A Different Kind of scientific terms, but literally, spread through the soil to the ground water is used for crop production. Although only 15 percent of the world's agricultural lands are irrigated and non-irrigated rainfed and the rest 85% are used in agriculture and food production, but half of the world's irrigated land is obtained. This indicates the importance of the role of irrigation in the agricultural sector.
In general, monte moir the pressure of modern irrigation and drip irrigation and sprinkler are two general ways. Sprinkler irrigation and drip irrigation efficiency of 70 percent to 95 percent, to 20 percent of the sprinkler system monte moir and drip irrigation systems waste water to 5%, whereas surface irrigation methods are costly, even with air- irrigation efficiency does not exceed 50% of the land in the traditional lands of our country so that most of them are watered even less than 35 per cent. This means that if the sprinkler and drip irrigation methods do not use 65% of water is lost from the farms and waste water, including the transmission channel, monte moir 75 percent of mortalities exceed. Therefore, the use of pressurized irrigation systems, water losses can be avoided to economic growth and sustainable development monte moir in all fields monte moir followed to achieve.
The gated pipe irrigation ditch or surface water flows and the gradual penetration of plant roots are in the soil. Surface

irrigation, basin irrigation in three ways - irrigation and furrow irrigation monte moir tape is played.
Surface irrigation methods due to the low initial investment, low maintenance costs and requires less energy than pressure irrigation methods, irrigation methods, one of the most popular in the world. Due to the inherent nature of the soil and water relationships, irrigation management complexity and lower efficiency of the major weaknesses of this method is that due to the low degree of automation, the impossibility

of using tools and equipment to measure and control the flow and the other labor force is skilled in irrigation. Recent advances in the technology of surface irrigation methods significantly reduce the efficiency of the system under pressure or in terms of destroyed.
Due to problems in the earth to water the fields, streams, there are calls to other methods that can be used for this purpose can also be evaluated to preserve Irrigative benefits superficial disadvantages equivalents will.
Use pipe valve that eliminates some of the drawbacks monte moir of such techniques is surface water. In this way, water, soft polyethylene tube with an adjustable valve replacement in the field of terrestrial streams (up to 4 channels) will be. The results of the evaluation conducted in various countries including Australia, China, Egypt and Iran shows that the application of the methods of irrigation pipe valve to reduce the water level of 28-25%, and increase the efficiency of water use by about 30 percent The traditional methods are. Another benefit monte moir of this approach can be utilized to manage and simple, monte moir easy leaching, save 5 percent of the agricultural land, more uniform distribution of water, save energy without affecting the quality of water in crop yields and take advantage (in terms of the physical and Chemical) in water without damaging the system monte moir (unlike drip irrigation systems) can be mentioned.
Azlvlh use of surface water, especially water line valve to improve the world Azdhh 1960 was introduced. Primary tubes are made of aluminum, but with the development of the petrochemical monte moir industry and the production monte moir of PVC plastic, this material is gradually replaced by aluminum systems profitable, monte moir efficient style created an atmosphere monte moir that was capable of replacing the traditional system of common Vkanal Surface irrigation is.
Pipe valve consists of a soft polyethylene pipes with adjustable valves as Class 4 channels can be a good alternative to terrestrial channels. In this system, instead of the water flowing in a pipe and the creek embankment seepage losses will be minimal on the terrestrial channels. The tubes in the 100 and 200 meter coils are made by special clamps or connected to the outlet basin and along the length of the piece is based irrigation to the proper length. Periodically with water outlet pipe openings (vents), and at the opening of each valve is adjustable by a special cap. As the output current of each gate can be tailored to the required amount with the required amount (max 5/2 liters per second) can be adjusted.
Results and discussion presented in this paper revealed that the tube valve core tool to improve surface irrigation system is considered. Valve-tube design with precise leveling, a uniform water distribution and irrigation water to improve the land for farming and gardening. While the product as compared to traditional surface irrigation methods dramatically increases. In other words, in contrast to traditional surface irrigation methods, systems
