Kev Paub Txog PE Yeeb Nkab Valve Kev Sib Txuas

Lub rooj vag tooj liab feem ntau yog flanged, thiab txoj kev yog tib yam li "flange valve". Yog tias koj ntsib lub rooj vag valve nrog cov hlau sab hauv (feem ntau yog ib txoj kab uas hla me me), tom qab ntawd nruab cov hlau sab nraud ncaj qha rau ntawm lub raj xa dej, thiab cov txheej txheem kev teeb tsa yog tib yam li "screw valve"; Cov ntsia hlau valve feem ntau yog cov hlau sab nraud, yog li koj yuav tsum tau nruab ib lub xov hlau sab hauv ncaj qha rau ntawm lub raj xa dej, thiab cov hlau sab hauv txuas ncaj qha mus rau PE yeeb nkab los ntawm kub yaj, thiab tom qab ntawd screwed rau lub hau ntsaws valve; vim lub flange valve muaj nws tus kheej txoj kev ntawm lub valve lub cev. flange, tom qab ntawd koj tsuas yog yuav tsum tau ntxiv lub nplhaib txhawb nqa thiab lub flange ntawm cov ntsiab lus sib thooj rau PE yeeb nkab, thiab koj tuaj yeem nruab nws. Lub nplhaib txhawb nqa xav tau kev sib txuas kub yaj, thiab flange daim yog bolted rau flange valve.
