Description

Изобретение отн€х:итс  к устройствам дл  перекрыти  трубопровоцов, а именно к эпастичным клапанам, размещенным в канапе трубопроводов.The invention relates to devices for shutting off pipelines, in particular to epastic valves located in a canape of pipelines.

Известно устройство цп  перекрыти  трубопровода, содержащее кпапан, состо щий из поспедоватепьного р да скрепленных между собой полых эластичных баплонов, насос дл  создани  дапорногр давлени  и шланг, соедиа « ший Haccjc с клапаном 1.It is known a piping device to shut off a pipeline, which contains a valve, consisting of a continuous series of hollow elastic baplon fastened together, a pump for creating a pressure drop and a hose connecting Haccjc with valve 1.

Недостатком известного устройства  вп етс  то, что каждый из баллонов имеет автономный шланг дл  раздельной подачи запорного давлени  в полости.A disadvantage of the known device is that each of the cylinders has an autonomous hose for separately supplying the locking pressure in the cavity.

Поскольку давление в клапане должно значительно превосходить запираемое давление в трубопроводе, :в известном устройстве затруднено перекрытие высоких рабочих давлений, так как увеличение прочности стенок баллонов снизит их эластичность. Кроме того, наличие множества устройств дл  раздельной управл емой подачи запорного давлени  вSince the pressure in the valve must significantly exceed the lockable pressure in the pipeline, in a known device it is difficult to overlap high operating pressures, since increasing the strength of the walls of the cylinders will reduce their elasticity. In addition, the presence of a variety of devices for separately controlled supply of shut-off pressure in

баллоны усложн ет конструкцию и снижает надежность его эксплуатации.cylinders complicates the design and reduces the reliability of its operation.

Цепь изобретени  - повыщение на- дежности устройства.The circuit of the invention is to increase the reliability of the device.

Поставленна  цель достигаетс  тем, что полости соседних баллонов соединены между собой дроссел ми, причем ишанг соединен с полостью первого баллона, расположенного со стороны рабочего давлени  в трубопроводе, а полость последнего баллона соединена дроссевем с полостью трубопровода.The goal is achieved by the fact that the cavities of the adjacent cylinders are interconnected by throttles, with the ishang connected to the cavity of the first cylinder located on the side of the working pressure in the pipeline, and the cavity of the last cylinder is connected to the cavity of the pipeline by throttle.

При этом по меньшей мере, один дроссель снабжен редукционным клапаном.In this case, at least one choke is equipped with a pressure reducing valve.

На чертеже изображена схема устр 1ства в разреза вдоль оси трубопровода.The drawing shows a diagram of the device in a section along the axis of the pipeline.

В трубопроводе 1 с помощью троса 2 укреплен р д баллонов 3,4 и 5, торцы которых соединены между собой. In the pipeline 1 by means of a cable 2 a series of cylinders 3, 4 and 5 are fastened, the ends of which are interconnected.

Внутренние полости баллонов сообшаютс  между собой с помощью дросселей 6 и 7. Первый баллон 3 соединен с васосом (на схеме не показан) с помошы шпавга 8.The internal cavities of the cylinders are communicated with each other by means of chokes 6 and 7. The first cylinder 3 is connected to the pump body (not shown in the diagram) by means of a screw 8.
