摘　　要：为解决"G"型钻具浮阀阀芯的阀盖与其阀座的端面密封在弹簧自动复位时始终存在着的渗漏现象,研制了新型"F"型钻具浮阀。新型"F"型钻具浮阀的阀芯,采用了密封箭锥面的金属密封形式,其密封性能较之"G"型钻具浮阀阀芯采用的端面密封有了显著的提高,特别是在静水压力试验时的密封性能,增加了密封件的寿命及安全性能。In order to solve the leakage phenomenon between valve cap of ' G' type drill pipe float valve and end surface seal of valve seat,a new 'F' type drill pipe float valve was studied. The valve core of the ' F' type drill pipe float valve adopt metal seal in the taper surface of seal arrow,and its leakproofness,especially in static pressure test,was improved prominently by comparing with end surface seal of 'G' type drill pipe float valve,the life and safety fea-ture of sealing member were increased.
