PTFE sealing ring

PTFE-Protection & Sealing Ring For manhole openings with sealing cover. Situation Summary The enamels in enamelled reaction and agitator tanks are shock and impact sensitive. By impact or impact, the enamel layer flakes off easily, often requiring very expensive repairs or re-enameling of the entire boiler. In particular, the inner sides of manhole, filling and sampling nozzles are endangered, since impact and impact stress can not be ruled out during manipulation with the lid open. To reduce the risk to the container has therefore been used structures according to Figure 1 above. Between the nozzle opening (1) and cover (2) there is an enamelled steel intermediate ring (3), which is sealed on both sides by means of seals (4) to the detail "A" against nozzle and cover. A disadvantage of this embodiment is that opposite the enamelled steel intermediate rings the aforementioned stresses are also sensitive and unusable can be no protection of the socket inside present When applying a vacuum, the upper Seal slightly buckled and leaking a more frequent change of the upper seal with frequent opening of the lid (sampling, Addition of feedstock and additives) was required. To eliminate the disadvantages, IDT offers an intelligent solution that works without intermediate rings and gaskets applied on both sides, is functionally reliable and has a high degree of sealing quality. Troubleshooting Essential elements of the new seal design are a base body (5) with incorporated on the inner shell circumferential groove and a retracted apron (6).
