For achieving the above object, the utility model is achieved through the following technical solutions: a kind of electromagnetic exhaust valve with filtrating equipment, comprise housing, coil holder, coil, mangetic core assembly, suction tude, outlet pipe, bonnet, coil is enclosed within the outer surface of coil holder, coil holder has a center hole to be connected with outlet pipe, coil holder is erected between housing and the bonnet, mangetic core assembly is installed in the endoporus of coil holder, described mangetic core assembly comprises the rubber seal piece, movable core, spring, secured core, the rubber seal piece is fixed on the front end of movable core, secured core has a center hole, the suction tude fore-end is stuck between bonnet and the secured core center hole, the end face of suction tude and secured core attachment portion is provided with a filter sheet, and spring is against between filter sheet and the movable core rear end, and the movable core rear end has gas port.

The said fixing core exterior surface is fluted, and O type circle is housed on the groove, and O type circle is clipped between groove and the coil holder endoporus.

Above-mentioned suction tude is fluted with the outer surface that the secured core center hole is connected, and O type circle is housed on the groove, and O type circle is clipped between groove and the secured core center hole.

Above-mentioned coil holder and outlet pipe are connected as a single entity.

The electromagnetic exhaust valve of above-mentioned band filtrating equipment, described suction tude back end outer surface also connects a nut, places an O type circle in the endoporus of nut, and the outer surface that suction tude cooperates with nut is fluted, O type circle is housed on the groove, and O type circle is clipped between groove and the nut.

The electromagnetic exhaust valve of above-mentioned band filtrating equipment is stamped a projection after described, and the described nut edge that keeps to the side has individual hole, and the projection of bonnet matches with the nut edge hole.

This kind electromagnetic exhaust valve is because the end face in suction tude and secured core attachment portion is provided with a filter sheet, and the gas that enters solenoid valve all will guarantee to discharge the quality of gas through the filtration of filter sheet; The endoporus of coil holder and mangetic core assembly just constitute the major component of valve body and coil holder and exhaust port and are connected as a single entity, structure is comparatively simple, at the secured core outer surface O type circle is installed, in suction tude and secured core center hole joint O type circle is set, can prevent that gas is from leaking between secured core and the coil holder bore area or from suction tude and secured core center hole joint, connect a nut in the suction tude back end outer surface, placing an O type circle in the endoporus of nut can make things convenient for and being connected of gas container, easy for installation, can prevent that in projection of bonnet processing and the cooperation of nut edge hole nut from skidding on suction tude, the outer surface that suction tude cooperates with nut is provided with O type circle can prevent that gas from leaking to suction tude and nut cooperation place from container.
