Embodiment

[0064] Formation of specification trial production based on Table 1 figure 1 Based on the basic structure of the valve device, the sealing performance and durability of the diaphragm were evaluated. Separators of various specifications were trial-manufactured by cross-linking molding using a press machine. In the measurement of the hardness, the A-type hardness measured by a durometer durometer conforming to JIS K6253-3 was measured.

Abstract

This invention provides a valve device. The valve device (1) has: a valve main body (2) that compartmentalizes a valve chamber (21) provided with an NO outflow port (25) and NC outflow port (24) through which a fluid flows; and a valve body (3) that opens / closes the NC outflow port (24) and NO outflow port (25). The valve body (3) includes: a diaphragm (6) disposed in a manner so as to cover the valve chamber (21); and a drive means (4) that, by means of pressing the diaphragm (6), can open / close the NC outflow port (24) and NO outflow port (25). A first valve seat (24b) and second valve seat (25b) are formed at the periphery of the NC outflow port (24) and NO outflow port (25). The diaphragm (6) comprises an elastic material of which the JIS-K6253 durometer A hardness is A50-A85. The pressure of the seated diaphragm (6) to the first valve seat (24b) and second valve seat (25b) is 0.5-1.0 N / mm<2>.

Description

technical field [0001] The present invention relates to a valve device used in various analysis devices such as chemical inspection devices, environmental analysis devices, and bioengineering research equipment. Background technique [0002] In the above-mentioned various analysis devices, the improvement of measurement accuracy, the improvement of inspection speed, the miniaturization of specimens and reagents, and the miniaturization of devices have become important issues. Therefore, valves that control the flow rate of fluid used in measurement Devices require further improvements in performance. In the valve device described above, in order to achieve superior chemical resistance and the like, a diaphragm made of an elastic rubber material or the like is used as the opening and closing mechanism of the valve. The diaphragm constitutes a partition wall that defines the valve chamber, and receives a driving force from the outside to switch the flow path of the fluid. ...
