Title (EN) PRESSURE CONTROL VALVE AND SUPERCRITICAL FLUID CHROMATOGRAPH
(FR) VANNE DE RÉGULATION DE PRESSION ET CHROMATOGRAPHE À FLUIDE SUPERCRITIQUE
(JA) 圧力制御バルブ及び超臨界流体クロマトグラフ
Abstract:
(EN) A pressure control valve of the present invention is provided with a pressure control block. The pressure control block has: an opening that is provided in one outer surface; a pressure control surface that is provided as a flat surface at a bottom portion of the opening; and two internal flow channels, each of which has an end portion opening in the pressure control surface. In the opening of the pressure control block, a sheet-like elastic valve body is provided, said valve body being disposed to cover the pressure control surface. On the side opposite to the pressure control surface with the valve body therebetween, a valve body drive unit is provided, said valve body drive unit adjusting a gap amount between the valve body and the pressure control surface by pressing the valve body to the direction perpendicular to the pressure control surface. The pressure control surface has a hardness that is higher than that of hard materials.
(FR) L'invention concerne une vanne de régulation de pression qui est pourvue d'un bloc de régulation de pression. Le bloc de régulation de pression possède : une ouverture qui est ménagée dans une surface externe ; une surface de régulation de pression qui se présente sous la forme d'une surface plate au niveau d'une partie inférieure de l'ouverture ; et deux canaux d'écoulement internes, dont chacun a une partie d'extrémité donnant dans la surface de régulation de pression. Dans l'ouverture du bloc de régulation de pression, un corps de vanne élastique de type feuille est prévu, ledit corps de vanne étant disposé pour recouvrir la surface de régulation de pression. Sur le côté opposé à la surface de régulation de pression, le corps de vanne étant au milieu, se trouve une unité d'entraînement de corps de vanne, ladite unité d'entraînement de corps de vanne ajustant une quantité d'espace entre le corps de vanne et la surface de régulation de pression en appuyant sur le corps de vanne dans la direction perpendiculaire à la surface de régulation de pression. La surface de régulation de pression présente une dureté qui est supérieure à celle des matériaux durs.
(JA) 圧力制御バルブは圧力制御ブロックを備えている。圧力制御ブロックは、1つの外面に設けられた開口部、開口部の底部に平面として設けられた圧力制御面、及び圧力制御面にそれぞれの端部の開口をもつ2本の内部流路を有する。圧力制御ブロックの開口部内に弾性を有し圧力制御面を覆うように配置されたシート状の弁体が設けられている。弁体を挟んで圧力制御面とは反対側に、弁体を圧力制御面に対して垂直な方向へ押圧することによって弁体と圧力制御面との間の隙間量を調節する弁体駆動部が設けられている。圧力制御面が硬質材料よりも高い硬度を有する。
