Control Device For A Liquid Level Maintaining System Or The Like
US Patent:
4258745, Mar 31, 1981
Filed:
Mar 12, 1979
Appl. No.:
6/019659
Inventors:
Dean Nicholson - Lakewood CO
International Classification:
F16K 31126, G01F 2320, G05D 902
US Classification:
137403
Abstract:
A control for a liquid level regulating system including a casing which is immersed in the liquid to a depth at which control is to be effected, a loose flexible diaphragm closes the casing at the bottom and is moved in accordance with the liquid head. A plunger mounted in the casing for free vertical movement within a selected range has a disc-like foot positioned for free engagement by the diaphragm. An adjustable spring and stops are provided for setting the range of movement. Vertical movement of the plunger actuates a cam or screw to vary the setting of the control element of the level control system. This element may be the discharge outlet control. The control provides quick response and actuates the level control to effect accurate maintenance of the required liquid level in an air pressure control system or, for example, a variable resistance control in an electrical control system.
