Description
Technisches GebietTechnical area
Das vorliegende Gebrauchsmuster betrifft vor allem eine In-Line-Kalibriervorrichtung für Pilotventil und Hauptventil eines pilotgesteuerten Sicherheitsventils.Above all, the present utility model relates to an in-line calibration device for pilot valve and main valve of a pilot-operated safety valve.
Technischer HintergrundTechnical background
Beim pilotgesteuerten Sicherheitsventil handelt es sich darum, dass auf dem Körper normales Federsicherheitsventils zusätzlich noch eine Pilotvorrichtung angeordnet wird, umfassend Hauptventil, Pilotventil, Entlastungsventil, Anschlüsse, Rohrleitungen usw. Entsprechend seinem spezifischen Aufbau kann er praktisch nur das Pilotventil einstellen, daher ist Einstellung des Pilotventildrucks die Kerntechnik, eben auch technische Hürde der Pilotventilkalibrierung. Bereits für die Einstellung des pilotgesteuerten Sicherheitsventils muss zuerst das ganze Ventil aus Leitungen oder Behälter entfernt werden, dann zu einer out-line- Kalibrierstelle geliefert und kalibriert werden. Eine in-line-Kalibrierung für pilotgesteuertes Sicherheitsventil ist nicht zu realisieren, ausserdem bedingt durch Beschränkungen der Montage- und Nutzungsbedingung des Sicherheitsventils sind Entfernung, Heben und Installation nach wie vor schwierig, oft Menge Arbeit, hohe Einstellkosten und lange Einstellperiode nicht vermeidbar.The pilot-operated safety valve is designed to additionally install a pilot device on the normal spring safety valve body, comprising the main valve, pilot valve, relief valve, connections, piping, etc. According to its specific structure, it can practically only adjust the pilot valve, therefore setting the pilot valve pressure the nuclear technology, just the technical hurdle of the pilot valve calibration. Already to adjust the pilot-operated safety valve, the entire valve must first be removed from lines or vessels, then delivered to an out-of-line calibration point and calibrated. An in-line calibration for pilot-operated safety valve is not feasible, also due to limitations in the installation and use condition of the safety valve removal, lifting and installation are still difficult, often amount of work, high setting costs and long adjustment period unavoidable.
Inhalt des GebrauchsmustersContent of the utility model
Die Erfindung des vorliegenden Gebrauchsmusters liegt daran, eine neue In-line-Kalibriervorrichtung sowie -Verfahren für Pilotventil und Hauptventil eines pilotgesteuerten Sicherheitsventils anzubieten, um das obengenannte Problem zu lösen. The invention of the present utility model is to propose a new in-line calibration device and method for pilot valve and main valve of a pilot-operated safety valve to solve the above-mentioned problem.
Um das obengenannte Ziel zu erreichen, lautet das Lösungskonzept des Gebrauchsmusters wie folgt: Das vorliegende Gebrauchsmuster offenbart eine in-line-Kalibriervorrichtung für Pilotventil und Hauptventil eines pilotgesteuerten Sicherheitsventils, umfassend pilotgesteuerten Sicherheitsventil, wobei das genannte pilotgesteuerte Sicherheitsventil mit einem Pilotventil, Hauptventil sowie Leitung (
Der Vorteil des vorliegenden Gebrauchsmusters gilt: ohne das pilotgesteuerte Sicherheitsventil zu entfernen können die Druckseinstellung des Pilotventils, gleichzeitige Druckeinstellung des Pilot- und Hauptventils oder Überprüfung des Dichtungsdrucks und der Flexibilität des Pilot- und Hauptventils erfolgen. Die Arbeit bei der Kalibrierung wird erheblich reduziert, insbesondere für die großkalibrigen Sicherheitsventile mit hoher Einbaulage, die Einstellzeit wird verkürzt, es kann unmittelbar beurteilen, ob das Hauptventil bzw Pilotventil ausfällt, leichte Tragbarkeit, genauer und vollständiger Einstellwert, die Kalibrierungsschwierigkeit von Kunden vor Ort wird ausreichend geklärt, die Betriebssicherheit der Unternehmen wird garantiert gewährleistet. The advantage of the present utility model is that without removing the pilot operated safety valve, pilot valve pressure adjustment, pilot and master valve pressure adjustment, or seal pressure and pilot and main valve flexibility can all be controlled. Calibration work is significantly reduced, especially for the large-bore high-level safety valves, the set-up time is shortened, it can immediately judge whether the main valve or pilot valve fails, easy portability, accurate and complete set-point, the on-site calibration difficulty sufficiently clarified, the operational safety of the companies is guaranteed guaranteed.
