Szeleptüske

Szeleptüske, often translated as "valve stem" or "valve pin," is a crucial component in many types of valves, particularly those used for gas containment. Its primary function is to act as a movable plug that controls the flow of gas or liquid. In its resting state, the szeleptüske is typically held in a closed position by a spring or other pressure mechanism, preventing the substance from escaping. When activated, usually by an external force like a button or lever, the szeleptüske is pushed or pulled, opening a passage and allowing the controlled release or flow of the substance.

The design and material of a szeleptüske vary depending on its application. For instance, in bicycle tire valves, it's a small, precisely machined metal pin. In industrial gas cylinders, a more robust szeleptüske, often made of brass or stainless steel, is used to withstand higher pressures and ensure a secure seal. The sealing surface where the szeleptüske meets the valve body is critical for preventing leaks. This interface is often designed to create a tight fit, sometimes with the aid of rubber or plastic seals, to maintain pressure integrity. The proper functioning of the szeleptüske is essential for the safe and effective operation of many everyday items and industrial systems.
