The 70MPa hydrogen nozzle is provided with an automatic locking structure. After the nozzle head and the hydrogen port are connected in place, the internal jaws of the hydrogen nozzle automatically clamp the hydrogen port and lock it, which makes the hydr Technical Specifications ogen nozzle and the hydrogen port form a reliable mechanical connection. After the hydrogen nozzle successfully communicates with the vehicle-mounted system, press the hydrogen filling button on the hydrogen dispenser, and the high-pressure hydrogen flows to the vehicle-mounted steel cylinder at the back end of the hydrogen port through the hydrogen nozzle to fill hydrogen for the vehicle. After filling, the hydrogen nozzle will release the pressure of the gas inside the chamber of the hydrogen nozzle autonomously. After the pressure relief is completed, manually slide the outer sliding sleeve on the head of the hydrogen nozzle to separate the hydrogen nozzle from the hydrogen port and the whole filling process is completed.
For the measurement of mass flow rate, volume flow rate, temperature and density of cryogenic, high pressure and normal medium. The highest accuracy can reach 0.05 grade.
Hydrogen mass flowmeter is widely used in hydrogen trade measurement fields such as hydrogen dispensers and hydrogen stations.
It is used for highly precise, stable and consistent measurement and monitoring in real time of the gas content/liquid content, gas flow, liquid flow and total flow in natural gas/shale gas.
Based on the principle of centrifugal pump, liquid will be delivered to pipeline after being pressurized to add liquid for vehicle or pump liquid from tank wagon to storage tank.
It can be used to fill high-pressure gas cylinder of L-CNG filling station; It is applicable to cryogenic high-pressure pressurization system to pressurize medium for use.
Rotate the handle to connect vehicle receptacle. The check valve elements in both the refueling nozzle and the receptacle are forced to open with force from each other, in this way, the refueling route is open. When the refueling nozzle is removed, valve elements in both the refueling nozzle and the receptacle will resume to its original position under the pressure of medium and spring, to make sure that complete seal in place and no leakage will occur.
The 35 MPa hydrogen refueling nozzle is designed according to international and national regulations. It has good compatibility. Its body material is made of high strength stainless steel, sealing materials use specifically made seal pieces. Its appearance is ergonomical
Valve element can be driven via electromagnetic force generated by solenoid coil to achieve the valve opening and closing, so as to open or cut off medium access. In this way, automation control of gas filling process is achieved.

It is installed on the filling/discharging hose of LNG filling device. When it bears a certain external force, it will be automatically cut off to prevent leakage. In this way, fire, explosion and other safety accidents caused by unexpected fall-down of gas filling device or breaking of filling/discharging hose due to man-made misoperation or operation against regulations can also be avoided.

Dual fuel gas supply system takes cryogenic LNG as the source for fuel gas. LNG is stored in storage tank or liquid cargo tank, and is transferred to the fuel gas supply system by transfer pump or PBU of the tank. Since the fuel gas for engines should be in gas phase with normal temperature and the LNG withdrawn from the tank is still in cryogenic phase. So a vaporization and heating process is required to ensure the supplied fuel gas meets the temperature required by engines.
