Njengomlinganiso wenani lokufakelwa kweplastiki kunye nokubanda kwamanzi kunye nezicelo zobunjineli bobuchwephesha ziyaqhubeka nokwanda, ukulawulwa komgangatho weevalve zeplastiki kwiinkqubo zokulinganisa zeplastiki kuya kusilela ngakumbi nangakumbi.
Ngenxa yobuninzi bobunzima bokukhanya, ukumelana nokungakhathali, unxibelelwano oluhlanganisiweyo kunye nemibhobho yeplastiki, kunye neevila zeplastiki ezisetyenziswayo kunye nokufudumeza) kunye nolwelo lwamanzi. Kwinkqubo yokubhoboza, iinjongo zayo zokusebenza azifanelwanga ngamanye amava. Okwangoku, kwimveliso kunye nokusetyenziswa kweeValk zePlakithi zaseKhaya, akukho ndlela inokuthenjwa yokulawula, ikhokelela kumgangatho we-valve ongenanga noncedo lwamanzi, obangela ukuvalwa kwezicelo zobunjineli. Inzulu, yenze ingxelo yokuba i-valves zeplastiki ayinakusetyenziswa, echaphazela uphuhliso luphela kwimibhobho yeplasitiki. Imigangatho yelizwe lam lelizwe leevalves zeplastiki kwinkqubo yokwenziwa, kwaye imigangatho yemveliso kunye nendlela yenziwa ngokwemigangatho yehlabathi.
Kwilizwe jikelele, iindidi zeevali zeplastiki ikakhulu zibandakanyaI-MF yeBhola yeBhola yeBhola, Ibhotile yebhabhathane, Jonga iiValves, i-dialveragm, i-valve yesango kunye nevalve evaliwe. Eyona fomu iphambili yesakhiwo ziindlela ezimbini, iindlela ezintathu neecawa ezininzi. Izinto ezingafunekiyo ikakhulu i-ABS, i-PVC-U, pvc- C, PB, PV, PP kunye nePVDF njl.
Kwimigangatho yamazwe ngamazwe kwiimveliso zeVenkile yePlastiki, eyokuqala kukufuna izixhobo ezingafunekiyo ezisetyenziselwa ukuveliswa kweeValve. Umenzi wezinto ezingafunekiyo kufuneka abe ne-curve yokusilela ekuphumezeni ezihlangabezana nemigangatho yeemveliso zeplastiki [1]; Kwangelo xesha, uvavanyo lokutywina kunye ne-valve yevalve yeevumba zeplastiki ezifunekayo. Uvavanyo, uvavanyo lwendlela yokusebenza yexesha elide ye-valve ebalulekileyo, uvavanyo lwamandla oludindlayo kunye neTorque oSebenzayo bonke abamiweyo, kunye nobomi benkonzo yoyilo lwe-valve esetyenzisiweyo yeminyaka engama-25.
