Ukubaluleka kokulawulwa okuthembekile, okusebenzayo kokugeleza kwezinhlelo zokusebenza zezimboni akukwazi ukweqiwa. Phakathi kwezinhlobo ezahlukene zama-valve asetshenziswa ezinhlelweni zamapayipi, ama-valve ebhola agqama ngenxa yokuqina kwawo, ukuguquguquka nokusebenza kalula. Njengoba imboni iqhubeka nokuthuthuka, indima yabakhiqizi be-valve yebhola iba ngokubaluleke kakhulu. Le bhulogi izohlola ukubaluleka kwabakhiqizi be-valve yebhola, izinhlobo zama-valve ebhola abawakhiqizayo, nezici okufanele uzicabangele lapho ukhetha umenzi ngezidingo zakho ezithile.
Iyini i-valve yebhola?
I-valve yebhola iyi-valve yokujika kwekota esebenzisa ibhola elingenalutho, elinezimbobo, kanye ne-pivoting ukulawula ukugeleza koketshezi. Lapho imbobo yebhola ihambisana noketshezi, i-valve iyavuleka, ivumele uketshezi ukuba ludlule. Lapho ibhola liphenduka ama-degree angu-90, ukugeleza kwamanzi kuvinjelwe. Lo mklamo olula kodwa osebenzayo wenza ama-valve ebhola alungele ukusetshenziswa kusukela kumasistimu amanzi kuya kumapayipi kawoyela negesi.
Ukubaluleka Kwabakhiqizi Bevalvu Yebhola
Abakhiqizi bamavalvu ebhola badlala indima ebalulekile ekuqinisekiseni ukuthi izimboni ezahlukene zithola amavalvu eqophelo eliphezulu ahlangabezana nezidingo zawo ezithile. Nazi ezinye izizathu ezibalulekile zokuthi kungani laba bakhiqizi bebalulekile:
1. Ukuqinisekiswa Kwekhwalithi: Abakhiqizi be-valve bebhola abahlonishwayo banamathela ezindinganisweni eziqinile zokulawula ikhwalithi. Lokhu kuqinisekisa ukuthi ama-valve akhiqizwayo anokwethenjelwa, aqinile futhi akwazi ukumelana nezingcindezi namazinga okushisa ezinhlobonhlobo zezicelo. Ukuqinisekisa ikhwalithi kubalulekile ezimbonini ezifana nowoyela negesi, lapho ukwehluleka kwamavalvu kungaba nemiphumela eyinhlekelele.
2. Ukwenza ngokwezifiso: Izimboni ezahlukene zinezidingo ezihlukile, futhi uma kuziwa kuma-valve, indlela yokulinganisa usayizi owodwa ngeke isebenze. Abakhiqizi be-valve bebhola abanekhono banganikeza izixazululo ezenziwe ngokwezifiso zezicelo ezithile. Lokhu kuhlanganisa izinguquko ngobukhulu, izinto zokwakha kanye nomklamo ukuhlangabezana nezidingo zezindawo ezahlukene.
3. Ukuqamba okusha: Isimo sezimboni sihlala sishintsha, futhi abakhiqizi kufanele bahambisane nobuchwepheshe obusha nezinto zokwakha. Abakhiqizi abahamba phambili be-valve yebhola batshala imali ocwaningweni nasekuthuthukisweni ukuze bakhe imikhiqizo emisha ethuthukisa ukusebenza, enciphisa ukugcinwa nokwandisa ukusebenza kahle.
4. Ukusekelwa Kwezobuchwepheshe: Abakhiqizi abanokwethenjelwa banikeza ukwesekwa kwezobuchwepheshe ukusiza amakhasimende akhethe i-valve efanele yesicelo sabo. Lokhu kuhlanganisa ukufakwa, ukugcinwa kanye neziqondiso zokuxazulula izinkinga zokuqinisekisa ukuthi amakhasimende angakwazi ukwandisa ukuphila kwama-valve nokusebenza.
Izinhlobo zama-valve ebhola
Abakhiqizi be-valve yebhola bakhiqiza izinhlobo ezahlukene zama-valve ebhola ukuze zivumelane nezinhlelo zokusebenza ezahlukene. Nazi ezinye izinhlobo ezivamile:
1. I-Valve yebhola entantayo: Ku-valve yebhola entantayo, ibhola aligxilile endaweni kodwa “liyantanta” phakathi kwezihlalo. Lo mklamo udala uphawu oluqinile lapho i-valve ivaliwe, okwenza ifaneleke ukucindezela okuphansi kuya kokuphakathi.
2. I-Trunnion Ball Valve: Amavalvu ebhola e-Trunnion anebhola elingashintshi elisekelwa ama-trunnions (amaphini) phezulu nangaphansi. Lo mklamo ulungele izinhlelo zokusebenza zokucindezela okuphezulu ngoba unciphisa i-torque edingekayo ukuze kusetshenziswe i-valve futhi inikeza uphawu oluzinzile.
3. I-V-Port Ball Valve: Lawa mavalvu anebhola elimise okwe-V lokulawula ukugeleza okunembile. Zivame ukusetshenziselwa izinhlelo zokusebenza lapho kudingeka khona ukugoqa, njengokucutshungulwa kwamakhemikhali.
4. Ivalvu yebhola enamachweba amaningi: Ivalvu yebhola enamachweba amaningi ingaqondisa ukugeleza ezindaweni eziningi, iyenze ifanele amasistimu amapayipi ayinkimbinkimbi. Ngokuvamile zisetshenziswa ezinhlelweni lapho isikhala sinomkhawulo futhi kudingeka izindlela zokugeleza eziningi.
Izinto okufanele uzicabangele lapho ukhetha umenzi we-valve yebhola
Ukukhetha umkhiqizi we-valve yebhola ofanele kubalulekile ukuze uqinisekise impumelelo yephrojekthi yakho. Nazi ezinye izici okufanele zicatshangelwe:
1. Isipiliyoni Nesithunzi: Bheka abakhiqizi abanerekhodi eliqinisekisiwe embonini. Izinkampani ezinokuhlangenwe nakho kweminyaka kungenzeka zikhiqize imikhiqizo yekhwalithi ephezulu futhi zinikeze ukwesekwa okuthembekile.
2. Izitifiketi Namazinga: Qinisekisa ukuthi abakhiqizi bahlangabezana nezindinganiso zomkhakha futhi baphethe izitifiketi ezifanele. Lokhu kubaluleke kakhulu ezimbonini ezifana nowoyela negesi lapho ukuphepha nokuthembeka kubaluleke kakhulu.
3. Ukukhethwa Kwezinto Ezibalulekile: Izinhlelo zokusebenza ezahlukene zidinga izinto ezahlukene. Umkhiqizi omuhle kufanele anikeze uhla lwezinto, okuhlanganisa insimbi engagqwali, ithusi nepulasitiki, ukuze ivumelane nezinhlobonhlobo zezindawo kanye nezinhlobo eziwuketshezi.
4. Isevisi Yekhasimende: Linganisa izinga lesevisi yamakhasimende elinikezwa umenzi. Ithimba losekelo eliphendulayo nelinolwazi lingathuthukisa kakhulu umuzwa wakho, ikakhulukazi uma udinga usizo ngemibuzo yobuchwepheshe noma ukukhetha kwemikhiqizo.
5. Intengo Nesikhathi Sokulethwa: Nakuba izindleko kungafanele kube ukuphela kwesici esinqumweni sakho, kubalulekile ukuthola umkhiqizi onganikeza amanani ancintisanayo ngaphandle kokuyekethisa ikhwalithi. Ukwengeza, cabanga izikhathi zokuhola zokukhiqiza nezokulethwa ukuze uqinisekise ukuthi iphrojekthi yakho ihlala kushejuli.
Ekuphetheni
Kafushane, indima yabakhiqizi be-valve yebhola ibalulekile ekuqinisekiseni ukuthi imboni ithola izixazululo ezithembekile, ezisebenza kahle zokulawula ukugeleza. Ngokuqonda izinhlobo ezahlukene zama-valve ebhola kanye nezici okufanele zicatshangelwe lapho ukhetha umenzi, amabhizinisi angenza izinqumo ezinolwazi ezizothuthukisa ukusebenza kwawo. Njengoba imboni iqhubeka nokuthuthuka, ukusebenza nomkhiqizi wamavalvu ebhola ohlonishwayo kuzoba ukhiye empumelelweni endaweni eya ngokuya iqhudelana. Noma ngabe ukumboni kawoyela negesi, ukucutshungulwa kwamakhemikhali, nanoma iyiphi enye imboni ethembele ekulawuleni uketshezi, ukutshala imali kuvalvu yebhola yekhwalithi ephezulu kuwutshalomali esikhathini esizayo somsebenzi wakho.
