Abstract

911,986. Valves. NEUE ARGUS G.m.b.H. Aug. 30, 1960 [Oct. 28, 1959], No. 29936/60. Class 135. A shut-off cock having a spherical plug 4, Fig. 2, is provided with piston-type packing rings 11 in the inlet and outlet passages, housed in a recess of the housing or the fluid connection 2. The sealing between the pistontype packing and the recess is provided by two plastic wedge rings 8 loaded by springs 9 and the pressure of the flowing medium. Pressure rings 7 are provided between the springs and the wedge rings. An intermediate ring 12 may be inserted between the wedge rings having inclined surfaces at the same angle as the inclined surfaces of the rings. In a modification this ring 12 is omitted and the inclined surfaces of the wedge rings are in direct contact. In a further modification, shown in Fig. 4, the wedge rings 14, 15 are of triangular cross-section and pressure rings 13 press these rings into sealing contact with the piston-type packing 11 and the recess. A similar type of seal is provided for the valve spindle 5, Fig. 5, by a wedge ring 8 and a pressure ring 7 loaded by springs 9.
