卡套接头也是因为其安装简便,抗压力高,故在现代工程作业中得到广泛应用。本篇文章就是关于关于卡套接头的装配问题的介绍。

Bayonet joint is widely used in modern engineering because of its simple installation and high pressure resistance. This article is about the assembly of bayonet joint.

1.禁止加入密封胶等填料。有人为了取得更好密封效果,在卡套上涂上密封胶,结果密封胶被冲入液压系统中,造成液压元件阴尼孔堵塞等故障。

1. Sealant and other fillers are prohibited. Some people in order to achieve better sealing effect, in the card sleeve coated with sealant, sealant was flushed into the hydraulic system, causing the hydraulic components Yin ni hole blocking fault.

2.预装①卡套式管接头的预装的最重要的环节,直接影响到密封的可靠性。一般需要专用的预器。管径小的接头可以在台钳上进行预装。具体做法是,用一个接头作为母体,将螺母、卡套压紧到管子上可。主要有卡套式直通管接头、卡套式端直通接通头、卡套式三通管接头等型式。笔者发现,即使是同一厂家一批货,这几种接头体上锥形孔的深度往往不相同,结果就造成了泄漏,而此问题往往被忽视。正确的做法是,管子一端用什么样的接头体连接,对应的连接端则用相同类型的接头预装,这样能最大限度地避免出现泄漏问题。②管子端面应平齐。管子锯断后应在砂轮等工具上打磨平齐,并且去除毛刺,清洗并用高压空气吹净后再使用。③预装时,应尽量保持管子与接头体的同轴度,若管子偏斜过大也会造成密封失效。④预装力不宜太大使卡套的内刃刚好嵌入管子外壁,卡套不应有明显变形。在进行管路连接时,再按规定的拧紧力装配。ф6-1卡套的拧紧力为64-1 15n、16фmmr 259n、ф18mm的为450n。如果在预装时卡套变形严重,会失去密封作用。

2. Preinstallation card sleeve type pipe joint preinstallation of the most important link, directly affect the reliability of the seal. Special presets are usually required. Smaller joints can be preassembled on a vise. The concrete way is, USES a joint as the matrix, presses the nut, the clamp sleeve to the pipe may. The main types are bayonet type through pipe joint, bayonet type end through connector, bayonet type three-way pipe joint and so on. The author found that, even if the same manufacturer of a batch of goods, these kinds of joint body conical hole depth is often not the same, resulting in leakage, and this problem is often ignored. The correct way is, what kind of joint body is used to connect one end of the pipe, and the corresponding connection end is preassembled with the same type of joint, so as to minimize the occurrence of leakage problems. The end of the pipe should be flush. After the pipe is cut, it shall be polished and leveled on tools such as grinding wheel, and burrs shall be removed, cleaned and blown clean with high-pressure air before use. (3) preinstallation, should try to keep the pipe and joint body coaxial, if the pipe deflection is too large will cause seal failure. (4) preload force should not be too ambassador sleeve inside edge just embedded pipe wall, sleeve should not be obvious deformation. When connecting pipes, assemble them according to the specified tightening force. The tightening force of 6-1 jacket is 64-1 15n, 16 mmr259n and 18mm 450n. If the clamp is seriously deformed during preassembly, it will lose its sealing function.

3.连接管路时,应使管子有足够的变形余量,避免使管子受到拉伸力。

3. When connecting the pipe, the pipe should be provided with sufficient deformation allowance to avoid drawing force on the pipe.

4.连接管路时,应避免使其受到侧向力,侧向力过大会造成密封不严。

4. When connecting the pipeline, it shall be protected from lateral force, which may lead to loose seal.

5.连接管路时,应一次性好,避免多次拆卸,否则也会使密封性能变差。

5. When connecting the pipeline, it should be done in one time to avoid repeated disassembly, otherwise the sealing performance will be poor.
