Description
The present invention relates to the vacuum technique field, it discloses and has a kind ofly obtained vacuum, keeps the vacuum system of vacuum by fluid tightness by liquid gravity.
" any one vacuum system always has a container to be found time, one to obtain the equipment (vacuum pump) of vacuum and the pipeline that connects them; To add valve in addition, measure measurer (vacuum gauge) and other accessorys of vacuum " (selecting from Central China one chief editor's " vacuum experiment technology " the 29th page; Shanghai science tech publishing house July in 1986 the 1st edition), this is that world today's vacuum circle is generally acknowledged.Liquid gravity vacuum system does not need " equipment (vacuum pump) that obtains vacuum ", and no vacuum special device is the essential characteristic of liquid gravity vacuum system.
With reference to Fig. 1, with water is example, now its structure and principle is described below.
Liquid gravity vacuum system mainly is made of the pipeline of vacuum vessel, bottom valve K1, water inlet (liquid) valve K2, vent valve K3, vacuum gauge B, lower end band U type water (liquid) envelope, if need, can set up degree of vacuum modulating valve K4.Special procure and ask H to be equal to or greater than 10.5 meters (to other liquid; H can change according to its proportion adjust).See Fig. 1 (a).
Working principle: close bottom valve K1, open vent valve K3, open inlet valve K2 again, along with water enters vacuum vessel, air is discharged by K3, all be full of water up to vacuum vessel (comprising water pipe), close K3, close K2 again, open bottom valve K1 then, water is owing to the discharge of the U-shaped mouth of pipe is passed through in action of gravity, and is last, and the water surface in the pipe rests on (h numerical value is relevant with on-the-spot altitude with liquid specific gravity) on the h height.At this moment, be ultrahigh vacuum (on the macroscopic view, can think that it is an absolute vacuum) in the vacuum vessel, it produces by liquid gravity, keeps by fluid tightness.Open K3 again, can eliminate vacuum, make system get back to original state.See Fig. 1 (b).If K1, K2, K3 all are solenoid valves, above-mentioned whole operation process can realize electronic program chemical control system.
Observe vacuum gauge B, regulate K4, can obtain high vacuum, rough vacuum and coarse vacuum.See Fig. 1 (c).B and K4 can form electronic-controlled system.
Compare with all kinds of vacuum systems of present use, liquid gravity vacuum system has four outstanding advantages.
(1) simple and easy to do, use value is big.
(2) do not need existing vacuum special device.
(3) do not consume or consume seldom energy, just can obtain vacuum and the long-term vacuum state that keeps quickly.
(4) the vacuum capacity can design according to actual needs, does not have technical difficulty.
These four advantages show that the existing relatively all kinds of vacuum systems of liquid gravity vacuum system have revolutionary progress on Technological Economy.It will make and be mainly that microcosmos is explored and for the vacuum technique of special manufacturing process service steps into macrocosm, be that the field is served widely, thereby bring global economic benefit and social benefit.
Follow the liquid gravity vacuum system notion, can derive series of related concepts, as on-liquid Operation System of liquid vacuum article bunker (cabinet, case), liquid vacuum Pesticidal and sterilizing chamber, liquid vacuum rubbish sterilization treatment device, liquid vacuum organic sewage processor, liquid vacuum Operation System, liquid vacuum or the like.
(1) main cause one that rots of food is because oxidation, the 2nd, because microbial attack, therefore, secluding air (oxygen) and kill microorganisms or to weaken its vitality be the main path that food fresh-keeping is stored.Freezing secluding air and low temperature can make a large amount of microbial deaths or weaken its vitality owing to can generate ice on the food top layer, thereby it is the main means of the present storage of food fresh-keeping in the world.Freezing storehouse, refrigerator-freezer, refrigerator are exactly the hardware of these means.
Freezing technology has produced great potential hazard to ball ecological environment when bringing convenience to the human lives: fluorine Lyons has begun to injure existent environment of people to the destruction of atmospheric ozone layer.The liquid vacuum article bunker (cabinet, case) that is derived from by liquid gravity vacuum system provides feasible approach for solving this global difficult problem.
Itself does not almost have air " vacuum ", and all animals, microorganism, bacterium can't survive down at vacuum state (low pressure, anaerobic), and therefore, vacuum environment can satisfy the requirement of food fresh-keeping storage.Replace the effective scheme that freezing storehouse, refrigerator-freezer, refrigerator are the protection atmospheric ozone layers respectively with liquid vacuum article bunker, cabinet, case.See Fig. 2 (a).
(2) to some strategic stockpile, available liquid vacuum article bunker is realized long-term vacuum storage.See Fig. 2 (a).
(3) some is needed the article that sterilization handles (as medical equipment etc.), handle in large quantity available liquid vacuum Pesticidal and sterilizing chamber.See Fig. 2 (a).
(4) liquid vacuum rubbish sterilization treatment device can be used to sterilization treatment rubbish in large quantity.See Fig. 2 (a).
(5) liquid vacuum organic sewage processor can be handled organic sewage in large quantity by vacuum sterilization.See Fig. 2 (b).
(6) the liquid vacuum Operation System can satisfy under vacuum state the needs of article being processed (as packing etc.).Its principle is that motor is placed outside the vacuum chamber, and transmission shaft passes liquid power is reached special-purpose operated implement in the vacuum chamber.See Fig. 3.
(7) some technical matters does not allow liquid to soak vacuum vessel and article, and the on-liquid Operation System of liquid vacuum can satisfy this requirement.This system's cardinal principle is to set up an on-liquid vacuum operation chamber by liquid seal.See Fig. 4.In order to improve the degree of vacuum of on-liquid vacuum operation chamber, can consider several liquid gravity vacuum systems in parallel or allow single liquid gravity vacuum system periodic duty repeatedly constantly (whenever once circulate, K5 will finish once and close, close action).
According to above-mentioned introduction, can inference: the generation of liquid gravity vacuum system, will break existing vacuum technique general layout, transform existing vacuum industry system, and storage industry, sterilization purification industry etc. are produced strong impacts.Along with its enforcement, popularization and further exploitation, liquid gravity vacuum system will be penetrated into the All aspects of of human society production and life.
Claims (2)
1, a kind of vacuum system, not needing it is characterized in that existing vacuum special device (vacuum pump), pipeline, vacuum gauge B and liquid by vacuum vessel, bottom valve K1, water inlet (liquid) valve K2, vent valve K3, band U type water (liquid) envelope constitute (if being necessary to set up degree of vacuum modulating valve K4), it produces vacuum by liquid gravity, and the sealing by liquid keeps vacuum.
