Description
Technical field
The utility model relates to outlet valve field, especially a kind of faucet valve core.
Background technique
Currently, the Chinese utility model patent of disclosed Patent No. CN201620427523.9 discloses one kind on the market
Faucet valve core, including upper valve body, lower valve body, are connected through a screw thread between the upper valve body and the lower valve body, the upper valve
The lateral wall of body is additionally provided with the external screw thread connecting with tap shell, the other end of the lower valve body relative to the upper valve body
It is provided with sealing ring；The faucet valve core is mutually fitted in the external screw thread of upper valve body on tap when installing with tap shell
When the internal screw thread matched mutually rotates connection, since lower valve body is also to be threadably secured to connect with upper valve body, lower valve body can be with
Upper valve body rotates together, and when the sealing ring in lower valve body is contacted with tap shell, lower valve body is rotated relative to tap shell,
Mutual extrusion spin friction makes sealing ring be easy the position sealed required for deviateing between lower valve body, sealing ring and tap shell
Cause water tap leakage.
Utility model content
Based on the above issues, the utility model provides a kind of faucet valve core, does not make faucet valve core during the installation process not
Spin friction can be generated to sealing ring allows sealing ring deviation that the position sealed is needed to cause water tap leakage.
To achieve the above object, the utility model provides following technical solution: a kind of faucet valve core, including upper valve
Body, lower valve body, sealing ring, one end that the lower valve body corresponds to the upper valve body are provided with upper surface, and the upper valve body corresponds to institute
The one end for stating lower valve body is provided with lower end surface, and the sealing ring is set to the lower valve body relative to the another of the upper valve body
End, the upper valve body socket-connect with the lower valve body, and boss, the upper valve body and the lower valve body are provided in the lower valve body
