Kev faib tawm thiab cov yam ntxwv ntawm Pneumatic Pob Valve

Pneumatic pob li qub tau muab faib ua O-hom pob li qub thiab V-hom pob li qub. O-hom pob valve txais cov qauv ntab, pob core yog precision casting, nyuaj chromium plating kev kho mob ntawm qhov chaw, lub rooj zaum valve txais cov khoom siv PTFE reinforced, khiav lub qhov ncauj thiab cov kav dej txoj kab uas hla yog tib yam, muaj peev xwm txaus, txaus ua haujlwm me me, tsis muaj dej xau thaum kaw. Nws feem ntau yog siv los ua lub pob valve, tshwj xeeb tshaj yog rau siab viscosity, V-hom pob valve nrog cov qauv ruaj khov. Lub V-shaped notch yog teem rau ntawm tus kheej kheej kheej kom paub shearing ntawm fiber ntau thiab granular media.

根据工艺设备不同可选用气动或电动执行机构,分别组成气动球阀和电动球阀,其中气动球阀如要实现比例调节须配阀门定位器,电动球阀如要实现比例调节须选电子式电动执行机构或配伺服放大器等.

Pneumatic lossis hluav taws xob actuators tuaj yeem xaiv raws li cov txheej txheem sib txawv, thiab pneumatic pob li qub thiab hluav taws xob pob li qub yog tsim raws li. Yog hais tias pneumatic pob li qub yuav tsum ua kom tau raws li kev cai, lawv yuav tsum tau nruab nrog lub valve positioners, thiab yog hais tias lub pob hluav taws xob yuav tsum tau ua raws li kev cai, lawv yuav tsum tau nruab nrog hluav taws xob hluav taws xob actuators lossis servo amplifiers.

从材质上,可以分为:碳钢球阀,不锈钢304球阀,316球阀和铜球阀

Los ntawm cov khoom siv, nws tuaj yeem muab faib ua: carbon steel pob valve, stainless hlau 304 pob valve, 316 pob valve thiab tooj liab pob valve.

按压力,可以分为:高压球阀和低压球阀

Lub siab tuaj yeem muab faib ua: siab siab pob valve thiab qis siab pob valve.

高压气动球阀:主要应用在石油,日然气,液压油,工程机械等行业

Siab siab pneumatic pob li qub: feem ntau yog siv rau hauv roj av, natural gas, hydraulic roj, siv machinery thiab lwm yam lag luam

低压气动球阀:主要应用在介质为水等腐蚀性管路上!刀型闸阀产品使用中注意事项及其型号:刀型闸阀的启闭件是闸板,闸板的运动方向与流体方向相垂直,手动刀型闸阀只能作全开和全关,不能作调节和节流.闸板有2个密封面,最常用的模式闸板阀的2个密封面形成楔形,楔形角随阀门参数而异,通常为50,楔式刀型闸阀的闸板可以做成一个整体,叫做刚性闸板;也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板刀型闸阀关闭时,密封面可以只依靠介质压力来密封,即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封.大部分刀型闸阀是采用强制密封的,即阀门关闭时,要依靠外力强行将闸板压向阀座,以保证密封面的密封性本类阀门在管道中一般应当水平安装.

Tsis tshua muaj siab Pneumatic Pob Valve: Feem ntau yog siv nyob rau hauv corrosive pipelines xws li dej. Cov ntawv ceeb toom thiab cov qauv hauv kev siv cov khoom siv riam rooj vag valve: qhov qhib thiab kaw qhov chaw ntawm riam rooj vag valve yog lub rooj vag, cov kev taw qhia ntawm lub rooj vag phaj yog perpendicular mus rau cov kev taw qhia ntawm cov kua, thiab phau ntawv riam rooj vag valve tsuas yog qhib thiab kaw. , thiab tsis tuaj yeem hloov kho thiab throttled. Lub rooj vag muaj ob qhov chaw sealing. Ob qhov chaw sib khi ntawm qhov feem ntau siv hom rooj vag li qub tsim cov npoo-puab thiab cov npoo-zoo li lub kaum sab xis, uas sib txawv nrog lub valve tsis. Feem ntau, cov npoo-zoo li lub rooj vag li qub tuaj yeem ua rau tag nrho, hu ua cov rooj vag nruj. Lawv kuj tuaj yeem ua rau hauv cov rooj vag uas tuaj yeem tsim me ntsis deformation los txhim kho lawv cov kev ua haujlwm thiab ua rau lub kaum sab xis sealing. Deviation nyob rau hauv tus txheej txheem ntawm kev ua, hom ntawm lub rooj vag no yog hu ua elastic rooj vag riam rooj vag valve, thaum kaw, lub sealing nto tsuas yog cia siab rau nruab nrab siab rau foob, uas yog, cia siab rau lub nruab nrab siab los nias lub sealing nto ntawm lub sealing nto. rooj vag mus rau sab nraud ntawm lub rooj zaum valve kom paub meej qhov sealing nto sealing, uas yog tus kheej sealing. Feem ntau cov riam rooj vag li qub raug yuam kom kaw, uas yog, thaum lub valve kaw, lub rooj vag yuav tsum raug yuam mus rau lub rooj zaum los ntawm kev quab yuam sab nraud kom ntseeg tau tias lub sealing nto ntawm hom valve hauv cov raj xa dej feem ntau yuav tsum tau nruab kab rov tav.
