Definitions

  • the invention relates to a method of controlling a pressure in a chamber, containing a liquid or gaseous fluid.
  • Controlling the pressure of a liquid or gas contained in a chamber is performed by adjusting a flow section.
  • the magnitude of this flow section is dependent on the pressure of the fluid contained in the chamber and on the magnitude of an adjustable spring tension.
  • An example of this is a reduction valve.
  • a disadvantage of this known method is the fact, that a variation of the selected pressure is only possible by varying the spring tension. Expensive control members are required when applying this method in an automatic control system.
  • the invention has the object of reducing the disadvantages of the known method.
  • said chamber comprises at least one supply or discharge member, which is frequently opened and closed alternatively.
  • the pressure prevailing in the chamber can be increased or decreased.
  • the frequency of opening and closing and/or the duration of opening said member can be selected in dependance on the prescribed pressure.
  • the method according to the invention can be used with burners, in which the amount of gaseous or liquid fuel per unit of time supplied to the burner is controlled.
  • the heat per unit of time delivered by the burner can be controlled exactly by controlling the pressure in the ) chamber in dependance on the temperature which is decisive for the produced heat.
  • the invention will be illucidated with reference to the accompanying scheme.
  • the measured value of the process 1 to be controlled e.g. a gas burner
  • a temperature sensor 2 The difference between this measured value and a value adjusted by means of a manually operated adjusting member 3 is supplied to a modulator 4 generating the signals for controlling the supply member 5.
  • a pressure In the chamber 6 a pressure will be obtained which is decisive for the amount of gas per unit of time flowing through the nozzle 7 of the burner.
  • the chamber 6 may have an outlet with a fixed cross section. A flow having a selected amount per unit of time flows through this outlet. This selected amount is the determined amount required for producing the required quantity of heat for the process1. This amount per unit of time is dependent on the selected pressure in the chamber 6 when having a constant flow section of the outlet.
  • the pressure in the chamber 6 is determined by the amount of fluid supplied to the chamber 6 through the supply member 5 constituted by a control member.
  • This control member 5 is a valve which is periodically completely opened and completely closed. The amount of fluid per unit of time is adjusted by selecting the frequency of opening and closing this valve during a determined period of time or by selecting a period of time during each cycle of opening and closing the value when operating .the valve with a fixed frequency.
  • the outlet of the chamber 6 may have an adjustable flow section.
  • the supply member 5 may consist of a pump, e.g. a plunjer pump, the number of strokes per unit of time and/or the output per stroke being adjustable.
  • a pump e.g. a plunjer pump
  • the chamber 6 preferably comprises a cushion of air or gas constituting a spring.
