Abstract
The utility model discloses a kind of valve inside metallic core, it is characterized in that: comprising: for placing the core body (1) of core bar, the platform (2) for placing sealing gasket is provided with in described core body (1), described platform (2) center is provided with for the through hole (3) through described core bar, described core body (1) outer wall is provided with the first ring connected in star (4) for placing the first seal ring and the second annular groove (5) for placing the second seal ring.A kind of valve inside metallic core that the utility model provides, good sealing effect, not easily leaks gas, durable in use, long service life, is easy to apply.
Description
Technical field
The utility model relates to a kind of valve inside metallic core, belongs to valve technology field.
Background technique
Valve inside is airtight core again, is an one-way cock, is mainly used in the inflation/deflation of tire.The most key part of valve inside is seal ring.If seal ring is blocked by foreign material or agingly to break, all can leak gas.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of good sealing effect, the valve inside metallic core of not easily leaking gas.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of valve inside metallic core, it is characterized in that: comprising: for placing the core body of core bar, the platform for placing sealing gasket is provided with in described core body, described Platform center is provided with for the through hole through described core bar, described core body outer wall is provided with the first ring connected in star for placing the first seal ring and the second annular groove for placing the second seal ring.
Described first seal ring is metal o-ring.
Described second seal ring is rubber seal.
Described core body comprises the connection shell being positioned at body shell above described platform and being positioned at below described platform, and described body shell is with to be connected shell one-body molded, and described first ring connected in star and the second annular groove are all positioned in described body shell.
Described body shell is square.
The width of described body shell is greater than the width of described connection shell.
The material of described core body comprises brass.
A kind of valve inside metallic core that the utility model provides, be provided with two seal rings, namely the first seal ring and the second seal ring, achieve double seal, greatly reduces due to the aging of seal ring or blocked the gas leak phenomenon caused by foreign material; In addition, because the first seal ring is metal o-ring, namely the material of the first seal ring is metal, this kind of setting makes the first seal ring not easily break down, deterioration phenomenon can not occur or blocked by foreign material, ensure that the sealing effect of core body further, valve inside not easily leaks gas; First ring connected in star and the second annular groove are all positioned at the setting in body shell, and body shell is square setting, ensure that the first seal ring and the second seal ring not easily move, and avoid the distortion of the first seal ring because internal friction causes and the second seal ring.A kind of valve inside metallic core that the utility model provides, good sealing effect, not easily leaks gas, durable in use, long service life, is easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of valve inside metallic core, it is characterized in that: comprising: for placing the core body 1 of core bar, the platform 2 for placing sealing gasket is provided with in described core body 1, described platform 2 center is provided with for the through hole 3 through described core bar, described core body 1 outer wall is provided with the first ring connected in star 4 for placing the first seal ring and the second annular groove 5 for placing the second seal ring.
Described first seal ring is metal o-ring.
Described second seal ring is rubber seal.
Described core body 1 comprises the connection shell 7 being positioned at body shell above described platform 26 and being positioned at below described platform 2, and described body shell 6 is with to be connected shell 7 one-body molded, and described first ring connected in star 4 and the second annular groove 5 are all positioned in described body shell 6.
The width of described body shell 6 is greater than the width of described connection shell 7.
The material of described core body 1 comprises brass.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
