Description
Technical field
The utility model relates to a kind of two two logical high-speed switch valves, belongs to gas high-speed electromagnetic valve technical field.
Background technique
The supporting pneumatic machinery automatic transmission (AMT) of commercial car can make automobile obtain optimal fuel economy, power character and low exhaust gas emission, alleviates driving fatigue, improves driving safety, and its Clutch Control adopts the gas high-speed electromagnetic valve to control.
Under common not gear shift of the automobile situation, inlet high-speed electromagnetic valve and the equal no electric circuit of outlet high-speed electromagnetic valve, promptly high-speed electromagnetic valve keeps closed condition, and cylinder keeps clutch under the effect of spring.During gear shift, the energising of inlet high-speed electromagnetic valve is opened, and cylinder communicates with source of the gas, and pressure increases, and overcomes the cylinder spring force and makes clutch separation.After the gear shift, the outage of inlet high-speed electromagnetic valve is closed, and cylinder and source of the gas disconnect, and the energising of outlet high-speed electromagnetic valve is opened, and cylinder communicates with atmosphere, removal pressure, and the cylinder spring promotes piston reset, makes clutch.The outage of outlet high-speed electromagnetic valve is closed.
In order to guarantee that gear shift steadily needs control with the speed of separating clutch, promptly speed will be as quickly as possible during clutch separation, and at first want fast moving during clutch, and is slowly approaching then, engages fast again.
The quick separation of clutch can realize by the switch of high-speed electromagnetic valve, and the fast more first quick and back slow engaging process of clutch must be realized by the exhaust velocity of control cylinder.The inlet high-speed electromagnetic valve of the method control by pulsewidth modulation and outlet high-speed electromagnetic valve are realized the adjusting of the exhaust velocity of cylinder, i.e. exhaust velocity of recently regulating cylinder by the duty of control pulse-width signal.
The existing industrial pneumatic control Proportional valve of Cai Yonging, although scheme is feasible, this product is not the automobile product, does not satisfy the automobilism environmental requirement, and costs an arm and a leg.Carried out invention of the present utility model for this reason.
Summary of the invention
Cost an arm and a leg, can't satisfy the technical problem that running environment requires in order to solve existing automobile with the pneumatic control Proportional valve, it is a kind of reasonable in design that the utility model provides, and compact structure is fit to batch product, safe and reliable normal close type gas high-speed electromagnetic valve.
Technical solution of the present utility model:
A kind of two two logical high-speed switch valves comprise electromagnet assembly and valve component, and its special way is:
Described valve component comprises valve seat 7, is arranged on the sleeve 4 and the spring 6 in valve seat 7 outsides;
Described electromagnet assembly comprises shell 2, be arranged on coil 3 in the shell 2, be arranged on coil 3 centers buting iron 1, be arranged on the armature component 5 in the sleeve 4;
Described valve seat 7 is a nonmetal structure;
Described sleeve 4 is for encasing the plastic deformation closing in metallic case of valve seat 7, and the upper end of described sleeve 4 and buting iron 1 are connected;
The upper end of described armature component 5 is an armature 51, and the lower end of described armature component 5 is a spool 52; Described armature 51 can axially be free to slide in sleeve 4, and described spool 52 constitutes sealing configuration with valve seat 7;
The upper end of described spring 6 withstands on sleeve 4 inwalls, and the lower end of described spring 6 withstands on the spool 52.
The advantage that the utility model had:
1, valve seat 7 adopts the plasticity closing in to be connected with sleeve 4 one ends, and it is simple to have form, is easy to realize the characteristics of mass.
2, buting iron 1 adopts with sleeve 4 one ends and is welded to connect, and has the structural feature of not leaking, and has reduced the complexity of structure.
3, valve seat adopts the amount of deformation of rubber on the nonmetal spacing restriction armature, guarantees the life-span of sealing configuration, but valve seat adopts the nonmetallic material of injection moulding, is fit to produce in batches.
4, two two logical high-speed switch valve fast response characteristics of the present utility model: this solenoid valve reaches 5ms with interior response characteristic, can realize the pulsewidth modulation mode of operation of 50Hz.
5, two the two logical high-speed switch valve long-life of the present utility model: solenoid valve can move 8 * 107 times, and guarantees the effective sealing to gas medium, is fit to produce in batches: the processing technology of part and assembly technology adapt to be produced in batches.
Description of drawings
Fig. 1 is the structural representation of two two logical high-speed switch valves of the utility model;
Reference character wherein: 1-buting iron, 2-shell, 3-magnetic coil, 4-sleeve, 5-armature component, 51-armature, 52-spool, 6-spring, 7-valve seat, 8-O shape rubber ring.
Embodiment
The present utility model mainly partly is made up of valve portion and electromagnet, and valve portion mainly comprises sleeve 4, spring 6, and valve seat 7, and O shape rubber ring 8, the electromagnet part mainly comprises buting iron 1, shell 2, coil 3, armature component 5.The electromagnetic attraction that electromagnet partly produces is applied on the armature of armature component 5.Buting iron 1 adopts with sleeve 4 one ends and is welded to connect, and has the structural feature of not leaking, and has reduced the complexity of structure.Valve seat 7 adopts the plasticity closing in to be connected with sleeve 4 one ends, and it is simple to have form, is easy to realize the characteristics of mass.
Working principle of the present utility model: an end inserts sleeve and can produce the buting iron of electromagnetic attraction vertically upward under electromagnetic field effect, effective shell that connects buting iron and armature magnetic circuit and form closed magnetic path, the coil that can generate an electromagnetic field after the energising, pass the coil intermediate portion and with buting iron, armature component and valve seat effectively connect the all-in-one-piece cylindrical sleeve, under electromagnetic field effect, can produce the armature component of electromagnetic attraction vertically upward, act on the armature component and when the coil no electric circuit, make the spool of armature component be fitted in spring on the valve seat, be provided with the valve seat of gas channel and interface, when coil electricity, make buting iron and armature keep the rubber o-ring of certain air gap.Valve seat adopts the rubber deformation amount on the spool of nonmetal spacing restriction armature component, guarantees the life-span of sealing configuration, but valve seat adopts the nonmetallic material of injection moulding, is fit to produce in batches.
After the solenoid valve energising, armature component 5 overcomes spring force, air pressure unbalanced force, frictional force under the electromagnetic attraction effect, make spool lift off a seat 7, and solenoid valve is opened; After the solenoid valve outage, electromagnetic attraction disappears, and armature component 5 overcomes remanent magnetism suction and frictional force under the effect of spring force and air pressure unbalanced force, make spool get back on the valve seat 7 closed electromagnetic valve.
