style="white-space:normal;">江苏雷鹏科技发展有限公司</span>是一家从事：天然气、石油、柴 、蒸汽、水等管道开孔/带压堵漏/管道封堵/带压开孔/带压封堵/带压密封的企业。 <br /><br> 带压堵漏的原理<br>带压堵漏的原理就是以液态介质在动态条件下，固态密封材料的密封机理为基本依据。<br>方法是在泄漏部位装设设备，利用密封部位和设备之间形成的腔室，采用的高压注胶工具将密封胶注入腔室，并充满整个腔室空间，使密封胶的挤压力与泄漏介质的压力相平衡，建立一个新的密封结构来堵塞泄漏孔隙各通道，阻塞介质的外泄。<br>阀门的泄漏常发生在填料、法兰密封及阀体上，阀门长时间泄漏可造成阀杆和法兰密封面的冲蚀，终可使阀门报废，加上介质流体的损失，使电厂的消耗增加，成本上升，经济效益下降。如果介质流体有毒、易燃、易爆、腐蚀性等发生外泄漏，则容易发生中毒、火灾、等伤亡事故和加快厂房设备的腐蚀速度，缩短其使用寿命，严重时污染周边环境，破坏电力生产，损害人们的身体健康。泄漏的存在严重威胁着安全生产，使非计划停机事故增多。<br>阀门填料泄漏及原因<br>在阀门的操作和使用过程中，阀杆和填料之间有相对运动，包括旋转和轴向运动。随着开关数量的增加，相对运动次数的增加，以及温度、压力和流体介质特性的影响，阀门填料是易发生泄漏的部位。这是由于填料接触压力逐渐减弱、填料本身老化、弹性丧失等原因造成的。此时，压力介质沿填料与阀杆的接触间隙泄漏，将填料的一部分吹走，并将阀杆长期冲出槽外，使泄漏扩大。<br>法兰泄漏<br>阀门的法兰密封主要依靠连接螺栓的预紧力，通过垫片达到足够的密封比压，防止密封压力流体介质泄漏。其泄漏的原因有很多，如密封垫压力不足、结合面粗糙度不符合要求、垫片变形和机械振动等，都会导致密封垫和法兰结合面泄漏。此外，螺栓变形或伸长、垫片老化、回弹下降、开裂等也会导致法兰表面密封松弛和泄漏。法兰泄漏还存在着密封垫偏差、局部密封压力拧紧力不足、超过密封垫设计极限、法兰拧紧过程中受力不均或两法兰中心线偏差等不可忽视的人为因素，容易发生泄漏。<br>阀体泄漏及原因<br>阀体泄漏主要是由于阀门生产过程中铸造或锻造缺陷造成的，如砂眼、气孔、裂纹等，流体介质的腐蚀和空化也是造成阀体泄漏的常见因素。<br
