补充资料：通用机械：旋塞阀
用带通孔的塞体作为启闭件的阀门。塞体随阀杆转动﹐以实现启闭动作。小型无填料的旋塞阀又称为“考克”。旋塞阀的塞体多为圆锥体(也有圆柱体)﹐与阀体的圆锥孔面配合组成密封副。旋塞阀是使用最早的一种阀门﹐结构简单﹑开关迅速﹑流体阻力小。普通旋塞阀靠精加工的金属塞体与阀体间的直接接触来密封﹐所以密封性较差﹐启闭力大﹐容易磨损﹐通常只能用于低(不高于1兆帕)和小口径(小于100毫米)的场合。为了扩大旋塞阀的应用范围﹐已研制出许多新型结构。油润滑旋塞阀是最重要的一种(见图 油润滑旋塞阀 
)。特制的润滑脂从塞体顶端注入阀体锥孔与塞体之间﹐形成油膜以减小启闭力矩﹐提高密封性和使用寿命。它的工作压力可达64兆帕﹐最高工作温度可达325℃﹐最大口径可达600毫米。
旋塞阀的信道有多种形式。常见的直通式主要用于截断流体。三通和四通式旋塞阀适用于流体换向。
