Cov lus piav qhia luv luv ntawm kev ua tau zoo ntawm ntau qhov tig valve hluav taws xob ntaus ntawv (Hom Z)

Cov lus piav qhia luv luv ntawm kev ua tau zoo ntawm cov khoom siv hluav taws xob ntau tig (Hom Z) Ib qho cuab yeej siv rau kev tswj qhov ntws, siab, thiab kev taw qhia ntawm cov kua dej (kua, roj, roj-kua, lossis cov khoom sib xyaw ua kua). Lub npe hu ua "valve. Feem ntau muaj lub cev valve, lub hau npog, lub rooj zaum, qhib thiab kaw qhov chaw, tsav tsheb mechanism, ntsaws ruaj ruaj thiab fasteners. , viav vias lossis tig los hloov qhov loj ntawm qhov ntws channel kom ua tiav *** yog siv hauv kev lag luam thiab kev ua liaj ua teb thiab cov khoom siv niaj hnub siv hauv Suav teb Ua ntej xyoo 2000 BC, xyoob kav thiab ntoo ntsaws li qub tau siv hauv cov kav dej. Nyob rau hauv Suav teb Tom qab, cov dej li qub tau siv rau hauv cov kav dej, cov phaj kos valve tau siv rau hauv cov tshuab nqus tsev, thiab cov kav dej xyoob thiab cov phaj kos valve tau siv rau hauv cov dej ntsev kom tshem cov dej ntsev nrog kev tsim cov tshuab smelting thiab hydraulic machinery. Cov tooj liab thiab cov hlau lead ntsaws li qub tau tshwm sim hauv Tebchaws Europe hauv xyoo 1681, lub pas nrig rauj kev nyab xeeb tau tshwm sim hauv xyoo 1769. Tom qab ntawd tuaj lub swb valve nyob ib ncig ntawm 1840, muaj lub ntiaj teb li qub nrog threaded qia thiab lub rooj vag valve nrog trapezoidal threaded qia. Tom qab ntawd, vim yog kev tsim hluav taws xob, roj av, tshuaj lom neeg kev lag luam thiab kev lag luam shipbuilding, daim ntawv thov ntawm ntau yam ntaub ntawv tshiab, txhua yam li qub tau yug los thiab tsim sai heev, valve manufacturing tau maj mam dhau los ua ib feem tseem ceeb ntawm kev lag luam machinery. Valves muaj dav. Raws li kev siv, nws tuaj yeem muab faib ua: ① thaiv valve. Siv los txiav tawm lossis muab tso rau hauv nruab nrab ntws, suav nrog lub rooj vag valve, lub ntiaj teb valve, diaphragm valve, ntsaws valve, pob valve, npauj npaim valve, thiab lwm yam. ② Tswj valve. Rau kev tswj cov dej ntws thiab lub siab ntawm cov kua dej, cov li qub ua nyob rau hauv Suav teb suav nrog kev tswj cov li qub, lub kaw lus valve, lub siab txo li qub thiab lwm yam. ③ Kuaj valve. Siv los txwv cov kua dej ntws rov qab. (4) lub valve. Siv rau kev xa tawm, sib cais thiab sib tov cov kua dej, suav nrog cov swb li qub, ntau txoj kev li qub, ntxiab, thiab lwm yam. ⑤ Kev nyab xeeb valve. Siv rau kev tiv thaiv kev ruaj ntseg overpressure, tiv thaiv boiler, siab hlab ntsha los yog cov kav dej puas, thiab lwm yam. Tsis tas li ntawd, raws li kev ua haujlwm siab tuaj yeem muab faib ua lub tshuab nqus tsev valve, tsis tshua muaj siab valve, nruab nrab siab valve, siab siab valve, ultra siab siab valve; Raws li kev ua haujlwm kub tuaj yeem muab faib ua qhov kub thiab txias, nruab nrab kub valve, qhov kub thiab txias valve, tsis tshua muaj kub valve; Raws li kev tsav tsheb, nws tuaj yeem muab faib ua phau ntawv valve, hluav taws xob valve, pneumatic valve, hydraulic valve, thiab lwm yam. Raws li cov yam ntxwv ntawm lub tuam tsev siv, nws tuaj yeem muab faib ua Marine valve, dej cua sov valve, fais fab chaw nres tsheb valve thiab lwm yam. Cov yam ntxwv tseem ceeb ntawm lub valve yog ua haujlwm siab, ua haujlwm kub thiab caliber. Ntau yam li qub ntawm cov kav dej, feem ntau siv nominal siab pN (siab tshaj plaws ua haujlwm siab tso cai rau dais hauv qab qhov ntsuas kub) thiab nominal txoj kab uas hla DN (nominal txoj kab uas hla ntawm lub cev lub cev thiab cov yeeb nkab txuas kawg) raws li qhov tseem ceeb tsis. Lub valve feem ntau yog kaw, lub zog, kev tswj hwm, kev ncig, qhib thiab kaw kev ua haujlwm, ntawm cov thawj ob yog qhov tseem ceeb tshaj plaws kev ua tau zoo ntawm tag nrho cov li qub. Txhawm rau kom muaj kev sib khi thiab lub zog ntawm lub valve, ntxiv rau cov qauv tsim nyog yuav tsum ua raws li cov qauv tsim nyog, ua kom cov txheej txheem zoo, tab sis kuj yuav tsum xaiv cov ntaub ntawv raug. Cov lus piav qhia ntawm kev ua tau zoo ntawm ntau qhov tig valve hluav taws xob ntaus ntawv (hom Z) Multi-tig valve hluav taws xob ntaus ntawv muaj kev ua haujlwm tag nrho, txhim khu kev qha kev ua haujlwm, kev tswj hwm qib siab, me me, lub teeb yuag, yooj yim siv thiab tu, thiab lwm yam *** yog siv. nyob rau hauv hluav taws xob fais fab, metallurgy, roj av, tshuaj lom neeg kev lag luam, ntawv ua, dej phwj kho mob thiab lwm yam departments. Multi-tig valve hluav taws xob ntaus ntawv, hu ua Z-hom. Nws yog qhov tsim nyog rau cov khoom siv hluav taws xob ntau tig nrog cov lus tsa suab ncaj, hu ua hom Z. Haum rau cov lus tsa suab ncaj nraim, xws li lub rooj vag valve, lub ntiaj teb valve, diaphragm valve, lub qhov rooj dej, thiab lwm yam. Siv rau valve qhib, kaw lossis hloov kho, yog lub valve kom ua tiav cov chaw taws teeb tswj, kev tswj hwm hauv nruab nrab thiab tsis siv neeg tswj kev tsav tsheb tseem ceeb. Multi-tig hluav taws xob ntaus ntawv, tsav ntaus ntawv, hluav taws xob lub taub hau, valve hluav taws xob installation qauv Multi-rotary valve hluav taws xob ntaus ntawv ua haujlwm ib puag ncig: 3.2.1 Ambient kub: -20 + 60 ℃ (tshwj xeeb txiav txim -60 + 80 ℃) 3.2.2 txheeb ze kub : 90% (ntawm 25 ℃) 3.2.3 Hom dav dav thiab sab nraum zoov yog siv rau hauv qhov chaw uas tsis muaj hluav taws xob / tawg thiab corrosive media; Cov khoom pov thawj tawg yog D ⅰ thiab D ⅱ BT4, D ⅰ yog qhov tsim nyog rau kev ua haujlwm tsis yog mining ntsej muag ntawm cov thee mine; D ⅱ BT4 siv nyob rau hauv factories, haum rau ib puag ncig ntawm ⅱ A, ⅱ B T1-T4 pawg ntawm kev sib deev roj sib tov. (Saib GB3836.1 kom paub meej) 3.2.4 Kev tiv thaiv qib: IP55 rau sab nraum zoov thiab tawg-pov thawj hom (IP67 tuaj yeem hloov kho). 3.3.5 Lub sijhawm ua haujlwm: 10 feeb (30 feeb tuaj yeem hloov kho). Multi-tig valve hluav taws xob ntaus ntawv (Hom Z) tsav ntaus ntawv, hluav taws xob lub taub hau, valve hluav taws xob ntaus ntawv, valve actuator, valve tsav, valve hluav taws xob actuator kev ua tau zoo Raws li kev siv ib puag ncig: Z yog hom hom; ZW yog hom sab nraum zoov; ZB yog flameproof; ZZ yog ib hom; ZT yog hom kev tswj hwm. Raws li qhov tso zis quab yuam: torque hom thiab thrust hom. Kev ua tau zoo ntawm cov khoom ua raws li JB / T8528-1997 "General hom valve hluav taws xob cov cuab yeej kev cai". Kev ua tau zoo ntawm cov khoom pov thawj tawg ua tau raws li cov kev cai ntawm GB3836.1-83 "Cov kev cai dav dav rau cov khoom siv hluav taws xob tawg rau ib puag ncig kev sib deev", GB3836.2-83 "Cov khoom tawg-pov thawj rau kev sib deev Ib puag ncig flameproof Hluav taws xob cov khoom siv D" thiab JB/T8529-1997 "Tsev kawm ntawv tej yam kev mob rau flameproof valve hluav taws xob ntaus ntawv".
