l Ivalve yenaliti luhlobo lwevalve ehlengahlengiswayo, esetyenziswa ngokubanzi, njengokusika umgama wokusika amadangatye, kunye neqhosha lokulungelelanisa ubushushu bomlilo yivalve yenaliti. Ivalve yenaliti yinxalenye ebalulekileyo yesixokelelwano sombhobho womlinganiselo wesixhobo, esiquka ikakhulu ivalve yeglowubhu kunye nevalve yebhola. Umsebenzi wayo kukuvula okanye ukunqumla umbhobho. I-spool yevalve yenaliti yicone ebukhali kakhulu, njengenaliti efakwe kwisihlalo, kungoko igama.
l I-valve yokumisa, eyaziwa ngokuba yi-valve yokuvala, i-valve yokutywina ngokunyanzeliswa, ngoko xa i-valve ivaliwe, uxinzelelo kufuneka lufakwe kwi-disc ukukhusela ukuvuza kwendawo yokutywina ngokunyanzeliswa. Xa i-medium ingena kwi-valve ukusuka ngaphantsi kwe-disc ye-valve, ukuchasana okuza kunqotshwa ngamandla okusebenza kukungqubuzana phakathi kwesiqu kunye nokupakisha kunye nokunyanzeliswa okwenziwa ngoxinzelelo lwe-medium. Amandla okuvala i-valve inkulu kunoko ukuvula i-valve, ngoko ububanzi besiqu kufuneka bube bukhulu, ngaphandle koko i-stem iya kugoba.
l Amanyathelo okhuseleko ofakelo
1. Isikhundla sofakelo, ukuphakama kunye nolwalathiso lwe-inlet kunye ne-outlet kufuneka ihlangabezane neemfuno zoyilo. Isalathiso sokuhamba okuphakathi siya kuhambelana necala lotolo oluphawulwe kumzimba wevalvu, kwaye uqhagamshelo luya kuba luqilima kwaye luqine.
2. I-valve kufuneka ihlolwe ngokubonakalayo ngaphambi kokufakwa, kwaye ipleyiti yegama le-valve iya kuhambelana nemimiselo yomgangatho welizwe langoku "amanqaku e-valve jikelele" GB 12220. Kwi-valve enoxinzelelo olusebenzayo olungaphezu kwe-1.0 MPa kunye nomsebenzi wokusika kumbhobho oyintloko, uvavanyo lwamandla kunye nokuqina luya kuqhutywa ngaphambi kokufakwa, kwaye i-valve ingasetyenziselwa kuphela emva kokuba ifanelekile. Ngethuba lovavanyo lwamandla, uxinzelelo lovavanyo luya kuba ngamaxesha angama-1.5 oxinzelelo oluncinci, ubude bexesha abuyi kuba ngaphantsi kwe-5min, kunye negobolondo le-valve kunye nokupakishwa kuya kufaneleka ukuba akukho kuvuza. Ngethuba lokuvavanywa koxinzelelo, uxinzelelo lovavanyo luyi-1.1 ngamaxesha oxinzelelo oluncinci, kwaye ubude bexesha lokuvavanya luhlangabezana neemfuno ze-GB 50243.
