Xa ukhetha isisombululo esinokuthenjwa, esifanelekileyo sokulawula ukuqhubela phambili kwezicelo zophuhliso okanye zikamasipala,I-rabeber yokuhlala i-valveslukhetho oludumileyo. Kwabizwa ngokuba yi-NRS (i-STATE) yesango okanye i-F4 / F5 / F5 yesango, ezi valve ziyilelwe ukulawula ukuqhutywa kwamanzi kwiindawo ezahlukeneyo. Kweli nqaku, siza kuphonononga izibonelelo kunye neempawu ze-valls zerabha kwaye kutheni ziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yolawulo lwamanzi.
I-rabber yokutywina yesango isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokusebenza kwabo okuphezulu kunye nolwakhiwo oluhlala ixesha elide. Isitulo serabha ngaphakathi kwivalini ibonelela ngetywina eliqinileyo esangweni, linceda ukuthintela ukuvuza nokuqinisekisa indlela ethembekileyo yokuvala. Oku kwenza ukuba i-raber yathulwa isango le-valves efanelekileyo kwizicelo apho itywina eliqinileyo libalulekile, njengezityalo zonyango lwamanzi, iinkqubo zamanzi amdaka kunye namaziko okuqhuba kwamachiza. Ukongeza, i-NRS ye-nste ye-valve ifihliweyo kulula ukuyisebenzisa kwaye ilondoloze, isenze isisombululo esisebenzayo sayo nayiphi na inkqubo yokulawulwa kwamanzi.
Esona sibonelelo siphambili se-vallber eshedli yesango kukukwazi kwabo ukuphatha iintlobo ezahlukeneyo zolwelo kunye neemeko zokusebenza. Nokuba ngamanzi, amanzi amdaka, imichiza etyibilika okanye imichiza eguqukayo, irabha yodwa yerabha inokulawula ngempumelelo ukuhamba kwezi zinto ngaphandle kokusebenza kakuhle okanye ukuthembeka. Oku kuphumelela kwerabenzi kwenza i-rober i-valves yotshintsho lweenjineli kunye nabaqhubi abafuna isisombululo esinokuthenjwa nesibethelayo sokuhlangabezana neemfuno zabo ezithile.
Ukongeza kwintsebenzo yabo ebalaseleyo yokutywina kunye nokungahambi kakuhle, irabha yodwa yerabha yaziwa ngeentsini zabo ezinde kunye neemfuno ezincinci. Izihlalo ze-rabber zerabha kunye namasango zenzelwe ukumelana neengqolowa zokuqhubeka nokusetyenziswa kweekhemikhali, zisenza ukhetho oluqinileyo nolomeleleyo lwezicelo zolawulo olulawulayo. Ngofakelo olufanelekileyo kunye nokulungiswa rhoqo, irabha yodwa isango inokubonelela iminyaka yokusebenza ngokukhululekileyo, ukunciphisa iindleko zexesha kunye nezixhobo zolondolozo kunye nomasipala.
Kwisishwankathelo, irabha yodwa isango, ekwabizwa ngokuba yi-valve yesango ye-NRS okanye i-F4 / F5 ye-valves, yindawo yesango elibalulekileyo kuyo nayiphi na inkqubo yolawulo olubalaseleyo, i-proceling plation. Xa sele ithengisiwe ngokufanelekileyo, irabha yothungelwano lwerabha linokutsala umnxeba uluhlu lwamashishini kunye nokusebenza, ukubonelela ngezisombululo ezinolwazi oluthembekileyo, zokulawula ukuhamba okuthembekileyo kwiimeko ezahlukeneyo zokusebenza kunye neemeko zokusebenza. Ngoyilo lwayo esebenzayo kunye nolondolozo lolondolozo, irabha yolondolozo yerabha ye-valves lukhetho olubalaseleyo lwamaziko emizi-mveliso kunye noomasipala abafuna isisombululo esithembekileyo nesibethekayo.
Ngaphandle koko, i-valve ye-TWSve, yazi njenge-tiagin talin willand i-valve co., i-LTD, yitendeti ye-Elastic Advack Shutely Valve,i-bitch ye-flanges yebhabhathane,, i-flange ivutha yebhabhathane e-ectcerfly,ivalve esemthethweni, i-wante cen yeplate yokutshekisha, y-strainer njalo njalo. Ukuba unomdla kwezi valve, nceda ukhululeke ukunxibelelana nathi. Enkosi kakhulu!
IXESHA LOKUQALA: I-DEC-13 ukuya ku-2003
