Abstract
The utility model relates to a throttle valve with an idling speed actuator. The throttle valve comprises a throttle valve body, a throttle valve shaft and a throttle valve piece. The throttle valve shaft and the throttle valve body are connected through a bearing. The throttle valve piece is installed on the throttle valve shaft. A sealing frame is fixed to the throttle valve body. A partition plate is arranged in the middle of the sealing frame. A regulating hole is formed in the middle of the partition plate. The idling speed actuator is fixed to the sealing frame. A cone valve of the idling speed actuator is matched with the regulating hole. The partition plate is used for dividing the sealing frame into an air inlet cavity and an air outlet cavity. An air inlet and an air outlet are formed in the throttle valve body. The air inlet is communicated with the air inlet cavity. The air outlet is communicated with the air outlet cavity. Air flow enters the air inlet cavity from the air inlet and flows out of the air outlet through the regulating hole to form a bypass air passage. Compared with the prior art, the throttle valve has the advantages of simplifying the technology and being easy to manufacture, compact in structure, small in size, high in reliability and the like.

Patent publication No. is that the patent of invention of CN103256123A discloses a kind of throttle body, comprise throttle body body, throttle plate pin, throttle blade, throttle position sensor, closure swing frame, torsion spring, drag-line and cable support, this invention is simple in structure, throttle blade and throttle body inner chamber are difficult for stuck, throttle body body adopts split type, its surface of internal cavity is provided with curved surface, can an injection molded, and low cost of manufacture.But, on this throttle body body, installation idle speed executor is not set, if will increase idle speed executor, can only be arranged on other positions, then by tracheae of extra increase or similar structure, air-flow is drawn, operation will cause volume to increase like this, complex structure.
Model utility content
The purpose of this utility model is exactly to provide a kind of throttle body with idle speed executor in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of throttle body with idle speed executor, comprise throttle body body, throttle plate pin and throttle blade, described throttle plate pin is connected by bearing with throttle body body, throttle blade is arranged on throttle plate pin, it is characterized in that, on throttle body body, be fixed with sealing frame, in the middle of described sealing frame, be provided with dividing plate, in the middle of described dividing plate, be provided with adjustment hole, described idle speed executor is fixed on sealing frame, the cone valve of described idle speed executor matches with adjustment hole, sealing frame is divided into air-inlet cavity and outlet chamber by described dividing plate, described throttle body body is provided with inlet hole and air outlet hole, described inlet hole is connected with air-inlet cavity, described air outlet hole is connected with outlet chamber, air-flow enters air-inlet cavity from inlet hole, flow out from air outlet hole again through adjustment hole, form bypass air flue.
Described throttle body body is linked into an integrated entity by closure upper semi-body and closure lower semi-body, described sealing frame is fixed on closure upper semi-body or closure lower semi-body, and described closure upper semi-body or closure lower semi-body are provided with and the inlet hole and the air outlet hole that seal frame and be communicated with.
The cone valve of described idle speed executor to stretch out direction consistent with charge air flow direction or contrary.
Compared with prior art, the utlity model has following advantage:
1, work simplification: throttle body body adopts split type, and inlet hole and air outlet hole direction are consistent with matched moulds direction, are easy to injection moulding manufacture;
2, compact structure: idle speed executor is directly installed on throttle body, and volume is little, simple in structure;
3, reliability is high: adjustment hole has certain height, if inlet hole has distilled water or dust etc. to enter, can be in sealing frame bottom deposition, and do not affect coordinating of cone valve and adjustment hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to cross-sectional schematic;
Fig. 3 is the partial enlarged drawing at B place in Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.Below introducing is only to illustrate of the present utility model, but not restriction to the utility model and application or purposes.Other mode of execution drawing according to the utility model, belongs to technological innovation scope of the present utility model too.
As Figure 1-3, a kind of throttle body with idle speed executor, comprise throttle body body 11, throttle plate pin 12, throttle blade 13, throttle position sensor 14, closure swing frame 15, torsion spring 16, drag-line 17 and cable support 18, throttle plate pin 12 is connected by bearing with throttle body body 11, throttle blade 13 is connected by two screws with throttle plate pin 12, closure swing frame 15 is enclosed within on throttle plate pin 12, be pressed on the throttle plate pin shaft shoulder and fixing axial position by nut and packing ring, one end of torsion spring 16 is hooked on throttle body body 11, the other end is connected with closure swing frame 15, cable support 18 is fixed by screws on throttle body body 11, throttle position sensor 14 is enclosed within on throttle plate pin 12 and by two screws and is fixed on throttle body body 11, drag-line 17 connects together with cable support 18, drag-line 17 is connected to again on closure swing frame 15, the angle of swing of throttle plate pin 12 is controlled in 15 rotations of closure swing frame, throttle blade 13 hard-overs are 90 degree, it is characterized in that, described throttle body body 11 is linked into an integrated entity by closure upper semi-body 111 and closure lower semi-body 112, on closure upper semi-body 111, be fixed with sealing frame 2, in the middle of described sealing frame 2, be provided with dividing plate 3, in the middle of described dividing plate 3, be provided with adjustment hole 4, described idle speed executor l is fixed on sealing frame 2, the cone valve 5 of described idle speed executor matches with adjustment hole 4, sealing frame 2 is divided into air-inlet cavity 2l and outlet chamber 22 by described dividing plate 3, described closure upper semi-body 111 is provided with inlet hole 113 and air outlet hole 114, described inlet hole 113 is connected with air-inlet cavity 2l, described air outlet hole 114 is connected with outlet chamber 22, air-flow enters air-inlet cavity 2l from inlet hole 113, flow out from air outlet hole 114 again through adjustment hole 4, form bypass air flue.
The utility model is mainly used for controlling the air mass flow of inflow engine, and the position feedback of throttle blade is provided simultaneously, and idle speed executor is used for controlling the flow of bypass air flue.Pull drag-line, drag-line and cable support connect together, drag-line is connected to again on closure swing frame, closure swing frame rotarily drives throttle plate pin rotation, throttle blade is arranged on throttle plate pin, the aperture size of directly having controlled throttle blade, throttle position sensor is used for detecting the aperture of closure.Idle speed executor stretch out (approaching adjustment hole direction) by cone valve and retract (away from adjustment hole direction) thus regulate the gap length control of cone valve and adjustment hole to flow through the air mass flow of adjustment hole.Air-flow enters air-inlet cavity by inlet hole, in the time that cone valve stretches out, and the gap smaller of adjustment hole and cone valve, the flow from air-inlet cavity to outlet chamber reduces; In the time that cone valve is retracted, it is large that the gap of adjustment hole and cone valve becomes, and the flow from air-inlet cavity to outlet chamber increases, and air-flow flows out through air outlet hole from outlet chamber afterwards, controls with this flow that enters bypass air flue.
