Ivalvu yebhola njengohlobo oluqhelekileyo lwevalvu, ineendlela ezahlukeneyo zokusetyenziswa kunye neendlela ezahlukeneyo zokusetyenziswa. Oku kulandelayo yinjongo ephambili yokwazisa ngevalvu yebhola:
Okokuqala, nqumla okanye uqhagamshele i-pipeline medium
Umsebenzi osisiseko wevalvu yebhola kukunqumla okanye ukudibanisa i-medium ekwipayipi. Ngokujikelezisa ibhola, ivalvu ingavulwa okanye ivalwe ngokukhawuleza ukulawula ukuhamba kwe-medium. Lo msebenzi wenza ivalvu yebhola isetyenziswe kakhulu ekucoceni ipetroliyam, kwimibhobho emide, kushishino lweekhemikhali, ekwenzeni amaphepha, kumayeza, ekugcinweni kwamanzi, kumbane, kumasipala, kwintsimbi nakwamanye amashishini.
Okwesibini, lungisa ukuhamba kolwelo
Ezinye iivalvu zebhola (ezifana neevalvu zebhola ezimile okwe-V) zinomsebenzi wokulawula ukuhamba kolwelo. Ngokutshintsha i-Angle yokujikeleza kwebhola, izinga lokuhamba kolwelo lingalungiswa ukuze kufezekiswe ulawulo oluchanekileyo lokuhamba kolwelo. Lo msebenzi uvumela iivalvu zebhola ukuba zisetyenziswe kwiimeko apho kufuneka ulawulo oluchanekileyo lokuhamba kolwelo, njengolawulo lokutya kwii-reactors zeekhemikhali.
Okwesithathu, tshintsha indlela yokuhamba kombane
Iivalvu zebhola zingasetyenziselwa ukutshintsha indlela yokuhamba kwesixhobo. Iivalvu zebhola ezidlula ngeendlela ezininzi (ezifana nohlobo lwe-T, uhlobo lwe-L, njl.njl.) zinokulawula ngokuguquguquka indlela edibana ngayo isixhobo, ukuphambuka kunye nendlela yokuhamba kwesixhobo kwipayipi ukuze kuhlangatyezwane neemfuno zeenkqubo zepayipi ezintsonkothileyo.
Okwesine, thintela ukubuya kwe-medium
Iivalvu zebhola nazo zingadlala indima ebalulekileyo kwiimeko apho i-medium kufuneka ithintelwe ukuba ingabuyeli emva. Ngokufaka iintlobo ezikhethekileyo zeevalvu zebhola ezifana neevalvu zebhola zokujonga, i-media inokuthintelwa ukuba ingabuyeli emva kwipayipi ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo.
Okwesihlanu, ezinye iinjongo ezikhethekileyo
Ukongeza kwiindlela ezisisiseko ezingentla, iivalvu zebhola zinokwenziwa ngokwezifiso kwaye ziyilwe ngokweemfuno ezithile ukuhlangabezana neemfuno zeziganeko ezikhethekileyo. Umzekelo, xa kufuneka ubushushu obuphezulu, uxinzelelo oluphezulu, ukugqwala kunye nezinye iimeko zokusebenza ezigqithisileyo, iivalvu zebhola kunye nezitywino ezikhethekileyo zingasetyenziselwa ukuqinisekisa ukusebenza okuqhelekileyo kwevalvu kunye nokuzinza kwexesha elide.
Umzekelo wentsimi yesicelo
Ukucocwa kwepetroliyam: Kwinkqubo yokucocwa kwepetroliyam, iivalvu zebhola zisetyenziselwa ukulawula ukuhamba kunye nokunqunyulwa kweemveliso ezahlukeneyo zeoli ukuqinisekisa inkqubela phambili ethe tye yenkqubo yemveliso.
Umbhobho womgama omde: Kwinkqubo yombhobho womgama omde, ivalvu yebhola isetyenziselwa ukusika okanye ukudibanisa isixhobo sokudlulisa umgama omde (njengegesi yendalo, ioyile eluhlaza, njl.njl.) ukuqinisekisa ukusebenza ngokukhuselekileyo nangokuzinzileyo kombhobho.
Ishishini leekhemikhali: Kwishishini leekhemikhali, iivalvu zebhola zisetyenziselwa ukulawula ukuhamba kweendaba ezahlukeneyo ezibolayo kunye nolawulo lokutya ngexesha lenkqubo yokusabela.
Amayeza: Kwishishini lamayeza, iivalvu zebhola zisetyenziselwa ukulawula ukuhamba kunye nokunqunyulwa kweendlela ezahlukeneyo zolwelo kwinkqubo yokuveliswa kwamayeza.
Ngamafutshane, iivalvu zebhola zisetyenziswa kakhulu kumashishini amaninzi ngenxa yesakhiwo sazo esahlukileyo kunye neenzuzo zokusebenza, kwaye ziye zaba yenye yezona zinto zibalulekileyo nezibalulekileyo kwiinkqubo zemibhobho.
