Problems solved by technology
[0002] During the forming and firing process of all-ceramic valves, because the shrinkage rate of the ceramic blank material formula changes with the temperature in the furnace, it cannot reach a uniform value. At the same time, the temperature difference at different positions in the furnace will also cause the shrinkage rate of the product to be inconsistent. Therefore, the precision of the thread at the ceramic valve interface will be insufficient, and the ceramic material is brittle, so it is easy to cause damage to the thread at the valve interface during the connection with the metal standard fitting.

The invention discloses a ceramic valve connector connecting structure. The ceramic valve connector connecting structure comprises a ceramic pipe body and a metal connecting sleeve. The ceramic pipe body is connected to the connector position and integrally formed with a ceramic valve body. A channel in the ceramic pipe body communicates with a water passing way in the ceramic valve body. The periphery of the end, connected with the ceramic valve body, of the ceramic pipe body is provided with a circle of annular groove. The metal connecting sleeve coaxially sleeves the exterior of the ceramicpipe body. A thread is arranged on the outer wall of one end of the metal connecting sleeve, the other end of the metal connecting sleeve is sleeved with the annular groove, the annular groove is filled with a cured bonding layer, and the metal connecting sleeve and the ceramic valve body are connected into a whole through the bonding layer. By means of the ceramic valve connector connecting structure, reliability of connection with a metal standard accessory can be effectively improved, and water solution cannot be caused.
Description
technical field [0001] The invention relates to the field of ceramic valves, in particular to a connection structure of a ceramic valve interface. Background technique [0002] During the forming and firing process of all-ceramic valves, because the shrinkage rate of the ceramic blank material formula changes with the temperature in the furnace, it cannot reach a uniform value. At the same time, the temperature difference at different positions in the furnace will also cause the shrinkage rate of the product to be inconsistent. Therefore, the precision of the thread at the ceramic valve interface will be insufficient, and the ceramic material is brittle, so it is easy to cause damage to the thread at the valve interface during the connection process with the metal standard fitting. Contents of the invention [0003] The object of the present invention is to provide a connection structure of ceramic valve interface which can improve connection reliability with metal standar...
