3. Ukunciphisa ingcindezii-valveindlela yokuhlola ingcindezi

① Ukuhlolwa kwamandla kwe-valve yokunciphisa ingcindezi ngokuvamile kuhlanganiswa ngemva kokuhlolwa okukodwa, futhi kungahlanganiswa ngemva kokuhlolwa.Ubude besikhathi sokuhlolwa kwamandla: 1min nge-DN<50mm;I-DN65 ~ 150mm ubude kune-2min;Uma i-DN inkulu kuno-150mm, yinde kunemizuzu emi-3.Ngemuva kokuthi ama-bellows ashiselwe ezingxenyeni, izikhathi ezingu-1.5 zokucindezela okukhulu ngemuva kokusetshenziswa kwe-valve yokunciphisa ingcindezi, futhi ukuhlolwa kwamandla kwenziwa ngomoya.
② Ukuhlolwa kokuqina kwenziwa ngokuya ngendlela yokusebenza yangempela.Lapho kuhlolwa ngomoya noma ngamanzi, ukuhlolwa kwenziwa izikhathi ezingu-1.1 ukucindezela okuzisholo;Lapho kuhlolwa nge-steam, kwenziwa ngokucindezela okuphezulu okuvunyelwe ukusebenza ekushiseni okusebenzayo.Umehluko phakathi kwengcindezi yokungena kanye nengcindezi yokuphuma akufanele ibe ngaphansi kuka-0.2MPa.Indlela yokuhlola imi kanje: ngemva kokulungiswa kokucindezela kwe-inlet, isikulufu sokulungisa se-valve silungiswa kancane kancane ukuze ingcindezi yokuphuma ikwazi ukuzwela futhi ishintshwe ngokuqhubekayo ngaphakathi kwebanga lenani eliphakeme nelincane, ngaphandle kokuma nokuvinjwa.Ukuze i-valve yokunciphisa umfutho we-steam, lapho ukucindezela kwe-inlet kususwa, i-valve ivaliwe bese i-valve inqunywe, futhi ukucindezela kokuphuma kuyinani eliphakeme kakhulu neliphansi kakhulu.Phakathi nemizuzu emi-2, ukwazisa kokucindezela kokuphuma kufanele kuhambisane nezinhlinzeko.Kuma-valve okunciphisa umfutho wamanzi nomoya, lapho umfutho we-inlet ulungiswa futhi ingcindezi yokuphuma inguziro, i-valve yokunciphisa ingcindezi ivaliwe ukuze kuhlolwe ukuvala uphawu, futhi akukho ukuvuza kungakapheli imizuzu emi-2 okufanelekile.

4. Butterfly valveindlela yokuhlola ingcindezi

Ukuhlolwa kwamandla kwevalve uvemvane womoya kuyefana naleyo yevalvu yembulunga.Ukuhlolwa kokusebenza kokuvala i-valve ye-butterfly kufanele yethule indlela yokuhlola kusukela ekugcineni kokungena, ipuleti levemvane kufanele livulwe, elinye ukuphela kufanele livalwe, futhi ukucindezela komjovo kufanele kufinyelele inani elishiwo;Ngemva kokuhlola ukuthi akukho ukuvuza ekupakisheni nakwezinye izimpawu, vala ipuleti levemvane, uvule ngakolunye uhlangothi, futhi uhlole ukuthi akukho yini ukuvuza ku-butterfly plate seal.Amavalvu ovemvane asetshenziselwa ukulawula ukugeleza awenzi ukuhlolwa kokusebenza kokuvala uphawu.

5.I-valve yokuxhumaindlela yokuhlola ingcindezi
①Uma i-valve yepulaki ihlolelwa amandla, okuphakathi kwethulwa ukusuka ekugcineni, enye indlela iyavalwa, futhi ipulaki lizungeziswa liyiswe endaweni yokusebenza evuleke ngokugcwele ukuze lihlolwe, futhi umzimba wevalvu awutholakali uvuza.
② Esivivinyweni sokuvala, iqhude eliqondile kufanele ligcine ukucindezela emgodini olingana nephaseji, ukushintshanisa ipulaki endaweni evaliwe, hlola ukusuka komunye umkhawulo, bese uzungezisa ipulaki 180 ° ukuze uphinde ukuhlolwa okungenhla;I-valve yepulaki yezindlela ezintathu noma ezine kufanele igcine ingcindezi emgodini ilingana nomkhawulo owodwa wephaseji, ijikelezise ipulaki endaweni evaliwe, yethule ukucindezela okuvela ekugcineni kwe-Engeli engakwesokudla, futhi ihlole enye ekugcineni ngesikhathi esifanayo.
Ngaphambi kokuhlolwa kwe-valve yepulaki, kuvunyelwe ukusebenzisa ungqimba lwamafutha okugcoba ancibilikisiwe angena-acidic endaweni yokuvala, futhi akukho ukuvuza namaconsi amanzi anwetshiwe atholakala phakathi nesikhathi esibekiwe.Isikhathi sokuhlola se-valve yepulaki singaba sifushane, ngokuvamile sibekwe ngokuthi l ~ 3min ngokuya ngobubanzi obujwayelekile.
I-valve yepulaki yegesi kufanele ihlolwe ukuqina komoya izikhathi ezingu-1.25 zokucindezela kokusebenza.

6.I-valve ye-diaphragmindlela yokuhlola ingcindezi

Ukuhlolwa kwamandla e-valve ye-diaphragm kwethula okuphakathi kusuka kunoma yimuphi umkhawulo, kuvula idiski ye-valve, futhi ivale enye indawo.Ngemuva kokuthi ingcindezi yokuhlola ikhuphukele enanini elishiwo, iyafaneleka ukubona ukuthi umzimba we-valve nesembozo se-valve akukho ukuvuza.Bese wehlisa ingcindezi ku-tightness test pressure, vala i-valve disc, uvule omunye umkhawulo ukuze uhlolwe, akukho ukuvuza okufanelekile.

7.Misa i-valvefuthii-throttle valveindlela yokuhlola ingcindezi
Ukuhlolwa kwamandla e-valve yembulunga kanye ne-throttle valve kuvame ukufaka i-valve ehlanganisiwe endaweni yokuhlola ingcindezi, uvule idiski ye-valve, ujove okuphakathi nenani elishiwo, futhi uhlole ukuthi umzimba we-valve nesembozo se-valve ziyajuluka futhi ziyavuza.Ukuhlolwa kwamandla nakho kungenziwa ngakunye.Ukuhlolwa kokuqina okwe-valve yokumisa kuphela.Ngesikhathi sokuhlolwa, isiqu se-valve yokumisa sisesimweni esiqondile, i-disc ye-valve ivuliwe, i-medium yethulwa kusukela ekugcineni kwe-disc ye-valve kuya enani elicacisiwe, futhi ukupakisha kanye ne-gasket kuyahlolwa.Uma usufanelekile, vala idiski ye-valve bese uvula enye indawo ukuze uhlole ukuthi akukho yini ukuvuza.Uma ukuhlolwa kokuqina kwe-valve nokuqina kufanele kwenziwe, ukuhlolwa kwamandla kungenziwa kuqala, bese ukucindezela kuncishiswa kunani elicacisiwe lokuhlolwa kokuqina, futhi ukupakisha kanye ne-gasket kuyahlolwa.Bese uvala i-disc ye-valve, vula i-outlet ukuze uhlole ukuthi ukuvuza kwendawo yokuvala uphawu.
