Abstract

The combination of a strainer, filter and expansion tank in a liquid Cooling system is provided. In some cooling systems, the strainer and filter are separate units usually located in the piping between the expansion tank and the liquid pump. In order to change or clean the strainer or filter, it is necessary to provide valving on either side of the unit such that the liquid flow can be interrupted while the unit is removed. Considerable leakage is involved in making the change and that it is necessary to bypass the whole unit with piping and a valve arrangement in order to maintain the liquid flow during the removal.

Combination Expansion Strainer Filter Tank

The combination of a strainer, filter and expansion tank in a liquid Cooling system is provided. In some cooling systems, the strainer and filter are separate units usually located in the piping between the expansion tank and the liquid pump. In order to change or clean the strainer or filter, it is necessary to provide valving on either side of the unit such that the liquid flow can be interrupted while the unit is removed. Considerable leakage is involved in making the change and that it is necessary to bypass the whole unit with piping and a valve arrangement in order to maintain the liquid flow during the removal.

Strainer-filter element 12 is located within expansion tank 14 of the cooling system. The combination of element 12 and tank 14 has several advantages. Element 12 can be considerably larger than the diameter of the normal piping 16 associated with the cooling system. Thus, the resistance to the liquid flow caused by element 12 can be minimized. Element 12 is provided with elongated handle 18 so that it can be easily removed from the top of tank 14.

The arrangement does not require breaking into a pressurized part of the cooling loop to remove element 12 since open tank 14 is at atmospheric pressure. There are no pipes to break and no liquid leakage when removing element 12. Actually, the screen is a filter when it contains temporary filter material, usually at the startup of the installation when a filter i...
