Ukuhlolwa ngaphambi kokufakwa kwe-valve
① Hlola ngokucophelela ukuthi i-i-valveimodeli kanye nokucaciswa kuhlangabezana nezidingo zomdwebo.
② Hlola ukuthi isiqu se-valve nediski ye-valve ingavulwa kalula yini, nokuthi ibambekile noma itshekile.
③ Hlola ukuthi i-valve yonakele yini nokuthi intambo ye-valve enentambo ilungile futhi iphelele.
④ Hlola ukuthi ingabe inhlanganisela yesihlalo se-valve nomzimba we-valve iqinile, ukuxhumana phakathi kwe-disc ye-valve nesihlalo se-valve, isembozo se-valve nomzimba we-valve, nesiqu se-valve kanye ne-valve disc.
⑤ Hlola ukuthi i-gasket ye-valve, ukupakisha kanye nezinsimbi (ama-bolts) zifanelekile yini izidingo zendlela yokusebenza.
⑥ I-valve yokukhulula ingcindezi endala noma isikhathi eside kufanele ihlakazwe, futhi uthuli, isihlabathi kanye nezinye izibi kufanele kuhlanzwe ngamanzi.
⑦ Susa isembozo sembobo, hlola izinga lokuvala, futhi i-valve disc kumele ivalwe ngokuqinile.
Ukuhlolwa kokucindezela kwe-valve
Ama-valve anomfutho ophansi, we-medium-pressure kanye ne-high-pressure test kufanele ahlolwe amandla kanye nokuhlolwa kokuqina, futhi ama-valve ensimbi ye-alloy nawo kufanele ahlaziywe nge-spectral yegobolondo ngayinye, futhi impahla kufanele ibuyekezwe.
1. Ukuhlolwa kwamandla e-valve
Ukuhlolwa kwamandla kwe-valve ukuhlola i-valve esimweni esivulekile ukuhlola ukuvuza endaweni engaphandle ye-valve.Kumavalvu ane-PN≤32MPa, ukucindezela kokuhlola izikhathi ezingu-1.5 kunokucindezela okungokomfanekiso, isikhathi sokuhlola singekho ngaphansi kuka-5min, futhi akukho ukuvuza kugobolondo nendlala yokupakisha okufanele ifaneleke.
2. Ukuhlolwa kokuqina kwe-valve
Ukuhlolwa kwenziwa ivalvu ivalwe ngokugcwele ukuze kubhekwe ukuthi akukho yini ukuvuza endaweni yokuvala yevalvu.Ingcindezi yokuhlola, ngaphandle kwamavalvu ovemvane, amavalvu okuhlola, ama-valve aphansi, nama-throttle valves, ngokuvamile kufanele kwenziwe ngokucindezela okulinganiselwe.Uma ingcindezi yokusebenza isetshenziswa, ingabuye ihlolwe nge-1.25 izikhathi zokucindezela kokusebenza, futhi ifaneleka uma indawo yokuvala idiski ye-valve ingavuzi.
Mayelana ne-CVG Valve
I-CVG Valveikhethekile ekuthuthukiseni nasekukhiqizeni ama-valve ovemvane anengcindezi ephansi naphakathi, amavalvu esango, ama-valve amabhola, ama-valve okuhlola, izinhlobo zamavalvu okusebenza, ama-valve okuklama akhethekile, ama-valve enziwe ngokwezifiso kanye namajoyinti okudiliza amapayipi.Futhi iyisizinda sokukhiqiza esiyinhloko samavalvu evemvane anosayizi omkhulu ukusuka ku-DN 50 kuya ku-4500 mm.
Imikhiqizo eyinhloko yilezi:
-Ama-valve evemvane ane-eccentric ephindwe kabili
-Ama-valve evemvane e-eccentric kathathu
-Ama-valve uvemvane anerabha
-Ama-valve ovemvane ohlobo lwe-wafer
-Ama-valve ovemvane okulawula i-hydraulic
-Ama-valve esango uchungechunge
-Ama-valve ebhola e-Eccentric
-Ama-valve okuhlola okulawula i-hydraulicnjll.
