Kwiworkshop yeJinbin, ezintathu zenziwe ngokwesikoiivalvu zegogglekuba abathengi sele beza kugqitywa. Abasebenzi baqhuba inkqubo yokugqibela kubo. Aba ngabalandeliivalve eyimfama eyimfamaskunye nobukhulu be-DN1450, exhotyiswe ngesixhobo sombane. Baye bafumana uvavanyo olunzima loxinzelelo kunye novavanyo lokuvula kunye nokuvala kwaye balindele ukupakishwa kunye nokuthunyelwa.

Ivalve yepleyiti engaboniyo yecandelo elikhulu enobubanzi obuyi-DN1000 nangaphezulu zixhobo ezingundoqo eziyilelwe ukuhlangabezana neemfuno zokwahlulwa kweenkqubo zemibhobho yodayamitha emikhulu kakhulu.

Ngokumalunga neenzuzo, eyokuqala kukusebenza kwayo okubalaseleyo kokutywinwa. Olu hlobo lwevalve luthatha ulwakhiwo lokutywina kabini lwe "elastic seal + metal hard seal", olusenokufumana ukuvuza kwe-zero nangaphantsi kweedamitha ezinkulu ze-DN1000 nangaphezulu. Ifaneleke ngokukodwa kwiimeko ezineemfuno zokutywinwa ezingqongqo ezifana negesi kunye neendaba ezinobuthi, ukuphepha ingxaki yamandla angalinganiyo kwindawo yokutywina ebangelwa yi-diameters enkulu.

Okwesibini, iyasebenza kakhulu kwaye ikulungele ukusebenza. Ulwakhiwo olumise okwefeni ludityaniswe ngakumbi kunepleyiti eyimfama yemveli, kwaye ubunzima baso bungama-60% kuphela alo lwevalve yesango yobubanzi obufanayo. Inokudityaniswa kunye nezixhobo zombane kunye ne-pneumatic drive ukufikelela ekuvuleni nasekuvaleni kude, ukusombulula ingxaki yokusebenza kwencwadi enzima yeevalvu ezinobubanzi obukhulu. Ixesha lokuvula kunye nokuvala i-valve enye ngokuqhelekileyo ilawulwa ngaphakathi kwemizuzwana ye-30, iphucula kakhulu ukusebenza kakuhle.

Ngaphaya koko, ine-redundancy yokhuseleko eyomeleleyo, ixhotyiswe ngezixhobo zokutshixa ngoomatshini kunye nokutshintsha komda ukuthintela ukungahambi kakuhle. Umzimba we-valve oyimfama wenziwe ngentsimbi ephezulu okanye i-welded steel plates, enokumelana noxinzelelo oluphezulu (ngokuqhelekileyo ukuya kwi-1.6MPa) kunye nefuthe, kwaye ifanelekile kwiimeko zokusebenza ezinzima. Ukongeza, iindleko zokulondoloza ziphantsi. Amacandelo okutywinwa anokuchithwa kwaye atshintshwe ngokwahlukileyo ngaphandle kwesidingo sokuqhawula yonke imibhobho. Ilungele ngokukodwa iimeko zokuvelisa eziqhubekayo kwiinkqubo zemibhobho yobubanzi obukhulu apho "ukuvalwa kuthetha ukulahlekelwa".

Iimeko zesicelo zigxininiswe kakhulu kwiindawo eziphambili ezifuna izahlulo ezinobubanzi obukhulu: Kubunjineli begesi kamasipala, isoloko isetyenziswa kwimibhobho ephambili yothungelwano lwegesi yendalo yasezidolophini kunye nobubanzi obusuka kwi-DN1200 ukuya kwi-DN2000, ukufezekisa izahlulo zokhuseleko ngexesha lokugcinwa kwemibhobho kunye noqhagamshelo lwesebe, ukuphepha ukuphuma kwegesi enkulu. Kwi-atmospheric kunye ne-vacuum distillation units kunye ne-catalytic cracking units kushishino lwepetrochemical, imibhobho ephambili yokuthutha i-oyile ekrwada kunye neemveliso ze-oyile esulungekisiweyo ezinobubanzi obungaphezulu kwe-DN1000 kufuneka zitshintshe rhoqo iinkqubo okanye zikwahlule izixhobo.

Iimpawu zabo zokuvula kunye nokuvala ngokukhawuleza kunokunciphisa ixesha lokuphazamiseka kwemveliso. Kwiinkqubo ezimanzi ze-desulfurization/denitrification yeshishini lamandla, ifanelekile kwimibhobho yerhasi yombane engundoqo enobubanzi be-DN1500 okanye ngaphezulu, kwaye inokwahlula igesi yobushushu obuphezulu (enokumelana nobushushu ukuya kuthi ga kwi-300℃) ngexesha lokugcinwa kwe-reactor. Inkqubo yokususa uthuli olomileyo lwerhasi yesithando somlilo kwishishini lesinyithi ifuna ukuba imibhobho yokuhanjiswa kwerhasi enobubanzi obuyi-DN1200 nangaphezulu imelane nokhukuliseko losasazo oluqulathe uthuli. Isakhiwo sayo sesinyithi sokutywina esiqinileyo sinokusebenza ngokuzinzileyo ixesha elide.

Njengomvelisi oneminyaka engama-20 ubudala weevalvu ze-metallurgical (i-Electric Blind Valve), i-Jinbin Valves ibonelela abathengi ngezisombululo zokulawula ulwelo oluphezulu kunye nenkonzo enye. Ukuba unayo nayiphi na imibuzo enxulumeneyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24!
