Equipped with exhaust valve, the cabinet body lateral wall is equipped with microprocessor, the signal output end of the differential pressure pick-up and microprocessor
Signal input part connection, the signal output end of the microprocessor connect with the signal input part of flow control valve and exhaust valve respectively
It connects.
In one embodiment, the gas tank is connect by bolt assembly with cabinet body.
In one embodiment, the microprocessor is connect by mounting base with cabinet body.
In one embodiment, protective cover is equipped on the outside of the microprocessor.
The beneficial effects of the present invention are: guaranteed in cabinet body by pressure difference in detecting box body to control air inlet and exhaust
The safety in portion.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure: 1, cabinet body；2, differential pressure pick-up；3, gas tank；4, air inlet pipe；5, flow control valve；6, exhaust pipe；7, it is vented
Valve；8, microprocessor.
Specific embodiment
Invention is further described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, a kind of electrical control cabinet making-up air device, including cabinet body 1,1 inner sidewall of cabinet body are passed equipped with differential pressure
Sensor 2,1 lateral wall of cabinet body are equipped with gas tank 3, and the gas tank 3 inside air inlet pipe 4 and cabinet body 1 by being connected to, the air inlet pipe
4 are equipped with flow control valve 5, and 1 lateral wall of cabinet body is additionally provided with the exhaust pipe 6 being connected to its inside, sets on the exhaust pipe 6
There is exhaust valve 7,1 lateral wall of cabinet body is equipped with microprocessor 8, the signal output end and microprocessor 8 of the differential pressure pick-up 2
Signal input part connection, the signal output end of the microprocessor 8 signal input part with flow control valve and exhaust valve 7 respectively
Connection.
In the present embodiment, the gas tank 3 is connect by bolt assembly with cabinet body 1.
In the present embodiment, the microprocessor 8 is connect by mounting base with cabinet body 1.
In the present embodiment, protective cover is equipped on the outside of the microprocessor 8.
The present apparatus guarantees the safety inside cabinet body 1 by detection 1 internal pressure differences of cabinet body to control air inlet and exhaust.
A specific embodiment of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.
