FIELD: metallurgy. ^ SUBSTANCE: invention relates to metal casting. Fluid circulation main route is connected to refractory element with parallel hole on its surface, device, containing cushion, rod with confidence channel for fluid leaking and two bearing elements. Cushion is located in the hole of refractory element between the first bearing element from the outside of the hole and the second bearing element located inside the hole. Rod provides approaching of two bearing elements and apply axial pressure to cushion, activating its radial expansion and abutment to the hole wall. ^ EFFECT: it is provided simplicity, compactness and leaktightness of connection of fluid circulation main route with refractory element . ^ 11 cl, 2 dwg |
