Ivalve yebhola yeplastiki yenziwe ngevalve yebhola yeplastiki yePVC.Iivalve zebhola zeplastiki kunye ne-pvc zebhola zebhola zifanelekile ukungenelela kweendaba ezinobungozi kwinkqubo yokuthutha.Ubunzima obulula kunye nokumelana nokugqwala okunamandla.Iivalvu zebhola zeplastiki ze-pneumatic kunye ne-pvc zebhola ze-pneumatic zebhola zisetyenziswa kwiindawo ezininzi, ezifana namanzi ahlambulukileyo ngokubanzi kunye neenkqubo zemibhobho yamanzi okusela akrwada, i-drainage kunye neenkqubo zemibhobho yogutyulo, amanzi etyuwa kunye neenkqubo zemibhobho yamanzi olwandle, i-acid-base kunye neenkqubo zesisombululo sekhemikhali, njl. , Umgangatho wamkelwa luninzi lwabasebenzisi.
(1) Inkangeleko idibene kwaye intle.
(2) Umzimba ulula ngobunzima kwaye kulula ukuyifaka.
(3) Izinto eziphathekayo zicocekile kwaye azikho ityhefu.
(4) Ukuxhathisa okuqinileyo kwe-corrosion kunye noluhlu olubanzi lwesicelo.
(5) Ukunganxibi, kulula ukuqhaqha, kulula ukuyigcina.
Ivalve yeplastiki yebhabhathane yePVC ineenzuzo zokuxhathisa okuqinileyo, ukuxhathisa, ubunzima bomzimba wevalvu, kunye noluhlu olubanzi lwezicelo.Isakhiwo somzimba we-valve sithatha uhlobo lwe-centerline, olulula ukuchithwa kunye nokulula ukulugcina.Iwafanele amanzi, umoya, i-oyile, kunye neekhemikhali ezonakalisayo.ulwelo.Ivalve yebhabhathane yeplastiki yepneumatic inokulungelelanisa ngokuthe ngqo umthamo wokutshintsha ngomoya oxinanisiweyo.Ixhotyiswe nge-valve positioner yokufaka i-4-20mA yesiginali, enokulungelelanisa ukuhamba kweendaba, uxinzelelo, ubushushu kunye nezinye iiparitha.Isetyenziswa ngokubanzi kumanzi acocekileyo kunye nemibhobho yamanzi okusela akrwada.Umgangatho weenkqubo, imibhobho yokuhambisa amanzi amdaka kunye nogutyulo, iinkqubo zemibhobho yamanzi ane-brine kunye namanzi olwandle, isiseko se-asidi kunye neenkqubo zesisombululo sekhemikhali kunye namanye amashishini sele eqatshelwe luninzi lwabasebenzisi.
Iimpawu zevalve yebhabhathane yeplastiki yepneumatic:
1. Izinto eziphathekayo zicocekile kwaye zingenabuthi, isakhiwo esilula, ubungakanani obuncinci, ubunzima obulula, ukusetyenziswa kwezinto eziphantsi, kunye nobukhulu obuncinci bokufaka;
2. Uxhulumaniso lwenziwa ngokudibanisa ama-flanges kwiiphelo zombini, ezilungele ukuchithwa kunye nokugcinwa, ukuxhatshazwa kokugqoka, ukuchithwa kulula, kwaye kulula kwaye kulula ukuyigcina;
3. I-valve ye-butterfly ye-PVC itshintsha ngokukhawuleza, ibuyele kwi-90 degrees, kwaye ine-torque encinci yokuqhuba.
I-4.I-valve ye-butterfly yeplastiki ye-pneumatic inezixhobo ezahlukeneyo zokukhetha ngokweendaba ezahlukeneyo, ezinokumelana nokugqwala okuqinileyo, ubungakanani obuncinci, obufanelekileyo kwiindidi zemibhobho, kunye noluhlu olubanzi lwezicelo.
