Ngaphambi kokuthi i-valve ifakiwe, ukuhlolwa kwamandla we-valve kanye nokuhlolwa kokubekwa uphawu kwe-valve kufanele kwenziwe ebhentshini lokuhlola le-hydra. Ama-20% ama-valves aphansi aphansi kufanele ahlolwe ngokungahleliwe, futhi ama-100% kufanele ahlolwe uma engafaneleki; I-100% yama-valves aphakathi nendawo aphezulu ahlolwe. Imidiya esetshenziswa kakhulu yokuhlolwa kwengcindezi ye-valve ingamanzi, uwoyela, umoya, umusi, i-nitrogen, njll. Izindlela zokuhlola ingcindezi zezimboni zifaka ama-pneumatic valves anjengokulandelayo:
Indlela yokuhlola ingcindezi ye-Butterfly Valve
Ukuhlolwa kwamandla kwe-pneumatic butterfly valve kuyafana nalokho kwe-valve ye-hlaba. Ekuhlolweni kokusebenza kokubekwa uphawu kwe-valve yevemvane, i-test medium kufanele yethulwe ngokuphela kokugeleza kwaphakathi nendawo, kufanele ivulwe ipuleti levemvane, elinye ukuphela kufanele livalwe, futhi ingcindezi yomjovo kufanele ivalwe ngenani elishiwoyo; Ngemuva kokubheka ukuthi akukho ukuvuvukala kokupakisha nezinye izimpawu, vala ipuleti levemvane, vula elinye ukuphela, bese uhlola i-valve ye-butterfly. Akukho ukuvuza epulazilweni sepuleti okufanelekile. I-Butterfly Valve esetshenziselwa ukulawula ukugeleza kungenzeka ingahloliswa ukusebenza kokubekwa uphawu.
Indlela yokuhlola ingcindezi yokuhlola i-valve
Bheka isimo sokuhlola i-valve I-axis yesiteshi se-Swing Check valve ne-axis disc isesikhundleni esilingana nomugqa ovundlile.
Ngesikhathi sokuhlolwa kwamandla, i-Test Medium yethulwa kusuka ku-Inlet kuya kunani elicacisiwe, kanti elinye ukuphela kuvaliwe, futhi kuyakufaneleka ukubona ukuthi umzimba we-valve nesembozo se-valve asinawo ukuvuza.
Esivivinyweni sokubopha uphawu, i-Test Medium yethulwa kusuka ekugcineni kokuphuma, futhi indawo ebekelwe uphawu ihlolwe endaweni yokungena, futhi akukho ukuvuvukala kokupakisha kanye ne-gasket kuqeqeshiwe.
Indlela yokuhlola ingcindezi ye-valve valve
Ukuhlolwa kwamandla kwe-valuy valve kuyafana nalokho kwe-valve ye-hlaba. Kunezindlela ezimbili zokuhlolwa kokuqina kwe-valuav valve.
①Vula isango ukwenza ingcindezi e-valve kukhuphuke inani elishiwo; Bese uvale isango, ukhiphe i-valuach valve ngokushesha, hlola ukuthi kukhona ukuvuza ezinhlakeni zombili zesango, noma ngokuqondile kufakwa okuphakathi kokuhlolwa ku-plug kwinani elishiwo, hlola izimpawu ezinhlangothini zombili zesango. Indlela engenhla ibizwa ngokuthi ukuhlolwa kwengcindezi ephakathi. Le ndlela akufanele isetshenziselwe ukuhlolwa kokuvalwa kwamakhasi kuma-valog valves nge ububanzi obusezingeni eliphansi ngaphansi kwe-DN32mm.
②Enye indlela ukuvula isango ukwenza ingcindezi yokuhlolwa kwe-valve kukhuphuke inani elithile; Bese uvale isango, vula umkhawulo owodwa wepuleti elingaboni, bese ubheka ukuthi ingabe indawo ebopha uphawu iyavuza. Bese ubuyela emuva uphinde uphinde uhlole ukuhlolwa okungenhla aze afaneleke.
Ukuhlolwa kokuqina kokupakisha kanye ne-gasket ye-pneumatic gate valve kuzokwenziwa ngaphambi kokuhlolwa kwesango.
Indlela yokuhlola ingcindezi yokucindezela ukunciphisa i-valve
①Ukuhlolwa kwamandla kokucindezela okunciphisa i-valve kuvame ukuqoswa kuqoqwe ngemuva kokuhlolwa okukodwa, futhi kungahlolwa ngemuva komhlangano. Isikhathi sokuhlolwa kwamandla: 1min ye-DN <50mm; ngaphezu kwe-2min ye-DN65~I-150mm; Ngaphezu kwe-3min ye-DN> 150mm.
Ngemuva kokuthi ama-bellets kanye nezakhi kufakwa izinsimbi, zisebenzisa izikhathi eziyi-1.5 zokucindezela okukhulu kwengcindezi enciphisa i-valve, bese wenza ukuhlolwa kwamandla ngomoya.
②Ukuhlolwa komoya kuzokwenziwa ngokuya nge-medium medium yangempela. Lapho uhlolelwa ngomoya noma emanzini, avivinya ngezikhathi eziyi-1.1 ukucindezela okushiwo; Lapho uhlolelwa umusi, sebenzisa ingcindezi yokusebenza ephezulu evunyelwe ngaphansi kokushisa okusebenzayo. Umehluko phakathi kwengcindezi ye-inlet kanye nengcindezi yokuphuma kudingeka ungabi ngaphansi kuka-0.2MPA. Indlela yokuhlola yilena: Ngemuva kokushintshwa kwengcindezi ye-inlet, kancane kancane lungisa isikulufu sokulungisa i-valve, ukuze umcindezeli we-outlet ushintshe ngokuzwakalayo futhi ngokuqhubekayo uhla lwamanani aphezulu futhi aphansi, ngaphandle kokugwazwa noma ama-jamming. Ngokucindezela kwengcindezi evuthayo, lapho ingcindezi yokungena ilungiswa kude, i-valve ivaliwe ngemuva kokuthi i-valve ivaliwe, futhi ingcindezi yokuphuma ingamanani aphezulu kakhulu futhi aphansi. Ngaphakathi kwe-2min, ukukhuphuka kwengcindezi yokuphuma kufanele kuhlangabezane nezidingo eziseThebo 4.176-22. Ngasikhathi sinye, ipayipi ngemuva kwe-valve kufanele kube yivolumu livumelanisa nezidingo eziseThebo 4.18 ukuze zifaneleke; Ngamanzi kanye nengcindezi yomoya enciphisa ama-valves, lapho kufakwa ingcindezi ye-inlet kanye nengcindezi yokuphuma kungu-zero, ukuncipha kwengcindezelo kuvaliwe ukulolonga lokuqina, futhi akukho ukuvuza kungakapheli imizuzu emi-2.
Indlela yokuhlola ingcindezi yeGlobe Valve ne-Throttle valve
Ukuze uthole ukuhlolwa kwamandla kwe-valve ye-gener valve kanye ne-throttle valve, i-valve eqoqekile ivame ukubekwa efreyimu yokuhlola ingcindezi, i-valve disc ivuliwe, nomzimba we-valve kanye nesembozo se-valve kubhekwe ukujuluka nokuvuza. Ukuhlolwa kwamandla nakho kungenziwa eqenjini elilodwa. Ukuhlolwa kokuqina kwe-valve evaliwe kuphela. Ngesikhathi sokuhlolwa, isiqu se-valve ye-valve ye-globalve sisesimweni esithe mpo, i-valve disc ivuliwe, i-medium yethulwa kusuka emaphethelweni aphansi we-valve disc kunani elicacisiwe, futhi ukupakisha kanye ne-gasket kuhloliwe; Ngemuva kokudlula esivivinyweni, i-valve disc ivaliwe, kanti enye ukuphela kuvulwa ukubheka ukuthi ngabe kukhona ukuvuza. Uma ukuhlolwa kanye nokuhlolwa kwe-valve kufanele kwenziwe, ukuhlolwa kwamandla kungenziwa kuqala, khona-ke ingcindezi incishiswa ibe yinani elishiwolo lokuhlolwa kokuqina, kanye nokupakisha kanye ne-gasket kuhloliwe; Lapho-ke i-valve disc ivaliwe, futhi okuphumayo kuvulwa ukubheka ukuthi ngabe indawo yokubopha iyavuza yini.
Indlela yokuhlola ingcindezi ye-Ball Valve
Ukuhlolwa kwamandla kwe-pneumatic ibhola valve kufanele kwenziwe ngesimo esivulekile se-valve yebhola.
①Ukuhlolwa kwebhola lebhola elintantayo Jikelezisa ibhola izikhathi eziningana, vula isiphelo esivaliwe lapho i-valve isesimweni esivaliwe, bese uhlola ukusebenza kokubekwa uphawu epaki nase-gasket ngasikhathi sinye. Akufanele kube khona ukuvuza. Umphakathi wokuhlola ubese wethulwa ngakolunye uhlangothi futhi ukuhlolwa okungenhla kuyaphindwa.
②Ukuvivinywa kokubekwa uphawu kwe-valve yebhola elimisiwe Ukusebenza kokubekwa uphawu kwesingeniso sesingeniso kuhlolwe ngegeji yengcindezi, futhi ukunemba kwegeji kungu-0 .5 kuya ku-1, ibanga kungu-1.6 izikhathi zokuhlola. Ngaphakathi kwesikhathi esibekiwe, uma kungekho nto yokucindezelwa, iyafaneleka; Bese wethula okuphakathi kokuhlola kusuka komunye umkhawulo, bese uphinda isivivinyo esingenhla. Ngemuva kwalokho, beka i-valve ngesimo esivulekile, uvale zombili iziphetho, bese ugcwalisa umgodi wangaphakathi nge-medium. Bheka ukupakisha kanye ne-gasket ngaphansi kwengcindezi yokuhlola, futhi akumele kube khona ukuvuza.
③I-valve ye-bhola yendlela emithathu izohlolwa ngokuqina endaweni ngayinye.
