Description
Technical field
The present invention relates to technical field of medical equipment, and in particular to a kind of unqualified medical air reflux.
Background technology
Unqualified medical air reflux is mainly used in the processing gas outlet of medical air compressor group, and the device is main
With the outlet of qualified gas, the backflow of unqualified gas and manual emptying (standby) three functions.And medical air compressor group is to be big
The medical gas central station of Medium Sized Hospitals provides medical air source of supply and hospital's part Medical Devices provide aerodynamic force source of the gas.Mirror
In this, it certainly will need to design the air quality of processing gas outlet of the device to ensure medical air compressor group, it is ensured that qualified
Air, which enters, uses gas point, and unqualified air, which is forbidden to enter, uses gas point, and common unqualified air is directly vented and wastes very much money
Source, processing is deepened until qualified just more reasonable by unqualified air return into medical air compressor group.
The content of the invention
To solve the above mentioned problem that prior art is present, the present invention is intended to provide a kind of unqualified medical air backflow dress
Put, the reflux should ensure that up-to-standard air output, and can effectively reduce the wasting of resources, also with structure letter
Single, easy to use technical characterstic.
To achieve these goals, the present invention is adopted the following technical scheme that：
Unqualified medical air reflux, it is characterised in that：The backflow connected including air inlet pipe fitting and with it is taken over, gone out
Detecting element is provided with gas adapter, emptying adapter, air inlet pipe fitting, a stop valve is provided with the adapter that flows back and No. one pneumatic
It is provided with valve, outgoing gas connection tube in No. two stop valves and No. two pneumatic operated valves, emptying adapter and is provided with manual ball valve.
Preferably, the detecting element includes pressure transmitter, dew point transmitter and carbon monoxide transmitter.
The beneficial effects of the invention are as follows：The present invention can detect air quality, it is ensured that acceptable air, which enters, uses gas point, will not
Acceptable air is back to in-depth in equipment and handled, so as to economize on resources, reduces cost, and simple in construction, easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited in following examples.
As shown in figure 1, the unqualified medical air reflux that the present invention is provided, it is characterised in that：Including air inlet pipe fitting 1
And backflow adapter 2, outgoing gas connection tube 7, the emptying adapter 8 connected with it, detecting element, backflow adapter 2 are provided with air inlet pipe fitting 1
On be provided with a stop valve 3 and a pneumatic operated valve 4, outgoing gas connection tube 7 and be provided with No. two stop valves 5 and No. two pneumatic operated valves 6, put
Manual ball valve 9 is provided with empty adapter 8.The detecting element includes pressure transmitter 10, dew point transmitter 11 and carbon monoxide
Transmitter 12.
Air inlet pipe fitting 1 and the processing gas outlet of medical air compressor group are connected, and outgoing gas connection tube 7 is returned with being connected with gas point
Flow adapter 2 and the air inlet of medical air compressor group is connected.Number stop valve 3, pneumatic operated valve 4, No. two stop valves 5, two
Number pneumatic operated valve 6, pressure transmitter 10, dew point transmitter 11 and carbon monoxide transmitter 12 with medical air compressor group can
Programmable controller (PLC) is connected.
The present invention operation principle be：
1st, unqualified medical air reflux is arranged on the processing gas outlet of medical air compressor group, is become using pressure
Device 10, dew point transmitter 11, the acquisition process gas signal of carbon monoxide transmitter 12 are sent, is transmitted by 4~20mA analog signalses
Programmable controller (PLC) to medical air compressor group is analyzed, judges whether air source quality is qualified；
2nd, when pressure, dew point, three indexs of carbon monoxide are qualified, PLC sends instruction and closes a pneumatic operated valve 4, together
When open No. two pneumatic operated valves 6, on the premise of No. two stop valves 5 are opened in advance, acceptable air connects by air inlet pipe fitting 1, outlet
Pipe 7, No. two stop valves 5, No. two pneumatic operated valves 6 (gas open form) enter with gas point (being generally introduced into air accumulator)；
3rd, when pressure, dew point, three indexs of carbon monoxide have one it is unqualified when, PLC does not send instruction, now a gas
Dynamic valve 4 (gas-tight type) normality is opened, while No. two pneumatic operated valve 6 (gas open form) normalities are closed, is opened in advance in a stop valve 3
Under the premise of, unqualified air is by air inlet pipe fitting 1, backflow adapter 2, stop valve 5, pneumatic operated valve 4 (gas-tight type) backflow
Pipeline in-depth processing to medical air compressor group is until qualified output；
4th, just used when emptying adapter 8 is dedicated air outlet, only each operated pneumatic valve operational failure, it is ensured that equipment is pacified
Entirely.
Finally it should be noted that the invention is not restricted to above example, can also there is many variations.This area it is general
All deformations that logical technical staff directly can export or associate from present disclosure, are considered as the present invention's
Protection domain.
