Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to an integrated valve seat assembly structure with rubber coating. Background Technology

[0002] Traditional metal faucets, where the valve seat and inlet / outlet pipes are both metal, are typically connected by direct welding, as provided in the patent (CN214789281U).

[0003] When the valve seat is made of non-metallic material, while the inlet / outlet pipes and valve body are metal, rubber rings are typically assembled first at the inlet / outlet holes on the valve seat, then the inlet / outlet pipes are assembled, and finally, the metal valve body holes and the inlet / outlet pipes are welded together at the closest points, as per the instruction manual. Figure 21 Because the rubber rings may shift during the secondary assembly of the inlet and outlet pipes, they may not be on the same plane, resulting in poor sealing. Furthermore, repeatedly inserting and removing the rubber rings wastes manpower and increases the product defect rate. Alternatively, rubber gaskets can be used instead of rubber rings, as shown in the instruction manual. Figure 22 However, this method also has the problems of poor sealing and complicated process and high requirements due to the need to insert rubber gaskets multiple times. Utility Model Content

The valve seat includes a valve seat body and a connector. The valve seat body is disposed within the mounting cavity, and the connector extends from the housing bore and seals the housing bore. The valve seat has a water passage. One end of the water passage forms a water passage hole at the end of the valve seat body and connects to the mounting cavity.

This can avoid the problem of the sealing ring shifting when the connector is plugged in, improve the sealing performance and sealing reliability. In addition, it also reduces the complexity of assembly, increases the assembly speed and improves the yield rate.

[0009] Preferably, the casing is made of metal, which is hard and has a good texture.

[0011] Preferably, the diameter of the mating end of the connector is larger than the diameter of the shell hole.

[0012] Preferably, the mating end of the connector is provided with external threads to facilitate connection with pipes.

[0013] Preferably, the mounting cavity is provided with a convex ring, which abuts against the end of the valve seat body to improve the firmness of the valve seat after molding.

[0014] Preferably, the connector includes an inlet connector and an outlet connector, and the water passage includes an inlet passage and an outlet passage.

[0015] Preferably, the water inlet connector includes a cold water connector and a hot water connector, the water inlet channel includes a cold water channel and a hot water channel, and the water outlet channel is a mixed water channel.

[0016] Preferably, the top of the valve seat is provided with a valve core mounting groove, or the space at the top of the valve seat where the mounting cavity is located forms the valve core mounting groove.

[0017] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0018] The valve seat structure provided by this utility model adopts a method of molding the valve seat by overmolding the shell, so that the valve seat and the shell are integrated, which can avoid the problem of the sealing ring shifting when the connector is plugged in, improve the sealing performance and sealing reliability. In addition, it also reduces the complexity of assembly, and improves the yield rate while increasing the assembly speed.
