The projection (as shown in Figure 4) of technique formation is pressed, when being connected by tightening bolt formation flange, other areas of pressure ratio at pressure ripple
The pressure in domain is big, so as to form the band of closing around pad flow passage openings to realize the effect of Fluid Sealing；Due to
In the case of pressure wave height identical, corrugating into circular arc radius (press ripple radius) it is bigger, press the shape of ripple gentler,
Correspondingly pressure ripple rigidity of the pad in the position is smaller, therefore can form relatively small pressure when being compacted, therefore, in stress
Form the larger pressure ripple of pressure ripple radius around larger pad flow passage openings D, and the less pad flow passage openings A of stress,
The pressure less pressure ripple of ripple radius is formed around B, C, and the height of all pressure ripples is identical.For example, can be in pressure wave height phase
The pressure ripple radius in pad flow passage openings D regions is arranged to the pressure in about pad flow passage openings A, B, C regions with the premise of
Twice of ripple radius is to reach favourable sealing effectiveness.By this way, when forming flange connection, each fluid passage mouth region domain
Pressure distribution it is more uniform so that avoid due to respective regions pressure it is excessive caused by flange facial disfigurement and subregion pressure
The fluid seepage that power deficiency is caused.
In addition, in an exemplary embodiment of the present invention, due to screwed hole 5 and remaining screwed hole and fluid passage
Mouthful it is distant, therefore in order to when forming flange connection pad will not occur bending and deformation and cause discontinuity, can be with
Set and pad flow passage openings A, B, C, D around pad connecting hole E in the position corresponding to screwed hole 5, i.e. shown in Fig. 3
