3. Ukunciphisa ingcindeziivalvuindlela yokuhlola ingcindezi

① Ukuhlolwa kwamandla kwevalvu yokunciphisa ingcindezi ngokuvamile kuhlanganiswa ngemva kokuhlolwa okukodwa, futhi kungahlanganiswa ngemva kokuhlolwa. Ubude bokuhlolwa kwamandla: 1 min nge-DN<50mm; DN65 ~ 150mm ubude kunemizuzu emi-2; Uma i-DN inkulu kune-150mm, idlula imizuzu emi-3. Ngemva kokuba izimbobo zihlanganiswe ezingxenyeni, ingcindezi ephezulu ephindwe ka-1.5 ngemva kokusetshenziswa kwevalvu yokunciphisa ingcindezi, bese ukuhlolwa kwamandla kwenziwa ngomoya.
② Ukuhlolwa kokuqina kwenziwa ngokwendlela yokusebenza yangempela. Uma kuhlolwa ngomoya noma ngamanzi, ukuhlolwa kwenziwa ngokuphindwe ka-1.1 kwengcindezi evamile; Uma kuhlolwa ngomusi, kwenziwa ngengcindezi yokusebenza ephezulu kakhulu evumelekile ekushiseni kokusebenza. Umehluko phakathi kwengcindezi yokungena kanye nengcindezi yokukhipha akufanele ube ngaphansi kuka-0.2MPa. Indlela yokuhlola imi kanje: ngemva kokulungiswa kwengcindezi yokungena, isikulufu sokulungisa sevalvu silungiswa kancane kancane ukuze ingcindezi yokukhipha ikwazi ukuguqulwa ngokuzwela nangokuqhubekayo ngaphakathi kobubanzi benani eliphakeme nelincane, ngaphandle kokuma nokuvaleka. Kwivalvu yokunciphisa ingcindezi yomusi, lapho ingcindezi yokungena isuswa, ivalvu ivaliwe bese ivalvu inqunywa, kanti ingcindezi yokukhipha iyinani eliphakeme neliphansi kakhulu. Phakathi nemizuzu emi-2, ukulinganiswa kwengcindezi yokukhipha kufanele kuhambisane nezinhlinzeko. Kumavalvu okunciphisa ingcindezi yamanzi nomoya, lapho ingcindezi yokungena ilungiswa kanye nengcindezi yokukhipha ingu-zero, ivalvu yokunciphisa ingcindezi ivaliwe ukuze kuvalwe, futhi akukho ukuvuza okungaphakathi kwemizuzu emi-2 okufanele.

4. I-valve yebhabhathaneindlela yokuhlola ingcindezi

Ukuhlolwa kwamandla evalvu yebhabhathane ephefumulayo kufana nokwevalvu yomhlaba. Ukuhlolwa kokusebenza kokuvala kwevalvu yebhabhathane kufanele kwethule indawo yokuhlola kusukela ekugcineni kokungena, ipuleti lebhabhathane kufanele livulwe, elinye icala kufanele livalwe, futhi ingcindezi yomjovo kufanele ifinyelele inani elibekiwe; Ngemva kokuhlola ukuthi akukho ukuvuza ephaketheni nakwezinye izivalo, vala ipuleti lebhabhathane, uvule elinye icala, bese uhlola ukuthi akukho ukuvuza ekuvalweni kwepuleti lebhabhathane. Amavalvu ebhabhathane asetshenziselwa ukulawula ukugeleza awenzi ukuhlolwa kokusebenza kokuvala.

5.I-plug valveindlela yokuhlola ingcindezi
①Uma ivalvu yepulaki ihlolwa amandla, i-medium ifakwa kusukela kolunye uhlangothi, ingxenye esele yendlela ivaliwe, bese ipulaki ijikeleziswa endaweni yokusebenza evulekile ngokuphelele ukuze ihlolwe, futhi umzimba wevalvu awutholakali uvuza.
② Ekuhlolweni kokuvala, i-cock eqondile kufanele igcine ingcindezi engaphakathi kwesikhala ilingana nephaseji, ijikelezise ipulaki iye endaweni evaliwe, ihlole kusukela kolunye uhlangothi, bese ijikelezisa ipulaki ngo-180° ukuze iphinde isivivinyo esingenhla; Ivalvu yepulaki enezindlela ezintathu noma ezine kufanele igcine ingcindezi engaphakathi kwesikhala ilingana nokuphela kokudlula, ijikelezise ipulaki iye endaweni evaliwe ngokulandelana, ingenise ingcindezi evela ekugcineni kwe-Angle kwesokudla, bese ihlola kolunye uhlangothi ngesikhathi esifanayo.
Ngaphambi kokuhlolwa kwevalvu yepulagi, kuvunyelwe ukufaka ungqimba lwamafutha okugcoba angena-asidi endaweni yokuvala, futhi akukho ukuvuza kanye namaconsi amanzi anwetshiwe atholakalayo ngaphakathi kwesikhathi esibekiwe. Isikhathi sokuhlolwa kwevalvu yepulagi singaba sifushane, ngokuvamile sinqunywa njengo-l ~ 3min ngokuya ngobubanzi obujwayelekile.
I-valve yepulagi yegesi kufanele ihlolwe ukuthi umoya uqinile kangakanani ngokuphindwe ka-1.25 kunengcindezi yokusebenza.

6.Ivalvu ye-diaphragmindlela yokuhlola ingcindezi

Ukuhlolwa kwamandla evalvu ye-diaphragm kwethula i-medium kusuka kunoma iyiphi ingxenye, kuvula idiski yevalvu, bese kuvala enye ingxenye. Ngemva kokuba ingcindezi yokuhlolwa ikhuphukele enanini elibekiwe, kuyafaneleka ukubona ukuthi umzimba wevalvu kanye nesembozo sevalvu akunawo ukuvuza. Bese wehlisa ingcindezi iye ekucindezelweni kokuhlolwa kokuqina, vala idiski yevalvu, uvule enye ingxenye ukuze kuhlolwe, akukho ukuvuza okufanelekile.

7.I-valve yokumisafuthiivalvu yokuphushaindlela yokuhlola ingcindezi
Ukuhlolwa kwamandla kwevalvu yomhlaba kanye nevalvu yokuphusha kuvame ukufakwa ivalvu ehlanganisiwe ku-rack yokuhlola ingcindezi, vula idiski yevalvu, ufake i-medium enanini elicacisiwe, bese uhlola ukuthi umzimba wevalvu kanye nesembozo sevalvu kuyajuluka futhi kuyavuza. Ukuhlolwa kwamandla nakho kungenziwa ngakunye. Ukuhlolwa kokuqina kwenzelwe ivalvu yokumisa kuphela. Ngesikhathi sokuhlolwa, isiqu sevalvu yokumisa sisesimweni esiqondile, idiski yevalvu iyavulwa, i-medium yethulwa kusukela ekugcineni kwediski yevalvu iye enanini elicacisiwe, bese kuhlolwa ukupakisha kanye ne-gasket. Uma kufanele, vala idiski yevalvu bese uvula olunye uhlangothi ukuze uhlole ukuthi kukhona yini ukuvuza. Uma kuzokwenziwa ukuhlolwa kwamandla kanye nokuqina kwevalvu, ukuhlolwa kwamandla kungenziwa kuqala, bese ingcindezi yehliswa iye enanini elicacisiwe lokuhlolwa kokuqina, bese kuhlolwa ukupakisha kanye ne-gasket. Bese uvala idiski yevalvu, vula ukuphela kokuphuma ukuze uhlole ukuthi ngabe ubuso bokuvala buyavuza yini.
