原文:
I. Selection In building pipeline systems, valves control the fluid plays a role. Because of the different structures and materials, so to create the valve also varies. In order to ensure the pipeline system to achieve the highest efficiency, lowest cost and longest life, the correct valve selection is essential. Second, functional Valve has four main functions: 1. To start and stop media flow 2. Adjustment (throttle) media flow 3. To prevent backflow or back 4. Adjustable or discharge fluid pressure Three, a major factor in pipeline system 1. Pressure 2. Temperature 3. Fluid Media Types a) Fluid b) gas: for example, steam or air c) impurities, or Varnish (corrosive substances) content d) Corrosive 4. Medium Flow a) Open - Close-conditioning b) the need to prevent backflow or back c) concern about pressure drop d) flow rate 5. The work environment a) condensation b) operating frequency c) accessibility d) Dimension / applicable to the space e) manual or automatic control f) needs to have close performance, non-bubble
