1. Indlela yokuhlanza
I-slag yokushisela, ukugqwala kanye ne-slag epayipini kubangela ukuvaleka noma ukuminyana emgodini, ingxenye eqondisayo kanye nembobo yebhalansi yesembozo sevalvu engezansi, okuholela ekudonsweni nokuklwebheka ebusweni bomgogodla we-valve nendawo yokuqondisa, kanye nokuhlehla endaweni evalayo. Lokhu kuvame ukwenzeka esigabeni sokuqala sokusebenza kwesistimu entsha nangemva kokulungisa kabusha. Leli iphutha elivame kakhulu. Kulesi simo, kuyadingeka ukususa i-slag yokuhlanza, futhi ugaye uma indawo yokubeka uphawu yonakalisiwe; ngesikhathi esifanayo, vula ipulaki engezansi ukuze ushaye i-slag ewela kukhava yevalvu engezansi ukusuka embotsheni yebhalansi, bese ukhipha ipayipi. Ngaphambi kokuqala ukusebenza, i-valve yokulawula izovulwa ngokugcwele futhi i-medium izogeleza isikhathi esithile ngaphambi kokungena ekusebenzeni okujwayelekile.
2. Indlela yokukhuhla yangaphandle
Lapho i-valve evamile isetshenziselwa ukulawula i-medium okulula ukuduma futhi iqukethe izinhlayiya eziqinile, ivamise ukuvinjelwa ku-orifice kanye nomhlahlandlela. Igesi eshaywayo nesitimu kungaxhunywa kupulaki elingezansi lekhava yevalvu engezansi. Uma i-valve ivinjiwe noma ibambekile, vula igesi yangaphandle noma i-valve yesitimu ukuze uqedele umsebenzi wokuguquguquka ngaphandle kokunyakazisa i-valve yokulawula, ukuze i-valve isebenze ngokujwayelekile.
3. Ukufakwa kwesihlungi sepayipi
Ku-valve yokulawula i-caliber encane, ikakhulukazi i-valve encane yokulawula ukugeleza, imvume yayo ye-throttle incane kakhulu, futhi akufanele kube ne-slag phakathi nendawo. Uma kwenzeka ukuvinjelwa, kungcono ukufaka isihlungi epayipini ngaphambi kwe-valve ukuqinisekisa ukudlula okushelelayo kokuphakathi. Kuvalvu yokulawula ene-positioner, okokumisa akusebenzi ngokujwayelekile, futhi iphutha elivame kakhulu ukuvinjwa kwembobo ye-throttle. Ngakho-ke, lapho usebenza ne-positioner, umthombo womoya kufanele uphathwe kahle. Indlela evamile ukufaka ivalvu yokunciphisa ingcindezi yokuhlunga umoya epayipini lomthombo womoya phambi kwesimo
4. Khulisa i-throttle clearance
Isibonelo, izinhlayiya eziqinile phakathi nendawo noma i-slag yokushisela kanye nokugqwala okugezwe epayipini akukwazi ukudlula i-orifice edonsayo futhi kubangele ukuvinjelwa, ukugxumela kanye namanye amaphutha. Izingxenye ezinyakazayo ezine-throttling clearance enkulu, njenge-valve core kanye nomkhono onefasitela ne-open throttling area, zingasetshenziswa esikhundleni salokho. Ngenxa yokuthi indawo ye-throttling igxilile kunokuba i-circumferentially distributed, iphutha lingaqedwa kalula. Uma kuyi-valve yesihlalo esisodwa noma i-valve yezihlalo ezimbili, umgogodla wevalve omise okwe-plunger ungashintshwa ube umgogodla omise okwe-V noma ivalvu yomkhono. Isibonelo, i-valve yesihlalo esiphindwe kabili esitshalweni samakhemikhali ivame ukunamathela, ngakho-ke kunconywa ukusebenzisa i-valve ye-sleeve, futhi inkinga ixazululwa ngokushesha.
5. Indlela yokukhuhla emaphakathi
Ngokusebenzisa amandla okukhuhla emaphakathi ngokwawo, ingakwazi ukukhuhla futhi isuse izinto okulula ukunamisa futhi ivimbe, ukuze kuthuthukiswe umsebenzi wokuvimba wokuvimba wevalvu. Izindlela ezijwayelekile zimi kanje: ① ukushintsha ukugeleza kohlobo oluvaliwe; ② sebenzisa umzimba we-valve oqondile; ③ beka i-throttle orifice endaweni enzima kakhulu, futhi unake ukuthuthukisa ukumelana nokuguguleka kwe-throttle material.
6. Indlela eqondile iguqulwa ibe yi-angular
Ukugeleza okuqondile kungukugeleza okuhlanekezelwe, indlela yokugeleza iyinkimbinkimbi, futhi kunezindawo eziningi ezifile endaweni engaphezulu nengaphansi, okunikeza indawo yemvula emaphakathi. Uxhumano lwe-angular, okuphakathi kungathi kugeleza ku-90 ℃ indololwane, ukusebenza kahle kokukhuhla, indawo encane efile, kulula ukuyiklama ibe umugqa wokugeleza. Ngakho-ke, lapho i-valve yokulawula eqondile ivinjwe kancane, ingashintshwa ibe yi-engeli valve.
