Title (EN) INLINE CONTROL VALVE
(FR) VANNE DE REGULATION EN LIGNE
Abstract:
(EN) An inline control valve (20) having a valve stem (24) which extends through the valve body and is perpendicular to the valve bore sleeve (36). The valve stem has a flat stem base (26) located within the valve body. The stem base is located perpendicular to the stem and it has an eccentric pin (28) on the opposite side from stem. The flat stem base and the pin are in constant contact with a valve trim sleeve (30) which has a flat mating surface with a slot to receive the pin. The valve trim sleeve is located around a bore sleeve in the valve body. The valve trim sleeve controls the flow through the valve by blocking or opening flow orifices (42) which are located on the end of the bore sleeve. When the valve stem is rotated, the stem base rotates the eccentric pin. The pin forces the trim sleeve to slide along the bore sleeve and open or close the flow orifices.
(FR) L'invention concerne une vanne de régulation en ligne (20) pourvue d'une tige de manoeuvre (24) qui traverse le corps de la vanne et est perpendiculaire au chemisage de la vanne (36). La tige de manoeuvre comporte un support de tige plat disposé à l'intérieur du corps de vanne. Le support de tige (26) est placé perpendiculairement à la tige et possède un pion excentré (28) sur le côté opposé à la tige. Le support de tige plat et le pion sont au contact permanent d'un manchon réducteur (30) qui présente une surface de contact plane, pourvue d'une fente pour recevoir le pion. Le manchon réducteur entoure un chemisage dans le corps de la vanne. Ledit manchon régule le flux dans la vanne en obturant ou en ouvrant des orifices d'écoulement (42) situés à l'extrémité du chemisage. Lorsqu'on fait tourner la tige de manoeuvre, le support de tige entraîne le pion excentré. Ce pion fait glisser le manchon réducteur le long du chemisage et ouvre ou ferme les orifices d'écoulement.
