Njengoba i-valve yebhola ivamise ukusebenzisa irabha, inayiloni kanye ne-polytetrafluoroethylene njengendandatho yokuvala isihlalo, izinga lokushisa layo lokusetshenziswa lilinganiselwe yindandatho yokuvala isihlalo.Umsebenzi wokusika we-valve yebhola ufezwa ngokucindezela ibhola lensimbi ngokumelene nesihlalo se-valve yepulasitiki ngaphansi kwesenzo se-medium (i-valve yebhola elintantayo).Ngaphansi kwesenzo sengcindezi ethile yokuxhumana, indandatho yokuvala isihlalo se-valve ishintsha ngokunwebeka nangokwepulasitiki kwezinye izindawo.Lokhu kuguqulwa kunganxephezela ukunemba kokukhiqiza kanye nokuqina kwebhola, futhi kuqinisekise ukusebenza kokuvala kwe-valve yebhola.
Ngaphezu kwalokho, njengoba indandatho yokuvala isihlalo se-valve yebhola ngokuvamile yenziwe ngepulasitiki, lapho ukhetha ukwakheka nokusebenza kwe-valve yebhola, kuyadingeka ukucabangela ukumelana nomlilo nokumelana nomlilo we-valve yebhola, ikakhulukazi ku-petroleum, amakhemikhali, i-metallurgical kanye neminye imikhakha, emithonjeni evuthayo neqhumayo I-valve yebhola isetshenziswa ohlelweni lwemishini kanye nepayipi, futhi ukunakekelwa okwengeziwe kufanele kukhokhwe ukumelana nomlilo nokuvimbela umlilo.
Ngokuvamile, ekulungisweni kwezikhundla ezimbili, ukusebenza kokuvala okuqinile, udaka, ukugqoka, isiteshi sokubopha, isenzo sokuvula nokuvala ngokushesha (1/4 ukuvula nokuvala), ukusika kwengcindezi ephezulu (umehluko omkhulu wengcindezi), umsindo ophansi, i-cavitation kanye ukuhwamuka, Ezinhlelweni zamapayipi anenani elincane lokuvuza emkhathini, i-torque encane yokusebenza kanye nokumelana noketshezi oluncane, ama-valve ebhola ayanconywa.
Amavalvu ebhola nawo afaneleka kumasistimu amapayipi anesakhiwo sokukhanya, i-low pressure cut-off (umehluko omncane wengcindezi), kanye nemidiya egqwalayo.
Ama-valve ebhola angasetshenziswa futhi kumishini yokushisa ephansi (cryogenic) kanye nezinhlelo zamapayipi.
Ohlelweni lwamapayipi omoya-mpilo embonini ye-metallurgical, ama-valve ebhola athole ukwelashwa okuqinile kokukhipha amafutha ayadingeka.
Lapho ulayini oyinhloko wepayipi likawoyela kanye nepayipi legesi udinga ukugqitshwa ngaphansi komhlaba, amavalvu amabhola ashiselwe anobubanzi obugcwele ayadingeka.
Lapho kulungiswa ukusebenza kuyadingeka, i-valve yebhola enesakhiwo esikhethekile esinokuvulwa okumise okwe-V kufanele kukhethwe.
Ku-petroleum, i-petrochemical, amakhemikhali, amandla kagesi, kanye nokwakhiwa kwedolobha, ama-valve ebhola avaliwe ensimbi ukuya kwensimbi angasetshenziselwa amasistimu amapayipi anamazinga okushisa asebenzayo angaphezu kuka-200 ° C.
I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,Ivalve yesango,Hlola Valve,I-Globe Vavlve,I-Y-Strainers,I-Acurator kagesi,Ama-Acurator Womoya.
