Description
Technical field
The utility model relates to a kind of carburetor for motorcycle.
Background technique
Carburetor for motorcycle allows air and the well-mixed device of oil gas, in prior art, it is one section of venturi conduit normally, in pipe, the power adjusting needle of working in coordination and metering rod jet are set, power adjusting needle promotes to plug together with metering rod jet thus to be blocked by pipeline by piston, and metering rod jet is communicated with fuel reserve tank away from power adjusting needle one end, and oil gas enters into venturi conduit by metering rod jet, air then enters from venturi conduit one end, thus realizes mixing.But because power adjusting needle is frequent and metering rod jet friction, metering rod jet and power adjusting needle contact-segment are easy to wear and tear.
Model utility content
Main purpose of the present utility model is to provide one and is easy to maintenance, the carburetor for motorcycle of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of carburetor for motorcycle, comprise axial level and the gas flow of intermediate section reduced cross-sectional area, perforate above gas flow, arranging in this hole can at the piston of vertical direction motion, piston arranges the power adjusting needle of adjusting gas flow, power adjusting needle axially vertically and small end down, the position corresponding to power adjusting needle below gas flow is provided with metering rod jet, the small end of described power adjusting needle can move up and down in metering rod jet inside, the lower end of metering rod jet is communicated with fuel reserve tank, described metering rod jet is threaded with gas flow with power adjusting needle contact-segment, and this section of material is Wear-resistant, high-temperature resistant material.
That is, metering rod jet is divided into two sections, be Wear-resistant, high-temperature resistant material in the position often touched with power adjusting needle, and this section can be back-outed from gas flow inwall by rotating screw thread, like this, the performance enhancement of this section of metering rod jet Wear-resistant, high-temperature resistant, and if its wear and tear, then back-out by rotation screw thread and change, the working life of whole Carburetor is increased.
Further, described Wear-resistant, high-temperature resistant material is metallic copper.
Further, the described metering rod jet section lower ending opening be threaded with gas flow is less than upper end open.That is little greatly upper under this section of metering rod jet be threaded, like this, lower end produces barrier effect to the passage of oil gas, makes this place's oil gas and air mixture that turbulent flow occur, thus strengthens its gas and vapor permeation effect.
Further, described power adjusting needle needle-like position is conical, and the shape of the metering rod jet sector hole be threaded with gas flow is circular cone stage body, and the tapering of this circular cone stage body is identical with the tapering at the needle-like position of power adjusting needle.So no matter how needle-valve rotates, can ensure metering rod jet and its can well fit.
A kind of easy to wear section of carburetor for motorcycle metering rod jet of the utility model adopts thread connecting mode to be connected with Carburetor, only needing to be back-outed to change, greatly increasing the working life of whole Carburetor when maintaining.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of carburetor for motorcycle of the utility model.
Embodiment
Be described as follows with reference to Fig. 1: the air flow channel of axial level is the Venturi tube of middle shrinkage, perforate above it, the piston 7 that can move up and down is set in hole, described perforate upper end arranges top cover 1, arrange jump ring 12 between top cover 1 and piston 7, jump ring 12 one end contacts with top cover 1, and the other end connects power adjusting needle 4, the small end of described power adjusting needle 4 and pointed end, power adjusting needle 4 upper end is fixed on piston 7.The gas flow 2 lower wall place most advanced and sophisticated corresponding with power adjusting needle 4 arranges the metering rod jet 6 that can engage with power adjusting needle 4, and metering rod jet 6 is communicated with fuel reserve tank 5 away from the one end open of power adjusting needle 4, and gas flow 2 arranges closure 3 away from chock plate 10 end.Arrange the float 8 for responding to oil level in fuel reserve tank 5, float 8 is hinged with the float articulated column 9 be arranged in fuel reserve tank 5, and hinging shaft arranges needle-valve, and needle-valve can control the opening and closing for the oil pipe 11 to transferring oil in fuel reserve tank 5.Oil level rises to a certain degree, and the needle-valve on hinging shaft then upwards ejects closed oil pipe 11.Described metering rod jet 6 is threaded with gas flow 2 with power adjusting needle 4 contact-segment, and this section of material is metallic copper material.Described power adjusting needle 4 needle-like position is lower large little taper shape, the shape of metering rod jet 6 sector hole be threaded with gas flow 2 is circular cone stage body, and the tapering of this circular cone stage body is identical with the tapering at the needle-like position of power adjusting needle 4, namely metering rod jet 6 and power adjusting needle 4 can seamlessly close.
Air enters from gas flow 2 left end opening, regulates the chock plate 10 of air input when this end being provided with is mainly used in motorcycle initiating.After air enters gas flow 2, after power adjusting needle 4 stops, enter gas flow 2 right-hand member, the negative pressure that oil gas produces due to the contraction of gas flow 2 is mixed into gas flow 2 right-hand member by sucking-off and air from metering rod jet 6.
