Ama-valve ensimbi engagqwali afaneleka kakhulu ukuthi asetshenziswe kumapayipi agqwalayo namapayipi esitimu. Zinezici zokumelana nokugqwala, ukumelana nokushisa okuphezulu nokumelana nokucindezela okukhulu. Ngokuvamile asetshenziswa kumapayipi agqwalayo ezitshalweni zamakhemikhali, namapayipi emanzini kampompi noma ezitshalweni zokudla. Amavalvu ensimbi ekhabhoni awakwazi ukumelana nokugqwala futhi angasetshenziswa kuphela kumapayipi aphakathi nendawo angagqwali njengesitimu, uwoyela, amanzi, njll. Izindleko zamavalvu ensimbi ye-carbon ziphansi kakhulu kunezensimbi engagqwali, ngakho ngokuvamile awekho isitimu esigqwalayo nokunye. amapayipi asetshenziswa. Kusetshenziswa insimbi ye-carbon, futhi amavalvu ensimbi engagqwali nezinye izinto zisetshenziselwa ukugqwala. Okulandelayo incazelo emfushane yokukhethwa kwesicelo se-stainless steel inter-valve kanye ne-carbon steel gate valve nge-NSW Valve:
1 Yini isizathu sokuvuza kwe-carbon steel valve
I-Carbon steel gate valve iyi-valve yezimboni, esetshenziswa kabanzi ku-petroleum, amakhemikhali, esiteshini samandla nakwezinye izimboni. Inezinzuzo zokuzenzakalela, ukusebenza okulula, nempilo ende yesevisi, kodwa uma usebenzisa
Phakathi nenqubo, ngenxa yethonya layo noma izici zangaphandle, i-valve yesango le-carbon steel izovuza. Ngakho-ke, siyini isizathu sokuvuza kwe-valve yesango le-carbon steel? Amaphuzu asemqoka ami kanje
izizathu ezivamile.
1. Ukunemba okuphansi kokucutshungulwa kwendandatho yokuvala emise okukanxantathu kuholela ekuvuzeni kwangaphakathi kwevalvu yesango lensimbi ye-carbon. Uma nje i-valve yesango yomkhiqizo omkhulu ikhethiwe, ikhwalithi yezingxenye ezisele ngokuvamile iba ngcono, ukuze ukunemba kokucubungula kwendandatho yokuvala kungabi phansi.
1. Ukukhiqizwa okungazinzile kanye nezimo zokusebenza kuholela ekuvuzeni kwangaphakathi kwe-valve yesango. I-valve yesango inezidingo eziphakeme kakhulu endaweni yokusebenza. Uma indawo yokucindezela kanye nezinga lokushisa ingazinzile futhi ububanzi bokushintsha bukhulu kakhulu, ukucindezela komthelela kwendandatho yokuvala kuyoba kukhulu, okulula kakhulu. I-deformation iyenzeka, ekugcineni iholele ekuvuzeni kwe-valve.
3. Izinga lokulondoloza elimpofu le-valve liholela ekuvuzeni kwangaphakathi kwe-valve yesango. Abanye abasebenzi abayihlanzi indawo yokuvala iringi lapho belungisa i-valve. Ukuba khona kokungcola kuzothinta ukusebenza kwe-valve. Ngokuhamba kwesikhathi, indawo yokuvala izoklwejwa, okuzoholela ekuvuzeni kwe-valve.
4. Indandatho yesivikelo emise okwe ukugqwala ibangela ukuthi i-valve yesango ivuze isikhathi eside. Ngaphansi kwethonya le-medium, indandatho yokuvala i-corrored kalula. Uma ukugqwala kufinyelela ezingeni elithile, indandatho yokuvala izobikwa, ukuze i-valve ivuze.
5. Umzimba we-valve unesici. Uma umzimba we-valve unezinkinga ezifana nama-pores, i-slag inclusions, imifantu, izimbobo zesihlabathi, njll, khona-ke i-valve yesango ijwayele ukuvuza kwangaphandle ngesikhathi sokusetshenziswa.
Ngamafuphi, ukuvuza kwe-carbon steel gate valve kuyinkinga evamile. Uma kukhona ukuvuza, kuzobeka engozini ukuphepha kwemishini nabasebenzi, ngakho-ke kuyadingeka ukuthola imbangela nokuxazulula inkinga ngesikhathi.
4 Ungakhetha kanjani i-valve yensimbi engenasici
Ihluke ku-valve yebhola ye-pneumatic evamile, i-valve ye-butterfly kagesi namanye amadivaysi e-valve, ukukhiqizwa kwesango akudingi ukulungisa ukugeleza kwe-fluid medium, kodwa kusebenza njengokunqanyulwa okugcwele nokugcwele epayipini.
Isango lokushintsha liyasetshenziswa. Ngakho-ke kukhona ama-valve esango ensimbi engenasici emakethe, yimuphi umkhiqizo onokwethenjelwa? Izici zama-valve esango lensimbi engenasici
Insimbi engagqwali yenziwe ngensimbi engagqwali. Insimbi engagqwali yekhwalithi ephezulu kanye nokwelashwa okungaphezulu kanye nezinto ezicishayo nezishisayo kwenza insimbi engagqwali ibe izingxenye ezinhle zokunqanda ukugqwala kanye nekhwalithi enhle.
I-Abrasion, ihlala isikhathi eside kakhulu. Ngakho-ke, i-valve yesango yensimbi engagqwali ivame ukusetshenziselwa ukulawula ukugeleza kwamakhemikhali, futhi ukuvalwa kwayo okuhle nokumelana nokugqwala kwenza kungabi lula ukuguguleka nokugezwa yi-medium.
Ukushisa okuphezulu nokucindezela okuphezulu indoda kungaqinisekisa nokusebenza okuhle kokubeka uphawu. Iyiphi i-valve yesango yensimbi engagqwali engcono
Kuthiwa i-valve yesango yensimbi engagqwali iyisisetshenziswa se-valve yezimboni, kodwa empeleni sinakwa kakhulu. Isibonelo, uma ukukhethwa kwe-valve yesango kungalungile, izingozi ezingalindelekile zingase zenzeke, ngakho ungenzi
I-valve yesango yensimbi engagqwali kufanele ihlolwe ingcindezi ngaphambi kokuphuma efektri. Lapho uthenga i-valve, ikhasimende kufanele futhi linqume ububanzi bokucindezela i-valve okudingeka imelane nayo kusengaphambili ukuze likhethe imodeli efanele kanye nokucaciswa kwayo.
Abakhiqizi abavamile baqine kakhulu futhi banembe ekuhlolweni kwengcindezi, ngakho-ke noma ngabe ikhwalithi yevalvu, impilo yesevisi, ukuphumelela kwezindleko, noma ukusebenza kokuphepha.
Kubaluleke kakhulu ukukhetha umenzi ojwayelekile nothembekile, futhi imikhiqizo yabakhiqizi abajwayelekile (i-NSW Valve) ivikeleke kakhulu.
Ikhasimende ngalinye linezidingo ezihlukene zamavalvu esango ensimbi engenasici eyomile. Ngokuphathelene namanani, ikhwalithi nokuvikelwa komkhiqizo, abakhiqizi abahlukene ngezinye izikhathi banomehluko osobala. Ngakho-ke, ukukhethwa kwabakhiqizi kufanele kucabangele izici ezihlukahlukene.
