Njengezixhobo zokulawula ulwelo, iivalvu zisetyenziswa kakhulu kwiinkqubo zoshishino. Kwiinkqubo ezininzi zemibhobho ezithutha ulwelo olufana nolwelo, iigesi, iipowders, njl.njl., iivalvu zidlala indima ebalulekileyo. Nangona kunjalo, kwezinye iimeko zoshishino ezineemfuno eziphezulu zococeko nokhuseleko, iivalvu ezingafanelekanga zinokubangela iingozi.
1. Imingeni Ejongene NeeValve Kwiindawo Ezifuneka Kakhulu
Kwishishini leekhemikhali, ukuthutha izinto ezibangela ukubola yinto eqhelekileyo. Umgca wemveliso yokutya neziselo kunye neenkqubo zokubonelela ngamanzi uneemfuno eziphezulu kakhulu zokhuseleko kunye nococeko lwemibhobho. Ishishini lezemithi kufuneka lilawule ngokungqongqo umlinganiselo wezinto ezahlukeneyo ezibangela ukubola kwamachiza. Kwezi ndawo, iivalvu eziqhelekileyo zinokuba neentsholongwane, ungcoliseko olunqamlezileyo, ukuqhekeka kwamasuntswana, kunye nokubola kweekhemikhali kukhokelela ekuvuzeni kolwelo. Kwiindawo ezifunwa kakhulu, indlela yokuphepha ezi ngxaki yingxaki ejongene neevalvu.
Ukuze sihlangabezane nemingeni, sidinga ivalvu edibanisa ukusebenza kakuhle kokutywina, ukumelana nokugqwala, kunye nokuqina ukuze kucoceke kakhulu kwaye kukhuseleke iinkqubo zokuhambisa ulwelo. Kwaye ivalvu yebhola yentsimbi engagqwaliyo ihlangabezana ngokugqibeleleyo neemfuno.
2. Yintoni iValve yeBVall yentsimbi engagqwaliyo?
A Ivalvu yeBholaluhlobo lwevalvu esebenzisa ibhola njengento yokuvala. Olu hlobo lwevalvu lunokuqhutywa sisiphatho okanye esinye isixhobo sokuqhuba. Jikelezisa ibhola ngee-degrees ezingama-90 ukuze umngxuma webhola ugqume okanye umi nkqo kumgca ophakathi wetshaneli yomzimba wevalvu, emva koko ivalvu ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo. Kwaye ivalvu yebhola yentsimbi engagqwaliyo yivalvu enomzimba kunye nebhola eyenziwe ngentsimbi engagqwaliyo.
Ihlala iqulathe ibhola yentsimbi engagqwaliyo enomgodi odlulayo, umzimba wevalvu yentsimbi engagqwaliyo, isiqu sevalvu, kunye nesitywini. Ukuhamba kolwelo olwahlukeneyo kumbhobho, njengomoya, umphunga, amanzi, imidiya erhabaxa, udaka, ioyile, igesi yendalo, njl.njl., kunokunqunyulwa, kusasazwe, okanye kutshintshwe ngokujikeleza umongo wevalvu. Kukho ulwahlulo olwahlukeneyo lweevalvu zebhola yentsimbi engagqwaliyo.
