Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveying pipelines, in particular to a low-temperature liquid conveying pipeline with a sealing and heat-insulating structure. Background Art
[0002] When transporting cryogenic liquid, the delivery pipeline is generally connected to the pipeline interface of the tank body. When the delivery pipeline is connected to the interface, the liquid is transported into the tank body. When the delivery pipeline is connected to the pipeline interface on the tank body, since the pipeline on the tank body has a certain weight, the pipeline on the tank body needs to be supported to facilitate the connection of the delivery pipeline with the pipeline interface on the tank body. In addition, after the transportation is completed, the valves of the storage tank body and the delivery tank body are closed. When the valves of the storage tank body and the delivery tank body are closed, since there is cryogenic liquid remaining in the delivery pipeline and a certain pressure remaining in the pipeline, when the pipeline interface and the storage interface are separated, some cryogenic liquid may spray out, and the sprayed cryogenic liquid may splash onto the workers, possibly causing injuries to the workers.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1
[0021] See also Figure 1-3As shown, the utility model is a cryogenic liquid delivery pipeline with a sealing and heat-insulating structure, comprising a pipe body 1, on which a heat-insulating mechanism 2 is arranged, on which a cylinder 4 is slidably connected via a limiting mechanism 3, on which a supporting mechanism 5 is arranged; the supporting mechanism 5 comprises a fixing frame 51 fixedly connected to the lower side of the outer surface of the cylinder 4 and a through groove 52 penetrating and opened on the outer surface of the cylinder 4, a screw 53 is threadedly connected to the fixing frame 51, one end of the screw 53 is rotatably connected to a supporting block 54, and the support block 54 is connected to the through groove 52. The outer surface of the screw rod 53 is fixedly connected with a limit block 55. When the support block 54 coincides with the through groove 52, the limit block 55 can prevent the screw rod 53 from continuing to rotate. When the delivery pipeline is connected to the pipeline interface on the tank body, the support block 54 is lifted by the screw rod 53, and the pipeline on the tank body is supported by the support block 54, thereby facilitating the connection between the delivery pipeline and the pipeline interface on the tank body. In addition, the interface can be covered by the barrel 4 to prevent the low-temperature liquid from leaking out of the interface after the interface is separated from the port, thereby improving the safety of the device.
[0022] The heat-insulating mechanism 2 comprises a heat-insulating layer 21 arranged inside the tube body 1 and sealing rings 22 respectively fixedly connected to both ends of the tube body 1 . The sealing rings 22 can improve the sealing performance of the tube body 1 .
[0023] A support ring 6 is fixedly connected to the outer surface of the tube body 1 , and two support rings 6 are symmetrically arranged along the center of the tube body 1 .
[0024] The length of the thermal insulation layer 21 is the same as that of the pipe body 1 , and the thermal insulation layer 21 fits closely to the sealing ring 22 .
[0025] The other end of the screw rod 53 is fixedly connected with a knob 7 .
[0026] Embodiment 2
[0027] Based on Example 1, see Figure 1 and Figure 2 shown.
[0028] The limiting mechanism 3 includes a slide groove 31 opened on the outer surface of the tube body 1 and a slider 32 fixedly connected to the inner side of the cylinder 4. The slider 32 is slidably connected to the slide groove 31. By setting the limiting mechanism 3, the cylinder 4 can be limited to prevent the cylinder 4 from rotating.
[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0030] The working principle of the utility model is as follows: by sliding the cylinder 4 to one side, and then, by turning the knob 7 to drive the screw 53 to rotate, the support block 54 is lifted to a certain height, and when the pipe interface on the tank body is connected to the pipe body 1, the support block 54 is used to support the pipe on the tank body, so as to facilitate the connection between the pipe interface on the tank body and the pipe body 1 during installation, and then, the support block 54 is adjusted to the through groove 52 to transport the cryogenic liquid. After the transportation is completed, the valves of the storage tank body and the transportation tank body are closed. When the valves of the storage tank body and the transportation tank body are closed, since there is cryogenic liquid remaining in the transportation pipeline and a certain pressure remaining in the pipeline, when the pipeline interface and the storage interface are separated, some cryogenic liquid may be sprayed out. At this time, the cylinder 4 can be used to shield the sprayed cryogenic liquid to prevent the liquid from splashing onto the workers.
