Corrosion resistance precision gas voltage regulator

Abstract

The invention relates to a corrosion resistance precision gas voltage regulator; in the regulator, a flat plate is fixed above a gas tank; a membrane on the flat plate is provided with a through hole so that the gas tank is communicated with the membrane; a zero position cavity cover covers the upper side of the membrane; the bottom end of a lower need-shaped rod is put on the upper surface of the membrane; the top end of the lower need-shaped rod props up a landing leg of a lever of a sensor; the bottom end of an upper need-shaped rod is put on the other landing leg of the level of the sensor; the top end of the upper need-shaped rod props up one end of a small lever; the other end of the small lever is rested on a small ball which is arranged on an airflow tube; the upper side of the airflow tube corresponds to one end of a big level; the other end of the big lever is connected with a steering yoke; the lower part of the airflow tube is arranged in a servo device and drives a disc seat to move through the elongation or contraction of a spring box of the servo device fixed on the disc seat, thereby driving the airflow tube to move up and down in a shell of the servo device. The regulator can realize the automatic regulation of pressure in strong corrosive gas medium, has constant voltage function and high voltage regulation precision and is stable in running.

Description

technical field [0001] The invention relates to a gas pressure stabilizing device, in particular to a precision device for automatically adjusting the pressure of a strongly corrosive gas medium. Background technique [0002] Chinese patent (patent No. 200680009421.4) discloses a gas pressure regulator, which moves longitudinally on the first limit line through a throttle to change the size of the throttle opening and adjust the gas throughput. Resisting the throttle movement is the regulator spring unit. [0003] Chinese patent (patent number is 01803599.x) also discloses another kind of pressure regulator, by controlling the closure at the pressure medium inlet, a valve spring is supported on the closure, and the other end of the valve spring is supported in the spring guide sleeve . When the pressure changes, the valve spring is compressed or extended, and the closure member opens or closes to adjust the gas throughput. [0004] The existing gas pressure stabilization ...

Problems solved by technology

[0004] The existing gas pressure stabilization device, when using a strong corrosive gas medium, its pressure sensing elements are all spring elements and directly act on the closing element, which is easily affected by corrosive gas. The overall structure is simple, but it has low precision, short life, and long-term Poor operation stability and other shortcomings, not suitable for long-term stable use under special gas medium conditions
