操作和使用 1)、操作前须确认管路和阀已被冲洗过。 2)、阀的操作按执行机构输入信号大小带动阀杆旋转完成：正向旋转1/4圈(900)时，阀关断。反向旋转1/4圈(900)时，阀开启。 3)、当执行机构方向指示箭头与管线平行时，阀门为开启状态；指示箭头与管线垂直时，阀门为关闭状态。 5、 维修 拥有较长的使用寿命和免维修期，将依赖以下几个因素：正常的工作条件、保持和谐的温度/压力比，以及合理的腐蚀数据 注意: ●球阀在关闭状态下，阀体内部依旧存在受压流体 ●维修前，解除管线压力并使阀门处于打开位置 ●维修前，断开电源或气源 ●维修前，将执行机构与支架脱离 1)、填料处得再锁紧 l 若填料涵处有微泄发生，须再锁紧阀杆螺母 (13). l 注意不要锁太紧，通常再锁1/4圈～1圈，泄露即会停止。 2)、更换阀座和密封件. A)、拆卸 l 使阀处于半开位置，冲洗、xx阀体内外可能存在的危险物质. l 关闭球阀，拆掉两边法兰上的连接螺栓和螺母，然后将阀由管线上xx移除。 l 依序拆卸驱动装置-执行机构(20)、连接支架(18)、、防松垫圈(14)、阀杆螺母(13)、蝶形弹片(12)、格南(11) 、耐磨片(10)、阀杆填料(9) l 拆卸体盖连接螺栓(5)和螺母，将阀盖与阀体分离，并拿掉阀盖垫圈(16)。 l 确认阀球(3)在“关断”位置，这可以将其较容易的从阀体拿出，随后取出阀座。 l 由阀体中孔向下轻推阀杆(6)直到xx取出，然后取出O型圈(8)及阀杆下填料(7) 注意：请谨慎操作，以避免擦伤阀杆表面及阀体填料函密封部位 B)、重新组装 l 清洗和检查拆下零件，强烈推荐用备用零件包更换其阀座及阀盖垫圈等密封件 l 按拆卸的相反顺序进行组装。 l 用规定的扭矩，交叉锁紧法兰连接螺栓(5)。 l 用规定的扭矩，锁紧阀杆螺母(13) l 安装执行机构后，输入相应的信号通过旋转阀杆带动阀芯旋转，使阀门至打开和关闭位置。

Operation and use of 1) It must be recognized before the operation of piping and valves have been washed off. 2), valve operation by executing agency the size of the input signal driven rotary valve stem completion: forward rotation 1 / 4 laps (900), the valve off. Counter-rotating 1 / 4 laps (900), the valve is open. 3), when the executing agency of directional arrows in parallel with the pipeline when the valve is open; direction perpendicular to the arrow with the pipeline when the valve is turned off. 5, maintenance Have a long life and maintenance-free period will depend on several factors: the normal working conditions, to maintain a harmonious temperature / pressure ratio, and reasonable corrosion data Note: ● Ball valve closing state, there is still pressure on the internal body fluids ● Maintenance ago, the lift line pressure valve in the open position and to ● Maintenance ago, disconnect the power or gas source ● Maintenance ago, will be the executing agency and the bracket from the 1), was re-packing at lock l If the filling-Han Department has micro-leakage occur, have to re-locking stem nut (13). l Be careful not to lock too tight, usually re-lock 1 / 4 circle to 1 lap, leaking will cease. 2), replacement of the valve seat and seals. A), demolition of l so that valve in a semi-open position, flush, clear body of dangerous substances that may exist inside and outside. l Close ball valve, removed the connection on both sides of the flange bolts and nuts, and then completely remove the valve from the pipeline. l sequentially demolition drive - the executing agency (20), connecting stent (18), and anti-loose washer (14), stem nut (13), butterfly fragments (12), Glam (11), wear-resistant films (10), valve stem packing (9) l Demolition body cover connecting bolt (5) and nuts, valve cover and valve body will be separated and removed the valve cover gasket (16). l confirmed that the ball valve (3) in the "off" position, which can be more easily from the body out, and then remove the valve seat. l from the body in the hole down to nudge stem (6) until it is completely removed, and then remove the O-ring (8) and stem under the filler (7) Note: Please exercise caution in order to avoid scratches the surface of stem and body sealing parts Stuffing B), re-assembly l Cleaning and inspection of removed parts, it is strongly recommended to use the spare parts package to replace its valve seat and valve cover gaskets and other seals l according to the demolition to be assembled in reverse order. l with the provisions of torque, cross-locking flange bolts (5). l with the provisions of torque, locking stem nut (13) l Install the executing agency, enter the corresponding signal by rotating the valve stem is driven spool rotation, so that the valve to open and closed position.
