Abstract
Изобретение относитс к области машиностроени и может быть использовано дл защиты напорных водоводов от гидравлических ударов, начинающихс с понижением давлени . Целью изобретени вл етс повышение надежности работы. При стациомаркой работе основна часть жидкости поступает к потребителю, а часть за счет разности скоростных напоров циркулирует в открытой колонне 2, установленной на уча- стке 1 трубопровода с изломом. Циркул ци жидкости исключает замерзание жидкости при отрицательных температурах, при этом уровень жидкости отслеживаетс с помощью поплавковых элементов 5, св занных с гофрированной оболочкой 4, закрепленной на полой трубе 3. Также дл исключени замерзани часть верхнего конца колонны 2 внутри покрыта гидрофобным материалом, а снаружи утеплителем 6. Повышени надежности работы при пуске насоса обеспечиваетс компенсацией отрицательного давлени (вакуума) в изломе и снижает отрицательный гидравлический удар, а также последующий положительный удар. 2 ил. W feThe invention relates to the field of mechanical engineering and can be used to protect pressure conduits from hydraulic shocks, starting with decreasing pressure. The aim of the invention is to increase the reliability of operation. During the hospital operation, the main part of the liquid goes to the consumer, and part due to the difference in velocity heads circulates in the open column 2, installed on section 1 of the fractured pipeline. The liquid circulation prevents liquid from freezing at negative temperatures, while the liquid level is monitored using float elements 5 associated with the corrugated shell 4 fixed to the hollow pipe 3. Also to avoid freezing, part of the upper end of the column 2 is covered inside with a hydrophobic material, and outside insulation 6. Improving reliability when starting the pump is provided by compensating for the negative pressure (vacuum) in the fracture and reduces the negative hydraulic shock, as well as subsequent th positive blow. 2 Il. W fe
