Description

一种拆卸的机械式连接带软胶层的绝缘接头 技术领域
本发明涉及一种绝缘接头领域,具体涉及一种拆卸的机械式连接带软胶层的绝缘接头。
背景技术
在工业装置上管道的腐蚀危险一般比长输管道中的腐蚀危险大,因为在大多数情况下,管道会与钢筋混凝土基础形成腐蚀电池。在不同种类的工业装置区域内能够利用区域阴极保护来克服这种腐蚀危险,所用方法类似于局部阴极保护的方法。受保护的区域是没有限制的,也就是说管道与连接的和分支的管道之间是没有电绝缘的。局部阴极保护的目的不仅是要补偿外部阴极构筑物的电池电流,而且要使被保护的构筑物充分阴极极化,从而满足阴极保护准则要求。在局部阴极保护中,管地电位的变化只与附近的参比电极有关系,而与远方大地电位少有联系。金属-电解质溶解腐蚀体系受到阴极极化时,电位负移,金属阳极氧化反应过电位减小,反应速度减小,因而金属腐蚀速度减小,称为阴极保护效应。利用阴极保护效应减轻金属设备腐蚀的防护方法叫做阴极保护。由外电路向金属通入电子,以供去极化剂还原反应所需,从而使金属氧化反应(失电子反应)受到抑制。当金属氧化反应速度降低到零时,金属表面只发生去极化剂阴极反应。
绝缘接头是管线输送中为防止电化腐蚀,对管线实行阴极保护所需的重要元件,主要应用于燃气输配系统和燃气调压站,其作用是将燃气输配管线的各段间、燃气调压站与输配管线间相互绝缘隔离,保护其不受电化学腐蚀,延长使用寿命。
但是现有焊接式连接的绝缘接头,通常在外形上凹凸不平十分的不美观,焊接过程中,由于温度过高会导致绝缘材料受损,任一部件损坏时,由于不能拆卸的连接关系,导致完好部件也要一并丢弃;使用过程中,由于绝缘接头内部材料表面会损坏管道表面,尤其是焊接点的凹凸不平之处,不利于防腐绝缘保护、造成了极大程度上的浪费、不利于环保。
发明内容
本发明所要解决的技术问题是绝缘接头内部材料表面会损坏管道表面和套管与套筒的可拆卸连接,目的在于提供一种拆卸的机械式连接带软胶层的绝缘接头,解决绝缘接头内部材料表面会损坏管道表面和套管与套筒的可拆卸连接的问题。
本发明通过下述技术方案实现:
一种拆卸的机械式连接带软胶层的绝缘接头,包括两根套管和一个套筒,其特征在于:两根套管和套筒内部均设置软胶层,套管、套筒和体软胶层均为圆柱形空心管形状,软胶层 采用注塑的方式覆盖在套管和套筒的内部,软胶层的外壁与套管和套筒的内壁无缝连接;套管和套筒的表面均设置一层绝缘胶,套管表面的由4种规格的绝缘件嵌合覆盖,绝缘件A的内侧与绝缘件D的外侧连接,绝缘件B和绝缘件C安置在绝缘件A的内侧与绝缘件D的外侧连接的空隙内,绝缘件B嵌在绝缘件A内侧,绝缘件C嵌在绝缘件B和绝缘件D之间并且嵌合处均有空隙,绝缘件B、绝缘件C、绝缘件D均在绝缘件A内侧;套筒表面的由4种规格的绝缘件嵌合覆盖,绝缘件A的内侧与绝缘件D的外侧连接,两个绝缘件E外侧分别嵌合在绝缘件A内侧和绝缘件D内侧并且嵌合处均有空隙,绝缘件F外侧和绝缘件E内侧连接,绝缘件F内侧覆盖在套筒表面,套筒与两根套管之间采用螺纹连接或者花键联接,连接处为梯形结构,表面为梯形的上底和两个侧边。现有焊接式连接的绝缘接头,绝缘接头内部材料表面会损坏管道表面,尤其是焊接点的凹凸不平之处导致管道表面材料受损,焊接过程中,由于温度过高会导致绝缘材料受损,本发明在套管和套筒内部均设置软胶层,改善了接触面的材质,对管道起到了保护的作用,并且采用机械块之间物理连接,属于一个内部的连接结构,不影响美观;属于冷连接,不会出现高温损坏绝缘材料这一情况,套管表面由嵌合而成的绝缘件覆盖保护,由于热胀冷缩原理,留有一定空腔,能使绝缘效果最佳化,在套筒表面设置的两个绝缘件E,是由于左右两边都设置套管,两边均有挤压作用,绝缘件E切面为折线形状,与套管连接方为水平线,靠近管筒的一边为轴心,顺时针旋转120°为折线的另一边。
所述套筒与套管的连接处设置O型橡胶圈,O型橡胶圈套在连接处的接口位置。O型橡胶圈是具有圆形截面的环行橡胶圈,主要用于机械部件在静态条件下防止液体和气体介质的泄露,型橡胶圈为设计者提供了一种既有效又经济的密封元件,可以解决套筒和套管之间连接出现的缝隙问题,到密封的效果。
所述O型橡胶圈为氢化丁氰橡胶O型橡胶圈或聚四氟乙烯O型橡胶圈。O型橡胶圈为氢化丁氰橡胶O型橡胶圈或聚四氟乙烯O型橡胶圈。氢化丁氰橡胶O型橡胶圈具有良好的抗腐蚀、抗撕裂和抗压缩变形等特性,耐臭氧、耐阳光、耐油性等较好,正常使用温度范围为-40℃~150℃,能够管线实行阴极保护。适用在洗涤机械、汽车发动机系统和新型环制冷系统中,不适合使用于醇类、酯类和芳香族的溶剂中;聚四氟乙烯在航空、电气、化工、机械、仪器仪表、金属表面处理、医药、食品、冶金冶炼、液压等工业中广泛用作耐高低温、耐腐蚀材料,摩擦系数低,防粘涂层等,它已成了不可取代的产品。聚四氟乙烯O型橡胶圈,正常使用温度范围为-25℃~170℃,因为耐高低温、耐腐蚀材料、摩擦系数低,所以将燃气输配管线的各段间、燃气调压站与输配管线间相互绝缘隔离,保护其不受电化学腐蚀, 延长使用寿命。
套管厚度为2cm,套筒厚度为2cm,软胶层厚度为0.5cm,绝缘胶厚度为0.3cm;其中一根套管焊接在套筒的一端,另一根套管焊接在套筒的另一端。
为了使软胶层更好的保护套管和套筒内部、管道表面的材料不受损,所以对其厚度做了要求,在本规格的套管和套筒,软胶厚度为0.5cm、缘胶厚度为0.3cm。最为合适。
胶为触变性绝缘胶或热固性胶绝缘胶。绝缘胶是具有良好电绝缘性能的多组分复合胶。以沥青、天然树脂或合成树脂为主体材料,常温下具有很高粘度,使用时加热以提高流动性,使之便于灌注、浸渍、涂覆。触变性绝缘胶与工件接触后,可立即粘附而形成一层不流动的均匀覆盖层,主要用作小型电器、电工及电子部件的表面护层;热固性胶绝缘胶用于各种管道或作为复合绝缘的粘合剂;浇注胶、密封胶。两种材质都能对套管和套筒表面材料起到保护其不受电化学腐蚀。
本发明与现有技术相比,具有如下的优点和有益效果:
1、本发明一种拆卸的机械式连接带软胶层的绝缘接头,机械块之间物理连接,可以拆卸,避免了因任一部件损坏时,由于不能拆卸的连接关系,导致完好部件也要一并丢弃,造成了极大程度上的浪费;
2、本发明一种拆卸的机械式连接带软胶层的绝缘接头,在套管和套筒内部均设置软胶层,改善了接触面的材质,对管道起到了保护的作用,增加了管道的使用寿命;
3、本发明一种拆卸的机械式连接带软胶层的绝缘接头,在套管和套筒的表面均设置一层绝缘胶,绝缘胶是具有良好电绝缘性能的多组分复合胶。常温下具有很高粘度,使用时加热以提高流动性,使之便于灌注、浸渍、涂覆,方便施工,并且保护了套管和套筒的表面,对其达到了阴极保护。

本发明是一种拆卸的机械式连接带软胶层的绝缘接头,包括两根套管6和一个套筒9,套管6和套筒9均为圆柱形空心管体,套管6空腔直径为10cm,套管6厚度为2cm,套管6长度为40cm;套筒9空腔直径为12cm,套筒9厚度为2cm,套筒2长9为35cm。工作环境温度为50度,连接方式为花键联接,套管6外面为内花键,套筒9内部为外花键;花键形状为圆形,直径10cm,花齿数量为50个,花齿形状为三角形柱体,三角形柱体的三角 形面,底边为0.6cm,高为0.9cm;花齿的长度为5cm。两根套管6和套筒9内部均设置软胶层7,软胶层7改善了接触面的材质对套管6、套筒9、管道起到了保护的作用,在套管6和套筒9的表面均设置一层触变性绝缘胶,,套管表面的由4种规格的绝缘件嵌合覆盖,绝缘件A1的内侧与绝缘件D4的外侧连接,绝缘件B2和绝缘件C3安置在绝缘件A1的内侧与绝缘件D4的外侧连接的空隙内,绝缘件B2嵌在绝缘件A1内侧,绝缘件C3嵌在绝缘件B2和绝缘件D4之间并且嵌合处均有空隙,绝缘件B2、绝缘件C3、绝缘件D4均在绝缘件A1内侧;套筒表面的由4种规格的绝缘件嵌合覆盖,绝缘件A1的内侧与绝缘件D4的外侧连接,两个绝缘件E5外侧分别嵌合在绝缘件A1内侧和绝缘件D4内侧并且嵌合处均有空隙,绝缘件F10外侧和绝缘件5E内侧连接,绝缘件F10内侧覆盖在套筒表面。触变性绝缘胶厚度为0.3cm。绝缘胶是具有良好电绝缘性能的多组分复合胶,能对套管1和套筒2表面材料起到保护其不受电化学腐蚀,延长使用寿命。套筒2与套管1的连接处4设置O型橡胶圈11。
由以上3实施例可知,实施例3保护管道效果最佳。
以上所述的具体实施方式,对本发明的目的、技术方案和有益效果进行了进一步详细说明,所应理解的是,以上所述仅为本发明的具体实施方式而已,并不用于限定本发明的保护范围,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
