Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a valve seat assembly structure for sealing the interface with a rubber coating layer. 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 26 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 27 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

[0058] The periphery of the housing 1 is provided with a shell hole 12 that communicates with the mounting cavity 11.

[0059] The valve seat 3 is installed in the mounting cavity 11 and is provided with a water passage 31. One end of the water passage 31 forms a water passage hole 311 at the end of the valve seat 3. A mating interface 312 is formed on the periphery of the valve seat 3. The mating interface 312 is aligned with the shell hole 12 and has an inner coating layer 3121. In one embodiment, to improve the tightness of the connection between the mating interface 312 and the coating layer 3121, the inner wall of the mating interface 312 has a protrusion or a groove, and the coating layer 3121 covers the protrusion or groove. Alternatively, in another embodiment, the coating layers 3121 of the mating interface 312 are connected by ribs, resulting in stronger integration. Figure 25 The fifth implementation shown.

[0060] The connector 4 is made of metal, with one end being a mating end 41. The mating end 41 passes through the shell hole 12 and is inserted into the mating interface 312. A seal is formed between the periphery of the mating end 41 and the mating interface 312 by an adhesive layer 3121. In one embodiment, the mating interface 312 is stepped, and the adhesive layer 3121 covers the stepped surface of the mating interface 312 to form an end seal.

[0061] In one embodiment, the periphery of the interface 312 is provided with an annular groove, and a sealing ring 32 is provided in the annular groove. The exposed part of the sealing ring 32 is in close contact with the inner wall of the mounting cavity 11 to prevent water from overflowing through the shell hole 12. Optionally, the sealing ring 32 and the adhesive layer 3121 are integrally formed, which can eliminate the installation step of the sealing ring 32, reduce the complexity of installation, and at the same time prevent the sealing ring 32 from falling off.

[0062] In another embodiment, the valve seat has a sealing groove at its end, and an O-ring 33 is provided in the sealing groove. Preferably, the O-ring 33 and the rubber coating layer 3121 are integrally formed, which can eliminate the installation step of the O-ring 33, reduce the cumbersome installation, and at the same time prevent the O-ring 33 from falling off.

[0063] To improve the installation stability of the connector 4, the position where the connector 4 intersects with the shell hole 12 is fixed by welding.

[0064] Based on the above embodiments, the connector 4 includes an inlet connector 4 and an outlet connector 4, and the water passage 31 includes an inlet channel and an outlet channel. Further, the inlet connector 4 includes a cold water connector 42 and a hot water connector 43, the inlet channel includes a cold water channel 313 and a hot water channel 314, and the outlet channel is a mixing water channel 315.

[0065] In addition, to improve the installation stability of the valve core, the top of the valve seat 3 is provided with a valve core mounting groove 5, such as... Figures 1 to 6 The first embodiment provided, and, as Figures 13 to 18 In the third embodiment provided, or, the space at the top of the valve seat 3 where the mounting cavity 11 is located forms the valve core mounting groove 5, as shown... Figures 7 to 12 The second embodiment provided, and, as Figures 19 to 24 The fourth implementation method provided.

[0066] The valve seat 3 structure provided by this utility model adopts the method of covering the interface 312 with a rubber layer 3121, so that the rubber layer 3121 and the valve seat 3 are integrated. This can avoid the problem of the sealing ring 32 shifting when the connector 4 is inserted, improve the sealing performance and sealing reliability, and also reduce the complexity of assembly. While increasing the assembly speed, it also improves the yield rate.
