Title
(EN) ROTATABLE BALL VALVE WITH AXIAL DISPLACEMENT ACTUATING STEM
(FR) ROBINET À TOURNANT SPHÉRIQUE AVEC TIGE D'ACTIONNEMENT À DÉPLACEMENT AXIAL
Abstract
(EN)
Valve (1) for controlling fluid flow with a valve ball (66) rotatable between an open position allowing fluid flow and a closed position in which a sealing surface in sealing contact with the entry port (3), exit port (4) or both blocks fluid flow. A valve ball actuating stem (10) is guided relative to the valve body (2) for axial guided movement and has a valve ball engagement section with actuating surfaces of helical shape so that axial displacement of the valve ball actuating stem (10) causes rotation of the valve ball (66). The guide strip members (71, 72) and the valve body (2) have complementary shapes mechanically guiding the guide strip members in the longitudinal direction thereof. One or more locking members (88) is/are provided for blocking dislodgement of the guide strip members in the longitudinal direction.
(FR)
L'invention concerne un robinet (1) destiné à commander l'écoulement d'un fluide doté d'une bille de robinet (66) pouvant tourner entre une position ouverte permettant l'écoulement d'un fluide et une position fermée dans laquelle une surface d'étanchéité en contact étanche avec l'orifice d'entrée (3), l'orifice de sortie (4) ou les deux bloque l'écoulement de fluide. Une tige d'actionnement de bille de robinet (10) est guidée par rapport au corps de robinet (2) pour un mouvement guidé axial et comporte une section de mise en prise de bille de robinet avec des surfaces d'actionnement de forme hélicoïdale de telle sorte qu'un déplacement axial de la tige d'actionnement de bille de robinet (10) provoque une rotation de la bille de robinet (66). Les éléments bande de guidage (71, 72) et le corps de robinet (2) ont des formes complémentaires guidant mécaniquement les éléments bande de guidage dans la direction longitudinale de ces derniers. Un ou plusieurs éléments de verrouillage (88) sont prévus pour bloquer le délogement des éléments bande de guidage dans la direction longitudinale.
