Definitions

  • TITLE AUTONOMOUS ELECTRONIC MONITORING SYSTEM FOR PURGERS, VALVES AND INSTALLATIONS IN REAL TIME.
  • the present specification refers to an Invention Patent corresponding to a new prototype of autonomous electronic monitoring system for traps. Valves and installations that can be applied to the remote control of Fleets in all kinds of installations and especially to the control of operation of all types of traps and to the detection of steam leaks in real time in said elements
  • Another way of controlling steam leaks and operation of traps consists of the installation of fixed passive elements such as peephole detectors or conductivity measurement that are installed in line in front of the traps, and detect the passage of steam through them. These elements require the help of expensive external detection and analysis elements powered by auxiliary energy, which require expensive installation and, above all, require human intervention for their operation. Being elements installed in line with the trap requires maintenance and failure causes the installation to stop for verification and repair.
  • SUBSTITUTE SHEET (RULE 26)
  • the new prototype of the autonomous electronic monitoring system for traps, valves and installations can be applied to any type of valve or installation or to any type of steam trap and satisfactorily solves all the problems and inconveniences presented by the systems described in the current state of the technique due to the fact that it is an autonomous active system, without auxiliary energy, which is not installed in line with the trap but is installed on the trap itself, but as an independent element of it. so that the system can be removed from the trap without interrupting or modifying its operation. It continuously monitors the operation of the trap, remaining permanently ac or without power consumption and in an alert state, detecting and warning in real time of any steam leakage that occurs through the trap
  • the new prototype object of this invention provides one or more of the following types of information: optical, acoustic or numerical encoded.
  • the optical information consisting of an indicator that can present various states (off, flicker, on and ordinal) depending on the state of the fluid in the trap or in the installation.
  • the acoustic information identifies the same states as the optical information by means of an audible tone system
  • the encoded numerical information contains the same information as the previous ones and additionally an identification code of the trap or installation point where the fault has occurred, being at its Once sent remotely to an optional control receiver for further analysis and treatment
  • the new prototype object of this invention represents a great economic importance for four fundamental reasons: a) Great energy savings by locating and identifying steam losses in real time b) Great reduction of maintenance costs in traps because the early detection of Failure of a trap prevents the total internal destruction that occurs through the passage of continuous steam through it. c) Prevents pressure on condensate return manifolds caused by leaks
  • the new prototype object of this invention consists of three basic elements: a tnple sensor, an electronic analyzer and an optional receiver.
  • Figure 2 represents a prototype of the new autonomous electronic monitoring system for traps. valves and installations, which can be applied to any element or accessory of the installation
  • the multiple sensor is formed by a thermocouple that captures the temperature of the fluid, an electrode that measures the conductivity of the fluid, and a probe that captures the fluid pressure
  • the multiple sensor captures ultrasound produced in the valve or in the installation, without the fluid being in contact with the sensor
  • the multiple sensor is housed in a threaded metal body that connects to the pipeline or the valve body or the momto ⁇ zar trap.
  • the multiple sensor is leak-proof of the fluid, so once mounted it does not affect the normal operation of the installation, valve or trap.
  • Said multiple sensor is electrically and thermally isolated by a ceramic element or of any other nature to prevent heat from being transmitted to the electronic analyzer.
  • the electronic analyzer consisting of: a) Power supply system using batteries and photovoltaic cells is connected to the top of the multiple sensor b) Electronic analysis and control circuits.
  • SUBSTITUTE SHEET (RULE 26) c) Optical and / or acoustic and / or numerical indication systems.
  • the entire analyzer is protected from the outside by a transparent cuvette.
  • the analyzer can be deactivated at will while it is not installed without internal manipulation. Once activated, the system is put on an alert state generating the information of at least one, or all, of the types already described in correspondence with the different possible states of the fluid parameters.
  • the electronic analyzer works with a practically negligible current intensity to ensure safety in the facilities
  • the receiver remotely captures the encoded numerical signals emitted by the analyzer, centralizing and processing said information according to the user's needs.
  • the new prototype object of this invention can also work with total success without the help of the receiver.
  • the identification of the steam loss trap is only one or more of the three types of information already indicated: visual, acoustic and numerical. Even in this case, no additional detection means or auxiliary equipment are required for the immediate location of steam leaks.
  • the new prototype object of this invention has a special interest in the monitoring and continuous monitoring of steam leaks in any type of traps.
  • two examples of application to two different types of traps are shown in Figures 3 and 4, which can be extended to any other type of steam trap.
  • the optional remote receiver is dispensed with.
  • Figure 3 shows the new prototype object of this invention applied on the cover of a bimetallic thermostatic trap.
