Abstract
The utility model relates to a convenient air valve, belonging to the technical field of aeration for various transport wheels. The goal of gas opening and gas closing is reached by a taper step on the upper part of a flow quantity hole (3) and a bullet-shaped single-body rubber pneumatic plug with the same taper step which are pressed by gas. The utility model has the advantages of large aeration quantity, fast gas ingress and egress, strong reliability, long service life, energy saving, work saving and time saving.
Description
The utility model relates to a kind of valve that makes things convenient for, and is used on the wheel especially.Belong to wheel inflation technical field.
The valve that wheel uses is controlled by having the glued membrane screw thread in the air tube insurance.But this technology has such problem, and charge air is little, accounts for the time, glued membrane rapid wear, the easy phenomenon that forms the gas of jogging.Wheel for motor vehicle particularly, the air tube breaking piece is many, causes indirect damage number of times just many more, uses also inconveniently, usually influences the wheel charge-air mass.
What provide in order to solve above-mentioned deficiency makes things convenient for valve.This valve has adopted the independent body rubber rammer of the bullet shape of band tapering to be matched with valve inside, it has, and charge air is big, turnover gas is fast, durability good, good reliability, be subjected to the atmospheric pressure pneumatic open-close, energy-conservation, economize merit time-saving characteristics.
The purpose of this utility model is achieved in that the metering orifice that bores a dosing hole and a band tapering step in the valve main body is connected, the steel wire expansion loop of a spring and a grate shape is set in metering orifice, control an independent body rubber rammer, can only in metering orifice, be subjected to descend atmospherically the motion pneumatic open-close with the bullet shape of same tapering step.After closing source of the gas, rammer is subjected to the gas pressure air to close in the wheel immediately, but spring also has certain booster action, because rammer is the independent body rubber of bullet shape, elasticity is strong, good toughness, easily and the metal covering fitted seal.Thereby reached that pneumatic open-close, durability are good, good reliability, energy-conservation, economize merit time-saving purpose.
The utility model is because a metering orifice at a valve body interior dosing hole of brill and a band tapering step is connected, in establish one less than the metering orifice diameter, make taper fitting with belt transect tapering independent body rubber step, bullet shape rammer, form the air pressure control principle, so simple in structure, realize the requirement of pneumatic open-close easily.
Describe in further detail below with reference to accompanying drawing 1,2 pairs of the utility model of accompanying drawing.
Accompanying drawing 1, accompanying drawing 2 are according to the cutaway view that makes things convenient for valve that the utility model proposes.
With reference to accompanying drawing 1, this utility model makes things convenient for valve to comprise a valve main body (1), the metering orifice (3) that a dosing hole (2) and a band tapering step are bored in main body top is connected, in establish an independent body rubber rammer (4) and make taper fitting with the bullet shape of same tapering step, be subjected to atmospheric pressure to reach pneumatic open-close, its tapering is preferably between 90 °-150 ° to improve the control effect of taper fitting.Dosing hole (2) diameter is 2-4mm, and metering orifice (3) diameter is 4-6mm; The convex surface of rammer (4) bottom inserts spring (5) endoporus and does the flush fit connection, and the steel wire expansion loop (6) of dividing into a grate shape is in position springy do expansion and is tightly fixed.The cross sectional shape of steel wire expansion loop (6) can be that square, oblong, trapezoidal, triangle, semicircle are controlled rammer (4) range of movement (accompanying drawing 2 is the A-A section-drawing).Simultaneously also can be at groove of metering orifice (3) bottom processing, in establish the steel wire expansion loop and finish.Valve main body (1) bottom (not drawing among the figure) can be the multi-groove type that glue is annotated to be needed, and also can be base type.Big nut (7) is stamped on top, in establish rubber pad (8) and be used for inflator and inflate.Big nut (7) top is stamped little nut (9) and is prevented that dirt from entering.
Claims (5)
1, a kind of valve that makes things convenient for, this valve has a dosing hole (2), there is the metering orifice (3) of a band tapering step directly to communicate in its underpart, it is characterized in that making taper fitting with an independent body rubber rammer (4) with the bullet shape of same tapering step with the metering orifice (3) of tapering step, rammer (4) bottom convex surface inserts spring (5) endoporus, spring (5) bottom connects the steel wire expansion loop (6) of grate shape, and steel wire expansion loop (6) expands to be tightly fixed with metering orifice (3) hole face work and has been connected in the elastic force position.
2, according to claims 1 described valve that makes things convenient for, the diameter that it is characterized in that dosing hole (2) is 2-4mm, the center of dosing hole (2) and metering orifice (3) central vertical, and directly communicate.
3, the valve that makes things convenient for according to claim 1 is characterized in that the tapering that cooperates with the metering orifice (3) of tapering step and the independent body rubber rammer (4) of bullet shape is 90 °-150 °, and metering orifice (3) diameter is 4-6mm.
4, the valve that makes things convenient for according to claim 1 is characterized in that rammer (4) bottom convex surface inserts spring (5) endoporus and does the flush fit connection.
5, according to claims 1 described valve that makes things convenient for, the shape that it is characterized in that steel wire expansion loop (6) cross section can be square, oblong, trapezoidal, triangle, semicircle.
