Umahluko phakathi kweevalvu zebhola zeplastiki kunye neevalvu zebhabhathane zeplastiki kubunjineli behotele…

Ivalve yebhola yeplastiki yenziwe ngevalve yebhola yeplastiki yePVC. Iivalve zebhola zeplastiki kunye ne-pvc zebhola zebhola zifanelekile ukungenelela kweendaba ezinobungozi kwinkqubo yokuthutha. Ubunzima bokukhanya kunye nokumelana nokugqwala okunamandla. Iivalvu zebhola zeplastiki zepneumatic 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, ityuwa yamanzi 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 ineengenelo zokuxhathisa okuqinileyo, ukuxhathisa ukunxiba, ubunzima bomzimba wevalvu, kunye noluhlu olubanzi lwezicelo. Isakhiwo somzimba we-valve samkela uhlobo oluphakathi, olulula ukuchithwa kunye nokulula ukulugcina. Iwafanele amanzi, umoya, ioyile, 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, imibhobho yogutyulo lwelindle, i-brine kunye neenkqubo zemibhobho yamanzi 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 kuzo zombini iziphelo, ezilungele ukuchithwa kunye nokugcinwa, ukuxhatshazwa kokugqoka, ukuchithwa ngokulula, 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 kwiintlobo zemibhobho, kunye noluhlu olubanzi lwezicelo.
