Definitions

  • the air-gas regulating system adjusts the speed of the vent depending upon the needs of the installation for heat.
  • a multifunctional gas valve delivers the correct amount of gas for the correct combustion value, which is controlled by the ionization electrode.
  • the weak areas of this kind of system are as follows: the complexity of its construction, the need for many parts, springs, openings, a membrane, the need to calibrate the system, and hysteresis generated by the magnet modulating between the rising and falling current.
  • the valve we are proposing is composed of a body, normally made of aluminum, together with the usual parts for connections and for detecting the input and output pressure, a magnetic safety valve suitable for the category of the application requirements, and a second safety and modulation valve.
  • This valve is special because it is controlled by an impulse linear motor, for example 0.1 - 0.2 mm per pulse. The linear motor opens and closes the valve at each pulse received, and safety is an integral feature: upon the appropriate command or if there is no current, it automatically shuts off the gas valve.
  • a differential analog switch detects the quantity of air for combustion, and by referencing this value, using the above valve we can consistently measure out the quantity of gas required (thermal output) without having to worry about variables in the gas, such as its thermal output (for the same family of gases), or upstream pressure.
  • the amount of gas being delivered by the valve will always comply with requirements.
  • the modulation process is very precise, and there are no errors due to hysteresis.
  • a multifunctional gas valve composed of an electromagnet valve and an impulse linear motor valve.
  • modulating the gas, stabilizing gas pressure when the pressure upstream varies, regulating the delivery of gas if the type of gas from among the different groups of gases within the same family varies this system is also innovative in that it is simple to build, requires no calibration, and the minimum and maximum limit values detected by the differential analog switch and stored in the memory of the microprocessor are sufficient for delivering the correct amount of gas at the maximum and minimum values.
  • This gas valve is built like the previous valve, except that it has a pressure sensor at the output of the valve itself. It is this pressure sensor which determines the quantity of gas to be modulated, still by means of the impulse linear motor. The pressure sensor controls modulation within the required parameters, which are managed by a microprocessor, for example.
  • This valve can also be used on natural draft boilers (which do not have a vent and differential analog switch). Using pressure as the reference parameter, the valve cannot regulate the delivery of heat if the calorific value of the gas varies.
