Ntau thiab ntau lub teb chaws Suav tau xa tawm mus rau ntau lub teb chaws thoob ntiaj teb, thiab tom qab ntawd ntau tus neeg siv khoom txawv teb chaws tsis nkag siab txog qhov tseem ceeb ntawm Tuam Tshoj tus lej valve, hnub no peb yuav coj koj mus rau kev nkag siab tshwj xeeb, vam tias yuav pab tau peb cov neeg siv khoom.
Hauv Suav teb, cov hom valve thiab cov ntaub ntawv muaj ntau thiab ntau dua, kev npaj cov qauv valve kuj nyuaj dua; cov qauv valve feem ntau yuav tsum qhia txog hom valve, hom tsav, daim ntawv txuas, cov yam ntxwv ntawm cov qauv, lub siab nominal, cov ntaub ntawv nto sealing, cov ntaub ntawv lub cev valve thiab lwm yam. Cov qauv valve standardization ntawm kev tsim valve, kev xaiv, kev faib tawm, muab ib txoj hauv kev yooj yim rau cov neeg siv saib lub npe phaj yuav paub cov qauv ntawm ib hom valve, cov ntaub ntawv thiab cov yam ntxwv.
Tam sim no cia peb ua piv txwv:

Lub luag haujlwm ntawm kev txheeb xyuas lub valve
Kev txheeb xyuas lub valve hauv qhov tsis muaj cov duab kos valve, poob lub npe thiab cov khoom valve tsis tiav, kev siv lub valve kom raug, vuam cov khoom valve, kho thiab hloov cov khoom valve yog qhov tseem ceeb. Tam sim no lub valve cim, cov khoom siv txheeb xyuas thiab kev txheeb xyuas lub valve tau piav qhia hauv qab no:
Kev siv "kev paub txog lub valve" kev paub uas tau kawm, raws li daim ntawv lo thiab lub logo ntawm lub valve thiab lub valve ntawm xim pleev xim. Koj tuaj yeem txheeb xyuas pawg ntawm lub valve ncaj qha, cov qauv, cov khoom siv, txoj kab uas hla nominal, lub siab nominal (lossis lub siab ua haujlwm), cov khoom siv hloov pauv tau, qhov kub thiab kev kaw.
1.Lub npe phaj yog tsau rau ntawm lub cev valve lossis lub log tes. Cov ntaub ntawv ntawm lub npe phaj tiav dua thiab qhia txog cov yam ntxwv tseem ceeb ntawm lub valve. Raws li tus neeg tsim khoom ntawm lub npe phaj, rau tus neeg tsim khoom rau cov duab kos thiab cov ntaub ntawv ntawm lub valve hnav; raws li hnub tim ntawm lub Hoobkas siv rau kev kho; raws li lub npe phaj muab cov xwm txheej ntawm kev siv, los txiav txim siab qhov hloov pauv ntawm cov gaskets, cov ntaub ntawv phaj valve thiab cov duab nrog rau txiav txim siab qhov hloov pauv ntawm lwm qhov valve ntawm cov khoom.
2.Kev cim yog siv casting, lettering thiab lwm txoj hauv kev hauv lub cev valve cim lub valve nominal siab, ua haujlwm siab, nominal caliber thiab nruab nrab ntws kev taw qhia.
3.Lub valve muaj ib hom cim qhia qhib-kaw, nws tau qhib qhov ntsuas ntsuas lossis qhia qhov qhib thiab kaw ntawm tus xub. Throttle valves, cov qhov rooj vag tsaus nti tau sau nrog cov lus qhia hloov pauv ntawm qhov kawg ntawm lub log tes tau sau nrog tus xub taw rau qhov qhib-kaw.
