Izindlela zokuhlanganisa i-valve ezivame ukusetshenziswa
Izindlela zokuhlanganisa i-valve ezivame ukusetshenziswa zingaba nezinhlobo ezintathu, okungukuthi indlela ephelele yokufaka esikhundleni, indlela yokulungisa nendlela yokufanisa:
(1) indlela yokushintshanisa ephelele: lapho i-valve ihlanganiswa ngendlela ephelele yokushintshanisa, ingxenye ngayinye ye-valve ingaqoqwa ngaphandle kokugqoka nokuzikhethela, futhi umkhiqizo ungahlangabezana nezidingo zobuchwepheshe ezicacisiwe ngemva kokuhlanganiswa. Ngalesi sikhathi, izingxenye ze-valve kufanele zicutshungulwe ngokuphelele ngokuhambisana nezidingo zokuklama ukuze zanelise ukunemba kwe-dimensional ngesimo nesicelo sokubekezelela isikhundla. Izinzuzo zendlela yokushintshanisa ephelele yilezi: umsebenzi womhlangano ulula, umnotho, abasebenzi abadingi izinga eliphezulu lekhono, ukusebenza kahle kokukhiqizwa kwenqubo yomhlangano kuphezulu, kulula ukuhlela umugqa womhlangano kanye nenhlangano yokukhiqiza okukhethekile. Kodwa-ke, lapho ukuhlanganiswa okuphelele kokushintshwa kwamukelwa, ukunemba komshini wezingxenye kuyadingeka ukuthi kube phezulu. Ifakwe ku-valve yeglobhu, i-valve yokuhlola, i-valve yebhola nokunye ukwakheka okulula kwesigaba se-valve kanye ne-diameter encane.
(2) Indlela yokufanisa: i-valve ithatha indlela yokuhlanganisa yokuhlanganisa, wonke umshini ungacutshungulwa ngokuvumelana nokunemba kwezomnotho, bese ukhetha usayizi onomphumela wokulungisa kanye nesinxephezelo ngesikhathi somhlangano, ukuze ufinyelele ukunemba komhlangano ocacisiwe. Isimiso sendlela yokufanisa siyafana nendlela yokulungisa, indlela kuphela yokushintsha ubukhulu bendandatho yesinxephezelo ihlukile. Owokuqala uwukushintsha usayizi wendandatho yesinxephezelo ngokukhetha izesekeli, kanti okokugcina kuwukushintsha usayizi wendandatho yesinxephezelo ngokugqoka izesekeli. Isibonelo, umgogodla ophezulu kanye ne-gasket yokulungisa ye-valve yesango le-wedge ephindwe kabili yemodeli ye-valve yokulawula, kanye ne-gasket yokulungisa phakathi kwemizimba emibili ye-valve yebhola evulekile kukhethwa njengezingxenye zesinxephezelo kuchungechunge lwe-dimension oluhlobene nokunemba komhlangano, futhi ukunemba komhlangano odingekayo kufinyelelwa ngokulungisa ubukhulu nobukhulu be-gasket. Ukuze kuqinisekiswe ukuthi izingxenye zesinxephezelo esingaguquki zingakhethwa ngaphansi kwezimo ezihlukene, kuyadingeka ukwenza isethi yamamodeli e-hydraulic control valve of gasket kanye nezingxenye zesinxephezelo semikhono ezinosayizi abahlukene bokujiya kusengaphambili ukuze kukhethwe ekuhlanganisweni.
(3) Indlela yokulungisa: i-valve ihlanganiswa ngendlela yokulungisa. Izingxenye zingacutshungulwa ngokuya ngokunemba kwezomnotho. Ngesikhathi sokuhlanganiswa, usayizi wokulungiswa okuthile kanye nomphumela wesinxephezelo ungalungiswa ukuze kuzuzwe umgomo oshiwo womhlangano. Isibonelo, isango le-valve yesango le-wedge kanye nomzimba we-valve, ngoba izindleko zokucubungula izidingo zokushintshana ziphezulu kakhulu, abakhiqizi abaningi basebenzisa ubuchwepheshe bendlela yokulungisa. Okungukuthi, lapho ulawula usayizi wokuvula wesango lokuvala ubuso ekugayweni kwangemuva, ipuleti kufanele lifaniswe ngokuvumelana nobukhulu bokuvula bomzimba we-valve wokuvala ubuso ukuze kuzuzwe izidingo zokuvala. Le ndlela yengezwa kwinqubo yepuleti, kodwa ** yenza lula izidingo zokunemba kobukhulu benqubo yokucubungula yangaphambili, inqubo yepuleti yomuntu onekhono lokusebenza, ngokuvamile ngeke kuthinte ukusebenza kokukhiqiza. Inqubo yokuhlanganisa i-valve: I-valve ihlanganiswa ngayinye endaweni engashintshi. Ukuhlanganiswa kwezingxenye kanye nezingxenye ze-valve kwenziwa ku-workshop yomhlangano, futhi zonke izingxenye ezidingekayo kanye nezingxenye zihanjiswa endaweni yokusebenza yomhlangano. Ngokuvamile izingxenye zomhlangano kanye nokuhlanganiswa okuphelele zihlukanisa ngokuthi mangaki amaqembu ezisebenzi ngesikhathi esisodwa, angafinyezi nje kuphela umjikelezo womhlangano, kodwa futhi enze kube lula ukusetshenziswa kwamathuluzi omhlangano angcono kakhulu, izidingo zezinga lobuchwepheshe labasebenzi nazo ziphansi kakhulu.
Abanye abakhiqizi bakwamanye amazwe noma ama-valve ebanga lobuchwepheshe obuphezulu nawo anokusetshenziswa komugqa wokumisa umhlangano noma imodi yetafula elijikelezayo lomhlangano:
(1) Umsebenzi wokulungiselela ngaphambi kokuhlanganiswa: Izingxenye zevalvu zizosusa i-burr eyenziwe ngomshini wokucubungula kanye nezinsalela zokushisela, zihlanze futhi zisike ukupakisha kanye ne-gasket ngaphambi kokuhlanganisa.
(2) ukuhlanza izingxenye zevalvu: njengokufakwa kokulawula ipayipi eliwuketshezi levalvu, imbobo yangaphakathi kufanele ihlanzeke. Ikakhulukazi amandla enuzi, imithi, ama-valve embonini yokudla, ukuze kuqinisekiswe ukuhlanzeka kwe-medium nokugwema ukutheleleka okuphakathi, izidingo zokuhlanzeka kwe-valve cavity zinzima kakhulu. Hlanza IINGXENYE ZE-VALVE NGAPHAMBI KOMHLANGANO UKUZE UKUSELE IZIBANDAKAZI, AMAFUTHA ESALE BUSHELELA, I-COOLANT KANYE NE-BURR, I-SLAG YOKUSHIYA KANYE OKUNYE Ukungcola Ezingxenyeni. Ukuhlanzwa kwe-valve KUVAMILE NGOKUFUTHELA AMANZI noma AMANZI ASHISAYO nge-ALKALI (KEROSENE INGASE ISENZISWE Ukuhlanza) noma kusihlanzi se-ultrasonic. Izingxenye zidinga ukuhlanzwa ngemva kokugaya nokupholishwa, futhi ukuhlanzwa kuvame ukuxubha indawo yokuvala ngophethiloli, bese yomile ngomoya ocindezelwe bese usula ngendwangu.
(3) ukupakisha kanye nokulungiswa kwe-gasket: ukupakisha kwe-graphite kusetshenziswe kabanzi ngenxa yezinzuzo zokumelana nokugqwala, ukubekwa uphawu okuhle kanye ne-coefficient encane yokungqubuzana. I-filler ne-gasket ukuvimbela ukuvuza kwemidiya ngesiqu nesembozo kanye nobuso obuhlangene be-flange. Lokhu kufakwa kufanele kulungiselelwe ukusika nokuphathwa ngaphambi kokuhlanganiswa kwe-valve.
(4) Ukuhlanganiswa kwe-valve: i-valve ngokuvamile isekelwe emzimbeni we-valve njengezingxenye zereferensi ngokuvumelana nokuhlelwa kanye nendlela echazwe inqubo yokuhlanganisa. Ngaphambi kokuhlanganisa, izingxenye nezingxenye kufanele zibuyekezwe ukuze kugwenywe izingxenye ezingashisiwe nezingcolile zingangeni emhlanganweni wokugcina. Ngesikhathi sokuhlanganisa, izingxenye kufanele ziphathwe ngokucophelela ukugwema ukungqongqoza nokuklwebha abasebenzi abalungisayo. Izingxenye ezisebenzayo ze-valve (njenge-valve stem, i-bearing, njll.) kufanele ziboshwe ngebhotela lezimboni. I-flange yesembozo se-valve kanye nomzimba we-valve uxhunywe ngama-bolts. Lapho ama-bolts e-fastening, impendulo kuthiwa, ihlanganiswe, ngokuphindaphindiwe futhi iqiniswe ngokulinganayo. Uma kungenjalo, ingaphezulu elihlangene lomzimba we-valve kanye nesembozo se-valve kuzoveza ukuvuza kwe-valve yokulawula ukugeleza ngenxa yamandla angalingani azungezile. Isibambo esisetshenziselwa ukubopha akufanele sibe side kakhulu ukuvimbela ukulayisha kuqala ukuthikamezi amandla ebhawodi. Kuma-VALVESI ANEzidingo ezinzima ze-PRELOAD, izibambo ze-torque zizosetshenziswa ukuze kuqiniswe amabhawodi ngokuya ngezidingo zetorque ezishiwo. Ngemuva kokuhlanganiswa, indlela yokulawula kufanele ijikelezwe ukuze kubhekwe ukuthi umsebenzi wezingxenye zokuvula nokuvala ivalvu uyahamba yini nokuthi sikhona yini indawo yokuvinjwa. Isembozo se-VALVE, ukusekelwa kanye nezinye izingxenye zesiqondiso sedivayisi ngokuhambisana nezidingo zemidwebo, konke ukubuyekezwa kudlule i-valve ingahlolwa.

Imodi yokuxhuma ye-actuator kagesi kanye ne-valve I-actuator kagesi ihambisana kakhulu ne-valve, esetshenziswa ohlelweni lokulawula okuzenzakalelayo. Kunezinhlobo eziningi zama-actuator kagesi, ahlukile kumodi yesenzo. Isibonelo, i-angular stroke actuator iyitorque engu-angular ephumayo, kuyilapho i-angular stroke actuator iwumphumela wokukhipha indawo. Uhlobo lwe-actuator kagesi ohlelweni lokusebenza kufanele lukhethwe ngokuya ngezidingo zomsebenzi we-valve.

Indlela yokuxhumana
I. Ukuxhumeka kwe-Flange:
Lona uhlobo oluvame kakhulu lokuxhuma kwe-valve. Ngokusho kokuma kwendawo ehlangene, ingahlukaniswa ngokulandelayo:
1. Uhlobo olubushelelezi: lusetshenziselwa ama-valve anengcindezi ephansi. Ukucubungula okulula
2, uhlobo lwe-concave kanye ne-convex: ingcindezi ephezulu yokusebenza, ingasetshenziswa ku-washer eqinile
3. Uhlobo lwe-Tenon ne-groove: i-gasket ene-deformation yepulasitiki enkulu ingasetshenziswa kumidiya egqwalayo, futhi umphumela wokuvala ungcono.
I-4, i-trapezoidal groove: sebenzisa indandatho yensimbi eyi-oval njengewasha, esetshenziselwa ingcindezi yokusebenza ≥64 kg/cm2 valve, noma i-valve yokushisa ephezulu.
I-5, uhlobo lwe-lens: i-washer iyisimo se-lens, esenziwe ngensimbi. Kuma-valve anengcindezi ephezulu yokusebenza ≥100 kg/cm2, noma ama-valve okushisa aphezulu.
I-6, uhlobo lwendandatho ye-O: Leli yifomu elisha lokuxhumana le-flange, lakhiwa ngokubukeka kwe-O ring yerabha ehlukahlukene, kumphumela wokuvala wefomu lokuxhuma.
Okwesibili, uxhumano lwentambo:
Lena indlela elula yokuxhuma futhi ivame ukusetshenziswa nama-valve amancane. Kukhona amanye amacala amabili:
1, ukubekwa uphawu okuqondile: imicu yangaphakathi neyangaphandle idlala indima yokubekwa uphawu. Ukuze kuqinisekiswe ukuthi ilunga alivuzi, ngokuvamile namafutha omthofu, i-linoleum kanye ne-PTFE impahla eluhlaza egcwele; Ibhande le-Ptfe impahla eluhlaza, ukusetshenziswa kokuthandwa okwandayo; Le nto inokumelana nokugqwala okuhle, umphumela omuhle wokuvala uphawu, kulula ukuyisebenzisa futhi ulondoloze, i-disassembly, ingasuswa ngokuphelele, ngoba ifilimu engeyona i-viscous, engcono kakhulu kunamafutha okuhola, i-linoleum.
2. Ukubekwa uphawu okungaqondile: amandla okuqinisa isikulufu adluliselwa kumshini wokuwasha phakathi kwezindiza ezimbili, ukuze iwasha idlale indima yokuvala.
Okwesithathu, uxhumano lomkhono wekhadi:
Umgomo wokuxhuma kanye nokuvala umkhono wokubopha ukuthi uma inati liqiniswa, umkhono wokubopha ungaphansi kwengcindezi, ukuze unqenqema lwawo lulume odongeni olungaphandle lwepayipi, futhi umkhono wokubopha umkhono wangaphandle wekhoni useduze nekhoni yomzimba ohlangene. ngaphansi kwengcindezi, ngakho-ke ingavimbela ngokuthembekile ukuvuza.
Izinzuzo zalolu hlobo lokuxhuma yilezi:
1, usayizi omncane, isisindo esilula, isakhiwo esilula, ukuhlakazeka okulula;
2, ukuxhumana okuqinile, ukusetshenziswa okubanzi, kungamelana nengcindezi ephezulu (1000 kg/cm2), izinga lokushisa eliphezulu (650 ℃) nokudlidliza
I-3, ingakhetha izinto ezihlukahlukene, ezifanele ukuvimbela ukugqwala;
I-4, izidingo zokunemba komshini aziphezulu; Kulula ukufaka endaweni ephakeme.
Ifomu lokuxhuma lomkhono wokugoqa lisetshenziswe emikhiqizweni emincane yamavalvu e-diameter e-China.
Okwesine, uxhumano lwe-clamp:
Le INDLELA YOKUXHUMANA OKUSHESHAYO IDINGA AMABHUTI AMABILI KUPHELA FUTHI IYAFANELEKELA AMAVAVAVA OKUCINDEZELELA aphansi akhishwa njalo.
Okwesihlanu, ukuxhumana okuziqinisayo kwangaphakathi:
Ngaphezu kwazo zonke izinhlobo zamafomu okuxhumana, ukusetshenziswa kwamandla angaphandle ukuze kuncishiswe ingcindezi ye-medium, ukufeza ukubekwa uphawu. Okulandelayo kuchaza uhlobo lokuxhumana oluziqinisayo usebenzisa ingcindezi ephakathi. Indandatho yayo yokuvala ifakwe ku-cone yangaphakathi, ohlangothini oluphambene oluphakathi lube yi-Angle ethile, ukucindezela okuphakathi ku-cone yangaphakathi, futhi idluliselwe kwendandatho yokuvala, ku-Angle ethile ye-cone surface, ikhiqize izingxenye ezimbili, enye ifana umugqa omaphakathi womzimba we-valve ngaphandle, enye ingcindezi odongeni lwangaphakathi lomzimba we-valve. Ingxenye yokugcina ingamandla aziqinisayo. Uma umfutho ophakathi umkhulu, amandla aziqinisayo abe mkhulu. Ngakho lolu hlobo lokuxhuma lufanelekile kuma-valve aphezulu. Igcina izinto eziningi kanye nomsebenzi kunokuxhumeka kwe-flanged, kodwa futhi idinga inani elithile lokulayisha kuqala, ukuze ukucindezela ku-valve kungabi okuphezulu, ukusetshenziswa okuthembekile. I-valve eyenziwe ngomgomo wokuzivala ngokuziqinisa ngokuvamile i-valve yokucindezela okukhulu.
Kunezinhlobo eziningi zokuxhuma kwe-valve, isibonelo, abanye akudingeki bakhiphe i-valve encane, ehlanganiswe kanye nepayipi; Amanye ama-valve angewona awensimbi, esebenzisa uxhumano lwesokhethi, njalonjalo. Abasebenzisi bevalvu kufanele belashwe ngokwemibandela ethile.
