Iindidi zeevalvu zeplastiki ehlabathini ikakhulu ziquka ivalve yebhola, ivalve yebhabhathane, ivalve yokukhangela, ivalve yediaphragm, ivalve yesango kunye neglowubhu.Iifom zesakhiwo ziquka ikakhulu iindlela ezimbini, iindlela ezintathu kunye neevalve zeendlela ezininzi.Izinto ekrwada ikakhulu ziquka ABS, PVC-U, PVC-C, PB, PE, PP kunye PVDF.
Kwimigangatho yamazwe ngamazwe yeemveliso zevalvu zeplastiki, okokuqala, izinto ezisetyenziselwa ukuveliswa kweevalvu ziyafuneka.Abavelisi beevalvu kunye nezinto zabo ezikrwada kufuneka babe neegophe zokusilela kwe-creep ezihlangabezana nemigangatho yemveliso yombhobho weplastiki;Kwangaxeshanye, uvavanyo lokutywina, uvavanyo lomzimba wevalvu, uvavanyo lwexesha elide lokusebenza, uvavanyo lwamandla okukhathala kunye ne-torque yokusebenza yevalve yeplastiki ichaziwe, kwaye ubomi benkonzo yoyilo lwevalve yeplastiki esetyenziselwa ukuthutha ulwelo lweshishini yiminyaka engama-25.
Iivalve zeplastiki azifaki isikali, zinokudibaniswa kunye nemibhobho yeplastiki kwaye ibe nobomi obude benkonzo.Iivalvu zeplastiki zineenzuzo ekusebenziseni kwiinkqubo zemibhobho yeplastiki ukwenzela unikezelo lwamanzi (ingakumbi amanzi ashushu kunye nokufudumeza) kunye nolunye ulwelo lwamashishini olungenako ukuhambelana nezinye iivalvu.
umfanekiso
Iindidi zeevalvu zeplastiki ikakhulu ziquka ivalve yebhola, ivalve yebhabhathane, ivalve yokukhangela, ivalve yediaphragm, ivalve yesango kunye neglowubhu;Iifom zesakhiwo ziquka ikakhulu iindlela ezimbini, iindlela ezintathu kunye neevalve zeendlela ezininzi;Izinto eziphathekayo ziquka i-ABS, i-PVC-U, i-PVC-C, i-PB, i-PE, i-PP kunye ne-PVDF.

umfanekiso
·PVCivalve yebhola(indlela-mbini/indlela-ntathu)
Ivalve yebhola yePVC isetyenziswa ikakhulu ukusika okanye ukudibanisa okuphakathi kumbhobho, kunye nokulawula nokulawula ulwelo.Xa kuthelekiswa nezinye iivalvu, inokumelana nolwelo oluncinci kwaye ivalve yebhola inokumelana nolwelo oluncinci phakathi kwazo zonke iivalvu.Ukongeza, ivalve yebhola ye-UPVC yimveliso yevalvu yebhola ephuhliswe ngokweemfuno zolwelo lwemibhobho eyonakalisayo.
Mbini
umfanekiso
·PVC butterfly valve
Ivalve yebhabhathane yePlastiki inoxhathiso olomeleleyo lwe-corrosion, uluhlu olubanzi lwesicelo, ukuxhathisa ukunxiba, ukuchithwa lula kunye nokugcinwa okulula.Ulwelo olusebenzayo: amanzi, umoya, i-oyile, ulwelo lwekhemikhali elonakalisayo.Isakhiwo somzimba wevalve samkela uhlobo lomgca osembindini.Ivalve yeplastiki yebhabhathane kulula ukuyisebenzisa, ngokutywinwa okuqinileyo kunye nobomi benkonzo ende;Ingasetyenziselwa ukunqumla ngokukhawuleza okanye ukulungelelanisa ukuhamba.Ifanelekile kwizihlandlo apho ukutywinwa okuthembekileyo kunye neempawu zokulawula ezilungileyo zifunekayo.
