Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1 and Fig. 2, a kind of environment friendly motorcycle, comprise cylinder head of motorcycle, cylinder head of motorcycle comprises aluminum alloy cylinder head body, cylinder head body is provided with secondary air inlet valve base, secondary air inlet valve base and cylinder head body are structure as a whole, and make the installation on the engine of secondary air inlet control valve and associated pipe fixing very simple; In secondary air inlet valve base, there is secondary-air passage, secondary air inlet control valve and unidirectional stop valve is provided with in secondary-air passage, air outlet is communicated with engine cylinder head by steam outlet pipe, and the setting of unidirectional stop valve can prevent the waste gas of cylinder head relief opening from flowing backwards under exhaust pressure at short notice and enter secondary-air passage.
Described secondary air inlet control valve comprises control valve valve body, and described control valve valve body comprises upper cover body and lower cover; The upper part of the inwall of described upper cover body and secondary-air passage seat forms negative cavity, upper cover body has the negative pressure mouth be communicated with its negative cavity, the lower part of the inwall of described lower cover and secondary-air passage forms air-inlet cavity, lower cover has the air inlet be communicated with air-inlet cavity; Be provided with control valve valve rod in described control valve valve body, in negative cavity, be provided with coaxial diaphragm fixed plate from top to down, rubber valve diaphragm and control valve diaphragm; Air-inlet cavity is provided with coaxial lower card, control valve valve block, upper clamp slice and spring seat from below to up; Described diaphragm fixed plate, rubber valve diaphragm and control valve diaphragm are arranged on the top of control valve valve rod from top to down successively, described lower card, control valve valve block, upper clamp slice and spring seat are arranged on the lower end of control valve valve rod from below to up successively, and the control valve valve rod between spring seat and control valve diaphragm is provided with control valve spring.
Described unidirectional stop valve comprises stop valve body and mangetic core assembly, mangetic core assembly comprises the valve head of stop valve valve rod and taper, one end that valve head diameter is large is fixedly connected with one end of stop valve valve rod, stop valve body is connected with valve body stopper near the side of stop valve valve rod, valve body stopper and stop valve body have coaxial axis hole, stop valve valve rod and axis hole Spielpassung; Stop valve valve rod between valve body stopper and valve head is provided with stop valve stage clip, and the external diameter of stop valve stage clip is less than the diameter of axis hole; Unidirectional stop valve also comprises the upper casing being positioned at the little one end of valve head diameter, upper casing has center hole vertically, the end face diameter of one end that valve head diameter is large is less than the internal diameter of upper casing, inner seal ring is provided with in upper casing, upper casing outer surface circumference has draw-in groove, be connected with exterior seal ring in draw-in groove, the external diameter of exterior seal ring is greater than the external diameter of upper casing.
Described valve body is taper in the position of valve body stopper, and the outer circumferential face of this conical section is provided with four outstanding blocking blades, and these blocking blades are arranged along the radial position of stop valve body, and they are distributed on the outer circumferential face of stop valve body.
During use, this unidirectional stop valve is arranged in secondary-air passage, stop valve body and upper casing are fixed relative to secondary-air passage inwall, when gas comes from stop valve body direction, gas pressure makes the inner seal ring in valve head and upper casing compress, thus gas cannot be passed from the center hole of upper casing, again due to the seal action of exterior seal ring, make to seal between upper casing and secondary-air passage inwall, thus gas also cannot pass between upper casing and secondary-air passage inwall, achieve the unidirectional cutoff that gas is current.When gas flow stop valve body direction, stop valve stage clip withstands on valve body stopper place, gas pressure makes it compress generation deformation, valve head and inner seal ring are thrown off, gas enters from center hole, again because the through hole on stop valve valve rod and stop valve body is Spielpassung, therefore, gas flows out from the gap between stop valve body and through hole.
