| 英文摘要: |
| The feedback spring rod of the armature assembly is cancelled in the double redundance double nozzle flapper valve (DRDNFV) , and the difficulty of valve core displacement control is increased. Therefore , this paper intends to study the static characteristic of DRDNFV through the AMESet and AMESim simulation. It is explored under the circumstance of the fixed orifices being clogged and experimentally verified on the test bench. The results show that the pressure gain increases and the flow gain decreases with the increasing clogged degree of the fixed orifices on both sides. The zero bias in- creases synchronously with the increasing clogged degree of the unilateral fixed orifice. The experimental results are basically consistent with the theoretical curves and the theoretical correctness of the simulation model is effectively verified. The results can provide the theoretical reference for de- sign, debugging , maintenance and fault diagnosis of DRDNFV. |
