The invention is intended to bring about a weaentliobmlnable solution

Invention company will have a butterfly valve with one on the Edge of the YersehluEseheibc all-round hat vargeaohlagen This hat forms a »between two spaces delimited by the bands of the washer resting against the sealing ring» in which leakage fluid can enter in the event of leaks «

The butterfly valve according to the invention is further characterized by the passages of the axle ends on both sides the sealing ring and the flanges the housing arranged radial bores "through the bulges in the anaats" turn off the Aehsendan & eskbsr are »

Ss also belongs to the invention, in the bores of the Attach tight tubular hanger ·

Through the bores, the sioh can accumulate in the hat Liquid come out "The small tubes in the bores of the sealing ring ^ tomorrow for that" so that the bores at Compress the seal remains open

The housing of the butterfly valve consists of two identical halves of the house. 1, which are assembled with flanges 2 · On both sides of the seam between the two flanges 2 there is a · circumferential hat »in which a sealing ring 3 is inserted. The flanges 2 have opposite bores 4 in which the axle ends $, 7 attached to the locking disk 5 are inserted the sealing ring 3 and the two housing housings against each other wi * «αόα dwi JzumSSSüSm « SS housing against the emerging axle ends 6 ₉ 7.

The Yerschlufiseheibe 5 is provided at the band with an encircling hat 8 * which interrupted by the axle ends 6 _f 7

The edges 9, 1o of this groove 8 are in the final position on the sealing ring 3 and form two in the flow » direction of one behind the other seals with an intermediate space, in which calibration can collect any leakage fluid

So that this leakage fluid can escape from the gap, are in the sealing ring 5 and the flanges 2 of the Housing 4 holes 4 for the axle ends on both sides outside open bores 11 arranged «which in the seal · * · sing 3 are stiffened by tubes 12 *
