摘要: 介绍了一种新型矿用避难硐室防护密闭门,采用专用抗冲击有限元计算软件对门体强度进行了计算。结果表明,结构设计可实现防护密闭门抵抗冲击波、气密防毒、开闭灵活以及隔绝高温等功能,能够确保其在井下的安全可靠性。Abstract: This paper introduces a new type mine-used protective sealing valve. The strength of valve is calculated by using special anti-impact finite element software. The results shows that the structure design realizes the functions of shock wave resistance, gas-proof, flexible opening and closing and high temperature insulation to make sure the safe reliability in coal mine underground.
