Technical background
According to the mode that produces pressure, pressure unit can be divided into waterpower squeezing unit (hydraulic pressure installation), mechanical presses device and explosion squeezing unit etc., but squeezing unit mainly relies on outside resources to produce pressure now; Waterpower squeezing unit and mechanical presses device need configure huge external system in work chamber, have strengthened its difficulty (for example extremely low temperature in the cryogenic freezing case) of automatically using at confined space; Although the explosion squeezing unit can produce pressure in limited space, working lipe is short.Visible, above-mentioned squeezing unit is the internal pressure produced while utilizing water freezing in the confined space not yet in effect all.
The model utility content
The technical problems to be solved in the utility model is: the problem of the internal pressure that general squeezing unit produces in the time of can not effectively utilizing water freezing in the confined space.For addressing this problem, the utility model provides a kind of squeezing unit of the internal pressure that phase transformation produces while simply utilizing water freezing in the confined space, the internal pressure work of phase transformation generation when this device only utilizes water freezing in confined space.
The technical solution adopted in the utility model is, a kind of squeezing unit of the internal pressure that phase transformation produces while utilizing water freezing, by the work chamber with demountable structure and gas holder, formed, elastic diaphragm is set in work chamber, work chamber is divided into for the working space of splendid attire working medium with for the confined space of the incompressible antifreeze liquid of splendid attire; Elastic diaphragm is set in gas holder, by gas holder be divided into for the confined space of the incompressible antifreeze liquid of splendid attire and splendid attire compressible gas confined space; The confined space for the incompressible antifreeze liquid of splendid attire of work chamber is connected with the confined space for the incompressible antifreeze liquid of splendid attire of gas holder by the descending connecting tube that descending pressure control switch is housed and the up connecting tube that up pressure control switch is housed.
Concrete technological scheme is as follows:
A kind of squeezing unit of the internal pressure that phase transformation produces while utilizing water freezing, be comprised of airtight work chamber 1 and the gas holder 10 of screwed demountable structure 4; Described screwed demountable structure 4 is by threaded closure plug 3 sealings; In described airtight work chamber 1, elastic diaphragm 5 is set, airtight work chamber 1 is divided into for the working space 2 of splendid attire working medium water with for the first confined space 6 of the incompressible antifreeze liquid of splendid attire; Lower elastic diaphragm 13 is set in described gas holder 10, gas holder 10 is divided into for the second confined space 11 of the incompressible antifreeze liquid of splendid attire with for the confined gas space 12 of splendid attire compressible gas; Described the first confined space 6 is connected with the second confined space 11 by the descending connecting tube 9 that descending pressure control switch 8 is housed and the up connecting tube 14 that up pressure control switch 15 is housed respectively.
Described descending pressure control switch 8 is connected with descending pressure meter 7 by sense cell, and described up pressure control switch 15 is connected with up pressure meter 16 by sense cell.
Described screwed demountable structure 4 is 1 or 3.
The internal pressure that when squeezing unit of the present utility model can freeze water under natural climate or artificial condition, phase transformation produces changes isotropic pressure into.Its working principle is,
When external temperature during lower than 0 ℃, descending pressure control switch 8 and up pressure control switch 15 are closed, working medium generation water in working space 2-ice phase transformation, volume increases approximately 8%, the internal pressure increased thus will be opposite to object in working medium (analogy be positioned over pressure changing the piezoelectric constant that can produce potential difference in working medium water) and produce isotropic pressure, simultaneously, the internal pressure increased is passed to the incompressible antifreeze liquid in the first confined space 6 by upper elastic diaphragm 5, when the pressure of working space 2 and the first confined space 6 reaches setting value, descending pressure control switch 8 is opened, incompressible antifreeze liquid in the first confined space 6 enters the second confined space 11 in gas holder 10 by descending connecting tube 9, entering of the second confined space 11 interior incompressible antifreeze liquid diminishes 12 space, confined gas space, and the pressure of the compressible gas in confined gas space 12 increases, and the pressure of gas holder 10 interior all confined spaces becomes large.Under the effect of extraneous thermal source, working medium in working space 2 finishes water-ice phase transition process, volume no longer enlarges, pressure increase process finishes, start ice-water and become process, the volume of working space 2 reduces and reduces with the working medium volume, the pressure of first confined space 6 at incompressible antifreeze liquid place reduces, when the pressure difference of the first confined space 6 and the second confined space 11 is reduced to setting value when following, descending pressure control switch 8 on descending connecting tube 9 is closed, and up pressure control switch 15 is opened; Under the pressure-acting of the compressible gas in confined gas space 12, the incompressible antifreeze liquid in the second confined space 11 enters the first confined space 6 by up connecting tube 14.After ice-water becomes end, squeezing unit is got back to reset condition; This squeezing unit is placed in to the environment lower than 0 ℃ again, and this squeezing unit reenters the process that produces pressure.
The internal pressure that when squeezing unit of the present utility model can freeze water under natural climate or artificial condition, phase transformation produces changes isotropic pressure into.If install turbine additional in descending connecting tube 9 and up connecting tube 14, driven rotary when incompressible antifreeze liquid descending and up, the internal pressure that the utility model water-ice phase transformation and ice-water sell of one's property is given birth to is converted into the available energy; Or place piezoelectric constant in working space 2, the internal pressure that can make the utility model water-ice phase transformation and ice-water sell of one's property give birth to is converted into can utilize electric energy.
