The bellows gate valve is composed of the following parts:
OneRam:
The ram is the key component of the bellows gate valve, which is connected by the telescopic mechanism and the bellows to play the role of opening and closing the pipeline.
IIBellows:
The bellows is the power part of the bellows gate valve, which pushes the opening and closing of the ram through telescopic deformation.
IIIBody:
The valve body is the main part of the bellows gate valve, including the connecting part of the inlet and outlet and the bellows. The valve body is usually made of materials such as cast iron, steel plate, stainless steel, etc.
FourthSealing structure:
The sealing structure of the bellows gate valve includes the seal between the ram plate and the valve body and the seal between the bellows and the pipeline. Among them, the ram seal is usually a soft seal or metal seal, and the bellows seal is made of rubber or PTFE and other materials.
FiveOperating Mechanism:
The operating mechanism of bellows gate valve mainly includes manual operation, electric operation and pneumatic operation, which can be selected according to specific use scenarios.
In general, the bellows gate valve is a type of valve with simple structure, high reliability and low maintenance cost, especially suitable for pipelines with high temperature, high pressure and corrosive media.
