[0031] Reference Figures 1 to 7 According to a preferred embodiment of the present application, the valve mechanism will be described in detail below, which includes a switch valve 10 and two joint members 20. The switch valve 10 includes a valve body 11 having a mounting cavity 1101 and two interfaces 1102, both of which communicate with the mounting cavity 1101, and two joint members 20 are sealingly connected to the valve body 11 in a manner corresponding to two interfaces 1102 respectively, and the joint member 20 is connected to the connecting pipeline by plug-in connection.

[0032] The switch valve 10 further includes a flow control assembly 12, which is installed in the mounting cavity 1101, and the flow control assembly 12 is arranged to be able to communicate or block the two interfaces 1102.

[0033] It is worth mentioning that the types of the joint member 20 are divided into joint member one 20A, joint member two 20B and joint member three 20C.

[0034] In one embodiment, both of the joint members 20 are the joint member one 20A, wherein the joint member one 20A is implemented as any one of male and female joints to be connected to the connecting pipeline formed with male joint or female joint by plug-in connection of male and female joints, so as to realize quick connection.

[0035] As a preferred embodiment of the above embodiment, either of the two said joint members 20A is implemented as any one of a VDA male joint and a VDA female joint, or any one of a SAE male joint and a SAE female joint, or any one of a CQC male joint and a CQC female joint.

[0036] In another embodiment, both of the two said joint members 20 are the second joint member 20B, wherein the second joint member 20B is implemented as a bellows joint to be inserted into a mating pipe implemented as a flexible material.

[0037] In yet another embodiment, one of the two said joint members 20 is the first joint member 20A, and the other of the two said joint members 20 is the second joint member 20B.

[0038] Reference Figures 2 to 3 And Figures 8 to 10 It is worth mentioning that at least one of the two said joint members 20 is the third joint member 20C, which comprises an outer discharge pipe 21C, an outer discharge control assembly 22C, a flexible member 23C, and a main pipe 24C, wherein the main pipe 24C has a main flow channel 2401C, each of the main pipes 24C is installed on the valve body 11, and each of the main flow channels 2401C is in communication with one of the interfaces 1102, and the end of the main pipe 24C away from the valve body 11 is inserted into a mating pipe. The outer discharge pipe 21C comprises a pipe body 211C, which has an outer discharge flow channel 21101C, and the pipe body 211C is installed on the main pipe 24C in the radial direction, and the outer discharge flow channel 21101C is in communication with the corresponding main flow channel 2401C. The outer discharge control assembly 22C comprises an outer discharge control member 221C, which is movably installed on the outer discharge flow channel 21101C away from or close to the corresponding main flow channel 2401C, and the two ends of the flexible member 23C are connected to the outer discharge control member 221C and the pipe body 211C, respectively. The third joint member 20C has a drainage structure 201C in communication with the outer discharge flow channel 21101C.

[0039] The outer discharge pipe 21C further comprises an internal assembly 212C arranged on the inner wall of the pipe body 211C. The outer discharge control member 221C is located on the side of the internal assembly 212C close to the main flow channel 2401C, and the internal assembly 212C is located in the moving direction of the outer discharge control member 221C when the outer discharge control member 221C moves away from the main flow channel 2401C in the outer discharge flow channel 21101C, and the end of the outer discharge control member 221C away from the main flow channel 2401C forms a drainage gap 202C with the inner wall of the pipe body 211C, which is in communication with the drainage structure 201C and the outer discharge flow channel 21101C.

[0040] The outer discharge control member 221C is arranged to abut against the built-in component 212C under the action force applied by the elastic member 23C to close the outer discharge flow passage 21101C by sealing connection of the built-in component 212C and the pipe body 211C, so that the fluid flowing into the outer discharge flow passage 21101C from the main flow passage 2401C near one end of the main flow passage 2401C is intercepted after flowing through the drainage structure 201C and the drainage gap 202C and cannot be guided to the end of the outer discharge flow passage 21101C away from the main flow passage 2401C. The outer discharge control member 221C can move in the outer discharge flow passage 21101C close to the main flow passage 2401C under an external force opposite to the action force applied by the elastic member 23C to separate from the built-in component 212C, so that the fluid flowing into the outer discharge flow passage 21101C from the main flow passage 2401C near one end of the main flow passage 2401C is guided to the end of the outer discharge flow passage 21101C away from the main flow passage 2401C after flowing through the drainage structure 201C and the drainage gap 202C.

[0041] In this way, the fluid flowing into the docking pipe can be discharged through the joint member three 20C to meet the actual use requirements. For example, when the switch valve 10, the joint member 20 and the fluid input device are arranged in sequence along the fluid flow direction, the fluid in the docking pipe between the switch valve 10 and the fluid input device can be discharged through the joint member 20, facilitating the maintenance work. In addition, before discharging the fluid, the external pipe is inserted into the pipe body 211C and the outer discharge control member 221C is pressed, at which time the fluid in the main flow passage 2401C flows into the external pipe through the outer discharge flow passage 21101C. The whole operation is simple and convenient, and rapid drainage is achieved.

[0042] Preferably, one end of the main pipe 24C away from the valve body 11 is implemented as a bamboo joint pipe to be inserted into the docking pipe implemented as an elastic material.

[0043] Preferably, the elastic member 23C is implemented as a spring.

[0044] Preferably, when the outer discharge control member 221C is separated from the built-in component 212C, the elastic member 23C is arranged to be compressed at one end of the outer discharge control member 221C close to the main flow passage 2401C. When the outer discharge control member 221C is only subjected to the elastic force of the elastic member 23C, the outer discharge control member 221C is pushed by the elastic member 23C to move away from the main flow passage 2401C in the outer discharge flow passage 21101C.

[0045] As deformable, when the outer control member 221C is separated from the inner assembly 212C, the elastic member 23C is arranged at the end of the outer control member 221C away from the main flow channel 2401C in a stretched manner. When the outer control member 221C is only subjected to the elastic force of the elastic member 23C, the outer control member 221C is pulled by the elastic member 23C to move in the outer flow channel 21101C away from the main flow channel 2401C.

[0046] Preferably, the inner assembly 212C comprises at least one sealing member 2121C arranged on the inner circumferential wall of the pipe body 211C. The outer control member 221C comprises a blocking portion 2211C which forms the drainage gap 202C with the inner wall of the pipe body 211C. The sealing member 2121C is located in the moving direction of the blocking portion 2211C when the outer control member 221C moves in the outer flow channel 21101C away from the main flow channel 2401C. The blocking portion 2211C closes the outer flow channel 21101C by abutting against the sealing member 2121C.

[0047] Preferably, the sealing member 2121C and at least part of the blocking portion 2211C are implemented in rubber material.

[0048] As preferably, the sealing member 2121C is implemented as a rubber ring. After the outer control member 221C moves in the outer flow channel 21101C to be away from the main flow channel 2401C, the blocking portion 2211C extrudes the sealing member 2121C to deform, and the outer flow channel 21101C is closed by the abutting action of the blocking portion 2211C and the sealing member 2121C.

[0049] Further, the built-in component 212C further comprises a limiting member 2122C located at a side of the sealing member 2121C close to the main flow channel 2401C. The external discharge control member 221C further comprises a blocked portion 2212C connected with the blocking portion 2211C and located at a side of the blocking portion 2211C close to the main flow channel 2401C, and the limiting member 2122C is oppositely arranged with the blocked portion 2212C and located in a moving direction of the blocked portion 2212C when the external discharge control member 221C moves away from the main flow channel 2401C in the external discharge flow channel 21101C. After the external discharge control member 221C moves in the external discharge flow channel 21101C to move away from the main flow channel 2401C, the blocked portion 2212C and the limiting member 2122C abut to be intercepted to limit the moving stroke of the external discharge control member 221C by the limiting member 2122C, so as to ensure that the blocking portion 2211C can effectively abut against the sealing member 2121C.

[0050] In an embodiment, the sealing member 2121C is oppositely arranged with the blocking portion 2211C. After the external discharge control member 221C moves in the external discharge flow channel 21101C to move away from the main flow channel 2401C, the blocking portion 2211C abuts against the sealing member 2121C to be limited to move and cooperates with the sealing member 2121C to close the external discharge flow channel 21101C, and at this time, the limiting member 2122C and the blocked portion 2212C are not arranged.

[0051] Preferably, the drain structure 201C is formed on the outer control member 221C. The drain structure 201C comprises at least one lateral hole 2011C and a drain groove 2012C, wherein the drain groove 2012C is formed by the blocking portion 2211C and the blocked portion 2212C, and the drain groove 2012C faces the main flow channel 2401C, the lateral hole 2011C is formed on the blocking portion 2211C close to the end of the blocked portion 2212C, and the two ends of the lateral hole 2011C communicate with the drain groove 2012C and the drain gap 202C respectively. After the outer control member 221C moves in the outer discharge flow channel 21101C to move away from the main flow channel 2401C, the end of the blocking portion 2211C away from the blocked portion 2212C abuts against the sealing member 2121C to close the outer discharge flow channel 21101C. When the outer control member 221C is separated from the built-in assembly 212C, the fluid flowing from the main flow channel 2401C to the end of the outer discharge flow channel 21101C close to the main flow channel 2401C is guided into the lateral hole 2011C through the drain groove 2012C, and then flows through the drain gap 202C to the end of the outer discharge flow channel 21101C away from the main flow channel 2401C. In other words, the fluid introduced into the outer discharge flow channel 21101C flows through the inside of the outer control member 221C.

[0052] In an embodiment, the drain structure 201C is implemented as a gap between the blocked portion 2212C and the inner wall of the pipe body 211C. When the outer control member 221C is separated from the built-in assembly 212C, the fluid flowing from the main flow channel 2401C to the end of the outer discharge flow channel 21101C close to the main flow channel 2401C flows through the gap and the drain gap 202C in sequence to the end of the outer discharge flow channel 21101C away from the main flow channel 2401C. In other words, the fluid introduced into the outer discharge flow channel 21101C flows on the outer circumferential side of the outer control member 221C.

[0053] The outer discharge control assembly 22C further comprises a plug member 222C which is detachably inserted into the end of the outer discharge flow channel 21101C away from the main flow channel 2401C to block the outer discharge flow channel 21101C, so as to prevent external contaminants from entering the outer discharge flow channel 21101C from the end of the outer discharge flow channel 21101C away from the main flow channel 2401C to contaminate the subsequent discharge fluid, or even affect the fluid discharge.

[0054] The outer discharge pipe 21C further comprises a locking ring 213C mounted on the pipe body 211C, and the plug 222C is inserted into the outer discharge passage 21101C away from the main passage 2401C and is locked or unlocked by the locking ring 213C, so as to ensure that the plug 222C can tightly block the end of the outer discharge passage 21101C away from the main passage 2401C, and facilitate the discharge of the exhaust.

[0055] Preferably, the side wall of the end of the pipe body 211C away from the main passage 24C forms at least one through hole 21102C communicating with the outer discharge passage 21101C. The locking ring 213C is mounted in the outer discharge passage 21101C and partially extends from the through hole 21102C to form a pressing portion 2131C, and the locking ring 213C further forms at least one locking portion 2132 adjacent to the pressing portion 2131C and located in the outer discharge passage 21101C. The locking ring 213C elastically deforms in such a way that the locking portion 2132 is close to the inner wall of the pipe body 211C by the action force applied to the pressing portion 2131C in the direction of the through hole 21102C extending into the outer discharge passage 21101C. The periphery of the plug 222C forms at least one hook block 2221C, and the locking ring 213C locks and connects the plug 222C and the pipe body 211C in such a way that the locking portion 2132 is located in the direction of the plug 222C being pulled out of the outer discharge passage 21101C and abuts against the hook block 2221C.

[0056] Preferably, the hook block 2221C is provided with two, and the two hook blocks 2221C are oppositely arranged. The through hole 21102C is provided with two, and the two through holes 21102C are oppositely arranged. The pressing portion 2131C and the locking portion 2132 are also provided with two, and each pressing portion 2131C is adjacent to two locking portions 2132. The locking ring 213C is assembled on the pipe body 211C in such a way that the two locking portions 2132 are oppositely located in the outer discharge passage 21101C, and the two pressing portions 2131C extend out of the outer discharge passage 21101C through the two through holes 21102C, respectively. When the two pressing portions 2131C are subjected to the action force in the direction of the through hole 21102C extending into the outer discharge passage 21101C, the two locking portions 2132 of the locking ring 213C are away from each other to be staggered with the two hook blocks 2221C of the plug 222C inserted into the outer discharge passage 21101C, so as to avoid enough space to allow the plug 222C to be pulled out of the outer discharge passage 21101C.

[0057] It is worth mentioning that the plug 222C is inserted into the pipe body 211C in a manner that abuts against and applies a force to the outer discharge control member 221C opposite to the force applied by the elastic member 23C, so that the outer discharge control member 221C is kept separated from the built-in assembly 212C, the sealing member 2121C of the built-in assembly 212C is located between the pipe body 211C and the plug 222C inserted into the pipe body 211C, and the plug 222C is sealedly connected with the pipe body 211C by the sealing member 2121C of the built-in assembly 212C to block the outer discharge passage 21101C, at this time, the plug 222C not only prevents external dirt from entering the outer discharge passage 21101C, but also hinders the fluid in the outer discharge passage 21101C from being discharged.

[0058] The outer discharge control member 221C further comprises an abutting portion 2213C formed on the end face of the blocking portion 2211C away from the blocked portion 2212C. When the plug 222C is inserted into the pipe body 211C, the plug 222C abuts against the abutting portion 2213C in a manner that the end face of the plug 222C facing the outer discharge control member 221C corresponds to the blocking portion 2211C with a spacing therebetween, so that the fluid flowing through the drainage gap 202C to the end portion of the outer discharge passage 21101C away from the main passage 2401C can flow to the end face of the blocking portion 2211C, and when the plug 222C is replaced by the external pipe with the hook block 2221C, the fluid can be introduced into the external pipe to achieve external discharge.

[0059] Specifically, when the fluid is discharged externally, the plug 222C is removed, the outer discharge control member 221C abuts against the built-in assembly 212C under the action of the elastic member 23C to automatically close the outer discharge passage 21101C, the external pipe with the hook block 2221C is inserted into the pipe body 211C, abuts against the abutting portion 2213C, and is locked to the pipe body 211C by the cooperation of the hook block 2221C and the locking ring 213C, at this time, the external pipe abuts against the sealing member 2121C, and the fluid flowing through the drainage gap 202C to the end portion of the outer discharge passage 21101C away from the main passage 2401C enters the external pipe for external discharge.

[0060] In an embodiment, both the joint members 20 are the joint member three 20C, so that after the two interfaces 1102 of the flow control assembly 12 are blocked, the fluid flowing to the valve body 11 and discharged by the valve body 11 can be discharged externally.

[0061] In another embodiment, one of the joint members 20 is implemented as the joint piece three 20C, and the other joint member 20 is the joint piece one 20A.

[0062] In another embodiment, one of the joint members 20 is implemented as the joint piece three 20C, and the other joint member 20 is the joint piece two 20B.

[0063] In this way, the type of the joint member 20 assembled to the on-off valve 10 is not limited, increasing the flexibility of use and meeting more use requirements.

[0064] In an embodiment, the joint member 20 is detachably and sealingly connected to the valve body 11 for replacement.

[0065] As a preferred embodiment of the above embodiment, the connection mode of the joint member 20 to the valve body 11 includes but is not limited to welding, bonding, and threaded connection.

[0066] In another embodiment, the joint member 20 is welded to the valve body 11 as a whole.

[0067] Reference Figures 4 to 7 Preferably, the flow control assembly 12 includes a flow control body 121 and at least one blocking piece 122, the flow control body 121 is rotatably mounted in the mounting cavity 1101, the blocking piece 122 is formed on the outer wall of the flow control body 121 and located between the flow control body 121 and the inner wall of the mounting cavity 1101, and the size of the blocking piece 122 is greater than the size of the interface 1102. The flow control body 121 has a passage 12101, the port of the passage 12101 is adjacent to the blocking piece 122, and the flow control body 121 is arranged to be rotatable to communicate or misalign the passage 12101 with any two interfaces 1102.

[0068] When the flow control body 121 is rotated to communicate the passage 12101 with any two interfaces 1102, the fluid flowing through one of the interfaces 1102 flows through the passage 12101 and is discharged by the other interface 1102. When the flow control body 121 is rotated to misalign the passage 12101 with any two interfaces 1102, any two interfaces 1102 correspond to the blocking piece 122, and the blocking piece 122 blocks any two interfaces 1102 from the mounting cavity 1101 by sealingly connecting the flow control body 121 to the valve body 11, at this time the flow control assembly 12 blocks the fluid flow.

[0069] In this way, the switch valve 10 can effectively control the flow of fluid, effectively avoid the fluid leakage due to insufficient sealing, and ensure that the switch valve 10 can be normally used.

[0070] Preferably, the blocking member 122 is made of rubber.

[0071] Preferably, the blocking member 122 is provided with two, and the included angle formed by the two blocking members 122 extending to the rotation center of the flow control body 121 is consistent with the included angle formed by the two interfaces 1102 extending to the mounting cavity 1101. In this way, when the flow control assembly 12 rotates to make the channel 12101 consistent with the two interfaces 1102, the two blocking members 122 are respectively consistent with the two interfaces 1102, and the two blocking members 122 block the fluid by cutting off the two interfaces 1102.

[0072] The flow control body 121 has a flow control member 1211, the channel 12101 is formed in the flow control member 1211, and the blocking member 122 is formed on the outer wall of the flow control member 1211. The flow control member 1211 is rotatably arranged in the mounting cavity 1101.

[0073] The valve body 11 also has a mounting port 1103, which is in communication with the mounting cavity 1101, and the size of the mounting port 1103 is adapted to the flow control member 1211. The flow control body 121 also has a head 1212, which is formed by the flow control member 1211 extending. When the flow control member 1211 is assembled in the valve body 11, part of the flow control member 1211 extends out of the mounting port 1103 and is sealingly connected with the valve body 11, and the end of the flow control member 1211 extending out of the mounting port 1103 is connected with the head 1212, so as to manually control the switch valve 10 by the worker.
