Description
Изобретение относитс к гидромаиностроению и может быть использоано при эксплуатации гидротурбин.This invention relates to a hydro-engine building and can be used in the operation of hydro turbines.
Цель изобретени - уменьшение габаритов устройства дл впуска воздуа в проточную часть гидромашины.The purpose of the invention is to reduce the size of the device for intake air into the flow part of the hydraulic machine.
На чертеже изображена проточна часть гидромашины в месте установки устройства дл впуска воздуха, продольный разрез.The drawing shows the flow part of the hydraulic machine at the installation site of the air intake device, longitudinal section.
Устройство дл впуска воздуха в проточную часть гидромашины содержит трубопровод 1 с вентилем 2, сообщенный с проточной частью 3 и выходом грузового обратного клапана 4, вход последнего сообщен с шахтой 5 гидромашины . Устройство дополнительно содержит охватывающий обратный клапан 4 кожух 6 и размещенный в его полости патрубок 7, сообщенный с шахтой 5. Вход обратного клапана сообщен шахтой 5 через патрубок 7, а трубопровод 1 сообщен с выходом обратного клапана 4 через полость кожуха 6.The device for air intake into the flow part of the hydraulic machine comprises a pipeline 1 with a valve 2 connected to the flowing part 3 and the outlet of the cargo check valve 4, the inlet of the latter communicating with the shaft 5 of the hydraulic machine. The device additionally comprises a casing 6 covering the check valve 4 and a port 7 placed in its cavity, communicated with the shaft 5. The check valve inlet is communicated by the shaft 5 through the pipe 7, and pipe 1 is connected to the outlet of the check valve 4 through the cavity of the casing 6.
При работе гидронашины в проточной части 3 возможно понижение давлени ниже атмосферного. Под действием возникающего перепада давлени открыБаетс грузовой обратный клапан 4, а воздух из шахты 5 гидромашины через патрубок 7, внутреннюю полость кожуха 6 и трубопровод 1 с вентилем 2 попадает в проточную часть 3 гидромашины. При выравнивании давлений в проточной части 3 и шахте 5 грузовой обратный клапан 4 закрьшаетс .When the hydraulic machine is operating in the flow part 3, the pressure may drop below atmospheric pressure. Under the effect of the resulting pressure drop, the cargo check valve 4 is opened, and the air from the shaft 5 of the hydraulic machine through the nozzle 7, the internal cavity of the casing 6 and the pipeline 1 with valve 2 enters the flow-through part 3 of the hydraulic machine. When equalizing the pressures in the flow part 3 and the shaft 5, the cargo check valve 4 is closed.
