IIMPAWU ZENKONZO YOKUSEBENZA
Kwimeko yolondolozo, kuyinyani ukuba olu hlobo lwevalve lubalwa langaphantsi kunalo naluphi na olunye uhlobo, kodwa ivelufa inezinto ezithile eziluncedo ngolu hlobo lulandelayo:
1. Ubomi obusebenzayo buqinisekisiwe.
2.Kukho ingono yegrisi kuyo yonke imvalo yentsimbi evaliweyo phantsi kwemveliso yangoku ukuqinisekisa ukuthambisa ngokuchanekileyo kwidyokhwe.
Imisonto esiqwini kulo lonke uhlobo lweentsimbi zetywina kufuneka zigcinwe zicocekile ukuba kunokwenzeka kwaye zithanjiswe ngamaxesha ngamaxesha ngamafutha aphezulu obushushu.
Kuyacetyiswa ukuba ulondolozo lokuthintela kufuneka lwenziwe ubuncinci rhoqo kwiinyanga ezintathu.
Ulondolozo lubaluleke ngokukodwa xa ivelufa iqeshelwe ukusetyenziswa kobushushu obuphezulu xa kunokwenzeka ukuba kubalulekile ukusebenzisa igrisi yohlobo lobushushu obuphezulu.
Ngeli xesha, kuyinqweneleka ukuba ivelufa iqhutywe ivuliwe ukuya kuvalwa, kwaye ngokuchaseneyo.
UKUKHETHWA KWEVALVE
Njengesikhokelo ngokubanzi kukhetho lwevalve olulungele usetyenziso oluthile, ivelufa yesango kufuneka isetyenziselwe ubukhulu becala umphunga oxineneyo ophantsi okanye ophakathi, imigca yokulandela umkhondo womphunga, okanye ezinye iinkonzo ezinje ngokudlulisa ubushushu. Ivaluva yeglobhu kufuneka ikhethelwe ubushushu obuphakathi okanye obuphezulu, apho ukubekwa kweenqanawa kungabandakanyeka kwingxaki yokhuseleko. Isetyenziselwa ukuphatha imithombo yeendaba eyityhefu okanye yokuqhushumba kwaye kwimeko nganye apho kunokubakho ingxaki kummiselo wokuhamba.
Kufuneka kuqatshelwe ukuba sinevalve eyenzelwe ngokukodwa apho ukubaleka okungafunekiyo kwigesi okanye ulwelo kuthintelwe ngokupheleleyo. Kwivelufa, ukupakishwa kwesiqu esiqhelekileyo kufakwa inwebu yentsimbi eguqukayo apho zonke iindlela ezivuzayo ezinokubakho ngesiqu okanye ngokudibeneyo komzimba / webonnet.
Iiyunithi zokuvuthwa ezifakwe kule valve zavavanywa kumjikelo wobomi ukuya kwintshabalalo, okukhokelela kwiziphumo zovavanyo olwanelisayo lokuhlangabezana nexesha lobomi, ubushushu, kunye neemfuno zoxinzelelo lwe-ASME B16.34.
