Description

耐高温气阀
技术领域
本发明涉及铸造领域的能源重复使用，具体地说是一种耐高温气阀。
背景技术
在铸造领域低压铸造炉是铸造轮毂等铝合金铸件的常规装备，但由于市场上还无使用温度大于900度的气阀，每铸造一次就把炉中的高温气体排空，再注入常温的压缩气体，再对被冷却的炉膛加温，为此不但浪费了能源，增加了生产成本，还由于低压排空速度慢，效率也低。
发明内容
本发明针对上述问题，提供一种耐高温气阀，节能节成本。
按照本发明的技术方案：一种耐高温气阀，包括阀体机构，气动机构、保温机构。
所述阀体机构设置有阀体0，阀体0上设置有进口法兰1、出口法兰7，阀体0中设置有密封塞2，密封塞2中设置有密封杆3，密封杆3上设置有连轴器4，所述阀体0使用耐热不锈钢，用耐热覆膜砂模重力浇铸，密封塞2使用高温陶瓷制成。
所述气动机构设置有气缸5，气缸5中设置有活塞6。
所述保温机构设置有保温套8；所述保温套8采用莫来石多晶纤维。
本发明的技术效果在于；采用耐热不锈钢制成的阀体0、高温陶瓷制成密封塞2工作温度可达950C度，满足炉内气体800C度循环使用的要求，采用气动机构控制耐高温气阀，结构简单控制方便，使低压铸造炉提高工效，节能节成本。
附图说明
图1是本发明的结构示意图。
具体实施方式
下面结合附图对本发明的中的具体实施方式作进一步说明。
图1中，包括阀体0、进口法兰1、密封塞2、密封杆3、连轴器4、气缸5、活塞6、出口法兰7、保温套8等。
如图1所示，本发明是一种耐高温气阀，包括阀体机构，气动机构、保温机构。
所述阀体机构包括阀体0、进口法兰1、出口法兰7、密封塞2、密封杆3、连轴器4，所述进口法兰1、出口法兰7设置于阀体0上，密封塞2设置于阀体0中，密封杆3与密封塞2连接，连轴器4与密封杆3连接，所述阀体0使用耐热不锈钢，用耐热覆膜砂模重力浇铸，密封塞2使用高温陶瓷制成。
所述气动机构包括气缸5、活塞6等，活塞6设置于气缸5中，活塞杆与连轴器4连接。
所述保温机构的保温套8设置于阀体0外壁，所述保温套8采用莫来石多晶纤维。
本发明使用时用电磁阀控制气缸就能使耐高温气阀开闭，结构简单控制方便，用于低压铸造炉上提高工效，节能节成本。
