球阀使用说明
球阀使用说明书Q41F 浮动式球阀浙江福泰阀门有限公司球阀(Ball Valve)球阀是由旋塞演变而来的，它的启闭件为一个球体，利用球体绕阀杆的轴线旋转90度实现开启和关闭的目的。
球阀在管道上主要用于切断、分配和改变介质流动方向，设计成V 形开口的球阀还具有良好的流量调节功能。
球阀不仅结构简单，密封性好，而且在一定的公称通径范围内体积较、重量轻、材料耗阀门品种之一。
特别是在美、日、德、法、意、西、英等工业发达国家，球阀的使用非常广泛，使用品种和数量仍在继续扩大，并向高温、高压、大口径、高密封性、长寿命、优良的调节性能以及一阀多功能方向发展，其可靠性及其他性能指标均达到较高水平，并已部分取代闸阀、截止阀、节流阀。
随着球阀的技术进步，在可以预见的短时间内，特别是在石油天然气管线上、炼油裂解装置上以及核工业上将有更广泛的应用。
此外，在其他工业中的大中型口径、中低压力领域，球阀也将会成为主导的阀门类型之一。
球阀结构图球阀的优点是：（1）具有最低的流阻（实际上为零）。
（2）因在工作时不会卡住（在无润滑剂时），故能可靠地应用于腐蚀性介质和低沸点液体中。
（3）在较大的压力和温度范围内，能实现完全密封。
（4）可实现快速启闭，某些结构的启闭时间仅为0.05~0.1s，以保证能用于试验台的自动化系统中。
快速启闭阀门时，操作无冲击。
（5）球形关闭件能在边界位置上自动定位。
（6）工作介质在双面上密封可靠。
（7）在全开和全闭时，球体和阀座的密封面与介质隔离，因此高速通过阀门的介质不会引起密封面的侵蚀。
（8）结构紧凑、重量轻，可以认为它是用于低温介质系统的最合理的阀门结构。
（9）阀体对称，尤其是焊接阀体结构，能很好地承受来自管道的应力。
（10）关闭件能承受关闭时的高压差。
（11）全焊接阀体的球阀，可以直埋于地下，使阀门内件不受浸蚀，最高使用寿命可达30年，是石油、天然气管线最理想的阀门。
由于球阀的以上优点，所以适用范围很广，球阀可适用于：（1）公称通径从8mm到1200mm。

Thevalve can be mounted in any position so that the handle, gear, or actuator has proper clearance, allows foroptimal drainage, can be easily accessed, and the open/close indicator can be viewed. If the gear is equipped witha chain wheel, the valve shall be mounted in a way so that the chain does not come in contact with the valve orpipeline.2.3Before installation of the valves, the pipe must be flushed clean of dirt, burrs, and welding residues. Failure to doso can cause the seats, sealing surfaces, and internal polish to be damaged.2.4The pipe must be free from tension and in proper alignment.2.5Before installation of the valves, check to ensure that all connections are free from defects.2.6Be sure to consult with supplier of your clamps and gaskets to be used on the hygienic ends for the propermaterial, pressure rating, and clamp torque for your process. Over torqueing clamps may result in damage to the ferrule end.2.7Disassembly of the valve is not necessary for tube end valves. However, caution should be taken to ensure thatthe heat source does not come in contact with the sealing components of the valve in excess of the sealingcomponent temperature limitation.3VALVE OPERATION3.1MANUAL3.1.1HandleTo open the valve, turn the handle counter-clockwise until the handle is parallel with the pipeline andthe handle has contacted the handle stop.To close the valve, turn the handle clockwise until the handle is perpendicular with the pipeline and thehandle has contact the handle stop.A handle lock is incorporated into the handle. To use slide the lock into the mounting pad, in the fullopen or full closed position. Insert an appropriate size lock or hasp into the hole in the handle. If it canbe performed safely, try to turn to ensure that the valve has been locked properly.3.1.2GearTo OPEN the valve; turn the hand wheel counter-clockwise. The indicator will be pointing to the openposition and stop rotating when fully opened. The flow can be adjusted by stopping the indicatoranywhere between open and close.To CLOSE the valve; turn the hand wheel clockwise. The indicator will be pointing to the close positionand the hand wheel will stop rotating when fully closed. The flow can be adjusted by stopping theindicator anywhere between open and close.3.2AUTOMATEDA-T Controls 77-Series Ball Valves can be mounted with quarter turn actuators. Valves with actuatorsshall be checked for proper valve stem alignment. Angular or linear misalignments may result in highoperational torque and unnecessary wear on the valve stem. See the actuator IOM for information onoperating the actuator.4DISASSEMBLYWARNINGCAUTION, FLUIDS CAN BE TRAPPED IN THE BODY OF THE VALVE, POSSIBILY UNDER HIGH PRESSURE. FOR YOUR SAFETY, IT IS IMPORTANT THAT PRECAUTIONS ARE TAKEN BEFORE REMOVAL OF THE VALVE FROM THE LINE OR ANY DISASSEMBLY.4.1Remove actuator or gear if equipped.4.2Care should be taken to not damage the surface finish of the valve components.4.3Remove the ends (2) from the body by removing the body bolts (18) and body nuts (19).4.4Remove the seat (4) and body gasket (5) from both sides of the body (1). Once removed, with the valve in the fullyclosed position, the ball (3) should slide freely out of the body (1).4.5If equipped, remove the handle nut (13), handle (15), and handle stop assembly (22).4.6While holding the stem (7) stationary, remove the packing nut (13). Once removed, the locking saddle (12),Belleville washers (11) and packing bushing (10) should be free to remove.4.7While holding the bottom of the stem (7), push the stem (7) through the inside of the valve body (1).4.8Remove the packing set (8) and stem seal (6).4.9Inspect all components for damage and if necessary clean or replace.5ASSEMBLY5.1Care should be taken to not damage the surface finish of the valve components.5.2Place stem seal (6) on the stem (7) and install it by going through the body (1). Insert V-Style packing set (8) overstem (7) with the V pointing away from the valve (see Bill of Materials for correct orientation).5.3Install the packing gland (10), the Belleville washers (11), locking saddle (12), and packing nut (13). While holdingthe stem (7), tighten the packing nut (13) to the torque listed in the Fastener Torque Chart. Tighten further ifneeded in order to be able to bend the locking saddle (12) over a flat side of the packing nut (13).5.4Ensure that the stem (7) is in the closed position with the bottom tang parallel with the flow of the valve. Insert aseat (4) and body gasket (5) in one side of the body (1). Carefully slide the ball (3) into body (1) and insert the other seat (4) and body gasket (5).5.5Assemble ends (2) onto body (1). Insert all body bolts (18) and nuts (19) into valve and tighten to finger tight,making sure that the ends (2) are flat against the body (1). Tighten all bolts (18) (on both sides for valves 2-1/2”- 4”) from the nut (19) side (if equipped) in a star pattern to 50% of the final torque shown in the Fastener Torque Chart. Using the handle (15) or an adjustable wrench, cycle the valve 3 times. Tighten all of the body bolts (18) to the final torque in a star pattern. Cycle the valve 3 times again. Check each body bolt torque (18) and tighten if needed a final time. It is acceptable for the torque to relax slightly over time due to relaxation of the polymer components, but the valve will still seal properly. If leakage is detected, repeat the steps for tightening the body bolts.5.6If required, assemble the handle stop assembly (16), handle (15), and handle nut (13).Valve SizeTorque of Body Bolts (In-lbs.)

1.7阀门往管道上安装时，在法兰间应垫进合适的垫片，取相应的规格的螺栓把法兰对角均匀拧紧。
1.8如阀门安装后发现阀杆密封处有渗漏，可能是在运输过程中震动和温度变化引起填料松弛，拧紧填料压盖
螺母即可，并注意给填料加润滑油，以减轻操作力矩。
1.9阀门的开启和关闭由手柄（手轮）来控制，当顺时针旋转手柄（手轮）时球体在阀杆的作用下顺时针旋转
运动关闭阀门，逆时针则旋转手柄（手轮）则开启阀门。
1.10阀门可安装在任意位置，介质可从任意端进入。
1.11如阀门为非手动装置，必须设置好执行机构的空间位置，以便在意外情况的人工操作及维修，并在正式投
产前对电动驱动装置进行检查和测试。
2、储存与维护保养
2.1在干燥通风的室，两端应盖上防尘盖，以保证阀门的腔清洁。
2.2长期存放应在阀门密封面涂防锈油，并定期检查。
2.3 大型阀门存放在室外保管时，应将其支撑起来，不要与地面接触，并用塑料薄腊覆盖保护。
2.4长期存放的阀门重新使用时，应检查填料是否失效，并对各转动部位加注润滑油。
2.5阀门在使用中应定期检查以保证阀门的使用性能，包括定期拧紧阀门填料压盖螺母，以补偿阀杆磨损；如
果阀门与电动装置使用无松动联轴器，则要先松开联轴器，然后拧紧填料压盖螺母。
2.6阀门的保修期。
阀门在投入使用一年，但不超过发货18个月，如确因材料缺陷，制造质量，在正常使用
中的损坏，经本公司质检部门确认后，在保修期负责保修，包括更换垫片、填料、球体（按需要）、阀座等密封付。
2.7保持阀门的工作环境清洁，以延长阀门的使用寿命。
★2.8球阀在使用过程中应全开或全关，禁止作调节阀用，否则会缩短阀门的使用寿命。
