For solving the problem, the utility model provides a kind of adjustable motorcycle secondary suction valve, described adjustable motorcycle secondary suction valve comprises air inlet end cap, housing, spool, Returnning spring, screw rod and stepper motor, described housing and described air inlet end cap are fixed, described stepper motor is fixed in described housing, and be positioned at housing one end away from described air inlet end cap, described spool is arranged on described screw rod, the output shaft of described screw rod and described stepper motor is fixed, described Returnning spring and described screw coaxial are arranged, and one end of described Returnning spring and described stepper motor inconsistent, the other end and the spool of described Returnning spring are inconsistent, and described spool and described air inlet end cap inconsistent.
Further, described inlet end covers and is provided with gas-entered passageway and outlet passageway, and described gas-entered passageway is communicated with described outlet passageway, and one end that described air inlet end cap is connected with described housing is provided with internal thread, described air inlet end cap Vertical direction extends mounting blocks, and described mounting blocks is provided with mounting hole.
Further, described spool comprises rubber stopper and connecting body, and described rubber stopper is fixed on one end of connecting body, and the other end of described connecting body is connected with described screw rod.
Further, described connecting body is provided with receiving cavity, and one end that described connecting body is connected with described screw rod is provided with internal thread.
Further, one end that described housing is connected with described air inlet end cap is provided with outside thread.
The adjustable motorcycle secondary suction valve of the utility model carrys out moving valve core by stepper motor, secondary air inlet valve can be opened during stepper motor energising, and the size of valve open is adjusted by the corner adjusting stepper motor, under the effect of Returnning spring, secondary air inlet valve is closed during power-off, switch, close reliable, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of the adjustable motorcycle secondary suction valve of the utility model.
Fig. 2 is the internal structure schematic diagram of adjustable motorcycle secondary suction valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the better embodiment of the adjustable motorcycle secondary suction valve of the utility model comprises air inlet end cap 1, housing 2, spool 3, Returnning spring 4, screw rod 6 and stepper motor 5, one end of described air inlet end cap 1 and one end of described housing 2 are fixed, described stepper motor 5 is fixed in described housing 2, and be positioned at the other end of described housing 2, be namely positioned at housing 2 one end away from described air inlet end cap 1; Described spool 3 is arranged on described screw rod 6, and described screw rod 6 is fixed by the output shaft of coupling and described stepper motor 5; Described Returnning spring 4 is coaxially arranged with described screw rod 6, in other words, the shaft axis of described Returnning spring 4 and the shaft axis of screw rod 6 are on the same line, one end and the described stepper motor 5 of described Returnning spring 4 are inconsistent, the other end and the spool 3 of described Returnning spring 4 are inconsistent, and described spool 3 is inconsistent with described air inlet end cap 1.
Described air inlet end cap 1 is provided with gas-entered passageway 11 and outlet passageway 12, and described gas-entered passageway 11 is communicated with described outlet passageway 12.One end that described air inlet end cap 1 is connected with described housing 2 is provided with internal thread, and described air inlet end cap 1 Vertical direction extends mounting blocks 13, and described mounting blocks 13 is provided with mounting hole, is convenient to adjustable motorcycle secondary suction valve to fix.One end that described housing 2 is connected with described air inlet end cap 1 is provided with outside thread.Housing 2 and air inlet end cap 1 are fixed by the mode of screw thread.
Described spool 3 comprises rubber stopper 31 and connecting body 32, described rubber stopper 31 is fixed on one end of connecting body 32, and the other end of described connecting body 32 is connected with described screw rod 6, specifically, described connecting body 32 is provided with receiving cavity, and one end that described connecting body 32 is connected with described screw rod 6 is provided with internal thread.
When stepper motor 5 is energized, stepper motor 5 drives screw rod 6 to rotate, and screw rod 6 is with movable valve plug 3 to move forward and backward, the distance of spool 3 movement is controlled by the corner of control step motor 5, realization like this is to the adjustment of air inflow size, and during valve open, Returnning spring 4 is in compressive state.When stepper motor 5 power-off, because Returnning spring 4 is in compressive state when stepper motor 5 is energized, therefore Returnning spring 4 can promote spool 3 and moves to the opposite direction of stepper motor 5, makes the rubber stopper 31 of its spool 3 block gas-entered passageway, throttle down like this.During use, only need the energising of control step motor 5, can open or close valve, the corner of control step motor 5 can realize the control to air inflow size, simple to operate, easy to use, and reliability is high.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
