Umgaqo wokusebenza kunye neendawo zokwakha kunye nofakelo lwe-rubber ehleli i-butterfly valve

Iirabha ehleli ivelufa yebhabhathaneluhlobo lwevalve esebenzisa ipleyiti yebhabhathane ejikelezayo njengenxalenye yokuvula kunye nokuvala kwaye ijikelezisa ngesikhondo sevalve ukuvula, ukuvala kunye nokulungelelanisa umjelo wolwelo. Ipleyiti butterfly yeirabha ehleli ivelufa yebhabhathaneifakwe kwidamitha yecala lombhobho. Kwijelo lecylindrical yeirabha ehleli ivelufa yebhabhathaneumzimba, ipleyiti yebhabhathane emilise idiskhi ijikeleza i-axis, kwaye i-engile yokujikeleza iphakathi kwe-0 ° kunye ne-90 °. Xa ijikeleza kwi-90 °, i-valve ivuleke ngokupheleleyo.

Iindawo zokwakha kunye nokufakwa

1. Isikhundla sofakelo, ubude, kunye nesalathiso sokungenisa kunye nokuthumela ngaphandle kufuneka kuhlangabezane neemfuno zoyilo, kwaye umdibaniso kufuneka uqine kwaye uqine.

2. Kuzo zonke iintlobo zeevalvu ezifakwe kwi-thermal insulation pipeline, isiphatho asiyi kuba phantsi.

3. Ukuhlolwa okubonakalayo kufuneka kwenziwe ngaphambi kokuba i-valve ifakwe, kwaye i-nameplate yevalve kufuneka ihlangabezane neemfuno zomgangatho wangoku welizwe "I-General Valve Mark" GB12220. Kwi-valve esebenza ngoxinzelelo olukhulu kune-1.0MPa kwaye idlala indima ekunqumleni umbhobho oyintloko, amandla kunye novavanyo oluqinileyo kufuneka luqhutywe ngaphambi kokufakwa, kwaye kuvunyelwe ukusetyenziswa emva kokuphumelela uvavanyo. Ngexesha lovavanyo lwamandla, uxinzelelo lovavanyo luyi-1.5 amaxesha oxinzelelo oluncinci, kwaye ubude bexesha abukho ngaphantsi kwemizuzu emi-5. Izindlu zevalve kunye nokupakishwa kufuneka zifaneleke ngaphandle kokuvuza. Kuvavanyo lwe-tightness, uxinzelelo lovavanyo luyi-1.1 amaxesha oxinzelelo lwegama; Uxinzelelo lovavanyo kufuneka luhlangabezane neemfuno zomgangatho we-GB50243 ngexesha lovavanyo, kwaye i-valve disc yokutywinwa kwendawo yokutywina ifanelekile ukuba akukho kuvuza.

Amanqaku okukhetha imveliso

1. Iiparamitha zolawulo eziphambili zeirabha ehleli ivelufa yebhabhathanelubalulo kunye nemilinganiselo.

2. Inokuthi iqhutywe ngesandla, ngombane okanye nge-zipper, kwaye inokulungiswa kuyo nayiphi na i-angle ngaphakathi koluhlu lwe-90 °.

3. Ngenxa ye-shaft enye kunye neplate ye-valve enye, umthamo wokuthwala ukhawulelwe, kwaye ubomi benkonzo ye-valve bufutshane phantsi kweemeko zokuhluka koxinzelelo olukhulu kunye nesantya esikhulu sokuhamba.
