Abstract
Hydrogen centralized management safe venting system of the present invention is made up of pneumatic operated valve 1, temperature, pressure measuring point 2, hand stop valve 3, electromagnetic valve 4 and respective line.High altitude discharge method according to the principle of centralized management safety dumping, is applied to big flow multiple spot hydrogen discharge system by the system first, is prepared, carries out and ending phase needs low temperature hydrogen to be processed between test cell and liquid hydrogen in engine test for safety dumping.
Description
Technical field
The present invention manages safe venting system concentratedly for a kind of hydrogen, and the hydrogen for certain model oxyhydrogen engine test concentrates peace
The full safety row for discharging, may be equally applicable for other and following new model hydrogen-oxygen rocket or dynamical system test hydrogen
Put.
Background technology
Tank and pipeline pre-cooling stage, electromotor pre-cooling stage, experimental stage, off-test rank in oxyhydrogen engine test
Section or emergency cutoff stage, it is required to process different flow, the low temperature hydrogen of different temperatures between test cell and liquid hydrogen.Hydrogen discharge
During the problem of most critical be to ensure that its safe discharge, the system concentrates the method for discharge to solve well using high-altitude
This problem.
Content of the invention
The technology solve problem of the present invention：The invention provides a kind of hydrogen concentrates pipeline safety dumping technology, mainly solve
Following problem：
