阀塞体

Precision-machined plug body for industrial valve systems controlling fluid flow.

技术定义与适配语境
典型 阀塞体 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The plug body is a critical component in plug valves, serving as the rotating element that regulates fluid flow through the valve. It features a tapered or cylindrical design with a through-port that aligns with the valve body ports to allow flow or rotates to block it. Engineered for precise fit within the valve body, it ensures leak-tight sealing and smooth operation under various pressure and temperature conditions.

定义
The plug body is a critical component in plug valves, serving as the rotating element that regulates fluid flow through the valve. It features a tapered or cylindrical design with a through-port that aligns with the valve body ports to allow flow or rotates to block it. Engineered for precise fit within the valve body, it ensures leak-tight sealing and smooth operation under various pressure and temperature conditions.
工作原理
Operates by rotating 90 degrees within the valve body to open or close the flow path. The plug's port aligns with the inlet and outlet ports in the open position, allowing fluid passage. In the closed position, the solid section of the plug blocks the ports, stopping flow. Sealing is achieved through mechanical interference, lubricants, or elastomeric sleeves.
