Problems solved by technology

However, the structure of the injection rail spool in the prior art is complicated, the stability of the nozzle flow is insufficient, and the adjustment of the gas flow is relatively lagging in the adjustment process, such as the gas ejected by the nozzle when increasing or decreasing the flow output. Flow changes slowly

Abstract

The invention discloses an electromagnetic valve for regulating gas flow. The electromagnetic valve comprises an electromagnetic valve seat, wherein a movable valve body and a casing are sequentially arranged in the electromagnetic valve seat from inside to outside, the upper end of the casing extends outwards, a connecting piece with a hollow inner part is arranged at the lower end of the casing, a gap is reserved between the upper end of the connecting piece and the lower end of the movable valve body, a valve mouth is in threaded connection with the extending end of the casing, a gas channel communicated with the middle part of the connecting piece is formed in the movable valve body, a spring is arranged in the gas channel, two through holes communicated with the gas channel are formed in the side wall of the movable valve body, the upper end of the movable valve body is communicated with the inside of the valve mouth, and multiple blowholes are formed in the circumference of the top end of the valve mouth. Compared with the prior art, under the premise of the same increase of gas input, the output of a single gas transmission channel is far lower than that of double gas transmission channels, then the change rate of gas supply quantity of a spray rail car is realized, and the gas flow is flexibly regulated and controlled.

Description

technical field [0001] The invention relates to a gas injection rail, in particular to an electromagnetic valve used for gas flow regulation. 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 the gas fuel engine...
