Embodiment 1
[0033] Such as Figure 1 to Figure 5 as well as Figure 10 to Figure 11As shown, a method for making a fine orifice plate, the method includes the following steps: pressing a straight stainless steel strip with a length of 100m, a thickness of 0.25mm, and a width of 10mm to form a wave pitch P=1mm and a wave height H=0.8mm . A corrugated strip 2 with a sinusoidal curved surface, the corrugated strip 2 has a length L'=82m, a thickness S=0.25mm, and a width B=10mm. Match the corrugated belt 2 with a straight belt 3 made of stainless steel with a length L=87m, a thickness M=0.25mm, and a width B =10mm. Align to form a wave flat belt 1 with one side being a flat surface (i.e. C surface) and the other side being a wave surface (i.e. D surface), and then the wave flat belt 1 starting end (i.e. end a) is fixed on the central axis 4. The central shaft 4 is a hollow tube shaft whose cross section is a ring-shaped plastic material with an inner diameter of 100 mm and an outer diameter...
Embodiment 2
[0035] Such as figure 1 , Figure 10 to Figure 13 Shown, a kind of method for making fine orifice plate, described method comprises the steps: take one side of length L=150m to be flat surface (being C surface) the other side has wave surface (being D surface) The wave flat belt 1 of stainless steel material, the wave surface shape of the wave flat belt 1 is a sinusoidal wave belt 2, the thickness M' of the wave flat belt 1 from the flat surface (ie C surface) to the wave valley point (ie point d) =1.5mm, M' is the vertical distance from the flat surface (C face) in the wave flat band 1 to the valley point (d point) of the wave surface, the width B of the wave flat band 1"=5mm, the wave surface of the wave flat band 1 The wave distance P=1.5mm, wave height H=1.5mm.The initial end (being a end) of this wave flat band is fixed on the central axis.The section of the plastic material that central axis 4 is inner diameter 100mm, outer diameter 120mm is annulus Shaped hollow tube ...
Embodiment 3
[0037] Such as Figure 1 to Figure 6 as well as Figure 10 to Figure 11 As shown, a method for making a micro-orifice plate, its steps are basically the same as in Embodiment 1, the difference is that the wave surface shape of the wave band 2 is arc-shaped, that is, the wave surface shape of the wave flat band 1 is arc-shape. The central axis 4 is a solid axis with a circular cross section. The end end (ie b" end) of the flat strip 3 is bonded. The material of the flat strip 1 is copper.
