Ukufakwa kweama-valve esango
I-valve yesango, eyaziwa nangokuthi i-valve yesango, ukusetshenziswa kwesango ukulawula ukuvuleka nokuvalwa kwevalvu, ngokushintsha ingxenye enqamulayo ukuze kulungiswe ukugeleza kwepayipi nokuvula nokuvala ipayipi.Amavalvu esango asetshenziselwa ikakhulukazi ipayipi lokuvula noma ukuvala ngokugcwele kwe-fluid medium.Ukufakwa kwe-valve yesango ngokuvamile azikho izidingo zokuqondisa, kodwa akukwazi ukufakwa sibheke phansi.
Ukufakwa kwei-valve yomhlaba
I-valve ye-globe ukusetshenziswa kwe-disc ukulawula ukuvulwa nokuvalwa kwe-valve.Ngokushintsha igebe phakathi kwe-disc nesihlalo, okungukuthi, ukushintsha usayizi wesigaba sesiteshi ukulungisa ukugeleza okuphakathi noma ukusika indlela ephakathi.Kumelwe kuqashelwe ukugeleza kokuqondisa lapho kufakwa ama-valve embulunga.
Isimiso okufanele silandelwe lapho kufakwa i-valve yembulunga ukuthi uketshezi olusepayipini ludlula embotsheni ye-valve ukusuka phansi kuye phezulu, okuvame ukubizwa ngokuthi “phansi kuye phezulu”, futhi aluvunyelwe ukufakwa ngokuhlehla.
Hlola i-valveukufakwa
I-valve yokuhlola, eyaziwa nangokuthi i-valve yokuhlola, i-valve yokuhlola, i-valve engaphansi komehluko wengcindezi ngaphambi nangemva kokuba i-valve ivuleke futhi ivalwe ngokuzenzakalelayo, indima yayo ukwenza i-medium kuphela isiqondiso sokugeleza, nokuvimbela ukugeleza okuphakathi emuva.Hlola i-valve ngokuya ngesakhiwo sayo esihlukene, kukhona uhlobo lokuphakamisa, ukushwiba novemvane.I-valve yokuhlola yokuphakamisa kanye namaphoyinti avundlile naqondile.Hlola ukufakwa valve, futhi kufanele sinake ukugeleza medium, ayikwazi ukufakwa reverse.
Ukufakwa kwei-valve yokunciphisa ingcindezi
I-valve yokunciphisa ingcindezi ilungiswa ukuze kuncishiswe ingcindezi yokungena emshinini wokuphuma odingekayo, futhi incike emandleni omthombo ngokwawo, ukuze ingcindezi yokuphuma igcine ngokuzenzakalelayo i-valve ezinzile.
Ngokombono we-fluid mechanics, i-valve yokunciphisa ingcindezi ingukumelana kwendawo kungashintsha isici se-throttle, okungukuthi, ngokushintsha indawo ye-throttle, izinga lokugeleza kanye noshintsho lwamandla e-kinetic uketshezi, okuholela ekulahlekelweni kwengcindezi ehlukene, ukuze kuzuzwe. inhloso yokuwohloka komqondo.Bese uthembele ekulungisweni kwesistimu yokulawula nokulawula, ukuze ukushintshashintsha kwengcindezi ye-valve kanye nebhalansi ye-spring force, ukuze ingcindezi ye-valve kuhlu oluthile lwephutha ukugcina njalo.
1. Iqembu lama-valve okwehlisa ukucindezela elifakwe mpo ngokuvamile lihlelwa eduze kodonga endaweni ephakeme efanele ukusuka phansi;Amasethi ama-valve okunciphisa ingcindezi abekwe ngokuvundlile ngokuvamile afakwa endaweni yokusebenza ehlala njalo.
2. Ukusetshenziswa kwensimbi ngokulandelana kuma-valve okulawula amabili (okuvame ukusetshenziselwa i-valve yeglobhu) ngaphandle kodonga, ukwakha ubakaki, ipayipi le-bypass liphinde linamathele kubakaki, izinga kanye nokuqondanisa.
3. Ivalvu yokunciphisa ingcindezi kufanele ifakwe iqonde epayipini elivundlile, ingatsheki, umcibisholo osemzimbeni wevalvu kufanele ubheke lapho kugeleza khona okuphakathi, ungafakiwe.
4. I-valve yokumisa kanye ne-gauge ye-high and low pressure gauge kufanele ifakwe ezinhlangothini zombili ukuze kugcinwe ukuguqulwa kwengcindezi ngaphambi nangemva kwe-valve.Ububanzi bepayipi ngemva kwevalve yokunciphisa ingcindezi kufanele bube ngu-2#-3# mkhulu kunobubanzi bepayipi lokungena ngaphambi kwevalvu, futhi ufake ipayipi lokudlula ukuze lilungiswe.
5. Ipayipi yokulinganisa ingcindezi ye-valve yokunciphisa ingcindezi yefilimu kufanele ixhunywe kwipayipi yokucindezela okuphansi.Ivalvu yokuphepha kufanele isethelwe ipayipi lomfutho ophansi ukuze kuqinisekiswe ukusebenza okuphephile kohlelo.
6. Uma isetshenziselwa ukuchithwa kwe-steam, ipayipi yokudonsa kufanele isethwe.Ezinhlelweni zamapayipi ezidinga izinga eliphezulu lokuhlanzwa, isisefo kufanele sibekwe phambi kwevalvu yokunciphisa ingcindezi.
7. Ngemuva kokufakwa kweqembu le-valve yokunciphisa ingcindezi, ukuhlolwa kwengcindezi, ukugeza nokulungiswa kufanele kwenziwe ku-valve yokunciphisa ingcindezi kanye ne-valve yokuphepha ngokuvumelana nezidingo zokuklama, futhi uphawu olulungisiwe kufanele lwenziwe.
Lapho ushayela i-valve yokunciphisa ukucindezela, vala i-valve yokungena ye-valve yokunciphisa ingcindezi bese uvula i-valve yokuguquguquka ukuze iguqe.
