Description
Предлагаемое устройство работает следующим образом.The proposed device works as follows.
В открытом положении проходной канал 4 шарового запорного органа 3 совпадает с проходным отверстием корпуса 1, обеспечива проход рабочей среды.In the open position, the passage 4 of the ball locking member 3 coincides with the passage opening of the housing 1, ensuring the passage of the working medium.
При повороте штока 8 на четверть оборота проходной канал шарового запорного органа 3 устанавливаетс перпендикул рно проходному отверстию крана.When the stem 8 is rotated by a quarter of a turn, the passageway of the ball valve body 3 is installed perpendicular to the tap hole.
При переключении крана в момент, когда шаровой затвор 3 находитс под уплотн юшей поверхностью колец 2, седло за счет нзгиба и упругих свойств материала стремитс переместитьс в зону сферической поверхности .When switching the valve at the moment when the ball valve 3 is under the sealing of the outer surface of the rings 2, due to the bend and elastic properties of the material, the seat tends to move to the area of the spherical surface.
При этом в работу вступают опорные перегородки 5, которые своей наружной поверхностью , совпадаюш,ей со сферой запорного органа, не дают седлу оказатьс в зоне проходного канала 4. При дальнейилем повороте И1тока 8 поверхность уплотнительного кольца 2 скользит по сферической поверхности перегородок 5, и см ти седла не происходит. При проходе шарового запорного органа от положени открытого к положению закрытому уплотнительна поверхность колец 2 находитс в посто нном контакте со сферической поверхностью запорного органа 3 и перегородок 5, чем обеспечиваетс плавна работа крана на больших скорост х переключени . Така конструкци крана позволит резко повысить срок службы и надежность работы крана, снизить затраты, св занные с ремонтом и сменой уплотнительных колец.In this case, support partitions 5 come into operation, which, by their outer surface, coinciding, with the sphere of the locking organ, do not allow the saddle to be in the area of the passageway 4. With further rotation of Itok 8, the surface of the sealing ring 2 slides along the spherical surface of the partitions 5, and see These saddles do not occur. When the ball valve body passes from the position of the closed to the closed position, the sealing surface of the rings 2 is in constant contact with the spherical surface of the valve body 3 and the partitions 5, which ensures smooth operation of the crane at high switching speeds. This design of the crane will dramatically increase the service life and reliability of the crane, reduce the costs associated with the repair and replacement of the sealing rings.
