Description
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。
