Изобретение относитс к сельскому хоз йству, а именно к поливной техникеThis invention relates to agriculture, in particular to irrigation technology.

Известен водовыпуск к поливньлм трубопроводам, включающий конический запорный орган, установленный в отверстии трубопровода и закрепленный на упругом элементе l .A water outlet to watering pipelines is known, which includes a conical shut-off element mounted in the pipe hole and fixed on the elastic element l.

Однако при настройке такого водовыпуска на требуемый расход необходимо примен ть ручной труд.However, when setting up such a discharge to the required flow rate, manual labor is necessary.

Наиболее близким к изобретению по технической сущности вл етс водовыпуск, включающий корпус и ус:тановленный в нем конический запорный орган с приводсил в виде упругого элемента р The closest to the invention to the technical essence is a water outlet, comprising a body and a mustache: a conical locking body mounted in it with a lead in the form of an elastic element p

При изгибе корпуса надежность работы этого водовыпуска снижаетс , что вли ет на его регулировочные функции.When the case is bent, the reliability of this outlet is reduced, which affects its adjustment functions.

Цель изобретени - повышение точности регулировани расхода по длине трубопровода. Это достигаетс тем, что упругий элемент заключен в камеру, котора расположена в кор пусе, с образованием в ней двух полостей, сообщенных соответственно с трубопроводом и со сливом. The purpose of the invention is to improve the accuracy of controlling the flow along the length of the pipeline. This is achieved by the fact that the elastic element is enclosed in a chamber, which is located in the housing, with the formation in it of two cavities communicated respectively with the pipeline and with the drain.

Claims

The outlet has a housing 1 with a chamber 2. It also contains a conical locking member 3 with an elastic element 4 and a plug 5. When assembling the water outlet between the housing, the stopper and the elastic member of the locking member form a cavity that communicates through the opening 6 in the housing with the cavity of the pipeline 7. The chamber 2 on the one hand together with the housing Forms a drain opening 8, which through the opening 9 of the housing communicates with the pipeline cavity, and on the other hand together with the housing and the elastic element - a cavity connected to the drain opening 8 through from ERSTU ... 10 in the housing inner wall of the housing has an overflow groove 11 for fixing the elastic member of the valve plug retaining ring 12. The housing is secured to the wall of the pipe 13 at its aomaturu openings. When the elastic element 4 of the closure member is in position, one constant flow is eliminated on each groove. To change the size of the irrigation spray, remove the plug 5 from the housing by pressing the antennae of the locking ring 12, pull the element 4 out of the groove and insert it into another groove, while adjusting the appropriate size of the irrigation drift. The outlet works as follows. Water transported through pipe 7 through opening 9 of housing 1 enters drain outlet 8 with an expanded outlet part (horizontal part of the opening) to quench the kinetic energy of the irrigation stream and then into the irrigation furrow. At the same time, water flows through the opening 6 of the housing into the cavity above the elastic element, where a pressure occurs, equal to the piezometric pressure in the pipeline. As a result, the valve body begins to move in the opposite direction to the flow of the irrigation jet, stretching the elastic element 4, changing (reducing) the life-time of hole 9 and maintaining a constant flow rate. With a decrease in pressure in the pipeline 7, the elastic element 4, moving in the opposite direction, increases the living section of the hole 9, while also maintaining a constant flow rate. If it is necessary to disconnect some areas from irrigation, the drain hole is closed with a stopper. At the end of the irrigation season, the water outlet can be removed from the pipeline with little effort. A water outlet to irrigation pipelines provides a constant flow in a large range of pressure in the pipeline, its shut-off member works reliably in the entire pressure drop zone in the pipeline, Invention Flow outlet to the irrigation tubing, including a conical shut-off member with an elastic drive element, characterized in that, in order to increase the control accuracy, the elastic element is enclosed in a chamber, which is located in the housing, with the formation of two cavities in it, nnyh trubsotrovodom respectively with and with a drain.
