It is integrally formed, interior protuberance and outer protuberance are collectively forming circular platform, the center of described circular platform and ring flange
Axis is vertical；The internal diameter of wherein interior protuberance is equal to the internal diameter of the central through hole of described ring flange；Bolt is for by outer protrusion
Portion is fixedly connected with ring flange；Female thread is provided with the inwall of the cylindrical portion of described threaded adapter；Described annular shape
The top surface of platform is brought into close contact with the bottom surface of described ring flange；Bolt hole is additionally provided with described ring flange, bolt hole
The centerline axis parallel of bolt hole center's axis and ring flange.
Internal diameter of the internal diameter of the cylindrical portion of described threaded adapter more than interior protuberance.
The first sealing ring is provided between the bottom surface of the top surface and described ring flange of described circular platform.
Cannelure is provided with the top surface of described ring flange, is provided with the second sealing ring in cannelure.
The cannelure for accommodating the 3rd sealing ring is provided with the bottom surface of described interior protuberance.
The technical solution of the utility model has the advantage that：
The wear-resistant sealing flange being convenient for changing described in the utility model is rational in infrastructure, after thread damage, is not required to
Integral replacing ring flange is wanted, cost, and good sealing effect is greatlyd save, can be by the central through hole with diameter greater than ring flange
The pipeline of internal diameter be connected with ring flange.
Description of the drawings
Fig. 1 is the structural representation of the wear-resistant sealing flange being convenient for changing described in the utility model.
In figure, including：Ring flange 42, bolt hole 44, bolt hole center's axis 46, bolt 48, cannelure 50, top surface 51,
Second sealing ring 61, wear-resistant sealing flange 68, threaded adapter 70, female thread 72, the first sealing ring 74, the 3rd sealing ring
76th, interior protuberance 77, outer protuberance 78.
Specific embodiment
Following examples are used for illustrating this utility model, but are not limited to scope of the present utility model.
As shown in figure 1, the wear-resistant sealing flange 68 being convenient for changing described in the utility model includes threaded adapter 70
With ring flange 42, described threaded adapter 70 includes cylindrical portion, and the top of cylindrical portion is provided with interior protuberance 77 and outer protrusion
Portion 78, interior protuberance 77 and outer protuberance 78 are integrally formed, and interior protuberance 77 and outer protuberance 78 are collectively forming circular platform,
The central axis upright of described circular platform and ring flange 42；Wherein the internal diameter of interior protuberance 77 is equal to described ring flange
The internal diameter of 42 central through hole；Bolt 48 is for outer protuberance 78 is fixedly connected with ring flange 42；Described threaded adapter
Female thread 72 is provided with the inwall of 70 cylindrical portion；The bottom surface of the top surface of described circular platform and described ring flange 42
It is brought into close contact；Bolt hole 44, bolt hole center's axis 46 of bolt hole 44 and ring flange is additionally provided with described ring flange 42
42 centerline axis parallel.
Internal diameter of the internal diameter of the cylindrical portion of described threaded adapter 70 more than interior protuberance 77.
The first sealing ring 74 is provided between the bottom surface of the top surface of described circular platform and described ring flange 42.
Cannelure 50 is provided with the top surface 51 of described ring flange 42, is provided with the second sealing ring 61 in cannelure 50.
The cannelure for accommodating the 3rd sealing ring 76 is provided with the bottom surface of described interior protuberance 77.
The wear-resistant sealing flange being convenient for changing described in the utility model realize pipeline connect when, by pipe end
The external screw thread in portion is screwed into female thread 72, is in close contact pipe end and the bottom surface of interior protuberance 77, and the 3rd sealing ring 76 is realized
Sealing between pipe end and interior protuberance 77.Simultaneously because the bottom of the top surface of circular platform and described ring flange 42
It is in close contact between face, the top surface that the first sealing ring 74 realizes circular platform is close with the bottom surface of described ring flange 42
