Qinisekisa ukuba umbhobho kwindawo yofakelo lweivalve yebholaikwindawo yecoaxial, kwaye iiflange ezimbini kumbhobho kufuneka zigcinwe zidityanisiwe ukuqinisekisa ukuba umbhobho ungathwala ubunzima bevalve yebhola ngokwayo.Ukuba kufunyaniswe ukuba umbhobho awukwazi ukuthwala ubunzima bevalve yebhola, nikezela ngenkxaso ehambelanayo yombhobho ngaphambi kofakelo.
1. Qinisekisa ukulungiswa kwevalve yebhola ngaphambi kokufakwa
1. Qinisekisa ukuba umbhobho okwindawo yofakelo lwevalve yebhola ikwimo ecoaxial, kwaye iiflange ezimbini kumbhobho kufuneka zigcinwe ngaxeshanye ukuqinisekisa ukuba umbhobho ungathwala ubunzima bevalve yebhola ngokwayo.Ukuba kufunyaniswe ukuba umbhobho awukwazi ukuthwala ubunzima bevalve yebhola, nikezela ngenkxaso ehambelanayo yombhobho ngaphambi kofakelo.
2. Qinisekisa ukuba kukho ukungcola, i-welding slag, njl njl kwipayipi, kwaye umbhobho kufuneka uhlambuluke.
3. Khangela i-nameplate yevalve yebhola, kwaye wenze imisebenzi yokuvula ngokupheleleyo kunye nokuvala ngokupheleleyo kwivalve yebhola amaxesha amaninzi ukuqinisekisa ukuba ivalve inokusebenza ngokuqhelekileyo, kwaye emva koko uhlolisise iinkcukacha zevalve ukuqinisekisa ukuba isivalo silungile. yomelele.
4. Susa isigqubuthelo esikhuselayo kuzo zombini iziphelo zevalvu, khangela ukuba umzimba wevalvu ucocekile, kwaye ucoce umngxuma womzimba wevalvu.Kuba umphezulu wokutywina wevalve yebhola ungqukuva, kwanobutyobo obuncinci bunokubangela umonakalo kumphezulu wokutywina.
2. Ukufakwa kwevalve yebhola
1. Naliphi na icandelo levalve yebhola linokufakwa ekupheleni komlambo, kunye nevalve yokubamba ibhola inokufakwa kuyo nayiphi na indawo kumbhobho.Ukuba ivalve yebhola ene-actuator (efana nebhokisi yegiya, i-electro-pneumatic actuator) icwangcisiwe, kufuneka ifakwe ngokuthe nkqo, kwindawo yokungena kunye nokuphuma kwevalve.kwindawo ethe tye.
2. Faka i-gasket phakathi kweflange yevalve yebhola kunye neflange yombhobho ngokweemfuno zoyilo lombhobho.
3. Iibholiti kwi-flange kufuneka ziqiniswe ngokulinganayo, ngokulandelelana kunye nokulinganisa.
4. Ukuba i-valve yebhola ithatha i-pneumatic, umbane kunye nezinye i-actuator, gcwalisa ukufakwa komthombo womoya kunye nokunikezelwa kwamandla ngokwemiyalelo.
3. Ukuhlolwa emva kokufakwa kwevalve yebhola
1. Emva kokufakela, qalisa ivalve yebhola ukuvula nokuvala amaxesha amaninzi.Kufuneka iguquguquke kwaye ifane, kwaye ivalve yebhola kufuneka isebenze ngokuqhelekileyo.
2. Ngokweemfuno zoyilo loxinzelelo lombhobho, jonga ukusebenza kokutywinwa kwendawo edibeneyo phakathi kwevalve yebhola kunye ne-pipeline flange emva kokusetyenziswa koxinzelelo.
Okwesine, ukugcinwa kwevalve yebhola
1. Ivalve yebhola inokuchithwa kwaye ihlulwe kuphela emva koxinzelelo ngaphambi nangemva kokuba ivalve yebhola isusiwe.
2. Kwinkqubo yokuqhawula kunye nokuphinda kuhlanganiswe i-valve yebhola, kuyimfuneko ukukhusela iindawo zokutywinwa, ngakumbi iindawo ezingezizo zetsimbi.Kungcono ukusebenzisa izixhobo ezikhethekileyo kwiindawo ezifana ne-O-rings.
3. Xa umzimba wevalve yebhola udityaniswa kwakhona, iibholithi kufuneka ziqiniswe ngokulinganayo, ngokuthe ngcembe kwaye ngokulinganayo.
4. I-arhente yokucoca kufuneka ihambelane neendawo zerabha, iiplastiki, iindawo zetsimbi kunye nendawo yokusebenza (njengegesi) kwi-valve yebhola.Xa i-medium yokusebenza igesi, i-petroli (GB484-89) ingasetyenziselwa ukucoca iindawo zetsimbi.Coca iindawo ezingezizo ezentsimbi ngamanzi acocekileyo okanye utywala.
5. Inxalenye enye ebolileyo inokucocwa ngokuditshwa.Iingxenye zetsimbi ezineengxenye ezingezizo zetsimbi ezingaboliyo zinokuhlanjululwa ngepompo eyomileyo ye-rotor ngelaphu elicolekileyo nelicocekileyo elifakwe kwi-agent yokucoca (ukuthintela imicu ukuba ingawi kwaye ibambelele kwiindawo).Xa ucoca, yonke igrisi, ukungcola, iglue, uthuli, njl njl ukunamathela eludongeni kufuneka kususwe.
6. Iindawo ezingezizo zetsimbi kufuneka zisuswe kwi-ejenti yokucoca ngokukhawuleza emva kokucoca, kwaye akufanele zifakwe ixesha elide.
7. Emva kokucoca, kufuneka ihlanganiswe emva kokuba i-agent yokucoca eludongeni ihlanjwe iguquguquke (inokusulwa ngendwangu yesilika engazange ifakwe kwi-agent yokucoca), kodwa akufanele ibekwe. ixesha elide, kungenjalo iya kugqwala kwaye ingcoliswe luthuli.
8. Kwakhona amalungu amatsha kufuneka acocwe ngaphambi kokuba adibane.
9. Lubricate ngegrisi.Igrisi kufuneka ihambelane nezixhobo zentsimbi yevalve yebhola, iinxalenye zerabha, iinxalenye zeplastiki kunye nendawo yokusebenza.Xa indawo yokusebenza iyigesi, igrisi ingasetyenziswa.Faka umaleko obhityileyo wegrisi kumphezulu wegroove yokufaka itywina, sebenzisa umaleko obhityileyo wegrisi kwitywina lerabha, kwaye usebenzise umaleko obhityileyo wegrisi kumphezulu wokutywina kunye nomphezulu wokukhuhlana kwesiqu sevalve.
10. Iichips zetsimbi, iifibers, igrisi (ngaphandle kwezo zichazwe ukuba zisetyenziswe), uthuli kunye nezinye izinto ezingcolileyo, izinto zangaphandle akufanele zivunyelwe ukungcolisa, ukunamathela okanye ukuhlala phezu kwendawo okanye ukungena kwi-cavity yangaphakathi ngexesha lokudibanisa.
