Needle Valve yog dab tsi
Koob li qub, qee zaum hu ua plunger li qub, yog tswj cov li qub thiab pab cov kws ua haujlwm kom tswj tau zoo thiab tswj cov dej ntws thiab siab. Lub precision yog ua tiav los ntawm qhov zoo txav ntawm lub ncej, uas ua rau lub gearbox txav lub piston raj nyob rau hauv zawv zawg zog ntawm qhib los yog kaw txoj hauj lwm, nyob ntawm seb qhov yuav tsum tau los ntawm cov kev tswj system.
Cov txiaj ntsig ntawm koob Valve
Yooj yim
Qhov yooj yim tshaj plaws ntawm li qub tsuas muaj ob txoj kev xaiv. Los yog qhov ntws qhib, lossis kaw. Koob li qub yog txawv kiag li nyob rau hauv no hais txog, raws li lawv tso cai rau koj xaiv ib tug tag nrho ntau yam ntawm midway xaiv. Koj tuaj yeem teeb tsa qhov ntws kom nws qis heev, tab sis tseem txav mus, lossis yuav luag ntawm qhov siab tshaj plaws, tab sis tsis heev. Qhov no tso cai rau huab adaptability. Txawm li cas los xij koj ntsib, koj yuav muaj peev xwm kho lub valve kom tau raws li nws.
Precision
Nrog rau rab koob valve, precision yeej ib txwm yuav yog tus naj npawb ib saib. Qhov no yog lub ntsiab lus tseem ceeb uas feem ntau ua rau tib neeg xaiv lub valve no dua lwm qhov. Vim tias rab koob tuaj yeem hloov mus rau cov qib me me, cov neeg siv tuaj yeem tswj cov dej ntws hauv qhov ntsuas qhov tseeb. Qhov no ua rau lub koob valve yog qhov kev xaiv zoo tshaj plaws rau qhov chaw uas muaj pes tsawg tus lej thiab kev ntsuas tseem ceeb.
Ua kom muaj zog ntxiv
Vim tias cov dej ntws tuaj yeem tswj tau qhov tseeb, cov neeg siv tuaj yeem ua tiav qib tsis tau pom dua ntawm kev ua haujlwm. Tsis txhob tso dej ntau dua li qhov tsim nyog thiab nkim roj lossis roj, cov neeg siv tuaj yeem siv tsuas yog qhov xav tau, txuag nyiaj thiab lub zog tib lub sijhawm.
Cov qib kev nyab xeeb siab
Raws li ib tug natural side-effect ntawm lub precision thiab adaptability ntawm cov li qub, cov no yog ib co ntawm cov zoo li qub nyob rau hauv lub lag luam niaj hnub no. Tsis muaj dab tsi ntws los ntawm qhov tshwj tsis yog nws txhais tau tias, txhais tau tias tsis tshua muaj feem cuam tshuam, tawg, lossis puas tsuaj uas tuaj yeem ua rau muaj xwm txheej txaus ntshai.

Hom koob Valve
Threaded koob valve (manually ua)
Feem ntau thiab ib txwm siv hom koob valve. Nws nta ib tug kov txuas nrog lub qia (plunger) nrog ib tug tapered kawg. Thaum tus kov yog tig, lub plunger txav vertically los ntawm cov threaded feem, kho qhov txaus los ntawm kev txav lub tapered kawg ze rau los yog deb ntawm lub rooj zaum valve. Lub threaded koob valve tso cai rau kev ceev ceev tswj ntawm tus nqi ntws.
Motorized koob valve
Automated koob li qub tuaj yeem ua haujlwm hydraulically, hluav taws xob, lossis pneumatically. Lawv muab qhov zoo ntawm cov chaw taws teeb ua haujlwm thiab automation. Qhov kev xaiv ntawm txoj kev actuation nyob ntawm daim ntawv thov qhov yuav tsum tau thiab muaj peev xwm. Kub thiab ntws sensors feem ntau yog siv los tswj cov actuators ntawm automated koob li qub.
Ncaj koob valve thiab lub kaum ntse ntse valve
Cov ntsiab lus no hais txog kev taw qhia ntawm inlet thiab qhov hluav taws xob ports txheeb ze rau ib leeg. Ib rab koob ncaj valve muaj qhov nkag thiab qhov hluav taws xob cov chaw nres nkoj ua raws li txoj kab ncaj nraim (180 degree los ntawm ib leeg), ua rau muaj kev ncaj ncees. Lub kaum ntse ntse valve muaj qhov nkag thiab qhov hluav taws xob ntawm lub kaum sab xis 90 degree. Lub koob ncaj nraim valve muaj txoj hauv kev tortuous ntws nrog lub siab poob siab dua, ua rau nws muaj kev cuam tshuam ntau dua rau cavitation thiab flashing, thaum lub kaum ntse ntse valve txo qhov kev poob siab thiab zoo dua rau qee yam kev siv.
Multiport koob valve
Multiport koob li qub muaj xws li tus qauv inlet chaw nres nkoj thiab ntau qhov chaw nres nkoj. Cov li qub no feem ntau yog siv rau cov cuab yeej nyeem ntawv siab thiab cov cuab yeej, txo cov naj npawb ntawm cov ntsiab lus hauv cov kav dej thiab txo qhov kev pheej hmoo ntawm kev xau lossis tsis ua haujlwm ntawm cov ntsiab lus txuas.
Dab tsi yog cov teeb meem tshwm sim nrog cov khoom ntawm koob Valve?
Cov kua dej tawm
Ib rab koob phiaj yuav tsum muab lub foob kaw ntov hauv qhov chaw kaw tag rau kev tiv thaiv ib qho kua dej xau. Thaum cov foob no raug cuam tshuam, cov kua dej tuaj yeem tshwm sim, ua rau muaj teeb meem kev nyab xeeb thiab kev ua haujlwm zoo. Yog vim li cas cov kua dej tawm hauv qhov chaw kaw tag nrho yog feem ntau hnav thiab tsim kua muag ntawm lub ntsaws los ntawm qhov system cov xov xwm. Txhawm rau daws qhov teeb meem no, nws raug nquahu kom hloov, ntawm qhov tsawg kawg nkaus, lub qia ntawm rab koob valve. Yog tias qhov teeb meem tshwm sim, qhov kev daws teeb meem zoo dua tuaj yeem hloov pauv tag nrho lub koob valve kom ntseeg tau tias muaj kev ruaj ntseg thiab kaw ntom ntom hauv qhov chaw kaw tag nrho.
Khoom particle buildup
Thaum lub koob valve tau daig rau hauv txoj haujlwm qhib, nws tuaj yeem ua rau cov kua dej tsis txaus thiab tsis muaj kev tswj xyuas kev ua haujlwm. Lub valve ua daig qhib feem ntau yog vim muaj cov khoom sib txuas ntawm cov khoom hauv lub valve. Yuav kom daws tau qhov teeb meem no, lub valve yuav tsum tau disassembled, thiab txhua yam khoom uas ua rau muaj kev cuam tshuam yuav tsum tau ua tib zoo tshem tawm kom lub valve rov ua haujlwm zoo.
Dab tsi yog Daim Ntawv Thov ntawm Needle Valves?
Ikev ntsuas
Koob li qub feem ntau yog siv rau hauv kev ntsuas thiab kev tswj xyuas kom meej tswj cov kua dej ntws tawm, ua rau lawv zoo tagnrho rau kev tiv thaiv cov twj paj nruag zoo nkauj los ntawm kev kub siab.
Flow tswj
Lawv ua tau zoo nyob rau hauv cov ntawv thov uas yuav tsum tau hloov kho qhov tseeb thiab kev tswj xyuas cov nqi qis.
On/off thiab throttle functions
Koob li qub tuaj yeem ua haujlwm raws li ob qho tib si rau / tawm thiab lub qhov valve, muab ntau yam hauv kev tswj ntau cov kua dej.
Tswj kua
Lawv tau ua haujlwm nyob rau hauv ntau qhov kev lag luam los tswj cov dej ntws ntawm cov pa, cua, roj, roj, dej, thiab cov kua dej zoo sib xws, ua rau lawv muaj txiaj ntsig zoo hauv ntau lub tshuab thiab cov txheej txheem.
Needle Valve ua haujlwm li cas
Muab cais nyob ib leeg
Kev rho tawm (shut-off) Valve uas Screw actuation tso cai rau lub valve qhib maj mam thiab cov xov qia yuav tsum tau peb lossis plaub zaug ntawm tus kov kom qhib thiab kaw lub valve. Rau qhov tshwj xeeb siab siab dav dav saum toj no 10.000 Psig (690 bar) nrog rau kev hloov tshwj xeeb ntawm rab koob li qub tau tsim. Txawm hais tias zoo ib yam li lwm cov koob li qub rau hom li qub no muaj cov qauv tsim tshwj xeeb nrog cov ntaub ntawv tshwj xeeb uas tau xaiv rau kev ua haujlwm siab.
Kev cai
Regulating thiab metering li qub muaj nuj nqi los tsim kho tus nqi ntws. Lawv ib txwm muaj qhov ntev zoo tapered qia taub thiab ib qho zoo pitch qia xov kom qhib nyob rau hauv tsib mus rau kaum lem.
Koob Valve Xaiv Cov Cai
Siab
Lub siab ua hauj lwm yog ib qho tseem ceeb hauv kev xaiv txoj cai koob valve. Cov muaj zog tuaj yeem tswj tau qhov siab txog li 4000-5000 psi (275-413 bar) ntawm 100 degree F (38 degree ). Thaum tseem xav tau siab dua, cov kev ua haujlwm siab muaj peev xwm ua tau txog li 10000 psi (689 bar) siab ntawm 100 degree F (38 degree).
Loj
Koob li qub muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab xaus kev sib txuas. Txiv neej / poj niam sib txuas nrog nti / metric threads tuaj yeem siv. Qhov feem ntau muaj li qub muaj qhov loj ntawm 2 mus rau 12 hli lossis 1/8 "rau 2". Kev siv qhov loj ntawm lub valve ua kom muaj txiaj ntsig zoo thiab kev ua haujlwm ntawm lub cev nrog tsawg dua kev hnav thiab to.
Kub
Koob li qub tuaj yeem ua haujlwm ntawm qhov kub thiab txias. Rau qhov kub thiab txias qhov ntim / sealing siv yog qhov tshwj xeeb. Ob lub hnab ntim khoom siv feem ntau yog PTFE (Teflon) rau qhov kub thiab txias ntawm -65 degree F txog 450 degree F ({2}} degree C txog 232 degree) thiab PEEK (Polyether Ether Ketone) rau qhov kub thiab txias. mus txog 600 degree F (315 degree).
Khoom siv
Ib tug xov tooj ntawm cov ntaub ntawv sib txawv yog siv nyob rau hauv lub valve kev tsim kho. Cov khoom siv feem ntau muaj xws li tooj dag, 304 lossis 316 stainless hlau, carbon steel thiab Alloy 400 (Nickel raws alloy). Stainless hlau yog dav siv rau nws cov corrosion kuj, tshuaj stability thiab kub tsis kam. Cov tooj dag yog siv rau hauv cov tshuab hydraulic, kev siv kub thiab kev siv roj. Alloy 400 yog siv rau nws lub zog siab, corrosion kuj thiab siv feem ntau hauv marine thiab tshuaj ua daim ntaub ntawv.

Periodic Inspection Koob Valve
Kev tawg
Kev tawg tuaj yeem tshwm sim yog tias dej khov hauv lub valve. Cov kab nrib pleb me me ntawm cov chaw nres nkoj yuav raug soldered; Txawm li cas los xij, cov kab nrib pleb ntawm lub cev valve yuav ua rau cov khoom hauv lub valve puas.
Kos
Cov khawb hauv txheej tuaj yeem ua rau corrosion. Rov kho lub valve kom sai li sai tau.
Discoloration
Discoloration yuav qhia tau tias lub valve kub dhau thiab cov khoom sab hauv puas.
Deformation
Deformation ntawm lub cev valve yuav tsum tau hloov lub koob valve.
