Description

一种遥控阀的液压控制管贯通件 技术领域
本发明涉及管道密封技术领域，具体涉及一种遥控阀的液压控制管贯通件。
背景技术
传统的成品油及原油船货油舱遥控阀液压控制管在甲板面所使用的油水密贯通件的一般设计型式是采用不锈钢套筒作为贯通件的本体与船体甲板焊接，控制管穿过套筒后在套筒与控制管之间填充缠绕型特氟龙盘根进行密封，最后在贯通件的本体顶部采用压紧件进行压紧。
在安装时，特氟龙盘根需要一圈一圈地缠绕在控制管的外壁，在控制管插入到贯通本体内时，盘根卡设在控制管的外壁与贯通本体之间，以最常用的8*8mm盘根计算，如果贯通本体高100mm，则需要缠绕的圈数就将近12层之多。由于每一层盘根之间很难杜绝缝隙的存在，且由于缠绕型特氟龙盘根本身也是由缠绕编织而成，其本身也会存在间隙。因此传统的贯通件所采用的密封型式极容易导致泄漏，即甲板面的雨水或者海水容易漏到货舱，导致货品的污染。

具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
在本发明的描述中，需要理解的是，术语“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
在本发明的描述中，除非另有明确的规定和限定，术语“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两 个部件内部的连通或两个部件的相互作用关系。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接抵接，也可以包括第一和第二特征不是直接抵接而是通过它们之间的另外的特征抵接。而且，第一特征在第二特征之“上”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征之“下”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
如图1所示，本发明的实施例提供一种遥控阀的液压控制管贯通件，包括：贯通本体1，安装于固定板2上，贯通本体1沿其轴向具有贯通孔11；封堵件，封堵件包括第一封堵件31和第二封堵件32，分别用于封堵贯通孔11的两个开口端，且第一封堵件31和第二封堵件32上分别开设有与贯通孔11同轴的第一安装孔；控制管4，控制管4与第一安装孔插接配合；密封件5，密封件5采用耐油橡胶材料制成，其套设于控制管4的外壁，密封件5包括与第一封堵件31抵接的第一平垫片51、与第二封堵件32抵接的第二平垫片52，以及位于第一平垫片51和第二平垫片52之间且与第一平垫片51和/或第二平垫片52抵接的至少一个“V”型垫片53；封堵件挤压密封件5时，“V”型垫片53发生变形，以使“V”型垫片53分别与控制管4的外壁和贯通孔11的孔壁抵紧。本实施例中，第一平垫片51、第二平垫片52及“V”型垫片53均为套设在控制管4外部的环形结构的垫片，在封堵件挤压密封件5时，“V”型垫片53受到挤压而发生变形，从而使贯通本体1的贯通孔11与控制管4之间实现密封，而第一平垫片51和第二平垫片52主要对控制管4起承托、保护作用，以及调节“V”型垫片53的压缩量的作用。与现有技术相比，本实施例的遥控阀的液压控制管贯通件的密封 效果非常好。
本实施例中，密封件5采用可挤压变形的耐油橡胶材料制成，其中，耐油橡胶包括但不限于硅橡胶、丁腈橡胶、氟橡胶、氯丁橡胶、三元乙丙橡胶等，具有良好的耐油、耐酸碱、耐寒热、耐老化等性能。
本实施例中，各部件尺寸及“V”型垫片53的数量及规格根据液压控制管的规格及固定板2的厚度等因素进行确定及调整。
在本发明的其中一个实施例中，参照图1，“V”型垫片53与第一平垫片51抵接，“V”型垫片53的开口朝向第一平垫片51，“V”型垫片53与第二平垫片52之间填充有盘根6，封堵件挤压密封件5时，挤压作用力通过第一平垫片51传递至“V”型垫片53，使“V”型垫片53发生变形，而使控制管4靠近第一封堵件31的一端与贯通孔11之间实现密封，而其中的盘根6对“V”型垫片53具有支撑作用；其中，“V”型垫片53的数量可以是一个，也可以是两个甚至更多个同轴堆叠。
在本发明的另一个实施例中，参照图1，“V”型垫片53与第二平垫片52抵接，“V”型垫片53的开口朝向第二平垫片52，“V”型垫片53与第一平垫片51之间填充有盘根6，其中，盘根6填充在“V”型垫片53与第一平垫片51之间，且在挤压作用力下，盘根6可沿控制管4的长度方向移动；封堵件挤压密封件5时，挤压作用力通过第一平垫片51依次传递至盘根6及“V”型垫片53，“V”型垫片53受到挤压发生变形，而使控制管4靠近第二封堵件32的一端与贯通孔11之间实现密封，而其中的盘根6对“V”型垫片53具有支撑作用；其中，“V”型垫片53的数量可以是一个，也可以是两个甚至更多个同轴堆叠。
在本发明的又一个实施例中，如图1所示，“V”型垫片53包括第一“V”型垫片531和第二“V”型垫片532，第一“V”型垫片与第一平垫片51抵接，第一“V” 型垫片531的开口朝向第一平垫片51，第二“V”型垫片53与第二平垫片52抵接，第二“V”型垫片532的开口朝向第二平垫片52，第一“V”型垫片531和第二“V”型垫片532之间填充有盘根6，其中，第一“V”型垫片531的数量可以是一个，也可以是两个甚至更多个同轴堆叠；第二“V”型垫片532的数量可以是一个，也可以是两个甚至更多个同轴堆叠。盘根6填充在第一“V”型垫片531和第二“V”型垫片532之间，且在挤压作用力下，盘根6可沿控制管4的长度方向移动；封堵件挤压密封件5时，挤压作用力通过第一平垫片51依次传递至第一“V”型垫片531、盘根6及第二“V”型垫片532，第一“V”型垫片531和第二“V”型垫片532受到挤压发生变形，而使控制管4靠近第一封堵件31及第二封堵件32的两端分别与贯通孔11之间实现密封。
本实施例中，如图1所示，第一“V”型垫片531和第二“V”型垫片532的数量分别为两个。
其中，盘根6指的是特氟龙盘根，其通过缠绕方式环设在控制管4的外壁。
本实施例中的盘根6也可以采用平垫片替代。
在本发明的一个优选的实施例中，“V”型垫片53为若干个，沿贯通孔11的轴向，若干“V”型垫片53同轴堆叠至一端与第一平垫片51抵接，另一端与第二平垫片52抵接，若干“V”型垫片53的开口均朝向第一平垫片51或第二平垫片52。本实施例中，第一平垫片51和第二平垫片52之间没有设置盘根6，第一平垫片51和第二平垫片52之间被同轴堆叠的“V”型垫片53填充满，封堵件挤压密封件5时，挤压作用力通过第一平垫片51依次传递至“V”型垫片53，“V”型垫片53受到挤压发生变形，而使控制管4与贯通孔11之间实现全密封，采用同轴堆叠的“V”型垫片53，可以增强控制管4与贯通孔11之间的密封效果。
于本实施例中，“V”型垫片53包括倾斜方向相反的第一斜垫片和第二斜垫 片，第一斜垫片和第二斜垫片分别与控制管4的外壁、贯通孔11的孔壁面接触，相对于线接触，本实施例的“V”型垫片53采用面接触可以进一步增强控制管4与贯通孔11之间的密封效果。
贯通本体1的两个开口端分别为第一端和第二端，第一封堵件31与第一端可拆卸连接，以方便密封件5和/或盘根6的安装。第二封堵件32固定设置在第二端，具体的固定形式可以为焊接。
具体地，第一封堵件31包括锁紧螺塞311，锁紧螺塞311包括螺纹段3111和非螺纹段3112，第一安装孔开设在锁紧螺塞311的轴心处，贯通孔11内设置有与螺纹段3111的外螺纹相配合的内螺纹，螺纹段3旋入所述贯通孔11内以使“V”型垫片53发生变形。锁紧螺塞311旋入至贯通孔11内，且旋入到位之后，锁紧螺塞311对第一平垫片51产生挤压作用力，间接挤压“V”型垫片53，使“V”型垫片53发生变形。
进一步地，第一封堵件31还包括锁紧盖板312，锁紧盖板312的轴心处开设有与非螺纹段3112插接配合的第二安装孔，锁紧盖板312通过紧固件313与环设在第一端的外周的连接板12可拆卸连接，其中，第二安装孔主要对非螺纹段3112起限位作用，以防止锁紧螺塞311松动，以确保贯通件具有持续密封的效果。
非螺纹段3112的横截面为非圆形结构，例如正多边形等，以方便旋紧锁紧螺塞311。
紧固件313为若干均匀环设的紧固螺丝，对应紧固螺丝，锁紧盖板312与连接板12上分别开设有螺纹孔，锁紧盖板312通过紧固螺丝与连接板12可拆卸连接。
贯通本体1贯穿固定板2，且与固定板2双面焊接。其中，贯通本体1穿过 固定板2上的固定孔之后，固定板2的两侧分别与贯通本体1焊接，以提高遥控阀的液压控制管贯通件的结构稳定性及其与固定板2之间的密封效果。
本实施例中的遥控阀的液压控制管贯通件适用于成品油及原油船上，可作为货油舱内的甲板处的油水密通舱件。其中，固定板2即为甲板。
本实施例中，贯通本体1、锁紧螺塞311、锁紧盖板312及紧固件313均为不锈钢材质。
本实施例的遥控阀的液压控制管贯通件的装配流程为：先将贯通本体1穿到上甲板开孔内并双面焊接，然后将控制管4从贯通本体4内穿过；管路安装后先在贯通本体1跟控制管4之间套入一个平垫片，再套入所需数量的“V”形垫片，然后在“V”形垫片的顶部再套设一个平垫片；垫片安装完毕之后，贯通本体1顶部安装压紧螺塞311及锁紧盖板312。
本发明中，遥控阀的液压控制管贯通件相对于现有技术的优点主要表现在以下几个方面：
该遥控阀的液压控制管贯通件采用耐油橡胶制成的平垫片和“V”形垫片，相对于传统的贯通件仅仅采用的特氟龙盘根的缠绕式安装型式，不仅降低了密封材料的费用，而且极大地降低了安装难度、节省了安装时间；
该遥控阀的液压控制管贯通件采用挤压“V”形耐油橡胶垫片实现密封效果，其相对于传统的贯通件采用缠绕型氟龙盘根的缠绕式安装，在密封效果上得到极大的提高，这不仅提高了船舶运营安全性；同时也极大地提高了船厂的报验通过率，避免不必要的返工；
该遥控阀的液压控制管贯通件所采用的耐油橡胶垫片，在后期拆卸检查后，平垫片和“V”型垫片还可以继续使用；但传统贯通所采用的特氟龙盘根，只要拆下来基本上就需要更换新的盘根才能确保密封的效果。
综上所述，本发明的遥控阀的液压控制管贯通件不仅可以降低船厂的安装难度、提高船厂安装及报验的一次性通过率，这可以大大的节省船厂人工成本；同时，遥控阀的液压控制管贯通件中的密封件检修后可继续使用，可以降低船厂及船东的在元件更换方面的费用。
