Description
Technical field
The present invention relates to a kind of technical field of electrically controlled gas supplementing device of motor vehicle engine, refer in particular to a kind of structure indoor outer application, that employing is new and air-flow control electromagnetic valve of Placement of being suitable for.
Background technique
In the electric controlled energy saving cleaning plant (or claiming the electronics making-up air device) of automobile and motorcycle, solenoid valve is the power unit of core, controller ECU in this control gear is respectively to solenoid valve main valve and pair valve output control signal, control electromagnetic valve is opened, the dutycycle of shut-in time, realize entering replenishing and regulation and control of engine air capacity by the solenoid valve main valve thus, also claim aeration valve one time, pay valve to carrying out secondary air compensating between engine exhaust port and the catalytic converter by solenoid valve, also claim secondary air-supplementing valve, the concentration that is to say the mixed gas that automobile or motorcycle are provided is controlled, make motor realize good burning, make the higher efficient work of catalytic converter that is installed in outlet pipe, thereby effectively reduce oil consumption and reduce noxious emission, the working principle block diagram of electric controlled energy saving clarification system (can reach Europe three above emission standards) among visible accompanying drawing 23 the present invention.Because control gear sends the control command of open and close duty ratio of time to solenoid valve, thereby requires solenoid valve that very high frequency of okperation and speed of response will be arranged along with the operation of motor changes in good time, require lower operational noise again.And at present, the structure and the Placement of the solenoid valve inside of the former preparation of this control gear, for this product how to be convenient to mass production, further to improve aspect such as reliability desirable not enough, and it needs corresponding the connection and fastening accessory when producing assembling, has increased installation and manufacture cost.In addition, its sealing structure of existing solenoid valve is relatively poor, can't carry out moistureproof and waterproof well.
Summary of the invention
Purpose of the present invention is exactly to provide the new structure and the air-flow control electromagnetic valve of Placement at existing air-flow control electromagnetic valve above shortcomings part, a kind of extremely is convenient to install, highly sensitive fast with speed of response, can reduce the discharging of harmful gas and material, save fuel oil, good seal performance, reliability height, and have the moistureproof and waterproof effect, there is not the air-flow control electromagnetic valve of general connection and secure component.
For achieving the above object, the present invention includes the valve seat and the electromagnetic actuator device that have suction port and air outlet, described electromagnetic actuator device comprises: a soft iron external member, and it is made of the U-shaped framework and the sealing baffle that form closed magnetic loop, perhaps only is made of a U-shaped framework; Some groups of drive wire bags, it is connected with signal input line and is wrapped in the coil frame outside, and is built in the chamber between soft iron external member and the coil frame; One coil frame, it is hollow structure, plugs in the U-shaped deckle board that is fixed in the soft iron external member; One fixed core, it plugs an end that is fixed on coil frame hollow cavity axle center; One moving iron core, its end towards valve seat is connected with seal ring, and it is inserted in the other end in coil frame hollow cavity axle center; Between the moving iron core of two adjacent surfaces and fixed core, Returnning spring is housed; One soft iron external member and drive wire bag and moving iron core, fixed core is built in the plastic shell.The plastic shell of solenoid valve is by the mode of ultrasonic welding or molding and forming, plastic shell respectively and valve seat, fixed core is fastenedly connected, and finishes the last encapsulation of solenoid valve simultaneously.
After adopting said structure and Placement, the present invention has the following advantages: owing to do not have general connection and secure component, significantly reduced the product assembling, manufacture cost, and good sealing and moistureproof effect have been reached, guaranteed like this solenoid valve can be under abominable external environment condition and weather conditions proper functioning, effectively improved product and device reliability of operation.
Adopt the moving iron core of bullet type and the fixed core of anti-truncated cone shape, and Returnning spring and rubber buffer ring be set between moving iron core and fixed core, and technical measures such as the line bag of particular design and coil frame, make its driving force, working sensitivity, speed of response and durability, reliability improves, noise lowers greatly, fuel-economizing and discharging all are significantly improved, reduce cost effectively simultaneously, be convenient to the extensive operation of new product, the fuel saving ratio of automobile and motorcycle all can reach more than 5% after tested, and discharging all can reach No. three standards of No. two standards in Europe and Europe.
Electric controlled energy saving cleaning system dress (or claiming electronics tonifying Qi dress ) for motor vehicle, the solenoid valve main valve i.e. an aeration valve, paying valve with solenoid valve is that the main distinction of secondary air-supplementing valve is: aeration valve adopt usually be provided with one air outlet promptly steam outlet pipe, be provided with the valve seat of a suction tude in addition, secondary air-supplementing valve adopt usually be provided with one air outlet promptly steam outlet pipe, be provided with the valve seat of several suction ports in addition.These two classes air-flow other structures of control electromagnetic valve and Placement are basic identical.And the structure of the valve seat of an aeration valve has two big classes usually: a kind of is the basic vertical distribution of suction tude and steam outlet pipe, another kind is the substantially parallel distribution of suction tude and steam outlet pipe, can go according to client's different needs to select, two kinds of valve seat constructions are such as accompanying drawing 20,21 shown in.And need to install porous sponge or other air-filtering layers in several suction ports of secondary air compensating valve base, with impurity in the filtered air and reduction noise, as shown in Figure 22.
