FIELD: valve engineering, gates. SUBSTANCE: at a low pressure of working medium reliable sealing is ensured to provision of several rings in the form of a bipolar magnet. The slide gate has body 1, slide valve 2, two built-up seats 3 and seal 4. Seats 3 consist of several rings 5 in the form of a bipolar magnet, at assembly rings 5 touch one another by like poles. EFFECT: enhanced reliability, simplified design. 1 cl, 1 dwg |
