Xa kuziwa kwizicelo zamashishini ezibandakanya ulawulo lwamanzi, umgangatho wamacandelo evalve ubalulekile. Elinye lamalungu adlala indima ebalulekileyo ekusebenzeni kwevalvu yibhola yevalvu enomngxuma. Ezi bhola zenziwe ngendlela echanekileyo zisetyenziswa kumashishini ahlukeneyo, kuquka i-oyile negesi, ukulungiswa kweekhemikhali, kunye nokuveliswa kwamandla. Ke ngoko, ukukhetha umenzi webhola enomgongxo ochanekileyo kubalulekile ekuqinisekiseni ukuthembeka kunye nokusebenza kakuhle kweevalvu eziyisebenzisayo.
UQinisekiso loMgangatho kunye nobuNjineli obuchanekileyo
Abavelisi bebhola enomgongxo abahloniphekileyo bayayiqonda indima ebalulekileyo edlalwa ngala malungu kumsebenzi jikelele wevalvu. Ke ngoko, babeka phambili ukuqinisekiswa komgangatho kunye nobunjineli obuchanekileyo ngexesha lenkqubo yabo yokuvelisa. Oku kubandakanya ukusebenzisa izinto ezikumgangatho ophezulu ezifana nensimbi engenasici, i-carbon steel okanye ezinye i-alloys ukuqinisekisa ukuqina kunye nokumelana nokugqwala kwebhola elingenanto.
Ukongeza, iindlela zobunjineli ezichanekileyo ezinje ngomatshini we-CNC kunye nokusila zisetyenziselwa ukufezekisa imilinganiselo echanekileyo kunye nokugqiba umphezulu ofunekayo ekusebenzeni ngokufanelekileyo. Ukuthathela ingqalelo kwiinkcukacha kubalulekile ekuqinisekiseni ukuba iibhola zevalvu ezingenanto ziyahlangabezana nemigangatho engqongqo ebekwe yimigaqo yoshishino kunye neenkcukacha.
Ukwenza ngokwezifiso kunye nokuguquguquka
Kwiinkqubo ezininzi zemizi-mveliso, iibhola zevalve ezingaphandle kweshelufu zinokungasoloko zihlangabezana neemfuno ezithile zoyilo lwevalvu ethile okanye imeko yokusebenza. Kulapho ubuchule bomenzi ohloniphekileyo bungena khona. Bafanele banikeze ukulungelelaniswa kunye nokuguquguquka kwizakhono zemveliso ukulungiselela iinkcukacha ezizodwa kunye neemfuno zoyilo.
Nokuba libakala elithile lemathiriyeli, ukunyamezelwa kobukhulu okanye ukugquma komphezulu, umenzi othembekileyo kufuneka akwazi ukusebenza ngokusondeleyo nabathengi ukubonelela ngezisombululo ezilungelelanisiweyo ezihlangabezana neemfuno zabo kanye. Lo mgangatho wokwenza ngokwezifiso uqinisekisa ukuba ibhola ye-valve evulekileyo ilungiselelwe isicelo esithile, ekugqibeleni inceda ukunyusa ukusebenza kakuhle kunye nexesha elide le-valve efakwe.
Ulawulo lomgangatho kunye novavanyo
Ukusebenza kunye nokuthembeka kweebhola zevalve ezingenanto zihambelana ngokuthe ngqo kumanyathelo okulawula umgangatho ophunyezwe ngexesha lokwenziwa kwenkqubo yokuvelisa. Abavelisi abahlonelwayo baya kuba nemigaqo engqongqo yolawulo lomgangatho ukuqinisekisa ukuba ibhetshi nganye yeebhola zevalvu ezingenanto iyahlangabezana nemigangatho efunekayo.
Oku kubandakanya uhlolo olucokisekileyo, uvavanyo lwemathiriyeli kunye novavanyo lokugqiba umphezulu ukuchonga nakuphi na ukutenxa kwiimfuno ezichaziweyo. Ukongezelela, iimvavanyo ezisebenzayo ezifana noxinzelelo kunye novavanyo lokuhamba lunokwenziwa ukuze kuqinisekiswe ukusebenza kwebhola ye-valve engenanto phantsi kweemeko zehlabathi langempela. Ngokuthobela ulawulo olungqongqo lwemigangatho kunye neenkqubo zokuvavanya, abavelisi banokufaka ukuzithemba kubathengi babo ngokuthembeka kunye nokuhambelana kweemveliso zabo.
Hlangana nemigangatho yoshishino
Kumashishini alawulwa kakhulu apho iibhola zevalve ezingenanto zisetyenziswayo, ukuthotyelwa kwemigangatho yoshishino kunye neziqinisekiso akunakuxoxwa. Umenzi othembekileyo kufuneka azibophelele ekudibaneni kwaye agqithe le migangatho, nokuba yi-API, ASME, ASTM, okanye ezinye iinkcukacha ezifanelekileyo.
Ngokuthobela imigangatho yoshishino, abavelisi banokuqinisekisa ukuba iibhola zabo zevalve ezingenanto ziyilwe kwaye zenziwe ukuba zimelane neendawo zokusebenza ezibuhlungu abaza kudibana nazo. Oku akuqinisekisi kuphela umgangatho wemveliso kodwa kwenza kube lula ukuvunywa kunye nenkqubo yokuqinisekiswa kweevalvu ezineebhola ezidibeneyo ezingenanto.
Intsebenziswano yexesha elide kunye nenkxaso
Ukukhetha umenzi webhola enomgongxo ochanekileyo akukhona nje malunga nomgangatho wokuqala wemveliso, kodwa malunga nokuseka intsebenziswano yexesha elide. Umenzi othembekileyo kufuneka abonelele ngenkxaso eqhubekayo, ubuchule bobugcisa, kunye nenkonzo yabathengi ephendulayo ukujongana nayo nayiphi na imiba okanye iimfuno ezinokuvela kumjikelezo wobomi bevalve.
Oku kubandakanya ukubonelela ngesikhokelo ekukhetheni izinto eziphathekayo, ukulungelelaniswa koyilo kunye noncedo lokusombulula iingxaki ukuqinisekisa ukuba ibhola yevalve enomngxuma iyaqhubeka ukusebenza ngokugqibeleleyo. Ukongeza, ukuzibophelela kwabavelisi kuphuculo oluqhubekayo kunye nokuveliswa kwezinto ezintsha kunokukhokelela kuphuhliso lwezisombululo zebhola ezingenanto ezibonelela ukusebenza okuphezulu kunye nobomi benkonzo obude.
Isishwankathelo, ukubaluleka kokukhetha umenzi webhola yevalve enemingxuma elungileyo ayinakugqithiswa. Ukususela ekuqinisekiseni umgangatho kunye nobunjineli obuchanekileyo ukwenza ngokwezifiso, ukulawulwa komgangatho, ukuthotyelwa kwemigangatho yoshishino, kunye nenkxaso yexesha elide, abavelisi abahloniphekileyo badlala indima ebalulekileyo ekuqinisekiseni ukuthembeka kunye nokusebenza kakuhle kweevalve kwiinkqubo ezahlukeneyo zoshishino. Ngokubambisana nomenzi othembekileyo, amashishini anokuzithemba ekusebenzeni kwamacandelo abo e-valve, ekugqibeleni abe negalelo kwimpumelelo yonke yemisebenzi yabo.
