Ama-valve esangoama-valve anqanyuliwe, ngokuvamile afakwa emapayipini anobubanzi obungaphezu kuka-100mm, ukuze anqamule noma axhume ukugeleza kokuphakathi epayipini.Ngenxa yokuthi i-disc iwuhlobo lwesango, ngokuvamile ibizwa ngokuthi ai-valve yesango.Ii-valve yesangoinezinzuzo zomzamo ophansi wokushintsha kanye nokumelana nokugeleza okuphansi.Kodwa-ke, indawo yokubeka uphawu kulula ukuyigqoka futhi ivuze, i-stroke yokuvula inkulu, futhi ukugcinwa kunzima.Ii-valve yesangoayikwazi ukusetshenziswa njengevalvu elawulayo futhi kufanele ibe sendaweni evuleke ngokugcwele noma evalwe ngokugcwele.Isimiso sokusebenza sithi: lapho i-i-valve yesangoivaliwe, isiqu se-valve siya phansi kuye ngokuthi indawo yokubeka uphawui-valve yesangofuthi indawo yokuvala yesihlalo se-valve ibe bushelelezi kakhulu, isicaba futhi ingaguquki.Ayalingana ukuze avimbele okuphakathi ukuthi angagelezi, futhi athembele ku-wedge ephezulu ukukhulisa umphumela wokuvala.Ucezu lokuvala luhamba ngendlela eqondile yomugqa ophakathi.Kunezinhlobo eziningi zeama-valve esango, ezingahlukaniswa zibe uhlobo lwe-wedge kanye nohlobo oluhambisanayo ngokwezinhlobo zabo.Uhlobo ngalunye luhlukaniswe ngesango elilodwa kanye nesango eliphindwe kabili.
1.2 Isakhiwo:
Umzimba we-valve we-i-valve yesangoithatha ifomu lokuzivala.Ukuxhumana phakathi kwebhonethi nomzimba we-valve ukusebenzisa ukucindezela okungaphezulu kwe-medium ku-valve ukuphoqa ukupakishwa kokuvala ukuthi kucindezelwe ukuze kuzuzwe inhloso yokuvala.Ii-valve yesangoukupakisha kuvalwe nge-asbestos enengcindezi ephezulu epakishwa ngocingo lwethusi.
Isakhiwo se-i-valve yesangoikakhulukazi yakhiwe umzimba we-valve, isembozo se-valve, ifreyimu, isiqu se-valve, ama-discs e-valve yesokunxele nesokudla, kanye nedivayisi yokupakisha uphawu.
2. Inqubo yokulungisa kabushai-valve yesango
2.1 Ukuhlukaniswa kwe-valve:
2.1.1 Khipha amabhawodi okulungisa ohlaka olungaphezulu lwebhonethi, khumula amantongomane amabhawodi amane kubhonethi, phendula isiqu senati ngokuphambene newashi ukuze uhlukanise uhlaka lwe-valve emzimbeni, bese usebenzisa ithuluzi lokuphakamisa ukuphakamisa isivalo. ifreyimu phansi, Yibeke endaweni efanele.I-stem nut kufanele ihlakazwe ukuze ihlolwe.
2.1.2 Khipha iringi eyibamba eringini eyisikwele kane yomzimba wevalvu, bese ucindezela phansi ibhonethi ngethuluzi elikhethekile ukwenza igebe phakathi kwebhonethi neringi kane.Bese ukhipha iringi yesine ngezigaba.Okokugcina, sebenzisa ithuluzi lokuphakamisa ukuphakamisa isembozo se-valve kanye nesiqu se-valve kanye nokuphuma kwe-valve emzimbeni we-valve.Yibeke endaweni yokulungisa, futhi unake ukuvimbela ukulimala endaweni ehlangene ye-valve clack.
2.1.3 Hlanza ingaphakathi lomzimba wevalvu, hlola indawo ehlangene yesihlalo sevalvu, bese unquma indlela yokuyinakekela.Vala i-valve ehlakaziwe ngepuleti lekhava elikhethekile noma ikhava, bese unamathisela uphawu.
2.1.4 Thuthukisa amahinge amabhawodi ebhokisi lokugxusha kukhava yevalvu.Indlala yokupakisha iyaxegiswa futhi isiqu se-valve asikulungi.
2.1.5 Khipha ama-splints aphezulu naphansi wefreyimu yediski, khipha amadiski angakwesokunxele nakwesokudla, bese ugcine i-universal top yangaphakathi kanye ne-gasket.Linganisa ubukhulu be-gasket bese wenza irekhodi.
2.2 Ukulungiswa kwezingxenye ezahlukene zevalvu:
2.2.1 Indawo ehlangene ye-i-valve yesangoisihlalo kufanele sigaywe ngethuluzi elikhethekile lokugaya (isibhamu sokugaya, njll.).Ukugaya kungasebenzisa isihlabathi esiqhumayo noma indwangu ye-emery.Indlela ibuye isuke kokumahhadla iye kwehle, futhi ekugcineni ipholishwe.
2.2.2 Indawo ehlangene ye-valve clack ingagaywa ngesandla noma ngomshini wokugaya.Uma indawo engaphezulu inomgodi ojulile noma umsele, ingathunyelwa ku-lathe noma umshini wokugaya ukuze icutshungulwe kancane, futhi izopholishwa ngemva kwakho konke izinga.
2.2.3 Hlanza ibhonethi kanye nokupakishwa kokuvala, susa ukugqwala nokungcola ezindongeni zangaphakathi nezingaphandle zeringi yokupakisha, ukuze indandatho yokucindezela ifakwe kahle engxenyeni engenhla yebhonethi, futhi kube lula cindezela ukupakisha uphawu.
2.2.4 Hlanza ukupakishwa kwangaphakathi kwebhokisi le-valve stem, hlola ukuthi indandatho yangaphakathi yokupakisha ilungile yini, igebe phakathi kwembobo yangaphakathi nenduku yokusika kufanele ihlangabezane nezidingo, neringi yangaphandle kanye nodonga lwangaphakathi lokugxusha. ibhokisi akufanele liboshwe.
2.2.5 Hlanza ukugqwala ku-packing gland kanye ne-pressure plate, futhi ingaphezulu kufanele lihlanzeke futhi liphelele.Igebe phakathi kwembobo yangaphakathi yegland kanye nenduku yokusika kufanele ihlangabezane nezidingo, futhi udonga lwangaphandle kanye nebhokisi lokugxusha kufanele likhululeke kuma-jams, ngaphandle kwalokho ukulungiswa kufanele kwenziwe.
2.2.6 Thuthukisa amahinge amabhawodi, hlola ukuthi ingxenye enentambo ayilungile yini nokuthi inathi liqinile, lingakrunwa kancane impande yebhawodi ngesandla, futhi iphinikhodi kufanele libe flexible ukuze lizungeze.
2.2.7 Hlanza ukugqwala ebusweni besiqu se-valve, hlola ukugoba, futhi uqondise uma kunesidingo.Ingxenye yentambo ye-trapezoidal kufanele iphelele, ngaphandle kokuphuka nokulimala, futhi iboshwe nge-powder ehola ngemva kokuhlanza.
2.2.8 Hlanza iringi yesine, futhi ingaphezulu kufanele libe bushelelezi.Indiza akufanele ibe nama-burrs noma imiphetho egoqekayo.
2.2.9 Wonke amabhawodi okubopha kufanele ahlanzwe, amantongomane kufanele aphelele futhi aguquguquke, futhi izingxenye ezinentambo kufanele zimbozwe ngempushana eholayo.
2.2.10 Hlanza i-stem nut ne-internal bearing:
①Susa i-valve stem nut lock kanye nesikulufu sokulungisa sendlu, bese ukhulula isikulufu sokukhiya ngendlela ephambene newashi.
② Khipha i-stem nut ne-bearing, i-disc spring, bese uyihlanze ngophalafini.Hlola ukuthi ingabe i-bearing ijikeleza ngendlela eguquguqukayo kanye nokuthi isiphethu sediski sinokuqhekeka yini.
③ Hlanza i-valve stem nut, hlola ukuthi isikulufu sangaphakathi se-trapezoidal siqinile, futhi isikulufu sokulungisa esinegobolondo kufanele siqine futhi sithembeke.Ukugqoka kwe-bushing kufanele kuhlangabezane nezidingo, ngaphandle kwalokho kufanele kushintshwe.
④ Gcoba ibhere ngebhotela bese ulifaka ku-stem nut.Ama-disc springs ahlanganiswa njengoba kudingekile futhi aphinde ahlanganiswe ngokulandelana.Ekugcineni, ikhiye ngenati lokukhiya, bese uyilungisa ngokuqinile ngesikulufu.
2.3 Umhlangano wei-valve yesango:
2.3.1 Faka ama-disc afanelekile kwesokunxele nakwesokudla eringini ye-stem clamp bese uwalungisa ngezinsimbi ezingenhla nezingezansi.Ingaphakathi layo kufanele lifakwe phezulu kwendawo yonke, futhi i-gasket yokulungisa kufanele ihlolwe ngokuvumelana nesimo sokugcinwa.
2.3.2 Faka isiqu se-valve kanye nediski ye-valve esihlalweni sevalvu ukuze sihlolwe.Ngemuva kokuthi i-disc ye-valve kanye nendawo yokuvala yesihlalo se-valve kuxhumene ngokugcwele, kufanele kuqinisekiswe ukuthi indawo yokuvala ye-valve disc iphakeme kunendawo yokuvala yesihlalo se-valve futhi ihlangabezana nezidingo zekhwalithi.Uma kungenjalo, kufanele ilungiswe.Ubukhulu be-gasket phezulu kuze kube yilapho kufanelekile, futhi i-anti-return gasket isetshenziselwa ukuyibeka ukuze ivimbele ukuthi ingawi.
2.3.3 Hlanza umzimba wevalvu, bese usula isihlalo sevalvu nediski.Bese ufaka isiqu se-valve kanye nediski ye-valve esihlalweni, bese ufaka isembozo se-valve.
2.3.4 Faka ukupakisha okuvala njengoba kudingekile engxenyeni yebhonethi yokuzivala.Ukucaciswa kokupakisha kanye nenani lokujika kufanele kuhlangabezane nezinga lekhwalithi.Ingxenye engenhla yokupakisha icindezelwa ngokuqinile ngendandatho yokucindezela, futhi ekugcineni ivalwe nge-cover plate.
2.3.5 Hlanganisa iringi kane ngezigaba ngayinye ngayinye, sebenzisa iringi yokuyibamba ukuze uyinwebe ukuze uyivimbele ukuthi ingawi, futhi uqinise inadi lebhawodi eliphakamisa ibhonethi.
2.3.6 Gcwalisa ibhokisi lokugxilisa isiqu se-valve ngokupakisha njengoba kudingekile, ulifake endlaleni yokusebenza kanye nepuleti lokucindezela, bese ulibheka uliqinise ngesikulufu sehinge.
2.3.7 Faka ifremu yebhonethi, zungezisa i-stem nut ukuze wenze ifremu iwele emzimbeni wevalvu, futhi uyibophe ngamabhawudi axhumayo ukuze ingawi.
2.3.8 Faka idivayisi yokushayela i-valve kagesi;ucingo olungaphezulu lwengxenye yokuxhuma kufanele luqiniswe ukuze lungawi, futhi uhlole mathupha ukuthi i-flap switch iyavumelana nezimo yini.
2.3.9 I-nameplate yevalvu icacile, ilungile futhi ilungile.Amarekhodi okunakekela aphelele futhi acacile;futhi ulwazi lwamukelwe njengokufanelekile.
2.3.10 Amapayipi namavalvu anokufakwa okuphelele, futhi indawo yokulungisa kufanele ihlanzwe.
