gas channels one end and door weather strip in vent valve connects, door weather strip
Charge and discharge port be additionally provided with second pressure detection module, the gas outlet of gas source is provided with first pressure detection module, charge valve
Control terminal, the control terminal of vent valve, door open button and door close button connect respectively with controller, controller also with setting exist
The coil module of electromagnetic lock on doorframe connects, controller also with connecting on doorframe close to switch is set.
Airtight door control method, specifically:
Step 1.1 presses door open button, and door open button sends opening signal to controller;
After step 1.2, controller receive opening signal, the gas supply of the gas outlet of gas source is detected by first pressure detection module
Pressure obtains supply gas pressure signal, and supply gas pressure signal is sent controller by first pressure detection module;
Step 1.3, controller judge the size of supply gas pressure signal and setting supply gas pressure threshold value,
If supply gas pressure signal is more than or equal to setting supply gas pressure threshold value, controller controls the gas channels in charge valve and closes,
The gas channels that controller controls in vent valve are open-minded, and gas in door weather strip is by the gas channels in vent valve to leaking
Gas, lose heart setting time after, controller control vent valve in gas channels close, controller control electromagnetic lock coil module
Power loss, controller control instructions lamp are door opening state, pull open gas-tight door manually;
If supply gas pressure signal is less than setting supply gas pressure threshold value, controller controls the gas channels in charge valve and closes, control
Device controls the gas channels in vent valve and closes, and controller control instructions lamp is malfunction.
Airtight door control method further includes shutdown step, specifically:
Step 2.1, the door leaf for closing gas-tight door manually, close to switch output activation signal to controller, electromagnetic lock output locking
Signal closes gate signal to controller, activation signal and block signal composition,
Step 2.2, controller receive close gate signal after, controller control charge valve in gas channels it is open-minded, controller control
Gas channels in vent valve are closed, and gas source is inflated by the gas channels in charge valve to door weather strip, inflate setting time
Afterwards, the gas channels in controller control charge valve disconnect, and the controller record inflation end time, controller control instructions lamp is
Shutdown state;
Step 2.3 obtains sealing strip pressure by the sealing strip pressure in second pressure detection module real-time monitoring door weather strip
Sealing strip pressure signal is transmitted to controller by signal, second pressure detection module;
Sealing strip pressure signal is compared by step 2.4, controller with setting sealed pressure threshold value:
If step 2.5, sealing strip pressure signal are more than or equal to setting sealed pressure threshold value, return step 2.4;
If sealing strip pressure signal is less than setting sealed pressure threshold value, current time and recent inflation end time are calculated
Between difference obtain inflation interval time,
If inflating interval time is more than or equal to setting interval threshold, the gas channels that controller 7 controls in charge valve are open-minded, control
