Ama-valve ebholayizakhi ezibalulekile ezinhlelweni zesimanje zokulawula uketshezi, ezaziwa ngokuqina kwazo, ukuthembeka kanye nokusebenza kahle. Intuthuko yabo iguqule izimboni ezahlukahlukene, kusukela kumapayipi kanye nokucolisiswa kawoyela ekusebenzeni kwamakhemikhali kanye nokukhiqizwa kwamandla. Kepha lokhu kusungulwa ngobuhlakani kwavelaphi? Ukuqonda umlando wama-ball valves kuhlinzeka ngokuqonda kokuthi intuthuko yezobunjiniyela ibuye kanjani umhlaba we-fluid dynamics.
Umqondo wokulawula ukugeleza kwamanzi uketshezi emuva kwezinkulungwane zeminyaka. Impucuko yasendulo, kufaka phakathi amaRoma namaGrikhi, athuthukise ama-valve ama-valve ukuze alawule ukwabiwa kwamanzi. Lawa madivayisi okuqala, ngokujwayelekile isango noma ama-valves ama-plug, ayelula kepha ajwayele ukuthambekela ukuvuza, ukugqoka, nokungasebenzi kahle.
Ukucinga kwezindlela ezingcono ze-valve kuqhubeke kuyo yonke iminyaka ephakathi nendawo nasekuguqukeni kwezimboni. Ngesidingo esandayo sokulawulwa kokugeleza okusebenzayo nokuvuzayo ezimbonini ezinjengamandla weSteam kanye nokukhiqizwa kwamakhemikhali, onjiniyela bafuna ukuthuthuka emiklamo ye-valve yendabuko.
Ukusungulwa kwe-valve yebhola yesimanje kungalandelelwa emuva ngekhulu lama-20. Ngenkathi umthofu oqondile uhlala ungacacile, imiklamo yakuqala yavela ngawo-1870s, kepha ayimukelwa kabanzi ngenxa yokulinganiselwa kwezinto ezibonakalayo. Kwakungekho kuze kube maphakathi nekhulu lama-20 lapho ama-ball valves abona intuthuko ebalulekile.
Ngawo-1940s, ama-Industrial Innovations ezintweni zokwakha nasekukhiqizweni kwavuma onjiniyela ukuthi bahlaziye ukwakheka kwe-valve yebhola. Ukwethulwa kwe-polymers zokwenziwa, ikakhulukazi i-teflon (PTFE), inike amandla ukudalwa kwezimpawu ezihlala isikhathi eside, ezivuzayo zobufakazi obuthuthukisiwe kakhulu. Lokhu kuphumelela kuholele ekusetshenzisweni kabanzi kweama-valve ebholaezihlolweni zezimboni.
Design and ukusebenza
I-valve yebhola iqukethe i-hollow, sphere eyenziwe (ibhola) elijikeleza ngaphakathi kwezindlu ukulawula ukuhamba kwamanzi. Lapho i-valve ivuliwe, umgodi ebhola uqondanisa nepayipi, okuvumela uketshezi ukuthi ludlule. Lapho kuvalwa, ingxenye eqinile yebhola ivimba le ndima, ivale ukugeleza ngokuphelele. Le ndlela elula nokho ephumelelayo inikezela ngezinzuzo eziningana ngaphezulu kwesango lendabuko noma ama-valves omhlaba, kufaka phakathi:
● Ukusebenza okusheshayo nokulula (imvamisa ngesibambo se-quarter)
● Ukuvuza okuncane ngenxa yezakhiwo eziqinile zokubopha
● Ukuqina okuphezulu kanye nokumelana nokucindezela kwengcindezi nokungafani kokushisa
● Idizayini ethambile enezidingo zokulungiswa okuphansi
Izicelo zanamuhla kanye nentuthuko
Kusukela ethandwa ngayo maphakathi nekhulu lama-20,ama-valve ebholabavele bahlangabezana nezidingo zezimboni ezahlukahlukene. Manje sebesetshenziswa ku:
● Amapayipi kawoyela negesi wokulawula uwoyela ongahluziwe kanye nokugeleza kwegesi yemvelo
● Izitshalo zokwelashwa kwamanzi ukuze zilawule izinhlelo ezihlanzekile nezingcolile
● Imboni yezemithi nokudla lapho izimo zokuhlanzeka zibalulekile
● Izinhlelo ze-HVAC nezinhlelo zamapayipi zomthethonqubo oqondile
Ukuthuthuka kwezobuchwepheshe kuyaqhubeka nokwenza ngcono ukwakhiwa kwe-Ball Valve. Namuhla, ama-valves webhola azenzakalelayo futhi ahlakaniphile ahlomele izinzwa namakhono okulawulwa kude aqala ngezinto ezijwayelekile kuzilungiselelo zezimboni, ezandisa ukusebenza kahle nokuphepha.
Le khasiI-Ball valveIngabe i-testament ekuhlakanipheni komuntu e-Engineering kanye nokulawulwa koketshezi. Kusukela emiklamweni yayo yokuqala ebonakalayo ngekhulu le-19 kuya kwezinguqulo ezisebenza kahle futhi ezithembekile esizisebenzisayo namuhla, lokhu okusha kudlale indima ebalulekile ekuthuthukisweni kwezimboni. Njengoba ubuchwepheshe buqhubeka, ama-ball valves azoqhubeka nokuvela, athuthukise futhi athuthukise ukusebenza kwawo kanye nokuguquguquka kwezinto eziguquguqukayo ezimbonini zomhlaba.
