Rolling Diaphragm​ Introduction:

 

In the design of some medium and low pressure regulators, in order to solve the problem of unbalanced pressure regulator disc and improve the performance of the regulator, the method of installing a balanced diaphragm is often used. Installing a balancing diaphragm increases the differential pressure between the inlet and outlet pressures of the regulator. In the voltage regulator industry, it is called a balanced diaphragm in terms of use, and it is called a rolling diaphragm in rubber, instrumentation, machinery and other industries.

 

The rolling diaphragm is in the shape of a top hat in the free state. It is made of rubber with silk cloth. The top middle hole is used to install the valve stem. In order to install, fix and seal, the top and bottom can have O-ring edges. Or in the form of fixing holes around the bottom edge.

 

 

Rolling Diaphragm​ Characteristics:

 

• Fabrication technics of textile makes the product tear resistance stronger

• High quality raw materials ensure the excellent performance of the material itself
