Abstract

761,977. Valve accessories. SAUNDERS VALVE CO., Ltd. June 9, 1954 [June 9, 1953]. No. 15882/53. Class 135. A rotary, spherical plug cock has seating rings 13 supported in the casing by flexible diaphragms 14 and counterbored at 16 so that fluid pressure has access to the plug sides of the rings to provide a resultant thrust in opposition to but less than the pressure of springs 17 which are housed in pockets 18 in metal rings 19. Fluid pressure on the major part of the diaphragms is rendered ineffective by washers 15. Excessive pressure on one side of the valve can force its way between the corresponding seating ring and the plug to the central valve chamber whence it can escape by displacing the diaphragm on the low pressure side of the valve. Specifications 571,285 and 655,078 are referred to.
