选阀门不同的方面来选择

金彩汇Choose valves from different aspects

阀门的功能：根据阀门是用于切断还是调节流体的流量和压力来选择，如需快速启闭则应考虑闸阀、截止阀、球阀、蝶阀等通用阀门，调节流量的可选择电动或气动调节阀，调节压力的选择减压阀。

金彩汇The function of the valve: It is selected based on whether the valve is used to cut off or regulate the flow and pressure of the fluid. If quick opening and closing is required, universal valves such as gate valves, globe valves, ball valves, butterfly valves, etc. should be considered. Electric or pneumatic regulating valves can be selected for regulating flow, and pressure reducing valves can be selected for regulating pressure.

阀门的尺寸：根据流体的流量和允许的压力损失来决定阀门的尺寸，一般应与工艺管道的尺寸一致。

金彩汇Valve size: The size of the valve is determined based on the fluid flow rate and allowable pressure loss, and should generally be consistent with the size of the process pipeline.

金彩汇流体的温度和压力：根据阀门的工作温度和压力来确定阀门的材质和压力等级。介质的腐蚀性。根据介质的腐蚀性确定阀门材料。

Temperature and pressure of fluid: Determine the material and pressure rating of the valve based on its operating temperature and pressure. The corrosiveness of the medium. Determine valve materials based on the corrosiveness of the medium.

金彩汇介质的流速流量：根据介质的流速流量确定阀门公称直径。安装操作。根据安装操作、管理经济性确定阀门结构形式。

金彩汇Flow rate of medium: Determine the nominal diameter of the valve based on the flow rate of the medium. Installation operation. Determine the valve structure form based on installation operation and management economy.

阀门材料：选择阀门的主要零件的材质，首先应考虑到工作介质的物理性能（温度、压力）和化学性能（腐蚀性）等。

金彩汇Valve material: When selecting the material of the main components of the valve, the physical properties (temperature, pressure) and chemical properties (corrosiveness) of the working medium should be considered first.

金彩汇阀门验收：检查外观质量和几何尺寸，查看阀门产品合格证和质量证明书，检查阀门开启关闭是否灵活。

Valve acceptance: Check the appearance quality and geometric dimensions, inspect the valve product certificate and quality certificate, and check whether the valve opens and closes flexibly.
