Abstract

The invention discloses a control valve for an automobile gas electric control operation. The control valve for the automobile gas electric control operation comprises an adjusting screw, an adjustingspring, a small diaphragm, a secondary valve clack, a primary valve clack and a large diaphragm; the adjusting screw penetrates through a top cover of a valve seat and is connected with the adjustingspring; the lower end of the adjusting screw is connected with the secondary valve clack through the small diaphragm; the secondary valve clack is connected with the primary valve clack through a spring; the lower end of the primary valve clack is connected with a connecting pipe; the connecting pipe is connected with the large diaphragm; and the adjusting spring, the small diaphragm, the secondary valve clack, the primary valve clack and the large diaphragm are all positioned in the valve seat. According to the technical scheme, an adjusting valve and a pressure reducing valve which reduce the inlet pressure of fluid and automatically maintain the inlet pressure at a certain required outlet pressure by utilizing a throttling principle are mainly applied to steam supply, gas supply, watersupply and oil supply systems.

Description

technical field [0001] The invention relates to the technical field of gas, in particular to a control valve for electric control operation of automobile gas. 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 injection system of th...
