Globe Valve:
- 因舊嘢個樣成個波咁而得名。可用嚟調較水量,同埋由於裡面成隻碟向下座,更低leakage; 但重,Pressure Drop大,
Check Valve:
- 阻止水倒流,同二極管原理類似;上面有個鏍絲開蓋換裡面塊Disc
Pressure Guage:
- 顧名思義,攞嚟度Pressure. 原理係少量水隊上去頂住裡面隻碟再調個指針
Y-Strainer
- 啲水流過隔垃圾
Gate Valve
- 因個閘成個Gate咁款而得名。只能用嚟做開關,難以較水量。好處係平、簡單設計、Low pressure drop;但如果關唔實會有Vibration, 同埋由於塊disc插入方向,冇Globe Valve關得咁實。
Gate Valve (駁住Pressure Guage嗰個),又叫Plug Valve, 同Ball Valve好似,外形上唔易分
- 細件,可經常開關,Low Pressure Drop. 呢類轉九十度開關既Valve相對反應快;用於相對細flow
仲有啲係上面張圖冇但係又經常用既Valve:
Butterfly Valve
- 反應快,Low Pressure Drop, 用响High flow low pressure,
Pressure Reducing Valve
- 顧名思義,降壓用
