DETAILED DESCRIPTION
[0041] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0042] In this disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", are defined according to the actual arrangement of the conveying pipes. Figure 1 In the drawings shown, directional terms such as "inner" and "outer" are defined relative to the outlines of the corresponding components. Terms such as "first" and "second" are used to distinguish between different components and do not imply order or importance. In the following description, when referring to the drawings, unless otherwise indicated, identical reference numerals in different figures indicate identical or similar elements.
[0043] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, a delivery pipe is provided, comprising a first tube body 1, a second tube body 2, a detection portion and a condensate discharge member 5. The first tube body 1 can be used to accommodate the liquid to be transported. The second tube body 2 is sleeved on the outside of a portion of the first tube body 1, and forms a sealed partition cavity 3 with the first tube body 1. The detection portion can be provided on the second tube body 2, and is used to obtain temperature information of the delivery pipe. The condensate discharge member 5 can be provided on the second tube body 2, and is used to connect the partition cavity 3 with an external container in an openable and closable manner, and the condensate discharge member 5 is connected to the detection portion. The external container here can be directly connected to the condensate discharge member 5, or the condensate discharge member 5 can be connected to a section of pipe first and then to the external container, and this disclosure does not limit this. The liquid to be transported here can be liquid fuel, or it can be energy such as petroleum, diesel, etc., and this disclosure does not limit this.
[0044] Through the above technical solution, the second tube body 2 is spaced apart from the first tube body 1 to provide a cooling effect for the first tube body 1, reducing the impact of the external temperature on the liquid inside the first tube body 1. A detection unit and a condensate drain 5 are provided on the second tube body 2, interconnected. The detection unit obtains temperature information from the infusion tube to detect liquid leakage within the spacer cavity 3. The condensate drain 5 is automatically controlled to open and discharge the leaked liquid out of the delivery tube for collection. This allows for timely detection and treatment of delivery tube leaks, preventing the leaked liquid from affecting the outside world and reducing environmental pollution and safety accidents.
[0045] Specifically, if Figures 2 to 4 As shown, the first tube body 1 may include a first tube body 11 and a thermal insulation member 12. The first tube body 11 is used to accommodate the liquid to be transported, and the thermal insulation member 12 may be wrapped around the outside of the first tube body 11. The thermal insulation member 12 can provide thermal insulation, reducing the impact of external temperature on the first tube body 11, and preventing excessive external temperature from heating the liquid inside the first tube body 11, causing the liquid fuel to volatilize and expand, causing the first tube body 11 to crack and leak.
[0046] Furthermore, if Figures 1 to 3 As shown, the delivery pipe is mostly laid horizontally during actual use, and the condensate draining member 5 can be set below the second tube body 2, so that when the condensate draining member 5 is opened to connect the partition cavity 3 with the external container, all the liquid in the partition cavity 3 can be drained to prevent the liquid from accumulating at the bottom and affecting other components in the delivery pipe.
[0047] According to one embodiment of the present disclosure, Figure 1 and Figure 3 As shown, the delivery pipe may further include a purge member 6 arranged on the second tube body 2, and the purge member 6 is used to connect the partition cavity 3 with the external air pipe in an openable and closable manner, and is used to move the liquid in the partition cavity 3 away from the purge member 6, which can not only clean the liquid in the partition cavity 3 adhering to the outside of the first tube body 1, but also quickly accumulate the liquid in the partition cavity 3 in one direction, thereby improving the drainage efficiency of the condensate removal member 5.
[0048] Furthermore, if Figure 1 As shown, the purge member 6 and the condensate discharge member 5 can be respectively arranged at different ends in the longitudinal direction of the second tube body 2. The purge member 6 is used to purge the liquid in the partition cavity 3 to the condensate discharge member 5, so that the liquid accumulates at the condensate discharge member 5. The liquid can be emptied by opening the condensate discharge member 5 to prevent the liquid from remaining in the partition cavity 3 due to accumulation, adhesion, etc. The purge member 6 can be arranged above one end in the longitudinal direction of the second tube body 2, and the condensate discharge member 5 can be arranged below the other end in the longitudinal direction to increase the effective range of the purge member 6 blowing the liquid and reduce the liquid residue in the partition cavity 3.
[0049] According to one embodiment of the present disclosure, Figure 1 As shown, the detection part may also include a plurality of temperature detection elements 4, which are arranged at intervals on the outer surface of the second tube body 2 to obtain temperature information of the second tube body 2. The detection part may also be connected to the purge member 6. When a leak occurs in the first tube body 1, causing liquid to leak into the partition cavity 3, the temperature of the second tube body 2 may also become abnormal. After detecting such an abnormality, the temperature detection element 4 may sound an alarm and transmit a signal to the connected purge member 6 and condensate discharge member 5. At this time, the purge member 6 is turned on, blowing the liquid to converge in one direction, and by opening the condensate discharge member 5, the liquid leaked into the partition cavity 3 is discharged. The temperature detection element 4 may be a surface thermocouple, or a temperature sensor or a thermometer, which is not limited in this disclosure.
[0050] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, the second tube body 2 includes a second tube body and sealing portions 8 disposed at each end of the second tube body. The sealing portion 8, the second tube body, and the first tube body 1 form a partition cavity 3. The sealing portion 8 may include an end plate 81, a first elastic member 82, and a fixing portion. The end plate 81 may be an annular structure, with the outer ring of the annular structure fixed to the edge of the second tube body and the inner ring of the annular structure spaced apart from the first tube body 1. The first elastic member 82 can be positioned between the end plate 81 and the first tube body 1. The fixing portion may be fixed radially outward of the first tube body 1, abutting against the first elastic member 82 and spaced axially from the end plate 81. Here, the end plate 81 may be welded to the second tube body 2. The first elastic member 82 positioned between the end plate 81 and the first tube body 1 can prevent leakage of liquid from the first tube body 1 into the partition cavity 3 and prevent liquid from overflowing from the purge member 6 during purge. The fixing portion can abut against the first elastic member 82, thereby preventing the first elastic member 82 from moving out of the gap between the end plate 81 and the first tube 1. The first elastic member 82 has a certain degree of elasticity. Even if the low temperature of the liquid inside the first tube 1 causes the first tube 1 to deform slightly, the deformation capacity of the first elastic member 82 can compensate for the deformation of the first tube 1, thereby sealing the gap between the first tube 1 and the end plate 81 and preventing liquid leakage. The first elastic member 82 can be made of an elastic resin or rubber, which is not limited in this disclosure.
[0051] Furthermore, if Figures 1 to 4As shown, the fixing portion may include a clamp 83 and a retaining ring 84. The clamp 83 is arranged on the outside of the second tube body 2 in the axial direction and fixed on the radial outside of the first tube body 1. The retaining ring 84 can be pressed between the clamp 83 and the first elastic member 82. The first tube body 1 is fixed by the clamp 83, and when installing the clamp 83, the retaining ring 84 can be pressed against the first elastic member 82 first, and then the clamp 83 can be fixed. In this way, the position of the retaining ring 84 can also be fixed by fixing the clamp 83, so that the first elastic member 82 is limited in the longitudinal direction of the first tube body 1 by the pressing of the retaining ring 84, thereby preventing the first elastic member 82 from moving and affecting the sealing effect between the first tube body 1 and the second tube body 2.
[0052] Furthermore, if Figures 1 to 4 As shown, the clamp 83 may include two arc-shaped clamping plates 831 , a support ear 832 and a second elastic member 834 . The two arc-shaped clamping plates 831 can fit the shape of the first tube body 1 and be arranged at intervals. The ears 832 can be respectively formed at both ends of the two arc-shaped clamping plates 831 and extend toward the outside of the arc-shaped clamping plates 831, wherein the ears 832 of the two arc-shaped clamping plates 831 are connected by fasteners 833 to fix the clamp 83 on the first tube body 1, and the second elastic member 834 can be respectively set in the gap between the ends of the two arc-shaped clamping plates 831 to fill the gap between the two arc-shaped clamping plates 831. Since the liquid inside the first tube body 1 is a low-temperature liquid, thermal expansion and contraction may cause the installed arc-shaped clamping plates 831 to move. The second elastic member 834 has a certain elasticity. Even if the low temperature of the liquid inside the first tube body 1 causes the arc-shaped clamping plates 831 and the first tube body 1 to undergo slight deformation, the deformation ability of the second elastic member 834 can also compensate for the deformation of the arc-shaped clamping plates 831 and the first tube body 1, so that the clamp 83 can be more stably fixed on the first tube body 1. The second elastic member 834 may be made of elastic resin or rubber, which is not limited in the present disclosure.
[0053] According to one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a support portion 7 can be connected between the first tube body 1 and the second tube body 2 to separate the first tube body 1 and support the first tube body 1. This prevents the first tube body 1 from being excessively long and sticking to the inner wall of the lower end of the second tube body 2 due to gravity, thereby affecting the cold insulation effect of the delivery pipe. If the second tube body 2 is long, multiple support portions 7 can be provided in the second tube body 2 at intervals along the length of the first tube body 1 to support the first tube body 1. The present disclosure does not limit the number and spacing of the support portions 7.
[0054] Furthermore, if Figure 1 and Figure 2As shown, the support portion 7 may include a support ring 71 and a bracket 72. The support ring 71 may be sleeved on the outside of the first tube body 1. The bracket 72 may be located in the partition cavity 3 and arranged below the first tube body 1. One end of the bracket 72 is fixedly connected to the support ring 71, and the other end abuts against the second tube body 2 to support the first tube body 1. The bracket 72 may also be bonded, welded or clamped to the bottom of the inner wall of the second tube body 2, which is not limited in this disclosure. The material of the second tube body 2 and the support portion 7 may be carbon steel, and stainless steel and alloy steel are also within the scope of protection of this disclosure.
[0055] Furthermore, if Figure 2 As shown, the support portion 7 may further include a plurality of support plates 73 spaced apart within the spacer cavity 3. One end of the support plate 73 is fixed to the support ring 71, and the other end abuts against the second tube 2, thereby securing the support ring 71 in multiple directions and limiting the position of the first tube 1 within the support ring 71 to prevent movement of the first tube 1. The support plates 73 may be spaced apart circumferentially along the support ring 71. The spacing and number of the support plates 73 may be determined based on the size of the delivery tube, and this disclosure does not limit this.
[0056] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0058] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
