[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, a three-way ball valve comprises a ball valve base 1, and three side surfaces of the ball valve base 1 are sequentially provided with a first connection port 11, a second connection port 12 and a third connection port 13;

[0025] A fixing block 2, which is arranged on the upper end of the ball valve base 1;

[0026] The handle 4 is detachably connected to the fixed block 2. A sealing ring 5 and a pressing block 6 are arranged between the handle 4 and the fixed block 2. The pressing block 6 is arranged above the sealing ring 5. The sealing ring 5 is located between the handle 4 and the fixed block 2, and plays a key sealing role. This design can ensure that the first connection port 11, the second connection port 12 and the third connection port 13 have good sealing performance when the ball valve is closed, so as to prevent medium leakage. The detachable connection design between the handle 4 and the fixed block 2 makes the maintenance and replacement of the ball valve more convenient. When the sealing ring 5 is worn or needs to be replaced, the handle 4 can be easily disassembled, the new sealing ring 5 can be replaced, and then the handle 4 can be reinstalled without disassembling or replacing the entire ball valve. The pressing block 6 is arranged above the sealing ring 5, which can ensure that the sealing ring 5 is subjected to sufficient pressure when the ball valve is closed, so as to maintain its sealing performance. This design can prevent leakage problems caused by loose sealing ring 5 or insufficient pressure, and improve the safety of the ball valve.

[0027] like Figure 1 As shown, a connecting piece 3 is provided above the handle 4, and an annular groove 31 is provided on the connecting piece 3; the annular groove 31 on the connecting piece 3 above the handle 4 plays multiple roles in sealing, fixing, positioning and shockproofing in the three-way ball valve, and is an indispensable part of the valve system.

[0028] like Figure 1 and Figure 2 As shown, the handle 4 includes an inclined surface 42 and a rubber sleeve 41; the inclined surface 42 of the handle 4 is designed mainly to provide a better grip angle and comfort. The inclined surface 42 makes the handle 4 more in line with the natural gripping posture of the human hand, reduces hand fatigue, and increases grip stability. During operation, the inclined surface 42 design allows the operator to complete the rotation or push-pull and other actions of the handle 4 more labor-saving and conveniently.

[0029] Rubber sleeve 41: The functions of the rubber sleeve 41 are mainly reflected in the following aspects:

[0030] Anti-slip: The rubber material has a high friction coefficient, which can effectively prevent the handle 4 from sliding during use, ensuring the stability and safety of the operator.

[0031] Wear resistance: The rubber material has good wear resistance and can resist wear during long-term use, thereby extending the service life of the handle 4.

[0032] Sweat absorption: The rubber sleeve 41 can absorb sweat from the hands, keep the handle 4 dry and comfortable, and reduce the slipping phenomenon caused by sweat.

[0033] Buffering: Rubber material has a certain elasticity and can play a buffering role, reducing the impact of impact force on the hands during operation.

[0034] Insulation: Rubber is an insulator that can isolate electric current and protect operators from electric shock.

[0035] like Figure 1 and Figure 2 As shown, the angle between the inclined plane 42 and the horizontal plane is between 30-60 degrees, and the optimal angle between the inclined plane 42 and the horizontal plane is 45 degrees; 45 degrees is considered to be one of the most ergonomic angles. This angle design makes the handle 4 more in line with the natural gripping posture of the human hand, so that the operator can reduce hand fatigue during long-term use and improve the comfort of operation.

[0036] like Figure 1 As shown, the handle 4 and the fixing block 2 are detachably fixedly connected by fastening bolts; the detachable fixed connection between the handle 4 and the fixing block 2 by fastening bolts is not only convenient for installation and disassembly, good stability, and easy maintenance, but also has excellent sealing performance and strong adaptability. These advantages make the three-way ball valve more reliable, efficient and convenient in practical applications.

[0037] like Figure 1 and Figure 2 As shown, the first connection port 11, the second connection port 12 and the third connection port 13 are all set to be circular; the circular pipe cross-section has the smallest resistance when the fluid flows, because the circular cross-section can make the fluid flow more uniform, reduce turbulence and resistance loss. In the three-way ball valve, this design helps to ensure that the fluid can pass through each connection port smoothly, reduce energy consumption, and improve system efficiency; the circular cross-section has higher structural strength when under pressure. Since the three-way ball valve needs to withstand a certain fluid pressure in the pipeline system, the use of a circular connection port can better ensure the structural stability and safety of the valve; the circular cross-section has higher feasibility and efficiency in the processing and manufacturing process. The circular pipe cross-section can be processed by simple cutting, milling and other processes, and the processing accuracy is high, which can meet the requirements of high-precision connection.

[0038] like Figure 1 As shown, the clamping block 6 slightly protrudes from the sealing ring 5; when the clamping block 6 slightly protrudes from the sealing ring 5, it can ensure that the sealing ring 5 is subjected to sufficient pressure when the ball valve is closed, so that it fits more closely on the sealing surface of the valve. This design helps to reduce the possibility of leakage and improve the sealing performance of the ball valve; during the use of the valve, the sealing ring 5 may sometimes shift due to factors such as fluid pressure, temperature changes or vibration. The design that the clamping block 6 slightly protrudes from the sealing ring 5 can provide a stable support and constraint to prevent the sealing ring 5 from moving unnecessarily, thereby maintaining its sealing performance.

[0039] In the present invention, firstly, the first connection port 11 , the second connection port 12 and the third connection port 13 are respectively connected and fixed to the corresponding pipes, and then the handle 4 is rotated to complete the adjustment of the ball valve.

[0040] To sum up, the three-way ball valve is provided with a handle 4, and the handle 4 is detachably connected to the fixed block 2, so that the operation of the ball valve is more flexible and it is convenient to replace worn parts; a sealing ring 5 and a clamping block 6 are provided between the handle 4 and the fixed block 2, which can improve the sealing performance of the ball valve, and the clamping block 6 is provided above the sealing ring 5, and the sealing ring 5 is clamped on the fixed block 2, which further improves the sealing performance of the ball valve.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
