При повышении уровн  в колодце 12 возрастает пьезометрический напор в дренах-увлал нител х 13, что приводит к повышению уровн  грунтовых вод.

The water from the inlet pipe enters the receiving well 12 and the damper humidifiers 13. As the level in the well 12 rises, the piezometric pressure in the drains drains out. 13, which leads to an increase in groundwater levels. Due to the presence of a float chamber 8 s, and a float; ch11m valve 7, which is hydraulically connected to the electromagnetic claian 4 and the locking organ and is a pressure regulator, limiting the flow in the drains of the drain by means of maintaining a given level in the well 12 and water from the groundwater flow from it. The level in the well is set by moving the camera around 8 vertically. When the groundwater reaches a predetermined level, this level will be maintained, but it will be wet, the soil will not reach the target level due to water, | Rno14) podnizizami.

fS И будет закрыт, пока влажность спова не снизитс . Благодар  наличию дождемера 3 устройство реагирует па осадки и прекращает подачу воды при их выпадении в достаточном количестве. Применение предлагаемого устройства позволит повысить точность регулировани  и поддерживать правильный баланс влажности в почве. изобретени  Ф о р м у ,1 а Устройстио дл  регулировани  влажности ночвы нри полночвенном орошении, включаюн ,ее установленный на подвод щем трубопроводе запорный орган, св занный через электромагнитный клапан с датчиком влажности, и регул тор наиора, отличающеес  тем, 410, с целью исключени  переувлажнени  почвы нри капилл рном подпитывании после прекращени  подачи воды в оросительную сеть, регул тор напора выпо.тпен в виде поплавковой камеры, гидравлически св занной с электромагнитным кл; паном и запорным органом до и после него.fS And it will be closed until the humidity of spov decreases. Due to the presence of a rain gauge 3, the device reacts to precipitation and stops the flow of water when they fall out in sufficient quantities. The application of the proposed device will improve the accuracy of regulation and maintain the correct moisture balance in the soil. Inventions Phromy, 1a A device for controlling the humidity of a night in a full-flow irrigation, including its shut-off element mounted on the supply pipe, connected through a solenoid valve with a humidity sensor, and a controller, 410, with the aim of elimination of soil overmoistening with capillary feeding after stopping the supply of water to the irrigation network, the pressure regulator is in the form of a float chamber hydraulically connected to the electromagnetic valve; pan and locking body before and after.
