Description
Изобретение относитс к холодильной и криогенной технике.The invention relates to refrigeration and cryogenic technology.
Цель изобретени - повышение эксплуатационной надежности.The purpose of the invention is to increase operational reliability.
На чертеже изображена схема дроссельного устройства.The drawing shows a diagram of the throttle device.
Устройство содержит корпус 1, в котором расположены седло 2 с центральным отверстием и уплотнительной поверхностью тороидальной формы, подпружиненный пружиной 3 сферический клапан 4, гибка перего- редка 5, поджата пружиной 6, и ограничитель хода клапана 7. Пружина 3 опираетс на розетку 8, закрепленную на седле 2.The device includes a housing 1 in which a saddle 2 with a central hole and a toroidal-shaped sealing surface are located, spring-loaded 3 with a spherical valve 4, flexible to change 5, preloaded with spring 6, and valve-stroke limiter 7. Spring 3 is supported on the socket 8 fixed on the saddle 2.
Устройство работает следующим образом.The device works as follows.
Через входной штуцер подаетс газ высокого давлени . В дроссельном устройствеHigh pressure gas is fed through the inlet fitting. In the throttle device
он дросселируетс через щель, образованную торовой поверхностью седла 2 и сферической поверхностью клапана 4. После дросселировани газ выходит через выходной щтуцер. При забивке дроссельной щели давление перед клапаном 4 возрастает и сжатый газ перемещает подвижное основание гибкой перегородки 5. Клапан 4 тоже перемещаетс , но до тех пор, пока не упретс в ограничитель хода клапана 7, а гибка перегородка 5 перемещаетс дальше, дроссельна щель увеличиваетс и посторонние частицы унос тс потоком газа.it is throttled through a gap formed by the torus surface of the seat 2 and the spherical surface of the valve 4. After throttling, the gas exits through the outlet plug. When the throttle slit clogs, the pressure upstream of the valve 4 increases and the compressed gas moves the movable base of the flexible baffle 5. The valve 4 also moves, but until it stops at the valve stroke limiter 7 and the baffle 5 moves further, the throttle slit increases and the extraneous particles carried away by the gas flow.
При достижении рабочего давлени клапан и седло возвращаютс в исходное положение пружинами 3 и 6.When the working pressure is reached, the valve and seat are returned to their original position by springs 3 and 6.
