GAS-PRESSURE REDUCER Russian patent published in 2017 - IPC G05D16/06 

FIELD: physics.

SUBSTANCE: gas-pressure reducer comprises a housing with an inlet opening for feeding high-pressure gas, in which is hermetically installed a sleeve with a locking seat, inside of which there is a slide valve pressed to the seat of the sleeve by a locking spring, the locking air-tightness is provided by a plastic insert which is canted into the body of the valve. A sensitive element installed in the cover of the reducer, which detects the drop between gas pressure at the output of the reducer and atmospheric pressure or pressure, relative to which output pressure of the reducer is maintained, consists of a metal corrugated bellows with a hermetically installed plug and a banding bushing with a rubber seal, inside of which there is an adjustment spring, which is tightened by a packing nut, wherein the force from the adjustment spring and the bellows of the sensitive element is transferred to the valve by a pusher, which passes through a guide washer inside the opening of the seat of the sleeve, and reduced gas exits the housing through the inlet nozzle.

EFFECT: invention prolongs the service life of the gas-pressure reducer.
