Abstract

1. Вентиль, например, для вакуумных установок, в котором уплотненный сильфоном запорный орган выполнен подвижным в осевом направлении и принудительно фиксируемым в положении "закрыто", отличающийся тем, что, с целью повышения герметичности вакуум-плотного перекрытия, на рабочей (торцовой) поверхности запорного органа выполнен цилиндрический выступ, вдавливаемый в уплотняющую прокладку, расположенную на таком же цилиндрическом выступе, выполненном на седле, причем контактные поверхности уплотнительных выступов и прокладки покрыты металлическим герметизирующим слоем.2. Вентиль по п.1, отличающийся тем, что, с целью повышения его быстродействия, на конце запорного органа, противоположном его рабочей части, расположена поворотная втулка с укрепленным на ней рычажным ключом, рычаги которого взаимодействуют с корпусом вентиля и служат для досылки запорного органа в направлении "закрыто" по скосам байонетного замка, которым снабжена втулка.3. Вентиль по пп.1 и 2, отличающийся тем, что прокладка вентиля снабжена кольцевыми проточками под кольцевые выступы седла и запорного органа и имеет толщину h, примерно равную радиальной ширине b выступов, которая выбрана по формуле b ≈ (0,005Д + 0,6) мм, где Д - средний диаметр кольцевых выступов.1. A valve, for example, for vacuum installations, in which the valve body compacted with a bellows is made movable in the axial direction and forcibly fixed in the "closed" position, characterized in that, in order to improve the vacuum-tight closure, on the working (end) surface the locking member has a cylindrical protrusion pressed into a sealing gasket located on the same cylindrical protrusion made on the saddle, and the contact surfaces of the sealing protrusions and gaskets are covered with metal with a plastic sealing layer. Valve according to claim 1, characterized in that, in order to increase its speed, at the end of the locking member opposite to its working part, there is a rotary sleeve with a lever key fixed on it, the levers of which interact with the valve body and serve to feed the locking member the direction is "closed" along the bevels of the bayonet lock with which the sleeve is fitted. Valve on PP.1 and 2, characterized in that the valve gasket is provided with annular grooves under the annular protrusions of the saddle and valve body and has a thickness h approximately equal to the radial width b of the protrusions, which is selected by the formula b ≈ (0.005D + 0.6) mm, where D is the average diameter of the annular projections.
