Ukubaluleka kokuthembeka, ukulawula ukuhamba ngokufanelekileyo kwizicelo zamashishini akukwazi ukugqithiswa. Phakathi kweentlobo ezahlukeneyo zeevalve ezisetyenziswa kwiinkqubo zemibhobho, iivalve zebhola zivelele ngenxa yokuqina kwazo, ubuninzi kunye nokulula ukusebenza. Njengoko ishishini liqhubeka nokuphuhlisa, indima yabavelisi bevalve yebhola iba yinto ebaluleke kakhulu. Le bhlog iya kuphonononga ukubaluleka kwabenzi bevalve yebhola, iintlobo zeevalvu zebhola abazivelisayo, kunye nezinto ekufuneka uziqwalasele xa ukhetha umenzi kwiimfuno zakho ezithile.
Yintoni ivalve yebhola?
Ivalve yebhola yivalve yokujika kwekota esebenzisa ibhola enomngxuma, enemingxuma, kunye nepivoting ukulawula ukuhamba kolwelo. Xa umngxuma webhola uhambelana nolwelo, ivelufa iyavuleka, ivumele ulwelo ukuba ludlule. Xa ibhola ijika i-90 degrees, ukuhamba kwamanzi kuvaliwe. Olu luyilo olulula kodwa olusebenzayo lwenza ukuba iivalvu zebhola zilungele ukusetyenziswa ukusuka kwiinkqubo zamanzi ukuya kwimibhobho yeoli negesi.
Ukubaluleka kwaBavelisi beValve yeBhola
Abavelisi bevalvu yebhola badlala indima ebalulekileyo ekuqinisekiseni ukuba amashishini ahlukeneyo afumana iivalvu ezikumgangatho ophezulu ezihlangabezana neemfuno zabo ezithile. Nazi ezinye zezizathu eziphambili zokuba kutheni aba bavelisi bebalulekile:
1. Ukuqinisekiswa koMgangatho: Abavelisi bevalve yebhola abahloniphekileyo bathobela imigangatho engqongqo yokulawula umgangatho. Oku kuqinisekisa ukuba iivalve eziveliswayo zinokwethenjelwa, zihlala ziqinile kwaye zikwazi ukumelana noxinzelelo kunye nobushushu boluhlu olubanzi lwezicelo. Ukuqinisekiswa komgangatho kubaluleke kakhulu kumashishini afana neoli kunye negesi, apho ukungaphumeleli kwevalvu kunokuba nemiphumo eyintlekele.
2. Ukwenza ngokwezifiso: Amashishini ahlukeneyo aneemfuno ezizodwa, kwaye xa kuziwa kwiivalve, indlela yokulinganisa enye ayiyi kusebenza. Abavelisi bevalve yebhola abanezakhono banokubonelela ngezisombululo ezilungiselelwe izicelo ezithile. Oku kubandakanya utshintsho kubukhulu, izixhobo kunye noyilo ukuhlangabezana neemfuno zeendawo ezahlukeneyo.
3. Utshintsho: Ubume boshishino buhlala buguquka, kwaye abavelisi kufuneka bahambisane nobuchwepheshe obutsha kunye nemathiriyeli. Abavelisi bevalve yebhola ekhokelayo batyala imali kuphando kunye nophuhliso ukwenza iimveliso ezintsha eziphucula ukusebenza, ukunciphisa ukugcinwa kunye nokwandisa ukusebenza kakuhle.
4. Inkxaso yezobuGcisa: Abavelisi abathembekileyo banikezela ngenkxaso yobugcisa ukunceda abathengi bakhethe i-valve efanelekileyo kwisicelo sabo. Oku kubandakanya ukufakela, ukugcinwa kunye nesikhokelo sokulungisa iingxaki ukuqinisekisa ukuba abathengi banokwandisa ubomi bevalvu kunye nokusebenza.
Iintlobo zeevalvu zebhola
Abavelisi bevalve yebhola bavelisa iintlobo ezahlukeneyo zeevalvu zebhola ukuze zihambelane nezicelo ezahlukeneyo. Nazi ezinye iintlobo eziqhelekileyo:
1. Ivalve yebhola edadayo: Kwivalve yebhola edadayo, ibhola ayimiselwanga endaweni kodwa “iyadada” phakathi kwezihlalo. Olu yilo ludala itywina eliqinileyo xa ivalve ivaliwe, iyenza ifanelekele izicelo zoxinzelelo oluphantsi ukuya phakathi.
2. I-Trunnion Ball Valve: Iivalvu zebhola ze-Trunnion zinebhola esisigxina exhaswa ngama-trunnions (izikhonkwane) phezulu nasezantsi. Olu luyilo lufanelekile kwizicelo zoxinzelelo oluphezulu kuba lunciphisa i-torque efunekayo ukuze isebenze i-valve kwaye inikeze isitywina esizinzile.
3. IValve yeBhola ye-V-Port: Ezi zivalo zinebhola efana ne-V yokulawula ukuhamba okuchanekileyo. Zihlala zisetyenziswa kwizicelo apho i-throttling ifuneka, njengokusetyenzwa kweekhemikhali.
4. Ivalve yebhola ye-Multi-port: Ivalve yebhola ye-Multi-port ingakhokela ukuhamba ngeendlela ezininzi, okwenza ukuba ifaneleke kwiinkqubo zemibhobho enzima. Ngokuqhelekileyo zisetyenziswa kwizicelo apho indawo incinci kwaye iindlela zokuhamba ezininzi ziyafuneka.
Izinto ekufuneka ziqwalaselwe xa ukhetha umenzi wevalvu yebhola
Ukukhetha umenzi wevalvu yebhola echanekileyo kubalulekile ekuqinisekiseni impumelelo yeprojekthi yakho. Nazi ezinye izinto ekufuneka ziqwalaselwe:
1. Amava kunye nodumo: Khangela abavelisi abanerekhodi eqinisekisiweyo kwishishini. Iinkampani ezineminyaka yamava ziyakwazi ukuvelisa iimveliso ezikumgangatho ophezulu kwaye zinike inkxaso ethembekileyo.
