Ngaphansi kwezimo ezijwayelekile, amavalvu ezimboni awawenzi ukuhlolwa kwamandla uma esetshenziswa, kodwa ngemva kokulungisa umzimba wevalvu kanye nesembozo sevalvu noma umonakalo wokugqwala komzimba wevalvu kanye nesembozo sevalvu kufanele enze ukuhlolwa kwamandla. Kumavalvu okuphepha, ingcindezi yokusetha kanye nengcindezi yokubuya kanye nezinye izivivinyo kufanele zihambisane nemigomo nemigomo efanele. Ivalvu kufanele ihlolwe amandla nokuqina ngaphambi kokufakwa. Amavalvu aphakathi nendawo kanye nomfutho ophezulu kufanele ahlolwe. Ukuhlolwa komfutho wamavalvu asetshenziswa kakhulu amanzi, uwoyela, umoya, umusi, i-nitrogen, njll. Zonke izinhlobo zamavalvu ezimboni kufaka phakathi izindlela zokuhlola umfutho wamavalvu omoya yilezi ezilandelayo:

1.I-valve yebholaindlela yokuhlola ingcindezi

Ukuhlolwa kwamandla e-valve yebhola yomoya kufanele kwenziwe esimweni sokuvuleka kwengxenye yebhola.

(1)Ibhola elintantayoisivivinyo sokuqina kwevalvu: ivalvu ivulekile ingxenye, umkhawulo owodwa ufakwa endaweni yokuhlola, kanti omunye umkhawulo uvaliwe; Phendula ibhola izikhathi eziningana, vula umkhawulo ovaliwe lapho ivalvu ivaliwe, bese uhlola ukusebenza kokuvala kwepakethe kanye ne-gasket, futhi akufanele kube nokuvuza. Bese wethula indawo yokuhlola kusuka kolunye umkhawulo bese uphinda isivivinyo esingenhla.

(2)Ibhalansi elungisiweUkuhlolwa kokuqina kwe-valve l: ngaphambi kokuhlolwa, ibhola liphendulwa izikhathi eziningana ngaphandle komthwalo, bese i-valve yebhola ehleliwe isesimweni sokuvalwa, bese i-medium yokuhlola idonswa kusukela kolunye uhlangothi iye enanini elicacisiwe; I-pressure gauge isetshenziselwa ukuhlola ukusebenza kokuvala kwe-inlet end. Ukunemba kwe-pressure gauge kungu-0.5 ~ 1, kanti ububanzi bokulinganisa buyizikhathi ezingu-1.5 ze-test pressure. Ngesikhathi esicacisiwe, akukho mkhuba wokucindezeleka ofanelekile; Bese wethula i-test medium kusukela kolunye uhlangothi bese uphinda ukuhlolwa okungenhla. Bese, i-valve ivulekile ingxenye, zombili iziphetho zivaliwe, ingaphakathi ligcwele imidiya, futhi ukupakisha kanye ne-gasket kuhlolwa ngaphansi kwengcindezi yokuhlola ngaphandle kokuvuza.

(3)I-valve yebhola enezindlela ezintathu skufanele kuhlolwe ukuqina ezindaweni ezahlukene.

2.I-valve yokuhlolaindlela yokuhlola ingcindezi

Isimo sokuhlolwa kwevalvu yokuhlola: uhlobo lokuphakamisa i-axis yediski yokuhlola ivalvu isendaweni evundlile neqondile; I-axis yesiteshi sevalvu yokuhlola i-swing kanye ne-axis yediski cishe zihambisana nomugqa ovundlile.

Ngesikhathi sokuhlolwa kwamandla, indawo yokuhlola yethulwa enanini elicacisiwe kusukela ekugcineni kokungena, olunye uhlangothi luvaliwe, futhi umzimba wevalvu kanye nesembozo sevalvu kuyafaneleka ngaphandle kokuvuza.

Ukuhlolwa kokuvala kufanele kwethule indawo yokuhlola kusukela ekugcineni kokuphuma, kuhlolwe indawo yokuvala ekugcineni kokungena, bese ukupakisha kanye ne-gasket kufanele kuqinisekiswe uma kungekho ukuvuza.
