Tsis ntev los no, Jinbin valve tau ua tiav qhov kev tsim khoom ntawm 6 daim DN1600 riam rooj vag li qub thiab DN1600 npauj npaim buffer check li qub. Cov pawg ntawm cov li qub no yog txhua yam casting.

Hauv lub rooj cob qhia, cov neeg ua haujlwm, nrog kev koom tes ntawm cov khoom siv hoisting, tau ntim lub qhov rooj riam nrog lub cheeb ntawm 1.6m thiab lub npauj npaim buffer check valve nrog lub cheeb ntawm 1.6m feem rau hauv lub tsheb thauj khoom, thiab tom qab ntawd xa tawm mus rau Russia.

Cov khoom siv no tau txais kev tshuaj xyuas los ntawm lwm tus. Txhawm rau kom ntseeg tau tias cov khoom siv muaj kev nyab xeeb thiab kev ntseeg siab, ntxiv rau kev sim lub zog ntawm cov khoom siv ntawm qhov siab ntawm 1.25 ~ 1.5 npaug ntawm qhov siab nominal ua ntej tawm hauv Hoobkas, qhov zoo sab nraud thiab qhov zoo sab hauv ntawm cov khoom seem kuj tau raug tshuaj xyuas. Peb lub valve tau dhau qhov kev xeem casting, cov khoom siv, siab thiab lwm yam los ntawm lwm tus, thiab tau dhau qhov kev xeem zoo.

Cov kev xav tau ntawm cov neeg siv khoom yog qhov siab heev. Qhov chaw ntawm qhov casting yuav tsum du thiab meej, tshwj xeeb tshaj yog nrog cov qauv ntom, thiab yuav tsum tsis muaj qhov tsis zoo xws li qhov hws, qhov ntsws, qhov xoob, tawg thiab xuab zeb qhwv. Yuav kom ua tau raws li cov kev xav tau saum toj no, yuav tsum muaj ntau yam kev ntsuas thaum lub sijhawm casting, xws li xaiv cov ntaub ntawv molding uas tiv taus hluav taws siab thiab tswj cov dej noo ntawm cov xuab zeb molding. Thaum lub sijhawm molding, nws yuav tsum tau compacted ua txheej kom ntseeg tau tias cov xuab zeb pwm tawv, siv cov txheej txheem pouring thiab riser tsim nyog thiab tswj hwm qhov ceev thiab kub ntawm pouring. Txawm li cas los xij. Vim yog cov kev xav tau siab, cov txheej txheem casting ntawm lub valve nyuaj dua li cov castings ib txwm muaj. Yuav kom tau txais cov khoom zoo, cov castings sib xws xav tau kev kho cua sov kom tshem tawm kev ntxhov siab hauv cov txheej txheem casting. Tib lub sijhawm, X-ray, magnetic particle flaw detection, penetrant inspection thiab lwm yam kev kuaj pom siv.

Jinbin valve yog ib lub chaw tsim khoom siv valve uas koom nrog kev tshawb fawb thiab kev txhim kho, kev tsim khoom thiab kev muag khoom, kev sib koom ua ke ntawm kev tshawb fawb, kev lag luam thiab kev lag luam. Nws feem ntau tsim cov riam rooj vag valve, penstock rooj vag valve, slide gate valve, goggle valve thiab lwm yam khoom ntawm ntau yam kev qhia tshwj xeeb. Tau ntau xyoo, lub tuam txhab valve tau tsom mus rau kev tsim khoom siv valve thiab ua raws li kev tsim kho tshiab ywj pheej.
