Njengoba ivalvu yebhola ivame ukusebenzisa irabha, i-nylon kanye ne-polytetrafluoroethylene njengezinto zokuvala isihlalo, izinga lokushisa lokusetshenziswa kwayo linqunyelwe yizinto zokuvala isihlalo. Umsebenzi wokunqunywa kwevalvu yebhola ufezwa ngokucindezela ibhola lensimbi esihlalweni sevalvu yepulasitiki ngaphansi kwesenzo se-medium (ivalvu yebhola entantayo). Ngaphansi kwesenzo sokucindezela okuthile kokuxhumana, indandatho yokuvala isihlalo sevalvu iyaguquguquka ngokunwebeka nangokuplastiki kwezinye izindawo. Lokhu kuguquka kungabuyisela ukunemba kokukhiqiza kanye nokuqina kobuso bebhola, futhi kuqinisekise ukusebenza kokuvala kwevalvu yebhola.
Ngaphezu kwalokho, njengoba indandatho yokuvala isihlalo se-valve yebhola ivame ukwenziwa ngepulasitiki, lapho ukhetha isakhiwo kanye nokusebenza kwe-valve yebhola, kubalulekile ukucabangela ukumelana nomlilo kanye nokumelana nomlilo kwe-valve yebhola, ikakhulukazi emkhakheni we-petroleum, amakhemikhali, we-metallurgical kanye neminye, ezindaweni ezivuthayo neziqhumayo. I-valve yebhola isetshenziswa ohlelweni lwemishini kanye nephayiphi, futhi kufanele kuqashelwe kakhulu ukumelana nomlilo kanye nokuvimbela umlilo.
Ngokuvamile, ekulungisweni kwezikhundla ezimbili, ukusebenza okuqinile kokuvala, udaka, ukuguguleka, isiteshi sokugoqa, isenzo sokuvula nokuvala okusheshayo (ukuvula nokuvala okungu-1/4), ukunqamula ukucindezela okuphezulu (umehluko omkhulu wokucindezela), umsindo ophansi, ukugoba kanye nokuhwamuka, Ezinhlelweni zamapayipi ezinenani elincane lokuvuza emoyeni, i-torque encane yokusebenza kanye nokumelana okuncane koketshezi, kunconywa ama-ball valve.
Ama-valve ebhola nawo afaneleka ezinhlelweni zamapayipi anesakhiwo esilula, ukunqunywa komfutho ophansi (umehluko omncane womfutho), kanye nemidiya ebolile.
Ama-ball valve angasetshenziswa nakumadivayisi okushisa okuphansi (cryogenic) kanye nezinhlelo zamapayipi.
Kuhlelo lwamapayipi e-oxygen embonini yensimbi, kudingeka ama-ball valve asebethole ukwelashwa okuqinile kokususa amafutha.
Uma umugqa oyinhloko epayipini likawoyela kanye nepayipi legesi udinga ukugqitshwa ngaphansi komhlaba, kudingeka amavalvu ebhola ahlanganisiwe anobubanzi obugcwele.
Uma kudingeka ukulungisa ukusebenza, kufanele kukhethwe i-valve yebhola enesakhiwo esikhethekile esinokuvulwa okufana no-V.
Ku-petroleum, petrochemical, chemical, kagesi, kanye nokwakhiwa kwedolobha, ama-valve ebhola avaliwe kusukela kwensimbi kuya kwensimbi angasetshenziswa ezinhlelweni zamapayipi anezinga lokushisa lokusebenza elingaphezu kuka-200°C.
INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,I-Valve yeSango,Hlola i-Valve,I-Globe Vavlve,Izihlungi ze-Y,I-Acurator kagesi,Ama-Acurators omoya.
