Abstract
The utility model discloses a tyre valve nozzle which is provided with an inflating tube with a base. The internal diameter of the port of the inflating tube is larger than the diameter of the middle hollow cavity of the inflating tube. The diameter of the middle hollow cavity of the inflating tube is larger than the diameter of the lower hollow cavity. The port of the inflating tube is provided with an inflating nozzle. The inside of the inflating nozzle is a hollow cavity, and the upper diameter of the hollow cavity is smaller than the lower diameter. The middle hollow cavity of the inflating tube is provided with a tapered air leakage valve at the inner side, and the lower part of the air leakage valve is connected with a spring. The inner cavity of the inflating tube at the lower part of the spring is provided with a fendering holder. An inflating joint which is arranged on the outer wall of the port of the inflating tube is used for matching inflation. The utility model has the advantages of simple structure, low cost and good tightness, being capable of completely replacing the valve nozzles of the existing various tyres.
Description
The utility model belongs to inflator, relates to a kind of tyre valve to tyre inflation.
The valve cock of existing general motor vehicle tire can not directly be inflated, must use special gas charging valve, or valve inside removed and could inflate, use very inconvenient, and be provided with screw thread as the base top of auto-tire valve, and be equipped with packing ring, nut, it to the fastening-type inner tube of a tyre, prevent the important effect of leaking gas slowly of valve cock root.If but fastening nut, packing ring plays the stripping damage effect to rubber base.When the inner tube of a tyre was packed cover tire into, gas ket, nut had strengthened the space of the inner tube of a tyre and rim strip, the inner tube of a tyre distortion after the inflation, and the inner tube of a tyre is worked in the environment of distortion, has reduced the life-span of the inner tube of a tyre.Valve cock adopts the copper pedestal diameter behind the rubber base still bigger, and this not only brings difficulty to processing, and has wasted a large amount of copper materials.Valve cock on non power driven vehicle such as the bicycle is the valve rubber band to be housed prevent gas leakage on valve inside, but the valve rubber band is easily aging, needs often to change.
The purpose of this utility model provides a kind of simple in structure, good airproof performance, tyre valve easy to use.
The purpose of this utility model is achieved in that described valve cock has a base top and do not have the gas tube that screw thread is unworthy of packing ring and nut, inflation pipe end inner diameter is greater than the diameter of cavities in the gas tube, gas tube middle part cavity diameter is greater than its underpart cavity diameter, port at gas tube is provided with a charging air inlet, it is connected with the gas tube inwall by screw thread, be cavity in the charging air inlet, the upper diameter of cavity is less than lower diameter, one taper steam leak-off valve is set in the cavities in the gas tube, the steam leak-off valve bottom connects a spring, in the gas tube inner chamber of spring bottom a block seat is set, connects one on the gas tube port outer wall and cooperate the gas-charging connection of inflating.
Establish an opening slot on the upper-end surface of charging air inlet, so that fastening or open with screw-driver.A seal ring can be established in periphery, charging air inlet bottom, in order to the enhanced leaktightness degree.
Described steam leak-off valve is also spherical.
One pore is set in the middle of the block seat, also is provided with inlet hole around on block seat.
Be cavity in the described gas-charging connection, cavity is relative with the cavity of charging air inlet.
From the above mentioned, the utility model has saved the gas charging valve of present use, the plunger key, make reasonable integral structure, simple, and saved copper material, reduced cost and difficulty of processing, easy to use, good airproof performance is inflated more light, flexible, quick, long service life, can replace the valve cock on the existing various tires fully.
Below in conjunction with embodiment the utility model is further described.
Accompanying drawing 1 is a kind of bending valve cock structural representation of motor vehicle.
Valve cock shown in the figure has the gas tube 2 that a base 1 top does not have screw thread, packing ring and nut, and gas tube 2 port internal diameters are greater than the diameter of cavities in the gas tube 2, and gas tube 2 middle part cavity diameters are greater than its underpart cavity diameter.Port at gas tube 2 is provided with a charging air inlet 6, it is connected with gas tube 2 inwalls by screw thread, is cavity in the charging air inlet 6, and the upper diameter of cavity is less than lower diameter, one taper steam leak-off valve 5 is set in the cavities in the gas tube 2, and it can closely cooperate with the cavity of charging air inlet 6.Steam leak-off valve 5 bottoms connect a spring 4, and spring 4 bottoms are a block seat 3, and block seat 3 is stuck in gas tube 2 middle parts and lower cavity junction point.Establish a pore in the middle of the block seat 3, and also be provided with inlet hole in one week.The gas-charging connection of inflating with the cooperation that is threaded on the gas tube 2 upper end outer walls 8, gas-charging connection 8 inside are cavity, cavity is relative with the inner chamber of charging air inlet 6, install for convenience, on the upper-end surface of charging air inlet 6, establish an opening slot, charging air inlet 6 bottom outer periphery one seal ring 7 is used for the enhanced leaktightness degree, and described steam leak-off valve 5 also can be sphere.
During inflation, tracheae is enclosed within on the gas-charging connection 8, pressurized gas enter into charging air inlet 6 inner chambers by gas-charging connection 8 inner chambers, compressing steam leak-off valve 5, inner chamber away from charging air inlet 2, gas enters into tube from the pore on the block seat 3, charge gas after, inner tube of a tyre gas compressing steam leak-off valve 5 enters into the inner chamber of charging air inlet 6 inner chamber bottoms sealing charging air inlet 6.
