[0053] Please refer to Figure 1 - Figure 17 , an embodiment of the present application provides a ball valve 100 with an unrestricted installation direction, and the ball valve 100 includes: a handle 10, a valve body 20, a valve stem 30, a valve core 40, an upper valve core seat 51 and a lower valve core seat 52.

[0054] Among them, the valve stem 30 is arranged inside the valve body 20 and is connected to the handle 10. The valve core 40 is integrally formed at one end of the valve stem 30 away from the handle 10, and is formed with a first communication hole 41 penetrating along the first direction F1. The upper valve core seat 51 and the lower valve core seat 52 are inserted into the valve body 20 along the second direction F2 coinciding with the axis of the valve stem 30. The upper valve core seat 51 and the lower valve core seat 52 are spliced to form a ball pair space 53. The valve core 40 is restricted within the ball pair space 53 and can rotate around the second direction F2. The upper valve core seat 51 and the lower valve core seat 52 are spliced to form a second communication hole 54 penetrating along the first direction F1, and a third communication hole 55 penetrating along the third direction F3 perpendicular to the first direction F1 and the second direction F2. When the valve core 40 is rotated around the second direction F2, the first communication hole 41 can be communicated with either the second communication hole 54 or the third communication hole 55. Thus, during installation, a choice can be made between the second communication hole 54 and the third communication hole 55, and one of them can be connected to the external fluid channel. In the case of a tee, two channels can further be connected to the external fluid channel, thereby improving the flexibility and adaptability of the installation of the ball valve 100.

[0055] More preferably, the ball valve 100 further includes: a connecting member 56 and a flow blocking member 57.

[0056] Among them, the connecting member 56 is arranged in either the second communication hole 54 or the third communication hole 55. The flow blocking member 57 is arranged in the other of the second communication hole 54 or the third communication hole 55.

[0057] Among them, by arranging the connecting member 56 in the second communication hole 54 or the third communication hole 55, the fluid flow path can be flexibly selected. When the first communication hole 41 is communicated with the hole provided with the connecting member 56, the fluid can pass through to achieve the flow in a specific direction. The flow blocking member 57 is arranged in the other hole to ensure that this path is blocked, thereby avoiding the fluid from flowing through the undesired path.

[0058] More preferably, in this embodiment, first installation grooves 541 and second installation grooves 542 are respectively formed at both ends of the second communication hole 54. The two connecting members 56 are respectively embedded in the first installation groove 541 and the second installation groove 542. When observed along the first direction F1, the two connecting members 56 are communicated with the first communication hole 41. Third installation grooves 551 and fourth installation grooves 552 are respectively formed in the two holes of the third communication hole 55. The two flow blocking members 57 are respectively embedded in the third installation groove 551 and the fourth installation groove 552. When observed along the third direction F3, the two flow blocking members 57 completely cover the third communication hole 55.

[0059] Preferably, in another embodiment, first mounting grooves 541 and second mounting grooves 542 are respectively formed at two ends of the second communication hole 54. Two of the flow blocking members 57 are respectively embedded in the first mounting groove 541 and the second mounting groove 542. When observed along the first direction F1, the two flow blocking members 57 completely cover the second communication hole 54. Third mounting grooves 551 and fourth mounting grooves 552 are respectively formed at two holes of the third communication hole 55. Two of the communication members 56 are respectively embedded in the third mounting groove 551 and the fourth mounting groove 552.

[0061] Wherein, the first preloading member 61 is arranged on a side of the upper valve seat 51 close to the handle 10 and is completely attached to a surface of the upper valve seat 51 close to the handle 10. By providing the first preloading member 61 and making it completely attached to the upper valve seat 51, the sealing performance between the valve core 40 and the valve core seat 40 can be effectively improved. The preloading member provides a certain pressure, ensuring the close contact between the valve core 40 and the valve core seat 40, thereby preventing fluid leakage and ensuring the sealing reliability of the ball valve 100 when installed in different directions.

[0062] Preferably, the ball valve 100 further includes: a second preloading member 62.

[0063] Wherein, a plurality of second preloading members 62 are stacked on a side of the first preloading member 61 close to the handle 10. When observed along the first direction F1, a surface of the second preloading member 62 adjacent to the first preloading member 61 is not completely attached, and adjacent second preloading members 62 are not completely attached. The stacked arrangement of the second preloading members 62 is not completely attached, forming a plurality of tiny gaps. These gaps can generate tiny elastic deformations when the ball valve 100 is subjected to pressure changes, thereby dynamically adjusting the pressure distribution between the preloading members and enhancing the sealing effect.

[0064] Preferably, the valve body 20 includes: a main body portion 21.

[0065] Wherein, a first chamber 211, a second chamber 212, and a third chamber 213 are formed by hollowing out the inside of the main body portion 21. Wherein, the upper valve seat 51, the lower valve seat 52, and the valve core 40 are arranged in the first chamber 211. The second chamber 212 communicates with one end of the first chamber 211 and the outside, and the third chamber 213 communicates with the other end of the first chamber 211 and the outside.

[0066] Preferably, a fifth mounting groove 2111 recessed along the second direction F2 is formed at the bottom of the first chamber 211. The lower valve element seat 52 is located on the side of the fifth mounting groove 2111 close to the handle 10. The valve stem 30 penetrates through the upper valve element seat 51 and the lower valve element seat 52 along the second direction F2 and extends into the fifth mounting groove 2111.

[0067] Preferably, the valve body 20 further includes: a threaded portion 22.

[0068] Wherein, the threaded portion 22 is integrally formed at one end of the main body portion 21 close to the handle 10. A fourth chamber 221 is formed by hollowing out the interior of the threaded portion 22. The valve stem 30 is inserted into the first chamber 211 after passing through the fourth chamber 221 along the second direction F2.

[0069] Preferably, the ball valve 100 further includes: a limit nut 70 and a locking member 80.

[0070] Wherein, the limit nut 70 is provided on the side of the main body portion 21 close to the handle 10 and is in threaded cooperation with the threaded portion 22. The locking member 80 is provided on the side of the second pre-tightening member 62 close to the handle 10 and is connected to the handle 10. The valve stem 30 penetrates through the locking member 80 and is connected to the handle 10.

[0071] Thereby, by providing a second communication hole 54 formed by splicing the upper valve element seat 51 and the lower valve element seat 52 and penetrating along the first direction F1, and a third communication hole 55 penetrating along a third direction F3 perpendicular to the first direction F1 and the second direction F2, when the valve element 40 is rotated around the second direction F2, the first communication hole 41 can be communicated with either the second communication hole 54 or the third communication hole 55. Thus, when installing, a choice can be made between the second communication hole 54 and the third communication hole 55, and one of them can be connected to the external fluid channel. In the case of a tee, two channels can further be connected to the external fluid channel, thereby improving the installation flexibility and adaptability of the ball valve 100.

[0072] The above-described embodiments merely represent several embodiments of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
