Description

Известны шланговые краны дл  перекрыти  трубопроводов с рубашкой, охватывающей шланг и пережимаемой тросом.Hose valves are known for shutting off pipelines with a jacket covering a hose and a pinch cable.

Предлагаемое устройство отличаетс  от известного тем, что рубашка- кожух выпол- нена конической формы, постепенно сужающейс  и со скругленными кра ми.The proposed device differs from the known one in that the jacket-casing is conical in shape, gradually tapering and with rounded edges.

Така  форма кожуха при деформации обеспечивает наиболее оптимальный профиль пережимаемого шланга, тем самым уменьшаетс  гидравлическое сопротивление.This casing shape during deformation provides the most optimal profile of the clamped hose, thereby reducing flow resistance.

На фиг. 1 показан предлагаемый кран, продольный разрез; на фиг. 2 - продольный разрез крана при частичном перекрытии потока с образованием коноидального сечени .FIG. 1 shows the proposed crane, longitudinal section; in fig. 2 is a longitudinal section of the crane with a partial overlap of the flow with the formation of a conoidal section.

В корпусе 1 выполнена горловтгаа 2 с рифлени ми 3. Внутри корпуса 1 расположен эластичный шланг 4 с коноидальной рубашкой-кожухом 5, образуюшей герметичную , заполненную жидкостью полость 6. Кожух 5 охватываетс  тросом 7, в которыйIn the housing 1 there are made gorlovtga 2 with grooves 3. Inside the housing 1 there is an elastic hose 4 with a conoidal jacket-casing 5 forming an airtight cavity filled with fluid 6. The casing 5 is covered by a cable 7 in which

тродета штанга 8. При необходимости изменени  расхода жидкости или перекрыти  потока вращают штангу 8, скручива  трос 7, который- пережимает рубашку-кожух 5. При этом жидкость в герметичной полости 6, воздейству  на шланг 4 деформирует его, придава  пережимаемому участку шланга коноидальный профиль. .If necessary, changing the flow rate or blocking the flow, rotate the rod 8, twisting the cable 7, which pinches the jacket-casing 5. At the same time, the liquid in the sealed cavity 6, acting on the hose 4 deforms it, giving the conical profile to the clamped part of the hose. .

Необходимый расход жидкости фиксируетс  установкой штанги 8 в рифлени х 3. The required flow rate is fixed by mounting the rod 8 in the corrugations 3.

Предмет изобретени Subject invention

Пережимаюш.ий кран, в корпусе которого расположен шланг, окруженный рубашкой - кожухом из эластичного материала с жидкостью внутри, пережимаемый тросом, отличающийс  тем, что, с целью снижени  гидравлического сопротивлени , кожух выполнен конической формы, постепенно сужающимс  и со скругленными кра ми.Pinch valve, in the case of which there is a hose surrounded by a jacket - with a casing of elastic material with liquid inside, pinched by a cable, characterized in that, in order to reduce flow resistance, the jacket is made conical in shape, gradually tapering and with rounded edges.
