Description
Technical Field
The utility model belongs to the technical field of hydrogen is stored, especially, relate to a plain type hydrogen storage device.
Background
A hydrogen fuel cell is a power generation unit or device using hydrogen gas as a fuel. In its process of generating electrical energy, gaseous hydrogen is provided. Generally, gaseous hydrogen is stored in hydrogen containers, such as hydrogen cylinders, hydrogen tanks, and the like. When the hydrogen in the hydrogen container is exhausted or cannot be effectively used by the fuel cell, the hydrogen container, such as a hydrogen cylinder, needs to be hydrogenated or filled with hydrogen. However, the pressure (or pressure) of hydrogen gas in a hydrogen storage device, such as a hydrogen storage cylinder or a hydrogen refueling station, for hydrogenating hydrogen gas into a hydrogen gas container such as a small-capacity hydrogen cylinder is high. When hydrogen is filled into the hydrogen cylinder, the hydrogen cylinder and the hydrogen storage cylinder are mostly connected by a connecting mechanism, and then the corresponding control valve is opened and the hydrogen cylinder is filled with the hydrogen, but most of the prior art has no exhaust function.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple hydrogen storage device for overcoming the defects of the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a simple hydrogen storage device comprises a hydrogen storage tank, a first gas pipe detachably arranged on the hydrogen storage tank, a connecting piece used for connecting the first gas pipe with a gas storage tank, a conversion joint arranged on the end part of the first gas pipe, a first three-way joint connected with the conversion joint, a hydrogen pressure gauge arranged on the first three-way joint, a first ball valve arranged on the first three-way joint, a connecting rod matched with a second three-way joint, a second ball valve, a connecting rod, a steering joint arranged on the connecting rod, a second gas pipe connected with the conversion joint, a third gas pipe connected with the second gas pipe, a third ball valve arranged on the third gas pipe and a pressure reducing valve arranged on the third gas pipe; the former hydrogen that passes through the utility model discloses with hydrogen and hydrogen storage tank UNICOM, the hydrogen flow order of the inside generally is: high-pressure hydrogen storage tank → pressure reducing valve → third air pipe → third ball valve → second air pipe → first ball valve → hydrogen pressure gauge → first air pipe → small hydrogen storage tank; before charging hydrogen, the air in the whole device is emptied, and the operation process is as follows: the device is connected, the second ball valve and the third ball valve are opened (the first ball valve is in a closed state), the gas is discharged for three seconds, the first ball valve, the second ball valve and the third ball valve are opened together for two seconds, and then the second ball valve is closed, so that the hydrogen charging can be started.
Preferably, the connecting piece is including locating quick-operation joint female head on the gas holder, locating quick-operation joint male head on the first trachea and locating air flue bayonet socket on the first trachea.
Preferably, a barometer is arranged on the pressure reducing valve.
Preferably, the end of the third air pipe is provided with a pressure reducing valve port.
In summary, to evacuate the air in the whole device before charging hydrogen, the operation process is as follows: the device is connected, the second ball valve and the third ball valve are opened (the first ball valve is in a closed state), the gas is discharged for three seconds, the first ball valve, the second ball valve and the third ball valve are opened together for two seconds, and then the second ball valve is closed, so that the hydrogen charging can be started.
