Float Ball Working Mechanism
Regulation of a liquid level in a cistern, tank or a boiler such as water is mostly done by apparatus referred to as float balls which can either be having a hollow space or they can be filled with a solid material. Float balls are available in the market in many different shapes such as they can be spherical or cylindrical. The hollow float balls which have air inside helps enhance their buoyancy in water or any other liquid so as to determine the liquid level. Solid material float balls are made of plastic or other material whose density is required to be less than that of water or any other liquid also used for determining the liquid level. Switch mechanisms together with the translucent fluid-tubes can also employ the float ball mechanism in monitoring the fluid level. All the float balls depend on the principle of buoyancy where different densities between the float ball and the fluid helps in controlling and monitoring the fluid level.
Stainless steel float balls is one major type of float balls. Stainless steel is an alloy of steel made up of about 10% chromium which is hard and brittle metal and able to resist tarnishing and high temperatures because of its very high melting point. Stainless steel is preferred to ordinary steel as it does not rust or corrode easily. The use of stainless steel float balls is recommended since they are capable of withstanding very high temperatures and pressures and they are also able to provide maximum buoyancy. The great strength as well as durability of stainless steel float balls together with their ability to resist corrosion makes it possible to use them in controlling and monitoring the fluid levels. Stainless steel float balls are more viable for use in any setting mostly the commercial setting since their great qualities makes them cost efficient.
A float ball mechanism is able to monitor and control the fluid level by having a valve that is able to close the flow of the liquid into the cistern, tank or a boiler once the needed level is attained and is able to work accurately and can also be relied on. A float ball works together with a valve and a stem which connects the float ball to the valve. The flow of the liquid into the cistern, tank or a boiler and the stem rising thus creating a tight seal to stop the flow of a liquid is mainly done by the valve. When the level of a liquid decreases in the cistern, tank or a boiler, the float ball drops opening up the valve allowing more fluid to get in while the float ball rises as the fluid level rises until the required level is attained where the valve closes.
