Description
Technical field
The utility model belongs to valve technology field, especially relates to a kind of ceramic ball valve combined type ball core.
Background technique
At present, in ball valve industry, ceramic ball valve has the unrivaled advantage of metal ball-valve, such as high wear resistant, highly corrosion resistant and high abrasion-resistance etc., but it also has bottleneck---and large-size ceramic goods sintering technology is weak.Large-sized ceramic products all has the difficulty more much higher than small sized article at the links of preparation process, and yield rate is extremely low.This based article plant engineering preparation technology is very weak, is the biggest obstacle of restriction advanced ceramics goods practical application, so bigbore ceramic ball core is also difficult to batch production always.
Summary of the invention
The purpose of this utility model be to improve prior art deficiency and provide a kind of with Metal Ball core be matrix, inlay that sphere ceramic-seal ring, sealing are reliable, the ceramic ball valve combined type ball core of high wear resistant and high abrasion-resistance.
The purpose of this utility model realizes like this, a kind of ceramic ball valve combined type ball core, be made up of Metal Ball core, be characterized in being respectively equipped with left ceramic-seal ring, left gland, right ceramic-seal ring in the both sides of Metal Ball core, right gland, left ceramic-seal ring, left gland and right ceramic-seal ring, right gland are symmetrical arranged on Metal Ball core, left ceramic-seal ring, right ceramic-seal ring are arranged in the mounting groove on Metal Ball core, and left gland, right gland to be connected with Metal Ball core by screw and to push down left ceramic-seal ring, right ceramic-seal ring respectively.
In order to realize the purpose of this utility model further, can be right ceramic-seal ring endoporus be location fit face, the cooperation of its internal diameter and Metal Ball core adopts small―gap suture, its gap length ensures within the scope of working temperature-29 ~ 200 DEG C, during the temperature difference of 200 DEG C, the size after the thermal expansion of Metal Ball core can not exceed the internal diameter of ceramic-seal ring.
In order to realize the purpose of this utility model further, can be the cylindrical of left ceramic-seal ring be location fit face, the cooperation of its external diameter and Metal Ball core adopts small―gap suture, its gap length ensures when working temperature more than 200 DEG C, during the temperature difference more than 200 DEG C, the size after the thermal expansion of Metal Ball core exceedes the hole size of ceramic-seal ring.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model with Metal Ball core for matrix, inlay sphere ceramic-seal ring, indirectly reach the sealing that full ceramic ball core has reliable, the performances such as high wear resistant, highly corrosion resistant and high abrasion-resistance, the ball core of metallic matrix is with its fabulous resistance to tension in addition, the shortcoming that pottery easily collapses porcelain can be made up, the advantage perfection of pottery and metal is unified by the utility model, create the comprehensive ball core of performance, and the batch production of heavy caliber ceramic valve can have been realized; Right gland, left ceramic-seal ring, left gland and right ceramic-seal ring, right gland are symmetrical arranged on Metal Ball core, because the right and left structure is not identical, the left side is used for more than 200 DEG C operating modes, the right is used for-29 ~ 200 DEG C of operating modes, namely when working temperature-29 ~ 200 DEG C, right ceramic-seal ring endoporus is location fit face, the cooperation of its internal diameter and Metal Ball core adopts small―gap suture, when the temperature difference of about 200 DEG C, size after the thermal expansion of Metal Ball core can not exceed the internal diameter of ceramic-seal ring, and now composite structure is effective, can play solid and reliable sealing pair effect; When working temperature more than 200 DEG C, the cylindrical of left ceramic-seal ring is location fit face, the cooperation of its external diameter and Metal Ball core adopts small―gap suture, when the temperature difference more than 200 DEG C, size after the thermal expansion of Metal Ball core will exceed the hole size of ceramic-seal ring, and now inner hole location can cause seal ring by " spalling ", therefore adopts excircle orientation, now still can ensure that composite structure is effective, play solid and reliable sealing pair effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further details.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
A kind of ceramic ball valve combined type ball core, with reference to Fig. 1, be respectively equipped with left ceramic-seal ring 3, left gland 1, right ceramic-seal ring 5 in the both sides of Metal Ball core 4, right gland 6, left ceramic-seal ring 3, left gland 1 are symmetrical arranged on Metal Ball core 4 with right ceramic-seal ring 5, right gland 6, left ceramic-seal ring 3, right ceramic-seal ring 5 are arranged in the mounting groove on Metal Ball core 4, and left gland 1, right gland 6 to be connected with Metal Ball core 4 by screw and to push down left ceramic-seal ring 3, right ceramic-seal ring 5 respectively.
For adapting to the demand of different temperatures working condition, right ceramic-seal ring 5 endoporus is location fit face, this structure uses when being adapted at working temperature-29 ~ 200 DEG C, the cooperation of its internal diameter and Metal Ball core 4 adopts small―gap suture, its gap length ensures when the temperature difference of 200 DEG C, size after Metal Ball core 4 thermal expansion can not exceed the internal diameter of ceramic-seal ring 5, and now composite structure is effective, can play solid and reliable sealing pair effect.
The cylindrical of left ceramic-seal ring 3 is location fit face, the cooperation of its external diameter and Metal Ball core 4 adopts small―gap suture, use when being adapted at working temperature more than 200 DEG C, its gap length ensures when the temperature difference more than 200 DEG C, size after Metal Ball core 4 thermal expansion exceedes the hole size of ceramic-seal ring 3, and now inner hole location can cause seal ring by " spalling ", therefore changes into " excircle orientation ", now still can ensure that composite structure is effective, play solid and reliable sealing pair effect.
Tapped hole on Metal Ball core 4 can smear plane sealing agent because ball core wall thickness is less so there is " boring thoroughly " problem, to ensure that sealing effectively, and plays the effect improving metal and ceramic ring adhesive strength.
