阀座的密封结构SealingConstructionofValveSeat

浮支球阀采用特殊设计的双斜面弹性密封圈。有效的降低了球体与密封圈之间的磨擦力，减少了操作力矩。当介质压力较小时，密封圈与球体接触面积较小，故有较大的密封比压，确保可靠密封。当介质力较大时，密封圈与球体接触面积也相应增大。故密封圈能承受较大的介质推力而不会损坏，确保可靠密封（如图一所示）

当介质的冲刷力较大时，特别设计的阀座防冲刷结构能有效的防止介质的冲刷，确保封圈的使用权用寿命。（如图二）

对于低压，超低压或真空工况用球阀，因介质本身的压力不能确保阀座可靠密封，而预紧力长期使用后又会衰减，特别设计的弹簧加载阀座密封结构。能确保阀门长期可靠使用。（如图三）

由于d1、d的面积差在上游介质的压力作用下形成活塞效应，使阀座与球体紧密接触而密封。

辅助密封结构AuxiliarySealingConstruction

根据用户的需要，球阀的阀座及阀杆的密封部位，可加装注脂阀。当密封部位因擦伤而引起泄露时，通过注脂阀注入密封脂，可起瞬时密封作用。（如图五）

阀杆防冲出及有效密封结构 Extruding-Protection/ValidSealing Construction fortheStem

阀杆采用下装式、设置带有密封垫片的倒密封结构，倒密封的密封力随阀腔介质压力的增高而增大，从而确保阀杆的密封效果。当阀腔异常升压时，阀杆不会被冲出。填料采用设计合理的V型结构，能将阀腔内部的介质压力及外部压盖的锁紧力有效的转化成阀体的密封力。（如图七）

耐火结构IncombustibleConstruction

根据用户的需要，球阀可设计成耐火结构。当万一发生火灾而使封圈烧损时，球阀的各个密封部位均能形成金属的硬密封结构，有效阻止介质的扩散，防止火灾扩大。（如图八）

球阀的全通径及缩径结构

All-DiameterConstruction&CrinkledDiameterConstructionfortheBallValve

为满足客户的不同需求，球阀设有全通径及缩径两大系列。全通径球阀的通道内径与管线内径一致，不但流体阻力最小，出便于管道清理。而缩径球阀的流体阻力比相同口径截止阀的流体阻力要低很多，重量比相同口径的球阀要轻30%左右，有效的降低了生产成本及价格，因而逐步得到了较为广泛的使用（如图六）

防静电结构Static-ProtectingConstruction

根据用户需要，球阀可以设计防静电结构，即在球体与阀杆，阀杆与阀体之间设置导电弹簧，使阀门在开启过程中产生的静电能通过所设置的静电通道传入管路导入地下，达到清除静电的目的，避免静电打火点燃易燃介质，确保系统安全。（如图九）

防止误操作结构

对安装在野外的或防止非工作人叫误操作的，以及在有些振动较大的场合手柄受到撞击易产生误动作的阀门，在阀门的全开或全关的位置设有锁定孔，需要时可加锁，起到安全保险作用。（如图十二）

水压、气压密封检测PressureTest检测球阀有以下3种检测方式

(1）阀体强度检测（ShellHydrostaticTest）的压力Mop(Maximumoperatingpressure）要比被检测的阀门对压力等级高1.5倍以上且不同型号的阀门都有规定的检测时间，加压后要检查阀体材料以及焊接缝细是否有泄漏，请参照表(7.1)所示，其型号压力检测方法及其规定的时间，此检测要在阀门半开状态下侧加水压，使内部充分达到检测压力。

(2）密封水压检测(Seat HrdrostaticTest)压力，要超过阀门使用压力等级的1.1倍的水压，请参照表(7.2)所示，在不同的型号都有其规定的不同的时间内，加压后密封是否有外漏。此检测在阀门半开状态下两侧充分加压后关闭阀门，侧方向(Directional/unidireitional)继续加压，在相反的方向检查密封是否泄漏。(3）气压密封泄漏检测（AirSeatTest)气压密封漏检测是以80psig（6kgf/cm）非活性煤气(Inengas)或空气充分加压后关闭阀门，在阀门一侧检查阀门是否泄漏：

球阀的种类型号Thetypeofballvalvetype

双向流硬碰硬旋球阀是结合球阀的优越密封性能与蝶阀的优势结构性能研发而成，其即拥有球阀双向密封、可调节、寿命长的实用优势，又具备蝶阀体积小、重量轻的结构优势。其实质为蝶式结构偏心半球阀！密封原理结合了固定球阀的前端密封与偏心蝶阀的强制密封，从而实现了高低压双向切断。在密封副的两个密封面上可根据不同的硬度需要运用太空等离子喷涂、以太激光溅射、真空保护渗复堆等先进工艺形成马氏体不锈钢、奥氏不锈钢、硬质合金、金属陶瓷、人造金刚石等梯度功能材料。能自动对正中心（自适应），自动越程补偿磨损，自动加以极高密封比压，瞬间关闭、瞬间打开密封副间无摩擦，打开时阀芯投影不断膨胀并前进，结构短、体积小可制造大口径、特大口径、超大口径、超大口径的阀门，运输、安装、维护检修方便、运行可靠等一系列优点，成为阀门行业的一次重大的技术革命。

主要型号规格球阀的（厂标）结构长度表

StructuralLengthListforBallValvesonMainSpecifications(EmbleMarks)在长期的生产实践中，我们发现现有的球阀结构长度标准往往不能适应用户的实际需求，因此，本着一切为用户着想的经营理念，我们综合用户广泛需求及被实际采用的球阀结构长度的制定成表，作为本厂定型长度标准供用户选型时参考，选用该表尺寸请在订货合同中注明。
