Description

带有双密封面阀座的调节阀
技术领域:
本实用新型阀门技术领域,具体涉及一种带有双密封面阀座的调节阀。
背景技术:
目前,普通的调节阀其阀座均采用薄壁结构,普通螺纹旋入精小型阀体,必须使用特殊的夹具装、卸,而且刚性差易变形,基本无法长期使用,特别是长期使用后根本无法拆卸,必须更换整机,无法实现高可靠性自控要求,与现代自控理想的矛盾日益突显。
实用新型内容:
本实用新型针对现有调节阀的控制不稳定、使用寿命不长及维护麻烦等问题,提供一种适用于各种要求密封严密、调节可靠性高的自控工作场合的调节阀。
技术方案:一种带有双密封面阀座的调节阀,包括阀体,阀盖,阀杆和阀芯,其中,与阀芯配合的进口上套装有一个双密封面阀座,所述阀芯密封面与双密封面阀座密封面配合密封,在阀体上部内侧套装有一个环形压套,环形压套侧壁设置有窗口,所述阀盖与环形压套压合在一起。
所述阀盖上端与阀杆之间设置环形腔,环形腔内套装有填料垫,填料垫下侧的阀杆上套装有填料弹簧,环形腔上侧端口套装有填料压钉,填料压钉的上侧套装固定有填料压板,环形腔内填充有填料。
有益效果:本实用新型的调节阀采用了高强度橄榄形GLOBE阀体和高强度锻件阀盖,配用上部顶导向式阀芯结构,阀杆与阀芯采用一体化设计,保证了调节阀具体高可靠的强度。阀座采用高强度无螺纹结构,直接放入阀体中腔内,用带窗口压套固定阀座,借用阀盖螺柱的力压紧阀座,增强了阀座的强度,提高了阀门的防泄漏等级,阀座采用双密封面设计,当长期使用后,出现泄漏,只需翻转阀座即可重新使用,大大提高了调节阀的使用寿命,因阀座采用无螺纹连接,故无需采用特殊的夹具装、卸,使调节阀的维护更加方便、可靠。本实用新型的调节阀可配用各种高可靠性的气、电动执行机构,彻底解决了目前调节阀的控制不稳定、使用寿命不长及维护麻烦等问题,并真正满足了高可靠性。
附图说明:
图1是本实用新型调节阀的剖面结构示意图。
图中标号1为阀体,2为密封圈,3为双密封面阀座,4为阀杆,5为环形压套,6为阀盖密封圈,7为阀盖,8为双头螺柱,9为平垫片,10为螺母,11为填料弹簧,12为填料垫,13为填料,14为填料压钉,15为填料压板,16为阀芯。
具体实施方式:
实施例1:参见图1,一种带有双密封面阀座的调节阀,包括阀体1,阀体1上部固定有高强度锻件阀盖7,以及阀杆4和阀芯16等部件。其中,与阀芯16配合的进口(安装孔)上套装有一个高强度的双密封面阀座3,采用无螺纹式安装。所述阀芯16密封面与双密封面阀座3密封面配合密封。在阀体1上部内侧套装有一个环形压套5,环形压套5侧壁设置有窗口,所述阀盖7与环形压套5压合在一起。另外,在阀盖7上端与阀杆4之间设置环形腔,环形腔内套装有填料垫12,填料垫12下侧的阀杆4上套装有填料弹簧11,环形腔上侧端口套装有填料压钉14,填料压钉14的上侧套装固定有填料压板15,环形腔内填充有填料13。阀杆4的上端通过阀体和阀盖连接处的导向套伸出阀盖外,连接在执行机构输出轴上,并且随执行机构的驱动而上、下移动,从而带动阀芯的上、下移动,以改变阀芯与双密封面阀座之间的节流面积大小,从而调节经过阀流出的介质流量。
当流体介质经过阀体1的入口流入阀体内部,随阀芯16部件的上移,流体介质通过阀座处的节流口流入阀体的上腔,由阀体的出口流入流体管道。
