Abstract

Изобретение относится к уплотнительным системам гидравлических запорных клапанов. В частности, изобретение относится к уплотнительной системе, которая может быть расположена между подвижным исполнительным элементом гидравлического запорного клапана и неподвижным элементом, например, корпусом или кожухом клапана. Согласно изобретению уплотнительная система содержит несколько комплектов уплотнительных колец, которые в совокупности предотвращают утечку текучей среды. Уплотнительная система, в частности, содержит, по меньшей мере, три комплекта уплотнительных колец, приспособленных нагружаться давлением текучей среды по отдельности.
