[0049] like Figure 1-4 , a valve body structure, comprising: a valve body shell 1 and a valve core 2;

[0050] The valve body shell 1 includes, from top to bottom, a valve body upper shell 11 and a valve body lower shell 12;

[0051] The valve body upper shell 11 is provided with an upper shell hollow cavity 111; the valve body lower shell 12 is provided with a lower shell hollow cavity 121;

[0052] One of the upper half of the valve core 2 and the upper shell hollow cavity 111 is provided with a first internal thread structure 201, and the other is provided with a first external thread structure 202. The first internal thread structure 201 cooperates with the first external thread structure 202 to make the upper half of the valve core 2 detachably connected to the valve body upper shell 11, and the upper half of the valve core 2 is located in the upper shell hollow cavity 111;

[0053] One of the lower half of the valve core 2 and the lower shell hollow cavity 121 is provided with a second internal thread structure 301, and the other is provided with a second external thread structure 302. The second internal thread structure 301 cooperates with the second external thread structure 302 to allow the lower shell hollow cavity 121 to be detachably installed on the valve core 2; the lower half of the valve core 2 is located in the lower shell hollow cavity 121.

[0054] The present solution provides a valve body structure, wherein the valve body shell 1 can be divided into a valve body upper shell 11 and a valve body lower shell 12, which can be threadedly matched with different upper and lower positions of the valve core 2 through threaded structures at different positions, so that the valve body structure can be installed and processed separately, so that the worn parts can be replaced during daily use, and the processing loss of the valve body upper shell 11, the valve body lower shell 12 and the valve core 2 is reduced, thereby solving the problems of high replacement cost and high waste residue during processing of the existing valve body structure.

[0055] Specifically, the valve body shell 1 can be divided into: a valve body upper shell 11 located relatively above and a valve body lower shell 12 located relatively below; the valve body upper shell 11 is provided with an upper shell hollow cavity 111, and the upper shell hollow cavity 111 can be connected to the upper half of the valve core 2, specifically, the upper shell hollow cavity 111 can be provided with a first internal thread structure 201 (or a first external thread structure 202), and the upper half of the valve core 2 can be provided with a first external thread structure 202 (or a first internal thread structure 201), and the upper half of the valve core 2 extends into the upper shell hollow cavity 111, and the upper half of the valve core 2 is threadedly matched with the valve body upper shell 11, so that the upper half of the valve core 2 and the valve body upper shell 11 can be assembled into one; similarly The lower shell 12 of the valve body is provided with a lower shell hollow cavity 121, and the lower shell hollow cavity 121 can be provided with a second internal thread structure 301 (or a second external thread structure 302), and the lower half of the valve core 2 can be provided with a second external thread structure 302 (or a second internal thread structure 301), and the lower half of the valve core 2 extends into the lower shell hollow cavity 121, and the lower half of the valve core 2 is threadedly matched with the lower shell 12 of the valve body, so that the lower half of the valve core 2 and the lower shell 12 of the valve body can be assembled into one body; in this way, the valve body outer shell 1 of the present scheme is divided into two parts to be connected with the upper and lower parts of the valve core 2 respectively, and any one of the valve body upper shell 11, the valve body lower shell 12 and the valve core 2 during use is When the valve body is damaged, it can be directly replaced by keeping the new replacement part in threaded cooperation with the original one, without directly replacing the entire valve body structure, thereby reducing the replacement cost of the valve body structure; at the same time, the valve body structure of this scheme saves more materials and is more convenient to process than the conventional valve body structure; during processing, the valve body upper shell 11, the valve body lower shell 12 and the valve core 2 can be processed separately, especially for the valve body upper shell 11 and the valve body lower shell 12, the valve body upper shell 11 and the valve body lower shell 12 only need to be processed into a through structure, and the corresponding internal thread structure or external thread structure can be directly processed; therefore, the valve body shell 1 of this scheme does not need to be processed like the conventional valve body structure The shape of the valve core 2 needs to be processed once inside the valve body shell 1. This processing method will lead to a lot of processing waste and complicated processing steps. However, the valve core 2 of this solution is processed separately. The internal processing of the valve core 2 does not need to be formed once inside the valve body shell 1 like traditional processing. Instead, it only needs to process the internal thread structure or external thread structure on the valve core 2. Therefore, the processing steps will not be too complicated. Furthermore, the processing of the valve core 2 is concentrated on the valve core 2 itself, rather than the traditional valve body structure as a whole. Therefore, the processing loss is only on the valve core 2 itself, rather than the valve body structure as a whole, so the processing waste residue is far less than the traditional valve body overall processing. In this way, this solution solves the problems of high replacement cost of the existing valve body structure and high processing waste residue.

[0056] Optimally, the valve core 2 comprises: an upper core component 21 and a lower core component 22;

[0057] The lower core component 22 contacts or is installed below the upper core component 21;

[0058] The upper core component 21 is provided with the first internal thread structure 201 or the first external thread structure 202 , and the second internal thread structure 301 or the second external thread structure 302 ;

[0059] The lower core component 22 is provided with the second internal thread structure 301 or the second external thread structure 302 .

[0060] The valve core 2 of the present solution can be an integrated structure; and in the optimal embodiment, the present solution can also be divided into: an upper core component 21 located relatively above and a lower core component 22 located relatively below, the upper core component 21 and the lower core component 22 are respectively provided with a second internal thread structure 301 or the second external thread structure 302; when the upper core component 21 is connected to the upper shell hollow cavity 111 through its first internal thread structure 201 or the first external thread structure 202, the lower shell hollow cavity 121 is connected to the lower part of the upper core component 21 through the second internal thread structure 301 and the second external thread structure 302, and the lower core component 22 is connected to the lower part of the upper core component 21 through its second internal thread structure 301 and the second external thread structure 302. After 01 and the second external thread structure 302 are connected to the hollow cavity 121 of the lower shell, the lower core component 22 can be in contact with or installed under the upper core component 21, thereby completing the complete assembly of the valve core 2; and because the upper core component 21 and the lower core component 22 can be installed separately, the pipeline channels inside the valve core 2 can be processed separately, that is, the preset pipelines are processed in the upper core component 21 and the lower core component 22 respectively, and the pipeline channels inside the valve core 2 are processed separately on the upper core component 21 and the lower core component 22, and it is not necessary to process the valve core 2 as a whole. Therefore, the pipeline structure of the valve core 2 can be designed to be more complex, with fewer processing steps and less waste.

[0061] The internal passages of the upper core segment 21 and / or the lower core segment 22 can be determined according to actual needs. In the best embodiment;

[0062] Optimally, the lower core segment 22 is provided with an input channel 221 and an output channel 222; the upper core segment 21 is provided with an upper core channel 211 between the bottom and the side;

[0063] The input channel 221, the upper core channel 211, the lower shell hollow cavity 121 and the output channel 222 are connected in sequence.

[0064] When the lower core segment 22 contacts or is installed below the upper core segment 21, the input channel 221 of the lower core segment 22 is connected to the upper core channel 211 of the upper core segment 21; the upper core channel 211 extends from the bottom of the upper core segment 21 to the side, so that after the fluid is input to the bottom of the upper core channel 211, it can be output to the lower shell hollow cavity 121, and then transferred from the lower shell hollow cavity 121 to the output channel 222, thereby realizing the fluid circulation of the conventional valve body; and the valve core 2 of this scheme can be adjusted according to the needs Replaced with the well-known valve core 2, the switch structure of the valve core 2 can be set on the upper core component 21 and / or the lower core component 22 as needed. For example, an adjustable adjustment end 81 is set on the upper core channel 211. When the valve core 2 is in an open state, the opening on the side of the upper core component 21 is exposed, so that the upper core channel 211 is connected to the hollow cavity 121 of the lower shell; when the valve core 2 is in a closed state, the opening on the side of the upper core component 21 is blocked, so that the upper core channel 211 is not connected to the hollow cavity 121 of the lower shell.

[0065] It can be optimized to further include: a lower core sealing ring 3;

[0066] One of the inner wall of the lower shell hollow cavity 121 or the outer wall of the lower core component 22 is provided with a lower core sealing groove 31, and the lower core sealing ring 3 is arranged in the lower core sealing groove 31, and the other of the two is against the notch of the lower core sealing groove 31 to compact the lower core sealing ring 3.

[0067] The lower core sealing groove 31 is arranged between the inner wall of the lower shell hollow cavity 121 or the outer wall of the lower core component 22. The lower core sealing groove 31 can be used to install the lower core sealing ring 3. The lower core sealing ring 3 is against the inner wall of the lower core sealing groove 31 and is limited to the lower core sealing groove 31; for some embodiments, the inner ring of the lower core sealing ring 3 is elastic and can be elastically pressed against the inner wall of the lower core sealing groove 31; for some embodiments, the notch of the lower core sealing groove 31 is horizontally oriented, and the inner wall of the lower shell hollow cavity 121 or the outer wall of the lower core component 22 horizontally presses the notch of the lower core sealing groove 31, thereby compacting the lower core sealing ring 3; for some embodiments, the lower core sealing ring 3 can be vertically placed in the lower core sealing groove 31 with the notch facing upward, and the lower shell hollow cavity 121 or the lower core component 22 vertically presses the notch of the lower core sealing groove 31, thereby vertically compacting the lower core sealing ring 3.

[0068] In the most preferred embodiment, the upper shell hollow cavity 111 is provided with the first internal thread structure 201, and the upper core component 21 is provided with the first external thread structure 202;

[0069] The lower shell hollow cavity 121 is provided with the second internal thread structure 301 at two arbitrary height positions respectively, and the upper core component 21 is further provided with the second external thread structure 302 below the first external thread structure 202 ; the lower core component 22 is provided with the second external thread structure 302 .

[0070] In this embodiment, the upper core sub-component 21 and the lower core sub-component 22 are only provided with external thread structures, which are most convenient to process, with the least waste generated, and no internal thread structure is required, and processing can be directly performed on the outer wall; similarly, the valve body upper shell 11 and the valve body lower shell 12 only need to be processed with internal thread structures at the upper and lower positions of the inner wall, which is most convenient to process and also has the least processing waste. At the same time, the second internal thread structure 301 is set at any two height positions of the lower shell hollow cavity 121, and the distance between the valve body upper shell 11 and the valve body lower shell 12 can be determined by the position of the second external thread structure 302 of the upper core sub-component 21, so the height adjustable range of the valve body outer shell 1 of this solution is larger.

[0071] Optimally, the first internal thread structure 201 is arranged at the lower end of the upper shell hollow cavity 111; the second internal thread structure 301 is respectively arranged at the upper and lower ends of the lower shell hollow cavity 121; the lower end of the valve body upper shell 11 abuts against the upper end of the valve body lower shell 12; the lower end of the valve body lower shell 12 abuts against the lower core component 22.

[0072] According to this structure, the gap between the valve body upper shell 11 and the valve body lower shell 12 of this scheme is the smallest, the connection tightness is the highest, and the gap is the smallest. The valve body upper shell 11, the valve body lower shell 12, the upper core component 21 and the lower core component 22 are seamlessly connected into one. The valve body structure has a high degree of integration, the most coordinated appearance, and has the advantage of being split and detachable.

[0073] It can be further optimized to further include: an external connection mechanism 4;

[0077] This solution uses a split installation structure of the valve body shell 1 and the valve core 2, and also uses internal and external thread structures similar to the above two to install external accessories; the external accessories are commonly used mechanisms in the actual application scenarios of the valve body, such as pumps, water pipes, filters and other water-using equipment or their accessories. In general, the external mechanism 4 can be used as an installation station for external accessories, which can limit the external accessories to the outer wall of the valve body shell 1. Specifically, the external sleeve 41 is provided with a locking internal thread structure 411, and the outer side wall of the valve body upper shell 11 and / or the outer side wall of the valve body lower shell 12 is provided with a locking external thread structure 412. When the outer side wall of the valve body upper shell 11 or the outer side wall of the valve body lower shell 12 is threadedly matched with the external sleeve 41, the external sleeve 41 can be limited to the outer side wall of the valve body outer shell 1, thereby limiting the external accessories to the outer side wall of the valve body outer shell 1; the valve body upper shell 11, the valve body lower shell 12, the upper core component 21 and the lower core component 22 are tightly connected to carry the external accessories on the external sleeve 41, and the threaded matching method also facilitates the disassembly and installation of external accessories.

[0078] It can be optimized to further include: a valve body mounting seat 5;

[0079] The external connection mechanism 4 further includes: an external connection screw 42;

[0080] The external screw 42 is threadedly matched with the external sleeve 41 and the valve body mounting seat 5, so that the valve body shell 1 and the valve body mounting seat 5 are connected as a whole.

[0081] The valve body mounting seat 5 can be used to extend the installation area of ​​the valve body shell 1; the external screw 42 can be directly threadedly matched with the external sleeve 41, and then threadedly matched with the valve body mounting seat 5, so that the valve body shell 1 and the valve body mounting seat 5 can be connected as one, and the fixing stability between the valve body shell 1 and the valve body mounting seat 5 is the best.

[0084] The fixing platform 6 provides a fixed position for the valve body structure, specifically, the valve groove 61 can be used to accommodate the valve body structure, and the fixing platform 6 is also installed with a valve plate pad 7 with a pad opening 71. The valve body structure only needs to preset a pad external thread structure 712 on the outer side wall of the valve body upper shell 11 or the outer side wall of the valve body lower shell 12. When the valve body upper shell 11 or the valve body lower shell 12 is threadedly engaged with the pad opening 71, the valve body outer shell 1 is limited to the valve groove 61, thereby realizing the installation of the valve body structure on the fixing platform 6. The valve body structure can be quickly and detachably installed on the fixing platform 6, which also facilitates the rapid disassembly and replacement of accessories of the valve body structure, and facilitates the daily repair and maintenance of the faucet.
