定义
The port body is a precision-machined component that serves as the primary structural element in an outlet port assembly with integrated valve. It contains the fluid flow channels, provides mounting surfaces for the valve mechanism, and interfaces with piping systems. Engineered to withstand operational pressures and temperatures while maintaining dimensional stability and leak-tight sealing.
工作原理
Provides a rigid, sealed housing that directs fluid flow through controlled passages. The valve mechanism operates within this body to regulate or shut off flow. Internal geometries are designed to minimize turbulence, pressure drop, and cavitation while maximizing flow efficiency.
材料
Typically ASTM A216 WCB carbon steelASTM A351 CF8M stainless steel (316 equivalent)or ASTM B61 bronze. Material selection depends on fluid compatibilitypressure rating (150-2500 PSI)temperature range (-20°C to 400°C)and corrosion resistance requirements.
Port Size
DN15 to DN300 (1/2" to 12")
Leakage Class
ANSI/FCI 70-2 Class IV or better
Surface Finish
Ra 3.2 μm maximum on sealing surfaces
Connection Type
Flanged, threaded (NPT, BSP), or welded
Pressure Rating
150-2500 PSI
Temperature Range
-20°C to 400°C
标准
ISO 5208ASME B16.34API 600DIN EN 12516

常见问题

What are the main failure modes for port bodies?

Common failures include corrosion erosion at flow surfaces, thermal stress cracking, seal surface degradation, and mechanical deformation under overpressure conditions.

How do I select the right material for a port body?

Consider fluid chemistry (pH, corrosiveness), operating temperature/pressure, required service life, and industry standards. Stainless steel offers best corrosion resistance, carbon steel provides cost-effective strength, and bronze suits marine applications.
