Abstract

本实用新型涉及控制阀技术领域,具体地说是自力式控制阀,其特征在于,包括:多孔套筒、阀芯、弹性密封、自力式阀座、阀座套、阀杆、复位密封、卡式密封,所述自力式控制阀,在阀芯上设有自力式阀座,所述自力式阀座是改善阀内流体环境,有较强的抗噪音和抗汽蚀能力。

Description

自力式控制阀
技术领域
目前控制阀领域基本没有自力式阀座结构,普遍存在阀体流道设计流量特性差,阀杆运行刚性差,噪音大和容易产生汽蚀。
背景技术
目前控制阀领域基本没有自力式阀座结构,普遍存在阀体流道设计流量特性差,阀杆运行刚性差,噪音大和容易产生汽蚀。
发明内容
本实用新型的目的是克服现有技术的不足,本实用新型提供了自力式控制阀,所述自力式控制阀,其特征在于,包括:多孔套筒(1)、阀芯(2)、弹性密封(3)、自力式阀座(4)、阀座套(5)、阀杆(6)、复位密封(7)、卡式密封(8),所述自力式控制阀,在阀芯(2)上设有自力式阀座(4),所述自力式阀座(4)是改善阀内流体环境,有较强的抗噪音和抗汽蚀能力。
本实用新型的有益效果: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为本实用新型的结构示意图。
其中:多孔套筒(1)、阀芯(2)、弹性密封(3)、自力式阀座(4)、阀座套(5)、阀杆(6)、复位密封(7)、卡式密封(8)。 
具体实施方式]
如图所示,所述自力式控制阀,在阀芯(2)上设有自力式阀座(4),所述自力式阀座(4)是改善阀内流体环境,有较强的抗噪音和抗汽蚀能力。
