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 using a rubber-coated seal. 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

[0052] 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, and 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.

[0053] The connector 4 is made of metal, with one end being a mating end 41, and the outer periphery of the mating end 41 is covered with an adhesive coating 42. In one embodiment, to improve the tightness of the connection between the connector 4 and the adhesive coating 42, the outer periphery of the mating end 41 of the connector 4 is provided with a protrusion 43 or a groove, and the adhesive coating 42 covers the protrusion 43 or the groove.

[0054] 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 coating 42. In one embodiment, the adhesive coating 42 covers the end of the mating end 41 to form an end seal, thereby further improving the sealing performance. Preferably, the connector 4 is welded and fixed in the state of the end portion with the adhesive coating 42 compressed, to avoid end seal failure.

[0055] In another embodiment, the interface 312 is stepped, thereby providing reliable axial support for the connector 4 and facilitating the formation of an end seal. Alternatively, the interface 312 may have an annular groove 32 around its periphery, within which a sealing ring 33 is provided. The exposed portion of the sealing ring 33 is in close contact with the inner wall of the mounting cavity 11 to prevent water from overflowing through the shell hole 12.

[0057] 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 44 and a hot water connector 45, 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. In this case, there are three water passage holes 311, arranged in a triangular pattern at the end of the valve seat 3. The water passage holes 311 of the cold water channel 313 and the hot water channel 314 are located between the water passage hole 311 of the mixing water channel 315 and the outlet connector 4, as shown below. Figures 1 to 10 In the first and second embodiments provided, or in the case of the mixing water channel 315, the water passage 311 is located between the water passage 311 of the cold water channel 313 and the hot water channel 314 and the water outlet connector 4, as shown. Figures 11 to 20 The third and fourth implementation methods are provided.

[0058] 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 5 The first embodiment provided, and, as Figures 11 to 15 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 6 to 10 The second embodiment provided, and, as Figures 16 to 20 The fourth implementation method provided.

[0059] The valve seat 3 structure provided by this utility model adopts the method of covering the mating end 41 with rubber 42 to form an integral part with the rubber 42 and the connector 4. This can avoid the problem of the sealing ring 33 shifting when the connector 4 is inserted, improve the sealing performance and sealing reliability. In addition, it also reduces the complexity of assembly, improves the assembly speed and the yield rate.
