Description

一种铁路罐车卸油装置 技术领域
一种铁路罐车卸油装置，属于铁路货车技术领域的一种卸油装置。
背景技术
目前国内轻油类罐车装卸货过程中主要存在问题有：
1.当从上部向铁路罐车灌装轻油类油品时，由于鹤管尺寸较大，操作不方便，无法将鹤管插到油罐车底部，导致油品的损耗和静电。
2.在夏天高温环境时，执行上部卸油作业时，极易在鹤管的高点产生气阻，降低卸油效率，延长作业时间，加大油品蒸发损耗。严重时油路会因气阻而断流，导致卸货作业中断。
3.随着铁路行业高速、重载的不断推进，面对现有装卸设施固定，短期内无法实施改造的事实，大载重铁路罐车装卸不方便的情况日益突显。突破现有的装卸方式，研发一种新型的装卸装置成为一种可能。
4.针对矿区油类物资的装卸及运输，面临卸载油料的随时性和配备专业的装、卸货设备的高成本，研发新型的装、卸装置成为一种必然。
发明内容
本发明要解决的问题是针对以上不足而提供一种能满足底部装、卸油的作业方式的卸油装置。其技术方案如下：
一种铁路罐车卸油装置，包括排油管和卸油阀，其关键技术在于卸油阀包括中部卸油阀和端部卸油阀，排油管中部通过T型三通管与中部卸油阀连接，排油管两端设置端部卸油阀，中部卸油阀和端部卸油阀构成“T”型结构。
在排油管两端安装排油口连接装置，排油口连接装置包括法兰连接盘和连接螺纹。
在排油口连接装置上安装防护罩，防护罩内部设置内螺纹与排油口连接螺纹相匹配。
所述排油管通过固定装置固定，包括连接座、阀门安装座，其中连接座 将固定装置与车体相连，阀门安装座下部通过紧固件固定排油管及端部卸油阀，连接座与阀门安装座垂向依次设置软木和调整垫。
与现有技术相比，本发明具有以下有益效果：
1、一种铁路罐车卸油装置，设置中部、端部两级卸油阀，实现两级开闭保护的同时，实现漏泄双重防护，提高车辆行车安全系数；
2、实现两级开闭保护，不会造成油品的损耗和静电，操作方便；也不会产生气阻，卸油效率提高，减少作业时间，最大限度降低油品蒸发损耗。
3、排油管固定装置采用软木及金属安装座的组合方式，垂向、横向具有一定的可调性，其中垂向通过调整垫进行调整，横向通过阀门安装座上预设的长圆孔进行调整；软木的使用，降低组装难度的同时，可以改善空、重车状态下，排油管的受力状况，避免焊缝失效或密封失效进而出现介质漏泄的情况。
4、端部防护罩内螺纹与排油口螺纹相匹配，在防止异物进入排油口的同时，有效保护排油口螺纹免受损坏，以免导致连接失效。
5、卸油装置的排油口采用法兰、螺纹两种接口形式，易于拆卸、便于维护，降低对用户接口设施要求。
6、在法兰面设置密封圈放置环槽，防止密封圈窜动的同时，提升密封效果。
7、“T”型三通管结构，将现有技术的相关线焊缝转换为环形焊缝，改善受力状况，提升焊接质量，降低介质漏泄风险。
