Wazini ngamabhodi ayizimpumputhe?

Igama elisemthethweni lepuleti eliyimpumputhe lithii-flangei-cap, enye ebizwa nangokuthi i-blind flange noma ipulaki yepayipi. Kuyi-ai-flangengaphandle kwembobo phakathi, esetshenziselwa ukuvala umlomo wepayipi. UMSEBENZI UFANA NEkhanda nesivalo seshubhu, ngaphandle kokuthi uphawu oluyimpumputhe luyithuluzi lokuvala elikwazi ukuvala, futhi uphawu lwekhanda alukalungeli ukuphinda luvulwe. Kunezinhlobo eziningi zendawo yokuvala, okuhlanganisa indiza, i-convex surface, i-concave ne-convex surface, i-tenon surface kanye nendawo yokuxhuma indandatho. Material: carbon steel, insimbi engagqwali, ingxubevange steel, ithusi, aluminium, PVC kanye PPR.
Ipuleti eliyimpumputhe lisetshenziselwa ikakhulukazi ukuhlukaniswa okuphelele kwendawo yokukhiqiza ukuvimbela ukukhiqizwa ukuthintwa ukuvaleka okuxekethile kwe-valve yokusika futhi kubangele ngisho nezingozi. Ipuleti eliyimpumputhe kufanele libekwe ezingxenyeni ezidinga ukuhlukaniswa, njenge-nozzle yemishini, ngaphambi nangemuva kwe-valve yokusika noma phakathi kwama-flange amabili. Ipuleti eliyimpumputhe elingu-8 livame ukutuswa. Ngokucindezela, ukuhlanza kanye nezinye izingxenye ezisetshenziswa kanyekanye nazo zingasebenzisa ipuleti lepulaki (ipuleti eliyindilinga eliyindilinga).

1. Esigabeni sokuqala sokulungiselela ukuqalisa, ukuhlolwa kwamandla noma ukuqina kwepayipi akunakukwenziwa ngesikhathi esifanayo nemishini exhunyiwe (njenge-turbine, compressor, gasifier, reactor, njll.), kanye nempumputhe. ipuleti kufanele libekwe ekuxhumekeni phakathi kwemishini kanye nepayipi.
2. Kuzo zonke izinhlobo zamapayipi wempahla yenqubo axhunywe endaweni yomngcele ngaphandle kwendawo yomngcele, lapho idivayisi ima, uma ipayipi lisasebenza, setha ipuleti eliyimpumputhe ku-valve esikiwe.
3. Uma idivayisi iwuchungechunge oluningi, ipayipi elikhulu elisuka ngaphandle kwendawo yomngcele lihlukaniswe libe izinkulungwane zamashaneli amapayipi ochungechungeni ngalunye, futhi i-valve yokunqamula yesiteshi ngasinye sepayipi isethwe ngepuleti lokunqamula.
4. Uma idivayisi idinga ukunakekelwa okuvamile, ukuhlolwa noma ukushintshaniswa okufanayo, okokusebenza okuhilelekile kudingeka kuhlukaniswe ngokuphelele, futhi ipuleti eliyimpumputhe libekwe ku-valve yokusika.
5. Uma ipayipi lokushaja nokucindezela kanye nepayipi legesi elishintshayo (njengepayipi le-nitrogen kanye nepayipi lomoya elicindezelwe) kuxhunywe namathuluzi, ipuleti eliyimpumputhe kufanele limiswe kuvalvu enqamuliwe.
6. Hlanza indawo ephansi yezinto zokusebenza namapayipi. Uma i-process medium idinga ukufakwa phakathi ohlelweni oluhlangene lokuqoqa, setha ipuleti eliyimpumputhe ngemva kwe-valve yokusika.
7. Amapuleti ayizimpumputhe noma amapulaki ocingo kufanele abekwe ngemuva kwamavalvu amapayipi okukhipha umoya, amapayipi akhipha uketshezi kanye namapayipi okusampula emishini namapayipi. Izinto ezingezona ubuthi, ezingenabungozi empilweni kanye nezinto ezingaqhumi azifakiwe.
8. Uma ukufakwa kwakhiwa ngezigaba, ipuleti eliyimpumputhe kufanele libekwe ku-valve yokusika yamapayipi axhunywe komunye nomunye, ukuze kube lula ukwakhiwa okulandelayo.
9. Uma idivayisi isekukhiqizweni okuvamile, amanye amapayipi asizayo adinga ukunqunywa ngokuphelele kufanele futhi afakwe amapuleti ayimpumputhe. ? [1]?
Izindaba ezidinga ukunakwa
1. Ngokwesisekelo sokuhlangabezana nezidingo zenqubo, setha amapuleti angaboni emehlweni ambalwa ngangokunokwenzeka.
2. Ipuleti eliyimpumputhe elimisiwe kufanele libonise ukuvuleka okuvamile noma ukuvala okuvamile.
3. Ingxenye yepuleti eliyimpumputhe elibekwe ku-valve yokusika, phezulu noma phansi komfula, kufanele kunqunywe ngokuvumelana nomphumela wokusika, izidingo zokuphepha kanye nenqubo.
