Полезная модель относится к трубопроводной арматуре, а именно к шаровым кранам, предназначенным для перекрытия потоков рабочей среды, транспортируемой по технологическому трубопроводу. Шаровой кран содержит корпус с проходным каналом, имеющим вход и выход. В указанном канале размещен в двух седлах сферический запорный орган, выполненный со сквозным отверстием для прохождения рабочей среды. Сферический запорный орган связан с приводом его вращения между закрытым и открытым положениями шарового крана. При этом внутри сферического запорного органа выполнена кольцеобразная разгрузочная камера, соединенная по меньшей мере двумя промежуточными проточками с входным отверстием. Кольцеобразная разгрузочная камера имеет разгрузочную поверхность в виде кольца, лежащую в плоскости, параллельной плоскости, проходящей через ось сквозного отверстия сферического запорного органа и ось привода его вращения, и расположенную в закрытом положении шарового крана со стороны входа проходного канала, а входное отверстие соосно проходному каналу корпуса. Предлагаемая конструкция шарового крана позволяет повысить надежность функционирования шарового крана при высоких давлениях рабочей жидкости, увеличить срок его службы при сохранении высокой герметичности за счет уменьшения износа уплотнительных поверхностей сферического запорного органа и седел, в которых он расположен, уменьшения усилий на приводе вращения сферического запорного органа при его открывании при несложной конструкции и низкой себестоимости шарового крана. 3 ил.

Valve for powder

Номер: US20120037833A1
Автор: Shigeo Fukui, Shinji Takahashi, Takashi Arai, Takayuki Miyazaki, Yasuhide Takeda
Принадлежит: Mitsui Engineering and Shipbuilding Co Ltd

A powder valve is propose which is simple in structure and small in size, which can prevent powder from getting stuck in the valve, and can withstand high feed pressure. The valve includes a valve casing 21 , a valve shaft 25 , and a valve body 22 mounted in the valve casing 21 and supported by the valve shaft 25 . The valve body 22 has a spherical outer surface 27 configured to be brought into contact with a valve seat 23 of the valve casing 21 to close the valve. The valve body 22 is formed with a communication hole 26 extending in a direction perpendicular to the valve shaft 25 so that when the valve body 22 is rotated about the valve shaft 25 in either of two opposite directions from the closed position, the valve is configured to open through the communication hole 26 . The communication hole 26 is open on the back side of the valve body 22 over the entire length thereof. With this arrangement, it is possible to ensure the advantages of a ball valve, i.e. full-bore properties and high rigidity. Since the pressure of powder flowing through the communication hole 26 acts on the inner periphery of the valve casing 21 , the flow of powder blows off and removes any powder which could otherwise get stuck on the inner periphery of the valve casing 21 . By rotating the valve body 22 in both directions, powder can be removed on both sides of the valve shaft 25.

A valve with a dual rotational valve member is provided. The valve includes a first valve member and a second valve member. An actuation arrangement is operably positioned between the first valve member and the second valve member to rotate the first valve member in a first direction and the second valve member in a second direction opposite the first direction. This counter-rotation of the first and second valve members selectively aligns or misaligns a pair of flow ports of the first valve member with a pair of flow ports of the second valve member. When the pairs of flow ports are aligned, the flow path of the valve allows for straight through flow of a fluid through the valve thereby decreasing turbulence, back pressure, and noise.
