Abstract
The utility model discloses an adjustable float needle valve capable of matching with a motorcycle carburetor to be used, comprising a needle valve head, a needle valve tail, a bolt, a positioning locking nut, an inner nut and a cushion seal mat, wherein, the front end of the needle valve head presents tapered; the surface is glued with the cushion seal mat; the tail part is provided with the hollow cavity provided with screw threads which is the inner nut; the needle valve head and the needle valve tail are screwed into the inner nut through the bolt; the positioning locking nut is tightly fixed on the tight screwing position of the inner nut and the bolt and the needle valve tail and the bolt are designed into one integration. The utility model is simple in structure and convenient in adjustment.
Description
The utility model relates to a kind of adjustable float needle valve, belongs to the Component of motorcycle and other traffic tool, is and the matching used parts of engine and carburetor.
The adjustable pasta formula Carburetor that existing motorcycle uses, as Chongqing CY80 type, its regulative mode is the height that the height of adjusting metal hinge arm is regulated pasta, promptly be used to break off with the fingers and thumb tongue piece, when regulating repeatedly, can cause the fatigue of metal hinge tongue piece, very easily form the fracture of tongue of metal.And this Carburetor manufacturing process complexity has the metal hinge arm combines difficulty with nonmetal float problem.Also have a kind of can not the mode Carburetor, as " star's 50 types ", its pasta height can not be adjusted, mixed gas overrich when causing engine operation or rare excessively, the unusual direct proper functioning that influences motor of mixed gas directly influences the power of motor, moment of torsion, acceleration and Economy.And have a large amount of air-polluting waste gas to discharge, cause environmental pollution.
The purpose of this utility model is to provide a kind of preparation process adjustable float needle valve simple, pollution-free, easy to adjust in order to overcome above-mentioned the deficiencies in the prior art part.
The purpose of this utility model is achieved in that the utility model is made up of needle-valve head, needle-valve tail, screw rod, positioning and locking nut, inner nut, cushion seal pad, be pasted with the cushion seal pad on the front end surface of needle-valve head, the rear portion of needle-valve head is a screwed cavity, be that inner nut, needle-valve head and needle-valve tail screw in the inner nut with screw rod, the positioning and locking nut is fastened on screwing on the position of inner nut and screw rod.
The purpose of this utility model can also reach by following measure: needle-valve tail and screw design are one.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic representation that the utility model and Carburetor are used.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
Among Fig. 1, needle-valve head (1), needle-valve tail (2), screw rod (3), positioning and locking nut (4), inner nut (5), cushion seal pad (6).
Among Fig. 2, oil intake nozzle (7), float supporting frame (8), float arm axle (9), float arm (10), float chamber (11), fuel oil face (12), float (13).
The front end of needle-valve head (1) is tapered, tapered paste outside one deck cushion seal pad (6), 2/3 place, rear portion of needle-valve head (1) is a screwed cavity, cavity is inner nut (5), needle-valve tail (2) is an one with screw rod (3), needle-valve head (1) is used in screw rod (3) the precession inner nut (5) with needle-valve tail (2), and is fixed with locking nut (4).The length that screws in the inner nut (5) by adjusting screw rod (3) also reaches the total length that elongates or shortens float needle valve with the positioning and locking of positioning and locking nut (4), in order to the height of regulating and controlling float chamber pasta, and then reach the concentration that adjusting enters mixed gas in the engine chamber.
Working procedure of the present utility model is: fuel oil enters float chamber (11) through oil intake nozzle (7) and adjustable float needle valve head (1), when pasta rises to certain altitude, float (13) is subjected to buoyancy function with float arm (10), with the float arm axle (9) on the float supporting frame (8) is the center, drive adjustable float needle valve rising and close oil intake nozzle (1), stop fuel oil and enter float chamber.Liquid level in the float chamber (11) has just kept certain relative height like this.This liquid level height is determined to regulate by the total length of regulating adjustable float needle valve.When mixture strength is too rare, unclamping positioning and locking nut (4) screws in screw rod (3) to the needle-valve head, the total length of this device is shortened, fasten position locking nut (4) then, the fuel oil that enters float chamber (11) like this is just more, the pasta of float chamber is just higher, and therefore the mixture strength that enters in the engine chamber (11) is just denseer, otherwise opposite.Pasta in float chamber (11) is during at certain altitude, the power of motor, and the torque maximum, the acceleration Economy is best, the exhaust gas discharged minimum, the fuel head of this moment is only height.
Compared to existing technology, the utlity model has following advantage:
1, manufacturing process is simple, and is easy to adjust;
2, long service life, pollution-free;
3, fuel saving, easy to maintenance.
Claims (2)
1, a kind of adjustable float needle valve, it is characterized in that: float needle valve is made up of needle-valve head, needle-valve tail, screw rod, positioning and locking nut, inner nut, cushion seal pad, be pasted with the cushion seal pad on the front end surface of needle-valve head, its rear portion is that a screwed cavity is an inner nut, needle-valve head and needle-valve tail screw in to inner nut by screw rod, and the positioning and locking nut is fastened on the position that screws of inner nut and screw rod.
2, adjustable float needle valve according to claim 1 is characterized in that, needle-valve tail and screw rod are one.
