1. Cov yam ntxwv tsis zoo
Unfused yog hais txog qhov tshwm sim uas cov hlau welded tsis yog tag nrho melted thiab sib txuas nrog lub hauv paus hlau los yog nruab nrab ntawm cov khaubncaws sab nraud povtseg ntawm cov hlau weld.
Tsis nkag mus yog hais txog qhov tshwm sim uas cov hauv paus hniav ntawm cov welded sib koom tsis tau nkag mus tag nrho.
Ob qho tib si uas tsis yog-fusion thiab tsis nkag mus yuav txo qhov kev sib tshuam ntawm qhov chaw ntawm qhov vuam, txo lub zog thiab nruj.
2. Ua rau
Qhov ua rau tsis muaj fusion: qhov vuam tam sim no me me dhau los yog qhov vuam ceev nrawm dhau, ua rau cov cua sov tsis txaus, thiab cov hlau hauv paus thiab cov hlau muab tub lim tsis tuaj yeem yaj tag nrho. Lub kaum sab xis me dhau lawm, qhov sib txawv yog nqaim dhau los yog lub ntsej muag blunt loj dhau, yog li cov arc tsis tuaj yeem nkag mus tob rau hauv lub hauv paus ntawm qhov zawj thaum vuam, ua rau lub hauv paus hlau thiab vuam hlau tsis fused. Muaj cov impurities xws li roj stain thiab xeb nyob rau saum npoo ntawm lub vuam, uas cuam tshuam rau melting thiab fusion ntawm cov hlau. Kev ua haujlwm tsis raug, xws li lub kaum sab xis electrode tsis raug, txoj kev thauj khoom tsis zoo, thiab lwm yam, ua rau lub arc deviate los ntawm ntug ntawm qhov zawj lossis ua tsis txaus npog qhov zawj.
Ua rau tsis muaj kev nkag mus: Zoo ib yam li qee qhov laj thawj rau kev tsis sib haum xeeb, xws li cov vuam tam sim no me me, vuam ceev heev, qhov zawj tsis tsim nyog, thiab lwm yam. Thaum vuam, qhov arc ntev dhau lawm, thiab cov cua sov arc dispersed, ua rau cov hlau tsis zoo melting. Kev sib dhos qhov sib txawv ntawm qhov vuam tsis sib xws, thiab nws yog ib qho yooj yim kom tsis muaj vuam nkag rau hauv ib feem nrog qhov sib txawv loj.
3. Kev ua haujlwm
Kev kho tsis raug: Rau qhov chaw uas tsis yog fused, lub log sib tsoo tuaj yeem siv los txhuam cov khoom tsis siv thiab rov ua dua. Thaum rov vuam, cov txheej txheem vuam yuav tsum tau hloov kho kom ntseeg tau tias muaj cov cua kub txaus los ua kom tag nrho cov hlau thiab cov hlau muab tub lim. Rau sab hauv uas tsis yog-fusion, nws yog ib qho tsim nyog yuav tsum tau siv cov kev ntsuas uas tsis yog kev puas tsuaj los txiav txim siab qhov chaw thiab qhov twg ntawm qhov tsis yog fusion, thiab tom qab ntawd siv cov pa roj carbon arc gouging lossis machining txoj kev los tshem tawm cov khoom tsis yog fusion, thiab tom qab ntawd ua haujlwm kho vuam. Thaum kho vuam, ua tib zoo saib xyuas qhov zawj, tswj lub vuam lub kaum sab xis thiab txoj hauv kev ntawm kev thauj cov bar.
Kev kho impervious: Yog hais tias qhov tob ntawm unwelded nkag mus rau qhov ntiav, qhov tsis muaj qhov nkag tuaj yeem raug tshem tawm los ntawm kev sib tsoo nrog lub log sib tsoo, thiab tom qab ntawd kho vuam. Rau qhov tob loj, feem ntau nws yog qhov yuav tsum tau siv cov pa roj carbon arc gouging lossis machining kom tshem tawm tag nrho cov seem ntawm cov vuam nkag mus txog thaum cov hlau zoo raug, thiab tom qab ntawd kho vuam. Thaum kho vuam, vuam tam sim no, qhov hluav taws xob thiab vuam ceev yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias cov hauv paus hniav tuaj yeem nkag mus tau tag nrho.
4. Kho cov khoom siv vuam
Feem ntau, cov khoom siv vuam uas zoo ib yam lossis zoo ib yam li cov khoom siv ntawm lub valve yuav tsum raug xaiv. Piv txwv li, rau cov pa roj carbon steel li qub, E4303 (J422) vuam rods tuaj yeem xaiv tau; Rau stainless hlau li qub, cov sib txuas stainless hlau vuam pas nrig tuaj yeem xaiv raws li cov ntaub ntawv tshwj xeeb, xws li A102 vuam pas nrig rau 304 stainless hlau.li qub, A022 vuam pas nrig rau 316L stainless hlauli qub, lwm.
Tianjin Tanggu Dej-Foob Valve Co., ltd mas tsimnpauj npaim valve, qhov rooj valve,Y- lim, ntsuas valve, check valve, thiab lwm yam.
