Description

一种新型高性能自力式控制阀
技术领域
本发明涉及控制阀技术领域，尤其是一种新型高性能自力式控制阀。
背景技术
目前控制阀领域设计基本没有应用自身压力进行控制的设计项目。
发明内容
   为了克服现有技术的不足，本发明提供了一种新型高性能自力式控制阀，所述一种新型高性能自力式控制阀，其特征在于，包括：三法兰阀体1、压力平衡体2、施压螺丝3、弹簧压缩量指示牌4、填料5、筒式支架6、弹簧7、膜头8、取压短管9、冷却罐10、给压管11，所述一种新型高性能自力式控制阀，在三法兰阀体1上设有取压短管9，其取压短管9是为了给膜头8的压力，改善阀内流体环境，有较强的抗噪音和抗汽蚀能力。
本发明的有益效果：1.改善阀内流体环境，防气蚀、防空化。2.保护阀体及阀内件，克服来自流体的较大的不平衡力，承受大的压差。3.阀室内的流道更简明，阻力小，也解决了抗噪音和抗汽蚀能力的问题。
附图说明]
图1为本发明的结构示意图。
其中：三法兰阀体1、压力平衡体2、施压螺丝3、弹簧压缩量指示牌4、填料5、筒式支架6、弹簧7、膜头8、取压短管9、冷却罐10、给压管11。 
具体实施方式]
如图所示，所述一种新型高性能自力式控制阀，在三法兰阀体1上设有取压短管9，其取压短管9是为了给膜头8的压力，改善阀内流体环境，有较强的抗噪音和抗汽蚀能力。
