端盖/堵头

端盖或堵头是一种精密工程部件，设计用于密封喷雾歧管系统的末端，防止流体泄漏，维持系统压力，并保护内部组件免受污染。在流体分配系统中，它作为关键的封闭元件，其中多个喷雾喷嘴沿歧管管道安装。

端盖/堵头通过螺纹、焊接或压缩连接方式在歧管末端形成机械密封。它通过均匀分布应力来承受内部流体压力，同时密封表面通过垫圈、O型圈或金属对金属接触防止泄漏。在喷雾系统中，它通过提供封闭边界条件确保沿歧管的均匀压力分布。

The end cap/plug creates a mechanical seal at the manifold's end through threaded, welded, or compression fitting methods. It withstands internal fluid pressure by distributing stress evenly across its structure, while sealing surfaces prevent leakage through gaskets, O-rings, or metal-to-metal contact. In spray systems, it ensures uniform pressure distribution along the manifold by providing a closed boundary condition.
