Imigaqo kunye neenkcazo ngokuhambelana ne-EN ISO 4126-1
1) I-valve yokhuseleko
Ivalve ethe ngokuzenzekelayo, ngaphandle koncedo lwawo nawaphi na amandla ngaphandle kwalowo wolwelo oluchaphazelekayo, ikhupha ubuninzi bolwelo ukuze kuthintelwe ukugqithiswa koxinzelelo olukhuselekileyo olumiselwe kwangaphambili, kwaye eyilelwe ukuvala kwakhona nokuthintela ukuhamba okungaphezulu kolwelo emva koxinzelelo. iimeko zoxinzelelo oluqhelekileyo lwenkonzo zibuyiselwe.
2) Beka uxinzelelo
Uxinzelelo olumiselweyo apho ivalve yokhuseleko phantsi kweemeko zokusebenza iqala ukuvula.
Ukuzimisela koxinzelelo olubekiweyo: ukuqala kokuvulwa kwevalve yokhuseleko (umzuzu xa umbane uqala ukuphuma
ukusuka kwivalve yokhuseleko, ngenxa yokufuduswa kwediski ekudibaneni nendawo yokutywina yesihlalo) inokumiselwa ngeendlela ezahlukeneyo (ukuphuphuma, ipop, amaqamza), ezo zamkelwe BESA Zilandelayo:
- ukusetwa ngegesi (umoya, i-nitrogen, i-helium): ukuqala kokuvulwa kwevalve yokhuseleko kunqunywe
- ngokumamela isithonga sokuqala esivakalayo esibangelwe
- ngokuphuphuma kolwelo lovavanyo oluphuma kwisitulo sevalvu;
- ukusetwa ngolwelo (amanzi): isiqalo sokuvuleka kwesivalo sokhuseleko simiselwa ngokubona ngokubona ukuhamba kolwelo oluzinzile oluphuma kwisitulo sevalve.
Uxinzelelo shall kulinganiswa usebenzisa i-gauge ye-pressure gauge yeklasi yokuchaneka kwe-0.6 kunye nomlinganiselo opheleleyo we-1.25 ukuya kuma-2 amaxesha oxinzelelo oluza kulinganiswa.
3) Uxinzelelo oluphezulu oluvumelekileyo, i-PS
Uxinzelelo oluphezulu apho isixhobo siyilelwe njengoko kuchaziwe ngumenzi.
4) Uxinzelelo olugqithisileyo
Ukunyuka koxinzelelo phezu koxinzelelo olubekiweyo, apho ivalve yokhuseleko ifumana ukunyuswa okuchazwe ngumenzi, ngokuqhelekileyo ibonakaliswe njengepesenti yoxinzelelo olumiselweyo.
5) Ukubuyisela kwakhona uxinzelelo
Ixabiso loxinzelelo lwe-inlet static apho i-disc iphinda iphinde idibanise nesihlalo okanye apho ukuphakama kuba ngu-zero.
I-6) Uxinzelelo lovavanyo oluhlukileyo olubandayo
Uxinzelelo lwe-Inlet static apho ivalve yokhuseleko isetelwe ukuba iqalise ukuvula kwibhentshi.
7) Ukunciphisa uxinzelelo
Uxinzelelo olusetyenziselwa ukulinganisa ivalve yokhuseleko enkulu okanye elingana noxinzelelo olubekiweyo kunye noxinzelelo olugqithisileyo.
I-8) Uxinzelelo lwasemva olwakhiweyo
Uxinzelelo olukhoyo kwi-outlet yevalve yokhuseleko olubangelwa ukuhamba ngevalve kunye nenkqubo yokukhupha.
9) Uxinzelelo lwangasemva oluphezulu
Uxinzelelo olukhoyo kwindawo yokuphuma yevalve yokhuseleko ngexesha apho isixhobo kufuneka sisebenze.
10) Phakamisa
Olona hambo lwediski yevalve kude nendawo evaliweyo.
11) Indawo yokuhamba
Ubuncinane bommandla wokuqukuqela onqamlezayo (kodwa ingeyiyo indawo yomkhusane) phakathi kwendawo yokungena kunye nesitulo esetyenziselwa ukubala umthamo wokuqukuqela kwethiyori, ngaphandle kokutsalwa nakwesiphi na isithintelo.
12) Umthamo oqinisekisiweyo (ukhupha).
Inxalenye yomthamo olinganisiweyo ovunyelweyo ukuba usetyenziswe njengesiseko sokufakwa kwevalve yokhuseleko.
