The utility model relates to a new type of heat recovery valve for high temperature composite packing, including a valve body, a valve cover, a valve plate and a stem. The upper part of the valve cover is set up in the valve body. The valve plate is set in the valve body and the valve stem is connected with the valve plate. The valve rod is penetrated into the filling letter, and the valve rod is arranged in the gap between the valve rod and the filling letter. The packing includes a number of flexible graphite seal rings and a teflon seal ring, and a packing gland is set at the top of the sealing packing, and a flexible graphite support ring is set at the bottom of the seal packing. Compared with the existing technology, the utility model uses the flexible graphite and the Teflon material as the filler. In the case of guaranteeing the sealing performance, the utility model has the function of fully protecting the valve stem, and the good lubrication performance can reduce the torque of the valve switch, and the pressing nut is set as the auxiliary sealing means, and the valve is used as the valve. Slight leakage can be achieved by tightening the nut to re seal the valve.
【技术实现步骤摘要】
新型高温组合填料热采膨胀阀
本技术涉及高温热采井口领域,具体涉及一种新型的热采膨胀阀。
技术介绍
目前,公知的热采膨胀阀密封填料采用钢丝缠绕石墨垫片组合密封填料,这种结构密封填料没有弹性,回复性能差,密封填料安装完成后阀门扭矩急速增加,使得阀门难以开启;且缠绕钢丝会对阀杆部分造成拉伤,造成阀门开关过程中,出现渗漏的情况;且石墨会随着阀门的使用逐渐的产生流失,阀门容易发生泄漏。
技术实现思路
本技术的目的在于:提供一种新型填料组合热采膨胀阀,阀门开关力矩轻,对阀杆无拉伤,密封可靠,性能优越。本技术的技术解决方案是:新型高温组合填料热采膨胀阀,包括阀体、阀盖、阀板、阀杆,阀盖上部设置填料函,阀板设置在阀体内,阀体内设置与阀板相连接的阀杆,阀杆穿入填料函内,在所述的阀杆与填料函之间的空隙内设置密封填料,所述的密封填料包括若干柔性石墨密封圈与特氟龙密封圈,柔性石墨密封圈与特氟龙密封圈两两紧密贴合成组设置,在密封填料的顶部设置填料压盖,密封填料的底部设置柔性石墨支撑圈。所述柔性石墨密封圈与特氟龙密封圈圈体截面呈倒V形,柔性石墨密封圈的底面被特氟龙密封圈的顶面卡入并紧密接触。所述的填料压盖上侧设置压紧部,所述压紧部为圆筒形,圆筒的上表面封闭,在圆筒的上表面中央设置令阀杆伸出的通孔,圆筒的下表面与填料压盖接触。所述压紧部顶面四周设置螺孔,螺孔内设置压紧螺母。本技术与现有技术相比,其使用柔性石墨与特氟龙材料作为填充物,首先上述材料具备良好的自润滑性,在保证密封性能的情况下,其对阀杆起到了充分保护的作用,且良好的润滑性能可以减少阀门开关的力矩,且设置了压紧螺母作为辅助密封手段,当阀 ...
