Magnetic valve diaphragm is a circular membrane-shaped elastic sensitive element. When the two sides of the diaphragm are acted upon by different pressures (or forces), the diaphragm will strain and move to the side with lower pressure, causing its center to produce a displacement that is related to the pressure difference.
When the two sides of the circular membrane-shaped elastic sensitive element diaphragm are acted upon by different pressures (or forces), the diaphragm will strain and move to the side with lower pressure, causing its center to produce a displacement that is related to the pressure difference. There are three main types of diaphragms: flat diaphragm, vertical chain diaphragm and corrugated diaphragm. Diaphragms can also be divided into various forms according to whether the periphery is fixedly supported, whether the center is open, and the stress distribution in the diaphragm area. , the most commonly used one is a flat diaphragm composed of circular thin plates of equal cross-section fixed at the periphery. The chain diaphragm is composed of a circular plate with a groove near the edge. Its elastic strain mainly occurs at the edge annular groove. This kind of diaphragm is commonly used. The hard center part of the chain diaphragm is close to translation when it is moved under pressure, so it is more effective for capacitive sensors or piezoelectric sensors. The corrugated diaphragm is pressed with annular concentric ripples. In order to increase the displacement of the diaphragm center, two diaphragms can be welded together to form a diaphragm box or several diaphragms can be further connected in series to form a diaphragm box group
