Zithini iikhrayitheriya zokukhetha iivalves

Iikhrayitheriya zokukhetha kweVoveve: Ukuqwalaselwa kobungakanani obuninzi ukuqinisekisa ukuba inkqubo

Ukukhetha i-veli kufuneka kuthathelwe ingqalelo izinto ezininzi ukufezekisa iimfuno zezinto ezikhuselekileyo, ezizinzileyo nefanelekileyo yenkqubo. Iikhrayitheriya eziphambili zokukhetha zezi zilandelayo:

Iimpawu ze-1.fluid

Uhlobo lohlobo lwamanzi: kwiigesi, iigesi ngokubanzi zingazikhetha iiValk zesango, i-valuves, njl. Iigesi ezinokutsha kunye nokuqhushumba kufuneka zikhethwe ngokutywina okuhle kunye nokungavisisani komlilo kunye nokuxhaphaza, njenge vallo zebhola kunye nezakhiwo ezinganyangekiyo zomlilo. Ngokuphathelele ulwelo, kukho ukhetho lwamanzi acocekileyo; Ulwelo olunamasuntswana anezilonda, i-valve engaphili njengeeVolves kufuneka zikhethwe ukukhusela ukunxiba kunye nokubhloka; Ulwelo olusebenzayo lufuna i-valves eyenziwe ngezinto ezinganyangekiyo, ezinjengeentsimbi zentsimbi kunye neplastikhi, kuxhomekeke kwi-Preum.

Iqondo lokushisa elinamanzi: Amaqondo obushushu amaqondo obushushu (ngaphezulu kwe-450 ℃) kufuneka akhethe i-valves enganyangekiyo yobushushu, njenge valbels yesango lobushushu obuphezulu. Iqondo lokushisa eliphantsi (ngezantsi -40 ℃) lifune i-valves ezinobunzima obuphantsi, kunye neevila zeqondo lobushushu eziphantsi zisetyenziswa rhoqo kwi-nitrogen yolwelo kunye neepyline zeoksijini.

I-fluid yoxinzelelo oluphantsi (lungaphantsi kwe-1.6MPA), i-valve yezifundo eziqhelekileyo zinokukhethwa; Uxinzelelo oluphezulu (uxinzelelo oluphakathi 1.6-10MPA, uxinzelelo oluphezulu lungaphezulu kwe-10MPA) ifuna ukusetyenziswa kweevalva eziphezulu, ezinje ngeevavaphu eziphezulu ezivaliweyo.

I-fastcofity ye-fluid: i-slids ephantsi ye-viscosity inoluhlu olubanzi lokukhetha; I-Viscosity ephezulu ye-Viscosity ixhaphake kwi-Bekion kunye nebhloko, ke iyimfuneko ukukhetha i-valve yesango kunye neevalva zebaliti kunye ne-valves ephezulu kunye nebhlogo ephantsi. Ukuba kukho imfuneko, abaphathi bombane okanye i-pneumatic kufuneka basetyenziswe.

2. Umsebenzi weProcess

Ukunqunyulwa komsebenzi: I-valve yesango ihlangeneyo ephantsi, ukuvula okulula nokuvala, kwaye kufanelekile kwimibhobho yobume obukhulu; Ivalve evaliweyo itywinwe kwaye ilungele izihlandlo ezineemfuno eziphezulu zokutywina; Ukutshintsha kwebala lebhola ngokukhawuleza kwaye lityhutyha ngokuthembekileyo, lilungele ukusebenza rhoqo nokuvalwa; I-vally zebhabhathane linolwakhiwo olulula kunye nevolumu encinci, ibenza balungele imibhobho yoxinzelelo oluphezulu.

Umsebenzi owenziwayo: Xa ukuhamba kunye nokucinezelwa kunye nengcinezelo kufuneka ilungiswe, ivalve elawulayo inokusetyenziswa ngokuzenzekelayo ihlengahlengise ngokuzenzekelayo ukuvulwa komqondiso wolawulo, ukufezekisa ulawulo oluchanekileyo. Kukho iintlobo ezifana nesihlalo esinye, isitulo esiphindwe kabini, kunye nemikhono elawula iivalves.

Umsebenzi wokujonga ukubuyisela umva, ukuphakamisa ivalve enokutywina okuhle kodwa ukuchasana okuphezulu kwe-fluid, efanelekileyo kwimibhobho yokufakelwa kwamanzi amancinci; I-swing jonga i-valves inamazwe asezantsi kwaye ilungele imibhobho yofakelo ethe tyaba.

Umsebenzi wokuKhusela uKhuseleko: Ivalve yokhuseleko ithintela izixhobo okanye i-pubiline uxinzelelo ukusuka kwixabiso elichaziweyo, kwaye ivulwa ngokuzenzekelayo kwi-sleid xa uxinzelelo luphezulu kakhulu; Idiski yokuqhushumba sisixhobo sokhuseleko esilahlekileyo esikhuphayo kwaye sikhulule ulwelo xa uxinzelelo lufikelela kwixabiso lokuqhushumba.
