Equipment.
, using being all POCl3 distributing feed flow, every bottle of 2.5L POCl3 is probably available for Jie Jia wound tubular type diffusion facilities
One-month period, change POCl3 Comparision frequently, and adopt the DS300A diffusion furnace of distributing feed flow changing at present
During the bottled POCl3 of 2.5L, employing is all valve to be opened manually and confirms valve switch.
If operating personnel's error air inlet gas outlet valve be not turned on or gas circuit in pressure anomaly, equipment nor send out
Now abnormal, ultimately result in the increasing danger having bottled explosion of bottled interior pressure of POCl3.
So, how to provide the photovoltaic cell with protection device to spread source, solve presence in bottle replacing in source in prior art
Problem, be current those skilled in the art technical problem urgently to be resolved hurrily.
Utility model content
In view of this, the utility model provides a kind of diffusion of the photovoltaic cell with protection device source, solves prior art
Present in defect, concrete scheme is as follows：
A kind of diffusion of the photovoltaic cell with protection device source, including source bottle, described source bottle is provided with intake valve, air outlet valve,
Described intake valve is connected with inlet end by magnetic valve, and described air outlet valve is connected to outlet side by check valve, described magnetic valve
Control end be connected with PLC, described PLC is connected with the industrial computer of equipment,：Intervalve in described magnetic valve and described intake valve
It is also associated with pressure sensor, described pressure sensor is connected with described PLC communication, and described industrial computer is additionally provided with warning on road
Device.
Further, the intermediate duct of described magnetic valve and described intake valve is also associated with waste valve, described waste valve
It is connected with waste discharge end.
Further, described waste valve is battery valve, and the control end of described waste valve is connected with described PLC communication.
Preferably, warning device is acoustic-optic alarm.
Preferably, described source bottle is 2.5L, is installed in prompt good wound DS300A type tubular type diffusion facilities.
The utility model compared with prior art, this have the advantage that：1st, improve safety coefficient when source bottle is changed.
