Устройство относится к отрасли машиностроения, а именно к арматуростроению и может быть использовано в качестве запорной арматуры на трубопроводах АЭС, ТЭС, магистральных нефте- и газопроводах. В устройстве снижение интенсивности износа сопрягаемых плоских рабочих поверхностей подъемного шибера и уплотнительных седел достигается за счет того, что в зону сопряжения рабочих поверхностей подъемного шибера и уплотнительных седел входного и выходного патрубков подается под давлением рабочая среда, выполняющая роль смазки.

Принадлежит: Анатолий Андреевич Аниканов, Валерий Павлович Евтеев

Устройство относится к области арматуростроения и предназначено для перекрытия и регулирования расходов потоков жидких и газообразных сред, в том числе абразивных, агрессивных и взрывоопасных, в различных технологических линиях.Прямоточный затвор содержит корпус в виде узкого цилиндрического кольца, в который устанавливается пакет из двух притертых дисков. Диски с выполненными в них профильными окнами стягиваются с определенным усилием при помощи оси. Один из дисков в корпусе фиксируется винтами и становится неподвижным. Второй диск подвижный через шарнирную тягу тангенциально соединяется со штоком внешнего привода. Герметичность штока внешнего привода обеспечивается сальниковым узлом.Простота конструкции делает затвор надежным, долговечным и восстанавливаемым изделием.

Полезная модель относится к устройству для повышения ресурса работы и защиты отбойника локализатора и создания замкнутого пространства зоны подрыва при уничтожении элементов боеприпасов сложной конструкции.Целью полезной модели является шибер для повышения ресурса работы отбойника локализатора при уничтожении элементов боеприпасов сложной конструкции.Задачей полезной модели является повышение ресурса работы отбойника локализатора в процессе уничтожения элементов боеприпасов сложной конструкции.Технический результат полезной модели достигается за счет шибера 1 (фиг. 1), который повышает ресурс работы отбойника локализатора при уничтожении элементов боеприпасов сложной конструкции. Шибер выполнен из горячекатаной стали марки 16 ГС в виде листа прямоугольного сечения (560×380×40 мм) с односторонним скосом под углом 12°, имеет 71 дросселирующее отверстие 2 (фиг. 1) диаметром 20 мм, просверленное под углом 12° к передней плоскости, и предназначен для плавного гашения энергии взрыва, образующейся при уничтожении элементов боеприпасов сложной конструкции. Шибер 1 (фиг. 1) крепится к отбойнику с помощью шпилек через соединительные отверстия 3 (фиг. 1). Скосы шибера совмещаются со скосами торцевых стенок локализатора, что предотвращает разлет осколков и повреждение стенок внутри камеры.Технический результат - повышение ресурса работы и защиты отбойника локализатора и создание замкнутого пространства зоны подрыва при уничтожении элементов боеприпасов сложной конструкции.

Полезная модель относится к гидротехнике, а именно к герметичным запорным устройствам, применяемым в камерах канализационных самотечных каналов и очистных сооружений водопровода. Щитовой затвор содержит смонтированный на трубопроводе или закрепленный на стенке коллектора корпус, имеющий направляющие, в которых установлен связанный с подъемным устройством подвижный щит. Корпус и щит затвора выполнены из полимерного материала - полиэтилена ПЭ-500. Наиболее ответственные, обеспечивающие работоспособность затвора детали, такие как стальной силовой каркас щита, ходовая передача винт-гайка и опорный сферический вкладыш подшипника скольжения размещены в герметичных полостях щита и подшипниковой опоры, тем самым изолированы от воздействия агрессивной рабочей среды. Ходовая гайка и сферический вкладыш подшипника скольжения выполнены из химически стойкого композитного материала, а ходовой винт из кислотостойкой нержавеющей стали, что исключает возможность их коррозии в случае контакта с агрессивной рабочей средой. Примененный композитный материал обладает антифрикционными свойствами, обеспечивающими работоспособность подъемного устройства при полном отсутствии смазки этих узлов.

Автор: Юрий Васильевич Кузнецов, Юрий Николаевич Парамонов
Принадлежит: Общество с ограниченной ответственностью "Завод нефтегазового оборудования "ТЕХНОВЕК"

Полезная модель относится к трубопроводной арматуре. Задвижка штуцерная, состоящая из двух полукорпусов, в которых установлены седла с проходными каналами, между полукорпусами размещен поворотный шибер со сменным штуцером. Фланцевая часть полукорпуса, удерживающая шибер и седла, соосно сопряжена конусом с проходной трубой с уклоном. Выход вала из корпуса оформлен кольцевой резьбовой крышкой с надписями на наружном торце, на которые указывает заостренная часть рукоятки.

Embodiments relate to valves comprising a member such as a plate or poppet, that is moveable relative to a stationary seat. The state of the member may be maintained against opposing forces with relatively little expenditure of energy. According to one embodiment, a poppet displaced from seating in the valve seat, may be held in position against opposing forces tending to close the valve, until a desired flow of gas through the valve has taken place. The poppet may then be released as desired, such that those opposing forces serve to passively close the valve. The valve may be secured in position utilizing mechanical, magnetic, electromagnetic, pneumatic, electrostatic, or hydraulic approaches. Valve embodiments may be particularly suited to controlling gas flows for compression and/or expansion in an energy storage system.

A gate valve assembly comprises a valve body with an inlet and an outlet and first and second valve elements which are located between the inlet and the outlet . The first valve element is engageable with and disengageable from the second valve element . The second valve element is in sliding contact with the valve body and is slidable between a first position in which the second valve element prevents flow from the inlet to the outlet and a second position in which the second valve element permits flow from the inlet to the outlet . An actuator is operable to move the first and second valve elements . The assembly is configured to provide a first flow path from the inlet to the outlet when the first valve element is disengaged from the second valve element , and to provide a second flow path from the inlet to the outlet when the second valve element is moved from the first position to the second position.
