Abstract
The invention discloses a high-tightness metal core body of a valve core. The high-tightness metal core body is characterized by comprising a core body (1) used for arranging a core mandrel, the inside of the core body (1) is provided with a platform (2) used for arranging a sealing pad, the center of the platform (2) is provided with a through hole (3) used for allowing the core mandrel to penetrate, the outer wall of the core body (1) is provided with a first annular groove (4) used for arranging a first sealing ring and a second annular groove (5) used for arranging a second sealing ring, and the inner wall of the core body (1) close to the upper surface of the platform (2) is provided with an annular groove (9) used for arranging the sealing pad. The high-tightness metal core body of the valve core is good in sealing effect, less prone to air leak, durable and long in service life. Besides, the high-tightness metal core body has an alarm function and is capable of more accurately displaying real tire pressure of an inflated tire and easy to popularize 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.
The sealing gasket of existing valve inside is all directly be placed on the platform of valve inside inside, and to sealing gasket neither one restriction effect, sealing gasket easily leaks 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, sealing gasket is limited in annular groove by the present invention, and the width of annular groove is greater than the width of body shell, and namely the width of sealing gasket is greater than the width of body shell, good sealing effect, and sealing gasket not easily leaks gas; 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 being 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, the inwall being close to the described core body of the upper surface of described platform being provided with the annular groove for placing described sealing gasket.
Also being provided with of upper surface of described platform increases bubble-tight capillary structure.
Described capillary structure is tiny fold.
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.
The groove for placing gas pressure detector is provided with in described connection shell.
Described gas pressure detector is connected with alarm.
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 setting of annular groove, is limited to sealing gasket in annular groove, and the width of annular groove is greater than the width of body shell, and namely the width of sealing gasket is greater than the width of body shell, good sealing effect, and sealing gasket not easily leaks gas; The setting of capillary structure, further increase the frictional force of the surface of contact of sealing gasket and platform, sealing strengthens further.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.
