Check valve installed on the liquid-phase pipeline of LNG vehicle refueling stations
Thread Content
During the LNG certification inspection, the inspector in charge of special containers is willing to install check valves on the pipes for unloading liquid from the vehicles and on the outlet pipes of the multi-stage pumps; however, the original manufacturer’s design does not include such valves. Do people think it is necessary?
When necessary, the unloading pipelines and pump outlets are required by the standards. vx150-6330-8877
A low-temperature vehicle is necessary; an emergency shut-off valve or a one-way check valve should be installed on the pipeline coming out of the tank, near the housing.
