  閥門的分類

  Classification of valves

  按動力分

  Divided by power

  自動閥:依靠介質自身力量進行動作的閥門。如止回閥、減壓閥、疏水閥、安全閥等。

  Automatic valve: a valve that operates based on the force of the medium itself. Such as check valves, pressure reducing valves, drain valves, safety valves, etc.

  驅動閥:依靠人力、電力、液力、氣力等外力進行操縱的閥門。如截止閥、節流閥、閘閥、碟閥、球閥、旋塞閥等。

  Drive valve: a valve that relies on external forces such as human, electric, hydraulic, and pneumatic to operate. Such as globe valves, throttle valves, gate valves, disc valves, ball valves, plug valves, etc.

  按結構特性分

  按用途分

  Classified by purpose

  開斷閥:切斷或接通管路介質。如截至閥、閘閥、球閥、旋塞閥等;

  Cut off valve: Cut off or connect the medium in the pipeline. Such as globe valves, gate valves, ball valves, plug valves, etc;

  調節閥:調節介質的壓力或流量。如減壓閥、調節閥;

  Regulating valve: regulating the pressure or flow rate of the medium. Such as pressure reducing valves and regulating valves;

  止回閥:防止介質倒流。如止回閥。

  Check valve: prevents medium backflow. Like a check valve.

  分配閥:改變介質的流向,起分配作用。如三通旋塞、三通截止閥等。

  Distribution valve: changes the flow direction of the medium and plays a distribution role. Such as three-way plug valves, three-way globe valves, etc.

  安全閥:壓力超限定數值時,排放多余的介質,保證設備安全。如安全閥、事故閥;

  Safety valve: When the pressure exceeds the limit value, excess medium is discharged to ensure equipment safety. Such as safety valves and accident valves;

  阻氣排水閥:留存氣體、排除凝結水,如疏水閥。

  Gas blocking drain valve: retains gas and eliminates condensed water, such as a drain valve.

  Gas blocking drain valve: retains gas and eliminates condensed water, such as a drain valve.

  按操縱方法分

  Classified by manipulation method

  手動閥門:借助手輪、手柄、杠桿、鏈輪、齒輪、蝸輪等,由人力來操縱的閥門。

  Manual valve: a valve that is manually operated using a handwheel, handle, lever, sprocket, gear, worm gear, etc.

  電動閥門:借助電力來操縱的閥門。

  Electric valve: a valve operated by electricity.

  氣動閥門:借助壓縮空氣來操縱的閥門。

  Pneumatic valve: a valve operated by compressed air.

  液動閥門:借助水、油等液體,傳遞外力來操縱的閥門。

  Hydraulic valve: a valve operated by transmitting external force through liquids such as water and oil.

  按壓力分

  Divided by pressure

  真空:絕對壓力小于1公斤/厘米2的閥門。

  Vacuum: Valve with an absolute pressure less than 1 kg/cm2.

  低壓:公稱壓力小于16公斤/厘米2的閥門。

  Low pressure: valves with a nominal pressure less than 16 kg/cm2.

  中壓:公稱壓力25-64公斤/厘米2的閥門。

  Medium pressure: valves with a nominal pressure of 25-64 kg/cm2.

  高壓:公稱壓力100-800公斤/厘米2的閥門。

  High pressure: valves with a nominal pressure of 100-800 kg/cm2.

  超高:公稱壓力達到或大于1000公斤/厘米2的閥門。

  Ultra high: Valves with a nominal pressure of 1000 kg/cm2 or greater.

  按介質溫度分

  Divided by medium temperature

  普通閥門:-40至450℃(介質溫度)}的閥門。

  Ordinary valves: valves ranging from -40 to 450 ℃ (medium temperature).

  高溫閥門:450至600℃(介質溫度)的閥門。

  High temperature valve: a valve with a temperature range of 450 to 600 ℃ (medium temperature).

  耐熱閥門:600℃以上(介質溫度)的閥門。

  Heat resistant valve: a valve with a medium temperature above 600 ℃.

  低溫閥門:-40至-70℃(介質溫度)的閥門。

  Low temperature valve: a valve with a temperature range of -40 to -70 ℃ (medium temperature).

  深冷閥門:-70至-196℃(介質溫度)的閥門。

  Cryogenic valve: a valve with a temperature range of -70 to -196 ℃ (medium temperature).

  超低溫閥門:-196℃以下(介質溫度)的閥門。

  Ultra low temperature valve: a valve with a medium temperature below -196 ℃.

  按公稱通徑分

  Divided by nominal diameter

  小口徑:公稱通徑小于40毫米的閥門。

  Small caliber: valves with a nominal diameter less than 40 millimeters.

  中口徑:公稱通徑50至300毫米的閥門。

  Medium caliber: valves with a nominal diameter of 50 to 300 millimeters.

  大口徑:公稱通徑350至1200毫米的閥門。

  Large caliber: valves with nominal diameters ranging from 350 to 1200 millimeters.

  特大口徑:公稱通徑大于1400毫米的閥門。

  Extra large caliber: valves with a nominal diameter greater than 1400 millimeters.

  以上分類并不是絕對的,可以從其他角度分類,只需掌握了這些基本分類,對了解品類繁多的閥門還是有很大好處的。

  The above categories are not absolute and can be classified from other perspectives. As long as you master these basic categories, it is still very beneficial for understanding the wide variety of valve categories.
