Okwesithupha, uxhumano lwe-clamp:

Lena indlela yokuxhumana esheshayo edinga ama-bolts amabili kuphela futhi ifanele ama-valve okucindezela okuphansi avame ukususwa.

Okuyisikhombisa, ukuxhumana kwangaphakathi okuziqinisayo:

Amafomu okuxhumana angenhla, ukusetshenziswa kwamandla angaphandle ukuze kuncishiswe ukucindezela okuphakathi, ukufeza ukubekwa uphawu. Ukuxhumana okuziqinisayo usebenzisa ingcindezi ephakathi kuchazwe ngezansi. Indandatho yayo yokuvala ifakwe ku-cone yangaphakathi, ohlangothini oluphambene oluphakathi lube yi-Angle ethile, ukucindezela okuphakathi kuya ku-cone yangaphakathi, futhi idluliselwe kwendandatho yokuvala, nge-Angle ethile ye-cone, ikhiqize izingxenye ezimbili, eyodwa kanye ne-valve. umzimba I-Central Line ihambisana ngaphandle, enye ingcindezi eya odongeni lwangaphakathi lomzimba we-valve. Ingxenye yokugcina ingamandla aziqinisayo. Uma ukucindezela okuphakathi nendawo, kukhulu kakhulu amandla okuziqinisa. Ngakho lolu hlobo lokuxhuma lufanelekile kuma-valve aphezulu. Kungaphezu kokuxhumeka kwe-flange, ukusindisa izinto eziningi kanye nabasebenzi, kodwa futhi kudinga ukulayisha kuqala okuthile, ukuze ingcindezi ye-valve ingabi phezulu, ukusetshenziswa okuthembekile. Amavalvu enziwe ngomgomo wokuzivala wona ngokuvamile amavalvu okucindezela aphezulu. Kunezinhlobo eziningi zokuxhuma kwe-valve, njengama-valve amancane angadingi ukususwa, ahlanganiswe namapayipi; Amanye ama-valve angewona ama-metallic, ukusetshenziswa koxhumano lwesokhethi, njalonjalo. Abasebenzisi be-valve kufanele belashwe ngokuningiliziwe ngokuya ngesimo.

Izesekeli ezihlobene

Kukhona ama-valve nokufakwa, asetshenziswa ohlelweni lokuxhuma noma lokulawula lwamapayipi. Amavalvu nokufakwa akukwazi ukuba khona, kuyaphelelisana. Valve ukufakwa kukhona carbon steel nensimbi engagqwali, futhi PVC, noma ezinye izinto, evame ukusetshenziswa ezimbili zokuqala, eminyakeni yamuva kanye nenqubekelaphambili izinga lokuphila kwabantu, isidingo ukudla futhi kulandelwa enkulu. Ngakho-ke iqhuba ukuthuthukiswa okusheshayo kwemishini yokudla, ngakho okokufakwa kwamavalvu ensimbi engagqwali aphuma endaweni yezimboni, abantu bavame ukusho lokho okufakwayo kwamavalvu, ikakhulukazi okusansimbi engagqwali ibanga lokuhlanzeka.

Ukugcinwa komjovo wamafutha

Umsebenzi wokulungisa ochwepheshe we-valve ngaphambi nangemva kokukhiqizwa ngaphambi kokushisela udlala indima ebalulekile enkonzweni ye-valve ekukhiqizeni nasekusebenzeni. Ukugcinwa okunembile nokuhlelekile futhi okuphumelelayo kuzovikela i-valve, yenze i-valve isebenze ngokujwayelekile futhi yandise impilo yesevisi ye-valve. Ukugcinwa kwe-valve kungase kubonakale kulula, kodwa akunjalo. Kuvame ukushaywa indiva izici zomsebenzi.

Lapho i-valve grease ijovwa, inani lamafutha ngokuvamile alinakwa. Ngemuva kokuthi amafutha engeziwe, opharetha ukhetha i-valve kanye nemodi yokuxhuma amafutha futhi enze umsebenzi wamafutha. Kunezimo ezimbili: ngakolunye uhlangothi, inani lomjovo wamafutha lincane, futhi indawo yokubeka uphawu isheshiswa ukuntuleka kokugcoba. Ngakolunye uhlangothi, umjovo wamafutha udlulele, okuphumela ekubeni kusetshenziswe ngokweqile. Akuhambisani nohlobo lohlobo lwe-valve, umthamo wokuvala wama-valve ohlukile wokubala okunembile. Ingabalwa ngosayizi we-valve kanye nomthamo wokuvala uhlobo, bese kuba nenani elifanele lomjovo wamafutha.

Okwesibili, amafutha e-valve, ngokuvamile awanaki inkinga yokucindezela. Ngesikhathi sokusebenza komjovo wamafutha, ingcindezi yomjovo wamafutha ishintsha njalo eziqongweni nasezigodini. Uma ingcindezi iphansi kakhulu, uphawu luyavuza noma lwehluleke. Uma ingcindezi iphezulu kakhulu, imbobo yokugcwalisa amafutha ivinjiwe, i-grease esicini iqinisiwe, noma indandatho yokuvala ivaliwe ngebhola le-valve noma i-valve plate. Ngokuvamile lapho umfutho womjovo wamafutha uphansi kakhulu, amafutha amaningi afakwa ngaphansi kwegumbi le-valve, elivame ukwenzeka kumavalvu esango amancane. Uma ingcindezi yomjovo iphezulu kakhulu, ngakolunye uhlangothi, hlola i-nozzle yomjovo, bese uyishintsha uma ukuvinjelwa kwembobo yamafutha kunqunywa; Ngakolunye uhlangothi ukuqina kwe-lipid, ukusebenzisa uketshezi lokuhlanza, ukuthambisa ngokuphindaphindiwe ukwehluleka kwamafutha ophawu, nokujova ukushintshwa kwamafutha amasha. Ngaphezu kwalokho, uhlobo lokuvala kanye nezinto zokubeka uphawu, nazo zithinta ingcindezi yomjovo wamafutha, amafomu ophawu oluhlukile anengcindezi ehlukile yomjovo wamafutha, ngokuvamile, ingcindezi yomjovo wamafutha oqinile iphakeme kunophawu oluthambile.

Okwesithathu, lapho i-valve igcoba, qaphela i-valve endaweni yokushintsha. Ukugcinwa kwe-valve yebhola ngokuvamile kusesimweni esivulekile, izimo ezikhethekile zikhetha ukugcinwa okuvaliwe. Amanye ama-valve awakwazi ukwelashwa endaweni evulekile. Ivalvu yesango kufanele ibe sesimweni esivaliwe lapho ilungiswa, ukuze kuqinisekiswe ukuthi amafutha ahambisana nendandatho yokuvala ambozwe nge-groove yokuvala, uma evulekile, igrisi yokuvala izowela ngqo kumzila wokugeleza noma ekamelweni le-valve, okuholela ekusetshenzisweni ngokweqile.

Okwesine, i-valve grease, ngokuvamile ayinaki inkinga yomphumela wamafutha. Ukucindezela, inani lamafutha kanye nendawo yokushintsha emsebenzini wokujova igrisi kuvamile. Kodwa-ke, ukuze uqinisekise umphumela wamafutha we-valve, ngezinye izikhathi kuyadingeka ukuvula noma ukuvala i-valve, hlola umphumela wokugcoba, futhi uqinisekise ukugcotshwa okuphakathi kwebhola le-valve noma indawo yenqama.

Okwesihlanu, amafutha, kufanele anake i-valve body blowdown kanye nezinkinga zokukhulula ingcindezi yokuxhunywa kwentambo. Ngemuva kokuhlolwa kwengcindezi ye-valve, igesi namanzi egumbini le-valve legumbi lokuvala kuzonyusa ukucindezela ngenxa yokwanda kwezinga lokushisa elizungezile. Ngesikhathi somjovo wamafutha, ukukhululeka kwengcindezi kufanele kuthuthukiswe ukuze kube lula ukujova okubushelelezi kwamafutha. Ngemuva komjovo wamafutha, umoya namanzi endaweni yokuvala kushintshwa ngokuphelele. Ukukhululwa ngesikhathi sokucindezela kwegumbi le-valve, kodwa futhi nokuqinisekisa ukuphepha kokusetshenziswa kwe-valve. Ngemuva komjovo wamafutha, qiniseka ukuthi uqinisa ipulaki yentambo yokupholisa phansi kanye neyokusiza ukucindezela ukuvimbela izingozi.

Okwesithupha, umjovo wamafutha, kufanele sinake inkinga yesilinganiso samafutha. Ngesikhathi somjovo ojwayelekile wamafutha, imbobo yamafutha eduze komlomo womjovo wamafutha esikhawu iyokuqala ukukhiqiza amafutha, bese kuthi endaweni ephansi, i-**le ibe yindawo ephezulu, futhi amafutha akhiqizwa ngokulandelana. Uma kungenjalo ngokusho komthetho noma cha amafutha, kuqinisekiswa ukuthi kukhona ukuvinjelwa, ukwelashwa okufika ngesikhathi.

Okwesikhombisa, amafutha kufanele futhi abheke ububanzi be-valve kanye nenkinga yokushaywa kwesihlalo sendandatho yokuvala. Isibonelo, i-valve yebhola, uma kukhona ukuphazamiseka okuvulekile, ingashintshwa kumkhawulo ovulekile, uqinisekise ububanzi obuqondile ngemva kokukhiya. Lungisa umkhawulo hhayi nje ukuphishekela isikhundla esiseceleni esivulekile noma esiseduze, ukuze ucabangele konke. Uma indawo yokuvula ishaywa futhi ingavalwanga endaweni, izokwenza ukuthi i-valve ivaleke ngokukhululekile. Ngokufanayo, lungisa ukuvala endaweni, kodwa futhi ucabange ukulungiswa okuhambisanayo kwendawo evulekile. Qinisekisa ukuthi i-valve ine-Engeli elungile stroke.

Okwesishiyagalombili, emva kokujova amafutha, qiniseka ukuthi uyavala umlomo womjovo wamafutha. Gwema ukungena kokungcola noma i-lipid oxidation emlonyeni womjovo wamafutha. Isembozo kufanele sigcotshwe ngamafutha avimbela ukugqwala ukuze kugwenywe ukugqwala. Okokukhohlisa okulandelayo.

Okwesishiyagalolunye, umjovo wamafutha, kodwa futhi ukucatshangelwa ekudluliseni okulandelanayo kwamafutha okuzayo kwezihloko ezinemininingwane ngokuningiliziwe. Njengoba kunikezwe izimfanelo ezihlukene zikadizili nophethiloli, umthamo wokuguquguquka nokuwohloka kukaphethiloli kufanele ucatshangelwe. Esikhathini esizayo, lapho i-valve isebenza futhi isigaba sikaphethiloli sihlangene, amafutha kufanele afakwe ngesikhathi ukuvimbela ukuguga.

Okweshumi, lapho umjovo wamafutha, ungawushayi indiva umjovo wamafutha wesiqu se-valve. Ingxenye ye-valve shaft inomkhono we-sliding shaft noma ukupakisha, futhi idinga ukugcina ukugcoba, ukuze kuncishiswe ukumelana nokungqubuzana ngesikhathi sokusebenza, uma ingakwazi ukuqinisekisa ukugcotshwa, i-torque yokulawula kagesi ikhulisa izingxenye zokugqoka, umzamo wokushintsha wokulawula ngesandla.

Ishumi nanye, umzimba we-valve webhola omakwe ngemicibisholo, uma kungekho umbhalo wesandla we-FIOW wesiNgisi, ukuze uthole isiqondiso sesihlalo sokuvala, hhayi njengereferensi yokugeleza okumaphakathi, isiqondiso sokuzikhulula kwe-valve. Imvamisa, ama-valve ebhola anezihlalo ezimbili ezivaliwe anendlela embili.

Okweshumi nambili, ukugcinwa kwe-valve, kodwa futhi unake ikhanda likagesi kanye nokudluliselwa kwayo kwezinkinga zamanzi. Imvula engena ikakhulukazi ngenkathi yezimvula. Enye iwukugqwala isakhiwo se-motor noma umkhono we-shaft wokudlulisela, kanti enye iwukuba yiqhwa ebusika. Isizathu sokuthi i-torque yokusebenza kwe-valve kagesi inkulu kakhulu, ukulimaza izingxenye zokudlulisela kuzokwenza ukuthi injini ingalayishi noma igxume yokuvikela i-torque enkulu ayikwazi ukufinyelela ukulawula kukagesi.
