Ucabanga ukuthi i-valve yakho ivumela ukugeleza okuphezulu, kodwa isistimu yakho ayisebenzi kahle. Ivalvu oyikhethile kungenzeka iklinya ulayini, yehlise ngokuthula ingcindezi nokusebenza kahle ngaphandle kokwazi ukuthi kungani.

Akuwona wonke ama-valve ebhola e-PVC anembobo egcwele. Eziningi ziyizimbobo ezijwayelekile (ezibizwa nangokuthi ichweba elincishisiwe) ukonga izindleko nendawo. I-valve yembobo egcwele inembobo elingana nepayipi lokugeleza okungavinjelwe ngokuphelele.

Lona imininingwane ebalulekile ekwakhiweni kwesistimu, futhi kuyinto engixoxa ngayo kaningi nozakwethu, okuhlanganisa nethimba lika-Budi e-Indonesia. Ukukhetha phakathi kwembobo egcwele kanye nembobo evamile kuthinta ngokuqondile ukusebenza kwesistimu. Kumakhasimende akwaBudi angosonkontileka, ukuthola leli lungelo kusho umehluko phakathi kwesistimu esebenza kahle kakhulu naleyo engahlangabezani nokulindelwe. Ngokuqonda lo mehluko, bangakhetha i-valve ye-Pntek ephelele yawo wonke umsebenzi, baqinisekise ukwaneliseka kwamakhasimende nokwakha idumela labo lomsebenzi wekhwalithi.

Ingabe i-valve yebhola iyimbobo egcwele yembobo?

Udinga ukugeleza okuphezulu kwesistimu yakho yephampu entsha. Kodwa ngemva kokufakwa, ukusebenza kuyadumaza, futhi usola ibhodlela endaweni ethile emgqeni, mhlawumbe kusukela ku-valve yokuvala oyisebenzisile.

I-valve yebhola ingaba imbobo egcwele noma imbobo evamile. Ibhobo yembobo yembobo egcwele (imbobo) ifana nobubanzi bangaphakathi bepayipi ukuze kube nomkhawulo onguziro. Imbobo evamile ingusayizi wepayipi owodwa omncane.

Igama "ichweba eligcwele” (noma i-full bore) isici esithile somklamo, hhayi ikhwalithi yendawo yonke yawo wonke ama-valve ebhola. Ukwenza lo mehluko kuyisihluthulelo ekukhetheni ama-valve afanele. I-valve yembobo egcwele iklanyelwe ukusebenza kahle kakhulu kokugeleza. Imbobo yebhola inkulu kakhulu ukuze ifane nobubanzi bangaphakathi bepayipi exhunywe kulo. Ai-valve yembobo ejwayelekile, ngokuphambene, inembobo engusayizi owodwa omncane omncane kunepayipi. Lokhu kudala umkhawulo omncane.

Ngakho-ke, kufanele usebenzise nini ngayinye? Nali umhlahlandlela olula engiwunikeza ozakwethu.

Ezinhlelweni eziningi zansuku zonke, njengomugqa wegatsha oya kusinki noma indlu yangasese, i-valve yembobo ejwayelekile ilungile futhi ibiza kakhulu. Kodwa emgqeni omkhulu wamanzi noma ukuphuma kwepompo, i-valve yembobo egcwele ibalulekile ukuze kugcinwe ukucindezela nokugeleza.

Iyini i-valve yebhola ye-PVC?

Udinga indlela elula nethembekile yokumisa amanzi. Amavalvu esango esitayela sakudala ayaziwa ngokubamba noma avuze uma uwavala, futhi udinga ivalvu esebenza njalo.

I-valve yebhola ye-PVC iyi-valve yokuvala esebenzisa ibhola elijikelezayo elinembobo phakathi kwalo. Ukujika kwekota okusheshayo kwesibambo kuqondanisa imbobo nepayipi ukuze ilivule noma iliphendule ngokumelene nokugeleza ukuze ilivimbe.

II-valve yebhola ye-PVCidumile ngobulula bayo obuhle nokwethembeka okumangalisayo. Ake sibheke izingxenye zayo eziyinhloko. Iqala ngomzimba oqinile we-PVC obamba yonke into ndawonye. Ngaphakathi kuhlezi inhliziyo yevalvu: ibhola le-PVC eliyindilinga elinembobo ebhobozwe ngokunemba, noma "ibhobo," phakathi nendawo. Leli bhola lihlala phakathi kwezindandatho ezimbili ezibizwa ngezihlalo, ezenziwe ngazoI-PTFE (impahla edume ngegama layo lomkhiqizo, i-Teflon). Lezi zihlalo zidala isivalo esingangenisi amanzi ebholeni. Isiqu sixhuma isibambo esingaphandle nebhola elingaphakathi. Uma uphendulela isibambo ngamadigri angu-90, isiqu sizungeza ibhola. Ukuma kwesibambo njalo kukutshela ukuthi i-valve ivuliwe noma ivaliwe. Uma isibambo sihambisana nepayipi, sivulekile. Uma i-perpendicular, ivaliwe. Lo mklamo olula, ophumelelayo unezingxenye ezimbalwa ezihambayo, yingakho uthenjwa ezinhlelweni ezingenakubalwa emhlabeni jikelele.

Uyini umehluko phakathi kwe-L port kanye ne-T port ball valves?

Iphrojekthi yakho idinga ukuthi uphambukise amanzi, ungagcini nje ngokuwamisa. Uhlela inethiwekhi eyinkimbinkimbi yamapayipi nama-valve, kodwa unomuzwa wokuthi kufanele kube nesixazululo esilula, esisebenza kahle.

Imbobo engu-L kanye nembobo ye-T ibhekisela ekumeni kwe-bore ku-valve yebhola yezindlela ezi-3. Imbobo engu-L idlulisa ukugeleza phakathi kwezindlela ezimbili, kuyilapho imbobo ye-T ingaphambukisa, ixube, noma ithumele ukugeleza kuqonde kuyo.

Uma sikhuluma ngamachweba we-L kanye ne-T, sihamba ngaphezu kwama-valve alula wokuvula/ukuvala futhi singeneama-valve anezimbobo eziningi. Lezi zenzelwe ukuphatha isiqondiso sokugeleza. Ziwusizo ngendlela emangalisayo futhi zingashintsha ama-valve amaningana ajwayelekile, zonga isikhala nemali.

I-L-Port Valves

I-valve ye-L-port ine-bore emise okwe-“L.” Ine-inlet emaphakathi kanye nezindawo zokuphuma ezimbili (noma ama-inlet amabili kanye ne-outlet eyodwa). Isibambo sisendaweni eyodwa, ukugeleza kusuka maphakathi kuye kwesokunxele. Ngokujika okungama-degree angu-90, ukugeleza kusuka phakathi nendawo kuye kwesokudla. Indawo yesithathu ivimba konke ukugeleza. Ayikwazi ukuxhuma zonke izimbobo ezintathu ngesikhathi esisodwa. Umsebenzi wayo ukuphambukisa kuphela.

I-T-Port Valves

A I-valve ye-T-portiguquguquka. Ibhobo layo limise okwe "T." Ingenza yonke into engenziwa yi-L-port. Nokho, inendawo yesibambo eyengeziwe evumela ukuthi igeleze iqonde kumachweba amabili aphambene, njengevalvu yebhola evamile. Kwezinye izindawo, ingakwazi ukuxhuma zonke izimbobo ezintathu ngesikhathi esisodwa, okuyenza ilungele ukuhlanganisa uketshezi olubili endaweni eyodwa.

Ingabe ama-valve amapulaki agcwele imbobo?

Ubona olunye uhlobo lwevalvu yekota-turn ebizwa ngokuthi i-plug valve. Ibukeka ifana ne-valve yebhola, kodwa awunaso isiqiniseko sokuthi isebenza kanjani ngokuya ngokugeleza noma ukwethembeka kwesikhathi eside.

Njengama-valve ebhola, ama-valve epulaki angaba yimbobo egcwele noma imbobo encishisiwe. Kodwa-ke, ukwakheka kwazo kudala ukungqubuzana okwengeziwe, kuzenze kube nzima ukuphenduka futhi kube lula ukunamathela ngokuhamba kwesikhathi kune-valve yebhola.

Lesi isiqhathaniso esithokozisayo ngoba sigqamisa ukuthi kunganiama-valve ebholasebegqame kakhulu embonini. Aipulaki valveisebenzisa ipulaki eyi-cylindrical noma e-tapered enembobo kuyo. I-valve yebhola isebenzisa i-sphere. Zombili zingaklanywa ngokuvula ichweba eligcwele, ngakho-ke kuleyo ndaba, ziyafana. Umehluko omkhulu endleleni ezisebenza ngayo. Ipulaki ku-valve yepulaki inendawo enkulu kakhulu engaphezulu ehlala ithintana nomzimba we-valve noma ulayini. Lokhu kudala ukungqubuzana okuningi, okusho ukuthi kudinga amandla engeziwe (torque) ukujika. Lokhu kungqubuzana okuphezulu kwenza kube lula ukubamba uma kungasetshenziswa njalo. I-valve yebhola, ngakolunye uhlangothi, ivala ngezihlalo ze-PTFE ezincane, ezihlosiwe. Indawo yokuxhumana incane kakhulu, okuholela ekubambisaneni okuphansi nokusebenza kahle. Kwa-Pntek, sigxila ekwakhiweni kwe-valve yebhola ngoba ihlinzeka ngokuvaleka okuphezulu ngomzamo omncane kanye nokwethembeka okukhulu kwesikhathi eside.

Isiphetho

Akuwona wonke ama-valve ebhola e-PVC anembobo egcwele. Njalo khetha imbobo egcwele yamasistimu okugeleza okuphezulu kanye nembobo evamile yokuvalwa okujwayelekile ukuze uthuthukise ukusebenza nezindleko zezidingo zakho ezithile.
