Description

Výhoda je ešte výraznejšia pri aplikácii vynálezu u armatúr alebo zariadení ktoré sú spravidla opatrované prírubami. Odliatky telies sa zjednodušia a hmotnosť odliatkov sa zníži.The advantage is even more pronounced when applying the invention to fittings or devices which are generally provided with flanges. Solid castings are simplified and cast weight is reduced.

Prírubový spoj podľa vynálezu sa chová ako pružný kĺb a umožňuje prispôsobenie uhla vychýlenia potrubia v prípadoch zmeny polohy potrubia v dôsledku sadnutia pôdy, zemetrasení atd., čím sa eliminuje prídavné ohybové namáhanie prírubového spoja.The flange joint according to the invention behaves like a flexible joint and allows the angle of deflection of the pipe to be adjusted in the event of a change in the pipe position due to soil settlements, earthquakes, etc., thus eliminating the additional bending stress of the flange joint.

Príruba 5 je opatrená guľovou plochou 3 a prechodom 10.In FIG. 4 shows a flange joint applied in pipe distributions consisting of pipes 1 and 2 in which a nut 14 and a flange 5 provided with a thread for screwing into the nut 14 are used as the clamping joint. The flange 5 is provided with a spherical surface 3 and a passage 10.

Na Obr. 5 je zobrazený prírubový spoj u ktorého príruba 5 je riešená ako skrutka zaskrutkovaná do telesa 12 armatúry alebo zariadenia. Príruba 5 je opatrená prechodom 10 a guľovou plochou 3.In FIG. 5 shows a flange joint in which the flange 5 is designed as a screw screwed into the body 12 of the valve or device. The flange 5 is provided with a passage 10 and a spherical surface 3.

Na Obr. 6 je zobrazený prírubový spoj u ktorého príruba 5 sa vkladá do telesa 12 a voči uvoľneniu je poistená poistným krúžkom 15. Počas montáže sa pružné tesnenie 6 stlačí prírubou 5 a príruba 5 poistí poistným krúžkom 15 . Zvieranie spoja je zabezpečené pružnosťou tesnenia 6.In FIG. 6 shows a flange connection in which a flange 5 is inserted into the body 12 and is secured against release by a circlip 15.
