Abstract

Винахід належить до залізничного транспорту, зокрема до ущільнення для керуючих клапанів та керуючого клапана з ущільненням для керуючого клапана. Ущільнення містить кільцевий основний корпус (76), обмежений в аксіальному напрямку двома протилежними сторонами, а в радіальному напрямку - стороною, спрямованою радіально назовні, і стороною, спрямованою радіально всередину. В одній з аксіальних сторін по колу основного корпусу (76) сформована пружинна канавка (80), яка на одній радіальній стороні основного корпусу (76) утворює робочу ущільнювальну кромку (78), і щонайменше одне повітровипускне з'єднання (84, 86) між однією з радіальних сторін та однією з аксіальних сторін. Повітровипускне з'єднання (84, 86) містить щонайменше одну повітровипускну канавку. Щонайменше одна повітровипускна канавка щонайменше одного повітровипускного з'єднання (86) проведена по аксіальній стороні, яка є аксіально протилежною пружинній канавці (80), що проходить по колу основного корпусу (76).The invention relates to railway transport, in particular to seals for control valves and a control valve with a seal for a control valve. The seal comprises an annular main body (76) bounded in the axial direction by two opposite sides, and in the radial direction by a side directed radially outwards and a side radially inward. In one of the axial sides along the circumference of the main body (76) is formed a spring groove (80), which on one radial side of the main body (76) forms a working sealing edge (78), and at least one air outlet connection (84, 86) between one of the radial sides and one of the axial sides. The air outlet connection (84, 86) comprises at least one air outlet groove. At least one air outlet groove of at least one air outlet connection (86) is made on the axial side, which is axially opposite to the spring groove (80) extending around the circumference of the main body (76).
