The invention relates to a micro-moistening pipe and a micro-moistening irrigation system. The traditional agricultural irrigation methods, such as water irrigation, canal irrigation and the like, are coarse and low in efficiency, and the utilization rate of water is about 10%, therefore, the waste of water resources is astonishing, and a series of problems, such as soil salinization and the like, are easy to cause. For overcoming the disadvantages existing in the traditional irrigation, the irrigation methods, such as sprinkling irrigation, trickle irrigation and the like, are spread and applied at home and abroad, but when these irrigation methods are used, the utilization rate of water is only about 50%, and about half of irrigation water is still wasted. The micro-moistening pipe comprises a hose with a double-layer structure, and the hose is composed of an inner pipe (1), and an outer pipe (2) of a permeable protective sleeve, wherein the wall of the inner pipe is provided with micro through holes (3), and the diameter of the micro through hole is 10-900 nm. The micro-moistening pipe and the micro-moistening irrigation system provided by the invention are used for water-saving agricultural irrigation and water-saving reclamation on saline-alkali lands.

The invention provides a semi-closed type timing constant-volume thermodynamic circulation method and a semi-closed type timing constant-volume thermodynamic circulation system of a prime motor. The thermodynamic circulation method comprises six processes, namely multi-compression-stage intercooling, countercurrent heat exchanging, timing constant-volume burning, adiabatic expansion, aftercooling, and carbon dioxide and water removal. Heat-power conversion is achieved in the thermodynamic circulation. In the process of multi-compression-stage intercooling, compression power consumption is lowered; in the process of countercurrent heat exchanging, the enthalpy of an expanded working medium is recovered to participate in thermodynamic circulation; the process of timing constant-volume burning effectively inhibits the generation of harmful pollutants such as HC, CO, PM and NOx; in the process of adiabatic expansion, complete expansion for working is achieved; in the process of aftercooling, the working medium is further cooled to the environment temperature and the expansion ratio in the process of adiabatic expansion is enhanced; in the process of carbon dioxide and water removal, the carbon dioxide and the water generated in the process of timing constant-volume burning are removed; the remaining work mediums participate in the next thermodynamic circulation. By the method and the system, the direction is defined for designing a high-efficiency low-pollutant-emission and high-performance prime motor in the future.

A control valve in the second chamber controls discharge of fluid from the second chamber. A flow state-sensing device introduces fluid in the fluid pipe to the second chamber when the fluid pipe ruptures and leaks.
