Numeral and the corresponding component title represented by letter in figure:
1. cabinet 2. baroceptor 3. controller 4. inflator pump 5. air pump
6. air inlet 7. venthole 8. admission line 9. outlet pipe 10. display screen
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
This utility model provides air pressure protection type ring main unit, and its operation principle is to improve gas in cabinet by inflator pump
Pressure, utilizes air pump to reduce cabinet internal gas pressure, reaches meet hyperbar and hypobaric use requirement simultaneously and reduce enterprise
The purpose of production cost.
Below in conjunction with embodiment and detailed description of the invention, this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of air pressure protection type ring main unit, include cabinet 1, described cabinet 1 is internal is provided with detection
The baroceptor 2 of ring main unit internal gas pressure, for filling the aerating device of the gas in ring main unit and within getting rid of ring main unit
The exhaust apparatus of gas, described baroceptor 2 connect have controller 3, described aerating device to include inflator pump 4, described in fill
Air pump 4 is connected with described controller 3；Described exhaust apparatus includes air pump 5, described air pump, 5 and described controller 3
Realize connecting.
It should be noted that described cabinet is provided with air inlet 6 and venthole 7, described air inlet 6 and described inflator pump 4
Realizing connecting by admission line 8, described venthole 7 realizes being connected by outlet pipe 9 with described air pump 5.
It should be noted that described controller is also associated with display screen 10, described display screen is arranged on described cabinet.
It should be noted that described baroceptor is placed in the top inner wall of described cabinet.
It should be noted that the connection of described controller has cabinet door lock, described cabinet door lock to be placed on the cabinet door of described cabinet.
It should be noted that described air pump and inflator pump are symmetricly set on the two bottom sides of described cabinet.
Specifically used step of the present utility model is as follows: the most as depicted in figs. 1 and 2, during actual use, and air pressure
Air pressure is also constantly vertically fed back to controller 3 by the air pressure in the continuous detecting box of sensor 2, when finding that air pressure is too low, controls
Device controls inflator pump 4 and opens, and closes air pump 5, and inflator pump 4 is filled with other to increase by air inlet 6 and admission line 8 in cabinet
Add the air pressure in cabinet it is known that meet the needs of production；When detecting that air pressure is too high, controller 3 controls air pump 5 and opens, and
Closing inflator pump 4, air pump 5 gets rid of the air in cabinet, to reduce the air pressure in cabinet by venthole 7 and outlet pipe 9.Opening
Opening inflator pump 4 or open while air pump 5, cabinet door is closed by controller switch board door lock, prevent from regulating again air pressure time
Wait staff and open cabinet door, it is to avoid staff comes to harm.Meanwhile, the air pressure that baroceptor 2 is also transmitted by controller 3
Numerical value is shown by display screen 10, can be convenient for people to the air pressure situation knowing in cabinet.
