Description
Technical field
The present invention relates to a kind of mechanical device, and in particular to the gas flow field device under a kind of closed environment.
Background technology
With continuing to develop for science, experiment of the closed environment in other words in closed container is more and more.To closed container
In environmental requirement it is more and more stricter, relatively common is exactly the development and application of hyperbaric oxygen chamber.At present, into pressure vessel
There is provided gas is all the direct insufflation gas into container or gas is provided into closed container by breathing mask using closed.
For example in hyperbaric oxygen chamber, the normal existence of personnel in container can be ensured using oxygen mask, but other will not use breathing
The biology of mask can not survive.As directly filled gas into container, it is impossible to be accurately controlled, and to the gas in container
Quality and uniformity coefficient are not guaranteed.Above-mentioned technical problem has limited to the use scope of container, and many medical experiments will be unable to
Into or be difficult to complete, plenum system of the prior art is unfavorable for progress and the hair of medical science that closed container tests relevant science
Exhibition.
The content of the invention
The technical problem that can not ensure for the gaseous mass and uniformity coefficient that solve in closed container in the prior art, this hair
It is bright to provide a kind of gas flow field device, gas flow can be formed in closed container, so as to ensure in closed container
Gaseous mass and uniformity coefficient.
Gas flow field device, including new gas source, valve, regulating valve, gas distributor, check-valves, vavuum pump, it is special
Levy and be, controllable valve is installed in the new gas source, for controlling gas to convey or stopping the conversion of feed status, newly
Gas source enters regulating valve after being come out from valve, and the flow velocity and total amount of gas are inputted by governor valve control, and gas passes through regulation
Enter gas distributor after valve, gas distributor is fixedly mounted on the top of closed container, enter for distributing in closed container
The gas flow of diverse location；The gas outlet of closed container is connected by gas conduit with check-valves, the other end of check-valves with it is true
Empty pump is connected, and the interconnection in device is that each several part for making device by gas conduit is connected.
The present invention is filled with the mode of new source of the gas, gas is formed an air pressure in closed container by extracting old gas out
Rotation, because of the presence that air pressure revolves, makes gas form flow gas in closed container, so that realize that gas in closed vessel is uniform,
And old gas is extracted, the new gaseous mass being filled with is controllable, both ensure that the gaseous mass in closed container, while also making closed
Gas in container is uniform.The operating efficiency and implementation quality in science or medical experiment can be greatly improved.The present invention may be used also
Quickly extract old gas out, be filled with new gas, new gas is formed in a device, make the gas in device can be within the shortest time
The high-purity of new gas is realized, the requirement under special marginal test environment is met.
Brief description of the drawings：
The brief description of the drawings of the present invention is as follows：
Fig. 1 gas flow field device structural representations；
The schematic diagram of Fig. 2 closed containers internal structure and gas flow；
The electric control valve 5. of 1. 3. magnetic valve of new 2. orifice flowmeter of wind filter 4. ends in figure
The flexible vacuum of 10. check-valves of joint 11. of 6. gas distributor of valve, 7. silencer, 8. surge tank 9.
The closed container of 12. axial flow blower of pump 13..
Embodiment：
Below in conjunction with the accompanying drawings, the present invention is described further：
Gas flow field device, including new gas source, valve, regulating valve, gas distributor 6, check-valves 10, vavuum pump
11, it is characterised in that controllable valve is installed in the new gas source, for controlling gas to convey or stopping feed status
Conversion, new gas source enters regulating valve after being come out from valve, and the flow velocity and total amount of gas are inputted by governor valve control, and gas leads to
Overregulate and enter gas distributor 6 after valve, gas distributor 6 is fixedly mounted on the top of closed container 13, enter for distributing
The gas flow of diverse location in closed container 13；The gas outlet of closed container 13 is connected by gas conduit with check-valves 10, only
The other end for returning valve 10 is connected with vavuum pump 11, and connected in device is that each several part for making device by gas conduit is connected
Get up.When in use, vavuum pump 11 is opened, then by check-valves 10 and gas conduit by the closed container 13 being attached thereto
Old air is extracted out and discharged；While vavuum pump 11 works, Open valve makes the gas in new source of the gas enter control valve,
Gas flow rate is adjusted by control valve, new gas enters through reallocating into closed container 13 after gas distributor 6, because of gas
Air pressure in body distributor 6 is different from the air pressure in closed container 13, so as to form a pneumatic flow in closed container 13
.
The present invention is also mounted with closed container 13 in axial flow blower 12, the guarantee of work closed container 13 of axial flow blower 12
The uniformity of gas componant.
To make the control of valve sensitiveer, described valve selects magnetic valve 3.
To make the control of regulating valve more accurate, described regulating valve selects electric control valve 4.
Strengthen the process control of the entrance closed container 13 of new gas source, described new gas source and gas distributor 6 it
Between be mounted with stop valve 5.
Silencer 7 has been installed additional to reduce in noise, described new gas source return path.
Surge tank 8 is mounted between check-valves 10 and the gas outlet of closed container 13, for stablizing gas in closed container 13
Simultaneously reduce the impact produced when gas is directly extracted out to vacuum equipment in body flow field.
To make the connection of gas flow field device simpler and reducing the noise produced during equipment use to pass through gas
In the incoming closed container 13 of conduit gas conduit, flexible joint is mounted between check-valves 10 and the gas outlet of closed container 13
9。
Described new gas source can be ozone, can to ensure the quality for the air being filled with closed container 13
To select new wind filter 1 again, filtered air is under the license of valve, into adjustable valve.
In order to more intuitively observe the gas flow into closed container 13 and facilitate the regulation and control of electric control valve 4 to enter close
The size of gas flow in container 13 is closed, orifice flowmeter 2 is mounted between new gas source and valve.
Protection scope of the present invention is not limited only to the technical scheme disclosed in specific embodiment part, and all make use of is taken out
Go out old air, be filled with quality controllable new source of the gas, so as to fall in the technical scheme that closed container is internally formed gas flow
Enter protection scope of the present invention.
