Ukubaluleka kolawulo oluthembekileyo, olululo lokulawula okuthe kratya kwizicelo zeshishini akunakuba ngaphezulu. Phakathi kweentlobo ezahlukeneyo zeevalves ezisetyenzisiweyo kwiinkqubo zokwenza imibhobho, i-valves yebhola zimele ukuqina, zokungasebenzi kakuhle kunye nokusebenza ngokulula. Njengoko ishishini liyaqhubeka nokuphuhlisa, indima yabavelisi beValva yeValve ibaluleka ngakumbi. Ibhlog iyakuphonononga ukubaluleka kwabavelisi beValve Valve, iintlobo zeeValve abazivelisayo, kunye nezinto ekufuneka ziqwalaselwe xa ukhetha umenzi weemfuno zakho ezithile.
Yintoni ivali yebhola?
Ivalve yebhola yi-valve yekota esebenzisa i-hollow, i-ofisinisiweyo, kunye nebhola epilisi yokulawula ukuhamba kwamanzi. Xa umngxunya webhola ehambelana nolwelo, ivalve ivula, ivumela amanzi ukuba adlule. Xa ibhola ijika ingama-90 degrees, ukuhamba kwamanzi kuvaliwe. Olu hlobo loyilo olusebenzayo olulula olo kwenza i-valves yebhola ilungele izicelo isusela kwiinkqubo zamanzi ukuya kwii-oyile kunye nemibhobho yegesi.
Ukubaluleka kwabavelisi beValve Palve
Abavelisi be-valve bebhola badlala indima ebalulekileyo ekuqinisekiseni ukuba amashishini ahlukeneyo afumana i-valde emilinganiselo ephezulu ahlangabezana neemfuno zabo ezithile. Nazi ezinye zezizathu ezibalulekileyo zokuba abavelisi babalulekile:
1. Uqinisekiso lwemilinganiselo Oku kuqinisekisa ukuba i-valves ivele ithembekile, iqinile kwaye iyakwazi ukumelana noxinzelelo lweengcinezelo kunye nolwahlulo olubanzi lwezicelo. Uqinisekiso lomgangatho lubalulekile kumashishini anje ngeoyile negesi, apho ukusilela kwe-valve kunokuba nemiphumo emibi.
2. Ukuzaliswa ngokwezifiso: Amashishini ahlukeneyo aneemfuno ezizodwa, kwaye xa kufikwa kwiivalve, i-vial-fire-fire-fire-fill-yonke indlela ayizukusebenza. Abavelisi beVoal Valve yeBhola yeBhola yeNjolo banokubonelela ngezisombululo ezenziwe ngokwezixhobo zezicelo ezithile. Oku kubandakanya utshintsho kubungakanani, izixhobo kunye noyilo lokuhlangabezana neemfuno ezahlukeneyo.
3. Ukuveliswa kweMveliso: Ubume bemizi-mveliso zihlala zitshintsha, kwaye abavelisi kufuneka baqhubeke neetekhnoloji ezintsha kunye nezixhobo. Abavelisi beValve Bakhokelayo batyala imali kuphando kunye nophuhliso ukwenza iimveliso ezinokuphucula ukusebenza, ukunciphisa ulondolozo kunye nokunyusa ukusebenza kakuhle.
4. Inkxaso yezobuchwephesha: Abavelisi abathembekileyo babonelela ngenkxaso yezobuchwephesha ukunceda abathengi bakhetha ivalve efanelekileyo ukuze basebenzise. Oku kubandakanya ufakelo, ulondolozo kunye nokuchonga isikhokelo sokuvuselela ingxaki ukuqinisekisa ukuba abathengi banokukhulisa i-valve kunye nendlela yokusebenza.
Iindidi zeevali zebhola
Abavelisi be-valve bebhola bavelisa iintlobo ezahlukeneyo zeeVenkile zeeBhola zeeValves ukuze zilungele izicelo ezahlukeneyo. Nazi ezinye iintlobo eziqhelekileyo:
1. Ivalve yokudada i-valve: Kwivalve yebhola edadayo, ibhola ayigcinwanga endaweni kodwa "dadas" phakathi kwezihlalo. Olu pholo lwenza itywina eliqinileyo xa ivalve ivaliwe, iyenza ilungele izicelo eziphantsi zoxinzelelo.
I-2. Ibhotile yebhola kaTrunnion: I-Trunnion Ball Valves ibhola emiselweyo exhaswa yi-trunnions (izikhonkwane) ngaphezulu nasezantsi. Oluyilo lulungele izicelo zoxinzelelo oluphezulu kuba kunciphisa i-torque kufuneka ukuba isebenze ivalve kwaye inike itywina elizinzileyo ngakumbi.
I-3. V-Port Illve: Ezi valves zibonisa ibhola ye-V-efakwe kwi-V. Zihlala zisetyenziswa kwizicelo apho kufuneka khona i-hertling, njengokuqhubekeka nemichiza.
I-4. I-Potli-Port Polve yeBhola yePort: I-Volve-Porti-Port Port Prolve inokukhokelela ekuhambeni kwezikhokelo ezininzi, iyenza ilungele iinkqubo ezintsonkothileyo zemibhobho. Ziqhelekile ezisetyenziswa kwizicelo apho indawo inqunyelwe kwaye iindlela ezininzi zokuhamba ziyafuneka.
Izinto ekufuneka ziqwalaselwe xa ukhetha umenzi we-valve
Ukukhetha umenzi wevala yebhola efanelekileyo kubalulekile ekuqinisekiseni impumelelo yeprojekthi yakho. Nazi ezinye izinto ekufuneka ziqwalaselwe:
I-1. Amava nodumo: Khangela abavelisi ngerekhodi eqinisekisiweyo kwishishini. Iinkampani ezineminyaka yamava kunokwenzeka ukuba zivelise iimveliso ezisemgangathweni eziphezulu kwaye zinike inkxaso ethembekileyo.
2. Ukuthathwa ngokuqondelweyo: Oku kubaluleke ngakumbi kumashishini anjengeoyile kunye negesi apho ukhuseleko kunye nokuthembeka kubalulekile.
3. Ukukhetha izinto eziphathekayo: Izicelo ezahlukeneyo zifuna izixhobo ezahlukeneyo. Umenzi olungileyo kufuneka anike uluhlu lwezixhobo, kubandakanya intsimbi engenasimo, ubhedu kunye neplastiki, ukuze ahambelane neemeko ezahlukeneyo kunye neendidi zolwelo.
4. Inkonzo yabaThengi: Vavanya inqanaba lenkonzo yabathengi ebonelelwe ngumenzi. Iqela eliphendulayo nelwazi elinolwazi linokuphucula kakhulu amava akho, ngakumbi xa ufuna uncedo ngemibuzo yezobugcisa okanye ukhetho lwemveliso.
5. Amaxabiso kunye neXesha lokuHanjiswa: Ngelixa iindleko akufuneki zibe kuphela kwesixhobo sakho kwisigqibo sakho, kubalulekile ukufumana umvelisi onokuthi asebenzise amaxabiso okhuphiswano ngaphandle kokulalanisa kumgangatho. Ukongeza, qwalasela imveliso kunye nokuhanjiswa kwamaxesha okukhokelela ukuqinisekisa ukuba iprojekthi yakho ihleli kwishedyuli.
ukuququmbela
Isishwankathelo, indima yomenzi weVenkile yeBholo ibaluleke kakhulu ekuqinisekiseni ukuba ishishini lifumana izisombululo ezinokuthenjwa, ezisebenzayo. Ngokuqonda iindidi ezahlukeneyo zeevali zebhola kunye nezinto ekufuneka ziqwalaselwe xa ukhetha umenzi, amashishini anokwenza izigqibo ezinolwazi eziya kuthi ziphucule imisebenzi yazo. Njengoko ishishini liyaqhubeka nokuvela, ukusebenza ngomenzi weValva odumileyo oya kuba sisitshixo sempumelelo kwindawo eyandayo. Nokuba ukwishishini leoyile negesi, ukuqhubekisa kwegesi, okanye nawuphi na omnye umzi mveliso oxhomekeke kulawulo lwe-fluid, utyalomali kwivali ekumgangatho ophezulu yebhola lutyalo mali kwixa elizayo lokusebenza kwakho.
