Description
Technical field
The present invention relates to a kind of liquefied natural gas filling device, especially relate to a kind of LNG Liquefied natural gas liquid feeding rifle with pressurized gas nozzle.
Background technique
The temperature of LNG Liquefied natural gas under liquid condition is subzero 100 degree.LNG Liquefied natural gas is wanted often to proceed to another container from a container in storage and transportation process, gas consuming device is also equipped with air cylinder usually, LNG Liquefied natural gas, to gas consuming device air cylinder or the filling of other container, is normally injected from container inlet with liquid feeding rifle in container.Although liquid feeding rifle head and container inlet take heat insulation measures, liquid feeding rifle head and container inlet also inevitably cause low temperature when annotating, and will form frost when the water vapour contact liquid feeding rifle head in air and vessel port.The frost gathering of liquid feeding rifle head and container inlet is more will affect filling operation, therefore all will clear up the frost of liquid feeding rifle head and container inlet before each filling and after filling, operates more loaded down with trivial details like this, inefficiency.
The existing defrosting LNG Liquefied natural gas liquid feeding rifle such as patent No. is the Chinese utility model patent of ZL201320780315.3, which disclose a kind of liquid feeding rifle that can melt LNG liquid addition rifle muzzle frost, it comprises liquid feeding rifle rifle body, wherein, described liquid feeding rifle rifle body front end arranges muzzle, and described muzzle inwall is provided with resistive heater; Described liquid feeding rifle rifle body is provided with the explosion-proof relay box for connecting external power supply, described explosion-proof relay box is connected with described resistive heater circuit, described liquid feeding rifle rifle body arranges travel control switch and slidercrank mechanism, described liquid feeding rifle rifle body liquid feeding is complete to be extracted, described slidercrank mechanism moves and touches described travel control switch, and described travel control switch controls the heating of described resistive heater.This patent is declared, muzzle inwall is provided with resistive heater, and liquid feeding rifle rifle body liquid feeding is complete to be extracted, slidercrank mechanism moves and touches travel control switch, travel control switch controls the heating of described resistive heater, achieves and defrosts completely to LNG liquid addition rifle, improve the quality of next liquid feeding.This liquid feeding rifle that can melt LNG liquid addition rifle muzzle frost adopts resistive heater heating power to melt liquid feeding rifle head and container inlet frost, because rock gas is flammable explosive gas, electric heating wire is set in liquid feeding rifle muzzle, melts frost with electric heating wire electrified regulation dangerous.
Summary of the invention
In order to solve in prior art, liquid feeding rifle head and container inlet easily condense frost, clear up loaded down with trivial details, resistive heater heating power is adopted to melt liquid feeding rifle head and container inlet frost unsafe problem again, the invention provides another antifrost LNG Liquefied natural gas liquid feeding rifle, this antifrost LNG Liquefied natural gas liquid feeding rifle adopts the method for pressurized gas nozzle ejection pressurized gas, removes the frost of liquid feeding rifle head and the condensation of container inlet, safe and reliable, cleaning effect is good.
The technological scheme that technical solution problem of the present invention adopts is: a kind of antifrost LNG Liquefied natural gas liquid feeding rifle, comprise ascending pipe, sleeve and the collar, described sleeve bottom arranges receiver, described sleeve is fixed on described receiver, there is circular hole at described receiver center, described ascending pipe is through the circular hole at described receiver center, and described ascending pipe can only move forward and backward and can not surrounding rock in described sleeve and described receiver; Injection base is set bottom described ascending pipe, described ascending pipe is fixed on described injection base, described ascending pipe connects gas source pipe, the described collar is set on described sleeve, it is characterized in that: described barrel forward end barrel offers multiple hole, moveable mounting jaw hook in hole, the described collar is on described sleeve during forward slip, and the described collar extrudes described claw hook front end makes multiple described claw hook inwardly grab conjunction simultaneously; When the described collar slides backward on described sleeve, the described collar extrudes described claw hook rear end makes multiple described claw hook outwards open simultaneously; Described receiver both sides hinged handle, difference articulated linkage on two described handles, the other end of two described connecting rods is hinged on described injection base both sides respectively; Described injection base is connected with push rod with between the described collar, between described receiver and described injection base, arrange spring.
Wherein, described sleeve is a cheese, and nozzle internal diameter is slightly larger than gas consuming device air cylinder bottleneck external diameter, and during liquid feeding, described jacket casing is on bottleneck; Described ascending pipe is arranged in described sleeve, the described collar is arranged on outside described sleeve, the relatively described collar of described sleeve and described ascending pipe are static, the described collar is connected with injection base by push rod with described ascending pipe, and the described collar and described ascending pipe can move forward and backward on described sleeve.During liquid feeding first by described jacket casing on gas consuming device air cylinder bottleneck, the described claw hook of described collar reach extruding is driven again by promoting described handle, multiple described claw hook closes promptly bottleneck snap ring simultaneously, and the described ascending pipe one-way valve backed down in bottleneck that protracts injects LNG Liquefied natural gas in bottle simultaneously.
As the technological scheme improved further, arrange nozzle in described barrel forward end barrel, described nozzle is connected with high-pressure air pipe.
As the technological scheme improved further, arrange stroke valve between described nozzle and described high-pressure air pipe, one end of described stroke valve is fixed on described receiver, and the other end of described stroke valve is fixed on described injection base.
As the technological scheme improved further, described stroke valve comprises tracheae, lower tracheae, piston sleeve and piston rod, described upper tracheae is communicated with the cavity volume of described piston sleeve, described lower tracheae is communicated with the lower gas port in described piston rod, upper gas port in described piston rod is communicated with the cavity volume of described piston sleeve, in the middle part of described piston sleeve, inwall arranges air drain, when described piston rod moves in described piston sleeve, when described upper gas port and described lower gas port arrive described air drain place simultaneously, described upper gas port can be communicated with described lower gas port.
As the technological scheme improved further, described connecting rod arranges restraining groove, described receiver arranges limited post, when described handle upwardly time, described restraining groove is stuck on described limited post and plays position-limiting action.
The invention has the beneficial effects as follows: due to a kind of antifrost LNG Liquefied natural gas liquid feeding rifle of the present invention, at sleeve upper mounting jaw hook, during liquid feeding, claw hook is made to hook bottleneck snap ring with jacket casing both hands driven forward handle on air cylinder bottleneck, simultaneously the ascending pipe one-way valve backed down in bottleneck that protracts injects LNG Liquefied natural gas in air cylinder, after injection, both hands are pulled back handle, and while bottleneck thrown off by claw hook, stroke valve is opened, and nozzle ejection pressurized gas remove the frost of bottleneck and muzzle.This antifrost LNG Liquefied natural gas liquid feeding rifle is easy to operate, and frost elimination effect is good, use safety.
