Abstract
The invention discloses a conveniently-installed valve core metal core. The metal core is characterized by comprising a core body (1) used for accommodating a core rod, a platform (2) used for accommodating a seal pad is arranged in the core body (1), a through hole used for allowing the core rod to penetrate is formed at the center of the platform (2), and an annular groove (9) used for accommodating the seal pad is arranged on the inner wall of the core body (1) fitting to the upper surface of the platform (2) tightly; the core body (1) comprises a main shell located on the upper surface of the platform (2) and a connecting shell (7) located below the platform (2), and the connecting shell (7) is provided with outer screwed threads (10). The conveniently-installed valve core metal core is convenient to replace and more easy to install, time is saved, the tightness effect is fine, air leakage is prevented, and the metal core is durable and long is service life.
Description
Technical field
The present invention relates to a kind of convenient valve inside metallic core of installing, 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.
Finally, existing valve inside is generally inserted in housing, installs and changes inconvenience, need longer man-hour.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and changes easily, save man-hour, convenient valve inside metallic core of installing; Further, good sealing effect of the present invention, 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:
A kind of convenient valve inside metallic core of installing, 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; Described core body comprises the body shell be positioned at above described platform and the connection shell be positioned at below described platform, and described connection shell is provided with outside thread.
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 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 shape of described body shell is square, and the shape of described connection shell is cylindrical.
The groove for placing gas pressure detector is provided with in described connection shell.
Described gas pressure detector is connected with alarm.
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 convenient valve inside metallic core of installing provided by the invention, externally threaded setting, achieves being threaded of core body and housing, installs to change easy, cost savings man-hour, improves efficiency; 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; 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.A kind of convenient valve inside metallic core of installing provided by the invention, installs and changes easily, save man-hour, and good sealing effect, not easily leak gas, durable in use, long service life.
