Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic shells, and particularly relates to a composite toughened alumina ceramic valve core shell. Background Art

[0002] Most of the existing valve core shells use metal materials as the main materials. For the existing composite toughened alumina ceramic valve core shells, due to excessive friction between the internal components of the shell and the shell, components such as valve stems, moving pieces, and static pieces are easily damaged. Rusting of the valve core shell will affect water quality. It is not as good as alumina ceramics in terms of good conductivity, mechanical strength, and high temperature resistance. The fixing property is not good enough, not firm enough, the sealing property is also poor, and the clamping connection is very easy to slip, which greatly affects the use in daily life.

[0003] The Chinese utility model patent with the publication number of CN210830736U, a composite toughened alumina ceramic valve core shell, includes an installation shell body. A ring plate is coaxially arranged at the top of the installation shell body, and a first connection block is coaxially connected to the top of the second connection block. A plurality of first annular rubber blocks are coaxially connected to the inner wall of the installation shell body. One end of the installation shell body far from the second connection block is coaxially connected with a sealing base. A connecting pipe is coaxially connected to one side of the sealing base close to the installation shell body. A plurality of fourth annular rubber blocks are coaxially connected to the outer wall of the connecting pipe. A plurality of second annular grooves are equidistantly arranged at corresponding positions on the inner wall of the installation shell body. A third annular groove is coaxially and fixedly connected to one end of the installation shell body close to the sealing base. A third annular rubber block is arranged at the corresponding position on the top of the sealing base. The structure of the utility model is simple and effectively protects the valve core, thereby improving the working efficiency of the device.

[0004] However, the above-mentioned utility model patent has the following technical problems in actual use:

[0005] First, the installation shell body, the second connection block, and the sealing base in the above device are designed with an integral structure. Although the overall strength of the above device is enhanced, it also makes the above device not easy to disassemble, which will affect the quick installation of the valve body and reduce the installation efficiency.
