[0051] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figures 1 to 14 As shown, the detachable pipe connection structure of the present invention is characterized in that it includes a water inlet tee 11, a water outlet tee 12, a connecting pipe 2, a rotating shaft 41, a sealing plate 42, a diverter plate 43 and a regulating component 5, wherein the water inlet tee 11 includes two water outlet ends, the water outlet tee 12 includes two water inlet ends, the two connecting pipes 2 are respectively connected to the two water outlet ends of the water inlet tee 11, and are connected to the two water inlet ends of the water outlet tee 12; the water inlet tee 11 includes a first vertical pipe 111, and a water inlet cavity 114 for water supply and circulation is formed inside the water inlet tee 11, and the diverter plate 43 is arranged inside the water inlet cavity 114, and divides the water inlet cavity 114 into two equal volumes The two water inlet channels are connected with the two connecting pipes 2 respectively, the end of the diverter plate 43 extends to the inside of the first vertical pipe 111, and the end of the diverter plate 43 is provided with an arc-shaped sealing groove 431; the rotating shaft 41 is rotatably arranged inside the first vertical pipe 111; the sealing plate 42 is fixedly connected to the rotating shaft 41, and the sealing plate 42 is a semicircular plate, and a sealing gasket is arranged on the side wall of the sealing plate 42. When the rotating shaft 41 rotates, the sealing plate 42 rotates to block the flow cavity of half of the first vertical pipe 111, the width of the sealing plate 42 is smaller than the diameter of the rotating shaft 41, the rotating shaft 41 is located on the inner side of the sealing groove 431, and is sealed and fitted with the sealing groove 431; the regulating component 5 is used to regulate the rotation of the rotating shaft 41.

[0053] In specific implementation, the water inlet tee 11 and the water outlet tee 12 are similar to the existing tee design. When the pipeline connection structure of the present application is used for normal water supply, the sealing plate 42 and the diverter plate 43 are also in a vertical state, and the water flows into the water inlet tee 11 from the first vertical pipe 111, and flows into the inside of the two connecting pipes 2 respectively under the diversion effect of the sealing plate 42 and the diverter plate 43, and flows out after being collected at the water outlet tee 12 through the connecting pipe 2.

[0054] When it is necessary to disassemble and maintain the connecting pipe 2 on one side, the adjusting component 5 is used to adjust the rotating shaft 41 to rotate in the direction of the connecting pipe 2 on that side. At this time, the rotating shaft 41 drives the sealing plate 42 to rotate. When the rotating shaft 41 rotates ninety degrees, the sealing plate 42 is sealed with the pipe wall of the first vertical pipe 111 under the action of the sealing gasket on its surface. At this time, the sealing plate 42 can block the water flow and cooperate with the diverter plate 43 to guide the water flow to the side of the connecting pipe 2 that has not been disassembled. At this time, the connecting pipe 2 to be maintained can be disassembled, and during the disassembly and maintenance, the shielding effect of the sealing plate 42 can prevent the water from flowing out of the disassembled connecting pipe 2, thereby preventing waste of resources.

[0055] During the disassembly and maintenance of the connecting pipe 2 on one side, water flows through the connecting pipe 2 that has not been disassembled, which can ensure the water flow requirements of the water tank. At the same time, when the connecting pipe 2 is disassembled for maintenance, there is no need to immediately connect a new connecting pipe 2, which simplifies the complexity of the disassembly and maintenance steps of the connecting pipe 2, facilitates the disassembly and maintenance of the connecting pipe 2, and is easy to use.

[0056] It should be noted that the present application also allows the outlet tee pipe 12 to be detached, and the inlet tee pipe 11 can be used as a new tee pipe in conjunction with the two connecting pipes 2, thereby improving the applicability of use.

[0057] As a preferred embodiment, the regulating component 5 includes a regulating gear 51 and two regulating racks 52, wherein the end of the rotating shaft 41 passes through and extends to the outside of the first vertical tube 111, and the regulating gear 51 is fixedly connected to the end of the rotating shaft 41; the two regulating racks 52 are respectively located on opposite sides of the regulating gear 51 and meshed with the regulating gear 51.

[0058] It also includes a counterweight sliding ring 61, and the regulating component 5 also includes a connecting rod 53 and a sliding rod 54, wherein the connecting rod 53 is fixedly connected to the regulating rack 52, and the sliding rod 54 is slidingly connected to the connecting rod 53; the counterweight sliding ring 61 is slidingly arranged relative to the water inlet tee pipe 11, and has the same sliding path as the sliding rod 54, and the counterweight sliding ring 61 is fixedly connected to the sliding rod 54.

[0059] The water inlet tee pipe 11 also includes two diverter pipes 112 and two second vertical pipes 113, wherein the two diverter pipes 112 are both connected to the water outlet end of the first vertical pipe 111, and the diverter plate 43 is arranged at the connection between the two diverter pipes 112 and the first vertical pipe 111; the two second vertical pipes 113 are respectively connected to the two diverter pipes 112, and the counterweight sliding ring 61 is slidably sleeved on the second vertical pipes 113, the second vertical pipes 113 and the first vertical pipe 111 have the same extension direction, and the water outlet tee pipe 12 has the same shape as the water inlet tee pipe 11

[0060] When water flows through the connecting pipes 2 on both sides, the regulating gear 51 is located in the middle of the two regulating racks 52 , and the sliding rod 54 is slidably connected to the deepest position of the connecting rod 53 . At this time, the sliding rod 54 conflicts with the counterweight sliding ring 61 .

[0061] When it is necessary to maintain the connecting pipeline 2 on that side, the counterweight sliding ring 61 on that side is adjusted to slide downward. At this time, the counterweight sliding ring 61 first drives the sliding rod 54 to slide along the connecting rod 53. After the sliding rod 54 slides downward to the maximum distance, the sliding rod 54 drives the connecting rod 53 to move downward together. The connecting rod 53 drives the adjusting rack 52 on this side to move downward and drives the adjusting gear 51 to rotate, thereby completing the rotation adjustment processing of the rotating shaft 41. At this time, the adjusting rack 52 on the other side moves upward under the action of the adjusting gear 51, and the adjusting rack 52 drives the connecting rod 53 to move upward along the sliding rod 54, so that the counterweight sliding ring 61 on this side can realize the rotation adjustment processing of the rotating shaft 41 without sliding. No matter which side of the connecting pipeline 2 needs to be disassembled and maintained, it is only necessary to adjust the configuration sliding ring 61 on that side to slide downward, which is convenient to use.

[0062] It should be noted that the diverter pipe 112 is an arc-shaped curved pipe to reduce the energy consumption generated when the water flows through the diverter pipe 112 .

[0063] As a preferred embodiment, the two water outlet ends of the water inlet tee pipe 11 are respectively provided with two first assembly flanges 311, the two water inlet ends of the water outlet tee pipe 12 are respectively provided with second assembly flanges 312, and the two ends of the connecting pipe 2 are respectively provided with first connecting flanges 321 and second connecting flanges 322, the first connecting flange 321 and the first assembly flange 311 are detachably connected, and the second connecting flange 322 and the second assembly flange 312 are detachably connected.

[0064] It also includes a push rod 62 , wherein a limiting hole 3111 is opened on the first assembly flange 311 ; the push rod 62 is arranged on the first connection flange 321 , and passes through the limiting hole 3111 to abut against the counterweight sliding ring 61 .

[0065] In the specific implementation, the connection between the connecting pipe 2 and the water inlet tee 11 and the water outlet tee 12 is completed by connecting the connecting flange with the assembly flange. When the first connecting flange 321 is regulated to be connected with the first assembly flange 311, the push rod 62 passes through the limiting hole 3111 and slides along the limiting hole 3111. At this time, the push rod 62 is used to increase the stability of the connection of the first connecting flange 321 under the limitation of the push rod 62. The push rod 62 contacts the counterweight sliding ring 61 and pushes the counterweight sliding ring 61 to move upward. After the first connecting flange 321 is connected with the first assembly flange 311, the counterweight sliding ring 61 slides to the top. At this time, the sliding rod 54 slides to the inside of the connecting rod 53, and the connecting rod 53 contacts the counterweight sliding ring 61. Under the restriction of the two connecting rods 53, the regulating gear 51 is located in the middle position of the regulating rack 52, and a certain regulating rack 52 cannot overcome the restriction of the connecting rod 53 and move upward alone. In this way, the push rod 62 plays a role in supporting and positioning the counterweight sliding ring 61.

[0066] In this way, when one side of the connecting pipeline 2 needs to be disassembled for maintenance, the first connecting flange 321 connected to the first assembly flange 311 needs to be disassembled first. At this time, the push rod 62 moves along the limit hole 3111 and gradually disengages from the first assembly flange 311. As the push rod 62 moves, the counterweight slide ring 61 also gradually slides downward under its own gravity. In this way, after the connecting pipeline 2 is completely disassembled, the counterweight slide ring 61 also naturally slides down to conflict with the first assembly flange 311. At this time, the control rack 52 corresponding to the counterweight slide ring 61 on this side moves downward accordingly, and the adjustment of the sealing plate 42 is completed by driving the control gear 51 to rotate. The rotation adjustment of the sealing plate 42 is convenient. After the connecting pipeline 2 that needs maintenance is disassembled, the sealing plate 42 automatically turns to the side of the disassembled connecting pipeline 2 and blocks it. No additional force is required to rotate and adjust the rotating shaft 41, which is convenient to use.

[0067] As a preferred embodiment, when the first connecting flange 321 is connected to the first assembly flange 311, the distance between the counterweight sliding ring 61 and the first assembly flange 311 is a, the maximum distance that the sliding rod 54 slides outward relative to the connecting rod 53 is b, the length of the regulating rack 52 is c, and the relationship between a, b, and c is: b<a<2b<c.

[0068] With such a design, when disassembling the connecting pipe 2, the counterweight sliding ring 61 on the corresponding side first drives the sliding rod 54 to move along the connecting rod 53 by a distance b. At this time, the sliding rod 54 slides to the maximum distance. Since a>b, the counterweight sliding ring 61 can carry the sliding rod 54 and the connecting rod 53 to drive the corresponding regulating rack 52 to move downward. At this time, the connecting rod 53 on the other side slides upward along the sliding rod 54. Since a<2b, the counterweight sliding ring 61 can slide smoothly to the bottom. At this time, the regulating gear 51 drives the rotating shaft 41 to rotate ninety degrees toward the disassembly side, and the sealing plate 42 completes the blocking of the water inlet channel on the disassembly side. Since the regulating gear 51 is located in the middle of the regulating rack 52 during normal water supply, by setting c>2b, when the counterweight sliding ring 61 slides and is aligned with the first assembly flange 311, the counterweight sliding ring 61 can drive the regulating rack 52 to move and drive the regulating gear 51 to rotate.

[0069] As a preferred embodiment, the connecting pipeline 2 includes a fixed pipe 21 and a sliding pipe 22 which are slidably connected to each other, wherein the first connecting flange 321 is arranged at the end of the sliding pipe 22, and the second connecting flange 322 is arranged at the end of the fixed pipe 21.

[0070] With this design, when the connecting pipe 2 is disassembled and maintained, the sliding pipe 22 is adjusted to slide along the fixed pipe 21, so that the top cover 62 can smoothly slide along the limiting hole 3111 and detach from the first assembly flange 311, thereby facilitating the disassembly of the connecting pipe 2.

[0071] As a preferred embodiment, it also includes a clamping component 7, wherein the clamping component 7 is arranged on the counterweight sliding ring 61, and when the counterweight sliding ring 61 slides to conflict with the first assembly flange 311, the clamping component 7 is used to locate the sliding position of the counterweight sliding ring 61.

[0072] The clamping component 7 includes a positioning block 71 and a spring 72, wherein a mounting groove 611 is provided on the inner side of the counterweight slide ring 61, the positioning block 71 is slidably arranged inside the mounting groove 611, and a positioning groove 1131 for the positioning block 71 to be inserted is provided on the outer side of the second vertical pipe 113, and the positioning block 71 is an arc-shaped block; the spring 72 is in conflict with the positioning block 71 and the mounting groove 611, and is used to reset the sliding position of the positioning block 71.

[0073] In a specific implementation, when the counterweight slide ring 61 slides under its own gravity until it conflicts with the first assembly flange 311, the side wall of the second vertical pipe 113 can squeeze the positioning block 71 and cause the spring 72 to contract. When the counterweight slide ring 61 slides under its own gravity until it conflicts with the first assembly flange 311, the positioning block 71 is relative to the positioning slot 1131. The spring 72 is reset and pushes the positioning block 71 to be inserted into the positioning slot 1131. Since the positioning block 71 is an arc-shaped block, a simple positioning process of the counterweight slide ring 61 can be completed under the restriction of the positioning block 71 to prevent the counterweight slide ring 61 from accidentally sliding upward, thereby increasing the stability of the sealing plate 42 in blocking the water flow when the connecting pipeline 2 is disassembled.

[0074] The working principle of the present invention is introduced below:

[0075] When water is supplied and transported in the present application, the sealing plate 42 and the diverter plate 43 are also in a vertical state, and the water flows into the water inlet tee 11 from the first vertical pipe 111, and under the diverting action of the sealing plate 42 and the diverter plate 43, the water flows through the two diverter pipes 112 and the second vertical pipe 113 respectively into the interior of the two connecting pipes 2, and then flows out after being collected at the water outlet tee 12 through the connecting pipe 2. When it is necessary to disassemble and maintain the connecting pipe 2 on one side, the connecting pipe 2 on that side is directly disassembled. During disassembly, the connecting rod 53 needs to be adjusted to move downward to be separated from the first assembly flange 311. As the top rod 62 moves, the counterweight sliding ring 61 gradually slides downward under the action of its own gravity. In this way, after the connecting pipe 2 is completely disassembled, the counterweight sliding ring 61 also naturally slides down to conflict with the first assembly flange 311. When disassembling the connecting pipe 2, the counterweight sliding ring 61 on the corresponding side first drives the sliding rod 54 to move a distance b along the connecting rod 53. At this time, the sliding rod 54 slides to the maximum distance. Since a>b, At this time, the counterweight sliding ring 61 can carry the sliding rod 54 and the connecting rod 53 to drive the corresponding regulating rack 52 to move downward. At this time, the connecting rod 53 on the other side slides upward along the sliding rod 54. Since a<2b, the counterweight sliding ring 61 can smoothly slide to the bottom. At this time, the regulating gear 51 drives the rotating shaft 41 to rotate ninety degrees toward the disassembly side. The sealing plate 42 is sealed with the pipe wall of the first vertical pipe 111 under the action of the sealing gasket on its surface. At this time, the sealing plate 42 can block the water flow and cooperate with the diverter plate 43 to guide the water flow to the side of the connecting pipe 2 that has not been disassembled. At this time, the connecting pipe 2 to be maintained can be disassembled.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
