| 特征
套筒锁紧机构通过连接后旋转套筒而啮合。在使用期间沿地面拖 动接头时，套锁机构能防止意外断开。
套锁机构的设计有助于防止杂物进入内部机构从而在连接或断开 时引起误操作。套筒覆盖挡圈并且在弹簧区域包含了防尘密封件 淬火处理的公插头和套筒以及实心棒状结构造就优质阴接头能zui 大限度的抵抗由于液压和机械冲击所造成的 剥蚀及损坏。
这种抗爆裂BFT密封圈设计用于防止在危险工作状况下出现爆裂 或损坏
耐用球锁机械保证每次都能可靠连接，数个锁定钢球均匀分配工 作负载，同时提供对准及旋转动作从而减小软管扭曲并延长软管 使用期。警告：这类产品不能用作旋转阳接头，在压力下旋转会 导致过度和过早磨损。
LSQ-PT系列接头在连接及断开时使用平齐阀机构操作。这意味 着阀之间的接合能使断开时只损失少量流体，或在重新连接时只 混入少量空气。
LSQ-ＰT接头符合ISO16028标准。 Features
Sleeve locking mechanism is engaged by rotating sleeve after connection ,it prevents accidental disconnection when, The coupling is dragged along the ground,
Sleeve mechanism is designed to help prevent dirt from entering hardened nipplessleevessolid barstock construction for maximum resistance to damage from hydraulicmechanical shock.
This Anti - Blowout Nitrile/PTFE bonded seal is designed to prevent blow - out or damage during sever service conditions
Durable ball - locking mechanism assures reliable connections, every time,A large number of locking balls distributer the work load evenly while providing alignmentswiveling action to reduce hose torqueprolong hose life,CAUTION : These products are not to be used as swivels,Rotation under pressure
will result in excessivepremature wear,
LSQ-PT S eries couplings employ flush valving when connecting or disconnecting,This means that the valves are mated together so that only small amounts offluid can be lost during disconnection or air inclusion during reconnection,
LSQ - PT series conforms to standard of ISO16028 |
