Abstract
The utility model relates to a two-position three-way normally-closed control electromagnetic valve. The two-position three-way normally-closed control electromagnetic valve comprises an electromagnetic coil, a push rod, an air inlet and an air outlet and is characterized in that a valve and a valve seat are arranged, wherein a sealing effect is realized by a sealing surface on the valve and a sealing lip on the valve seat; and a spring and a small spring are arranged to realize returning. The two-position three-way normally-closed control electromagnetic valve has the advantages that with the planar sealing, the resistance to the motion of a piston can be effectively reduced, and the effective drift diameter of the electromagnetic valve can be increased; the section of the sealing lip has an acute-angle fillet structure, so that the sealing is reliable, and the rubber on the sealing surface cannot be cut easily; the two-position three-way normally-closed control electromagnetic valve is compact in structure and easy to assemble; and the design and positions of the air inlet and the air outlet can play a role of cleaning two sealing surfaces of the piston, so that the fouling resistance of a product can be improved.
Description
Technical field
The utility model application relates to a kind of special vehicle with the normally closed control electromagnetic valve of two-position three way, is used for the opening and closing of solenoidoperated cluthes cylinder.Belong to field of fluid machinery.
Background technique
There is the defective that assembly process process is poor, O shape is enclosed the motion via hole in existing military special vehicle with solenoidoperated cluthes cylinder opening and closing solenoid valve.In the electromagnetic valve switch process, O shape circle rubber pressurized is easy to generate extrusion-deformation and gets into institute's small holes, thereby significantly increases the piston action resistance, and causes O shape circle to be cut damage, the phenomenon of mechanism blockage.This structure is affected by environment simultaneously, and the packing grease on the O shape circle is contaminated easily, causes sealability and reliability all relatively poor.
Summary of the invention
The purpose of the utility model provides that a kind of assembly process process is good, sealing reliability can be high, stain resistance is strong, the flame-out solenoid valve of reliable in action.
The technological scheme of the utility model is: the normally closed control electromagnetic valve of two-position three way, comprise electromagnetic coil, push rod, suction port and air outlet, and it is characterized in that: be provided with valve and valve base, sealing surface on the valve and the seal lip on the valve base realize sealing; Being provided with spring and little spring realizes resetting.
The beneficial effect of the utility model is: adopt the plane sealing pattern, can effectively reduce the piston motion resistance, and help increasing the solenoid valve effective drift diameter.Acute angle rounding type structure is adopted in the seal lip cross section, and sealing is reliable and be difficult for cut wound sealing plane rubber.Compact structure, assembling is simple.The valve sealing surface with metal edge boss protection, can be avoided the erosion of high-speed gas with sulfuric horizon, improves piston working life, and rubber adopts the higher material of Shao's formula hardness simultaneously, can effectively avoid the aging distortion of rubber to cause seal failure.The cleaning action to piston two sealing surfaces can be played in suction port and vent design and position, thereby improves the product stain resistance.

Fig. 2 is the structural representation of like product in the past.
Embodiment
Embodiment: valve 1 is under spring 2 effects during outage, and its sealing surface 3 cooperates with the seal lip 5 of valve base 4 realizes sealing, is disconnected between pressurized gas suction port 6 and the air outlet 7, and this moment, vehicular clutch was in off state.
After electromagnetic coil 8 energisings; Push rod 9 can move down; Move to certain stroke, push rod 9 will contact and promote the active force that valve 1 overcomes spring 2 with the sealing surface 3 of valve 1 and also move downward, and the sealing surface 3 and the seal lip 5 of valve base 4 are thrown off; Gas circuit between suction port 6 and the air outlet 7 is connected, and pressurized gas arrives the clutch operating tube through this valve makes clutch be in engagement.
After electromagnetic coil 8 dead electricity, under the effect of little spring 10, push rod 9 can reset.Valve 1 also can reset under the effect of spring 2 simultaneously.
Claims (1)
1. the normally closed control electromagnetic valve of two-position three way comprises electromagnetic coil, push rod, suction port and air outlet, it is characterized in that: be provided with valve and valve base, sealing surface on the valve and the seal lip on the valve base realize sealing; Being provided with spring and little spring realizes resetting.
