Ububanzi bokuhlola
Uma zingekho ezinye izinto ezengeziwe ezishiwo kwinkontileka ye-oda, ukuhlolwa komthengi kufanele kukhawulelwe kulokhu okulandelayo:
a) Ngokuhambisana nemithetho yenkontileka ye-oda, sebenzisa amathuluzi okuhlola angonakalisi nezindlela ukuze uhlole amavalvu phakathi nenqubo yokuhlanganisa.
b) Ukuhlolwa okubonakalayo kokusakazwa kwamavalvu kufanele kuhambisane ne-JB/T 7929.
c) Ukuhlolwa kwengcindezi "Okuphoqelekile" kanye "nokuzikhethela".
d) Okunye ukuhlola okwengeziwe.
e) Buyekeza amarekhodi okucubungula kanye namarekhodi okuhlola angonakali (okuhlanganisa namarekhodi okuhlola ama-radiographic acacisiwe).
Qaphela: Konke ukuhlolwa kufanele kwenziwe ngokuhambisana nezinqubo ezibhaliwe ezisungulwe kumazinga ahambisanayo.
Ukuhlola
Umkhiqizi wamavalvu kufanele enze ukuhlola okubonakalayo kukho konke ukusakazwa kwemizimba yamavalvu, amabhonethi nezinto zokuvala ukuze kuvikelwe ukuthobela kwayo i-JB/T 7929.
Umkhiqizi wamavalvu kufanele ahlole i-valve ngayinye ukuze aqinisekise ukuhambisana namazinga asebenzayo kanye namazinga omkhiqizo ahlobene.
Izidingo ezijwayelekile zokuhlolwa kwengcindezi
1. Kumavalvu anesakhiwo esikhethekile avumela ugrisi ovala uphawu oluphuthumayo ukuthi ajovwe endaweni yokuvala noma ezingxenyeni zokupakisha (ngaphandle kwamavalvu epulaki agcotshiwe), uhlelo lomjovo kufanele lungabi nalutho futhi lungasebenzi ngesikhathi sokuhlolwa.
2. Uma uhlola ngoketshezi, qiniseka ukuthi umoya we-cavity ukhishiwe.
3. Ngaphambi kokwenza ukuhlolwa kwegobolondo le-valve, i-valve akumele ipendwe noma imbozwe nganoma yiziphi izimbobo ezingafihla ukonakala kwendawo.I-Phosphating noma ukwelapha ngamakhemikhali okufanayo okusetshenziselwa ukuvikela indawo yevalvu kuvunyelwe, kodwa akumele kuvale iziphambeko njengokuvuza, izimbobo zomoya noma amabhamuza.
4. Lapho wenza izivivinyo zokuvala ama-valve esango, amapulaki namavalvu ebhola, imbobo yomzimba phakathi kwebhonethi nendawo yokuvala kufanele igcwaliswe ngesisetshenziswa.Khona-ke kufanele usebenzise ingcindezi kuyo ukuze uhlole ingcindezi futhi ugweme ukugcwaliswa kancane kancane kwezingxenye ezingenhla nge-medium nengcindezi ngesikhathi sokuhlolwa, kuyilapho futhi ugwema ukuvuza kwe-seal.
5. Lapho wenza ukuhlolwa kokuvala uphawu, akukho mandla angaphandle okufanele asetshenziswe emikhawulweni yokuphela kwe-valve enomthelela ekuvuzeni kwendawo yokuvala.I-torque esebenzayo esetshenziselwa ukuvala i-valve akufanele idlule isikhathi sokuvala samandla (i-torque) yomklamo we-valve.
I-EC ihlinzeka ngezinsizakalo zokuhlola ama-valve ezichwepheshile kulo lonke elaseChina.Xhumana nathi uma udinga ukuhlola ngokunembile ikhwalithi yemikhiqizo yakho.
