FIELD: machine building. ^ SUBSTANCE: gate is proposed for overlapping and regulating of actuating medium flow, transported by pipeline. The gate contains casing, disk-shaped rotary sluice, saddle and sealing element. The latter is implemented in the form of multiple sandwich of interlace metallic rings and rings from thermo-extended graphite, additionally correlation of its thicknesses is not less than 1:1.5 agreeably. ^ EFFECT: enhanced reliability. ^ 3 cl, 5 dwg |
