Abstract
The invention discloses a throttle valve structure, which comprises a valve body (1). A central hole of the valve body (1) consists of an inlet cone section (1a), a transition section (1b) and an outlet cone section (1c), wherein the transition section (1b) is a unidiameter straight section and is positioned between the inlet cone section (1a) and the outlet cone section (1c); the inlet cone section (1a) and the outlet cone section (1c) both have a bell-mouth structure; the length of the inlet cone section (1a) is between 11 and 17 millimeters, and the conical degree is between 5 and 8 degrees; and the length of the outlet cone section (1c) is between 17 and 23 millimeters, and the taper is between 3 and 6 degrees. The throttle valve structure meets the requirements of the air inlet speed and air inflow of small-displacement engines by changing a structure of the central hole of the valve body, and has the characteristics of ingenious design, simple structure, easy machining, strong generality and the like.
Description
Technical field
The invention belongs to technical field of motorcycles, specifically, the particularly electrospray throttle valve body on the motorcycle.
Background technique
The electrospray throttle valve body is the critical component of motorcycle electric control fuel oil jet system; Be connected between sky filter and the engine air inlet tube; Effect is the rotation angle through the closure valve block, controls the air inflow of motor, and the angle position signal of throttle plate pin is fed back to ECU.At present; Throttle body commonly used be through its center hole as air-flow path to the motor air feed, the internal diameter of this air-flow path is big, and almost is isometrical; Though air inflow is big; But it is slower that air communication is crossed the speed of throttle body, can only be applicable to large-duty engines such as 250ml, 400ml, can't satisfy the performance requirement of small displacement engine.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of electrospray throttle valve body structure, to satisfy the air inlet requirement of small displacement engine.
Technological scheme of the present invention is following: a kind of throttle valve structure, have valve body, and its key is: the center hole of said valve body is by cone section, changeover portion and go out the prostomum section and form; Wherein changeover portion is isodiametric straight section; And in the cone section and go out between the prostomum section, said cone section with go out the prostomum section and be the horn mouth structure, and smaller diameter end is connected with changeover portion; Wherein the length of cone section is 11～17mm; Tapering is 5～8 °, and the length that goes out the prostomum section is 17～23mm, and tapering is 3～6 °.
The present invention makes the internal diameter of throttle body valve body into two and is horn mouth, middlely is isometrical section; And pass through accurate Calculation; Optimize parameters such as two bell-mouthed length, tapering; When the air-flow that motor flows is getting into and flowing out valve body, can strengthen flow velocity through throttle body from empty filter like this, satisfy the requirement of the quick air inlets of small displacement engine such as 175ml, 200ml, guarantee to the air inflow of motor supply sufficient simultaneously.In addition, the horn mouth tapering at valve body center hole two ends is bigger, helps withdrawing pattern, can make things convenient for processing and fabricating.
As preferably, the length of said cone section is 14mm, and tapering is 6 °, and the length that goes out the prostomum section is 20mm, and tapering is 4 °; The internal diameter of said changeover portion is 30mm.
Beneficial effect: the present invention has satisfied the intake velocity and the air inflow requirement of small displacement engine through changing the structure of valve body center hole, has characteristics such as design is ingenious, simple in structure, easy processing, highly versatile.
Description of drawings

Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Like Fig. 1, shown in Figure 2; The center hole of electrospray throttle valve body valve body 1 is an air-flow path, and this center hole is by cone section 1a, changeover portion 1b and go out prostomum section 1c and form, and wherein changeover portion 1b is at cone section 1a and go out between the prostomum section 1c; Changeover portion 1b is isodiametric straight section, and internal diameter is 30mm.Said cone section 1a is connected with empty filter, and this cone section 1a is the horn mouth structure, and little head end links to each other with changeover portion 1b.The length of said cone section 1a is 11～17mm, is preferably 14mm in the present embodiment; The tapering of relative valve body 1 axis of cone section 1a is 5～8 °, is preferably 6 ° in the present embodiment.Saidly go out prostomum section 1c and be connected with engine air inlet tube, this goes out prostomum section 1c and also is the horn mouth structure, and little head end links to each other with changeover portion 1b.The said length that goes out prostomum section 1c is 17～23mm, is preferably 20mm in the present embodiment; The tapering that goes out prostomum section 1c is 3～6 °, is preferably 4 ° in the present embodiment.All the other structures of the present invention are identical with existing technology, do not do at this and give unnecessary details.
Claims (3)
1. an electric injection gas saving valve for motorcycle structure has valve body (1), it is characterized in that: the center hole of said valve body (1) is by cone section (1a), changeover portion (1b) and go out prostomum section (1c) and form; Wherein changeover portion (1b) is isodiametric straight section; And be positioned at cone section (1a) and go out between the prostomum section (1c), said cone section (1a) and go out prostomum section (1c) and be the horn mouth structure, and smaller diameter end is connected with changeover portion (1b); Wherein the length of cone section (1a) is 11～17mm; Tapering is 5～8 °, and the length that goes out prostomum section (1c) is 17～23mm, and tapering is 3～6 °.
