Description

新型飞机水车污水罐排气帽
技术领域
本发明涉及一种新型飞机水车污水罐排气帽。 
背景技术
飞机水车污水罐排气帽安装在污水罐的顶部,用于污水罐与外界相连,保持污水罐内的正常压力。传统的排气帽因其密封性能较差,当污水罐装水较多时,污水容易通过排气帽溢到外面,容易对环境造成二次污染。 
发明内容
为解决上述技术问题,本实用新型提供了一种新型飞机水车污水罐排气帽。 
解决上述技术问题的技术方案是:新型飞机水车污水罐排气帽,包括排气帽阀座和排气帽防雨盖;排气帽阀座焊接在污水罐体上,包括阀芯,隔栅,橡胶垫一及橡胶垫二;排气帽阀座顶部设有六个通气孔。 
本实用新型的有益效果是:结构紧凑、操作使用方便,且可有效的防止污水外溢,减少了污水的二次污染。 
附图说明
图1为新型飞机水车污水罐排气帽的结构图。 
图2为新型飞机水车污水罐排气帽防雨盖的俯视图。 
具体实施方式
下面结合附图和具体实施方式对本实用新型进行进一步详细说明。如图1所示,新型飞机水车污水罐排气帽,包括排气帽阀座1和排 气帽防雨盖2;排气帽阀座1焊接在污水罐体上,包括阀芯3,隔栅4,橡胶垫一5及橡胶垫二6; 
如图2所示,;排气帽座1顶部设有六个通气孔7。 
上述新型飞机水车污水罐排气帽的工作原理是:水车行驶时,罐内污水液面浪起,排气帽阀芯3挡住污水防止其进入真空管内,当真空管从罐内向外界抽吸空气时,罐内气体将排气帽阀芯3推开,使抽真空可以顺利进行。罐内具有一定真空度时,橡胶垫一5被吸紧在阀座上,形成密封,使真空抽吸能够顺利进行。罐内不抽真空,污水从飞机上依靠重力流入罐内时,流入污水将罐内气体向外挤,此时罐内气体推开阀芯3及橡胶垫一5排出到外面,使污水可以顺利流进罐内。 
本发明不仅结构紧凑、操作使用方便,且可有效的防止污水外溢,减少了污水的二次污染。
