进口高压蝶阀【进口高压蝶阀】详细说明:阀门的蝶板在启闭过程中,实现了蝶板密封圈与阀座密封面之间的无滑动磨擦·卡挤,密封面上的压力角大于磨擦角,采用了“径向动平衡密封系”设计,是蝶板开启阻力极低。启闭过程中蝶板密封面沿360°圆周各点可以瞬间快速完成,逐点接触和逐点脱离。开启密封即可分离,快速准确实现关闭接触自动相吻合的密封动作。调节型多层次·全金属硬密封蝶阀由于密封面采用多重密封和整体全金属密封,经过高精度机械加工成椭圆形截面密封环,它与阀座金属密封面组成密封副。这种密封结构,在高压工况下不产生塑性变形,在高温或低温工况下,不存在冲压应力、焊接应力、弹性退火或咬坏脆裂现象,***了传统蝶阀密封结构不合理引起泄漏的弊病、大大提高了阀门密封可靠性。Duringtheopeningandclosingprocessofthebutterflyplateofthevalve,thenon-slidingfrictionandjammingbetweenthebutterflyplatesealringandthesealingsurfaceofthevalveseatarerealized.Thepressureangleonthesealingsurfaceislargerthanthefrictionangle.Thedesignof"radialdynamicbalancesealsystem"isadopted,whichmakestheopeningresistanceofthebutterflyplateverylow.Duringtheopeningandclosingprocess,thesealingsurfaceofbutterflyplatealong360degreecircumferencecanbecompletedinstantaneouslyandquickly,pointbypointcontactandpointbypointdetachment.Thesealcanbeseparatedbyopeningtheseal,whichcanquicklyandaccuratelyrealizethesealingactionofautomaticcoincidenceoftheclosedcontact.Adjustablemulti-levelall-metalhard-sealedbutterflyvalvesaremachinedintoellipticalcross-sectionsealingringswithhighprecisionduetomultiplesealsandoverallall-metalsealsonthesealingsurface,whichformasealingpairwiththemetalseatingsurfaceofthevalveseat.Thesealingstructuredoesnotproduceplasticdeformationunderhighpressurecondition,anddoesnotexiststampingstress,weldingstress,elasticannealingorbitebrittlecrackingunderhighorlowtemperaturecondition.Itcompletelysolvesthedefectofleakagecausedbyunreasonabletraditionalbutterflyvalvesealingstructureandgreatlyimprovesthereliabilityofvalvesealing.【进口高压蝶阀】使用范围:本阀适用于高、中、低压,高温、低温的管路中作闭路密封装置、节流装置和调节装置。广泛适用于石油、化工、冶金、矿山、电力、能源、交通、农田、水力、环保、建筑、医药、生物等行业。特别适用密封性要求较严格的工况,如煤气管道上,也适用水、蒸气、油品、空气、尘气、硝酸等腐蚀性介质。【进口高压蝶阀】特点:1、采用的是三偏心结构,密闭性能可靠。2、确保开启时蝶板不接触密封座,消除了密封座不均匀负载,延长了使用寿命。3、确保可靠的密封性能,具有耐高温、耐磨损、耐腐蚀等优点。【进口高压蝶阀】特性:1、本阀采用三偏心密封结构,阀座与蝶板几乎无磨损,具有越观越紧的密封功能。2、密封圈选用不锈钢制作,具有金属硬密封和弹性密封的双重优点,无论在低温和高温的情况下,均具有优良的密封性能,具有耐腐蚀,使用寿命长等特点。3、碟板密封面采用堆焊钴基硬质合金,密封面耐磨损,使用寿命长.4、大规格蝶板采用绗架结构,强度高,过流面积大,流阻小。5、本阀具有双向密封功能,安装时不受介质流向的限制,也不受空间位置的影响,可在任何方向安装。)
