Ukwandisa ngokufanelekileyo ubomi benkonzo yeIivalvu zebhola zePVC, kuyimfuneko ukudibanisa ukusebenza okusemgangathweni, ukugcinwa rhoqo, kunye nemilinganiselo yokugcinwa okujoliswe kuyo. Iindlela ezikhethekileyo zezi zilandelayo:
Ukufakela okusemgangathweni kunye nokusebenza
1. Iimfuno zofakelo
(a) Isalathiso kunye nendawo: Ukudadaiivalve zebholakufuneka ifakwe ngokuthe tye ukugcina i-axis yenqanaba lebhola kunye nokwandisa ukusebenza kokutywina usebenzisa ubunzima babo; Iivalvu zebhola ezikhethekileyo (ezifana nezo zinezixhobo zokutshiza) kufuneka zifakwe ngokungqongqo ngokwendlela yokuhamba kwesixhobo.
(b) Ukucocwa kwemibhobho: Susa ngokucokisekileyo i-welding slag kunye nokungcola ngaphakathi kombhobho phambi kofakelo ukunqanda ukonakalisa ingqukuva okanye umphezulu wokutywina.
(c) Indlela yokudibanisa: Uqhagamshelo lwe-Flange lufuna ukuqiniswa okufanayo kweebholithi kwi-torque eqhelekileyo; Thatha amanyathelo okupholisa ukukhusela iindawo ezingaphakathi kwevalve ngexesha le-welding.
2. Imigangatho yokusebenza
(a) Ukulawulwa kweTorque: Gwema i-torque egqithisileyo ngexesha lokusebenza ngesandla, kunye nombane / i-pneumatic drive kufuneka ihambelane ne-torque yokuyila.
(b) Isantya sokutshintsha: Vula ngokucothayo kwaye uvale isivalo ukunqanda impembelelo yehamile yamanzi ekonakaliseni umbhobho okanye ubume bokutywina.
(c) Umsebenzi oqhelekileyo: Iivalvu ezihleli ixesha elide zingasebenzi kufuneka zivulwe kwaye zivalwe rhoqo emva kweenyanga ezi-3 ukuthintela undoqo wevalvu ukuba ungabambeleli kwisitulo sevalve.
Ukugcinwa okucwangcisiweyo kunye nokugcinwa
1. Ukucoca kunye noHlolo
(a) Coca uthuli olungaphezulu kunye namabala e-oyile omzimba wevalvu rhoqo ngenyanga, usebenzisa iiarhente zokucoca ezingathathi ntweni ukunqanda ukubola kwezinto zePVC.
(b) Jonga imfezeko yomphezulu wokutywina uze uphande ngoko nangoko nakuphi na ukuvuza (okufana neringi zokutywina ezigugayo okanye ukuvaleka kwezinto zangaphandle).
2. Ulawulo lokuthambisa
(a) Yongeza rhoqo igrisi ehambelana ne-PVC yokuthambisa (efana negrisi yesilicone) kwi-valve stem nut ukunciphisa ukuxhathisa.
(b) Amaxesha okuthambisa ahlengahlengiswa ngokwemeko-bume yokusetyenziswa: kanye qho kwiinyanga ezi-2 kwindawo efumileyo kwaye kanye ngekota kwindawo ezomileyo.
3. Ukugcinwa kwetywina
(a) Ukutshintsha rhoqo amakhonkco okutywina e-EPDM/FPM (kucetyiswa rhoqo emva kweminyaka emi-2-3 okanye ngokusekwe ekunxityweni nasekukraleni).
(b) Coca igroove yesitulo sevalve ngexesha lokuqhawula ukuqinisekisa ukuba umsesane omtsha wokutywina ufakwe ngaphandle kokuphazamiseka.
Ukuthintela iimpazamo kunye nokuphatha
1. Uthintelo lomhlwa kunye nomhlwa
(a) Xa ujongano lunerusi, sebenzisa iviniga okanye i-agent yokukhulula ukuyisusa kwiimeko ezincinci; Isigulo esinzima sifuna ukutshintshwa kwevalvu.
(b) Yongeza izigqubuthelo ezikhuselayo okanye ufake ipeyinti enqanda umhlwa kwindawo enomhlwa.
2. Ukuphatha amakhadi ancamatheleyo
Xa uxinanisa kancinane, zama ukusebenzisa isikrufu ukuze uncede ekujikeni isiqu sevalvu;
Xa ubambeke kakhulu, sebenzisa isivuthelo somoya oshushu ukufudumeza umzimba wevalvu ekuhlaleni (≤ 60 ℃), kwaye usebenzise umgaqo wokwandiswa kwe-thermal kunye nokucutheka ukukhulula undoqo wevalve.
