    • The invention relates to a valve, in particular a sample injection valve, for a device (1) for synthesizing, analyzing, and/or separating, comprising at least three liquid connections (3', 4', 5', 6', 7', 7"), a housing (8) as a valve part, and a valve body (9) as another valve part for selectively connecting the liquid connections (3', 4', 5', 6', 7', 7") by means of at least one flow channel (10, 11, 12) bounded at least partially by sealing surfaces (10', 11', 12') between the housing (8) and the valve body (9), wherein the housing (8) and/or the valve body (9) are supported in such a way as to be movable relative to each other. In order to a create a one-way valve, at least one valve part (8 or 9) adjacent to the sealing surface (10', 11', 12') and made of a plastic material can be plastically deformed according to a relative position (9'), in particular of the valve body (9), in order to be able to withstand the elevated pressure loads in the flow channel (10, 11, 12) in a liquid-tight manner in said relative position (9'), in particular of the valve body (9).
    • 本发明涉及用于合成,分析和/或分离的装置(1)的阀,特别是样品注射阀,其包括至少三个液体连接(3',4',5',6',7 ',7“),作为阀部的壳体(8)和作为用于选择性地连接液体连接(3',4',5',6',7',7')的另一个阀部分的阀体 “)通过至少部分地由壳体(8)和阀体(9)之间的密封表面(10',11',12')限定的至少一个流动通道(10,11,12) 壳体(8)和/或阀体(9)以相对于彼此可移动的方式被支撑。 为了形成单向阀,与密封表面(10',11',12')相邻并且由塑料材料制成的至少一个阀部件(8或9)可以根据相对位置塑性变形 (9'),特别是阀体(9),以便能够以相对位置(9')以液密方式承受流道(10,11,12)中的升高的压力负荷,特别是阀体(9) ),特别是阀体(9)。
