The multilayer-piezoelectric-ceramic idling air control valve is characterized in that an installation base is installed on a mechanical throttle body through a bolt and is sealed through a sealing rubber ring, air is prevented from leaking, one end of a multilayer-piezoelectric-ceramic crystal adheres to the installation base, the other end of the multilayer-piezoelectric-ceramic crystal is connected with a transmission shaft, an adjusting head is installed at the front end of the transmission shaft, and the outer diameter of the rear end of the adjusting head is larger than the diameter of an idling air inlet in the throttle body. According to the multilayer-piezoelectric-ceramic idling air control valve, a traditional stepping motor control valve is replaced, the control accuracy, the control frequency and the responding speed are greatly improved, energy consumption and noise are reduced, the size of the control valve is reduced, and the service life of the control valve is greatly prolonged.
Description
Technical field
The utility model relates to a kind of linear control valve, relates in particular to a kind of idle air control valve that adopts multilayer piezoelectric ceramic crystal-driven.
Background technique
Day by day serious along with pollution of atmosphere, being on the increase of haze weather, China is also increasingly strict to the policies and regulations of motor vehicle emission control, promoting China's vehicular emission control technique improves constantly, eliminate old Manufacturing Technology for Carburetors, develop new Electronic Fuel Injection (EFI) technology, and to constantly bring forth new ideas this technology advances be trend of the times.
Piezoelectric constant idle air control valve is to substitute the new generation product of common step motor type idle air control valve, has improved that its frequency of okperation is low, low-response, defect that control accuracy is low.Adopt the idle air control valve of multilayer piezoelectric ceramic idle air control valve as mechanical type air throttle body, its feature is that frequency of okperation is high, fast response time, control accuracy is high, the life-span is long, noise is low, energy consumption is low, volume is little etc., in meeting Motor Vehicle idle air control, also can participate in the inflammable mixture air-fuel ratio regulation of full operating conditions, the pollutant emission control during to Motor Vehicle idling and full operating mode operation has positive effect.
Model utility content
The purpose of this utility model is to provide a kind of multilayer piezoelectric ceramic idle air control valve, replace traditional step motor control valve, greatly improved control accuracy, control frequency, speed of response, reduced energy consumption and noise, dwindle control valve volume, and greatly extended the life-span of control valve.
The technical solution of the utility model is: a kind of multilayer piezoelectric ceramic idle air control valve, its feature mounting base is arranged on mechanical type air throttle body by bolt, realize sealing by O-ring seal, prevent air leak, multilayer piezoelectric ceramic crystal one end is bonded on mounting base, the other end is connected with transmission shaft, and adjusting head is arranged on the front end of transmission shaft, and the rear end external diameter of adjusting head is greater than the diameter of idling air inlet on throttle body.
Wherein each layer of ceramic plate Crystal polarization of multilayer piezoelectric ceramic crystal becomes two-part interdigital structure of opposed polarity, and the polarity of adjacent ceramic sheet piezoelectric crystal is contrary, driven and can be prolonged axial stretching by positive counter voltage, promotes adjusting head and opens or closes air passageways.
The utility model has been overturned traditional step motor type control valve, adopts multilayer piezoelectric ceramic crystal to replace stepper motor as driver part.Make that idle air control valve volume is less, energy consumption is lower, price is lower, noise is lower, corresponding faster, control frequency is higher, control accuracy is higher, the life-span is longer.The advantage that has more is installed on the throttle body of narrow space.

Embodiment
As shown in figures 1 and 3, the utility model multilayer piezoelectric ceramic idle air control valve, mounting base 7 is arranged on mechanical type air throttle body 4 by bolt 6, realizes sealing by O-ring seal 5, prevents air leak.Multilayer piezoelectric ceramic crystal 8 one end are bonded on mounting base 7, the other end is connected with transmission shaft 3, adjusting head 2 is arranged on the front end of transmission shaft 3, and the rear end external diameter of adjusting head 2 is greater than the diameter of idling air inlet 1 on throttle body, guarantees to close completely when needed idle speed air admission.Multilayer piezoelectric ceramic crystal 8 is at ECU(electronic control unit) control under elongate or shorten, thereby drive transmission shaft 3 and adjusting head 2 to move forward and backward, open or close idling air inlet 1, control fresh air and enter motor by idling air passageways 9.Meanwhile, due to the characteristic of multilayer piezoelectric ceramic crystal itself, air mass flow can be controlled by two kinds of modes.One is that multilayer piezoelectric ceramic crystal passes through vibration, and the time opening or closing with the form control of dutycycle is controlled air mass flow; Another kind is to change the voltage that imposes on multilayer piezoelectric ceramic crystal, can change the extending amount of multilayer piezoelectric ceramic crystal, the aperture that regulating and controlling head is opened, thus control air mass flow.These two kinds of control modes also can be used in combination, practical more flexibly.
As shown in Figure 2, each layer of ceramic plate Crystal polarization of multilayer piezoelectric ceramic crystal 8 becomes two-part interdigital structure of opposed polarity, and the polarity of adjacent ceramic sheet piezoelectric crystal is contrary.
In the time applying voltage to multilayer piezoelectric ceramic crystal 8, can control multilayer piezoelectric ceramic crystal 8 and elongate or shorten, drive adjusting head 2 to move forward and backward, open, close suction port 1, or the aperture of change suction port 1, thereby control the flow that enters motor by idling air passageways 9.Thereby can effectively regulate the air fuel ratio of the inflammable mixture that enters engine combustion.
