Abstract

The invention discloses an operation method of an automobile fuel gas electric control operation control valve. The method comprises the steps that an adjusting screw is unscrewed to open an auxiliaryvalve clack, fuel gas enters the position below a large membrane, the large membrane is moved to open a main valve clack, gas enters the position below a small membrane at the same time, and outlet pressure is adjusted. According to the technical scheme, inlet pressure of fluid is pressed by one half through the throttling principle and automatically kept to an adjusting value with certain neededoutlet pressure. A speed reducing valve is mainly applied to steam, gas, water and oil supply systems.

Description

technical field [0001] The invention relates to the technical field of gas, in particular to an operating method for an automobile gas electric control operation control valve. Background technique [0002] With the rapid growth of car ownership, the problems of environmental pollution and shortage of oil resources are becoming more and more serious. To this end, countries around the world are actively developing new energy vehicles. Among them, natural gas vehicles are being popularized and promoted around the world due to their three major characteristics: low emissions, suppression of greenhouse effect, and independence from oil. In our country, many urban buses and taxis have a large number of fuel vehicles that have switched or are switching to compressed natural gas (CNG) or liquefied petroleum gas (LPG). With the rapid increase in the number of gas vehicles in my country, it is imperative to develop gas heaters that match it. [0003] In the electronic control inje...
