As shown in Figures 2 to 4, a kind of secondary air solenoid valve described in the utility model and one-way valve integral structure, comprise solenoid valve and be sleeved on the one-way valve in solenoid valve cavity, described solenoid valve comprises valve body 3 and the dynamic iron core 4 that is arranged on respectively in valve body 3 and fixed core 6, described valve body 3 foreign volume is wound with coil 9, valve body 3 top is provided with support 8, described valve body 3 inside is provided with upper chamber 110 and lower chambers 120, described dynamic iron core 4 and fixed core 6 are arranged in upper chamber 110 respectively, suction port 101 and air outlet hole 102 is respectively arranged with lower side bottom described valve body 3, the sealing active door 1 be connected with one-way valve is also provided with in described lower chambers 120, sealing active door 1 is set with spring A2, described dynamic iron core 4 is also set with spring B 5.
Described valve body 3 is positioned at coil 9 lower end and is provided with fixed plate 10.
O type circle 7 is set with outside described fixed core 6.
The upper chamber 110 of described valve body 3 is provided with step hole 111.Be convenient to the location that fixed core 6 assembles.
Described fixed core 6 is provided with annular groove.Be convenient to assembling O type circle 7, reach product seal request.
Described dynamic iron core 4 is stepped stem structure.Like this, be not only convenient to the location that spring B 5 is assembled, dynamic iron core 6 back and forth movement back and forth can be realized again, reach the object of optimizing structure.
Be press-fitted connecting-tube nozzle 11 bottom the lower chambers 120 of described valve body 3 and be combined to form suction port 101, and connecting-tube nozzle 11 and sealing active door 1 form the sealing surface of one-way valve module.When sealing surface is opened, suction port 101 and air outlet 102 conducting; When sealing surface is closed, suction port 101 and air outlet 102 are closed.
