One-way valve for rail attitude control power system

According to the one-way valve for the rail attitude control power system, the sealing form of the valve element and the valve body is changed by changing the structure of the valve element. After the sealing mode is changed, the production of the valve core of the one-way valve can be completed by single machining without a hot pressing process, and the required non-metal sealing element is changed into a standard part O-shaped ring which is easy to purchase, so that the production efficiency, the opening and closing performance and the service life of the one-way valve can be improved, and the normal operation of a rocket launching task can be ensured. 本发明提供一种轨姿控动力系统用单向阀，通过改变阀芯的结构，进而使得阀芯与阀体的密封形式得到改变。密封形式改变以后，单向阀阀芯的生产，不再需要热压工艺，单一的机加工即可完成，所需要的非金属密封件，也更改为易于采购的标准件O型圈，从而能够提高单向阀的生产效率、启闭性能和使用寿命，能够确保火箭发射任务的正常运行。
