Iivalvu zidlala indima ebalulekileyo kwiindawo ezahlukeneyo zoshishino. Kwinkqubo yokusebenzisa ivalvu, ngamanye amaxesha kuya kubakho iingxaki zokuvuza, ezingayi kubangela kuphela ukuchitha amandla nezixhobo, kodwa zinokubangela nomonakalo kwimpilo yabantu nakwindalo esingqongileyo. Ke ngoko, ukuqonda izizathu zokuvuza kweevalvu kunye nezisombululo ezifanelekileyo kubalulekile ekugcineni ukusebenza okuqhelekileyo kwezixhobo kunye nokukhusela okusingqongileyo.

1. Iziqwenga zokuvala ziyawa zibangele ukuvuza

(1) Amandla okusebenza abangela ukuba inxalenye yokuvala idlule kwindawo ebekiweyo, kwaye inxalenye eqhagamshelweyo yonakele kwaye yaphukile;

(2) Izinto ezikwisixhobo sokudibanisa esikhethiweyo azifanelekanga, kwaye zingcoliswa yindlela yokunxibelelana kwaye zigugile oomatshini ixesha elide.

Indlela yokulungisa:

(1) Vala ivalvu ngamandla afanelekileyo, vula ivalvu ayinakudlula i-dead point ephezulu, emva kokuba ivalvu ivuliwe ngokupheleleyo, ivili lesandla kufuneka libuyele umva kancinci;

(2) Khetha izinto ezifanelekileyo, izibophelelo ezisetyenziselwa ukunxibelelana phakathi kwenxalenye yokuvala kunye nesiqu sevalvu kufuneka zikwazi ukumelana nokugqwala kwesixhobo, kwaye zibe namandla athile oomatshini kunye nokumelana nokuguguleka.

2. Ukuvuza kwindawo yokuzalisa (kunokwenzeka kakhulu)

(1) Ukukhetha i-filler akuchanekanga, akumelani nokugqwala kwe-medium, akuhlangabezani ne-valve yoxinzelelo oluphezulu okanye i-vacuum, ubushushu obuphezulu okanye ubushushu obuphantsi;

(2) Ukupakisha akufakelwanga ngokuchanekileyo, kwaye kukho iziphene ezifana nokuveliswa okuncinci, i-spiral coil joint engalunganga, iqinile kwaye ikhululekile;

(3) Isizalisi sidlula ixesha lokusetyenziswa, sigugile, silahlekelwa kukuqina;

(4) Ukuchaneka kwesiqu sevalvu akuphezulu, ukugoba, ukubola, ukuguguleka kunye nezinye iziphene;

(5) Inani leendandatho zokupakisha alanelanga, kwaye i-gland ayicinezelwanga kakuhle;

(6) I-gland, i-bolt, kunye nezinye iindawo zonakele, kangangokuba i-gland ayinakucinezelwa;

(7) Ukusebenza okungafanelekanga, amandla agqithisileyo, njl.njl.;

(8) I-gland igobile, umsantsa ophakathi kwe-gland kunye nesiqu se-valve mncinci kakhulu okanye mkhulu kakhulu, nto leyo ebangela ukuguguleka kwesiqu se-valve kunye nomonakalo wokupakisha.

Indlela yokulungisa:

(1) Izinto kunye nohlobo lwesizalisi kufuneka zikhethwe ngokweemeko zokusebenza;

(2) Faka ukupakisha ngokuchanekileyo ngokwemigaqo efanelekileyo, ukupakisha kufuneka kubekwe kwaye kucinezelwe kwisangqa ngasinye, kwaye ijoyinti mayibe yi-30C okanye i-45C;

(3) Ixesha lokusetyenziswa lide kakhulu, ukuguga, ukupakisha okonakeleyo kufuneka kutshintshwe ngexesha elifanelekileyo;

(4) Isiqu sevalvu kufuneka silungiswe size silungiswe emva kokugoba nokuguguleka, kwaye ezonakeleyo kufuneka zitshintshwe ngexesha elifanelekileyo;

(5) Ukupakisha kufuneka kufakwe ngokwenani elichaziweyo leendandatho, i-gland kufuneka iqiniswe ngokulinganayo nangokulinganayo, kwaye umkhono wokucinezela kufuneka ube nomsantsa wokuqinisa ongaphezulu kwe-5mm;

(6) Ii-caps, ii-bolts kunye nezinye iindawo ezonakeleyo kufuneka zilungiswe okanye zitshintshwe ngexesha elifanelekileyo;

(7) Kufuneka balandele iinkqubo zokusebenza, ngaphandle kokuchaphazeleka kwevili lesandla, ukuze bakhawulezise ukusebenza kwamandla aqhelekileyo;

(8) I-gland bolt kufuneka iqiniswe ngokulinganayo nangokulinganayo. Ukuba umsantsa ophakathi kwe-gland kunye ne-valve stem umncinci kakhulu, umsantsa kufuneka wonyuswe ngokufanelekileyo; i-gland kunye ne-stem clearance zikhulu kakhulu, kufuneka zitshintshwe.
