Ziziphi iingxaki eziqhelekileyo kunye nezisombululo zeevalvu zeebhabhathane ngexesha lokusetyenziswa?
Ivalvu yebhabhathane ngenxa yobukhulu bayo obuncinci kunye nesakhiwo sayo esilula, iye yaba yenye yeevalvu ezisetyenziswa kakhulu kushishino, ngakumbi nangakumbi zisetyenziswa kumandla ombane wamanzi, ukunkcenkceshela, unikezelo lwamanzi kunye nokuhambisa amanzi, ubunjineli bomasipala kunye nezinye iinkqubo zemibhobho, ezisetyenziselwa ukunqumla okanye ukulungelelanisa ukuhamba kokuhamba kweendaba ezijikelezayo ukuze zisetyenziswe. Emva koko ivalvu yebhabhathane ekusebenziseni iingxaki ezifuna ingqalelo kunye nezisombululo zento, namhlanje siya kuba siqonde ngokucacileyo.
Ukufakwa kwevalvu yebhabhathane kubalulekile ekufuneka kuqwalaselwe:
1. Ngaphambi kokufakela, nceda uqinisekise ukuba ukusebenza kwemveliso kunye nokuhamba kwemidiya kuhambelana nokuhamba kweemeko zokusebenza, kwaye umngxuma wevalvu uya kucocwa ucocekile, ungavumeli ukungcola kwiringi yokutywina kunye neplate yebhabhathane enamathele kwizinto zangaphandle, ezingacocwanga ngaphambili azivumelekanga ukuvala iplate yebhabhathane, ukuze ingonakalisi iringi yokutywina.
2. Kucetyiswa ukuba ufake i-flange exhasa i-disc plate ukuze kusetyenziswe i-flange butterfly valve ekhethekileyo.
3. Ifakwe embindini wombhobho okanye kwindawo yeziphelo ezibini zombhobho, indawo engcono kakhulu yokufakelwa ngokuthe nkqo, ayinakufakelwa ijongise ezantsi.
4. Ukusetyenziswa kwesidingo sokulawula ukuhamba, kukho ii-actuators zesandla, zombane, zomoya zokulawula.
5. Vula kwaye uvale rhoqo ivalvu yebhabhathane, malunga neenyanga ezimbini, kufuneka uvule isigqubuthelo sebhokisi yegiya ye-worm, ujonge ukuba ibhotolo iqhelekile na, kwaye kufuneka ugcine ubungakanani obufanelekileyo bebhotolo.
6.Jonga ukuba iindawo zokudibanisa zicinezelwe na, oko kukuthi, ukuqinisekisa ukutywinwa kwepakeji, kodwa kwanokuqinisekisa ukuba ukujikeleza kwesiqu sevalvu kuyaguquguquka.
7. Iimveliso zevalvu yebhabhathane yentsimbi azifanelekanga ukufakwa ekupheleni kombhobho, njengoko kufuneka zifakwe ekupheleni kombhobho, kufuneka uthathe iflange yokuphuma efakelweyo, ukuthintela ukuqokelelwa koxinzelelo kwiringi yokutywina, phezu kwendawo.
8. Ukufakwa kwesiqu sevalvu kunye nokusetyenziswa kwempendulo ukujonga rhoqo ukusebenza kwevalvu, kufunyenwe iimpazamo ngexesha elifanelekileyo.
Izizathu ezinokubakho zokungaphumeleli: ukuvuza komphezulu wokuvala
1. Ipleyiti yeValve, ukuvalwa kwenkunkuma yefolda yomphezulu
2. Ipleyiti yevalvu, indawo yokuvala umphezulu wokutywina ihambelana nengalunganga
3. Uqwalaselo lwecala lokuphuma olufakelweyo lweebholiti zeflange ezingalinganiyo okanye iibholiti ezikhululekileyo
4. Isikhokelo sovavanyo loxinzelelo asihambelani neemfuno zesikhokelo sokuhamba komoya esiphakathi.
Iindlela zokususa
1. Susa ukungcola, coca umngxuma wangaphakathi wevalvu
2. Lungisa izixhobo zokulungisa ii-worm okanye izikrufu zombane, ezisebenzisa i-pneumatic actuator ukuze ufikelele kwindawo echanekileyo yokuvalwa kwevalvu
3. Ukujonga i-flange plane efakelweyo kunye nokubopha ucinezelo lwebholiti, kufuneka kucinezelwe ngokulinganayo
4.Ngokutsho kwesikhokelo sokutywina utolo loxinzelelo
Iivalvu ezimbini zibangela ukusilela kokuvuza
1.Zombini amacala okusilela kwe-gasket yokutywina
2. Ukuqina kweflange yepayipi akufani okanye akucinezelwanga
3. Indandatho yokutywina okanye indandatho yokutywina kwi-gasket engasebenzi kakuhle
Indlela yokususa
1. Buyisela i-gasket yokutywina
2. Iibholiti zeflange zoxinzelelo (amandla afanayo)
3.susa iringi yoxinzelelo lwevalvu, tshintsha iringi yokutywina kunye nokungasebenzi kakuhle kwegasket.
Ivalvu yebhabhathane inokwahlulwahlulwa ibe yivalvu yebhabhathane esembindini kunye nevalvu yebhabhathane engaqhelekanga ngokwemo yesakhiwo. Ngokwemo yesiciko inokwahlulwahlulwa ibe yimo yesiciko esithambileyo kunye nohlobo lwesiciko esiqinileyo. Uhlobo lwesiciko esithambileyo ngokubanzi lusebenzisa isihlalo sevalvu yerabha okanye isiciko seringi yerabha, uhlobo lwesiciko esiqinileyo ludla ngokusebenzisa isisiciko seringi yesinyithi. Ngokwemo yoqhagamshelo, inokwahlulwa ibe luqhagamshelo lweflange kunye noqhagamshelo lwewafer; ngokwemo yothumelo, inokwahlulwa ibe yi-manual, electric, pneumatic kunye ne-hydraulic. Singakhetha ii-actuators ezahlukeneyo ngokwemeko yokusebenza.
