Ukubaluleka kokulawula ukuhamba okuthembekileyo nokusebenzayo kwizicelo zoshishino akunakugxininiswa kakhulu. Phakathi kweentlobo ngeentlobo zeevalvu ezisetyenziswa kwiinkqubo zemibhobho, iivalvu zebhola zibalasele ngokuqina kwazo, ukuguquguquka kwazo kunye nokulula kokusebenza. Njengoko ishishini liqhubeka liphuhla, indima yabavelisi beevalvu zebhola iya ibaluleke ngakumbi. Le blogi iza kuhlola ukubaluleka kwabavelisi beevalvu zebhola, iintlobo zeevalvu zebhola abazivelisayo, kunye nezinto ekufuneka ziqwalaselwe xa ukhetha umenzi weemfuno zakho ezithile.
Yintoni ivalvu yebhola?
Ivalvu yebhola yivalvu ejika ngekota esebenzisa ibhola engenanto, eneembobo, nejikelezayo ukulawula ukuhamba kolwelo. Xa umngxuma webhola uhambelana nolwelo, ivalvu iyavuleka, ivumela ulwelo ukuba ludlule. Xa ibhola ijika ngama-90 degrees, ukuhamba kwamanzi kuyavalwa. Olu yilo lulula kodwa olusebenzayo lwenza iivalvu zebhola zilungele ukusetyenziswa ukusuka kwiinkqubo zamanzi ukuya kwimibhobho yeoyile negesi.
Ukubaluleka Kwabavelisi Beevalvu Zebhola
Abavelisi beevalvu zebhola badlala indima ebalulekileyo ekuqinisekiseni ukuba amashishini ahlukeneyo afumana iivalvu ezikumgangatho ophezulu ezihlangabezana neemfuno zawo ezithile. Nazi ezinye zezizathu ezibalulekileyo zokuba aba bavelisi babaluleke:

Uqinisekiso lomgangatho lubalulekile kumashishini afana neoyile negesi, apho ukungasebenzi kakuhle kweevalvu kunokuba nemiphumo emibi kakhulu.
2. Ukwenza ngokwezifiso: Amashishini ahlukeneyo aneemfuno ezizodwa, kwaye xa kufikwa kwiivalvu, indlela yokulinganisa ubungakanani obunye ayizukusebenza. Abavelisi beevalvu zebhola abanobuchule banokubonelela ngezisombululo ezenzelwe wena kwiisicelo ezithile. Oku kuquka utshintsho kubukhulu, izixhobo kunye noyilo ukuhlangabezana neemfuno zeendawo ezahlukeneyo.
3. Ubuchule: Imeko yemizi-mveliso itshintsha rhoqo, kwaye abavelisi kufuneka bahambisane nobuchwepheshe obutsha kunye nezixhobo. Abavelisi abaphambili beevalvu zebhola batyala imali kuphando nophuhliso ukuze benze iimveliso ezintsha eziphucula ukusebenza, zinciphise ukugcinwa kunye nokwandisa ukusebenza kakuhle.
4. Inkxaso yoBugcisa: Abavelisi abathembekileyo banikezela ngenkxaso yobugcisa ukunceda abathengi bakhethe ivalvu efanelekileyo kwisicelo sabo. Oku kuquka ukufakela, ukugcinwa kunye nesikhokelo sokusombulula iingxaki ukuqinisekisa ukuba abathengi banokusebenzisa ubomi kunye nokusebenza kakuhle kwevalvu.
Iintlobo zeevalvu zebhola
Abavelisi beevalvu zebhola bavelisa iintlobo ezahlukeneyo zeevalvu zebhola ukuze zilungele ukusetyenziswa ezahlukeneyo. Nazi ezinye zeentlobo eziqhelekileyo:
1. Ivalvu yeBhola eDadayo: Kwivalvu yebhola edadayo, ibhola ayiqiniswanga endaweni yayo kodwa "iyadada" phakathi kwezihlalo. Olu yilo lwenza itywina eliqinileyo xa ivalvu ivaliwe, nto leyo eyenza ifaneleke ukusetyenziswa koxinzelelo oluphantsi ukuya koluphakathi.
2. Ivalvu yeTrunnion Ball: Iivalvu zeTrunnion ball zinebhola ezinzileyo exhaswa zii-trunnion (iiphini) phezulu nasezantsi. Olu yilo lufanelekile kwiindlela zokusetyenziswa koxinzelelo oluphezulu kuba lunciphisa i-torque efunekayo ukuze ivalvu isebenze kwaye inika isitywino esizinzileyo.
3. Ivalvu yeBhola ye-V-Port: Ezi valve zinebhola enomfanekiso we-V ukulawula ukuhamba kwamanzi ngokuchanekileyo. Zihlala zisetyenziswa kwiindawo apho kufuneka khona ukugoba, njengokucubungula iikhemikhali.
4. Ivalvu yebhola enezikhusi ezininzi: Ivalvu yebhola enezikhusi ezininzi ingakhokela ukuhamba kweendlela ezahlukeneyo, nto leyo eyenza ifaneleke kwiinkqubo zemibhobho ezintsonkothileyo. Zihlala zisetyenziswa kwiindawo apho indawo incinci kwaye kufuneka iindlela ezininzi zokuhamba kweendlela.
Izinto ekufuneka ziqwalaselwe xa ukhetha umenzi weevalvu zebhola
Ukukhetha umenzi weevalvu zebhola ofanelekileyo kubalulekile ukuqinisekisa impumelelo yeprojekthi yakho. Nazi ezinye izinto ekufuneka uziqwalasele:
1. Amava nodumo: Khangela abavelisi abanembali eqinisekisiweyo kushishino. Iinkampani ezinamava eminyaka emininzi zinamathuba amaninzi okuvelisa iimveliso ezisemgangathweni ophezulu kwaye zinike inkxaso ethembekileyo.
2. Iziqinisekiso kunye neMigangatho: Qinisekisa ukuba abavelisi bayahlangabezana nemigangatho yoshishino kwaye baneziqinisekiso ezifanelekileyo. Oku kubaluleke kakhulu kumashishini afana neoyile negesi apho ukhuseleko kunye nokuthembeka kubalulekile.
3. Ukukhetha Izinto: Usetyenziso olwahlukeneyo lufuna izinto ezahlukeneyo. Umenzi olungileyo kufuneka anikezele ngezinto ezahlukeneyo, kuquka intsimbi engatyiwayo, ubhedu kunye neplastiki, ukuze zilungele iindawo ezahlukeneyo kunye neentlobo ezahlukeneyo zolwelo.
4. Inkonzo yabathengi: Vavanya inqanaba lenkonzo yabathengi enikezelwa ngumvelisi. Iqela lenkxaso eliphendulayo nelinolwazi linokuyiphucula kakhulu amava akho, ingakumbi xa ufuna uncedo ngemibuzo yobugcisa okanye ukhetho lwemveliso.
5. Amaxabiso kunye neXesha lokuHanjiswa: Nangona ixabiso lingafanele libe lolona phawu lubalulekileyo kwisigqibo sakho, kubalulekile ukufumana umenzi onokubonelela ngamaxabiso akhuphisanayo ngaphandle kokubeka emngciphekweni umgangatho. Ukongeza, cinga ngamaxesha okuvelisa kunye namaxesha okuhambisa ukuqinisekisa ukuba iprojekthi yakho ihlala ikwixesha elibekiweyo.
ukuququmbela
Ngamafutshane, indima yabavelisi beevalvu zebhola ibalulekile ekuqinisekiseni ukuba ishishini lifumana izisombululo zokulawula ukuhamba kwamanzi ezinokuthenjwa nezisebenzayo. Ngokuqonda iintlobo ezahlukeneyo zeevalvu zebhola kunye nezinto ekufuneka ziqwalaselwe xa ukhetha umenzi, amashishini anokwenza izigqibo ezinolwazi eziya kuphucula imisebenzi yawo. Njengoko ishishini liqhubeka nokukhula, ukusebenza nomenzi weevalvu zebhola odumileyo kuya kuba ngundoqo kwimpumelelo kwindawo ekhuphisana ngakumbi. Nokuba ukwishishini leoyile negesi, ekucutshungulweni kweekhemikhali, okanye nakweyiphi na enye imboni exhomekeke kulawulo lolwelo, ukutyala imali kwivalvu yebhola esemgangathweni ophezulu lutyalo-mali kwixesha elizayo lomsebenzi wakho.
