Title (EN) MANUAL HIGH-TEMPERATURE AND HIGH-PRESSURE HYDROPHOBIC BALL VALVE HAVING SUPERIOR SEALING PROPERTY
(FR) ROBINET À TOURNANT SPHÉRIQUE MANUEL HYDROPHOBE HAUTE TEMPÉRATURE ET HAUTE PRESSION AYANT UNE PROPRIÉTÉ D'ÉTANCHÉITÉ SUPÉRIEURE
(ZH) 密封性优越式手动高温高压疏水球阀
Abstract:
(EN) A manual high-temperature and high-pressure hydrophobic ball valve, comprising a valve body (7), a ball body (5) and a valve rod (15); the bottom of the valve rod (15) is connected to the ball body (5); a medium inlet and a medium outlet are respectively provided in two sides within the valve body (7); an inlet valve seat (4) is provided in the valve body (7) on the side of the medium inlet; an outlet valve seat (6) is provided in the valve body (7) on the side of the medium outlet; a step having a reduced diameter is provided at one end, closer to the medium outlet, of the outlet valve seat (6); a step hole, matched with the step of the outlet valve seat (6), is provided on the valve body (7); an end surface b on the step of the outlet valve seat (6) and an end surface fitting the step hole of the valve body (7) are slightly match grinded to achieve a full plane, realizing sealing; and an interference fit is formed between a cylindrical surface a on the step of the outlet valve seat (6) and the step hole of the valve body (7).
(FR) L'invention concerne un robinet à tournant sphérique manuel hydrophobe haute température et haute pression, comprenant un corps de robinet (7), un corps de tournant sphérique (5) et une tige de robinet (15) ; la partie inférieure de la tige de robinet (15) est reliée au corps de tournant sphérique (5) ; une entrée de milieu et une sortie de milieu sont respectivement ménagées dans deux côtés à l'intérieur du corps de robinet (7) ; un siège de robinet d'entrée (4) est disposé dans le corps de robinet (7) sur le côté de l'entrée de milieu ; un siège de robinet de sortie (6) est disposé dans le corps de robinet (7) sur le côté de la sortie de milieu ; un gradin ayant un diamètre réduit est ménagé au niveau d'une extrémité, plus proche de la sortie de milieu, du siège de robinet de sortie (6) ; un trou en gradin, correspondant au gradin du siège de robinet de sortie (6), est ménagé sur le corps de robinet (7) ; une surface d'extrémité (B) sur le gradin du siège de robinet de sortie (6) et une surface d'extrémité s'adaptant au trou en gradin du corps de robinet (7) sont légèrement rodées pour obtenir un plan complet, réalisant une étanchéité ; et un ajustement serré est formé entre une surface cylindrique (A) sur le gradin du siège de robinet de sortie (6) et le trou en gradin du corps de robinet (7).
(ZH) 一种手动高温高压疏水球阀,包括阀体(7)、球体(5)和阀杆(15),阀杆(15)底部与球体(5)连接,阀体(7)内两侧分别设介质进口和介质出口,介质进口一侧的阀体(7)内设有进口阀座(4),介质出口一侧的阀体(7)内设有出口阀座(6),出口阀座(6)靠近介质出口一端设有一直径变小的台阶,阀体(7)上设有与出口阀座(6)的台阶相配合的台阶孔,出口阀座(6)台阶上的端面b与阀体(7)台阶孔相贴合的端面相互轻微配磨达到全平面,实现密封;出口阀座(6)台阶上的圆柱面a与阀体(7)台阶孔之间采用过盈配合。
