Täyttöventtiili

Täyttöventtiili is a Finnish term that translates to "filling valve" or "fill valve" in English. It refers to a device used to control the flow of liquid into a container or system. These valves are common in various applications, including plumbing, industrial processes, and everyday household items.

The primary function of a täyttöventtiili is to open and allow liquid to enter when needed and to close automatically or manually to stop the flow once a desired level is reached or the filling process is complete. Different types of täyttöventtiilit exist, varying in their operating mechanisms. Some are operated by mechanical floats, which rise with the liquid level and trigger the valve to close. Others might be pressure-activated or electronically controlled.

In domestic settings, a common example is the täyttöventtiili found in a toilet cistern. When the toilet is flushed, the water level in the cistern drops, causing the float to descend and open the filling valve. As water fills the cistern, the float rises, eventually shutting off the supply of water. Industrial applications for täyttöventtiilit are diverse, ranging from controlling the filling of chemical tanks to managing water levels in boilers and cooling systems. The design and material of a täyttöventtiili are chosen based on the specific liquid being handled, the required flow rate, and the operating pressure and temperature of the system.
