Ziziphi iingxaki eziqhelekileyo kunye nezisombululo zeevalvu zebhabhathane ngexesha lokusetyenziswa?
Ivalve yebhabhathane ngenxa yobukhulu bayo obuncinci kunye nolwakhiwo olulula, iye yaba yenye yeevalvu ezisetyenziswa kakhulu kushishino, ngakumbi nangakumbi zisetyenziswa kumandla ombane wamanzi, ukunkcenkceshela, unikezelo lwamanzi okwakha kunye ne-drainage, ubunjineli bakamasipala kunye nezinye iinkqubo zemibhobho, ezisetyenziselwa ukunqumla okanye ukulamla ukuhamba kwemidiya ejikelezayo ukuze kusetyenziswe. Emva koko i-valve butterfly ekusetyenzisweni kweengxaki ezifuna ingqalelo kunye nezisombululo zeziphi, namhlanje siya kuba ngqo ukuqonda.
Ufakelo lwevalvu yebhabhathane imiba efuna ukuqwalaselwa:
1.Ngaphambi kofakelo, nceda uqinisekise ukusebenza kwemveliso kunye ne-media flow arrow ihambelana nokuhamba kweemeko zokusebenza, kwaye iya kuba yi-valve cavity scrubbed ecocekileyo, ungavumeli ukungcola kwindandatho yokutywina kunye nepleyiti yebhabhathane eqhotyoshelwe kwizinto zangaphandle, engacocwanga ngaphambi kokuba akukho ndlela ivunyelwe ukuvala i-butterfly plate, ukuze ungonakalisi umsesane wokutywina.
Ufakelo ipleyiti 2.Disc exhasa flange kucetyiswa ukuba usebenzise flange butterfly valve ekhethekileyo.
3.Ukufakwa phakathi kombhobho okanye indawo yeziphelo ezimbini zombhobho, indawo efanelekileyo yokufakela ngokuthe nkqo, ayikwazi ukufakwa phezulu.
4. Ukusetyenziswa kwemfuno yokulawula ukuhamba, kukho i-manual, umbane, i-pneumatic actuators yokulawula.
5. Vula kwaye uvale rhoqo ivelufa butterfly, malunga neenyanga ezimbini, kufuneka uvule isigqubuthelo ibhokisi gear worm, khangela ukuba ibhotolo eqhelekileyo, kufuneka ugcine isixa esifanelekileyo ibhotolo.
6.Khangela ukuba ngaba iindawo zokudibanisa zicinezelwe, oko kukuthi, ukuqinisekisa ukutywinwa kokupakisha, kodwa nokuqinisekisa ukuba ukujikeleza kwe-valve stem kuguquguqukayo.
7. Iimveliso zevalve yebhabhathane yentsimbi ayifanelekanga ukufakela ekupheleni kombhobho, njengoko kufuneka ifakwe ekupheleni kombhobho, kufuneka uthathe i-flange efakwe kwi-outlet, ukuthintela ukuqokelelwa kweringi yokutywina yoxinzelelo, ngaphezu kwendawo.
I-8.Ukufakwa kwe-valve stem kunye nokusetyenziswa kwempendulo ukujonga rhoqo ukusebenza kwe-valve, kufunyenwe iimpazamo ngexesha elifanelekileyo.
Izizathu ezinokwenzeka zokungaphumeleli: ukutywina ukuvuza komphezulu
I-1.Ipleyiti yeValve, i-debris yefolda yokutywina
I-2.Ipleyiti yeValve, indawo yokuvala umphezulu wokutywina ihambelana nokungalunganga
3. Uqwalaselo lwecala lokuphuma lufakela iibholithi zeflange ezingalinganiyo okanye iibholithi ezikhululekileyo
4.Ulwalathiso lovavanyo loxinzelelo alukho ngokweemfuno zendlela yokuhamba okuphakathi.
Iindlela zokuphelisa
1.Ukuphelisa ukungcola, hlambulula i-cavity yangaphakathi yevalve
2. Lungisa i-worm gear okanye umbane, i-pneumatic actuator yokulungisa izikrufu ukufezekisa indawo echanekileyo yokuvalwa kwevalve.
3.Ukukhangela indiza yeflange efakwe kunye ne-bolt compression fastening, kufuneka ixininiswe ngokufanayo
4.Ngokuhambelana notolo lokutywina icala loxinzelelo
I-Valve ezimbini iziphelo zokungaphumeleli kokuvuza
1.Macala omabini okusilela kwe-gasket yokutywina
I-2.I-pipe flange tightness ayifani okanye ayixinzelelwanga
3.Ukutywina umsesane okanye umsesane wokutywina ekungaphumeleli kwe-gasket
Indlela yokuphelisa
1.Buyisela i-gasket yokutywina
2.Iibholithi zeflange zoxinzelelo (amandla afanayo)
3. susa umsesane woxinzelelo lwevalve, buyisela umsesane wokutywina kunye nokusilela kwe-gasket.
Ivalve yebhabhathane inokohlulwa ibe yivalve yebhabhathane yomgca osembindini kunye nevalve yebhabhathane eccentric ngokwendlela yolwakhiwo. Ngokohlobo lokutywina lunokwahlulwa lube luhlobo lwetywina oluthambileyo kunye nodidi lwetywina elilukhuni. Uhlobo lokutywina oluthambileyo luqhele ukusebenzisa isitulo sevalve yerabha okanye ukutywinwa komsesane werabha, uhlobo lokutywina oluqinileyo ludla ngokusebenzisa ukutywinwa komsesane wentsimbi. Ngokohlobo loqhagamshelwano, lunokwahlulwa lube ludibaniso lwe-flange kunye noqhagamshelo lwe-wafer; ngokwendlela yothumelo, inokwahlulwa ibe yimanual, yombane, ipneumatic kunye nehydraulic. Sinokukhetha ii-activators ezahlukeneyo ngokweemeko zokusebenza.
