4379582 CAP For HITACHI ZX330-3 6HK1

A CAP, often referred to as a plug, end cap, or sealing cap, is a closure component designed to seal or cover the open ends of pipes, tubes, valves, or other equipment. These caps provide a protective barrier, preventing dirt, debris, moisture, or chemicals from entering the system. They also help maintain internal pressure and prevent the escape of gases or liquids. Caps come in various materials such as plastic, rubber, metal, or silicone, and can be used for temporary or permanent sealing purposes.

CAP, commonly called head. Head refers to the component used to seal the end of the container to isolate the internal and external media, also known as end cover. The head of cylindrical container is generally a revolving shell. According to the shape of the head surface, it can be divided into convex, conical, flat and combined shapes. Convex head refers to the head whose outer surface is convex, such as hemispherical, oval, dish-shaped and flangeless spherical head. Some gas cylinders adopt a combined bottom head with inward convex surface, which can not only ensure the strength, but also meet the requirements of safe use. CAP plays a vital role in the pipeline system, ensuring the tightness and safety of the pipeline.

Cap, also known as cap, head, cap, cap and plug, is a kind of pipe fitting used to close the pipeline. It is usually welded to the pipe end or installed on the external thread of the pipe end to cover and plug the pipe. The plug, which has the same function as the pipe plug, is a component used to close the opening of the pipe or container, and its main function is to prevent liquid, gas or solid substances from leaking from the pipe or container. As an important pipeline sealing component, the plug has a wide range of application scenarios and a variety of material choices, ensuring its effective use in various environments.

CAP is a common physical isolation method, which can effectively control the flow of liquid and gas. The main function of the plug can divide the pipeline into two parts and prevent the mixing of fluids on both sides. This isolation can be used for sample analysis and storage in the laboratory and for controlling the movement and mixing of fluids in industrial production. The plug can close the passage of the pipeline, thus preventing the flow of fluid. This closing function can be used when it is necessary to stop the flow of fluid, such as pipeline maintenance or equipment replacement in an emergency. The principle of the plug is mainly to control the movement and mixing of fluid through the plunger or filler near the pipe mouth. When the plug is inserted into the pipeline, the flexible part perpendicular to the pipeline axis can adapt to the diameter and shape of the pipeline, and the plug is closely attached to the inner wall of the pipeline, thus realizing the functions of leakage prevention, blockage and flow control.
