Abstract
Изобретение м.б. использовано в несамовсасывающихс центробежных насосах , наход щихс над уровнем жидкости . Цель изобретени - повьшение надежности насоса с устр-вом дл автоматической заливки путем повышени быстродействи срабатывани отсечного клапана. Корпус (К) 1 снабжен всасывающим и нагнетательным трубопроводами . Вакуумпровод 4 подключен к полости (II) К 1 и источнику низкого давлени . Отсечной клапан установлен на вакуумпроводе 4 и включает кожух 7, разделенньй упругой перегородкой 8 на две половины 9, 10. Половина 9 сообщена с Ц К 1,. половина 10 - с атмосферой. Запорный и нажимной элементы 11, 12 св заны с перегородкой 8. В К 1 ниже его верхней точки выполнено отверстие 13, поперечное сечение равно поперечному сечению кожуха 7. Кожух 7 соединен с К 1 по периметру, отверсти 13. Перегородка 8 м.б. выполнена или из эластичного материала, или из гофрированной резины. 1 з.п. ф-лы, 2 ил. ю (ЛInvention m. used in non-self-priming centrifugal pumps located above the liquid level. The purpose of the invention is to increase the reliability of the pump with a device for automatic priming by increasing the response time of the shut-off valve. The housing (K) 1 is equipped with suction and discharge piping. The vacuum line 4 is connected to the cavity (II) To 1 and a low pressure source. The shut-off valve is installed on the vacuum pipe 4 and includes a casing 7, divided by an elastic partition 8 into two halves 9, 10. Half 9 communicates with C K 1 ,. half 10 - with the atmosphere. The locking and pressing elements 11, 12 are connected with the partition 8. In K 1, a hole 13 is made below its upper point, the cross section is equal to the cross section of the casing 7. The casing 7 is connected to K 1 along the perimeter, the hole 13. The partition 8 can be used. Made of either an elastic material or corrugated rubber. 1 hp f-ly, 2 ill. yu (L
