北京布莱迪BLD YTP隔膜压力表

简介

      隔膜式系列压力表（配接化学密封），是由一个不同类型的通用压力表与一个隔膜隔离体配接而成的。在通用型压力表与隔膜隔离体之间还可以配接具有特定要求的连接体。通过这种配接，使一般通用型的压力表，增加了对特殊腐蚀要求、温度高、粘度大或含有固态浮游物、易凝固介质压力的测量性能。隔膜式压力表（配接化学密封）在石油化工、制碱、化纤、制药、钢铁、食品等行业测量流体介质压力时被广泛使用。

Brief

Series YTP diaphragm pressure gauge (chemical seals) is composed of a conventional pressure measuring instrument, a connector and a diaphragm seal. This combination enables a general purpose pressure gauge to measure media of strong corrosion, high temperature, high viscosity, containing suspended matter or crystallizing. Diaphragm gauges are universally used in petrochemical, alkali, chemical fiber, pharmaceutical,metallurgical, and food industries.

结构原理
       配接化学密封系列压力表的工作原理如图所示。隔离膜片在被测介质压力P的作用下产生变形，压缩内部充填的工作液形成一个相当于 P的压力 P’。经工作液的传导，使压力仪表中的弹性元件自由端产生相应的变形，并按与之相配接的类别压力仪表工作原理显示出被测的压力值。
Configuration Principle
This illustration shows the operating principle of the diaphragm pressure gauge.The diaphragm is deflected by the  pressure of me-dium P, and an equivalent pressure P’ is generated.With transmitting through working fluid, the pressure
P’ deflect the elastic element of a pressure measur-ing instrument which thereafter shows the pressure value.
