 众所周知,生料带是用来密封管道连接处,使管道的密封性更好,如果密封不好 会出现泄漏现象。 就目前而言,泄漏是自然界常见的现象。日常个活中如自来水、煤气的泄漏常常 给人们带来不便甚至危害;工业中如压力容器、管道、反应器、阀门、液压没备 、运输工具一旦发生泄漏,轻则造成能源和原材料的大量浪费、设备不能正常工 作,重则导致设备报废、整个工厂或系统陷于瘫痪、人员伤亡和严重的环境污染 。因此,人们在生产实践中千方百计地设法防止和消除泄漏。 密封是指机器、设备的连接处没有泄漏的现象。能起密封作用的零部件称密封件 。较复杂的密封连接称为密封系统或密封装置。常用的密封设备有生料带、密封 胶、胶黏剂等。 在工程实践中,常用密封性或紧密性这个概念来评价密封连接的有效性。系统和 设备的紧密性可以通过泄漏率的大小来许定。从物理意义上讲,并不存在绝对的 紧密件。所谓紧密性应该像其他物理量—样。可以定量地加以衡量。文献将连接 的紧密性定义为:“在一定的操作条件下,连接的泄漏率低于某一规定的指标泄 漏率;或在规定的泄漏率指标下,连接能够承受特定的操作条件。满足上述条件 的连接是紧密的,反之则认为是不紧密的”。实际上连接的泄漏率大小是均检漏 条件、检漏方法、检漏人员等密切相义的。不同的测试人员或采用不同的检漏力 法、不同的简漏设备所得到的测试结果往往不一致。因而,文献对系统和没备的 紧密相:作了较为严格的定义:“在某一特定的操作条件下,采用指定的、具有 相应测试分辨率的检漏方法测得的泄漏率低于某一规定的指标泄漏率。满足上述 条件的系统和设备是紧密的,反之是不紧

It is well known that the raw material belt is used to seal the connection of the pipeline, so that the sealing of the pipeline is better, and leakage can occur if the seal is not good. At present, leakage is a common phenomenon in nature. Daily life such as running water, gas leakage often brings people inconvenience and even harm; In industry, such as pressure vessels, pipelines, reactors, valves, hydraulics, and when the means of transportation leak, it will cause a large amount of waste of energy and raw materials, and equipment can not be properly done. Heavy causes equipment scrap, complete plant or system paralysis, casualties and serious environmental pollution. Therefore, people try their best to prevent and eliminate leakage in production practice. Sealing refers to the fact that there is no leakage at the connection of the machine and equipment. The parts that can be used for sealing are called seals. More complex sealing connections are called sealing systems or sealing devices. Commonly used sealing equipment is raw material belt, sealing adhesive, adhesive and so on. In engineering practice, the concept of sealing or tightness is commonly used to evaluate the effectiveness of sealing connections. The compactness of the system and equipment can be determined by the size of the leakage rate. In the physical sense, there is no absolute compact piece. The so-called tightness should be like other physical quantities. It can be measured quantitatively. The tightness of the connection is defined in the literature as: "Under certain operating conditions, the leakage rate of the connection is lower than the leakage rate of a specified target; Or under the specified leakage rate indicator, the connection can withstand specific operating conditions. The connection that satisfies the above conditions is tight, and vice versa is considered not tight. " In fact, the leakage rate of the connection is closely related to leak detection conditions, leak detection methods, leak detection personnel, etc.. The test results obtained by different testers or different leakage detection methods and different leakage devices are often inconsistent. Therefore, the literature defines the tight phase of the system and the lack of: "Under a specific operating condition, the leakage rate measured by the specified leak detection method with the corresponding test resolution is lower than that of a specified indicator. leakage rate. The systems and equipment that meet the above conditions are compact, and vice versa. "
