Problems solved by technology

Therefore, complex and relatively expensive valve embodiments are known from the prior art, which prevents the use of these valves as disposable valves
On the downside, however, multiple uses of these valves require high cleaning costs

Embodiment Construction

[0021] exist figure 1 A valve 2 , shown for example in relation to a device 1 for high performance liquid chromatography (HPLC), is connected to a plurality of hoses 3 , 4 , 5 , 6 and 7 . For this purpose, the valve 2 has a plurality of liquid connections 3', 4', 5', 6', 7' and 7'' arranged on the housing 8. A valve body 9 mounted movably relative to the housing 8 is arranged in the housing 8, as in figure 2 as can be seen in the . For example, a hose 5 connected to a waste container 5'' is also provided. The liquid ports 3', 4', 5', 6', 7' and 7'' can be selectively connected based on the relative positions 9', 9'' of the valves, wherein figure 1 A relative position 9' is seen in and can be found in figure 2 See another relative position 9'' in . The relative position 9'' is necessary in order to be able to feed the sample flowing through the hose 6 to the loop line 7 ("loading"). For this purpose flow channels 10 , 11 , 12 are created between the respective liquid co...

Abstract

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).

Description

technical field [0001] The invention relates to a valve, in particular a sampling valve, for a device for synthesis purposes, analysis purposes and / or separation purposes, with at least three liquid connections, with a housing as a valve part and with As a further valve part there is a valve body for the selective connection of a liquid connection to at least one flow channel which is at least partially delimited by a sealing surface between housing and valve body, wherein , the housing and / or the valve body are mounted movably relative to one another. Background technique [0002] For sample separation devices, for example HPLC (High Performance Liquid Chromatography) devices, it is known to use a valve, in particular a sampling valve (DE 10 2008 042 252 A1), for the selection of different chromatography columns of the flowing sample phase. Here, the pump generates pressures of up to 1000 bar for the movement of the mobile phase, so that the injection valve must meet extre...
