Iingcebiso
Umgangatho ophezulu we-Naliti yeValve inokusebenza ngesandla okanye ngokuzenzekelayo.Iivalvu zeenaliti ezisebenza ngesandla zisebenzisa ivili lesandla ukulawula umgama phakathi kweplunger kunye nesitulo sevalve.Xa ivili lesandla lijikelwe kwicala elinye, iplunger iyaphakanyiswa ukuze ivule ivalve kwaye ivumele ulwelo ukuba ludlule.Xa ivili lesandla lijikelwa kwelinye icala, i-plunger isondela kufutshane nesihlalo ukucutha isantya sokuhamba okanye ukuvala ivalve.
Iivalvu zeenaliti ezizenzekelayo ziqhagamshelwe kwi-hydraulic motor okanye i-air actuator evula ngokuzenzekelayo kwaye ivale ivalve.Injini okanye i-actuator iya kulungelelanisa indawo yeplunger ngokwezibali-xesha okanye idatha yokusebenza yangaphandle eqokelelwe xa kubekwa iliso koomatshini.
Zombini iivalvu zeNaliti ezisebenza ngesandla kunye nezizenzekela zibonelela ngolawulo oluchanekileyo lomyinge wokuhamba.I-handwheel ifakwe kakuhle, oku kuthetha ukuba kuthatha amaxesha amaninzi ukulungisa indawo yeplunger.Ngenxa yoko, i-valve yenaliti inokukunceda ukuba ulawule kakuhle izinga lokuhamba kwamanzi kwinkqubo.
Iimpawu zeValve yenaliti Izinto kunye neMifanekiso
1. Ivalve yenaliti
2. Yenziwe ngentsimbi ye-ASTM A479-04 (iBakala 316)
3.Isiphelo esinemisonto ngokwe ASME B 1.20.1(NPT)
4. UMax.Uxinzelelo lokuSebenza 6000 psi kwi-38 °C
5.Ubushushu bokusebenza -54 ukuya ku-232°C
6.Isitshixo sebhonethi yokhuseleko kuthintela ilahleko ngempazamo.
7.Uyilo lokuhlala ngasemva lukhusela ukupakisha kwindawo evulekile ngokupheleleyo.
