Experimental Study on the Leakage Rate of Pressure Regulator Based on FTA

According to the situation where the leakage rate of a certain model of satellite pressure regulator is near the required indicators and the leakage sealing margin is not high. The article first analysed the structural characteristics of the product and carried out corresponding analysis and experimental work; Secondly, corresponding improvement measures and related experimental verification will be proposed based on the experimental results. Finally, the improved solution was assembled into the product and its leakage rate was tested during the product development process. The test results showed that the sealing margin of the improved product's external leakage rate was significantly improved.
