Description

The phase transformation acting device of high pressure mixing dielectric gas

Technical field

The utility model relates to a kind of acting device of dielectric gas, relates in particular to the acting device that a kind of high pressure mixing dielectric gas undergoes phase transition by acting.

Background technique

Using in gas medium circular work system, be that gas is done volumetric work, and the volumetric work of gas maximum is the phase transformation acting of gas, and existing gas circulation working system is as Rankine cycle, the dielectric gas that all can not make to do work such as Carnot's cycle undergoes phase transition by acting, want to make gas to undergo phase transition and all must consume external work to gas compression or reduce temperature, patent of invention " across critical low-temperature air energy generating device " as application number 201110279848.9, adopted equally compressor to compress and make its liquefaction dielectric gas, hot merit low conversion rate so not only, and need consume a large amount of external works, also need two thermals source of height simultaneously.

The model utility content

In order to overcome the deficiency that in existing gas medium circular work system, dielectric gas can not undergo phase transition by the acting direct liquefaction, the utility model provides a kind of phase transformation acting device of high pressure mixing dielectric gas, this device can make the dielectric gas direct liquefaction and undergo phase transition in expansion acting process, export maximum volumetric work, and can automatically produce the working state that a low-temperature heat source maintains working system.

The utility model is to address the above problem adopted technological scheme to be: a kind of phase transformation acting device of high pressure mixing dielectric gas, comprise that high pressure mixing dielectric gas, acting cylinder, low-temp low-pressure gas-liquid mixed media gas, air inlet electromagnetic valve, exhaust solenoid valve, connecting pipeline form, wherein the high pressure mixing dielectric gas is connected with the acting cylinder by air inlet electromagnetic valve, and the acting cylinder is connected with low-temp low-pressure gas-liquid mixed media gas by exhaust solenoid valve.

Said mixed medium gas is the low boiling point working medium gas of the different critical temperature of being mixed by a certain percentage by two or more.

The phase transformation acting device of high pressure mixing dielectric gas mainly comprises acting cylinder or decompressor, high pressure mixing dielectric gas, solenoid valve and connecting pipeline.The piston of acting cylinder from left to right or from right to left moves once, and the high pressure mixing dielectric gas is double acting in cylinder.The high pressure mixing dielectric gas is the low boiling mixed medium gas composition by two or more different critical temperature, acting first will make while starting the to do work delivery outlet of cylinder is manufactured an environment under low pressure, the entrance of acting cylinder is by the displacement distance of the piston of electromagnetic valve acting cylinder, export a certain amount of shaft work, then air inlet electromagnetic valve is closed, exhaust solenoid valve keeps conducting, piston continues to move and make dielectric gas do the adiabatic expansion acting by original direction, owing to being low boiling mixed medium gas, and mix by a certain percentage, in adiabatic expansion acting process, the slightly high dielectric gas of critical temperature starts liquefaction, make mixed medium gas become gas liquid mixture, carrying out along with adiabatic expansion acting process, the temperature of gas-liquid mixed media gas is dropped to and approach liquefaction point, piston movement completes an acting process during to terminal, so shield is controlled the solenoid valve upset and is made to do work cylinder while oppositely doing work, the dielectric gas of the gas-liquid mixed of this low-temp low-pressure is discharged, so reciprocal acting output shaft work.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described further

Fig. 1 is the workflow schematic diagram of one of the utility model preferred embodiment.

Embodiment

As shown in Figure 1 in embodiment, a kind of phase transformation acting device of high pressure mixing dielectric gas, comprise that high pressure mixing dielectric gas 1, acting cylinder 2, low-temp low-pressure gas-liquid mixed media gas 3, air inlet electromagnetic valve 4,5, exhaust solenoid valve 6,7, connecting pipeline form, wherein high pressure mixing dielectric gas 1 is connected with acting cylinder 2 by air inlet electromagnetic valve 4,5, and acting cylinder 2 is connected with low-temp low-pressure gas-liquid mixed media gas 3 by exhaust solenoid valve 6,7.

Said mixed medium gas is the low boiling point working medium gas of the different critical temperature of being mixed by a certain percentage by two or more.In other words, 1 is the pressurized gas end, and 2 is the acting cylinder, and 3 is the low-temp low-pressure end, and 4,5,6,7 is solenoid valve, the position of piston in the acting process that k1, k2, k3, k4 are the acting cylinder,

When acting starts, solenoid valve 4, 7 open, 5, 6 cut-offs, piston moves to k2 from k1, dielectric gas constantly enters cylinder and promotes the piston acting, piston is solenoid valve 4 cut-offs during to k2, solenoid valve 7 continues conducting, gas starts to do the adiabatic expansion acting, temperature and pressure starts to descend, piston is from k2 to k3, in mixed medium gas, the slightly high dielectric gas of critical temperature completes liquefaction, the piston dielectric gas slightly low to the k4 critical temperature from k3 continues further to drop to minimum by do work make the to do work temperature and pressure of the gas-liquid mixed media gas in cylinder of adiabatic expansion, solenoid valve 7 cut-offs, now complete an acting process, enter next acting process during the piston reverses direction motion, solenoid valve 5, 6 conductings, 4, 7 cut-offs, so repeatedly carry out.
