Consult regarding the filling main valve (with self-locking function) for hydrogen pipeline trucks (torpedo trucks)~~
Thread Content
Dear Ge Weihai, which company is responsible for manufacturing or selling the valves (main valves) for hydrogen pipeline vehicles, those with a self-locking function that automatically shut off under high pressure differences (high flow rates) to prevent the escalation of accidents?~~
It is estimated that a large amount is imported; that person is the agent~~Please help clarify~~ What is the structural principle?~~
This needs to be set up as a chain system; actually, as long as the flow rate is high, a pure hydrogen system remains safe. It seems that a leakage alarm interlock is a simpler solution
