Abstract
The utility model discloses a kind of double-sealing tyre valve, comprise valve body, lower end is arranged on axle core in valve body, be arranged on upper seal ring between valve body and axle core, be arranged on lower seal between valve body and axle core; Valve body is provided with the primary sealing area for contacting with lower seal; The inside of the opening end of valve body being provided with the O-ring cylinder for contacting with upper seal ring, being connected with O-ring cylinder and sealing cone for contacting with upper seal ring.The utility model can reduce the air leakage of valve nozzles phenomenon occurred under the normal service condition of tire, and, also can reduce, even can avoid the air leakage of valve nozzles phenomenon that causes because tire instantaneous pressure increases; In addition, structure of the present utility model is simple, easy to assembly, is conducive to promoting.
Description
Technical field
The utility model relates to a kind of double-sealing tyre valve.
Background technique
Tyre valve charges and discharges gas or liquid as tire, and the one-way cock of pressing in keeping and detect, be widely used in tire.The axle core that existing tyre valve generally comprises valve body, lower end is arranged on valve body.But because the sealing effect between valve body and axle core is poor, cause and easily occur air leakage of valve nozzles phenomenon when tire used, far can not meet people's requirement.
Model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of double-sealing tyre valve, and it can reduce air leakage of valve nozzles phenomenon.
For solving the problem, the technological scheme that the utility model adopts is as follows:
Double-sealing tyre valve, comprises valve body, lower end is arranged on axle core in valve body, is arranged on upper seal ring between valve body and axle core, is arranged on lower seal between valve body and axle core; Described valve body is provided with the primary sealing area for contacting with lower seal; The inside of the opening end of described valve body being provided with the O-ring cylinder for contacting with upper seal ring, being connected with O-ring cylinder and sealing cone for contacting with upper seal ring.
Described sealing cone is positioned at the below of O-ring cylinder.
Described axle core is threaded with valve body.
The outside of described axle core offers the first ring connected in star installed for lower seal.
The outside of described axle core offers the second annular groove kept supplying seal ring and install.
The upper end of described valve body is provided with outside thread.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by adopting the combination design of upper seal ring and lower seal, and by being provided with O-ring cylinder, sealing cone in valve body, the sealing effect between valve body and axle core can be improved, thus the air leakage of valve nozzles phenomenon occurred under the normal service condition of tire can be reduced; And, when tire be subject to colliding suddenly internal pressure improve instantaneously time, and by utilizing lower seal, the pressure of the gas after lower seal can be made to reduce, and seal upper seal ring due to the O-ring cylinder of valve body, sealing cone simultaneously, also can reduce, even can avoid the air leakage of valve nozzles phenomenon that causes because tire instantaneous pressure increases, thus, the utility model all can reduce under the various behaviours in service of tire, even can avoid air leakage of valve nozzles phenomenon; In addition, structure of the present utility model is simple, easy to assembly, is conducive to promoting.

Fig. 2 is explosive view of the present utility model;
Wherein, 1, valve body; 11, O-ring cylinder; 12, sealing cone; 2, axle core; 3, upper seal ring; 4, lower seal.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, understands the utility model technical thought required for protection so that clearer.
As shown in Figure 1, 2, for double-sealing tyre valve of the present utility model, comprise valve body 1, lower end is arranged on axle core 2 in valve body 1, be arranged on upper seal ring 3 between valve body 1 and axle core 2, be arranged on lower seal 4 between valve body 1 and axle core 2; Described valve body 1 is provided with the primary sealing area for contacting with lower seal 4; The inside of the opening end of described valve body 1 being provided with the O-ring cylinder 11 for contacting with upper seal ring 3, being connected with O-ring cylinder 11 and sealing cone 12 for contacting with upper seal ring 3.
Preferably, described sealing cone 12 is positioned at the below of O-ring cylinder 11.
Preferably, described axle core 2 is threaded with valve body 1, to be convenient to the connection between axle core 2 and valve body 1, thus can improve both efficiency of assembling.
Preferably, the outside of described axle core 2 offers the first ring connected in star installed for lower seal 4, to be convenient to the installation of lower seal 4.
Preferably, the outside of described axle core 2 offers the second annular groove kept supplying seal ring 3 and install, to be convenient to the installation of upper seal ring 3.
Preferably, the upper end of described valve body 1 is provided with outside thread.
Wherein, the material etc. of described upper seal ring 3, lower seal 4 can set according to actual demand, as long as can play seal action.
Assembly process of the present utility model is as follows: be first arranged in the first ring connected in star of axle core 2 by lower seal 4, then upper seal ring 3 is arranged in the second annular groove of axle core 2, finally axle core 2 is threaded in valve body 1, thus the assembling of valve cock can be realized fast.
Under the normal service condition of tire, the utility model is by adopting the combination design of upper seal ring 3 and lower seal 4, the sealing effect between valve body 1 and axle core 2 can be improved, to reduce the air leakage of valve nozzles phenomenon occurred under the normal service condition of tire; And when tire is subject to that suddenly collision causes internal pressure to improve instantaneously, by utilizing lower seal 4, the pressure of the gas after lower seal 4 can be made to reduce, and seal seal ring 3 due to the O-ring cylinder 11 of valve body 1, sealing cone 12 simultaneously, thus can reduce, even can avoid the air leakage of valve nozzles phenomenon that causes because tire instantaneous pressure increases.Thus, the utility model all can reduce, even can avoid air leakage of valve nozzles phenomenon under the various behaviours in service of tire.
Above-mentioned mode of execution is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
