Dab tsi yog ob qho kev sib txuas rau li qub? Cov qauv muaj pes tsawg leeg thiab lub hauv paus ntsiab lus ua haujlwm ntawm hluav taws xob kaw ntsaws valve Threaded kev twb kev txuas Qhov no yog ib qho yooj yim kev twb kev txuas txoj kev, feem ntau siv rau me me li qub. Muaj ob qhov xwm txheej: 1, kev sib khi ncaj qha: cov xov sab hauv thiab sab nraud ncaj qha ua lub luag haujlwm ntawm kev sib khi. Txhawm rau kom ntseeg tau tias qhov sib koom ua ke tsis xau, feem ntau nrog cov roj txhuas, linoleum thiab PTFE raw khoom ntim; Ptfe raw khoom siv, siv qhov chaw muaj koob muaj npe; Cov khoom no muaj kev tiv thaiv corrosion zoo, zoo sealing nyhuv, siv thiab cia sab Threaded kev twb kev txuas Qhov no yog ib tug yooj yim kev twb kev txuas txoj kev thiab feem ntau yog siv nrog me me li qub. Muaj ob qhov xwm txheej ntxiv: 1, kev sib khi ncaj qha: cov xov sab hauv thiab sab nraud ncaj qha ua lub luag haujlwm ntawm kev sib khi. Txhawm rau kom ntseeg tau tias qhov sib koom ua ke tsis xau, feem ntau nrog cov roj txhuas, linoleum thiab PTFE raw khoom ntim; Ptfe raw khoom siv, siv qhov chaw muaj koob muaj npe; Cov khoom no muaj kev tiv thaiv corrosion zoo, zoo sealing nyhuv, yooj yim rau siv thiab khaws cia, thiab thaum disassembled, nws yuav raug tshem tawm tag nrho, vim hais tias nws yog ib tug uas tsis yog-viscous zaj duab xis, zoo dua li cov roj txhuas thiab linoleum. 2. Indirect sealing: lub zog ntawm cov ntsia hlau nruj yog hloov mus rau lub tshuab ntxhua khaub ncaws ntawm ob lub dav hlau, kom lub tshuab ntxhua khaub ncaws ua lub luag haujlwm sealing. NYEEM NTXIV HAUV HAUS HAUJ LWM, DIRT, lossis lwm yam khoom siv sab nraud hauv kab tuaj yeem cuam tshuam qhov kev ua haujlwm ntawm lub valve thiab ua rau puas tsuaj rau lub valve tseem ceeb. Sab hauv ntawm cov yeeb nkab yuav tsum tau ntxuav kom huv si nrog cua lossis chav. Thaum TAPPING yeeb nkab, ntsuas qhov loj thiab qhov ntev ntawm cov yeeb nkab xov kom tsis txhob txhaws cov yeeb nkab nrog cov rooj zaum thiab discs. Ua tib zoo ntxuav xov xaus kom tsis txhob muaj teeb meem hlau lossis hlau tso nyiaj. Siv teflon daim kab xev los yog cov yeeb nkab adhesives kom muaj zog welds. Siv cov yeeb nkab nplaum tsuas yog me me ntawm cov yeeb nkab xov, tab sis tsis yog *** ntawm valve threads. Tsis txhob tso cai rau cov yeeb nkab nplaum kom ntws mus rau hauv lub cev kom tsis txhob muaj kev puas tsuaj rau DISC thiab lub rooj zaum. Ua ntej kev teeb tsa, txiav tawm qhov ntws los ntawm lub valve kom lub valve ua haujlwm zoo. Kaw valve kom tiav ua ntej kev teeb tsa. Muab cov ciaj ntswj rau ntawm lub taub hau hex ntsia liaj qhov rooj ze ntawm cov yeeb nkab kom tsis txhob muaj deformation. Tom qab txhim kho lub valve, txhawb nqa cov yeeb nkab: SAGGING yeeb nkab tuaj yeem deform lub valve thiab ua rau tsis ua hauj lwm. Flange kev twb kev txuas Qhov no yog feem ntau hom ntawm valve kev twb kev txuas. Raws li cov duab ntawm qhov sib koom ua ke, nws tuaj yeem muab faib ua cov hauv qab no: 1. Hom du: siv rau cov li qub uas tsis tshua muaj siab. Kev ua haujlwm yooj yim 2, concave thiab convex hom: kev ua haujlwm siab, tuaj yeem siv rau hauv lub tshuab ntxhua khaub ncaws nyuaj 3. Tenon thiab groove hom: gasket nrog cov yas deformation loj tuaj yeem siv rau hauv cov xov xwm corrosive, thiab cov nyhuv sealing zoo dua. 4, trapezoidal zawj: siv lub nplhaib hlau oval ua lub tshuab ntxhua khaub ncaws, siv rau kev ua haujlwm siab ≥64 kg / cm2 valve, lossis siab kub valve. 5, hom lens: lub tshuab ntxhua khaub ncaws yog lub lens zoo, ua los ntawm hlau. Rau siab siab li qub nrog kev ua haujlwm siab ≥100 kg / cm2, los yog kub li qub. 6, O nplhaib hom: Qhov no yog ib daim ntawv tshiab ntawm flange kev twb kev txuas, nws yog tsim nrog cov tsos ntawm tag nrho cov hom roj hmab O nplhaib, nws yog ntau txhim khu kev qha tshaj lub tiaj tus ntxhua khaub ncaws nyob rau hauv lub sealing nyhuv. Txhawm rau kom muaj kev sib txuas ntawm flange kom raug, ua raws li cov kauj ruam no. Ua ntej ua tib zoo ntxuav cov pob qij txha, tom qab ntawd xoob txuas ob lossis peb bolts rau hauv paus. Tom ntej no, ua tib zoo ntxig lub spacer rau hauv qhov sib koom ua ke. Cov ntsia liaj qhov rooj hauv qab yuav pab kom muab lub gasket thiab khaws cia rau hauv qhov chaw. Ntxig bolts yuav tsum tau hla-tightened es tsis yog WRAPAROUND, uas yuav pab kom tshem tawm cov concentration ntau dhau. Tom qab siv ib txwm siv rau lub sijhawm, xyuas kom tag nrho cov bolts tau nruj thiab rov nruj raws li qhov tsim nyog. Hluav taws xob kaw lub rooj vag valve yog tsim los ntawm lub ntsiab thiab pabcuam valve lub cev, valve phaj, expansion sib koom tes, ruaj lub tes tsho, electro-hydraulic laub pas nrig clamping mechanism, taug kev hluav taws xob installation, limiter, sab laug thiab txoj cai valve lub cev thiab lwm yam khoom. Valve kaw: electro-hydraulic laub pas nrig tsav caij nplooj ntoos hlav clamping mechanism, lub valve phaj tawm, nyob rau hauv qhov chaw, taug kev hluav taws xob pib, tsav lub valve phaj taug kev los ntawm qhib rau kaw, nyob rau hauv qhov chaw, electro-hydraulic laub pas nrig rov qab motion, caij nplooj ntoos hlav clamping mechanism txiav. clamped nyob rau hauv qhov chaw, qhov kawg ntawm valve kaw. Qhib valve yog vice versa. Cov qauv muaj pes tsawg leeg thiab kev ua haujlwm ntawm lub tshuab hluav taws xob kaw lub valve Hluav taws xob kaw ntsaws valve yog tsim los ntawm lub ntsiab thiab pabcuam valve lub cev, valve phaj, expansion sib koom tes, lub tes tsho ruaj khov, electro-hydraulic laub pas nrig clamping mechanism, taug kev hluav taws xob installation, limiter, sab laug thiab sab xis valve lub cev thiab lwm yam khoom. Valve kaw: electro-hydraulic laub pas nrig tsav caij nplooj ntoos hlav clamping mechanism, lub valve phaj tawm, nyob rau hauv qhov chaw, taug kev hluav taws xob pib, tsav lub valve phaj taug kev los ntawm qhib rau kaw, nyob rau hauv qhov chaw, electro-hydraulic laub pas nrig rov qab motion, caij nplooj ntoos hlav clamping mechanism txiav. clamped nyob rau hauv qhov chaw, qhov kawg ntawm valve kaw. Qhib valve yog vice versa. Qhib GATE VALVE, POOB GATE VALVE yog qhov tsim nyog rau METALLURGY, CHEMICAL INDUSTRY, MUNICIPAL GAS pipeline, nyob rau hauv kab nrog GB6222-86 "Industrial ENTERPRISE GAS SAFETY REGULATIONS". Thaum lub tshuab hluav taws xob kaw lub valve yog nyob rau hauv lub xeev kaw, txiav tawm tag nrho cov nruab nrab hauv lub raj xa dej, kom ua tiav xoom xaim sealing, cov khoom siv hluav taws xob kaw lub valve tuaj yeem nyob rau ntawm qhov chaw, chaw taws teeb ua haujlwm, yog cov roj zoo tagnrho thiab muaj kev phom sij, tshuaj lom. gas pipe network kev nyab xeeb muab faib khoom. Schematic kev tsim kho ntawm hluav taws xob kaw lub qhov rooj valve Lub ntsiab kev ua tau zoo rau hluav taws xob kaw qhov rooj valve: Nominal txoj kab uas hla (mm): DN800-3600 Nominal siab (MPa): 0.05, 0.1, 0.25 Qhov ntsuas kub (℃): ≤260 Siv nruab nrab: roj thiab lwm yam Cov tshuaj lom neeg, tsim kev puas tsuaj, cov roj hluav taws xob txuas txuas tus qauv: raws li GB9115-2000 Hluav taws xob kaw lub rooj vag valve qauv nta: lub plugboard valve yog tsim los ntawm lub cev pem hauv ntej, lub cev rov qab, lub phaj valve, lub cev telescopic, sab laug thiab sab xis sealing lub thawv, ib lub phaj los ntawm lub phaj thiab lub qhov muag tsis pom kev, lub tshuab hloov pauv, thiab cov cuab yeej loosening clamping. Lub loosening clamping ntaus ntawv ntawm metallurgical valve yog tsav los ntawm cov khoom siv hluav taws xob. Lub sprocket, saw thiab ntsia hlau txiv ntoo khub txuas nrog, thiab kev nthuav dav ntawm lub hauv siab yog tsav kom paub qhov clamping lossis loosening ntawm lub valve lub cev foob lub rooj. Lub valve txais SPROCket hom multi-point clamping mechanism, lub nplhaib sealing yog ob sab foob, ntsia rau ntawm lub phaj valve, lub sealing yog txhim khu kev qha thiab yooj yim los hloov. Sab saum toj qhia rail ntawm valve phaj yog nruab nrog longitudinal thiab transverse txav mechanism, thiab sab yog nruab nrog lub caij nplooj ntoos hlav mechanism thiab txwv log. Thaum lub clamping mechanism raug tso tawm kom tso lub valve phaj, lub caij nplooj ntoos hlav mechanism nqa lub valve phaj mus rau lub log txwv.
