Abstract
The utility model relates to a novel matching structure of a valve core and a valve seat. The valve core is provided with a ceramic spherical sealing surface, the valve seat is provided with an inner arc-shaped sealing ring at a position corresponding to the sealing surface, the sealing ring is tightly matched with the ceramic spherical sealing surface and is concentric with the ceramic spherical sealing surface, and the sealing surface of the valve core and the sealing ring seat form a hyperbolic sealing structure. Since the contact surface of the valve core and the valve seat adopts the ceramic arc-shaped contact, the utility model has the advantages that the matching structure achieves better sealing effect, is wear-resistant, and prolongs the service life of the whole valve. Due to self-lubrication of the ceramic, the novel matching structure can achieve higher sealing performance. Moreover, due to self-enrichment of the ceramic, the novel matching structure is more resistant to erosion of media and has a longer service life.
Description
Technical field:
The utility model relates to a kind of valve fittings, and especially long with a life-span, Security is higher, and the better novel spool of wear-resistant and sealing effect is relevant with the cooperating structure of valve seat.
Background technique:
In at present traditional valve, no matter ball valve, semispherical valve still are butterfly valve or the like, it is that valve plate is that metal contacts with the point or the line of metal when being in closed condition with valve port that its spool and the cooperation of valve seat mostly are the metal hard structure, perhaps be the contact of softwood matter, the cooperating structure of above-mentioned spool and valve seat is because its line seal, its sealing effect is poor, leak easily, and the life-span is short.
Summary of the invention:
The utility model purpose is to overcome above-mentioned shortcoming, and the cooperating structure of a kind of novel spool and valve seat is provided, and it has, and the life-span is long, and Security is higher, the characteristics that wear-resistant and sealing effect is better.
For reaching above-mentioned purpose, the utility model adopts following technological scheme:
The cooperating structure of a kind of novel spool and valve seat, spool is provided with ceramic ball face seal face, the position of corresponding sealing surface is provided with one and closely cooperates and the intrados seal ring concentric with it with ceramic ball face seal face on the valve seat, and described sealing surface and seal ring are the hyperbola sealing configuration.
Adopt technique scheme, its advantage is: because spool contacts for ceramic arc surface with the surface of contact of valve seat, sealing effect is better, and it is wear-resistant, prolong the working life of whole valve, and because the self-enrichment of pottery itself can make also its sealability better.And because the characteristic of pottery itself makes its more washing away of media-resistant, the life-span is longer.
Description of drawings:
Below with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representations;
Fig. 3 is the utility model embodiment three structural representations.
Embodiment:
Below in conjunction with drawings and Examples the utility model is described in detail:
Mode of execution of the present utility model as shown in Figure 1-Figure 3, the cooperating structure of a kind of novel spool and valve seat, spool is provided with ceramic ball face seal face 1, the position of corresponding sealing surface is provided with one and closely cooperates and the intrados seal ring seat 2 concentric with it with ceramic ball face seal face on the valve seat, and described valve core sealed cover and seal ring seat are the hyperbola sealing configuration.
Because valve plate contacts for ceramic arc surface with the surface of contact of valve seat, sealing effect is better, and wear-resistant, prolongs the working life of whole valve, and because the self-enrichment of pottery itself also can make its sealability better.And because the characteristic of pottery itself makes its more washing away of media-resistant, the life-span is longer.
Structure of the present utility model can be used on the multiple valve, as ball valve, semispherical valve, butterfly valve or the like, as long as adopt the cooperating structure in the utility model claim scope to be protection domain of the present utility model.
