Description

一种氯气双孔球阀 技术领域
本发明属于阀体设备，尤其涉及一种氯气双孔球阀。
背景技术
氯气或者液氯具有非常强的腐蚀性，但是很多物质生产中必需的原料。目前常见的氯气阀门均为长颈型，占地面积大，且一旦发生泄漏会因为氯元素的强腐蚀性而难以修复。造成氯元素的大面积泄漏。没有一种氯气阀门可以做到体积小，发生泄漏能立刻断流。
发明内容
1.发明要解决的技术问题
本发明提供一种氯气双孔球阀，体积小，发生泄漏能立刻断流，方便维修。
2.技术方案
为达到上述目的，本发明提供的技术方案为：
一种氯气双孔球阀，由两个阀体构成，第一阀体第二阀体均为球阀，所述的第一阀体位于第一阀座中，第二阀体位于第二阀座中，第一阀座与第二阀座中间设有缓冲间；阀体两端设有连接法兰，阀体上部设有轴承连接阀杆。
更进一步，所述的阀座外部为钢制内部为衬氟塑料。
更进一步，所述的缓冲间内设有滤网。
更进一步，所述的缓冲间设有滤网卡槽。
更进一步，所述的滤网为聚偏氟乙烯网构成。
3.有益效果
球阀具有体积小断流快的特点，两个阀体的设计保证任何一个阀体腐蚀情况下，另一个阀体起到断流作用。整个阀体表面简单平滑，发生泄漏时，断流后可以采用衬氟塑料进行修补，维持短时间内的正常使用，支撑到维修人员赶到，安全性高。结构简单。在两个阀体之间设置缓冲间，防止故障状态下氯气气压大损坏阀体，并具有储存液体的功能，在两阀体之间保留一定空间，滤网的存在是为了防止杂质阻塞阀体的关闭。
附图说明
图1为一种氯气双孔球阀结构示意图；

具体实施方式
为进一步了解本发明的内容，结合附图和实施例对本发明作详细描述。
实施例
一种氯气双孔球阀，由两个阀体构成，第一阀体7第二阀体9均为球阀，所述的第一阀体7位于第一阀座6中，第二阀体9位于第二阀座12中，第一阀座6与第二阀座12中间设有缓冲间8；阀体两端设有连接法兰10、11，阀体上部设有轴承3连接阀杆1、2。
更进一步，所述的阀座外部为钢制内部为衬氟塑料。
更进一步，所述的缓冲间8内设有滤网4。
更进一步，所述的缓冲间8设有滤网卡槽。
