Description
Technical field
The utility model is related to a kind of valve protecting cover of tire, more particularly to a kind of aluminium alloy valve leakproof gas shielded
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.
Utility model content
In order to solve the above problems, the utility model provides a kind of aluminium alloy valve anti-gas-leak protective cap.
The technical solution adopted in the utility model is：A kind of aluminium alloy valve anti-gas-leak protective cap, it is characterised in that including
Aluminium alloy 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 is less than linkage section internal diameter, and a shoulder is formed between linkage section and seal section, is provided with what is be adapted to valve inside linkage section
Hypomere internal thread, cap is threadedly attached in seal section, and center is provided with prismatic depression, cap inner face above cap
Annular groove is provided with, sealing gasket has been provided with a ring segment, and ring segment inner edge is provided with the annular ring of embedded annular groove, outside ring segment bottom
Edge is provided with the annular protrusion being pressed on shoulder, and annular protrusion inner face is the up-small and down-big conical surface, conical surface lower edge and shoulder inner edge pair
Together.
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 utility model is used, and valve termination is clamp-oned the conical surface and held out against in ring segment
On, it is possible to implement effective sealing, Reusability sealing gasket is not fallen out yet, and sealing function can be played when valve is leaked,
Reduce inflator meeting, and valve both sides pressure difference it is small can also reduce its fatigue, raising service life.

Specific embodiment
As shown in Figure 1, 2, 3, the aluminium alloy valve anti-gas-leak protective cap is provided with aluminium alloy connection to the utility model embodiment
Sleeve pipe, cap 1 and rubber gasket, connection sleeve pipe hypomere are linkage section 2, and connection sleeve pipe epimere is seal section 3, seal section internal diameter
Less than linkage section internal diameter, a shoulder 4 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 5 above cap, is revolved for screwing in
Go out, cap inner face is provided with annular groove 6, sealing gasket has been provided with a ring segment 7, and ring segment inner edge is provided with the annular ring of embedded annular groove
8, ring segment 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, the conical surface
Lower edge aligns with shoulder inner edge；Cap inner face center is provided with embedded ring segment middle part and downward below no more than under ring segment
Raised the 11 of face, prevent sealing gasket crimp to be brought to middle top pressure valve.
Protective cap linkage section is spun on valve when the utility model is used, and valve termination is clamp-oned the conical surface and held out against in ring segment
On, it is possible to implement effective sealing, Reusability sealing gasket is not fallen out yet, and sealing function can be played when valve is leaked,
Reduce inflator meeting, and valve both sides pressure difference it is small can also reduce its fatigue, raising service life.
It is only in sum the utility model preferred embodiment, all equivalent modifications done according to the application and prior art add
Plus it is accordingly to be regarded as the utility model technology category.
