Liquid Surge Relief Valveisa safe pressure release device, which specialty design to fluid gathering transportation pipeline. It aims to rapidly measuring pipeline pressure change, response according the measuring, protect oil transportation pipeline safety, and protect the pipeline system and equipment from damage by the pipeline abnormal pressure surge, which occurs by transient flow. These protection forms by surge relief valve itself, it is an automatic valve.
This Liquid Surge Relief Valve arewidely used in medium gathering transportation pipeline system, such as: pipeline system transport crude oil, refined oil, chemical product, water, etc. It is performas a pipeline safety protection device, it is a preferred solution to high velocity and silt crude oil pipeline. it is installed at the inlet or outlet of pump station as the low/high pressure protection valve, to protect the station equipment or the outlet pipe.
1. Automatic Pressure Relief: When the pipeline pressure over set-point, theliquid surge relief valvewould quickly response to relief the overpressure
2. Automatic Close: When the pipeline pressure relief to a set-point, the liquid surge relief valvewould back to seat automatic, no medium waste
3.Pressure Signal Automatic Measure And Alarm Function: When the nitrogen supply pressure lower to the capability of stable supply nitrogen pressure, or the nitrogen pressure higher or lower to set-point, the sensor would transfer the measured signal to station control system to alarming.
4. Temperature Stable Function: buried nitrogen tank, ensure the pressure stable no matter in winter or summer, restrain the affect on the nitrogen set pressure caused by atmosphere temperature changes.
