The diaphragm-controlled anti-siphon device prevents the entire quantity of fuel oil from escaping from the tank unnoticeably <strong>without auxiliary energy<\/strong> in the event of leaks in the line of fuel oil consumer installations. Without a safety device against siphoning, environmental hazards and considerable material damage would be the consequence.<\/p>\n<h2 style=\"text-align: left;\">Function of a diaphragm-controlled anti-siphon device<\/h2>\n<p style=\"text-align: justify;\">The switched on fuel oil feed pump generates a <strong>vacuum in the suction line<\/strong>. The vacuum causes a position change of the diaphragm, which in turn opens a sealing element. The fuel oil can now flow from the tank to the burner. If the pump no longer generates a vacuum or if the piping is leaking, the anti-siphon device closes and prevents the tank from draining.<\/p>\n<p><iframe title=\"Funktionsbeschreibung der membrangesteuerten Hebersicherung\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/XY8nFCz1l8I?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h2 style=\"text-align: justify;\">Alternative<\/h2>\n<p style=\"text-align: justify;\">An alternative to the diaphragm-controlled version is the <a href=\"https:\/\/www.gok.de\/HS-MV-Anschluss-Set-7-polig-Kabel-4-m-1321200?search=hebersicherung\" target=\"_blank\" rel=\"noopener noreferrer\">solenoid valve anti-siphon device<\/a>.\u00a0By means of a solenoid valve, the safety device blocks the oil line when the burner is at a standstill and is normally closed.
