Background
The diaphragm valve is a stop valve which uses a diaphragm as an opening and closing piece to close a flow passage, cut off fluid and separate an inner cavity of a valve body from an inner cavity of a valve cover. The diaphragm is made of elastic, corrosion-resistant and impermeable materials such as rubber and plastics. The valve body is made of multipurpose plastic, glass fiber reinforced plastic, ceramic or metal lining rubber material. Simple structure, better sealing and corrosion resistance and small fluid resistance. The medium is used for low pressure, low temperature, medium with strong corrosiveness and suspended substance. The structure is divided into a ridge type, a stop type, a gate type and the like. The driving modes are manual, pneumatic and electric.
