Umgomo wokusebenza kanye nokwakhiwa kanye namaphuzu okufakwa kwe-valve ye-butterfly ehlezi ngerabha

Iivalvu yebhabhathane ehlezi ngerabhauhlobo lwevalvu esebenzisa ipuleti levemvane eliyindilinga njengengxenye yokuvula nokuvala futhi ijikeleza nesiqu sevalvu ukuvula, ukuvala nokulungisa isiteshi soketshezi. Ipuleti levemvane leivalvu yebhabhathane ehlezi ngerabhaifakwe ohlangothini lobubanzi bepayipi. Esiteshini esiyisilinda se-ivalvu yebhabhathane ehlezi ngerabhaumzimba, ipuleti lebhabhathane eliyimilo yediski lijikeleza i-axis, kanti i-engeli yokujikeleza iphakathi kuka-0° no-90°. Uma lijikeleza lifinyelela ku-90°, ivalvu ivuleka ngokuphelele.

Izindawo zokwakha nezokufaka

1. Indawo yokufaka, ukuphakama, kanye nendlela yokungenisa nokuthumela impahla kumele kuhlangabezane nezidingo zomklamo, futhi uxhumano kufanele luqine futhi luqine.

2. Kuzo zonke izinhlobo zamavalvu esandla afakwe epayipini lokushisa, isibambo akufanele sibe phansi.

3. Ukuhlolwa okubonakalayo kumele kwenziwe ngaphambi kokuba ivalvu ifakwe, futhi ipuleti legama levalvu kufanele lihlangabezane nezidingo zezinga lamanje likazwelonke elithi “General Valve Mark” GB12220. Kwivalvu enomfutho wokusebenza omkhulu kune-1.0MPa futhi edlala indima ekunqumeni ipayipi eliyinhloko, ukuhlolwa kwamandla nokusebenza okuqinile kufanele kwenziwe ngaphambi kokufakwa, futhi kuvunyelwe ukusetshenziswa ngemuva kokudlula ukuhlolwa. Ngesikhathi sokuhlolwa kwamandla, ingcindezi yokuhlola iphindwe ka-1.5 kunomfutho ojwayelekile, futhi ubude bayo bungaphansi kwemizuzu emi-5. Indlu yevalvu kanye nokupakisha kufanele kuqinisekiswe ngaphandle kokuvuza. Esivivinyweni sokuqina, ingcindezi yokuhlola iphindwe ka-1.1 kunomfutho ojwayelekile; ingcindezi yokuhlola kufanele ihlangabezane nezidingo zezinga le-GB50243 ngesikhathi sokuhlolwa, futhi ubuso bokuvala idiski yevalvu buqinisekisiwe uma kungekho ukuvuza.

Amaphuzu okukhetha umkhiqizo

1. Amapharamitha okulawula ayinhlokoivalvu yebhabhathane ehlezi ngerabhayizincazelo kanye nobukhulu.

2. Ingasetshenziswa ngesandla, ngogesi noma nge-zipper, futhi ingalungiswa kunoma iyiphi i-engeli engaphakathi kwebanga elingu-90°.

3. Ngenxa ye-single shaft kanye ne-single valve plate, amandla okuthwala anqunyelwe, futhi impilo yesevisi ye-valve imfushane ngaphansi kwezimo zomehluko omkhulu wokucindezela kanye nesivinini esikhulu sokugeleza.
