Hauv kev tswj cov kua dej thoob plaws kev lag luam, covVertical Lift Check Valvestands raws li ib tug tseem ceeb tivthaiv engineered los xyuas kom meej unidirectional media flow thiab tshem tawm cov backflow txaus ntshai. Lub valve no ua haujlwm ntawm qhov tseeb -tsav mechanism: thaum cov xov xwm ntws mus rau pem hauv ntej, cov kua thrust nqa lub valve disc raws qhov ntsug nruab nrab ntawm lub valve lub cev, ua kom txoj kev du. Thaum ntws nres lossis thim rov qab, lub disc nrawm nrawm hauv qab nws lub ntiajteb txawj nqus thiab rov qab kua dej siab- feem ntau ruaj khov los ntawm lub tes tsho qhia kom raug kaw. Tsis zoo li lub viav vias kos li qub, nws txoj kev nqa nqa ntsug txo qis qis qis thiab ua kom muaj kev ruaj ntseg zoo tshaj plaws, ua rau nws tseem ceeb rau qhov siab -xav tau kev lag luam ib puag ncig.

Khoom Taw Qhia

Vertical Lift Check Valve yog tus kheej - actuated, ib - txoj kev valve tsim rau ntsug lossis kab rov tav installation (nrog caij nplooj ntoos hlav- loaded variants). Nws cov qauv compact nyob rau ntawm ib qho kev txav mus los - lub valve disc - txo cov ntsiab lus tsis ua hauj lwm thiab ua kom yooj yim txij nkawm. Cov kev qhia tshwj xeeb tseem ceeb ua tau raws li cov qauv kev lag luam thoob ntiaj teb, ua kom muaj kev sib raug zoo nrog ntau lub tshuab:

Qhov Loj: NPS 1/4 "~ 20" (DN15 ~ 500), txuas mus rau DN 1200 rau cov ntawv loj -.

Kev ntsuas siab: Chav Kawm 150 ~ 2500, PN 10 ~ 420, thiab mus txog PN 320 rau siab -siab tshuab.

Kub Tolerance: -196℃~ +550 degree, haum rau cryogenic thiab high-temperature media.

Khoom siv: valve lub cev xaiv muaj xws li carbon steel, stainless hlau (CF8 / CF8M), hlau alloy, thiab fluorine -lined variants (PTFE / PFA) rau corrosion kuj.

Cov qauv tsim: Ua raws li API 6D, ASME B16.34, thiab GB / T 12236.

Qhov no valve lub versatility spans huv kua (dej, ncu) mus aggressive media (corrosive acids, hydrocarbons), ua rau nws yog ib tug universal xaiv rau industrial kua.

Cov yam ntxwv tseem ceeb

Vertical Lift Check Valve muab kev ua haujlwm tsis sib xws los ntawm kev tsim kho tshiab:

Ceev ceev, Dej rauj-Resistant kaw

Short disc stroke enables instant sealing, minimizing siab surges uas puas pipelines thiab twj.

Zero-Leak Sealing

Hlau -rau-hlau los yog mos- zaum (Buna-N, FKM, PTFE) ua khub kom kaw nruj txawm tias muaj kua nplaum los yog corrosive media.

Low Maintenance Reliability

Tsuas yog ib feem ntawm qhov txav mus, lub valve yuav tsum tau saib xyuas tsawg kawg nkaus - tseem ceeb rau cov chaw taws teeb lossis nyuaj - mus rau - nkag mus rau kev teeb tsa.

Corrosion & Hnav Resistance

Fluorine-lined lub cev thiab cov rooj zaum tawv (stainless steel, carbide) tiv taus cov xov xwm hnyav hauv cov tshuaj lom neeg thiab thaj chaw sab nrauv.

Kev txhim kho yooj yim

Caij nplooj ntoos hlav- cov qauv thauj khoom hloov mus rau cov kav dej ntsug lossis kab rov tav, thaum flange / wafer sib txuas ua kom yooj yim rau kev sib koom ua ke.

Cov ntawv thov kev lag luam

Lub valve no daws cov teeb meem rov qab los ntawm cov haujlwm:

Roj & Gas / Petrochemicals

Tiv thaiv kev thim rov qab ntawm cov roj av, roj av, thiab cov kuab tshuaj nyob rau hauv refineries thiab offshore platforms.

Lub zog tiam

Ruaj ntseg chav thiab dej txias cov kab hauv thermal thiab nuclear nroj tsuag, kom ntseeg tau tias tsis muaj kev cuam tshuam kev tsim hluav taws xob.

Dej & Dej pov tseg

Khaws cov kev taw qhia ntws hauv cov tshuab faib khoom, tsis txhob muaj kev sib kis ntawm theem kev kho mob.

Tshuaj / Pharmaceutical

Fluorine- cov kab sib txawv ua rau cov kua qaub, alkalis, thiab cov kua dej tsis muaj menyuam, ua raws li cov qauv kev nyiam huv.

HVAC & Tsev Kev Pabcuam

Tswj dej txias / dej kub ntws, tiv thaiv kev tsis sib haum xeeb thiab lub zog pov tseg.

Marine & Shipbuilding

Withstands saltwater corrosion nyob rau hauv ballast thiab roj systems.

FAQ

Q1: Dab tsi yog Vertical Lift Check Valve txawv ntawm lub viav vias kos valve?

A: Tsis zoo li viav vias kos li qub (uas pivot ntawm pob khawm), ntsug nqa li qub siv lub piston-zoo li disc uas swb ntsug. Qhov kev tsim no muaj kev kaw nrawm dua, txo qis qis, thiab zoo dua rau cov kav me me - rau - nruab nrab txoj kab uas hla . Lub viav vias li qub ua tau zoo nyob rau hauv cov kab loj loj tab sis nws yooj yim rau dej rauj.

Q2: Nws puas tuaj yeem ntsia tau kab rov tav?

A: Yog lawm- caij nplooj ntoos hlav- cov qauv thauj khoom cia siab rau lub caij nplooj ntoos hlav quab yuam (hloov lub ntiajteb txawj nqus) kaw, ua kom muaj kab rov tav lossis ntsug. Tsis yog - caij nplooj ntoos hlav variants xav tau ntsug mounting siv disc hnyav rau sealing.

Q3: Cov xov xwm dab tsi yog nws tsis sib haum nrog?

A: Nws ua haujlwm nrog cov kua dej feem ntau (dej, ncu, roj, tshuaj) tab sis tsis pom zoo rau cov slurries heev, uas tuaj yeem hnav lub disc thiab lub rooj zaum. Rau xws li daim ntawv thov, qhia cov hardfaced Cheebtsam.

Q4: Kuv yuav xaiv qhov loj thiab qhov ntsuas siab li cas?

A: Ua kom lub valve loj rau koj txoj kab uas hla (NPS / DN) thiab xaiv qhov ntsuas siab tshaj koj lub cev qhov siab tshaj plaws kev khiav hauj lwm siab (piv txwv li, Chav Kawm 300 rau 232 psi systems). Nrog peb cov engineers rau kev cai tshaj tawm kev sib raug zoo (xws li, fluorine hauv ob sab phlu rau cov kua qaub).

Q5: Yuav tsum muaj kev saib xyuas dab tsi?

A: Tshawb xyuas lub rooj zaum thiab disc txhua xyoo rau hnav. Ntxuav lub tes tsho qhia kom paub meej tias kev txav mus los zoo. Hloov cov ntsaws ruaj ruaj txhua 2-3 xyoos hauv siab - daim ntawv thov mus ncig

Q6: Nws puas ua haujlwm nrog lub tshuab nqus tsev?

A: Yog lawm- caij nplooj ntoos hlav- cov qauv thauj khoom nrog qis qhib siab (1/2-2 psi) yog qhov zoo tagnrho rau cov kab nqus dej, tiv thaiv cov twj tso kua mis cavitation los ntawm kev tuav cov prime.
