Kwiworkshop yeJinbin, ibhetshi yeiivalvu zebhola yentsimbi yekhabhoni eneflangedzipakishwa kwiibhokisi ukuze zithunyelwe.

Ziziphi izicelo ezikhethekileyo zentsimbi ye-carbon flangedivalve yebhola?

I. Iimeko ezingundoqo kuShishino lwePetrochemical

Njengeyona ndawo isetyenziswa kakhulu, ifanelekile kwiimeko zokusebenza ezifana nokucocwa kwe-oyile ekrwada kunye ne-chemical synthesis. Ngokomzekelo, kwimibhobho yokuthutha imveliso yeoli yobushushu obuphezulu bokucokisa kunye namashishini ekhemikhali, iimpawu zabo zokuvula kunye nokuvala ngokukhawuleza kunokuthintela ukugcinwa okuphakathi kunye ne-oxidation. Isakhiwo somlilo kunye ne-anti-static sihambelana nomgangatho we-API 607, ukuqinisekisa ukhuseleko lwemveliso.

Ii. Ukusetyenziswa kweeNkqubo zaMandla oMbane

Kumandla obushushu kunye neeprojekthi zokudibanisa, isetyenziselwa ukondla amanzi kwibhoyila kunye nemibhobho yokuhambisa umphunga. Ifanelekele umphunga woxinzelelo oluphezulu kunye neemeko zokusebenza ezinobushushu obuphezulu, ukuzinza koqhagamshelo lweflange kunokuxhathisa ukungcangcazela kombhobho, kwaye inkqubo yokubumba iyonke yomzimba wevalve inyusa amandla okuxhathisa ukuguqulwa koxinzelelo. Kwiinkqubo ezincedisayo zamandla enyukliya, ushishino lwevalvu yebhola eyenziwe ngentsimbi yekhabhoni yobushushu obuphantsi (LCB) inokuqhelaniswa neemeko zecryogenic ze -46 ℃, ibonelela ngolawulo oluthembekileyo lokuvalwa kwemibhobho yokupholisa amanzi.

Iii. Unxulumano olungundoqo kuShishino lweMetallurgical

Isetyenziselwa ukujikeleza kwamanzi okupholisa kunye nenkqubo yokuhambisa igesi yesithando somlilo kwi-smelting yensimbi. Xa evezwe kumajelo eendaba aqulathe uthuli kunye nezinto ezinokudlakaza kancinci, umzimba wevalve yentsimbi yekhabhoni udityaniswe neebhola eziqinileyo zentsimbi engatyiwayo ukumelana nokukhukuliseka kwamasuntswana kunye nokunxiba. Isakhiwo sokucoca isihlalo se-valve sinciphisa umngcipheko wokuvala. Kwimibhobho yonyango yegesi yokuguqula i-flue, iimpawu zayo ze-torque encinci yokusebenza kunye nokuvulwa ngokukhawuleza kunye nokuvalwa kunokusabela ngokukhawuleza ekutshintsheni koxinzelelo lwenkqubo kunye nokuqinisekisa ukusebenza kakuhle kokucocwa kwegesi ye-flue.

Iv. Iimeko zikaMasipala kunye nezoShishino Jikelele

Kwiiprojekthi zokubonelela ngamanzi asezidolophini kunye neeprojekthi zokucocwa kogutyulo, i-valve yebhola ye-Intshi ye-4 eyenziwe ngentsimbi etyhidiweyo kunye ne-carbon steel ifanelekile kumajelo angenakonakala afana namanzi ompompo kunye namanzi ajikelezayo. Banikezela ngokusebenza kweendleko ezibalaseleyo, kwaye uqhagamshelo lweflange luququzelela ukugcinwa nokuhlolwa kamva. Kwimibhobho ye-disinfection ye-steam ye-pharmaceutical and food industries, iivalve zebhola ze-carbon steel ezingenazo iziteshi zokuhamba zekona ezifileyo zikhethwa ukukhusela i-residu ephakathi kunye nokuhlangabezana neemfuno zococeko.

V. Isicelo kwiNdawo yoThutho kunye noSasazo lweGesi

Kwizikhululo zamasango asezidolophini kunye nemibhobho yerhasi yendalo enomgama omde, i-carbon steel flanged valve yebhola iye yaba sisixhobo esingundoqo sokunqunyulwa okuphakathi ngenxa yokutywinwa komlilo kunye noyilo oluchasene ne-static. Isakhiwo sebhola esisigxina sifanelekile kwimibhobho yobubanzi obukhulu ukusuka kwi-DN50 ukuya kwi-DN600. Iqinisekisa ukutywinwa okuzinzile phantsi koxinzelelo lwe-ultra-high umahluko kwaye inokudibaniswa kude nenkqubo ye-ESD ukufezekisa ukuvala ngokukhawuleza, iqinisekisa ukhuseleko lokuhanjiswa kwegesi.
