Abstract

The invention relates to a voltage stabilizer, a gas engine system and a gas pressure control method, wherein the voltage stabilizer includes: a casing, the casing includes an air intake cavity and a piston cavity, the intake cavity and the piston A spacer is provided between the cavities, and an interval through hole is provided on the spacer; a piston, the piston is slidably arranged in the piston cavity, and a piston through hole passing through the piston is provided in the piston; A spring, the spring is arranged in the piston chamber, the spring is arranged between the piston and the spacer; the gas outlet cover is arranged at the open end of the piston chamber, the A gas outlet is provided on the gas outlet cover; an electromagnetic coil is arranged at one end of the gas outlet cover close to the piston, and the electromagnetic coil generates a magnetic field force for attracting the piston when it is energized. To attract the piston to be close to the air outlet cover.

Description

technical field [0001] The invention belongs to the technical field of gas engines, and in particular relates to a voltage stabilizer, a gas engine system and a gas pressure control method. Background technique [0002] At present, the gas nozzles used in natural gas engines can only work well when the internal gas flow velocity is the speed of sound. To ensure the gas flow velocity in the gas nozzle is the speed of sound, it is necessary to ensure that the gas pressure at the nozzle outlet and the nozzle inlet. The gas pressure ratio is less than a fixed value (usually 0.54). [0003] In the natural gas engine system, the inlet of the gas nozzle is connected to the regulator, and the outlet of the gas nozzle is connected to the intake pipe through the mixer, wherein the regulator is used to stabilize the gas pressure at a certain value. The working principle of the existing voltage stabilizer is: high-pressure gas enters the voltage stabilizer, enters the conduit in the mi...
