The utility model low temperature normal off solenoid directional control valve adopts following technological scheme:
A kind of low temperature normal off solenoid directional control valve is characterized in: solenoid directional control valve comprises base, following rubber membrane piece, moving core, goes up rubber membrane piece, fixed iron core overcoat, fixed iron core, electromagnetic coil; Base is equipped with the fixed iron core overcoat, in moving core is housed, the moving core upside is equipped with fixed iron core, electromagnetic coil is equipped with in the outside; The lower end of following rubber membrane piece and moving core links into an integrated entity, the spring I is connected with following rubber membrane piece, the upper end of spring I is connected with last rubber membrane piece, the upper end of last rubber membrane piece and moving core links into an integrated entity, the spring II is installed on the moving core, the other end of spring II is connected with the fixed iron core overcoat, the boss port valve cock assembling of the relative base of following rubber membrane piece inside.
The utility model low temperature normal off solenoid directional control valve can also be taked following technical measures:
Described low temperature normal off solenoid directional control valve is characterized in: the outer inner room of base and fixed iron core is equipped with seal ring.
Described low temperature normal off solenoid directional control valve, be characterized in: air inlet/outlet is equipped with the protection bolt.
Described low temperature normal off solenoid directional control valve is characterized in: solenoid valve jacking outlet side gas port is equipped with rubber cap.
Advantage that the utlity model has and good effect:
Low temperature normal off solenoid directional control valve, owing to adopted the utility model brand-new technology scheme, compared with prior art, the technical program electromagnetic coil adopts the good resin-cast moulding of electrical insulation capability, the high-quality surface anticorrosion of component is handled, and the rubber cap of air vent design, prevent that effectively foreign matters such as dust, foreign material, water from entering valve inner, make product have waterproof and dustproof, antirust function, and operating current is little, low in energy consumption, big (voltage rating is DC24V, allows wave range 20V～30V) to the Applicable scope of voltage.The big latus rectum design of air valve simultaneously, specification is many, and applicability is good, can directly substitute the composite control of solenoid directional control valve and relay valve, has saved the space, has reduced the pipeline connection, has reduced the hidden danger of gas leakage, thereby has overcome above-mentioned deficiency.
Adopted DCF-A series low temperature normal off solenoid directional control valve, make that brake and drive system for vehicle with tow and tire fill, blow-off system simple to operation, the air valve latus rectum is big, specification is many, applicability is good, can directly substitute the composite control of solenoid directional control valve and relay valve.
Adopted flexible sealing structure, make between the solenoid valve inlet, outlet by the reliability height, low temperature resistant, broad application temperature range has reduced the difficulty of processing and the cost of spool, long service life, vehicle driving is safer.
Adopted on the base design of two mounting holes and air inlet intercommunicating pore, can realize that a plurality of solenoid valves combinations install and use, and only need connect air inlet pipeline just can proper functioning, be very easy to the user.
Adopt the rubber cap design of air vent, prevented that effectively foreign matters such as dust, foreign material, water from entering valve inner, effectively improved waterproof and dustproof, antirust ability.
