Abstract
Изобретение относитс к трубопроводной арматуре. Целью изобретени вл етс повышение надежности работы заслонки путем усили эффекта подпора. В момент закрыти заслонки уплотн ющий элемент 7 прижимаетс к сферической поверхности 14 запорного органа 2. Через зазор между уплотн ющим элементом и запорным органом транспортируема среда попадает в подпорную область, образованную поверхност ми опорного выступа 11 и мембраны 6, при этом поверхность 17 выступа 11 отражает часть потока рабочей среды, преобразу кинетическую энергию потока в потенциальную энергию избыточного давлени . 3 ил.This invention relates to pipe fittings. The aim of the invention is to improve the reliability of the valve by increasing the backpressure effect. At the moment of closing of the valve, the sealing element 7 is pressed against the spherical surface 14 of the locking member 2. Through the gap between the sealing element and the locking member, the transported medium enters the retaining region formed by the surfaces of the support protrusion 11 and the membrane 6, while the surface 17 of the protrusion 11 reflects part of the flow of the working medium, converting the kinetic energy of the flow into the potential energy of excess pressure. 3 il.
