Integrated steady voltage solenoid valve

The utility model discloses an integrated steady voltage solenoid valve. This integrated steady voltage solenoid valve includes the valve piece, the valve piece seted up with the first valve opening of first solenoid valve complex, the needle pressfitting of first solenoid valve is on first valve opening, with second solenoid valve complex second valve opening, the needle pressfitting of second solenoid valve is on the second valve opening, offered in the valve piece with the communicating decompression valve opening of first solenoid valve, the downthehole relief pressure valve that is equipped with of relief pressure valve, the inlet end and the first solenoid valve of relief pressure valve are connected, the relief pressure valve is provided with the venthole, the venthole is parallelly connected to have the second solenoid valve to connect and first interface, first valve opening is provided with first inlet port. First solenoid valve is opened to the controller of engine during operation automobile, and get into the blast pipe after the interior gas of atmospheric pressure package reduces pressure through the relief pressure valve and blow off out urea, the tail -off, the second solenoid valve is opened to the controller of automobile, and the gas after the second solenoid valve will reduce pressure blows to the urea pipeline, has avoided urea to stop up the urea pipeline.
