Description

A kind of LNG Liquefied natural gas liquid-adding device with power gas source gas holder
(1) technical field
The utility model relates to LNG Liquefied natural gas liquid filling station equipment, particularly a kind of LNG Liquefied natural gas liquid-adding device with power gas source gas holder.
(2) background technique
China's LNG Liquefied natural gas (LNG) liquid filling station quantity constantly increases at present, but low temperature pneumatic cut-off valve, liquid filler source purge gas etc. in the power gas source caisson of LNG liquid filling station, the blowing model of LNG vaporizing station before also continuing, directly gives low temperature pneumatic cut-off valve and liquid filler air feed by air compressor.Because the low temperature pneumatic cut-off valve of LNG liquid filling station and liquid filler completely complete and open and purge liquid feeding rifle by power gas source, if also according to former mode air feed, in the time that liquid filler short time gas consumption increases, can cause the low temperature pneumatic cut-off valve in LNG liquid filling station to supply unsaturated vapor, cause low temperature pneumatic cut-off valve to be closed, whole LNG liquid filling station quits work.
(3) model utility content
The purpose of this utility model is for above-mentioned existing problems, and a kind of simple in structure, easy to use, LNG Liquefied natural gas liquid-adding device with power gas source gas holder that source of the gas is stable is provided.
The technical solution of the utility model:
A kind of LNG Liquefied natural gas liquid-adding device with power gas source gas holder, comprise immersed pump pond, immersed pump, LNG Liquefied natural gas liquid filler, power gas source gas holder and electrical control cabinet, immersed pump pond is seal container, immersed pump pond is respectively equipped with liquid inlet pipe low temperature pneumatic cut-off valve and muffler low temperature pneumatic cut-off valve, immersed pump is immersed in immersed pump pond, is in series with respectively outlet low temperature safety check and outlet low temperature pneumatic cut-off valve and enters LNG Liquefied natural gas liquid filler by pipeline on immersed pump fluid pipeline; LNG Liquefied natural gas liquid filler is respectively equipped with liquid-feeding tube and air blowpipe; Power gas source gas holder is respectively equipped with gas holder air inlet ball valve, Blowoff ball valve and four air feed ball valves, import low temperature pneumatic cut-off valve, gas returning port low temperature pneumatic cut-off valve, outlet low temperature pneumatic cut-off valve are connected with four air feed ball valves of power gas source gas holder by pipeline respectively with air blowpipe, and immersed pump is connected with electrical control cabinet respectively by wire with LNG Liquefied natural gas liquid filler.
Working procedure of the present utility model:
The turn on the power air inlet ball valve of source of the gas gas holder and air compression station system connected, then opens four air feed ball valves, makes pneumatic system in running order.LNG enters immersed pump pond by inlet tube low temperature pneumatic cut-off valve, connects after the power supply in electrical control cabinet, opens immersed pump, and liquid feeding system brings into operation.
The utility model has the advantages that: this LNG Liquefied natural gas liquid-adding device by liquid inlet pipe low temperature pneumatic cut-off valve and liquid filler required drive source of the gas by power gas source gas holder concentrated supply, in the time that air blowpipe purges liquid feeding rifle, supply gas pressure does not have larger fluctuation, and supply gas pressure still can held stationary; This apparatus structure is simple, cost is low, safe and reliable to operation.
