Description
Technical field
The utility model belongs to liquefied natural gas filling equipment technical field, specifically a kind of Simple bottle group filled by pump
Filling apparatus.
Background technology
Liquefied natural gas (LNG) is because its storage and transportation is convenient, the characteristics such as safe and clean, in industrial, civilian and some special industries
It is widely used.And LNG bottles of groups are small suitable for gas consumption, as small-sized deposit compressed air source unit, steel cylinder fills always
Comparatively laborious problem, while in view of steel cylinder uses the actual conditions of process, majority does not have cylinder filling platform, not to vapour yet
The corollary apparatus of vehicle liquid feeding, but it is desirable to the tank bottle pump sleds in LNG gasification station to solve the problems, such as filling for steel cylinder.
Invention content
The purpose of this utility model is in view of the deficiencies of the prior art, and to propose that a kind of Simple bottle group filled by pump is filling
Device.
The utility model solves its technical problem and following technical scheme is taken to realize：
A kind of Simple bottle group filling apparatus filled by pump, include with prize outer source of supply pump pull out inlet that mouth is connect and
The gas returning port being connect with the outer BOG recovery systems of sled, inlet are connect by liquid flowing valve with feed liquor main line, and gas returning port is by returning
Air valve is connect with return-air main line, and the charging line that multichannel carries low temperature check-valves is mounted in parallel on feed liquor main line,
It is connect with the liquid phase mouth of LNG steel cylinders after the liquid phase valve and metal hose that pass through concatenation per road charging line, in return-air main line
On be mounted in parallel the return line that multichannel carries gas phase valve, the gas for passing through metal hose and LNG steel cylinders per road return line
Phase mouth connect, meanwhile, be connected between the inlet ductwork and return-air main line of each liquid phase valve with gas-liquid bridge valve across
Take over road, moreover, being mounted on low-temperature safety valve on feed liquor main line and return-air main line.
Moreover, being mounted on pressure gauge on feed liquor main line and return-air main line.
The advantages of the utility model and good effect are：
1, utility model device is quick, convenient, easily operated, easy to maintenance, safe and reliable, flow setting is simple, throws
It provides at low cost, and can prevent medium from flowing backwards.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model implementation is further described below in conjunction with attached drawing, following embodiment is descriptive, is not
Limited, protection scope of this utility model cannot be limited by this.
A kind of Simple bottle group filling apparatus filled by pump, as shown in Figure 1, including pulling out mouth with the outer source of supply pump of sled to connect
Inlet 10 and with the gas returning port 11 prizing outer BOG recovery systems and connect, inlet passes through liquid flowing valve 9 and feed liquor main line company
It connects, gas returning port is connect by return air valve 12 with return-air main line, has been mounted in parallel on feed liquor main line multiple with low temperature
The charging line of check-valves 6, the liquid after liquid phase valve 1 and metal hose 3 that each charging line passes through concatenation with LNG steel cylinders 2
Phase mouth connects, and multiple return lines with gas phase valve 4 is mounted in parallel on return-air main line, each return line passes through
Metal hose is connect with the gas phase mouth of LNG steel cylinders, moreover, being managed between the inlet ductwork and return-air main line of each liquid phase valve
Road is connected with gas-liquid bridging valve 5.
In the specific implementation of the utility model, in order to ensure the safe operation of bus-bar, in feed liquor main line and return-air
Low-temperature safety valve 8 is mounted on main line.
In the specific implementation of the utility model, in order to constantly monitor the operating status of bus-bar, in feed liquor main line and
Pressure gauge 7 is mounted on return-air main line.
Operation principle
The device be by LNG steel cylinders gas phase mouth and liquid phase mouth by gas phase at flange-connection stainless steel metal flexible pipe and bus-bar and
Liquid phase valve is connected, and inlet pulls out mouth with the outer source of supply pump of sled and connect, and gas returning port is connect with outer BOG recovery systems are prized, low temperature
Safety valve bottom valve is opened, and in filling process, gas-liquid bridges valve and closes, remaining valve opening.Liquefied natural gas passes through inlet,
By main line liquid flowing valve and to pass sequentially through concatenated low temperature check-valves, bus-bar bottle group liquid phase valve, stainless steel metal soft
Pipe reaches LNG Dewar bottle body liquid feed valves and enters interior of steel bottle.The BOG gases generated in steel cylinder in filling process, pass sequentially through
LNG Dewar bottle bodies drain valve, flange-connection stainless steel metal flexible pipe, bus-bar bottle group gas phase valve by main line return air valve and return
Gas port enters recovery system.Steel cylinder opens gas-liquid bridging by after weighing and ensuring to be full of, closing steel cylinder ontology feed liquor and drain valve
Valve will be discharged into the outer BOG systems of sled after residual LNG gasification in header by return-air duct, and filling process terminates, here, low temperature
Check-valves effectively prevent liquid in filling process to flow backwards.
