1. I-COMMPACT BALL VALVE X9002 kufanele igcinwe ekamelweni elomile nelingena umoya, futhi zombili iziphetho zephaseji kufanele zivalwe.
2. Ama-valve agcinwe isikhathi eside kufanele ahlolwe njalo ukuze asuse ukungcola futhi asebenzise amafutha aphikisana nokugqwala endaweni yokucubungula.
3. Ngemuva kokufakwa, ukuhlolwa okuvamile kufanele kwenziwe, izinto zokuhlola eziyinhloko:
(1) Isimo sokugqoka sendawo yokuvala.
(2) Ukugqokwa kwemicu ye-trapezoidal yesiqu se-valve ne-valve stem nut.
(3) Ukuthi ukupakisha kuphelelwe yisikhathi futhi akuvumelekile, uma konakalisiwe, kufanele kushintshwe ngesikhathi.
(4) Ngemva kokuba i-valve isilungisiwe futhi yahlanganiswa, ukuhlolwa kokusebenza kokuvala kufanele kwenziwe.
Umsebenzi wokulungisa ngesikhathi sokujova i-valve grease
Ukugcinwa kwe-valve ngaphambi nangemva kwenqubo yokushisela kudlala indima ebalulekile ekukhiqizeni nasekusebenzeni kwe-valve.Ukugcinwa okulungile, okuhlelekile futhi okuphumelelayo kuzovikela i-valve, yenze i-valve isebenze ngokujwayelekile futhi yandise ukusetshenziswa kwe-valve.ukuphila.Ukugcinwa kwe-valve kungase kubonakale kulula, kodwa akunjalo.Kuvame ukushaywa indiva izici zomsebenzi.
1. Lapho i-valve ijova amafutha, inkinga yenani lomjovo wamafutha ngokuvamile ayinakwa.Ngemuva kokuthi isibhamu samafutha senziwe kabusha, opharetha ukhetha i-valve kanye nemodi yokuxhuma umjovo wamafutha, bese wenza umsebenzi womjovo wamafutha.Kunezimo ezimbili: ngakolunye uhlangothi, inani lomjovo wamafutha lincane, futhi umjovo wamafutha awanele, futhi indawo yokuvala uphawu igqoka ngokushesha ngenxa yokuntuleka kokugcoba.Ngakolunye uhlangothi, umjovo wamafutha amaningi udala imfucuza.Isizathu siwukuthi asikho isibalo samandla ahlukene okuvala ama-valve ngokwesigaba sohlobo lwama-valve.Umthamo wokuvala ungabalwa ngokusekelwe kusayizi we-valve nohlobo, bese kuthi inani elifanelekile lamafutha lingajovwa.
2. Uma i-valve igcotshwa, inkinga yokucindezela ngokuvamile ayinakwa.Ngesikhathi sokusebenza komjovo wamafutha, ingcindezi yomjovo wamafutha ishintsha njalo eziqongweni nasezigodini.Uma ingcindezi iphansi kakhulu, uphawu luyavuza noma lwehluleka, ingcindezi iphezulu kakhulu, imbobo yokujova ugrisi ivinjiwe, igrisi esigxivizweni iqinisiwe, noma indandatho yokuvala ikhiywe ngebhola le-valve nepuleti levalvu.Ngokuvamile, lapho ingcindezi yokujova igrisi iphansi kakhulu, amafutha ajovwe ageleza kakhulu angene ngaphansi kwesikhala sevalvu, okuvame ukwenzeka kumavalvu esango amancane.Uma ingcindezi yomjovo wamafutha iphezulu kakhulu, ngakolunye uhlangothi, hlola imbobo yomjovo wamafutha, uma imbobo yamafutha ivinjiwe, yishintshe;ngakolunye uhlangothi, uma igrisi iqinisiwe, sebenzisa uketshezi lokuhlanza ukuze uthambise ngokuphindaphindiwe igrisi yokuvala ehlulekile futhi ujove igrisi entsha ukuze uyishintshe..Ngaphezu kwalokho, uhlobo lwe-seal kanye nezinto zokubeka uphawu nazo zithinta ingcindezi yomjovo wamafutha.Amafomu ahlukene okuvala anezingcindezi ezihlukene zokujova amafutha.Ngokuvamile, ukucindezela komjovo kagrisi wezimpawu eziqinile kufanele kube uphawu oluguquguqukayo kakhulu.
3. Uma i-valve igcotshwa, qaphela inkinga ye-valve endaweni yokushintsha.I-valve yebhola ngokuvamile isendaweni evulekile ngesikhathi sokulungiswa.Ezimweni ezikhethekile, ikhethwa ukuthi ivalwe ukuze ilungiswe.Amanye ama-valve awakwazi ukuphathwa njengezindawo ezivulekile.I-valve yesango kufanele ivalwe ngesikhathi sokulungiswa ukuze kuqinisekiswe ukuthi amafutha agcwalisa i-groove yokuvala eduze nendandatho yokuvala.Uma ivuliwe, igrisi yokuvala izowela ngqo kumzila wokugeleza noma i-valve cavity, okubangela ukungcola.
4. Uma i-valve igcotshwa, inkinga yomphumela wokujova amafutha ngokuvamile ayinakwa.Ngesikhathi sokusebenza komjovo wamafutha, ingcindezi, umthamo womjovo wamafutha, nendawo yokushintsha konke kujwayelekile.Kodwa-ke, ukuze kuqinisekiswe umphumela womjovo we-valve grease, ngezinye izikhathi kuyadingeka ukuvula noma ukuvala i-valve ukuze uhlole umphumela wokugcoba ukuze uqinisekise ukuthi ingaphezulu lebhola le-valve noma isango lifakwe ngokulinganayo.
5. Uma ujova amafutha, naka inkinga yokukhipha amanzi e-valve emzimbeni kanye ne-plug pressure relief.Ngemuva kokuhlolwa kwengcindezi ye-valve, igesi kanye nomswakama emgodini we-valve we-valve evaliwe kuzokwanda ukucindezela ngenxa yokwanda kwezinga lokushisa elizungezile.Lapho ugrisi ujova, indle nokucindezela kufanele kukhishwe ukuze kube lula ukuqhubeka kahle komjovo wamafutha.Ngemva kokuba igrisi ijovwe, umoya nomswakama endaweni evalekile kushintshwa ngokuphelele.Yehlisa ingcindezi ye-valve cavity ngesikhathi, eqinisekisa nokuphepha kwe-valve.Ngemuva komjovo wamafutha, qiniseka ukuthi uqinisa ipulaki yokudonsa kanye ne-pressure relief plug ukuze uvimbele izingozi.
6. Uma ujova igrisi, naka inkinga yokuphuma kwamafutha afanayo.Ngesikhathi sokujova ugrisi ojwayelekile, indawo yokukhipha igrisi eseduze nendawo yokujova igrisi izophuma kuqala, bese iye endaweni ephansi, bese iye endaweni ephakeme ngemuva kowokugcina, bese ikhipha igrisi ngokulandelana.Uma ingalandeli imithetho noma ingakhiqizi amafutha, ifakazela ukuthi kukhona ukuvinjelwa, futhi ikususe ngesikhathi.
7. Lapho ujova igrisi, bheka futhi inkinga yokuguquguquka kobubanzi be-valve kanye nesihlalo sendandatho yokuvala.Isibonelo, kuma-valve ebhola, uma kukhona ukuphazamiseka kwendawo evulekile, umkhawulo wendawo ovulekile ungalungiswa ngaphakathi ukuze kuqinisekiswe ukuthi ububanzi buqondile futhi bukhiyiwe.Ukuze ulungise indawo yomkhawulo, akufanele ulandele indawo yokuvula noma yokuvala kuphela, kodwa kufanele ucabangele indawo yonke.Uma indawo yokuvula i-flush futhi indawo yokuvala ingekho, i-valve ngeke ivaleke ngokuqinile.Ngendlela efanayo, uma ukulungiswa kusendaweni, ukulungiswa okuhambisanayo kwendawo evulekile kufanele kucatshangelwe.Qinisekisa ukuhamba kwe-engeli efanele yevalvu.
8. Ngemuva komjovo wamafutha, imbobo yomjovo wamafutha kufanele ivalwe.Gwema ukungena kokungcola noma i-oxidation yama-lipids embobeni yomjovo wamafutha.I-anti-rust grease kufanele ifakwe embozweni ukuze ugweme ukugqwala.Ukuze isetshenziswe ekusebenzeni okulandelayo.
I-9.Nine, lapho ujova amafutha, kuyadingeka futhi ukucabangela ukwelashwa okuqondile kwezinkinga ezithile ekuthuthweni okulandelanayo kwemikhiqizo yamafutha esikhathini esizayo.Uma kubhekwa izimfanelo ezihlukene zedizili nophethiloli, ikhono lokubhoboza nokubola likaphethiloli kufanele licatshangelwe.Esikhathini esizayo sokusebenza kwe-valve, lapho uhlangabezana nokusebenza kwengxenye kaphethiloli, gcwalisa amafutha ngesikhathi ukuze uvimbele ukuguga.
10. Uma ujova igrisi, ungawuzibi umjovo wamafutha esiqwini sevalvu.Kukhona umkhono oshelelayo noma ukupakisha ku-valve shaft, nayo edinga ukugcinwa igcotshiwe ukuze kuncishiswe ukumelana nokungqubuzana ngesikhathi sokusebenza.Uma ukugcoba kungenakuqinisekiswa, i-torque izokhula ngesikhathi sokusebenza kukagesi futhi izingxenye zokugqoka zizoba nzima ngesikhathi sokusebenza ngesandla.
11. Amanye ama-valve amabhola amakwe ngemicibisholo emzimbeni wevalvu.Uma kungekho ukubhala kwe-FIOW yesiNgisi, isiqondiso sesenzo sesihlalo sokuvala, esingasetshenziswa njengenkomba yesiqondiso sokugeleza kwe-medium, futhi isiqondiso sokuzikhipha kwe-valve siphambene.Ngokuvamile, i-valve yebhola evalwe ngezihlalo ezimbili inesiqondiso sokugeleza se-bidirectional.
12. Uma ugcina i-valve, qaphela ukungena kwamanzi ekhanda likagesi kanye nendlela yokudlulisela.Ikakhulukazi imvula engena ngesikhathi sezimvula.Enye iwukugqwala umshini wokudlulisa noma umkhono we-shaft wokudlulisa, kanti enye iwukuba yiqhwa ebusika.Yenza ukuba i-torque ibe nkulu kakhulu uma ivalvu kagesi isebenza, futhi ukulimala kwezingxenye zokuhambisa kuzobangela ukuthi injini yehliswe noma *ukuvikela kwetorque kuzowiswa futhi ukusebenza kukagesi kungenzeki.Izingxenye zokudlulisela zonakele, futhi ukusebenza okwenziwa ngesandla akukwazi ukwenziwa.Ngemuva kokuthi *ukuvikelwa kwe-torque kwenziwe kusebenze, ukusebenza okwenziwa ngesandla nakho akukwazi ukushintshwa.Ukusebenza ngenkani kuzolimaza izingxenye ze-alloy zangaphakathi.
