Introduction:
In the design of some medium and low pressure regulators, in order to solve the problem of unbalanced pressure regulating valve disc and improve the performance of the pressure regulator, the method of installing a balance diaphragm is often used. When a balancing diaphragm is installed, the differential pressure between the inlet pressure and the outlet pressure of the regulator can be increased. In the regulator industry, it is called a balance diaphragm in terms of use, and it is called a rolling diaphragm in the rubber, instrument, 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.
Materials details:
For the present, common materials for rolling diaphragm are: natural rubber (NR), nitrile butadiene rubber (NBR), the performance of the two materials can meet the needs of most industrial environments. In special industrial environments (high temperature resistance, acid and alkali resistance) could use EPDM, fluorine rubber (FKM), neoprene rubber (CR) for production, but the cost is relatively high.
