Valve Alarm Unit

 

Medical gases valve alarm is a machine that monitors the pressure in the medical gases pipelines within medical centers and in case of a decrease in pressure, complications in the pipelines, or if the gas flow is completely blocked, notifies the person in charge or the facility engineering team of this matter in the hospital both through auditory and visual signals.

The copper cables which carry the medical gases or vacuum, before entering the medical center, should go through this box and there is some gas valves incorporated within this machine at the way of the pipelines so that they can limit the gases’ direction only to the desired location.

Of the safety benefits of these boxes, one can refer to the flexible ports that have been incorporated within the sight glass of the gas valves which affords us the ability to shut off the gas valve and block the pipeline. This port cannot be placed in its original place anymore due to the gas valve handle that is raised. Therefore, because of the raised gas valve handle, the personnel in charge at any hospital unit shall know that the pipeline has been shut off.

 

Introduction: How does the Valve Alarm Work?

---

After the unit has been properly installed, the green light shall always remain on. When the pressure for any of the following gases such as Oxygen, compressed air, and Nitrogen Oxide decreases to less than 2 bars and for the vacuum to less than 0.2 bars, or if the flow for any of the aforementioned gases is blocked, the visual alarming signal (the word “Low” will be exhibited in front of the specified gas) and the auditory alarming signal (the siren) shall go off. If you press

the silent button, the auditory alarm shall go off for 2.30 to 3 minutes; however, the visual alarm shall remain on till the issue that has been caused by the machine is resolved. If the pressure of any of the gases of Oxygen, compressed air, and Nitrogen Oxide rises to more than 3.8 bars and vacuum to more than 0.2 bars, both auditory and visual alarming signals shall go off. It should be noted that the aforementioned procedure shall be observed in case of all emergency situations.
