- the fluid passage is closed by pressing the metal diaphragm 22 against the valve seat 33 from above via the diaphragm presser 27. Further, by pulling up the diaphragm retainer 27 upward, the metal diaphragm 22 is restored to the original shape of the inverted dish, and the fluid passage is opened.
- the metal diaphragm 22 is usually formed from a laminate of 2 to 3 stainless steel thin plates having a thickness of 0.1 to 0.2 mm, and the central portion of the laminate cut out in a circular shape has an inverted dish shape. Formed by bulging and forming!
- the maximum height A h of the bulging portion of the inverted dish-shaped metal diaphragm 22 is about 1.1 to 1.3 mm for the 9.52 mm metal diaphragm (outer diameter: about 26 mm ⁇ ) 22. It is set.
- the valve seat 33 is manufactured by molding an engineering plastic (for example, PFA) into a desired shape, and is fitted into a valve seat holding groove formed integrally with the valve body 21 to hold the holding groove. It is fixed by applying a part of it.
- this type of metal diaphragm valve uses an inverted dish-shaped metal diaphragm 22 as shown in FIG. 10, it is necessary to increase the amount of gas flowing through the fluid passage. Naturally, it is necessary to increase the valve stroke ⁇ S (that is, the amount of deformation of the metal diaphragm 22). For this reason, the maximum bulge height ⁇ ⁇ ⁇ ⁇ ⁇ of the metal diaphragm 22 which is normally bulged and deformed in an inverted dish shape is increased, and a distance substantially equal to the height A h is set as the full stroke AS of the valve.
- the metal diaphragm 22 is always pressed and deformed by a dimension close to the maximum bulge height A h so that it has a substantially flat plate shape. When the valve is opened, it is restored to the original swelled inverted dish shape due to the elastic force and fluid pressure of the catalyst diaphragm 22.
- the maximum flow rate of this kind of metal diaphragm valve is closely related to the valve stroke ⁇ S of the metal diaphragm 22 as described above, and if the valve stroke ⁇ S is increased, the flow rate is selected to be large. I can do it.

- the Cv value required for a metal diaphragm valve is about 0.55 to 0.8.
- the Cv is about 0.7.
- this type of conventional metal diaphragm valve has a problem that it is easy to cause cracks in the metal diaphragm. That is, in general, the durability of this kind of metal diaphragm valve expressed by the number of continuous opening and closing operations is about 1.5 to 2 million times for a 9.52 ⁇ valve with a fluid passage, and about 8 to 10 million times for a 6.35 mm ⁇ valve. When the number of opening and closing operations exceeds the above number, Usually, the metal diaphragm 22 is damaged due to repeated displacement, resulting in an increase in the frequency of conversion of the metal diaphragm valve.
