Abstract

The invention provides a solenoid valve having automatic regulation and control functions. The solenoid valve comprises a control mechanism, a triggering mechanism and an executing mechanism, wherein the control mechanism comprises a bottom casing containing a main circuit board, and two first connecting pipe openings are formed in one side of the bottom casing and are connected with a chip respectively; the triggering mechanism is connected with the control mechanism, a magnet box provided with a pipe opening assembly is arranged on one side of the triggering mechanism, and one end of the pipe opening assembly is connected with one first connecting pipe opening; the executing mechanism is connected with the triggering mechanism, a pipeline is arranged on one side of the triggering mechanism, and a second connecting pipe opening is formed in the pipeline and is connected with the other first connecting pipe opening. According to the solenoid valve having the automatic regulation and control functions, a positive pressure value in the pipeline is detected by the chip and compared with a set positive pressure value, the flow of tail gas is changed, and besides, the position of a fault of the solenoid valve is judged according to positive and negative pressure values detected by the chip.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a solenoid valve, in particular to a solenoid valve with an automatic regulation function. Background technique [0002] Generally, a solenoid valve is installed on the place where the exhaust gas of the automobile leads to the engine, and the commonly used solenoid valve is connected with a vacuum pump, so that a negative pressure is generated in the solenoid valve, so that whether the electromagnet in the solenoid valve is energized or not Change the flow rate of exhaust gas. [0003] However, such a solenoid valve structure cannot monitor the flow of exhaust gas in real time, and the adjustment of the flow of exhaust gas is not accurate. In addition, when the solenoid valve fails, the location and cause of the failure of the solenoid valve cannot be judged in time. [0004] To sum up, in order to solve the shortcomings of the existing solenoid valve structure, it is necessary ...
