Air relief valve and the heater that is connected with natural gas (LNG) fuel reservoir, wherein said heater, surge tank and decompression
Valve is sequentially connected with by connecting line；Described casing inner bottom part is provided with heat-insulating shield；Described box body wall is provided with vent.
Preferably, the sealed bottom of described casing, when this device occurs to reveal, sealed bottom can effectively prevent cryogenic liquid
Overflow.
Preferably, described heater uses two water-bath type heat exchangers to be connected in series.
Preferably, described vent is arranged on described box body wall tip position.When this device occurs to reveal, box sealing can
Effectively preventing cryogenic liquid from overflowing, top portion ventilation mouth can make the natural gas gas of gathering quickly spread.
Preferably, in described casing, it is provided with flammable gas detecting alarm device, when detecting road fuel gas content overproof, can
Sending sound and light alarm, automatic emergency cuts off all liquid phase valves simultaneously, it is ensured that this equipment safety operation.
Preferably, described heat-insulating shield is fiberglass heat-insulating shield, can well protect box bottom, has protection ship first simultaneously
The function of plate.
Preferably, in described casing, it is additionally provided with electric control system, uses explosion proof control case to be arranged in casing.
Preferably, one end of described casing is the tank skin of LNG fuel reservoir, described casing and described LNG fuel reservoir shape
Become an entirety, reduce floor space.It is further preferred that described box body wall is welded on the end socket of described LNG fuel reservoir
On, floor space is little, saves installing space.
Preferably, described connecting line arranges relief valve and low-temperature operation valve.
Operation principle of the present utility model is:
Described LNG exits into entrance surge tank after heater is transformed into natural gas through storage tank, after being then passed through air relief valve decompression
It is transported to electromotor by supply air line and provides power for boats and ships.
The beneficial effects of the utility model are:
(1) this utility model makes marine fuel air feed equipment highly integrated, and floor space is little, compact conformation safe and reasonable,
