Abstract
The invention discloses an air leakage prevention protective cap for an aluminum alloy air valve. The air leakage prevention protective cap for the aluminum alloy air valve is characterized in that the air leakage prevention protective cap comprises an aluminum alloy connecting sleeve pipe, a cap cover and a seal cushion, the lower section of the connecting sleeve pipe is a connecting section, and the upper section of the connecting sleeve pipe is a seal section; the inner diameter of the seal section is smaller than that of the connecting section, a circular bead is formed between the connecting section and the seal section, and a lower-section inner thread matched with an air tap is arranged in the connecting section; the cap cover is connected into the seal section through a thread, a prism-shaped sunken portion is formed in the center position on the cap cover, and an annular groove is formed in the inner face of the cap cover; an annular piece is arranged on the seal cushion, an annular ring embedded in the annular groove is arranged on the inner edge of the annular piece, and an annular protrusion pressed on the circular bead is arranged on the outer edge of the lower portion of the annular piece; and the inner face of the annular protrusion is a conical face with a small upper portion and a large lower portion, and the lower edge of the conical face is flush with the inner edge of the circular bead. According to the air leakage prevention protective cap for the aluminum alloy air valve, effective sealing can be implemented, the seal cushion cannot come off when being repeatedly used, the sealing effect can be achieved when deflation is conducted by the air valve, and the differential pressure of the two sides of the air valve is small, so that fatigue of the air valve is reduced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of valve protecting cover of tire, more particularly to a kind of aluminium alloy valve anti-gas-leak protective cap.
Background technology
Valve is designed with the valve of automobile tire, valve inflation/deflation is influenceed in order to prevent foreign matter from entering valve, in valve
Place is designed with the protective cap being connected through a screw thread, and existing protective cap all simply plays a part of to stop that foreign matter enters, and
Valve does not have sealing function when losing heart, and this still awaits technological improvement.
The content of the invention
In order to solve the above problems, the invention provides a kind of aluminium alloy valve anti-gas-leak protective cap.
The technical solution adopted by the present invention is：A kind of aluminium alloy valve anti-gas-leak protective cap, it is characterised in that closed including aluminium
Golden connection sleeve pipe, cap and sealing gasket, connection sleeve pipe hypomere are linkage section, and connection sleeve pipe epimere is seal section, seal section internal diameter
Less than linkage section internal diameter, a shoulder is formed between linkage section and seal section, the hypomere being adapted to valve is provided with inside linkage section
Internal thread, cap is threadedly attached in seal section, and center is provided with prismatic depression above cap, and cap inner face is provided with
Annular groove, sealing gasket has been provided with a ring segment, and ring segment inner edge is provided with the annular ring of embedded annular groove, and ring segment bottom outer rim sets
There is the annular protrusion being pressed on shoulder, annular protrusion inner face is the up-small and down-big conical surface, and conical surface lower edge aligns with shoulder inner edge.
Further, the cap inner face center is provided with embedded ring segment middle part and is no more than ring segment downward below
Following projection.
Protective cap linkage section is spun on valve when the present invention is used, and valve termination is clamp-oned the conical surface and held out against on ring segment, can
To implement effective sealing, Reusability sealing gasket is not fallen out yet, and sealing function can be played when valve is leaked, and reduction is filled
Mechanism of qi meeting, and valve both sides pressure difference it is small can also reduce its fatigue, improve service life.

Specific embodiment
The embodiment of the present invention as shown in Figure 1, 2, 3, the aluminium alloy valve anti-gas-leak protective cap be provided with aluminium alloy connection sleeve pipe,
Cap 1 and rubber gasket, connection sleeve pipe hypomere are linkage section 2, and connection sleeve pipe epimere is seal section 3, and seal section internal diameter is less than
Linkage section internal diameter, forms a shoulder 4 between linkage section and seal section, and spiral shell in the hypomere being adapted to valve is provided with inside linkage section
Line, cap is threadedly attached in seal section, and center is provided with prismatic depression 5 above cap, is screwed out for screwing in, cap
Lid inner face is provided with annular groove 6, and sealing gasket has been provided with a ring segment 7, and ring segment inner edge is provided with the annular ring 8 of embedded annular groove, ring
Shape piece bottom outer rim is provided with the annular protrusion 9 being pressed on shoulder, and annular protrusion inner face is the up-small and down-big conical surface 10, conical surface lower edge
Alignd with shoulder inner edge；Cap inner face center is provided with embedded ring segment middle part and downward below no more than below ring segment
Raised 11, prevent sealing gasket crimp to be brought to middle top pressure valve.
Protective cap linkage section is spun on valve when the present invention is used, and valve termination is clamp-oned the conical surface and held out against on ring segment, can
To implement effective sealing, Reusability sealing gasket is not fallen out yet, and sealing function can be played when valve is leaked, and reduction is filled
Mechanism of qi meeting, and valve both sides pressure difference it is small can also reduce its fatigue, improve service life.
It is only in sum present pre-ferred embodiments, all equivalent modifications done according to the application and prior art addition are equal
It is considered as the technology of the present invention category.
