VALVE WITH ROD DRIVE THROUGH SEALING ELASTIC PARTITION Russian patent published in 2019 - IPC F16K39/02 

FIELD: machine building.

SUBSTANCE: valve with rod drive through sealing resilient partition relates to chemical engineering, nuclear engineering, to the construction of shutoff valves of pipelines for pumping toxic liquids into sealed vessels, where high pressure processes are carried out in order of 200–300 atm. Longevity increase and reduction of labour intensity is ensured by implementation of generator of radial forces in the form of U-shaped rocker 6 rigidly connected with drive shaft 3 with cages 8 fixed on its ends, in which rollers 19 are mounted. Rollers 19 are installed parallel to stock 9. Rollers 20 are installed parallel to inner wall of housing 1. U-shaped balance arm 6 is connected with adjusting nut 12.

EFFECT: increased durability and reduced labour intensity.
