Description

Technical Field

[0001] This invention relates to the field of pipeline valve facilities, and specifically to a ball valve ball for liquid diversion and its adjustment method. Background Technology

[0002] In many fields such as industrial fluid transportation, building HVAC, chemical processes, and water supply and drainage, three-way valves are widely used in various pipeline systems as core control components for fluid diversion, merging, or reversal. Their basic function is to switch between a single inlet and two outlets by rotating the valve core, thus meeting the basic control requirements of the pipeline system for fluid flow direction.

[0003] Traditional three-way valves, whether plug, ball, or butterfly types, are designed solely for on / off switching. Taking the most widely used three-way ball valve as an example, its valve core is a ball with an L-shaped or T-shaped through-hole. Rotating the ball changes the alignment between the through-hole and the valve body interface, thus achieving single-inlet / single-outlet or single-inlet / double-outlet on / off control. However, this structure has a fundamental functional limitation: in single-inlet / double-outlet split mode, fluid can only flow equally from the inlet to both outlets, making it impossible to independently and continuously adjust the flow distribution ratio between the two outlets.

[0004] In practical engineering scenarios, when it is necessary to differentiate the supply flow to different areas, traditional three-way ball valves cannot achieve flow ratio adjustment and can only rely on additional flow regulating valves or bypass pipelines. This not only increases the complexity, cost and energy consumption of the system, but also reduces the system response speed due to the lag of multi-component coordinated control, and increases the difficulty of equipment investment and maintenance.

[0005] Some existing pipeline systems use a method of adding independent regulating valves after the two output branches of a three-way valve to achieve flow distribution through dual-valve regulation. However, this method requires additional installation space and control structure, resulting in low system integration. Summary of the Invention

[0006] The purpose of this invention is to provide a ball valve for liquid diversion and its adjustment method to solve the above-mentioned problems. A transversely movable valve disc is set inside the valve ball. With the cooperation of the control component and the transmission structure of the transmission frame, the flow area ratio of the two bifurcated output channels can be adjusted by simply rotating the knob. This achieves continuous flow ratio adjustment from fully closed, gradually to fully open. It solves the defects of traditional three-way ball valves that can only divert flow in equal amounts or have fixed on / off states and cannot independently adjust the flow at the two output ends, thus meeting the application requirements of more scenarios. See the following description for details.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a ball valve body for liquid diversion, comprising a valve body and a valve ball, wherein the valve ball is built into the middle of the valve body, and a valve disc is provided inside the valve ball. An operating handle for supporting the rotation of the valve ball is vertically passed through the top of the valve body, and a control component for driving the valve disc to move laterally is provided in the middle of the operating handle. The valve ball has a horizontally extending, "T"-shaped core hole in the middle. The core hole includes two horizontally connected output ends. The midpoint of the two output ends is connected forward to an input end. The valve disc is located at the intersection of the input end and the output end in the core hole. The valve disc can move horizontally between the two output ends, thereby adjusting the flow distribution of the two bifurcated output paths formed by the input end and the two output ends.

[0008] Preferably, the valve disc has a flat structure that is narrow at the front and wide at the back. A guide groove is provided on the inner top side of the valve ball. A transmission frame with a transverse sliding fit guide groove is fixed on the top side of the valve disc. The top of the valve disc expands outward along both sides to form a sealing gasket that covers the bottom opening of the guide groove, and the sealing gasket fits against the inner wall of the core hole.

[0009] Preferably, the outer walls of the valve balls on both sides of the guide groove are provided with disassembly holes, and a guide rod is provided transversely on the outer side of the transmission frame. The guide rod is clearance-fitted with the transmission frame, and both ends of the guide rod are respectively inserted into two sets of disassembly holes and threaded into the disassembly holes.

[0010] Preferably, springs are sleeved on the outside of the guide rods on both sides of the transmission frame, and the other end of the springs abuts against the inside of the guide groove. An arc-shaped receiving groove is provided on the top side of the guide groove, and a shaft hole for penetrating the valve ball is provided at the top of the receiving groove. Slots are provided on both sides of the shaft hole on the top side of the valve ball.

[0011] Preferably, the operating handle includes a vertically extending valve stem, the bottom end of which is fixed with a locking tooth for a vertically engaging connecting groove, and the top end of the valve stem is vertically connected to a synchronizing block and a stud in sequence. A knob is provided on the outside of the synchronizing block, and a nut for pressing the knob downward is installed on the outside of the stud.

[0012] Preferably, a shaft is vertically inserted inside the valve stem, the shaft is clearance-fitted with the inner wall of the valve stem, and the bottom end of the shaft passes downward along the shaft hole into the receiving groove. A rearwardly extending swing arm is fixed to the bottom end of the shaft, and a transmission pin is vertically fixed to the outer eccentric end of the swing arm. The transmission frame is a longitudinally extending rectangular frame structure, and the transmission pin is vertically inserted into the transmission frame and clearance-fitted with the transmission frame.

[0013] Preferably, a knob extends from the top of the shaft and is fixed with a toggle switch. The outer circumference of the toggle switch is evenly distributed with grooves. A brake ring is fixed to the top side of the knob. Several protrusions that engage with the grooves are distributed around the top side of the brake ring. A positioning sleeve supporting the rotation of the valve stem is installed on the top side of the valve body. A fixing ring is provided inside the positioning sleeve. A movable ring that abuts against the bottom side of the fixing ring is provided on the outside of the valve stem. A compression spring is sleeved on the outside of the valve stem below the knob. The bottom end of the compression spring abuts against the top side of the fixing ring to support the knob upwards to keep the protrusions on the top side of the brake ring locking the grooves, thereby maintaining the rotation angle of the control component and locking the valve disc in the lateral position within the core hole.

[0014] Preferably, a positioning support for mounting a positioning screw sleeve is fixed on the top side of the valve body, and a mounting support is provided on the front side of the valve body. An input hole for connecting the external input end of the core hole is longitudinally penetrated in the middle of the mounting support. Output holes are connected to the corresponding output ends on both sides of the valve body. An input flange is detachably connected to the outside of the mounting support.

[0015] Preferably, output flanges are installed on the outside of both output holes, and a sealing element is provided on the inside of the output flange. The sealing element is a transversely penetrating annular body, and the inside of the sealing element is a sealing cone surface that fits the outer circumference of the valve ball.

[0016] This invention also discloses a method for adjusting the ball of a ball valve for liquid diversion, comprising the following steps: a. Connect the liquid input end to the required diversion control to the input flange, and connect the two sets of output flanges to the two external diversion pipes respectively. Turn the knob to drive the valve stem to rotate, and use the valve stem to support the valve ball to rotate until the input end of the core hole is aligned with the input hole of the valve body. The "T"-shaped core hole connects the valve body input hole and the two output holes, and the fluid is output equally to the diversion pipes on both sides through the core hole; b. When it is necessary to adjust the fluid distribution ratio of the two diversion pipes, rotate the knob with the knob as support. The knob will drive the shaft and the bottom swing arm to rotate. Since the transmission pin at the eccentric end of the swing arm vertically enters the transmission frame of the valve disc, it will push the transmission frame to move laterally along the guide groove, thereby changing the lateral position of the valve disc. Since the valve disc is a separation structure from the input end to the output ends on both sides, by moving the valve disc laterally, the distribution ratio of the fluid entering from the input end to the output ends on both sides can be adjusted. c. During the rotation of the toggle switch, the knob is pushed upward by the compression spring, maintaining the tightness between the protrusion and the groove. This ensures that the brake ring remains locked to the toggle switch angle. The knob and valve stem are locked together by the fixed ring and the moving ring. To return the valve disc to the center, press the knob downward to release the locking support of the top protrusion of the knob to the outer groove of the toggle switch. At the same time, since the valve disc is in the offset position, the spring on the offset side is compressed. When the toggle switch is released, the spring on the compressed side pushes the valve disc back to the center. Simultaneously, the transmission frame supports the transmission pin, swing arm, shaft, and toggle switch to quickly rotate and reset. d. When the valve needs to be closed, turn the knob to rotate the valve ball so that the valve stem drives the valve ball to the rear of the core hole. At this time, the fluid input channel into the valve ball is cut off, and the valve is closed. When it is necessary to connect one of the diversion pipes separately, turn the valve ball so that the other output end of the core hole corresponds to the closed position on the rear of the valve body, so that one of the diversion pipes can be connected separately.

[0017] The beneficial effects are as follows: 1. By setting a valve disc that can move laterally in the T-shaped core hole of the valve ball, and in conjunction with the transmission structure of the control component and the transmission frame, the valve disc can be driven to move laterally at the intersection of the input end and the two output ends simply by rotating the knob, thereby adjusting the flow area ratio of the two bifurcated output paths, realizing continuous flow ratio adjustment from fully closed, gradually to fully open, solving the defect of traditional three-way ball valves that can only divide the flow equally or fix the on and off, and cannot independently adjust the flow of the two output ends, thus meeting the usage requirements of more scenarios.

[0018] 2. This application integrates the flow regulation function with the ball valve body. The core regulating components such as valve disc, guide rod, spring, and control components are all built into the inside of the valve ball. There is no need to add an independent regulating valve or bypass pipeline after the output branch, which reduces the number of parts in the pipeline system and the installation space occupied. It also avoids the control lag caused by the cooperation of multiple components, improves the system response speed, and is more practical.

[0019] 3. Rotating the knob allows for quick rotation of the valve ball, enabling switching between pipeline on / off or flow diversion modes; rotating the dial adjusts the flow ratio, and the engagement between the brake ring protrusion and the dial groove stably maintains the lateral position of the valve disc, ensuring that the flow ratio remains constant after adjustment and preventing adjustment failure due to vibration or other factors.

[0020] 4. In addition, pressing down on the knob will release the locked state after the valve disc position is adjusted. Under the reset force of the spring, the valve disc can quickly return to the center and restore the equal flow distribution state. The operation logic is clear, convenient and efficient.

[0021] 5. This application retains the on / off switching function of the traditional three-way ball valve and adds a flow ratio adjustment function. It has a compact structure, is easy to install, does not change the connection status with other accessories, and can directly replace the existing traditional three-way valve, making it more adaptable.

[0029] See Figures 1-17 As shown, the present invention provides a ball valve body for liquid diversion, including a valve body 1 and a ball valve 2. The ball valve 2 is built into the middle of the valve body 1. A valve disc 3 is provided inside the ball valve 2 to separate the input end 201a of the core hole 201 and realize flow distribution and regulation. An operating handle 4 supporting the rotation of the ball valve 2 is vertically inserted through the top of the valve body 1, and a control component 5 for driving the valve disc 3 to move laterally is provided in the middle of the operating handle 4. As the core component for power transmission of the valve disc 3 to move laterally, it realizes independent control of on / off switching and proportional adjustment, and improves the ease of operation. The valve ball 2 has a horizontally extending, "T"-shaped core hole 201 in the middle. The core hole 201 includes two horizontally connected output ends 201b, which are used to respectively guide the diverted fluid to the external pipeline. The midpoint of the two output ends 201b is connected forward to the input end 201a, which is used to receive the initial fluid to be diverted. The valve disc 3 is located at the intersection of the input end 201a and the output end 201b in the core hole 201, and the valve disc 3 can move laterally between the two output ends 201b, thereby adjusting the flow distribution of the two bifurcated output paths formed by the input end 201a and the two output ends 201b, thereby achieving any proportion of flow ratio, meeting differentiated supply needs, and changing the limitation of traditional three-way valves that can only divert the flow in equal amounts.

[0030] As an optional implementation, the valve disc 3 has a flat structure that is narrow at the front and wide at the back to reduce fluid impact resistance. At the same time, the flow rate is smoothly regulated by gradually changing the cross-sectional area. A guide groove 205 is provided on the top side of the valve ball 2. A transmission frame 301 that is laterally sliding and cooperating with the guide groove 205 is fixed on the top side of the valve disc 3. The top edge of the valve disc 3 expands outward on both sides to form a sealing gasket 304 that covers the bottom opening of the guide groove 205. The sealing gasket 304 fits against the inner wall of the core hole 201 to seal the gap between the guide groove 205 and the core hole 201, preventing fluid from leaking into the internal cavity of the valve ball 2. With this configuration, the tight fit between the sealing gasket 304 and the inner wall of the core hole 201 and the flat structure design of the valve disc 3 can reduce fluid flow energy consumption and improve regulation stability while ensuring sealing performance. The outer walls of the valve balls 2 on both sides of the guide groove 205 are provided with disassembly holes 204. A guide rod 302 is provided transversely on the outer side of the transmission frame 301. The guide rod 302 is clearance-fitted with the transmission frame 301. The two ends of the guide rod 302 are respectively inserted into two sets of disassembly holes 204 and threaded into the disassembly holes 204 to facilitate the installation of the guide rod 302 into the guide groove 205. This setting can provide guidance for the transverse movement of the valve disc 3, ensuring that the valve disc 3 slides smoothly along the preset trajectory. The threaded engagement enables the guide rod 302 to be detached and installed, which is convenient for later maintenance and replacement of internal components such as the valve disc 3 and the spring 303. Springs 303 are fitted on the outside of the guide rods 302 on both sides of the transmission frame 301. The other end of the springs 303 abuts against the inside of the guide groove 205. An arc-shaped receiving groove 206 is provided on the top side of the guide groove 205. A shaft hole 203 penetrating the valve ball 2 is provided at the top of the receiving groove 206. A retaining groove 202 is provided on both sides of the shaft hole 203 on the top side of the valve ball 2. With this configuration, the springs 303 can provide the reset power for the valve disc 3 through the elastic force, while buffering the influence of fluid pressure fluctuations on the position of the valve disc 3. The receiving groove 206 provides sufficient space for the rotation of the swing arm 502 and avoids interference with the inner wall of the valve ball 2. The operating handle 4 includes a vertically extending valve stem 401. The bottom end of the valve stem 401 is fixed with a locking tooth 404 that fits into the vertically engaging slot 202 to achieve synchronous rotation of the valve stem 401 and the valve ball 2, ensuring that the valve ball 2 rotates to switch between on / off states or flow diversion modes. The top end of the valve stem 401 is vertically connected to a synchronizing block 401b and a stud 401c. A knob 402 is provided on the outside of the synchronizing block 401b. A synchronizing groove 402a that fits the synchronizing block 401b passes through the middle of the knob 402. A nut 403 that presses down on the knob 402 is installed on the outside of the stud 401c. This arrangement makes it easy to lock the relative position of the knob 402 and the valve stem 401 by the nut 403, preventing the knob 402 from loosening, while ensuring the synchronous rotation transmission of the knob 402 and the valve stem 401. A shaft 501 is vertically inserted inside the valve stem 401. The shaft 501 is clearance-fitted with the inner wall of the valve stem 401 to ensure that the shaft 501 can rotate independently of the valve stem 401, realizing separate control of on / off and adjustment functions. The bottom end of the shaft 501 extends downward along the shaft hole 203 into the receiving groove 206. A rearwardly extending swing arm 502 is fixed to the bottom end of the shaft 501. A transmission pin 503 is vertically fixed to the outer eccentric end of the swing arm 502. The transmission frame 301 is a longitudinally extending rectangular frame structure. The transmission pin 503 is vertically inserted into the transmission frame 301 and clearance-fitted with the transmission frame 301, thereby converting the rotational motion of the shaft 501 into the lateral linear motion of the transmission frame 301, thereby driving the valve disc 3 to move laterally and realizing flow ratio adjustment. A knob 402 extends from the top of the shaft 501 and is fixed with a dial 504. The dial 504 has grooves 504a evenly distributed on its outer circumference. A brake ring 406 is fixed to the top side of the knob 402. Several protrusions 406a are distributed around the top side of the brake ring 406 to engage with the grooves 504a. Both the brake ring 406 and the protrusions 406a are made of rubber. A positioning screw sleeve 6 is installed on the top side of the valve body 1 to support the rotation of the valve stem 401. A fixing ring is provided inside the positioning screw sleeve 6. A movable ring 401a is provided on the outer side of the valve stem 401 to abut against the bottom side of the fixing ring. The movable ring 401a has ring teeth at the contact point with the fixing ring to improve the tightness of the engagement. A compression spring 405 is sleeved on the valve stem 401 below the knob 402. The bottom end of the compression spring 405 abuts against the top side of the fixing ring to support the knob 402 upwards to keep the top side protrusion 406a of the brake ring 406 locking the groove 504a, thereby maintaining the rotation angle of the control component 5 and locking the valve disc 3 in the lateral position within the core hole 201. This is to prevent the valve disc 3 from shifting due to equipment vibration or fluid impact, ensuring a constant flow ratio. At the same time, the rubber protrusion 406a can reduce wear during locking and improve the service life of the structure. In addition, the ring tooth design further enhances the locking stability of the valve stem 401 and the positioning screw sleeve 6, preventing the valve ball 2 from rotating accidentally.

[0031] A positioning support 103 for mounting a positioning screw sleeve 6 is fixed on the top side of the valve body 1, and a mounting support 104 is provided on the front side of the valve body 1. An input hole 101 for connecting the external input end 201a of the core hole 201 is longitudinally penetrated in the middle of the mounting support 104. Output holes 102 are connected to the corresponding output ends 201b on both sides of the valve body 1. An input flange 9 is detachably connected to the outside of the mounting support 104 for connecting the fluid input pipeline. Both sides of the output port 102 are equipped with output flanges 7. The output flanges 7 are used to connect the diversion output pipeline. The inner side of the output flange 7 is provided with a sealing element 8. The sealing element 8 is a transversely penetrating annular body. The inner side of the sealing element 8 is a sealing cone surface 801 that fits the outer circumference of the valve ball 2 to improve the sealing performance on both sides of the valve ball 2, thereby preventing fluid leakage at the connection between the output end 201b and the flange and ensuring the sealing reliability of the pipeline system.

[0032] This invention also discloses a method for adjusting the ball of a ball valve for liquid diversion, comprising the following steps: a. Connect the liquid input end 201a to the input flange 9, and connect the two sets of output flanges 7 to the two external diversion pipes respectively. Rotate the knob 402 to drive the valve stem 401 to rotate. Use the valve stem 401 to support the valve ball 2 to rotate until the input end 201a of the core hole 201 is aligned with the input hole 101 of the valve body 1. The "T"-shaped core hole 201 connects the input hole 101 of the valve body 1 and the two output holes 102. The fluid is output equally to the diversion pipes on both sides through the core hole 201. b. When it is necessary to adjust the fluid distribution ratio of the two side diversion pipes, rotate the dial 504 with the support of the knob 402. The dial 504 drives the shaft 501 and the bottom swing arm 502 to rotate. Since the transmission pin 503 at the eccentric end of the swing arm 502 vertically enters the transmission frame 301 of the valve disc 3, it pushes the transmission frame 301 to move laterally along the guide groove 205 to change the lateral position of the valve disc 3. Since the valve disc 3 serves as a separation structure from the input end 201a to the two output ends 201b, by moving the valve disc 3 laterally, the distribution ratio of the fluid entering from the input end 201a to the two output ends 201b can be adjusted. c. During the rotation of the toggle switch 504, the knob 402 is pushed upward by the compression spring 405, thus maintaining the tight abutment between the protrusion 406a and the groove 504a. This ensures that the brake ring 406 can always lock the angle of the toggle switch 504. The knob 402 and the valve stem 401 are locked together by the fixed ring and the movable ring 401a. When the valve disc 3 needs to be returned to the center, the knob 402 is pressed down to release the locking support of the protrusion 406a on the top side of the knob 402 against the groove 504a on the outside of the toggle switch 504. At the same time, since the valve disc 3 is in the offset position, the spring 303 on the offset side is compressed. When the locking state of the toggle switch 504 is released, the spring 303 on the compressed side pushes the valve disc 3 back to the center. Simultaneously, the transmission frame 301 supports the transmission pin 503, the swing arm 502, the shaft 501, and the toggle switch 504 to quickly rotate and reset. d. When the valve needs to be closed, turn knob 402 to rotate valve ball 2 to the rearward position of input end 201a of core hole 201 using valve stem 401. At this time, the fluid input channel into valve ball 2 is cut off, and the valve is closed. When it is necessary to connect one side of the diversion pipe separately, turn valve ball 2 to the other side of output end 201b of core hole 201 to the closed position on the rear side of valve body 1, so that one diversion pipe can be connected separately.

[0033] By setting a laterally movable valve disc 3 in the T-shaped core hole 201 of the valve ball 2, and cooperating with the transmission structure of the control component 5 and the transmission frame 301, the valve disc 3 can be driven to move laterally at the intersection of the input end 201a and the two output ends 201b simply by rotating the knob 504. This adjusts the flow area ratio of the two bifurcated output paths, realizing continuous flow ratio adjustment from fully closed, gradually to fully open. This solves the defect of traditional three-way ball valves that can only divide the flow equally or fix the on / off state and cannot independently adjust the flow of the two output ends 201b, thus meeting the usage requirements of more scenarios.

[0034] This application integrates the flow regulation function with the ball valve body. The core regulating components such as valve disc 3, guide rod 302, spring 303, and control component 5 are all built into the ball valve 2. There is no need to add an independent regulating valve or bypass pipeline after the output branch, which reduces the number of parts and installation space occupied in the pipeline system, avoids the control lag caused by the cooperation of multiple components, improves the system response speed, and is more practical.

[0035] Rotating knob 402 can quickly rotate valve ball 2 to switch between pipeline on / off or diversion modes; rotating dial 504 can adjust the flow ratio, and the lateral position of valve disc 3 is stably maintained by the engagement of protrusion 406a of brake ring 406 and groove 504a of dial 504, ensuring that the flow ratio remains constant after adjustment and avoiding adjustment failure due to vibration or other factors.

[0036] In addition, pressing down on knob 402 will release the locked state of valve disc 3 after position adjustment. Under the reset force of spring 303, valve disc 3 can quickly return to the center and restore the equal flow split state. The operation logic is clear, convenient and efficient.

[0037] This application retains the on / off switching function of the traditional three-way ball valve and adds a flow ratio adjustment function. It has a compact structure, is easy to install, does not change the connection status with other accessories, and can directly replace the existing traditional three-way valve, making it more adaptable.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

The dial (504) has grooves (504a) evenly distributed on its outer circumference. A brake ring (406) is fixed on the top side of the knob (402). Several protrusions (406a) that engage with and fit the grooves (504a) are distributed around the top side of the brake ring (406). A positioning screw sleeve (6) that supports the rotation of the valve stem (401) is installed on the top side of the valve body (1). A fixing ring is provided inside the positioning screw sleeve (6). The valve stem (401) is provided with a movable ring (401a) that abuts against the bottom side of the fixed ring. The valve stem (401) below the knob (402) is fitted with a compression spring (405). The bottom end of the compression spring (405) abuts against the top side of the fixed ring to support the knob (402) upward to keep the top side protrusion (406a) of the brake ring (406) locking the groove (504a) so as to keep the rotation angle of the control component (5) and lock the valve disc (3) in the lateral position within the core hole (201).

8. The ball of a ball valve for liquid diversion according to claim 7, characterized in that: The valve body (1) is fixed with a positioning support (103) for mounting a positioning screw sleeve (6) on the top side, and a mounting support (104) is provided on the front side of the valve body (1). The mounting support (104) has an input hole (101) for connecting the external input end (201a) of the core hole (201) through the middle longitudinally. The valve body (1) has output holes (102) connected to the corresponding output ends (201b) on both sides. An input flange (9) is detachably connected to the outside of the mounting support (104).

9. The ball of a ball valve for liquid diversion according to claim 8, characterized in that: Output flanges (7) are installed on the outside of both output holes (102). A sealing element (8) is provided on the inside of the output flange (7). The sealing element (8) is a transversely penetrating annular body. The inside of the sealing element (8) is a sealing cone surface (801) that fits the outer circumference of the valve ball (2).

10. The method for adjusting the ball of a ball valve for liquid diversion according to claim 9, characterized in that, Includes the following steps: a. Connect the liquid input end (201a) to the input flange (9) and connect the two sets of output flanges (7) to the two external diversion pipes respectively. Turn the knob (402) to drive the valve stem (401) to rotate. Use the valve stem (401) to support the valve ball (2) to rotate until the input end (201a) of the core hole (201) is aligned with the input hole (101) of the valve body (1). The "T"-shaped core hole (201) connects the input hole (101) of the valve body (1) and the two output holes (102). The fluid is output equally to the diversion pipes on both sides through the core hole (201). b. When it is necessary to adjust the fluid distribution ratio of the two-way diversion pipes, rotate the dial (504) under the support of the knob (402). The dial (504) drives the shaft (501) and the bottom swing arm (502) to rotate. Since the transmission pin (503) at the eccentric end of the swing arm (502) vertically enters the transmission frame (301) of the valve disc (3), it pushes the transmission frame (301) to move laterally along the guide groove (205) to change the lateral position of the valve disc (3). Since the valve disc (3) serves as a separation structure from the input end (201a) to the two output ends (201b), by moving the valve disc (3) laterally, the distribution ratio of the fluid entering from the input end (201a) to the two output ends (201b) can be adjusted. c. During the rotation of the toggle switch (504), the knob (402) is pushed upward by the compression spring (405) and always maintains the tightness between the protrusion (406a) and the groove (504a), that is, it can always keep the brake ring (406) locked to the angle of the toggle switch (504). The knob (402) and the valve stem (401) as a whole are kept locked to the angle by the tightness between the fixed ring and the moving ring (401a). When it is necessary to return the valve disc (3) to the center, press the knob (402) downward to release the knob. (402) The top side protrusion (406a) locks the outer groove (504a) of the dial (504) in a locked support state. At the same time, since the valve disc (3) is in an offset position, the spring (303) on the offset side is in a compressed state. When the dial (504) is released from the locked state, the spring (303) on the compressed side pushes the valve disc (3) back to the center. At the same time, the transmission frame (301) supports the transmission pin (503), as well as the swing arm (502), shaft (501), and dial (504) to quickly rotate and reset. d. When the valve needs to be closed, turn the knob (402) to use the valve stem (401) to drive the valve ball (2) to rotate to the rear position of the input end (201a) of the core hole (201). At this time, the fluid input channel into the valve ball (2) is cut off, and the valve is closed. When it is necessary to connect one of the diversion pipes separately, turn the valve ball (2) to the output end (201b) of the other side of the core hole (201) to correspond to the closed position on the rear side of the valve body (1), so that one of the diversion pipes can be connected separately.
