The inspection personnel determine the device condition based on the amount of condensed water output from the drain pipe 9. , effectively improving the convenience of discovering slight leakage in the device, thereby enhancing the applicability of the device.

The outer surface of each group of outer flexible sealing rings 12 is elastically pressed against the inner wall of the corresponding blocking semicircular cover 6, and the inner wall of each group of inner flexible sealing rings 12 is elastically pressed against the outer surface of the delivery pipe 1. Series flanges 13 are provided on the upper and lower sides of the delivery pipe 1, and the inner side surface of each group of series flanges 13 is provided with a support ring 14. The outer surface of each group of support rings 14 is slidably plugged into the inner wall of the corresponding blocking semicircular cover 6.
[0025] In the utility model, in order to reduce the probability of uncontrollable displacement of the conveying pipe 1 and the barrier assembly 5, a protective baffle 15 for limiting the movement of the conveying pipe 1 is provided on the outer side surface of each group of support rings 14, and each group of protective baffles 15 is fixed to the corresponding support ring 14 by bolts and nuts, thereby reducing the probability of uncontrollable displacement of the conveying pipe 1 and the barrier assembly 5.

[0030] When in use, firstly, multiple groups of conveying pipes 1 are welded in series. After the conveying pipes 1 are welded in series, adjacent series flanges 13 are connected and fixed by bolts and nuts. The series flanges 13 fix adjacent barrier components 5 in series through support rings 14. After the device is assembled in series, the diversion operation is performed through the conveying pipe 1. When leakage occurs during the operation of the device, the two groups of barrier semicircular covers 6 form a barrier structure with the cooperation of limit bolts and limit threads. At the same time, the sealing bracket 11 forms a sealed space in the barrier structure with the cooperation of the flexible sealing ring 12. When leakage occurs at the connection of the conveying pipe 1, the leaked steam is converted into water droplets and discharged from between the two groups of series flanges 13. The inspectors determine the leakage location based on the discharged water droplets. When a large area of damage and leakage occurs in the conveying pipe 1, the leaked steam enters the sealed space. As the steam enters the sealed space, the steam enters the sealed space. As the input pressure increases, the value on the pressure gauge 8 in the pressure measuring tube 7 increases according to the increase in the pressure in the sealed space. The inspection personnel determine the condition of the device based on the data displayed on the pressure gauge 8. When a slight leak occurs in the delivery pipe 1, the leaked steam enters the sealed space, and the steam in the sealed space condenses as the temperature decreases. The inspection personnel separate the drain plug 10 from the drain pipe 9 during the inspection of the device, and the condensed water in the sealed space is output through the drain pipe 9. The inspection personnel determine the condition of the device based on the amount of condensed water output by the drain pipe 9. When it is determined that the device has a leak, the two groups of barrier semi-circular covers 6 are separated by the limit bolts and limit nuts, and then the barrier semi-circular covers 6 are removed from the surface of the support ring 14. After the barrier semi-circular covers 6 are removed, the leakage point is determined according to the conditions of the delivery pipe 1 and the insulation sleeve 4 for maintenance, and the device is reset after the maintenance is completed.
[0031] To sum up, the steel-jacketed steel steam insulated pipe which is easy to disassemble and overhaul has a pressure gauge 8. When a large area of damage and leakage occurs in the delivery pipe 1, the leaked steam enters the sealed space formed by the blocking semicircular cover 6, the sealing bracket 11 and the flexible sealing ring 12. As the pressure of the steam entering the sealed space increases, the value on the pressure gauge 8 in the pressure measuring tube 7 increases according to the increase in the pressure in the sealed space. The inspection personnel determine the status of the device based on the data displayed on the pressure gauge 8, which effectively improves the timeliness of the abnormal discovery of the device, thereby enhancing the practicality of the device.
[0032] The steel-jacketed steel steam insulation pipe which is easy to disassemble and overhaul passes through the drain pipe 9. When a slight leak occurs in the delivery pipe 1, the leaked steam enters the sealed space formed by the blocking semicircular cover 6, the sealing bracket 11 and the flexible sealing ring 12. The steam in the sealed space condenses as the temperature drops. During the inspection of the device, the inspection personnel separate the drain plug 10 from the drain pipe 9, and the condensed water in the sealed space is output through the drain pipe 9. The inspection personnel determine the device status based on the amount of condensed water output from the drain pipe 9, which effectively improves the convenience of discovering a slight leak in the device, thereby enhancing the applicability of the device.
[0033] The steel-jacketed steel steam insulated pipe which is easy to disassemble and overhaul has a barrier component 5. When it is determined that the device has a leak, the two groups of barrier semi-circular covers 6 are separated by limiting bolts and limiting nuts, and then the barrier semi-circular covers 6 are removed from the surface of the support ring 14. After the barrier semi-circular covers 6 are removed, the leakage point is determined according to the conditions of the conveying pipe 1 and the insulation sleeve 4 for repair, which effectively improves the convenience of the device during disassembly, assembly and maintenance, thereby enhancing the practicability of the device.
