Description

弹性同心高温金属密封球阀
技术领域
本实用新型涉及一种阀门，尤其是一种弹性同心高温金属密封球阀。
背景技术
球阀是阀门中的主要阀类，主要包括阀座、阀体、阀杆和球体。传统球阀，包括软密封球阀及硬密封球阀，受其密封材料及构造所限制，局限其更广的使用范围。具体的说存在如下缺点：
1、使用温度难以跨越450℃。高温状况下，阀座与阀体之间的密封泄露隐患。
2、耐磨性能差，不适合用于带颗粒性与固物类介质的管线。
3、高温及高压状况下，阀杆填料的密封泄露隐患；阀体连接处的静密封泄露隐患。
以上几点，传统球阀在高温、高压及磨损性(带颗粒性与固物类介质)的管道上难以解决及经常碰到的问题。
发明内容
本实用新型的目的为提供一种能在高温、高压及磨损性介质中使用，密封性能好的弹性同心高温金属密封球阀。
实现上述发明目的的技术方案如下：
弹性同心高温金属密封球阀，包括阀体、支撑阀座、球体和阀杆，阀体分为阀本体和连接体，阀本体与连接体之间设有三角锥形密封垫，阀杆与阀本体之间设有复合填料，阀杆上端设有支架平台与阀体相连，所述连接体内端面形成阀座。
所述支撑阀座与阀本体之间设有弹簧。
所述阀杆下部与阀本体之间设有止推轴承。
所述支架平台中部开有凹槽，凹槽内设有阀杆导向套，阀杆导向套套接于阀杆上端。
本实用新型阀座与连接体一体化，杜绝了阀座与阀体之间的泄露。组合型的复合填料实现了阀杆与阀体连接处的可靠密封。锥型的阀体密封垫实现了阀体连接处的可靠密封，尤其是在高温高压的高跨度变化状况下，在一定范围内压力、温度越高密封效果越好。阀杆与止推轴承及阀杆导向套的组合，即解决了阀杆在高压状况下意外脱落，又实现了阀杆的同心旋转不至于偏离而损伤复合填料。弹簧的设计实现了补偿密封及吸收热胀现象。
附图说明
图1为本实用新型内部结构示意图
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步说明。
如图1所示，
弹性同心高温金属密封球阀，包括阀体、支撑阀座、阀座、球体和阀杆，阀体分为阀本体1与连接体2之间设有三角锥形密封垫8，阀杆7与阀本体1之间设有复合填料10，所述连接体2内端面形成阀座5，支撑阀座4与阀本体1之间设有弹簧3，球体6与支撑阀座4和阀座相接处，阀杆下部与阀体之间设有止推轴承9，所述阀杆7上端设有支架平台12与阀本体1相连，支架平台12中部开有凹槽，凹槽内设有阀杆导向套11，阀杆导向套11套接于阀杆上端。
