Abstract
The invention discloses a gas flow field device and relates to a mechanical device. The gas flow field device comprises a novel gas source, a valve, a regulating valve, a gas distributor, a check valve and a vacuum pump. Due to the mode of exhausting the old gas with the vacuum pump and filling the novel gas source, the gas forms a gas pressure cyclone in a closed container. Due to the existence of the gas pressure cyclone, the gas forms a flow gas field in the closed container, so that uniformity of gas in the closed container is realized, the old gas is exhausted, the quality of the novel filled gas is controllable, the quality of gas in the closed container is guaranteed, and the gas in the closed container is uniform. Therefore, the working efficiency and implementation quality in scientific or medical experiment can be greatly improved.
Description
Technical field
The present invention relates to a kind of mechanical device, be specifically related to the gas flow field device under a kind of closed environment.
Background technology
Along with the development of science, the closed environment in other words experiment in the closed container is more and more.More and more stricter to the environmental requirement in the closed container, more common is exactly the development and application of hyperbaric oxygen chamber.At present, all be directly to be filled with gas in the container or to adopt airtightly in closed container, to provide gas by breathing mask in that gas is provided in pressure vessel.For example in hyperbaric oxygen chamber, the use oxygen mask can guarantee the normal existence of personnel in the container, but other can not use the biology of breathing mask to survive.Such as the gas of directly annotating in the container, can not control accurately, and the gaseous mass in the container and uniformity coefficient are not guaranteed.Above-mentioned technical problem has been limited to the scope of application of container, and a lot of medical experiments can't be finished or be difficult to and finish, and plenum system of the prior art is unfavorable for the progress of the science that the closed container experiment is relevant and the development of medical science.
Summary of the invention
For solving the technical problem that the gaseous mass in the closed container and uniformity coefficient can't guarantee in the prior art, the invention provides a kind of gas flow field device, the gas flow field be can in closed container, form, thereby gaseous mass and uniformity coefficient in the closed container guaranteed.
The gas flow field device, comprise new gas source, valve, control valve, gas distributor, check-valves, vavuum pump, it is characterized in that, controllable valve is installed on the described new gas source, be used for control gas and carry or stop the conversion of feed status, new gas source out enters control valve afterwards from valve, flow velocity and total amount by control valve control inputs gas, gas enters gas distributor after by control valve, gas distributor is fixedly mounted on the top of closed container, is used for distributing the gas flow that enters the closed container diverse location; The gas outlet of closed container links to each other with check-valves by gas conduit, and the other end of check-valves links to each other with vavuum pump, and interconnecting in the device all is by gas conduit, and the each several part of device is coupled together.
The present invention is by extracting old gas out, be filled with the mode of new source of the gas, making gas form an air pressure in closed container revolves, because of the existence that air pressure revolves, make gas in closed container, form flow gas field, thereby realize that gas in closed vessel is even, and old gas is drawn out of, the new gaseous mass that is filled with is controlled, has both guaranteed the gaseous mass in the closed container, also makes simultaneously the gas uniform in the closed container.Can greatly improve operating efficiency and implementation quality in science or the medical experiment.

The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described further:
The gas flow field device, comprise new gas source, valve, control valve, gas distributor 6, check-valves 10, vavuum pump 11, it is characterized in that, controllable valve is installed on the described new gas source, be used for control gas and carry or stop the conversion of feed status, new gas source out enters control valve afterwards from valve, flow velocity and total amount by control valve control inputs gas, gas enters gas distributor 6 after by control valve, gas distributor 6 is fixedly mounted on the top of closed container 13, is used for distributing the gas flow that enters closed container 13 diverse locations; The gas outlet of closed container 13 links to each other with check-valves 10 by gas conduit, and the other end of check-valves 10 links to each other with vavuum pump 11, and linking to each other in the device all is by gas conduit, and the each several part of device is coupled together.In use, open vavuum pump 11, then by check-valves 10 and gas conduit the old air in the closed container 13 that is attached thereto is extracted out and discharging; In vavuum pump 11 work, Open valve, make the gas in the new source of the gas enter control valve, adjust gas flow rate by control valve, new gas enters gas distributor 6 and enters in the closed container 13 by reallocation, because of the air pressure in the gas distributor 6 different from the air pressure in the closed container 13, thereby in closed container 13, form an air pressure flow field.
The present invention is also in the closed container 13 interior axial flow blowers 12 of having installed, the uniformity of axial flow blower 12 guarantee of work closed containers 13 composition of gases within.
Sensitiveer for the control that makes valve, described valve is selected magnetic valve 3.
More accurate for the control that makes control valve, described control valve is selected electric control valve 4.
Strengthen the process control that enters closed container 13 of new gas source, between described new gas source and the gas distributor 6 stop valve 5 has been installed.
For reducing noise, installed silencer 7 additional in the described new gas source return path.
Between check-valves 10 and closed container 13 gas outlets, surge tank 8 has been installed, the impact that when being used for stabilize containment container 13 gas flowfields and reducing gas directly extracting out vacuum equipment is produced.
Simpler and reduce the noise that produces in the equipment use procedure and import in the closed container 13 by the gas conduit gas conduit for the connection that makes the gas flow field device, between check-valves 10 and closed container 13 gas outlets, flexible joint 9 has been installed.
Described new gas source can be ozone, for guaranteeing to be filled with the quality of the air in the closed container 13, can select new wind filter 1 again, and filtered air enters adjustable valve under the license of valve.
In order to observe more intuitively the size that enters the gas flow in the closed container 13 and make things convenient for electric control valve 4 regulation and control to enter gas flow in the closed container 13, between new gas source and valve, orifice flowmeter 2 has been installed.
Protection scope of the present invention is not limited only to the disclosed technical scheme of specific embodiments part; all utilization extracted old air out; be filled with quality controllable new source of the gas, thereby all fall into protection scope of the present invention in the inner technical scheme that forms the gas flow field of closed container.
