Indlela yokusebenzisa i-valve ngokuchanekileyo ifanelekile ukuqokelela!

I-valve sisixhobo esisetyenziselwa ukulawula isalathiso, uxinzelelo kunye nokuhamba kolwelo kwinkqubo yolwelo.Sisixhobo esenza i-medium (ulwelo, igesi, umgubo) uhambe okanye umise kwimibhobho kunye nezixhobo kwaye inokulawula ukuhamba kwayo.I-valve yinto ebalulekileyo yokulawula inkqubo yokuthutha ulwelo.
Ukulungiselela ngaphambi kokusebenza
Funda imiyalelo yokusebenza ngononophelo phambi kokuba usebenze isivalo.Ngaphambi kokusebenza, indlela yokuhamba kwegesi kufuneka icace, kwaye i-valve yokuvula kunye neempawu zokuvala kufuneka zihlolwe.Jonga inkangeleko yevalve ukubona ukuba ifumile na.Ukuba ifumile, kufuneka yomiswe;ukuba kukho nayiphi na enye ingxaki, kufuneka iphathwe kwangexesha, kwaye akukho msebenzi wempazamo uvunyelweyo.Ukuba i-valve yombane imisiwe ngaphezu kweenyanga ezi-3, i-clutch kufuneka ihlolwe ngaphambi kokuba iqale, kwaye i-insulation, i-steering kunye nesekethe yombane ye-motor kufuneka ihlolwe emva kokuqinisekisa ukuba isibambo sikwi-manual position.
Indlela yokusebenza echanekileyo yevalve yesandla
Ivalve ye-Manual yeyona valve isetyenziswa kakhulu, ivili layo lesandla okanye isiphatho siyilwe ngokuhambelana nabasebenzi abaqhelekileyo, kuthathelwa ingqalelo ukomelela komphezulu wokutywina kunye namandla okuvala ayimfuneko.Ngoko ke, i-lever ende okanye i-spanner ende ayinakusetyenziselwa ukuhamba.Abanye abantu baqhele ukusebenzisa isipanela, kwaye kufuneka banikele ingqalelo kuyo.Xa uvula i-valve, amandla kufuneka azinzile ukuphepha amandla amaninzi, okubangela ukuba i-valve ivule kwaye ivale.Amandla kufuneka azinzile kwaye angabi neempembelelo.Ezinye iindawo zeevalvu zoxinzelelo oluphezulu ezinempembelelo yokuvula nokuvalwa ziqwalasele ukuba amandla empembelelo ayilingani naleyo yeevalvu ngokubanzi.
Xa i-valve ivuliwe ngokupheleleyo, i-handwheel kufuneka iguqulwe kancinane ukwenza imisonto iqine ukuphepha ukukhulula kunye nomonakalo.Kwiivalvu zesikhondo ezinyukayo, khumbula ukuma kwesiqu xa sivuleke ngokupheleleyo kwaye sivalwe ngokupheleleyo, ukuze uthintele ukubetha kumbindi ongaphezulu ofileyo xa uvulwe ngokupheleleyo.Kukulungele ukujonga ukuba iyinto eqhelekileyo xa ivalwe ngokupheleleyo.Ukuba ivalve iyawa, okanye ivalve core itywine phakathi kobutyobo obukhulu obufakwe, indawo yesikhondo sevalve evalwe ngokupheleleyo iya kutshintsha.Umphezulu wokutywina wevalve okanye umonakalo owenziwe ngesandla.
Uphawu lokuvula i-valve: xa i-groove kumphezulu we-valve yesikhondo se-valve yebhola, ivalve yebhabhathane kunye nevalve yeplagi ihambelana nomjelo, ibonisa ukuba ivalve ikwindawo evulekileyo epheleleyo;xa i-valve stem ijikeleziswa ngakwesobunxele okanye ekunene ngama-90. I-groove i-perpendicular kumjelo, ebonisa ukuba i-valve ikwindawo evaliweyo ngokupheleleyo.Enye ivalve yebhola, ivalve yebhabhathane, ivalve yeplagi enezitshintshi kunye netshaneli emeleneyo ukuze ivuleke, ime nkqo ukuvala.Ukusebenza kweendlela ezintathu kunye neendlela ezine kuya kwenziwa ngokuhambelana namanqaku okuvula, ukuvala kunye nokubuyisela umva.Susa isiphatho esishukumayo emva kokusebenza.
Indlela yokusebenza echanekileyo yevalve yokhuseleko
I-valve yokhuseleko iphumelele uvavanyo loxinzelelo kunye noxinzelelo oluqhubekayo ngaphambi kokufakwa.Xa ivalve yokhuseleko isebenza ixesha elide, umqhubi kufuneka anikele ingqalelo ukujonga ivalve yokhuseleko.Ngethuba lokuhlolwa, abantu kufuneka baphephe i-valve yokukhusela i-valve yokukhusela, bajonge uphawu olukhokelayo lwevalve yokhuseleko, bakhuphe i-valve yokukhusela nge-wrench ngesandla, bayivule kanye ngexesha lokususa ukungcola kunye nokuqinisekisa ukuguquguquka kwevalve yokhuseleko.
Indlela echanekileyo yokusebenza kwevalve yokukhupha amanzi
Ivalve yokukhupha amanzi kulula ukuba ivalwe ngamanzi kunye nolunye ubutyobo.Xa iqaliswa, qala uvule ivalve yokugungxula kwaye ugungxule umbhobho.Ukuba kukho umbhobho we-bypass, i-valve ye-bypass ingavulelwa ukutshatyalaliswa kwexesha elifutshane.Kwivalve ye-drain ngaphandle kombhobho wokugungxula kunye nombhobho we-bypass, ivalve yokukhupha ingasuswa.Emva kokuvula i-valve yokugungxula, vala ivalve yokuvala, faka ivalve yokukhupha amanzi, kwaye emva koko uvule ivalve yokuvala ukuqala ivalve yokukhupha.
Ukusebenza ngokuchanekileyo kwevalve yokunciphisa uxinzelelo
Phambi kokuba uqalise ivelufa yokunciphisa uxinzelelo, ivalve yokudlula okanye ivalve yokugungxulwa kufuneka ivulwe ukucoca ukungcola kumbhobho.Emva kokuba umbhobho ugungxulwe, ivalve yokudlula kunye nevalve yokugungxula iya kuvalwa, emva koko ivalve yokunciphisa uxinzelelo iya kuqalwa.Kukho ivalve phambi kwevalve yokunciphisa uxinzelelo lomphunga, ekufuneka ivulwe kuqala, emva koko uvule kancinci ivalve yokuvala emva kwevalve yokunciphisa uxinzelelo, kwaye ekugqibeleni uvule ivalve yokusika phambi kwevalve yokunciphisa uxinzelelo. .Emva koko, jonga ii-gauges zoxinzelelo ngaphambi nangemva kwe-valve yokunciphisa uxinzelelo, kwaye ulungelelanise i-screw yokulungelelanisa i-valve yokunciphisa uxinzelelo ukwenza uxinzelelo emva kwevalve lufikelele kwixabiso lokuseta.Emva koko uvule ngokucothayo ivalve yokuvala emva kwevalve yokunciphisa uxinzelelo ukulungisa uxinzelelo olusemva kwevalve ide ibe yonelisayo.Lungisa i-screw yokulungelelanisa kwaye uvale i-cap yokukhusela.Umzekelo
Ukuba ivalve yokunciphisa uxinzelelo iyasilela okanye idinga ukulungiswa, ivalve ye-bypass kufuneka ivulwe ngokucothayo, kwaye ivalve yokusika phambi kwevalve kufuneka ivalwe kwangaxeshanye.Ivalve ye-bypass kufuneka ilungelelaniswe ngokufanelekileyo ngesandla ukwenza uxinzelelo emva kwevalve yokunciphisa uxinzelelo oluzinzileyo kwixabiso elimiselweyo.Emva koko uvale ivalve yokunciphisa uxinzelelo, uyitshintshe okanye uyilungise, kwaye ubuyele kwisiqhelo.
Ukusebenza ngokuchanekileyo kwevalve yokukhangela
Ukuze ugweme amandla aphezulu empembelelo eyenziwe ngeli xesha xa i-valve yokukhangela ivaliwe, i-valve kufuneka ivalwe ngokukhawuleza, ukwenzela ukuba kuthintelwe ukubunjwa kwe-backflow velocity enkulu, eyona nto ibangela uxinzelelo lwempembelelo xa i-valve ivalwe ngokukhawuleza. .Ngoko ke, isantya sokuvala sevalve kufuneka sihambelane nesantya sokunciphisa umlambo osezantsi ngokuchanekileyo.
Ukuba uluhlu lwesantya somsinga osezantsi sikhulu, ubuncinci besantya asanelanga ukunyanzela ukuvalwa ukuba kumiswe ngokuzinzileyo.Kule meko, ukunyakaza kwenxalenye yokuvala kunokuvinjelwa ngu-damper ngaphakathi kwinqanaba elithile lesenzo sayo.Ukushukuma okukhawulezayo kwamacandelo okuvala kuya kwenza ukuba iindawo ezihambayo zevalve zinxibe ngokukhawuleza, okukhokelela ekungaphumeleli kwangaphambili kwevalve.Ukuba i-medium is pulsating flow, ukungcangcazela ngokukhawuleza kwenxalenye yokuvala kubangelwa ukuphazamiseka okugqithisileyo okuphakathi.Kule meko, i-valve yokutshekisha kufuneka ibekwe kwindawo apho ukuphazamiseka okuphakathi kuncinci.
