Abstract

本发明公开了一种注油式穿墙止水热力管道，外在外护钢管与内输热载体钢管之间设置有含碳橡胶层，在外套钢管与外护钢管之间设置有油膜，并在外套钢管上设置有注油孔并密封安装有螺栓。本发明采用盘根密封埋入土中寿命可达25年，并且更换简便，耐磨，能够承受管道的径向和轴向载荷。外套钢管强度高，不易变形，同时外护钢管能耐受热力管道的热变形带来的强烈磨擦。设置保温材料和油膜，当内钢管热伸长（冷收缩）时与外套钢管同时运动，避免保温层破坏。钢结构的外露部位均涂有防腐涂料，有效地提高了钢质材料的寿命。

Description

注油式穿墙止水热力管道
技术领域
    本发明涉及供热管道技术领域，具体涉及一种注油式穿墙止水热力管道。 
背景技术
现有穿墙止水套管的外套管采用聚乙烯玻璃外护管，其强度不高，容易老化受损，其固定强度不够，止水效果差，而且与内层热力管道之间的热膨胀系数不同，造成内外层摩擦，加剧外套管老化程度，实用寿命较短。 
发明内容
本发明的目的是针对现有技术中存在的问题和不足，提供一种采用钢结构的注油式穿墙止水热力管道。 
本发明解决其技术问题的技术方案是：一种注油式穿墙止水热力管道，包括内输热载体钢管和外套管，其特征是：所述外套管包括外护钢管和外套钢管，在外护钢管与内输热载体钢管之间设置有含碳橡胶层。 
在外套钢管与外护钢管之间设置有油膜，并在外套钢管上设置有注油孔并密封安装有螺栓。 
所述外护钢管外漏部分的表面为镀锌层，或者设置防腐涂料。 
在所述外套钢管的外侧设置环形凸缘形成盘根。 
有益效果：1、采用盘根密封，一次性压紧；埋入土中，寿命可达25年，并且更换简便。 
2、采用含碳橡胶，止水可靠、耐磨，能够承受管道的径向和轴向载荷。 
3、外套钢管，取代直埋预制保温管的聚乙稀玻璃外护管，钢管强度高，不易变形，有效地被盘根抱紧，而止住水的侵入，同时外护钢管能耐受热力管道的热变形带来的强烈磨擦。 
4、外护钢管和内输热载体的钢管之间，依然有约30mm厚的保温材料，所以整个管线在套管部分仍然具有保温效果，同时当内钢管热伸长（冷收缩）时与外套钢管同时运动，避免保温层破坏。 
5、钢结构的外露部位均涂有防腐涂料，有效地提高了钢质材料的寿命。 
附图说明
图l是本发明的半剖结构示意图。 
图中标号1为内输热载体钢管，2为外护钢管，3为含碳橡胶层，4为外套钢管，5为盘根，6为注油孔密封螺栓。 
具体实施方式
一种注油式穿墙止水热力管道，参见图1，从内向外依次包括内输热载体钢管1、含碳橡胶层3、外护钢管2、外套钢管4和盘根5。在外套钢管4与外护钢管2之间设置有油膜，并在外套钢管4上设置有注油孔并密封安装有螺栓6。外护钢管2的外漏部分表面为镀锌层，钢结构的外漏部分均涂有防腐涂料。
