Description

流体遮断安全装置 技术领域
本发明为一种流体遮断安全装置，特别是指一种借由该遮断座将接头与阀体的组接端相互组接的装置。
背景技术
目前，氧、氮、氦、氩、笑气、乙炔、天然气、二氧化碳、液化石油气等气体被广泛应用于工业、医疗、消防或居家等范畴，为求储存、运送与使用的便利，大都将其以高压形式封存于高压铝瓶、钢瓶等容器中，而高压气体容器为一瓶体，该瓶体上设有一让高压气体释出的气嘴，该气嘴在高压气瓶储存时呈密封状态，待使用时便拆除密封并装上气体管路或调节阀，以气体管路或调节阀的启闭控制瓶内高压气体持续释出或中断释出，并透过气体管路将高压气体输至施作场所。
然而，在自然灾害中，强风的刮卷吹袭与地震的摇晃震动甚为容易造成物体的移位、脱落、或倾倒，另外，物体遭受突发的人为意外撞击也会导致相同的情形发生，因而已使用的高压气瓶在强风、地震或人为意外中极可能会造成连结的气体管路或调节阀因强烈摇晃震动而松脱、断开或者因撞击而破裂，与气体管路或调节阀分离的高压气瓶内部气体便会由开放状的气嘴不断外泄，或者从气体管路破损处泄出，气体外泄易导致周遭人员吸入性中毒、引发火灾与爆炸等等灾害，严重危害生命财产安全。因此，针对上述所言，如何研发出一种能由于火灾、强风、地震或人为意外而导致连结的气体管路或调节阀因强烈摇晃震动而松脱、断开，又或者因撞击而产生破裂等情形，而能发挥安全防护效果的装置，需相关业者更进一步的思考，该如何改良、改善才能够更符合社会大众的使用。
技术问题
有鉴于此，本发明的主要目的在于提供一种流体遮断安全装置，是借由该遮断座将接头与阀体的组接端相互组接，当遮断座受到外力影响时，该接头会与组接端脱离分开，使该第一容纳区内的流体压力失衡，令流体大量流向容设区内并推抵挡止件封闭容设区与第二容纳区之间相连通之处，以防止流体继续流向第二容纳区而导致流体不断外泄，借此以防止灾害扩大，降低人们生命财产之损害程 度。
技术解决方案

本发明进一步的技术特征，其中该遮断座材质为低熔点塑料，并借由此低熔点塑料材质特性，使该遮断座受高温熔化时，令接头与阀体脱离，使该第一容纳区内的流体压力失衡，令流体大量流向容设区内并推抵挡止件封闭容设区与第二容纳区之间相连通之处，以防止流体继续流向第二容纳区而导致流体不断外泄。
本发明进一步的技术特征，其中该容槽的槽底壁面间隔剖设复数剖沟。
本发明进一步的技术特征，其中该容设区设有一弹性件，而该弹性件弹抵挡止件，且该挡止件具有一凸柱，该凸柱组设于弹性件内，令该挡止件受弹性件限位。

本发明进一步的技术特征，其中该挡止件可为滚珠或塞子。
有益效果
本发明借由该遮断座将接头与阀体的组接端相互组接，当遮断座受到外力影响时，该接头会与组接端脱离分开，使该第一容纳区内的流体压力失衡，令流体大量流向容设区内并推抵挡止件封闭容设区与第二容纳区之间相连通之处，以防止流体继续流向第二容纳区而导致流体不断外泄，借此以防止灾害扩大，降低人们生命财产之损害程度。因此本发明可说是一种相当具有实用性及进步性的发明，相当值得产业界来推广，并公诸于社会大众。

本发明的实施方式
为了清楚说明本发明所能达成上述的目的及功效，兹搭配图示就本发明的实施例加以详细说明其特征与功效。请参阅图1至图6所示(在图3、图4、图6中箭头所表示为流体的行进方向，而图5中箭头所表示为接头受外力强力的碰撞或撞击)，图中显示一种流体遮断安全装置，其包括一阀体1，其一端设有一第一容纳区11，另一端则设有一第二容纳区12，而该阀体1内具有一容设区13，且该容设区13连通第一容纳区11及第二容纳区12，该第一容纳区11具有一组设端111，而该第二容纳区12具有一组接端121；一挡止件2，其设置于容设区13内；及一遮断座4，其具有一容槽41及一接头3，该组接端121组设于容槽41。
前述为本发明主实施例的主要技术特征，其对应本案权利要求第一项的内容，得以详知本发明的目的与实施型态，而其余附属权利要求所述的技术特征是为对申请权利要求第一项内容的详述或附加技术特征，而非用以限制权利要求第一项的界定范围，应知本案权利要求第一项不必要一定包含其余附属权利要求所述的技术特征。
请参阅图2所示，该遮断座4另具有贯穿容槽41的一穿孔42，而该接头3具有一连接部31及一卡抵部32，且该连接部31一端与卡抵部32相连接，该接头3的连接部31穿过穿孔42并局部外露于遮断座4的一端，且该接头3的卡抵部32卡抵于容槽41内，而该遮断座4于连接部31外露的另一端组设于第二容纳区12的组接端121(如图3所示)。
请参阅图3所示，本发明的遮断座4是借由低熔点塑料材质所制成，并借由 此低熔点塑料材质特性，使该遮断座4受到超过可耐热的高温而熔化时，令该接头3与阀体1脱离，使该第一容纳区11内的流体压力失衡，令流体大量流向容设区13内并推抵挡止件2封闭容设区13与第二容纳区12之间相连通之处，以防止流体继续流向第二容纳区12而导致流体不断外泄(如图4所示)。
请参阅图1及图2所示，本发明容槽41的槽底壁面间隔剖设复数剖沟43，再请参阅图5所示，当接头3受到外力的强力碰撞及撞击时，该接头3的卡抵部32则迫抵挤压容槽41的槽底壁面，且位于容槽41槽底壁面的各剖沟43因受到迫抵挤压的影响，进而导致穿孔42的孔径变大，并使得该接头3整个脱离遮断座2的容槽41，使该第一容纳区11内的流体压力失衡，令流体大量流向容设区13内并推抵挡止件2封闭容设区13与第二容纳区12之间相连通之处，以防止流体继续流向第二容纳区12而导致流体不断外泄(如图6所示)。
请参阅图3及图4所示，该容设区设有一弹性件5，而该弹性件5弹抵挡止件2，且该挡止件2具有一凸柱21，该凸柱21组设于弹性件5内，令该挡止件2受弹性件5限位，本发明是借由挡止件2的凸柱21组设于弹性件5内，使该挡止件2受到弹性件5的限制位移，以防止该挡止件2受到第一容纳区11流向容设区13的流体推移，让挡止件2不会任意的在容设区13内滚动位移。
请参阅图3所示，该容设区13进一步设有一输入孔131及一输出孔132，该输入孔131与第一容纳区11相连通，而该输出孔132与第二容纳区12相连通，当流体产生外泄现象时，流体于第一容纳区11经由输入孔131大量流向容设区13内，且流体于容设区13内推动挡止件2，并令挡止件2封闭容设区13的输出孔132，使流体被封阻于容设区13内，让流体不再继续流向第二容纳区12而导致流体持续外泄(如图4所示)。
请参阅图2所示，该组接端121外周侧设有一外螺纹1211，而该容槽41周侧槽壁面环设一内螺纹411，该容槽41的内螺纹411螺锁于组接端121的外螺纹1211，该遮断座4与穿组于遮断座4容槽41的接头3，透过容槽41的内螺纹411而螺锁固定于组接端121的外螺纹1211(如图3所示)。
请参阅图3所示，本发明的挡止件2可依业内人士于制造时，搭配该阀体1内部构造而依照需求制作为滚珠的型态或者是塞子的型态(本图标的挡止件2所表示为滚珠的型态)。
借由上述，请参阅图2及图3所示，当火灾或地震等灾害发生时，人们往往都会先逃离灾难现场跑往安全场所避难，而基于人们往往会忘记先关闭高压流体容器开关，如此于火灾发生时，外漏的高压流体(如瓦斯)所引发的气爆往往让损害扩大，在本发明中，该遮断座4是采用低熔点特性的塑料材料制成，如此，当周遭环境处于高温闷烧的阶段时，该遮断座4即会于第一时间受热而导致熔化并启动防护装置，使得穿组于遮断座4容槽41内的接头3将径行与第二容纳区12的组接端121脱离，同时，令该第一容纳区11内的流体压力失衡，而使流体大量流向容设区13内，且该挡止件2封闭容设区13的输出孔132，让流体被封阻于容设区13内，使流体不再继续流向第二容纳区12而导致流体持续外泄，借此以防止灾害扩大，降低人们生命财产的损害程度(如图4所示)。请参阅图5所示，且若遭遇地震或人为意外而导致连接管路的接头3受到强力的碰撞或撞击时，导致该接头3的卡抵部32因受力而迫抵挤压容槽41的槽底壁面，并使得贯穿容槽41的穿孔42受到容槽41槽底壁面间隔剖设的复数剖沟43影响而使得孔径变大，令该接头3的卡抵部32脱离遮断座4的容槽41，同时，令该第一容纳区11内的流体压力失衡，而使流体大量流向容设区13内，此时，本发明会于受到强力 碰撞或撞击的同时而在第一时间启动防护装置，令该挡止件2封闭容设区13的输出孔132，让流体被封阻于容设区13内，使流体不再继续流向第二容纳区12而导致流体持续外泄，借此以防止灾害扩大，降低人们生命财产的损害程度(如图6所示)。
由上所述仅为用以解释本发明的较佳实施例，并非企图据以对本发明做任何形式上的限制，是以，凡有在相同的发明精神下所做有关本发明的任何修饰或变更者，为其他可据以实施的型态且具有相同效果者，皆仍应包括在本发明意图保护的范畴内。

  2. 根据权利要求1所述的流体遮断安全装置，其特征在于，该遮断座另具有贯穿容槽的一穿孔，而该接头具有一连接部及一卡抵部，且该连接部一端与卡抵部相连接，该接头的连接部穿过穿孔并局部外露于遮断座的一端，且该接头的卡抵部卡抵于容槽内，而该遮断座于连接部外露的另一端组设于第二容纳区的组接端。
  3. 根据权利要求1所述的流体遮断安全装置，其特征在于，该遮断座材质为低熔点塑料，并借由此低熔点塑料材质特性，使该遮断座受高温熔化时，令接头与阀体脱离，使该第一容纳区内的流体压力失衡，令流体大量流向容设区内并推抵挡止件封闭容设区与第二容纳区之间相连通之处，以防止流体继续流向第二容纳区而导致流体不断外泄。
  4. 根据权利要求2所述的流体遮断安全装置，其特征在于，该遮断座材质为低熔点塑料，并借由此低熔点塑料材质特性，使该遮断座受高温熔化时，令接头与阀体脱离，使该第一容纳区内的流体压力失衡，令流体大量流向容设区内并推抵挡止件封闭容设区与第二容纳区之间相连通之处，以防止流体继续流向第二容纳区而导致流体不断外泄。
  5. 根据权利要求4所述的流体遮断安全装置，其特征在于，该容槽的槽底壁面间隔剖设复数剖沟。
  6. 根据权利要求1至5中任一项所述的流体遮断安全装置，其特征在于，该容设区设有一弹性件，而该弹性件弹抵挡止件，且该挡止件具有一凸柱，该凸柱组设于弹性件内，令该挡止件受弹性件限位。
  7. 根据权利要求1所述的流体遮断安全装置，其特征在于，该容设区进一步设有一输入孔及一输出孔，该输入孔与第一容纳区相连通，而该输出孔与第二容纳区相连通。
  8. 根据权利要求6所述的流体遮断安全装置，其特征在于，该容设区进一步设有一输入孔及一输出孔，该输入孔与第一容纳区相连通，而该输出孔与第二容纳区相连通。
  9. 根据权利要求1所述的流体遮断安全装置，其特征在于，该组接端外周侧设有一外螺纹，而该容槽周侧槽壁面环设一内螺纹，该容槽的内螺纹螺锁于组接端的外螺纹。
  10. 根据权利要求1所述的流体遮断安全装置，其特征在于，该挡止件为滚珠或塞子。
