Ivalvu yokuphosa iphoswa kwivalvu, umgangatho woxinzelelo lwevalvu yokuphosa ngokubanzi uphantsi kakhulu (njengePN16, PN25, PN40, kodwa kukwakho noxinzelelo oluphezulu, lunokuba yi-1500Lb, 2500Lb), uninzi lwe-caliber lungaphezulu kwe-DN50. Ivalvu yokuphosa yenziwe nge-caliber, isetyenziswa ngokubanzi kwimibhobho yomgangatho ophezulu, i-caliber incinci kakhulu, ngokubanzi ingaphantsi kwe-DN50.

Okokuqala, ukuphosaivalvu
1, ukuphosa: kukunyibilikisa isinyithi sibe lulwelo oluhlangabezana neemfuno ezithile kwaye luphoswe kwisikhunta, emva kokuphola nokuqina, unyango lokucoca ukuze kufunyanwe imo, ubungakanani kunye nokusebenza kwangaphambili kwenkqubo yokuphosa (iinxalenye okanye ezingenanto). Ubuchwepheshe obusisiseko boshishino lwanamhlanje lokuvelisa oomatshini.

2, imveliso yokuphosa engabizi kakhulu, ukuze ifane neentlobo ezintsonkothileyo, ingakumbi iindawo ezixineneyo ezingaphakathi, okungaphezulu kunokubonisa uqoqosho lwayo; Kwangaxeshanye, iyakwazi ukuguquguquka ngokubanzi kwaye ineempawu ezingcono zoomatshini.

3, kodwa imveliso yokuphosa yayifuna izinto (ezifana nesinyithi, umthi, ipetroli, izinto zokubumba, njl.njl.) kunye nezixhobo (ezifana nesithando sesinyithi, umatshini wokuxuba isanti, umatshini wokubumba, umatshini wokwenza umbindi, umatshini wokuwa kwesanti, umatshini wokuqhumisa isibhamu, ipleyiti yesinyithi esityhidiweyo, njl.njl.) ngaphezulu, kwaye iya kuvelisa uthuli, igesi enobungozi kunye nengxolo kunye nongcoliseko lokusingqongileyo.

4, ukuphosa yinkqubo yokucubungula isinyithi eshushu eqale yabonwa ngumntu, uphuhliso lwesantya sokuphosa lukhawuleza kakhulu, luphuhlise isinyithi esinamaqhuqhuva, isinyithi esithambileyo esithambileyo, isinyithi esingenasici esinekhabhoni esezantsi kunye nobhedu lwe-aluminium, i-aluminium silicon, i-aluminium magnesium alloy, i-titanium, i-nickel base alloy kunye nezinye izinto zesinyithi eziphosayo, kunye nenkqubo entsha yonyango lokuzalisa isinyithi esingwevu. Emva kweminyaka engama-50, kwavela imodeli yoxinzelelo oluphezulu lwesanti emanzi, imodeli yesanti yokuqinisa iikhemikhali kunye nokwenza isiseko, imodeli yoxinzelelo olubi kunye nokunye ukuphosa okukhethekileyo, ukucoca ukudubula kunye nezinye iiteknoloji ezintsha.

5, kukho iintlobo ezininzi zokuphosa, ngokwendlela yokumodela, yahlulwe ngokwesiko yaba: (1) ukuphosa isanti eqhelekileyo, kuquka isanti emanzi, isanti eyomileyo kunye nesanti yokuqinisa iikhemikhali. 3. ② Ukuphosa okukhethekileyo, izixhobo zokubumba zePress zingahlulwa zibe yisanti yeminerali yendalo njengezixhobo zokubumba ezikhethekileyo (umz., ukuphosa utyalo-mali, ukuphosa isikhunta, ukuphosa isikhunta seqokobhe, ukuphosa uxinzelelo olubi, ukuphosa isikhunta, ukuphosa isikhunta se-ceramic, njl. njl.) kunye nesinyithi njengezixhobo eziphambili zokubumba ezikhethekileyo (ezifana nokuphosa isikhunta sesinyithi, ukuphosa uxinzelelo, ukuphosa okuqhubekayo, ukuphosa uxinzelelo oluphantsi, ukuphosa i-centrifugal, njl. njl.).

6, inkqubo yokuphosa idla ngokubandakanya: (1) i-cast (izikhongozeli) yenza isinyithi esilulwelo sinyibilike, ukuphosa ngokwezixhobo kunokwahlulwahlulwa kube yi-mold yesanti, isinyithi, i-ceramic, udaka, i-graphite, njl., inokwahlulwa ngokusetyenziswa, uhlobo oluhlala ixesha elide nolusisigxina, umgangatho wokulungiselela i-mold zezona zinto ziphambili ezichaphazela umgangatho wokuphosa; (2) ukunyibilika nokuphosa isinyithi, isinyithi esiphosayo (i-alloy ephosayo) ikakhulu zi-cast iron, i-cast iron kunye ne-cast non-ferrous alloy; Unyango kunye nokuhlolwa kwe-cast, unyango lwe-cast oluquka ukususwa kwe-core kunye ne-cast umphezulu wemizimba yangaphandle, ukususwa kwe-riser yokuthulula, i-shovel grinding burr kunye ne-seam kunye nezinye izinto ezibonakala kunye nonyango lobushushu, iplastiki, unyango lwe-rust kunye ne-rough processing.
