一般安装信息
General Installation Information
仪表保护装置和仪表在隔膜的仪表一侧上,必须完全填满适当的液体,例如甘油或蒸馏水,以便精确传递系统压力或真空。按照随货包装的说明书要求正确进行填充和安装。工厂安装仪表和仪表保护装置组合是预先填充的。(请联系美国斯毕尔公司技术服务部了解进一步的信息)。PTFE材质隔膜通常具有广泛的耐化学品腐蚀能力,Viton®材质或EPDM材质弹性隔膜则具有更好的灵敏性,应该用于低压(即,0~15
psi)和真空应用场合。
The Gauge Guard and gauge must be completely filled
with a suitable liquid, such as glycerin or distilled water, on the gauge
side of the diaphragm in order to accurately transmit system pressure
or vacuum. Follow packaged instructions for proper filling and installation.
Factory installed Gauge & Gauge Guard units are pre-filled. (Contact
Spears® Technical Service for additional information). While PTFE
diaphragms generally have a broader range of chemical resistance, Viton®
or EPDM elastomer diaphragms are more sensitive and should be used in
low pressure (i.e., 0-15 psi) and vacuum applications. |

特点 - PVC, CPVC和聚丙烯
Features - PVC, CPVC & PP
仪表保护装置通过采用一个细薄的PTFE(标准配置)、Viton®或EPDM隔膜将工艺压力仪表或真空仪表与腐蚀环境或其他可能造成损害的处理流体介质隔离开来。与仪表正确组装并充满液体后,这种柔软的隔膜精确地传递系统压力到仪表连接腔。可提供的结构材料有PVC,
CPVC或聚丙烯,连接端口有DN15 x DN8或DN8 x DN8进口 x 出口美国标准锥管螺纹NPT连接。
Gauge Guards isolate process pressure or vacuum
gauges from corrosive or other potentially damaging process media by use
of a thin PTFE (standard), Viton®, or EPDM diaphragm. This flexible
membrane accurately transmits system pressure to gauge connection chamber
when properly assembled with gauge and liquid filled. Available in PVC,
CPVC or Polypropylene construction with 1/2"
x 1/4" or 1/4" x
1/4" inlet x outlet NPT connections.
