Description
技术领域technical field
本实用新型涉及一种管排充氮密封装置，具体涉及一种管排充氮密封工装。The utility model relates to a pipe exhaust and nitrogen sealing device, in particular to a pipe exhaust and nitrogen sealing tool.
背景技术Background technique
在石化、电力等工业很多产品均涉及多排管长途运输时需充装惰性气体(如氮气)进行保护，保证充装气体不外泄，保持管内气体压力不变，将直接影响到产品的最终质量，关系到产品能否正常运行。传统的的充装气体方法是用与管外径相等的塑料盖进行密封，气体易外泄，需不断观察，发现泄漏需补充气体。且长途运输塑料盖易因震动掉落使气体排空，同时管内气体压力无法测量，使管排各管受力不均，很难达到保护产品的作用。Many products in petrochemical, electric power and other industries involve multi-row pipes for long-distance transportation, which need to be filled with inert gas (such as nitrogen) for protection to ensure that the filled gas does not leak out and keep the gas pressure in the pipes constant, which will directly affect the final product. Quality is related to whether the product can function normally. The traditional method of filling gas is to seal it with a plastic cover equal to the outer diameter of the tube. The gas is easy to leak out, so it needs to be constantly observed, and the gas needs to be replenished if the leak is found. In addition, the long-distance transportation of the plastic cover is easy to cause the gas to be emptied due to vibration and drop. At the same time, the gas pressure in the tube cannot be measured, so that the stress on each tube of the tube row is uneven, and it is difficult to achieve the effect of protecting the product.

具体实施方式Detailed ways
下面结合上说明书附图对本发明作进一步说明：The present invention will be further described below in conjunction with the accompanying drawings of the description:
如图1所示，一种管排充氮密封工装，包括密封盖1、拉杆2、表接头3和管4，密封盖1与盖在管4的开口上，拉杆2的一端与管4连接，拉杆2的另一端与密封盖1通过螺栓连接，表接头3与管4连接。As shown in Figure 1, a pipe exhaust nitrogen sealing tool, including a
密封盖按管排封口管径加工，表接头连接压力表显示管内气体压力，密封盖由拉杆固定、把紧，保证管4内气体压力保持不变。该胎具按管排的管子数量、管外径加工密封盖，使之满足产品设计要求。管排充装氮气时，通过拉杆对密封盖进行固定、拉紧，保证充装气体不外泄，保持管内气体压力不变，不必重复充装氮气，降低了成本，提高了工作效率，保证充氮保护的质量，确保安全生产。The sealing cover is processed according to the pipe diameter of the sealing port of the tube row, and the gauge joint is connected with a pressure gauge to display the gas pressure in the tube. The sealing cover is fixed and tightened by a pull rod to ensure that the gas pressure in the tube 4 remains constant. According to the number of tubes in the tube row and the outer diameter of the tubes, the sealing cover is processed to meet the product design requirements. When the tube row is filled with nitrogen, the sealing cover is fixed and tightened by the tie rod to ensure that the filling gas does not leak out, and the gas pressure in the tube remains constant. It is not necessary to repeatedly fill nitrogen, which reduces costs and improves work efficiency. The quality of nitrogen protection ensures safe production.
