   孔板10bet对于介质的要求?西安华恒仪表介绍:孔板10bet又称为差压式10bet,是由一次检测件(节流件)和二次装置(差压官网和流量显示仪)组成,广泛应用于气体、蒸汽和液体的流量测量。

 
  The requirements of orifice flowmeter for medium?Xi'an Huaheng Instrument Introduction:Orifice plate flowmeter,also known as differential pressure flowmeter,is composed of primary detection parts(throttle parts)and secondary devices(differential pressure transmitter and flow indicator),which is widely used in gas,steam and liquid flow measurement.
 
  标准孔板可以采用角接取压(包括环室取压和钻孔取压)、法兰取压或D-D/2取压三种取压方式。
 
  Standard orifice plate can adopt angular connection pressure(including ring chamber pressure and borehole pressure),flange pressure or D-D/2 pressure.
 
  测量口径DN50-DN1200,压力0-16MPa,温度0-550℃。
 
  Measuring diameter DN50-DN1200,pressure 0-16MPa,temperature 0-550 C.
 
  介质:煤气、天然气(包括含湿度5%以下)、各种碳氢化合物(包括含湿的HC气体)、各种稀有气体(氢、氦、氩、氧、氮等)、氯气、湿的氯化物气体、空气(包括含水、含SiO2粒子以及含其他悬浮物的空气)、烟道气、饱和蒸汽(含汽、水两相流)、过热蒸汽、水等。几乎涵盖了所有流动性介质。
 
  Medium:gas,natural gas(including humidity below 5%),hydrocarbons(including wet HC gas),rare gases(hydrogen,helium,argon,oxygen,nitrogen,etc.),chlorine,wet chloride gas,air(including water,SiO 2 particles and air containing other suspended matter),flue gas,saturated steam(steam,water two-phase flow),superheated steam,water,etc.Almost all liquidity media are covered.
 
  孔板10bet按国标规定进行设计、制造和检定的标准孔板无需实流标定,精度高、结构简单、制造成本低,但压力损失在所有标准节流装置中最大,不适用于要求压力损失小的情况,标准孔板广泛用于石油、化工、冶金、电力等行业。
 
  The orifice plate flowmeter designed,manufactured and calibrated according to the national standard does not need real-flow calibration.It has high accuracy,simple structure and low manufacturing cost.However,the pressure loss is the largest in all standard throttling devices,and it is not suitable for situations requiring low pressure loss.The standard orifice plate is widely used in petroleum,chemical,metallurgical,power and other industries.
