Abstract

油田平衡式截止阀涉及一种油田输油管道用截止阀,主要是为解决现有的油田输油管道用截止阀关闭费力,且影响密封效果的问题而设计的。它包括阀体、阀瓣、密封套、阀杆、填料、阀盖、阀杆螺母、推力轴承及手柄,这里的阀瓣采用柱塞式结构,在阀瓣内设通孔,在密封套与阀瓣之间设阀瓣上腔。优点是:开关省力,且有利密封。

Description

油田平衡式截止阀
技术领域:本实用新型涉及一种油田输油管道用截止阀。
背景技术:现有的油田输油管道用截止阀工作时由于受介质压力的影响,关闭费力,影响密封效果,特别是中、高压阀门,问题更加突出。
发明内容:本实用新型的目的是提供一种开关省力且密封效果好的油田平衡式截止阀。
上述目的是这样实现的:它包括阀体、阀瓣、密封套、阀杆、填料、阀盖、阀杆螺母、推力轴承及手柄,这里的阀瓣采用柱塞式结构,在阀瓣内设通孔,在密封套与阀瓣之间设阀瓣上腔。优点是当阀瓣升起时介质由阀体经过阀瓣内的通孔流入阀瓣上腔,使阀体和阀瓣上腔压力平衡,因此开关无阻力,开关省力,且有利密封。
附图说明:附图是本实用新型的剖面示意图。
具体实施方式:将阀瓣2和密封套3装在阀体1内,阀杆4与阀瓣连接并用填料5密封,阀盖6装在阀体上,阀杆螺母7装在阀盖的上端,推力轴承8装在阀杆螺母上,手柄9与阀杆螺母连接,阀瓣采用柱塞式结构,在阀瓣内设通孔,在密封套与阀瓣之间设阀瓣上腔10。
