Ukulimala kwe-valve yokuvalwa kwendawo kubangela i-valve ye-butterfly check valve

Ukulimala kwe-valve yokuvalwa kwendawo kubangela i-valve ye-butterfly check valve

Ngenxa yokubekwa uphawu esiteshini se-valve idlala i-truncation nokufinyelela, ukulawulwa nokusabalalisa, ukuhlukaniswa nokuxubana kwemidiya, ngakho-ke indawo yokubeka uphawu ivame ukuthonywa ukugqwala, ukuguguleka, ukugqoka, ukulimaza kalula.
Imbangela yokulimala kobuso obuvaliwe ukulimala komuntu kanye nokulimala kwemvelo. Ukulimala kokwenziwa kubangelwa izici ezifana nokuklama okungalungile, ukukhiqizwa okungalungile, ukukhetha okungalungile kwempahla, ukufakwa okungalungile, ukusetshenziswa kabi kanye nokugcinwa okungalungile. Ukulimala kwemvelo ukuguga kwe-valve ngaphansi kwezimo ezijwayelekile zokusebenza, kanye nomonakalo obangelwa ukugqwala okungenakugwemeka nokuguguleka kwendawo evalekayo yi-medium.
Izimbangela zokulimala kwendawo yokubeka uphawu zingafingqwa ngale ndlela elandelayo.
Ikhwalithi yomshini wokuvala insimbi yimbi, ikakhulukazi ekhonjiswa endaweni evalekayo njengokuqhekeka, ukwakheka kwe-porosity kanye nokwakheka kwe-clamp, kungenxa yokukhetha okungafanele kanye nokubekelwa phansi kwe-welding kanye nokucaciswa kokwelashwa kokushisa ngesikhathi sokusebenza kwe-welding kanye nokwelashwa kokushisa, okubangelwa ubulukhuni bendawo yokuvala uphawu buphezulu kakhulu noma buphansi kakhulu, kungenxa yokwehluleka kwempahla engalungile noma ukwelashwa okushisa, ukuvala ubuso obuqinile obungalingani, ukumelana nokugqwala, Kubangelwa ikakhulukazi ukuvuthela insimbi engezansi phezulu lapho kwenziwa ingxubevange kanye nokuhlambulula ingxubevange. ukwakheka kwendawo yokubeka uphawu. Yiqiniso, zikhona izinkinga zokuklama.
Umonakalo odalwe ukukhetha nokusebenza okungafanele. Ukusebenza okuyinhloko ukuthi i-valve ayikhethiwe ngokuvumelana nezimo zokusebenza, futhi i-valve yokusika isetshenziswa njenge-valve ye-throttle, okuholela ekucindezelweni okukhethekile okuvala kakhulu nokuvala okusheshayo noma ukuvala okuxekethile, ukuze indawo yokuvala uphawu. iyaguguleka futhi igugile.
Ukufakwa okungafanele kanye nokugcinwa okungalungile kuholela ekusebenzeni okungavamile kwendawo yokuvala, futhi i-valve isebenza ngesifo, esilimaza indawo yokuvala ngaphambi kwesikhathi.
Ukugqwala kwamakhemikhali okuphakathi, okuphakathi nendawo okuzungeze indawo yokuvala uma kungekho mshini wamanje, okuphakathi kudlala indima yamakhemikhali ngokuqondile ngendawo yokuvala, ukugqwala kwendawo yokuvala.
Ukugqwala kwe-Electrochemical, ukubekwa uphawu kokuxhumana okungaphezulu komunye nomunye, indawo yokuvala kanye nokuxhumana komzimba ne-valve evaliwe, umehluko wokuhlushwa okuphakathi, umehluko wokuhlushwa komoya-mpilo nezinye izizathu, kuzoveza umehluko ongaba khona, ukugqwala kwe-electrochemical, okuholela ohlangothini lwe-anode lokugqwala kwendawo yokuvala uphawu.
Ukuguguleka kwe-medium kuwumphumela wokuhuzuka, ukuguguleka kanye ne-cavitation yendawo yokuvala lapho okuphakathi kugeleza. Imaphakathi ngesivinini esithile, izinhlayiya ezinhle ezimaphakathi zinomthelela endaweni yokuvala, ukuze kubangele umonakalo wendawo, ukugeleza kwesivinini esikhulu se-medium kukhahla ngokuqondile indawo yokuvala, ukuze kubangele umonakalo wendawo, ukugeleza okuxubile okuphakathi kanye nokuhwamuka kwendawo, umthelela wokuqhuma kwebhamuza endaweni evalekayo, okubangela umonakalo wendawo. Ukuguguleka kwendawo emaphakathi kanye nomthelela oshintshanayo wokugqwala kwamakhemikhali kuzoguguleka kakhulu indawo evalekile.
Ukulimala kwemishini, indawo evalekayo ekuvuleni nasekuvaleni kwe-US kuzoveza ukuhuzuka, ukuqhuqha, ukuminyanisa nomunye umonakalo. Phakathi kwezindawo ezimbili zokuvala uphawu, ngaphansi kwesenzo sokushisa okuphezulu nokucindezela okukhulu, ama-athomu angena komunye nomunye, okuholela entweni yokunamathela. Lapho izindawo ezimbili zokuvala zinyakaza, ukunamathela kulula ukudabula. Uma buphakeme ubulukhuni bobuso bendawo yokuvala, maningi amathuba okuba le nto yenzeke. I-valve enqubweni yokuvala, i-disc ye-valve ohlelweni lokubuyela esihlalweni izolimaza futhi incinde indawo yokuvala, ukuze indawo yokuvala igqoke noma i-indentation yendawo.
Ukulimala kokukhathala, indawo yokuvala ukusetshenziswa kwesikhathi eside, ngaphansi kwesenzo somthwalo oshintshanayo kubangele ukukhathala kwendawo evalayo, ukuqhekeka nokuxebuka kongqimba. Irabha nepulasitiki ngemuva kokusetshenziswa isikhathi eside, kulula ukukhiqiza into yokuguga, okuholela ekusebenzeni kabi.
Kusukela ekuhlaziyweni okungenhla kwezimbangela zokulimala kwendawo yokuvala uphawu, kungabonakala ukuthi ukuthuthukisa ikhwalithi kanye nempilo yesevisi yendawo yokuvala i-valve, kuyadingeka ukukhetha izinto ezifanele zokuvala uphawu (bheka isigaba sezinto ezibonakalayo), isakhiwo sokuvala esinengqondo nezindlela zokucubungula.
I-Butterfly HLOLA i-valve I-valve yokuhlola uvemvane ivulwa ngokucindezela kwento ephakathi ukuze inqobe amandla okunyakazisa entwasahlobo, futhi ivalwe umzuzu wokugobhoza okhiqizwa intwasahlobo, bese kuba ngokucindezela kwendawo ephakathi ukukhiqiza ukucindezela kokuvala ukuze kuvaleke. . Ekusetshenzisweni, kufanele kuqashelwe ukuthi kukhona umsindo ongavamile nokudlidliza kwe-valve. Ukuze uvimbele ukwakheka komphumela wesando samanzi epayipini, kufanele kuqashelwe ukuguquguquka kwengcindezi ephakathi kwamapayipi. Ukugcinwa kwesikhathi eside kwe-valve kufanele kuhlolwe njalo, *** ukungcola. Ukunakwa okukhethekile kufanele kukhokhwe ekuhlanzweni kwendawo yokuvala ukuvimbela ukulimala kwendawo yokubeka uphawu. Ngaphambi kokufaka, hlola ngokucophelela ukuthi uphawu lwe-valve luhambisana nezidingo zokusetshenziswa.

Isakhiwo sesi-3.
3.1 Isakhiwo esiyisisekelo sevalve yokuhlola uvemvane sikhonjisiwe kuMfanekiso 1
4. Isebenza kanjani
I-BUTTERFLY CHECK VALVE IVULWA NGOKUCINDEZELEKA KOMphakathi ukuze kunqotshwe amandla e-torsional entwasahlobo, futhi ivalwe umzuzu we-TORsional okhiqizwa entwasahlobo, bese kuba yingcindezi ye-medium ukukhiqiza ukucindezela kokuvala ukuze kuvalwe.
5. Ukugcinwa, ukugcinwa, ukufakwa kanye nokusetshenziswa
5.1 Ivalvu kufanele igcinwe ekamelweni elomile nelingena umoya, futhi amaphethelo womabili wephaseji yevalvu ayovinjwa.
5.2 Amavalvu agcinwe isikhathi eside kufanele ahlolwe njalo ukuthi angcolile yini. Ukunakwa okukhethekile kufanele kukhokhwe ekuhlanzweni kwendawo yokuvala ukuvimbela ukulimala kwendawo yokubeka uphawu.
5.3 Ngaphambi kokufaka, hlola ngokucophelela ukuthi umaki wevalvu uyahambisana yini nezidingo zokusebenzisa.
5.4 Ngaphambi kokufakwa, igumbi elingaphakathi nendawo yokuvala ivalvu kufanele ihlolwe. Uma kukhona ukungcola, kufanele kuhlanzwe ngendwangu yokuhlanza.
5.5 Ngaphambi kokufakwa, kufanele kuqashelwe ukuthi uphawu lwesiqondiso sokugeleza ku-valve luhambisana nokugeleza kwe-medium.
5.6. Amavalvu okuhlola uvemvane angafakwa aqonde phezulu noma avundlile, kuye ngezimo zamapayipi.
5.7 Ngesikhathi sokusetshenziswa, kufanele kuqashelwe ukuthi kukhona umsindo ongavamile nokudlidliza kwevalvu. Ukuze uvimbele ukwakheka komphumela wesando samanzi epayipini, kufanele kuqashelwe ukuguquguquka kwengcindezi ephakathi kwamapayipi.
6. Amaphutha okungenzeka, izimbangela, kanye nezindlela zokuwaqeda kukhonjisiwe kuThebula 1
Ithebula 1 Amaphutha angenzeka, izimbangela, kanye nezindlela zokuxazulula izinkinga
Iwaranti engu-7.
Umkhiqizi unesibopho sewaranti yevalvu phakathi nonyaka owodwa ngemva kokusetshenziswa, kodwa kungakapheli izinyanga eziyi-18 ngemva kokulethwa. Ngesikhathi sewaranti, ngenxa yezizathu zekhwalithi yomkhiqizo ingakhandwa noma ishintshwe.
