设计了一种新型矿井避难硐室防护密闭门,通过对各种密封胶条的理论分析和实验研究表明:硬度为20~25度的矩形硅橡胶密封胶条,在静密封工况下,最佳压缩率为15%~25%。根据最佳压缩量范围并考虑机械加工误差等主要因素,设计了密封结构;通过密封试验,对防护密闭门的关键指标气密性进行了研究,验证了密封结构设计的合理性和可靠性。
設計瞭一種新型礦井避難硐室防護密閉門,通過對各種密封膠條的理論分析和實驗研究錶明:硬度為20~25度的矩形硅橡膠密封膠條,在靜密封工況下,最佳壓縮率為15%~25%。根據最佳壓縮量範圍併攷慮機械加工誤差等主要因素,設計瞭密封結構;通過密封試驗,對防護密閉門的關鍵指標氣密性進行瞭研究,驗證瞭密封結構設計的閤理性和可靠性。

A new protective sealing door for mine refuge chamber was designed;the theoretical analysis and experimental study on variety of rubber strips showed that the optimum compression rate of the rectangular silicone rubber sealing strip with the hardness of 20-25 degree is 15%-25% under the static sealing condition. On this basis, a sealing structure was designed according to the optimum compression amount and in consideration of some factors such as the machining error;experimental study was made on the air tightness of the protective sealing door.
