Figure 2 A cross-sectional structure schematic diagram of the ball valve provided by the embodiment is shown. Figure 3 An explosion structure schematic diagram of the ball valve provided by the embodiment is shown. Figures 1-3As shown, the embodiment provides a ball valve, which comprises a valve body 1, a valve seat 3 and a valve ball 2, the valve body 1 has a first channel 101 for fluid medium to flow through, the valve seat 3 is arranged in the valve body 1 and sealingly cooperates with the valve ball 2, the valve seat 3 has a first through hole 31, the valve ball 2 has a second channel 201, the valve ball 2 is rotationally arranged in the first channel 101 and can cooperate with the valve seat 3 to selectively open and close the first channel 101. In use, when the valve ball 2 is rotated to the position where the second channel 201 intersects with the first through hole 31 of the valve seat 3, the ball valve is in an open state; when the valve ball 2 is rotated to the position where the second channel 201 is misaligned with the first through hole 31 of the valve seat 3, the ball valve is in a closed state. In addition, as the valve ball 2 rotates, the range of intersection between the second channel 201 and the first through hole 31 of the valve seat 3 also changes, and the flow of the fluid medium through the first channel 101 also changes, thereby achieving control of the flow of the pipeline.

[0049] The ball valve in the related art usually has the problems of difficult installation of the valve ball and poor aesthetics in use. To solve this problem, as shown in Figure 2 and Figure 3 As shown, the embodiment provides a ball valve, which comprises a valve body 1, a valve seat 3 and a valve ball 2, the valve body 1 has a first channel 101 for fluid medium to flow through, the valve seat 3 is arranged in the valve body 1 and sealingly cooperates with the valve ball 2, the valve seat 3 has a first through hole 31, the valve ball 2 has a second channel 201, the valve ball 2 is rotationally arranged in the first channel 101 and can cooperate with the valve seat 3 to selectively open and close the first channel 101. In use, when the valve ball 2 is rotated to the position where the second channel 201 intersects with the first through hole 31 of the valve seat 3, the ball valve is in an open state; when the valve ball 2 is rotated to the position where the second channel 201 is misaligned with the first through hole 31 of the valve seat 3, the ball valve is in a closed state. In addition, as the valve ball 2 rotates, the range of intersection between the second channel 201 and the first through hole 31 of the valve seat 3 also changes, and the flow of the fluid medium through the first channel 101 also changes, thereby achieving control of the flow of the pipeline.

[0050] The ball valve provided by the embodiment, by arranging the first joint 111 and the second joint 5, is used to realize connection with the external pipeline, thereby ensuring the flow of the fluid medium in the pipeline; by pre-embedding part of the valve body 1 in the installation wall 1000, the aesthetics of the entire ball valve after installation can be ensured, and the user experience can be improved; by arranging the mounting hole 121 on the side wall of the valve body 1, the assembly of the valve ball 2 and the valve body 1 can be facilitated, the assembly difficulty can be reduced, and the assembly efficiency can be improved; by detachably connecting the second joint 5 to the mounting hole 121, a second joint 5 with a suitable length can be selected according to the installation space and length of the corresponding pipeline, so as to improve the universality of the ball valve, and interference between the valve ball 2 and the second joint 5 during installation can be avoided.

[0051] To realize the connection between the ball valve and the external pipeline, the first joint 111 is threadedly connected with the corresponding external pipeline; and the second joint 5 is threadedly connected with the corresponding external pipeline. The threaded connection has the advantages of simple structure, easy disassembly and assembly, and tight connection.

[0052] Optionally, the axis direction of the first joint 111 is arranged at an angle with the axis direction of the first channel 101, and the axis direction of the second joint 5 is arranged at an angle with the axis direction of the first channel 101. This design can make the first joint 111 and the second joint 5 adapt to the corresponding external pipeline, and realize the stable connection of the ball valve and the external pipeline. In this embodiment, the angle between the axis direction of the first joint 111 and the axis direction of the first channel 101 is 90°, and the angle between the axis direction of the second joint 5 and the axis direction of the first channel 101 is 90°, that is, the first joint 111 and the second joint 5 are arranged in parallel to adapt to the corresponding external pipeline. Of course, the embodiment does not limit the angle between the axis direction of the first joint 111 and the axis direction of the first channel 101 and the angle between the axis direction of the second joint 5 and the axis direction of the first channel 101, and the two can be arranged in parallel or not in parallel. The designer can adjust the above angles according to the actual installation requirements.

[0053] As shown in Figure 2 and Figure 3 , the valve ball 2 is provided with a second through hole 21 at one end of the embedded section, the first channel 101 and the second channel 201 are communicated with the second through hole 21, and the valve ball 2 rotates to communicate or cut off the passage between the second channel 201 and the first through hole 31. Taking the first joint 111 as the inlet and the second joint 5 as the outlet as an example, when the valve ball 2 rotates to the communication position (the second channel 201 communicates with the first through hole 31), the fluid medium in the upstream pipeline can flow to the downstream pipeline from the second joint 5 in sequence through the first joint 111, the first channel 101, the second through hole 21, the second channel 201 and the first through hole 31; when the valve ball 2 rotates to the cut-off position (the second channel 201 is staggered with the first through hole 31), the fluid medium in the external pipeline cannot pass through the ball valve. It can be understood that when the second channel 201 is opposite to the first through hole 31, the flow of the fluid medium passing through the ball valve is the largest; when the second channel 201 is completely staggered with the first through hole 31, the ball valve is in the closed state, that is, the valve ball 2 is in the cut-off position.

[0054] Optionally, the valve seat 3 is a ring-shaped rubber pad, which can tightly fit with the valve ball 2 by deforming itself to realize the sealing resistance of the two, and the valve seat 3 made of rubber material can also reduce the wear between the two when the valve ball 2 rotates, thereby prolonging the service life of the ball valve. In this embodiment, the number of valve seats 3 is two, and the two valve seats 3 are respectively located on both sides of the valve ball 2 and are in sealing fit with the valve ball 2. This design can ensure the uniformity of the force on the valve seat 3, thereby realizing the good sealing effect between the valve seat 3 and the valve ball 2.

[0055] As shown in Figure 2As shown, in the embodiment, the inner wall of the valve body 1 is provided with a first accommodating groove 123 for partially accommodating one of the valve seats 3; the side of the second joint 5 facing the valve ball 2 is provided with a second accommodating groove 51 for partially accommodating the other valve seat 3, so as to ensure the stable installation of the two valve seats 3 and avoid displacement of the valve seats 3 during use.

[0056] Figure 4 A structural schematic view of the valve stem 41 provided by the embodiment is shown. Figure 5 A structural schematic view of the valve ball 2 provided by the embodiment is shown. As shown in the figure, Figures 4-5 and in combination with Figure 2 , Figure 3 As shown, the ball valve further comprises an adjusting assembly 4, and the side of the valve body 1 away from the embedded section is further provided with a through hole 124; the adjusting assembly 4 comprises a valve stem 41, one end of the valve stem 41 passes through the through hole 124 and is connected with the valve ball 2, and rotating the valve stem 41 can drive the valve ball 2 to rotate, so as to open or close the first passage 101. Optionally, the valve stem 41 is inserted into the valve ball 2 in a fitting manner, so as to ensure that the valve ball 2 can rotate synchronously with the valve stem 41. Specifically, in the embodiment, the valve stem 41 is provided with an insertion end 411, and the valve ball 2 is provided with a first insertion groove 22 matched with the insertion end 411. In other embodiments, the insertion end 411 can also be arranged on the valve ball 2, and the first insertion groove 22 can be arranged on the valve stem 41, and the same effect can also be achieved.

[0057] As shown in the figure, Figure 3 The side of the valve body 1 away from the embedded section is provided with a convex neck 13, and one end of the valve stem 41 passes through the convex neck 13 and the through hole 124 in sequence and is connected with the valve ball 2. The arrangement of the convex neck 13 can improve the installation stability of the valve stem 41, and thus ensure the use performance of the entire ball valve. Optionally, a first sealing member 131 is further arranged between the valve stem 41 and the convex neck 13, so as to ensure the sealing between the two, thereby avoiding leakage of the fluid medium in the first passage 101 from between the valve stem 41 and the convex neck 13.

[0058] Optionally, the adjusting assembly 4 further comprises a handle 42 connected to the other end of the valve stem 41. By arranging the handle 42, the operator can hold the handle 42 to rotate the valve stem 41, thereby improving the convenience of operation of the operator. In the embodiment, the handle 42 is provided with a second insertion groove 421, and the end of the valve stem 41 away from the valve ball 2 is inserted into the second insertion groove 421, thereby facilitating the quick disassembly and assembly between the handle 42 and the valve stem 41. In the embodiment, the cross-sectional shape of the second insertion groove 421 is non-circular, and the cross-sectional shape of the end of the valve stem 41 is matched with that of the second insertion groove 421, so as to ensure that the valve stem 41 can rotate synchronously with the handle 42.

[0059] Continuing as shown in the figure, Figure 2 and Figure 3As shown, in the embodiment, the valve body 1 is an integral structure to ensure the integrity of the entire valve body 1, and meanwhile, the leakage points on the valve body 1 can be reduced, thereby improving the safety of the ball valve.

[0060] Optionally, the pre-embedded section is further provided with a machining hole 122 coaxial with the first channel 101, and the machining hole 122 is plugged with a sealing plug 6. By providing the machining hole 122, the operator can conveniently machine the first channel 101, and the machining efficiency of the ball valve is improved. The sealing plug 6 is a sealing structure commonly used in the prior art, and the specific structure and mounting mode of the sealing plug 6 will not be described herein.

[0061] Embodiment Two

[0062] The embodiment provides a ball valve, and the specific structure of the ball valve is substantially the same as that of the ball valve in Embodiment One, and the difference lies in that the structure of the valve body 1 is different.

[0063] Figure 6 A structure schematic diagram of the ball valve provided in the embodiment is shown. Figure 7 A sectional structure schematic diagram of the ball valve provided in the embodiment is shown. Figures 6-7 As shown, in the embodiment, the valve body 1 includes a base 11 and a valve main body 12 detachably connected to the base 11, the base 11 forms a pre-embedded section, and the mounting hole 121 is arranged on the side wall of the valve main body 12. In the embodiment, the medium flow passage in the base 11 and the medium flow passage in the valve main body 12 are connected to form the first channel 101, and compared with the longer first channel 101, the efficiency and convenience of the operator in machining the medium flow passage in the base 11 and the medium flow passage in the valve main body 12 are higher.

[0064] Optionally, the valve main body 12 is threadedly connected to the base 11, and the structure is simple, the connection is stable, and the disassembly and assembly are convenient. It can be understood that, since the valve main body 12 and the base 11 are threadedly connected, when the two are screwed to the fixed position, the first joint 111 and the second joint 5 can be not parallel, which causes the ball valve to be unable to be connected to the external pipeline. Therefore, those skilled in the art can connect the valve main body 12 and the base 11 in other ways according to actual installation requirements, as long as the sealing property between the two is ensured to avoid the leakage of the internal fluid medium. Exemplarily, the valve main body 12 is inserted and fitted in the base 11, and at least one second sealing member is arranged between the valve main body 12 and the base 11.

[0065] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
