A composite sleeve for surrounding a polymeric cylinder of a self sealing vessel assembly for high pressure microwave assisted chemistry includes at least one wound fabric layer in which the winding is selected from the group consisting of filaments and yarns. The vessel assembly includes a polymeric cylinder and a circular polymeric cap for the cylinder, the cylinder being closed at one end and open at the other end to receive the cap. The open end of the cylinder has a lip that is beveled inwardly from the open end, and the circular polymeric cap has a beveled lower edge that engages the beveled lip when the cap is place upon the polymeric cylinder. For high pressure applications, a choke cylinder depends from the beveled lower edge of the cap, and has an outer diameter substantially the same as the inner diameter of the polymeric cylinder so that the choke provides a self sealing mechanism for the cylinder as pressure from a chemical reaction.increases in the cylinder. A supporting frame extends along the cylinder and across the lid and across the closed end of the cylinder, and prevents the lid from being displaced from the cylinder when pressure is generated inside of the vessel.
L'invention porte sur un réservoir auto-obturant pour applications chimiques utilisant les micro-ondes. Le réservoir (10) comprend un cylindre (12) de polymère fermé à une extrémité et ouvert à l'autre et un bouchon (13) rond de polymère fermant l'extrémité ouverte. L'extrémité ouverte du cylindre (12) présente une lèvre (20) biseautée s'évasant vers l'extérieur et le bouchon (13) un bord (21) inférieur biseauté venant au contact de la lèvre (20) du cylindre (12). Pour les applications à haute pression, il est prévu à la base du bouchon (13) une excroissance cylindrique (22) dont le diamètre extérieur est sensiblement égal au diamètre intérieur du réservoir et qui assure l'auto-obturation alors que croît dans le réservoir la pression due à la réaction chimique. Un manchon de sûreté composite entourant le cylindre (12) comporte au moins une couche de tissu (24) enroulé dont les enroulements peuvent être faits de filaments ou de fils. Un cadre (14) support, qui s'étend longitudinalement le long du cylindre (12) et transversalement au niveau de la base du réservoir et du bouchon (13), maintient le bouchon (13) sur le cylindre (12) pendant que la pression s'établit.
