Abstract

Изобретение относитс к сельскому хоз йству и может быть использовано дл подачи воды в дождевальные машины и установки. Цель изобретени - повышение надежности работы. Устройство дл подачи воды в дождевальные машины и уг.тановки состоит из водоприемной муфты 1 и установленном на трубопроводе 5 с перфорированным участком ползунковой муфты 6. Ползункоеа муфта 6 имеет две камеры 7 и 9. На ползумковой муфте 6 установлена водоприемна муфтэ 1, сообщенна с камерой 9. Камера 9 гидравлически св зана через золотниковый переключатель с гидроприводом . Ползуикоса муфта кинематически св зана с гидроприводом и сигнальной вешкой 24, и подпружинена относительно трубопровода . Гидррпризод гидравлически св зан с сигнальным звуковым блоком, выполненным в виде газоструйного эжектора. При работе ползункова муфта 6 автоматически поддерживает необходимый напор дл дождевальной машины и установки, что nor.u- шает надежность работы. 2 з. п. ф-лы, 4 ил. (ЛThe invention relates to agriculture and can be used to supply water to sprinklers and plants. The purpose of the invention is to increase the reliability of work. The device for supplying water to the sprinkling machines and the angle of assembly consists of a water inlet coupling 1 and installed on the pipeline 5 with a perforated section of the slide coupling 6. The slide coupling 6 has two chambers 7 and 9. On the slide coupling 6 there is a water receiving coupling 1 connected to the chamber 9. Chamber 9 is hydraulically connected through a hydraulic slide valve. The polyzicos coupling is kinematically connected to the hydraulic actuator and the signal pole 24, and is spring-loaded relative to the pipeline. The hydraulics unit is hydraulically connected with a signal sound unit made in the form of a gas-jet ejector. During operation, the slide coupling 6 automatically maintains the necessary head for the sprinkler and the installation, which ensures reliable operation. 2 h. the item of f-ly, 4 ill. (L
