Abstract
The utility model discloses a liquid feeding gun capable of thawing frost on a muzzle of an LNG (Liquefied Natural Gas) liquid feeding gun. The liquid feeding gun comprises a gun body of the liquid feeding gun, wherein the muzzle is arranged at the front end of the gun body of the liquid feeding gun; a heating resistance wire is arranged on the inner wall of the muzzle; the gun body of the liquid feeding gun is provided with an explosion-proof relay box for connecting with an external power supply; the explosion-proof relay box is connected with a circuit of the heating resistance wire; the gun body of the liquid feeding gun is provided with a route control switch and a crank slide block mechanism; the gun body of the liquid feeding gun is pulled out after a liquid is fed; the crank slide block mechanism can move to contact the route control switch; and the route control switch is used for controlling the heating resistance wire to be heated. The heating resistance wire is arranged on the inner wall of the muzzle; the gun body of the liquid feeding gun is pulled out after the liquid is fed, the crank slide block mechanism can move to contact the route control switch and the route control switch is used for controlling the heating resistance wire to be heated, so as to completely remove the frost of the LNG liquid feeding gun and improve the quality of feeding the liquid for the next time.
Description
Technical field
The utility model relates to LNG Liquefied natural gas field, relates in particular to a kind of liquid feeding rifle that can melt LNG liquid feeding rifle muzzle frost.
Background technique
In the situation that the current energy is day by day nervous, reserves are huge, clean, rock gas has become the energy most with prospects after oil and industrial chemicals efficiently.LNG liquid filling station (Liquefied Natural Gas gas station: liquefied natural gas filling station) is the minimum unit of selling the LNG energy for storing.
LNG is filled in needed tank body by liquid feeding rifle.But the liquid feeding rifle that existing LNG liquid filling station uses, after liquid feeding for prevent water vapour sublimate produce frost affect next liquid feeding quality, need to purge with pressurized air the frost of the rifle head generation of cleaning liquid feeding rifle, this has increased the setup time before LNG liquid filling station liquid feeding, thereby increase the operation cost of LNG liquid filling station, and also cannot clean out the frost of generation by pressurized air completely.
Therefore, prior art needs further improvement and develops
Model utility content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of liquid feeding rifle that can melt LNG liquid feeding rifle muzzle frost, realizes LNG liquid feeding rifle is defrosted completely, improves the quality of next liquid feeding.
For solving the problems of the technologies described above, the utility model scheme comprises:
Can melt a liquid feeding rifle for LNG liquid feeding rifle muzzle frost, it comprises liquid feeding rifle rifle body, and described liquid feeding rifle rifle body front end arranges muzzle, on described muzzle inwall, is provided with resistive heater; On described liquid feeding rifle rifle body, be provided with the explosion-proof relay box for connecting external power supply, described explosion-proof relay box is connected with described resistive heater circuit, on described liquid feeding rifle rifle body, travel control switch and slidercrank mechanism are set, complete the extracting of described liquid feeding rifle rifle body liquid feeding, described slidercrank mechanism moves and touches described travel control switch, resistive heater heating described in described travel control switch control.
Described liquid feeding rifle, wherein, is provided with the time relay and tenminal block in described explosion-proof relay box, and the described time relay is connected with described tenminal block one end, and the described tenminal block the other end is connected with described resistive heater.
The utility model provides a kind of liquid feeding rifle that can melt LNG liquid feeding rifle muzzle frost, on muzzle inwall, be provided with resistive heater, complete the extracting of liquid feeding rifle rifle body liquid feeding, slidercrank mechanism moves and touches travel control switch, resistive heater heating described in travel control switch control, realize LNG liquid feeding rifle has been defrosted completely, improve the quality of next liquid feeding, and when reaching explosion-proof relay box after regulation heating time, the power supply that disconnects resistive heater meets economize on electricity needs, has ensured the Security of liquid feeding simultaneously.
Brief description of the drawings
