In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a connection structure of ceramic valve interface, its includes ceramic body and metal connecting sleeve, the ceramic body is connected in the kneck and with ceramic valve body integrated into one piece, the inside passageway of ceramic body and the inside water service passage intercommunication of ceramic valve body, the ceramic body is equipped with round annular groove with the one end periphery of ceramic valve body coupling, the metal connecting sleeve is coaxial to be established outside the ceramic pipe body with the cover, is equipped with the screw thread on the one end outer wall of metal connecting sleeve, and the other pot head of metal connecting sleeve is located in the annular groove, the annular groove intussuseption is filled with the adhesive layer of consolidation, and this adhesive layer links into an organic whole with ceramic valve body with the metal connecting sleeve.

The groove wall of the annular groove is provided with at least one bayonet, the bayonet comprises a linear sliding groove arranged along the axial direction, and the bottom of the linear sliding groove is connected with an arc-shaped clamping groove arranged along the circumferential direction; the outer wall of the other end of the metal connecting sleeve is provided with clamping blocks corresponding to the bayonets which are integrally formed, and the clamping blocks slide into the annular groove along the linear sliding groove and are clamped into the arc-shaped clamping grooves after rotating.

The bayonet socket is two, and two bayonet sockets are central symmetry about the axle center of annular groove.

The metal connecting sleeve is formed by copper or stainless steel.

The utility model adopts the above technique, following beneficial effect has:

1. the ceramic pipe body integrally formed with the ceramic valve body is designed at the interface of the ceramic valve, so that the water body still flows from the inside of the ceramic pipe body and is not in direct contact with the metal connecting sleeve, and the water body cannot be polluted.

2. The metal connecting sleeves are bonded and fixed in the annular grooves by adhesives in a seamless mode, connection is reliable and stable, and borne torque meets the industrial standard and the water pressure test standard. In addition, the threads on the outer wall of the metal connecting sleeve are connected with the metal standard fittings, so that the problems of low precision and easiness in damage of the ceramic threads can be effectively solved, and the connection reliability of the valve and the external metal standard fittings is effectively guaranteed.

3. The clamping block and the bayonet are matched, so that the joint can be prevented from falling off under the action of axial tensile force under the action of water pressure.
