(14) indawo yokukhenkceza ephantsi yeliphakathi iyafana nokukhethwa ngokubanzi kwebhatyi yobushushu yohlobo lwevalve yokhuseleko.
Ukulungelelaniswa kwevalvu yokhuseleko kunye nokugcinwa
Ukuvavanya izalathisi zokusebenza kobugcisa bevalve yokhuseleko kufuneka ibe luvavanyo olupheleleyo lokusebenza, uvavanyo eyona mfuno isisiseko kukuba neyona meko isebenzayo, nangaphezulu kunemeko yokwenyani yokuqhuba. Ukongeza kubushushu obuphezulu kunye neenqanawa zoxinzelelo oluphezulu kunye nezinye izixhobo, esi sixhobo sovavanyo kufuneka sixhotyiswe ngeendlela ezahlukeneyo zokuzimisela ngokukhawuleza kweeparamitha, kwaye siqinisekise ukuhamba okukhulu kobushushu obuphezulu kunye nomthombo woxinzelelo oluphezulu, ixabiso likhulu.
Ukutshekisha yinxalenye yovavanyo lwevalvu yokhuseleko kwaye yeyona nto iphambili yovavanyo lwasefektri. Ngaphambi kokuba ushiye umzi-mveliso, itafile yokukhangela ivalve yokhuseleko kwindawo yobushushu begumbi isetyenziselwa ukuvula uhlengahlengiso loxinzelelo kunye novavanyo lokutywina lomoya ophakathi. Itheyibhile yokukhangela ubushushu begumbi lokhuseleko inokwenza kuphela uhlengahlengiso oluvulekileyo loxinzelelo kunye novavanyo lokutywina.
(1) Kuphantsi kwaziphi iimeko apho isivalo sokhuseleko kufuneka sijongwe
1) Ngaphambi kokugcinwa kwexesha elide okanye * sebenzisa
2) Ukuqinisekiswa rhoqo
3) Iivalve ezonakalisiweyo kakhulu kunye ne-corrod
4) Iivalvu ezineepleyiti zevalvu ezingekhoyo
I-5) I-Valve enetywina elikhokelayo elonakeleyo
(2) Ukubaluleka kunye nendlela yokulungelelanisa uxinzelelo lwesihlalo
Umgangatho wesizwe wenkcazo yoxinzelelo lwangasemva ubhekiselele kwivalvu yokukhulula ukukhupha, uxinzelelo oluphakathi lwehla ukuya kwixabiso elithile, idiski yokunxibelelana nesihlalo, oko kukuthi ukuphakama okuvulekileyo ngu-zero, indawo yokungena yevalve yoxinzelelo olumileyo, uxinzelelo lwangasemva lukhulu kakhulu. iphantsi, ininzi kakhulu imbi, iphantsi kakhulu iya kubangela ukulahleka okuphakathi kunye namandla, iphezulu kakhulu, imfutshane yokukhutshwa, ibangele i-valve frequency jump, Umgaqo kukulungelelanisa uxinzelelo lwesihlalo sangasemva kangangoko kunokwenzeka ukunciphisa ilahleko ephakathi kunye amandla kwimeko yokuphumeza izinto ezikhutshwayo.
(3) Indlela yokulungelelanisa
Uxinzelelo lwesihlalo sangasemva luhlengahlengiswa ngokulungelelanisa i-ring, umgaqo wohlengahlengiso ngumgaqo we-gap, i-gap encinci, inkulu ukuchasana xa ukhupha, amandla amakhulu abambe i-spool phantsi, kunzima kakhulu ukubuyela kwi-spool. isihlalo, ngokuchaseneyo, i-gap inkulu, kulula ngakumbi ukuba i-spool ibuyele umva, iphakamileyo yoxinzelelo lwesitulo sangasemva.
Kwivalve yokhuseleko eneringi yokulawula esezantsi kuphela, isandi esilawulayo siphezulu, uxinzelelo lwesihlalo sangasemva luphantsi, iringi yokulawula iphantsi, uxinzelelo lwesihlalo sangasemva luphezulu; Kwivalve yokhuseleko eneringi yokulawula phezulu nasezantsi, umgama weringi yokulawula phezulu nasezantsi uyehla, uxinzelelo lwesihlalo sangasemva luyehla, umgama wokunyuka nokuhla wokulawula umsesane uyenyuka, uxinzelelo lwesihlalo sangasemva luyanda.
(4) khangela indlela kunye neengenelo kunye nokungalunganga
Ukukhangela i-valve yokukhusela ine-check field (ukukhangela i-intanethi) kwaye ukhangele itafile jonga iindlela ezimbini, iimeko ezivumelayo kufuneka zizame ukukhangela kwintsimi, kuba ukukhangela intsimi kukulungele ngakumbi iimeko zokusebenza zangempela, ngoko kunokuba ngcono.
Iinzuzo zokujonga intsimi: kulula ukujonga i-valve yokukhusela i-welding, inokulinganiswa uxinzelelo lwangasemva, umlinganiselo ochanekileyo.
Ukungalungi kukuba ixesha lokulinganisa lide, inkqubo kufuneka iphakanyiswe ngokuphindaphindiweyo, kungekhona uqoqosho, ingozi ngakumbi, ayikwazi ukwenza uvavanyo lokutywinwa.
Izinto eziluncedo kunye nezingeloncedo kwitafile yokukhangela ubushushu begumbi levalve yokhuseleko:
A. Sombulula uhlengahlengiso kunye nokufumanisa ukuvuza kwevalve yokhuseleko lobushushu obuqhelekileyo obuphakathi kunye nobushushu bokusebenza obungaphantsi kwe-250C.
B. Ukugqiba uluhlu oluncinci lwephutha loxinzelelo lokuvula i-valve yokukhusela, gcina ixesha lokulungelelanisa i-valve yokhuseleko esanda kufakwa, ukunciphisa amandla okusebenza, ukunciphisa ukusetyenziswa kwamandla kunye nokunciphisa umngcipheko womsebenzi.
C. Kukho impazamo phakathi kweqondo lokushisa elisebenzayo kunye nobushushu obuqhelekileyo (intwasahlobo iba yithambile kwiqondo lokushisa eliphezulu), kwaye uxinzelelo lwesihlalo sangasemva alukwazi ukuqinisekiswa.
(5) isixhobo esisetyenziselwa ukuqinisekiswa kobushushu obuqhelekileyo
Umoya, initrogen kunye namanzi zisetyenziswa ngokubanzi ukuqinisekisa ubushushu obuqhelekileyo (uxinzelelo lungaphezulu kwe-20Mpa). Ioksijini, i-hydrogen, igesi yeacetylene kunye nezinye izinto ezinokutsha, ezixhasa ukutsha okanye eziyingozi neziyingozi azinakusetyenziswa njengobungqina bomthombo ophakathi. I-kerosene, i-petroli, i-diesel, njl., ayinakusetyenziswa njengomthombo ophakathi. Nangona igesi ye-carbon dioxide ayinayo ityhefu kwaye ayinakutsha, kulula ukukhenkceza kunye nokuvala umbhobho.
(6) umgaqo wokulinganisa ivalve yokhuseleko
I-medium enoxinzelelo igqithiselwa kwi-inlet yevalve ekhuselekileyo yokhuseleko. Xa uxinzelelo oluphakathi luphakama kwindawo evulekileyo yevalve yokhuseleko, uxinzelelo ngeli xesha lulinganiswa, kwaye uxinzelelo lokuvula lubekwe kwaye luhlengahlengiswe kwixabiso elichaziweyo lokuvula ukugqiba ukuqinisekiswa koxinzelelo lokuvula. Emva koko xa uxinzelelo lwehla kwixabiso elichaziweyo (i-90% yoxinzelelo lokuvula), i-gauge yoxinzelelo okanye ezinye iindlela zomthetho zisetyenziselwa ukujonga ukuvuza okuphakathi, oko kukuthi, ukutywinwa kokutywinwa.
Uyiqinisekisa njani ivalve yokhuseleko lokulinga ngokuchanekileyo nangokukhawuleza
Ivalve yokhuseleko lokulinga luhlobo lwevalve yokhuseleko enesakhiwo senoveli. Isetyenziswa kakhulu kwi-petroleum kunye negesi ye-NATURAL, ishishini lemichiza, amandla ombane, isinyithi kunye negesi yesixeko kunye nezinye iindawo. Sesona sixhobo sokukhusela ucinezelo kwisixhobo esicinezelekileyo, izikhongozeli okanye imibhobho. Inzuzo yayo ephambili kukuba inyathelo elithe ngqo lentwasahlobo yesiphumo somqhubi ongathanga ngqo, siphucula ubuntununtunu besenzo, kwaye umkhono usetyenziswa kwipiston yevalve ephambili, isihlalo sokutywinwa kabini, ukuchaneka okuphezulu, ukuphindaphindwa okuhle, umva ukuhamba ngokukhawuleza, awukwazi ukuvuza. , thatha ukukhutshwa koxinzelelo oluphezulu, ubomi obude bokusebenza, umsebenzi ozinzileyo kwaye unokwethenjelwa, unokuba nokulungelelaniswa kwe-intanethi, kwaye utsibe kwakhona kwaye emva kokukhutshwa, unokubuyela ngokuzenzekelayo, Vala ngokuqinileyo, kulula ukuyisebenzisa kunye nokugcina.
Ivalve yokhuseleko yohlobo lokulinga
Ivalve yokhuseleko olulingwayo isekelwe kwisiseko sevalve yokhuseleko eqhelekileyo yasentwasahlobo, yongeza indlela yokulinga, ukuze isivalo sokhuseleko sibe nevalve yokhuseleko olulingwayo kunye nendima ephindwe kabini yesivalo esiqhelekileyo sokhuseleko. Iimpawu zayo zezi: isenzo esichanekileyo nesithembekileyo; Ukusebenza kokutywina kuphuculwe kakhulu; Umahluko wokuvula kunye nokuvala uxinzelelo kulula ukuhlangabezana neemfuno; Isenzo esinovakalelo, izinto ezikhutshwayo ezinkulu. Ngaba uyazi ukuba ivalve yokhuseleko lokulinga kufuneka ilinganiswe njani? Ingcali yethu yevalvu yakwaLeco iya kukulungiselela olu lwazi.
Ivalve yokhuseleko lohlobo lwasentwasahlobo
Uvavanyo lwenkqubo yokuqinisekisa ivalve yokhuseleko:
Okokuqala, ukukhangela i-valve ye-pilot yokhuseleko ngokuqhelekileyo kuthunyelwe kwi-check station isheke ngumsebenzisi, kwiimeko ezikhethekileyo zingasetyenziselwa ukukhangela kwintsimi, umsebenzisi wokukhangela indawo kufuneka abonelele ngeemeko eziyimfuneko zokujonga.
Okwesibini, umsebenzisi kufuneka abonelele ngeenkcukacha zomzi-mveliso wevalufa yokulinga yokhuseleko, uxinzelelo loyilo kunye noxinzelelo lokusebenzisa lombhobho wesixhobo, ingxelo yokugqibela yolungelelwaniso okanye uluvo lolungelelwaniso olukhutshwe ngumhloli wesixhobo.
Okwesithathu, jonga idatha ethunyelwe ukuba iphononongwe, misela uxinzelelo lokumisela.
4. Qwalasela isivalo sokhuseleko esilingwayo esandula kufakwa ngedatha epheleleyo. Kwiimeko eziqhelekileyo, iintsuku ezimbini zokusebenza zinqweneleka; Kwivalve yokhuseleko lokulinga ngobuninzi okanye idinga ukulungiswa, ixesha lokugqiba liya kumiselwa ngokweyona meko ngokubonisana nomsebenzisi.
Ezintlanu, ngokomxholo wokulinganisa, gcwalisa irekhodi yokulinganisa, ukhuphe ingxelo yokuhlola.
Isithandathu, emva kokuqinisekiswa, umvavanyi uya kwazisa umsebenzisi ukuba afumane ivalve yokhuseleko lomqhubi kunye nengxelo yokuhlola.
