Abstract
The invention provides a throttle valve which comprises a valve body, wherein a throttling bypass is arranged on the valve body and a division device is arranged in the throttling bypass. The throttle valve can balance action force of airflow on a splicing head of a stepping motor, thereby greatly improving the eccentric wear problem, enhancing the idle speed performance of a whole vehicle and prolonging the service life of the throttle valve.
Description
Technical field
The present invention relates to the closure technical field, particularly a kind of closure.
Background technique
Has only a suction port in the solar term by-pass of closure of the prior art, there is a significant deficiency in this structure, mainly be since during idling operation bypass flow idle speed step motor is pieced together head a monolateral stressed effect is arranged, thereby cause this solar term by-pass and stepper motor to piece together a cooperation place and produce eccentric wear, and then the validity of reduction air inflow, influence Motor Vehicle car load idling performance, cause idling operation defectives such as Motor Vehicle unstable idle speed, idling height, reduce the working life of closure.
Summary of the invention
The invention provides a kind of closure, with the active force of balance air-flow on stepper motor assembly head.
To achieve these goals, the invention provides following technological scheme:
A kind of closure comprises the valve body, and described valve body is provided with the solar term by-pass, and described solar term are provided with part flow arrangement in the by-pass.
Preferably, described part flow arrangement is the shunting cover.
Preferably, described shunting puts the tap hole that is provided with a shape of symmetry.
Preferably, described shunting cover is made by engineering plastics or is made by metallic material.
Preferably, described shunting cover becomes interference fit with the by-pass hole of solar term by-pass.
By implementing above technological scheme, have following technique effect: closure provided by the invention, with the active force of balance air-flow on stepper motor assembly head, improved the eccentric wear problem greatly; Promote the car load idling performance, promoted the working life of closure.
Description of drawings
The structural representation of the closure that Fig. 1 provides for the embodiment of the invention;
Fig. 2 is the D-D sectional view of Fig. 1;
The structural representation that Fig. 3 overlaps for the shunting that the embodiment of the invention provides.
Embodiment
Technological scheme is for a better understanding of the present invention described embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the invention provides a kind of closure, as Fig. 1, Fig. 2 and shown in Figure 3, comprises valve body 3, and described valve body 3 is provided with solar term by-pass 31, wherein, is provided with part flow arrangement in the described solar term by-pass 31.Preferably, as shown in Figures 2 and 3, described part flow arrangement is shunting cover 8.Described stepper motor is pieced together head and is arranged in described shunting cover, and described stepper motor is pieced together 71 and is arranged on the stepper motor 7.In other embodiments, this part flow arrangement also can be other the parts that are used to shunt.
The closure that the foregoing description provides, stepper motor is pieced together head in part flow arrangement (shunting cover) hollow gap motion during work.The inlet of air-flow from Fig. 1 enters solar term by-pass 31, flows out from outlet.Shunting cover is shunted air with the passage that the stepper motor hole forms, and is stressed thereby the balance stepper motor is pieced together, and avoids piecing together head because of stepper motor and is subjected to monolateral unbalanced force to cause throttle body body and stepper motor to piece together head to produce an eccentric wear, influence the car load idling performance.Described closure is working stability, reliable in quality under the car load working state; But operability, applicability generalization height.Solved and pieced together head because of stepper motor and be subjected to force unbalance to cause throttle body body and stepper motor to piece together head to produce an eccentric wear, and caused problems such as car load idling height, unstable idle speed, also promote simultaneously closure working life, reduced product cost.
In embodiment more specifically, the tap hole that is provided with a shape 81 of symmetry on the described shunting cover 8.
Preferably, described shunting cover 8 is made or is made by metallic material by engineering plastics.
Preferably, described shunting cover 8 becomes interference fit with the by-pass hole of solar term by-pass 31.The stepper motor hole that 8 interference of shunting cover are installed in stepper motor hole (solar term by-pass) and this tb forms runner, better plays shunting action.
More than a kind of closure that the embodiment of the invention provided is described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
