Nyob rau hauv lub Jinbin Rhiav, peb custom-madeiav valvesrau cov neeg muas zaub tab tom ua kom tiav. Cov neeg ua haujlwm tab tom ua qhov kawg ntawm lawv. Cov no yog kiv cuazoo li tus dig muag valvesnrog rau qhov loj ntawm DN1450, nruab nrog lub tshuab hluav taws xob. Lawv tau dhau los ua qhov kev sim siab nruj thiab qhib thiab kaw thiab tos kom tau ntim thiab xa tawm.

Loj-inch sector dig muag phaj valve nrog ib txoj kab uas hla ntawm DN1000 thiab saum toj no yog cov cuab yeej tseem ceeb tsim los ua kom tau raws li cov kev cai cais ntawm super-loj txoj kab uas hla pipeline systems.

Nyob rau hauv cov nqe lus ntawm qhov zoo, thawj tus yog nws zoo sealing kev ua tau zoo. Hom valve no feem ntau siv cov qauv kev sib khi dual ntawm "elastic foob + hlau tawv foob", uas tseem tuaj yeem ua tiav xoom xaim txawm tias nyob hauv qhov loj ntawm DN1000 thiab siab dua. Nws yog tshwj xeeb tshaj yog haum rau cov xwm txheej uas yuav tsum tau nruj sealing xws li cov pa roj thiab cov tshuaj lom neeg tawm, zam qhov teeb meem ntawm lub zog tsis sib xws ntawm lub sealing nto tshwm sim los ntawm loj diameters.

Thib ob, nws ua haujlwm tau zoo thiab yooj yim rau kev khiav lag luam. Lub kiv cua zoo li tus qauv yog compact dua li cov tsoos dig muag phaj, thiab nws qhov hnyav tsuas yog 60% ntawm lub rooj vag valve ntawm tib txoj kab uas hla. Nws tuaj yeem ua ke nrog cov khoom siv hluav taws xob thiab pneumatic tsav kom ua tiav cov chaw taws teeb qhib thiab kaw, daws qhov teeb meem ntawm kev siv zog ua haujlwm ntawm qhov loj-inch li qub. Lub sijhawm qhib thiab kaw ntawm ib lub valve feem ntau yog tswj tsis pub dhau 30 vib nas this, txhim kho kev ua haujlwm zoo.

Tsis tas li ntawd, nws muaj kev ruaj ntseg redundancy, nruab nrog mechanical locking pab kiag li lawm thiab txwv keyboards los tiv thaiv tsis ua hauj lwm. Lub qhov muag tsis pom lub cev yog ua los ntawm lub zog siab cam khwb cia hlau lossis welded steel daim hlau, uas tuaj yeem tiv taus siab (feem ntau txog 1.6MPa) thiab cuam tshuam, thiab tsim nyog rau kev ua haujlwm nyuaj. Tsis tas li ntawd, tus nqi kho mob tsawg. Lub sealing qhov chaw tuaj yeem disassembled thiab hloov nyias yam tsis tas yuav disassemble tag nrho cov kav dej. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau cov xwm txheej tsim khoom tas mus li hauv cov kav dej loj loj uas "kev kaw cia txhais tau tias poob".

Cov xwm txheej ntawm daim ntawv thov feem ntau yog tsom rau hauv cov cheeb tsam tseem ceeb uas yuav tsum muaj cov kab loj loj: Hauv kev tsim hluav taws xob hauv nroog, feem ntau yog siv rau hauv cov kav dej loj hauv nroog cov pa roj carbon monoxide nrog cov diameters xws li DN1200 mus rau DN2000, kom ua tiav kev nyab xeeb kev faib tawm thaum lub sij hawm tu kav dej thiab cov ceg txuas, kom tsis txhob muaj hluav taws xob loj. Nyob rau hauv atmospheric thiab nqus distillation units thiab catalytic cracking units ntawm petrochemical kev lag luam, lub ntsiab pipelines rau thauj cov roj crude thiab refined roj cov khoom uas muaj ib txoj kab uas hla ntawm tshaj DN1000 yuav tsum nquag hloov cov txheej txheem los yog cais cov khoom.

Lawv cov yam ntxwv qhib thiab kaw nrawm tuaj yeem txo cov sijhawm cuam tshuam ntau lawm. Nyob rau hauv cov ntub dej desulfurization / denitrification systems ntawm lub hwj chim kev lag luam, nws yog haum rau lub ntsiab flue gas pipelines nrog ib txoj kab uas hla ntawm DN1500 los yog ntau tshaj, thiab muaj peev xwm cais high-temperature flue gas (nrog rau kub tsis kam mus txog 300 ℃) thaum lub sij hawm kho reactor. Kev tshem tawm cov plua plav qhuav rau lub tshuab hluav taws xob tawg hauv kev lag luam metallurgical xav kom cov kav dej xa hluav taws xob nrog lub cheeb ntawm DN1200 thiab saum toj no yuav tiv taus kev yaig ntawm cov plua plav tawm. Nws cov hlau nyuaj sealing qauv tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev.

Raws li 20-xyoo-laus chaw tsim tshuaj paus ntawm metallurgical li qub (Electric Blind Valve), Jinbin Valves muab cov neeg siv khoom nrog cov kev tswj xyuas dej zoo thiab kev pabcuam ib leeg. Yog tias koj muaj lus nug ntsig txog, thov hu rau peb hauv qab no thiab koj yuav tau txais lus teb tsis pub dhau 24 teev!
