Claims (1)

Усовершенствованная система уплотнения для технологического вентиля отличается тем, что промежуточная камера образована между последовательно расположенными скользящими уплотнительными прокладками и соединена со статическим разделителем в виде эластичной камеры давления (или мешка), наполненной способной биологически разлагаться незагрязняющей неагрессивной вспомогательной смазочной текучей средой, причем внутренняя камера давления (или мешок) обладает очень большой эластичностью, соединена с технологической текучей средой и объединена с подвижной головкой, которая соединена с датчиком положения.An improved sealing system for a process valve is characterized in that an intermediate chamber is formed between successively placed sliding gaskets and connected to a static separator in the form of an elastic pressure chamber (or bag) filled with biodegradable non-contaminant non-aggressive auxiliary lubricant fluid or bag) has a very large elasticity, is connected to the technological fluid medium and combined with a movable head, which is connected to the position sensor.
