Izimbangela Zokwehluleka Kwesihlalo Se-Valve kanye Neziphakamiso Zokuthuthukiswa Kwesakhiwo
Ngemva kokwenza amaphrojekthi e-valve kule minyaka, uma ngikhuluma iqiniso, ngibone amacala amaningi kakhulu ezinkinga zesihlalo se-valve. Esikhathini esiningi, umsebenzisi ukhononda ngokuvuza kwe-valve, empeleni, akuyona inkinga ye-spool, kodwa isihlalo se-valve sesigugile isikhathi eside. Ngezinye izikhathi impahla ayilungile, ngezinye izikhathi isakhiwo somklamo asizange sicabangele izimo zokusebenza.
Ngaphambilini sifake ama-valve ebhola lesitshalo sokuphekela, imidiya enothuli, izinga lokushisa eliphezulu, imidwebo yomklamo ebhalwe esihlalweni esithambile sensimbi engagqwali, imiphumela yokusebenza okungaphansi kwengxenye yonyaka, ukuvakasha kokubuya kwathola ukuthi amayunithi amaningana okuvuza okukhulu kwangaphakathi. Sihlukanise futhi sathola ukuthi indandatho yokuvala ikhuhliwe, unqenqema lwesihlalo se-valve nalo luwile kancane. Kamuva sathathelwa indawo yisihlalo se-valve sensimbi esihlanganisiwe esiqinile, impilo yanda ngeminyaka engaphezu kwemibili.
Kunezindlela eziningana ezivamile zokuhluleka: enye ukuguguleka kobuso bokuvala, ikakhulukazi ngezinhlayiya eziqinile zemidiya, ukuvulwa nokuvalwa okuvama kakhulu ngaphansi kokuklwebheka ngokushesha okukhulu; eyesibili ukuklwebheka kwesendlalelo se-weld, okuwukuthi inqubo yokubeka phezulu ayikho noma ukucindezeleka kokwelashwa kokushisa akukhululiwe; kukhona futhi inkinga efihliwe ukuthi i-spool kanye ne-set assembly akugxilile, umphumela uba ukuthi uhlangothi olulodwa lohlobo oludala, uhlangothi olulodwa lokuvuza.
Uma isigaba sokuklama singasithathi ngokungathi sína isihlalo se-valve, izinkinga cishe azinakugwenywa. Sinekhasimende emgqeni wokukhiqiza i-alumina elinama-valve amaningi e-V-ball, isihlalo se-valve siyinsimbi engagqwali evamile, sisebenza isikhathi esingaphansi konyaka ekucindezelweni, ukuhlanza akukwazi ukuhlanzwa. Kamuva, sabanika inguqulo ye-taper ukuze baqinise isakhiwo, sanezela umkhawulo we-bevelled kanye nomsele wokusekela wangaphakathi, sisebenza iminyaka emibili ngaphandle kokuguga okukhulu.
Ngokwesakhiwo, kunconywa ukuthi umklamo ucabangele amaphuzu amathathu: Okokuqala, indawo yokuvala ngangokunokwenzeka ukuze ithathelwe indawo, ingalungiswa endaweni; Okwesibili, izinto zingafakwa ezingxenyeni zokushisela futhi ungafisi ukusindisa izinkinga ngensimbi engagqwali eyodwa; Okwesithathu, ukuhlanganiswa kanye nomkhawulo wokugxila, ungathembeli ekuqondeni ngesandla ukuze kuhlangane. Ngaphandle kwalokho, uma ukuphambuka okuncane kokufakwa, shintsha izikhathi ezimbalwa ngemuva kokuqala 'kwe-spool yokugedla'.
Esimweni sesihlalo se-valve esisenzile, njengokuhlanganiswa kwe-metal bevelled limit + insert composite sealing, ukusebenza kuzinzile kakhulu ezimweni zokusebenza ze-coal oil, i-ammonium phosphate, i-high salt waste liquid. Manje amakhasimende amaningi afake ngqo isakhiwo sethu esenziwe ngokwezifiso kumaphakheji awo obuchwepheshe, okubonisa ukuthi lolu hlobo lwesisombululo lungaxazulula izinkinga ensimini.
Isihlalo se-valve siyinto okungekho muntu oyinakayo lapho eklama, futhi uma kukhona okungahambi kahle, kuyinto enkulu. Phakamisa ukuthi wonke umuntu aklame, enze ozakwabo bokuthenga, angabheki nje ishidi ledatha, alalele ukusebenza kwensimu nokugcinwa kwabantu ukuthi bathini. Ngenxa yokuthi izimo zokusebenza azilindi abantu, isakhiwo sihle, sifakwe izinyanga ezintathu ukuze sazi.
