How Float Balls Work
Hollow space or solid filled materials that are suspended at the end of a lever in a cistern, tank or a boiler that mostly used to regulate the level of a liquid and mostly water are generally referred to as float balls. When purchasing float balls, different shapes are available in the market where one can select from including spherical or cylindrical shapes. Float balls which have a hollow space inside helps enhance their buoyancy in water or any other liquid so as to determine the liquid level. Float balls that have been filled by solid material made of plastic or other material whose density should be lower than that of the liquid to enhance buoyancy are also used to determine the liquid level. The floats balls mechanisms can also be utilized in other mechanisms to monitor the fluid level such as the switch mechanisms as well as translucent fluid-tubes. A major principle that is applied in all types of float balls is the buoyancy principle where different densities between the float ball and the fluid helps in controlling and monitoring the fluid level.
There is a major type of float ball referred to as stainless steel float balls. Stainless steel is basically manufactured in such a way that it is combined with another metal called chromium in a quantity of about 10% which is hard and brittle metal and able to resist tarnishing and high temperatures because of its very high melting point. In a situation where ordinary steel is used together with stainless steel, the ordinary steel would turn out to be very rusty as well as easily corroded which is not the situation with stainless steel. 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 use of stainless steel float balls in monitoring the fluid levels is possible because they are quite strong and highly durable as well as they are able to resist corrosion. 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. The float ball mechanism is made up of the float ball, a valve and a stem which connects the float ball to the valve. Valves are important as they stop the flow the liquid into the cistern, tank or a boiler as the stem rises and creates a tight seal. Once the fluid is emptied from 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.
