Control system for tire blank shaping pressure stability

The utility model provides a control system for tire blank shaping pressure stability, which comprises a pipeline module, the pipeline module comprises a shaping nitrogen inlet pipeline and a capsule connected with the shaping nitrogen inlet pipeline, the shaping nitrogen inlet pipeline is provided with a one-way valve, and the capsule is connected with the one-way valve. A self-overflow type balance valve is further arranged between the one-way valve and the capsule, and the self-overflow type balance valve is used for controlling the pressure in the shaped nitrogen inlet pipeline; and the program module is used for setting the pressure value of the shaped nitrogen inlet pipeline. Due to the design of the pipeline module, the tire blank shaping pressure peak value can be controlled, so that the roundness of a tire finished product is high, and the resonance noise of a tire cavity is reduced. 本实用新型提供一种用于轮胎胎胚定型压力稳定性的控制系统，包括管路模块，所述管路模块包括定型氮气进路管路和与所述定型氮气进路管路连接的胶囊，所述定型氮气进路管路上设置有单向阀，所述单向阀与所述胶囊之间还设置有自溢式平衡阀，所述自溢式平衡阀
