Abstract
The invention discloses a valve core metal core high in air tightness. The valve core metal core body is characterized by comprising a core body (1), a platform (2) used for placing a sealing gasket is arranged in the core body (1), a through hole (3) used for allowing a core bar to penetrate is arranged in the middle of the platform (2), and a first ring groove (4) used for placing a first sealing ring and a second ring groove (5) used for placing a second sealing ring are arranged in the outer wall of the core body (1); the core body (1) comprises a main shell (6) located above the platform (2) and a connecting shell (7) located under the platform (2), and an air pressure detector (8) is arranged in the connecting shell (7). The valve core metal core which has a warning function is good in sealing effect, less prone to air leakage, durable in use, long in service life, capable of displaying real tire pressure of an inflated tire more accurately and easy to promote and apply.
Description
Technical field
The present invention relates to the valve inside metallic core that a kind of tightness is strong, belong 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.
In addition, the device for monitoring tyre pressure of existing valve inside is generally positioned at from the place away from pneumatic tire, tire pressure show value and actual value slightly deviation.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of good sealing effect, not easily leaks gas, the valve inside metallic core that tightness is strong; Further, device for monitoring tyre pressure is arranged at the nearer place of distance pneumatic tire by the present invention, namely connects in shell, can show the true tire pressure being inflated tire more exactly.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The valve inside metallic core that a kind of tightness is strong, 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 core body comprises the body shell be positioned at above described platform and the connection shell be positioned at below described platform, is provided with gas pressure detector in described connection shell.
Described gas pressure detector is connected with alarm.
Described first seal ring is metal o-ring.
Described second seal ring is rubber seal.
(one-body molded, described first ring connected in star and the second annular groove are all positioned in described body shell described body shell with being connected 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.
The valve inside metallic core that a kind of tightness provided by the invention is strong, is provided with two seal rings, and namely the first seal ring and the second seal ring, achieve double seal, greatly reduces due to the aging of seal ring or is 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; Connect the design being provided with gas pressure detector in shell, the true tire pressure being inflated tire can be shown more exactly; The design that gas pressure detector is connected with alarm, can and alarm.The valve inside metallic core that a kind of tightness provided by the invention is strong, good sealing effect, not easily leaks gas, durable in use, and long service life has warning function, and can show the true tire pressure being inflated tire more exactly, is easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, the valve inside metallic core that a kind of tightness is strong, 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 core body 1 comprises the body shell 6 be positioned at above described platform 2 and the connection shell 7 be positioned at below described platform 2, is provided with gas pressure detector 8 in described connection shell 7.
Described gas pressure detector 8 is connected with alarm.
Described first seal ring is metal o-ring.
Described second seal ring is rubber seal.
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 the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
