[0037] Embodiment one: refer to Figures 1-9The steam coil of the modular quick-assembly sealing device comprises a first main pipe 1 and a second main pipe 2, a plurality of branch pipes 3 connected between the first main pipe 1 and the second main pipe 2, threaded connectors 5 connected to both ends of the branch pipes 3, and a plurality of limiting blocks 6 slidably connected in the threaded connectors 5.

[0038] In the embodiment, the plurality of branch pipes 3 are first installed between the first main pipe 1 and the second main pipe 2, the two end faces of the branch pipes 3 are abutted against the first main pipe 1 and the second main pipe 2, the threaded connectors 5 at the two ends of the branch pipes 3 are inserted into the first main pipe 1 and the second main pipe 2 and connected therewith, and the limiting blocks 6 are moved after the threaded connectors 5 are inserted into the first main pipe 1 and the second main pipe 2, and the limiting blocks 6 are abutted against the inner walls of the first main pipe 1 and the second main pipe 2, so that the threaded connectors 5 and the branch pipes 3 are prevented from falling off, the branch pipes 3 are fixedly connected, and the service life is improved. In use, the rear end of the first main pipe 1 is blocked, the front end of the second main pipe 2 is blocked, steam is injected from the front end of the first main pipe 1, so that the steam can enter the plurality of branch pipes 3 to realize the drying operation of the material, and then the steam is discharged from the rear end of the second main pipe 2, so that the whole flow process is realized. In the application, the modular structure is formed between the plurality of parts, and the installation is convenient and fast, so that the modular quick-assembly effect is achieved.

[0039] It should be noted that the two end faces of the plurality of branch pipes 3 are provided in an arc shape, the arc-shaped cross section is tightly fitted with the first main pipe 1 and the second main pipe 2, the gap at the connecting position is reduced, the arc-shaped structure is easier to align and position with the main pipe during installation, the installation accuracy and efficiency are improved, the installation personnel can more conveniently fit the branch pipes 3 with the arc-shaped faces of the two main pipes, and the installation time and adjustment times are reduced.

[0040] As another extended embodiment in the embodiment, the installation ring 4 can not be used, and the connection between the branch pipe 3 and the first main pipe 1 and the second main pipe 2 is directly welded to be fixed, so that the fixation of the branch pipe 3 is also achieved, and subsequent operations are performed.

[0041] Specifically, in the present application, the mounting ring 4 can provide certain support for the branch pipe 3, so that it is placed more stably, and the insertion pipe 5 is threadedly connected in the branch pipe 3, which can facilitate installation and disassembly, and a metal winding gasket is further provided between the insertion pipe 5 and the branch pipe 3 for sealing, so as to avoid steam leakage and ensure the sealing performance, so that the steam can better pass through the branch pipe 3 to achieve the drying effect on the material; the metal winding gasket can withstand the high temperature environment during the operation of the steam coil, and can resist the heat brought by the steam during steam transmission, and can form an effective sealing barrier to reduce the risk of steam leakage.

[0042] Secondly, during the storage or maintenance of some parts of the marine hydrology and geology survey winch, due to the relatively humid environment, the heat generated by the steam coil can be used to dry the related materials, which has been greatly popularized.

[0043] As another extended embodiment in the present embodiment, welding is used at the connection between the two main pipes and the branch pipe 3 for further fixation, in the present application, the arc-shaped fitting surface between the two main pipes and the branch pipe 3 can provide more ideal operation space and angle for the welder, so that the weld forming is more uniform and the quality is higher, under the multiple fixation of the mounting ring 4, the connection stability between the main pipe and the branch pipe 3 is further enhanced, and the damage is avoided.

[0044] Embodiment two: refer to Figures 1-6 A modular quick-mount sealing device steam coil, comprising a first main pipe 1 and a second main pipe 2, further comprising a plurality of branch pipes 3 connected between the first main pipe 1 and the second main pipe 2, a plurality of insertion pipes 5 are threadedly connected at both ends of the branch pipe 3, and the two insertion pipes 5 are respectively inserted into the first main pipe 1 and the second main pipe 2; a limiting block 6 is slidably connected in the insertion pipe 5, a fixing ring 506 is fixedly arranged in the insertion pipe 5, and a taper block 507 cooperating with the fixing ring 506 is arranged in the insertion pipe 5; in the initial state, the taper block 507 abuts against the fixing ring 506; a plurality of mounting rings 4 are sleeved on the first main pipe 1 and the second main pipe 2.

[0045] The inner wall of the mounting ring 4 is fixedly connected with a connecting block 403, the end of the connecting block 403 away from the mounting ring 4 is fixedly connected with an arc-shaped plate 402, and the arc-shaped plate 402 is fitted with the outer walls of the first main pipe 1 and the second main pipe 2.

[0046] The branch pipe 3 is provided with a threaded ring 302, a threaded block is threadedly connected on the threaded ring 302, and a first flange plate 303 is fixedly connected on the threaded block.

[0047] A second flange plate 401 is fixedly arranged on the outer wall of the mounting ring 4, the first flange plate 303 and the second flange plate 401 are connected, and the two ends of the branch pipe 3 pass through the second flange plate 401 on the mounting ring 4 and are fitted with the outer walls of the first main pipe 1 and the second main pipe 2.

[0048] In this embodiment, the mounting ring 4 is directly sleeved on the outer walls of the first main pipe 1 and the second main pipe 2 during installation, and the arc-shaped plate 402 can be closely attached to the outer walls of the first main pipe 1 and the second main pipe 2, thereby enabling the mounting ring 4 to have a certain supporting effect through the connecting block 403. The plurality of branch pipes 3 are installed between the first main pipe 1 and the second main pipe 2, and then the two ends of the branch pipe 3 pass through the second flange plate 401 on the mounting ring 4, and then are attached to the outer walls of the first main pipe 1 and the second main pipe 2. At the same time, the two end insertion pipes 5 on the branch pipe 3 are inserted into the first main pipe 1 and the second main pipe 2 and are in communication with them. The threaded block is rotated and screwed with the threaded ring 302, thereby driving the threaded block and the first flange plate 303 to move. When the first flange plate 303 moves to be attached to the second flange plate 401, the two flange plates are fixed and connected by bolts, thereby further improving the fixing effect of the branch pipe 3 and avoiding the occurrence of breakage or steam leakage at the connection between the branch pipe 3 and the two main pipes during use.

[0049] Embodiment three: refer to Figures 3-9 A modular quick-mount sealing device steam coil, comprising a first main pipe 1 and a second main pipe 2, further comprising a plurality of branch pipes 3 connected between the first main pipe 1 and the second main pipe 2, threaded connection of the insertion pipe 5 is arranged at both ends of the branch pipe 3, and the two insertion pipes 5 are respectively inserted into the first main pipe 1 and the second main pipe 2; a limiting block 6 is slidably connected in the insertion pipe 5, a fixed ring 506 is fixedly arranged in the insertion pipe 5, and a taper block 507 cooperating with the fixed ring 506 is arranged in the insertion pipe 5. In the initial state, the taper block 507 abuts against the fixed ring 506; a plurality of mounting rings 4 are sleeved on the first main pipe 1 and the second main pipe 2.

[0050] Further, a plurality of circular holes 102 are arranged on the first main pipe 1 and the second main pipe 2, a plurality of insertion rods 404 corresponding to the positions of the circular holes 102 are arranged on the inner walls of the first main pipe 1 and the second main pipe 2, the insertion pipes 5 at both ends of the branch pipe 3 are inserted into the first main pipe 1 and the second main pipe 2 through the circular holes 102, and the insertion rods 404 are inserted into the insertion pipes 5.

[0051] A supporting frame 501 is fixedly connected to the inner wall of the insertion pipe 5, a sliding rod 502 is slidably connected to the supporting frame 501, one end of the taper block 507 is fixedly connected to the sliding rod 502, the other end of the sliding rod 502 is fixedly connected to a circular plate 503, and an inclined plate 504 is arranged on the outer wall of the circular plate 503.

[0052] A limiting rod 508 is arranged on the taper block 507, the limiting rod 508 is slidably arranged on the fixed ring 506, an end of the limiting rod 508 away from the taper block 507 is provided with a baffle 509, a first elastic member 510 is arranged between the baffle 509 and the outer wall of the fixed ring 506, and the first elastic member 510 is sleeved on the outer wall of the limiting rod 508.

[0053] In this embodiment, the mounting ring 4 is directly sleeved on the outer walls of the first main pipe 1 and the second main pipe 2 during installation, and the arc-shaped plate 402 can be closely attached to the outer walls of the first main pipe 1 and the second main pipe 2, thereby enabling the mounting ring 4 to have a certain supporting effect through the connecting block 403. When the branch pipe 3 is installed, the insertion pipe 5 at both ends of the branch pipe 3 is inserted into the first main pipe 1 and the second main pipe 2 through the circular hole 102. At this time, the insertion rod 404 located in the first main pipe 1 and the second main pipe 2 is in contact with the circular plate 503 and pushes the circular plate 503 to start moving, thereby enabling the circular plate 503 to drive the sliding rod 502 to move. Then, the sliding rod 502 drives the taper block 507 connected thereto to move, thereby enabling the taper block 507 and the fixed ring 506 to be not in abutment. It needs to be particularly pointed out that the flat section on the taper block 507 is in abutment with the fixed ring 506 in the initial state, and the abutment of the two can close the channel formed in the insertion pipe 5. At this time, steam and the like cannot pass through. After the sliding rod 502 drives the taper block 507 to move, there is a gap between the taper block 507 and the fixed ring 506, thereby enabling the steam to pass through, so that normal drying operation can be started.

[0054] It needs to be pointed out that the support frame 501 is arranged on the inner wall of the insertion pipe 5, and a plurality of support frames 501 can be arranged, which can support the sliding rod 502, thereby enabling the sliding rod 502 to move more stably and not to deviate, facilitating subsequent use. Secondly, one end of the taper block 507 is arranged as a tapered surface, and one end is arranged as a flat surface. In the initial state, the flat end of the taper block 507 is attached to the fixed ring 506, and a metal winding gasket is connected at the attachment position of the two. The metal winding gasket not only can resist high temperature but also can enhance the sealing performance, thereby ensuring that the steam cannot pass through during attachment and will not be damaged under the action of high-temperature steam. After the taper block 507 moves, there is a gap between the taper block 507 and the fixed ring 506, through which the steam can pass. At this time, the normal conveying of the steam can be ensured. The limiting rod 508 arranged can limit the position of the taper block 507, thereby enabling the taper block 507 to move more stably. The first elastic member 510 arranged can enable the taper block 507 to automatically reset, thereby driving the sliding rod 502 to reset. If the branch pipe 3 breaks or the like during use, the first elastic member 510 can enable the taper block 507 to automatically reset, thereby enabling the taper block 507 to abut against the fixed ring 506 again to block the channel to form a seal, thereby avoiding excessive leakage of steam. At this time, the operator can arrange to overhaul. The first elastic member 510 can be a spring or a spring sheet, and the like. It needs to be particularly pointed out that the branch pipe 3 in the application can be continuously used after being installed between the first main pipe 1 and the second main pipe 2 and will not be easily disassembled.

[0055] The inclined plate 504 and the limiting block 6 are provided with inclined surfaces matched with each other, and the support pipe 3 is further provided with a groove 505, and the outer wall of the limiting block 6 is provided with a convex plate 601 which is slidingly arranged in the groove 505, and a second elastic element 602 is arranged between the convex plate 601 and the inner wall of the groove 505.

[0056] After the inserting rod 404 in the first main pipe 1 and the second main pipe 2 pushes the circular plate 503 to start moving, not only the tapered block 507 is driven to move so that a gap through which steam can pass exists between the tapered block 507 and the fixed ring 506, thereby ensuring the normal delivery of steam, but also the inclined plate 504 connected to the circular plate 503 starts moving when the inserting rod 404 pushes the circular plate 503 to move, and since the inclined plate 504 and the limiting block 6 are provided with inclined surfaces matched with each other, the inclined plate 504 can drive the limiting block 6 to move when the inclined plate 504 moves, so that the limiting block 6 moves outward from the groove 505, and the limiting block 6 after moving can abut against the inner wall of the first main pipe 1 and the second main pipe 2, thereby preventing the inserting pipe 5 and the support pipe 3 from being separated from the first main pipe 1 and the second main pipe 2, making the connection more stable, and further fixed through the first flange plate 303 and the second flange plate 401, so that the support pipe 3 cannot be separated, and the steam leakage is avoided.

[0057] It should be noted that the second elastic element 602 is arranged to make the limiting block 6 in the initial state be in the non-protruding state, so that the inserting pipe 5 can be inserted into the first main pipe 1 and the second main pipe 2, and the groove 505 is arranged to facilitate the connection of the convex plate 601.

[0058] Embodiment four: refer to Figure 1 and Figure 3 A modular quick-mount sealing device steam coil, comprising a first main pipe 1 and a second main pipe 2, further comprising a plurality of support pipes 3 connected between the first main pipe 1 and the second main pipe 2, and an inserting pipe 5 is threadedly connected to both ends of the support pipe 3, and the two inserting pipes 5 are respectively inserted into the first main pipe 1 and the second main pipe 2; a limiting block 6 is slidingly connected in the inserting pipe 5, and a fixed ring 506 is fixedly arranged in the inserting pipe 5, and the inserting pipe 5 is provided with a tapered block 507 matched with the fixed ring 506, and in the initial state, the tapered block 507 abuts against the fixed ring 506; a plurality of mounting rings 4 are sleeved on the first main pipe 1 and the second main pipe 2, and more further, a plugging pipe 101 is threadedly connected to both ends of the first main pipe 1 and the second main pipe 2.

[0059] In use, the first main pipe 1 and the second main pipe 2 are connected with the blocking pipes 101 at both ends, and then the end caps are connected on the blocking pipes 101 at the rear end of the first main pipe 1 and the front end of the second main pipe 2, so that the end is closed to avoid steam passing through, and then the steam enters from the front end of the first main pipe 1, passes through the branch pipes 3, and flows out from the rear end of the second main pipe 2, so that the material drying effect is achieved; the blocking pipes 101 are arranged to facilitate the blocking of the ends of the first main pipe 1 and the second main pipe 2.

[0060] The branch pipes 3 are arranged in a curved shape, and each branch pipe 3 is provided with a wear-resistant anticorrosive layer 301 on the outer surface of the bottom.

[0061] In the embodiment, the wear-resistant anticorrosive layer 301 is formed on the outer surface of the branch pipe 3 by laser cladding process, the coating thickness is 1.8-2.1mm, the coating width is a radial included angle of 110-130°, and the distance from the outermost coating to the pipe edge is controlled to be 60-120mm; the wear-resistant anticorrosive layer 301 is integrally formed at the bent surface and does not produce internal or external cracks.
