Introduction:
Pneumatic valve adjustment diaphragms are simply referred to as "pneumatic valve diaphragms." Pneumatic valve diaphragms are usually butterfly-shaped, with their sidewalls gradually drawn from the cylinder to the piston. It can be designed as a double layer to withstand pressure in both directions. Due to its wide convolution and tapered side walls, its ability to withstand high pressures is limited. The effective pressure will also change during the mid-range process.

Both the piston and flange of the pneumatic valve diaphragm are molded in the same place. The advantage of this type of diaphragm is that there is no need to manually swivel, which greatly reduces assembly time. This is especially important in high volume applications. The downside of this model is that due to the cast-in swing, the redesign must take into account the built-in elastic stiffness, as well as the stroke limit ratio. To increase this ratio, a pre-convolution diaphragm can be designed for offset. In this shape, the piston crown and flange are cast to counteract each other, transferring the extra stroke capacity to one side of the swing. This allows the diaphragm to have a longer stroke capability while maintaining ease of assembly.
The diaphragm of the pneumatic control valve is a key component of the pneumatic control valve. Recently, many netizens have responded that the reason for the damage to the diaphragm of the pneumatic control valve is unknown. Here is an introduction:
The main reasons for the rupture of the diaphragm of the pneumatic control valve are:
