Umsebenzi Intshayelelo
Ucikizeko oluzenzekelayo ukuvala
Xa isilawuli soxinzelelo kwisiphelo sangaphambili sombhobho werhasi sisebenza ngokungaqhelekanga okanye uxinzelelo lwemibhobho luphezulu kakhulu ngenxa yovavanyo loxinzelelo lombhobho olwenziwa yinkampani yerhasi, kwaye lugqithise ixabiso lokumisela umbhobho wegesi wokuzivala ngokwawo, ivalve. iya kuvala ngokuzenzekelayo ngenxa yoxinzelelo olugqithisileyo ukuthintela uxinzelelo olubangelwa luxinzelelo lombhobho. Ukuphakama ngokugqithisileyo kunye nokuvuza kwegesi kwenzeka.
Ukucima okuzenzekelayo phantsi koxinzelelo
Xa isilawuli soxinzelelo kwisiphelo esingaphambili sombhobho werhasi singaqhelekanga, ngexesha lencopho yokusetyenziswa kwerhasi, umbhobho werhasi uyakhenkceka kwaye uvalwe, ukunqongophala kwerhasi ebusika, ukuvalwa kwerhasi, ukutshintshwa, ukunyibilika kunye neminye imisebenzi ibangela uxinzelelo lwemibhobho ukuba yehla kwaye iwe phantsi kwexabiso elimiselweyo, I-valve iya kuvala ngokuzenzekelayo phantsi koxinzelelo lokuthintela iingozi zokuvuza kwegesi ezinokuthi zenzeke xa uxinzelelo lomoya lubuyiselwa.
Ukuphuphuma kokucima okuzenzekelayo
Xa ukutshintshwa komthombo wegesi kunye nesilawuli soxinzelelo sangaphambili-sokugqibela sombhobho wegesi singaqhelekanga, okanye i-hose yerabha iyawa, ubudala, ukugqabhuka, umbhobho we-aluminium-plastiki kunye nombhobho wesinyithi utyhulwa ngumhlwa wombane, iintanda zivela kwiinguqu zoxinzelelo, uxhulumaniso lukhululekile, kwaye isitovu segesi asiqhelekanga, njl.n unikezelo lwerhasi, kunye nokuthintela iingozi zokhuseleko ezinokubakho ezibangelwa kukuphuma kwerhasi ngokugqithisileyo.
Umyalelo wokusetyenziswa
Ivalve yokuqala ikwimeko evaliweyo
imeko yokusebenza eqhelekileyo
I-Undervoltage okanye i-overcurrent self-shutdown
overpressure self- shutdown
1. Kwimeko yokunikezelwa komoya oqhelekileyo, phakamisa ngobumnene iqhosha lokuphakamisa i-valve (vele uyiphakamise ngobumnene, ungasebenzisi amandla amaninzi), i-valve iya kuvula, kwaye iqhosha lokuphakamisa liza kusetha ngokuzenzekelayo emva kokuyikhulula. Ukuba iqhosha lokuphakamisa alikwazi ukusetwa kwakhona ngokuzenzekelayo, nceda ucinezele ngesandla iqhosha lokuphakamisa ukulimisela kwakhona.
2. Isimo esiqhelekileyo sokusebenza kwevalve siboniswe kumzobo. Ukuba kuyimfuneko ukuphazamisa ukunikezelwa kwegesi kwisixhobo segesi ngexesha lokusetyenziswa, kuyimfuneko kuphela ukuvala i-valve manual ekupheleni kwe-valve. Akuvunyelwe ngokungqongqo ukucinezela imodyuli yesalathisi ngesandla ukuvala ngqo i-valve.
3. Ukuba imodyuli yesalathisi ihla kwaye ivale i-valve ngexesha lokusetyenziswa, ithetha ukuba i-valve ingene kwi-undervoltage okanye i-overcurrent self-closing state (njengoko kuboniswe kumfanekiso). Abasebenzisi banokuzijonga ngezi zizathu zilandelayo. Kwiingxaki ezingenako ukusonjululwa ngokwazo, kufuneka zisonjululwe yinkampani yegesi. Sukuyicombulula ngokwakho, izizathu ezinokwenzeka zezi zilandelayo:
(1) Unikezelo lwerhasi luphazamisekile okanye uxinzelelo lombhobho luphantsi kakhulu;
(2) Inkampani yegesi iyayeka igesi ngenxa yokugcinwa kwezixhobo;
(3) Imibhobho yangaphandle yonakaliswa ziintlekele zendalo ezenziwe ngabantu;
(4) Abanye kwigumbi Ivalve yokuvala ngexesha likaxakeka ivalwe ngenxa yeemeko ezingaqhelekanga;
(5) Umbhobho werabha uyawa okanye isixhobo serhasi asiqhelekanga (njengokuvuza kwerhasi okubangelwa sisitshi esingaqhelekanga);
4. Ngethuba lokusetyenziswa, ukuba imodyuli yesalathisi ifunyenwe ukuba iphakame kwindawo ephezulu, ithetha ukuba i-valve ikwimeko yokuzivala ngokugqithisileyo (njengoko kuboniswe kumfanekiso). Abasebenzisi banokwenza ukuzihlola ngokusebenzisa ezi zizathu zilandelayo kwaye bazisombulule ngenkampani yegesi. Musa ukuyisombulula wedwa. Emva kokusombulula ingxaki, cinezela imodyuli yesalathisi ukubuyisela i-valve kwindawo yokuqala evaliweyo, kwaye uphakamise iqhosha lokuphakamisa i-valve kwakhona ukuze uvule i-valve. Izinto ezinokubangela uxinezeleko olugqithisileyo ziquka ezi zilandelayo:
(1) Isilawuli soxinzelelo olungaphambili kumbhobho werhasi asisebenzi kakuhle;
(2) Inkampani yegesi iqhuba imisebenzi yombhobho. Uxinzelelo olugqithisileyo lombhobho ngenxa yovavanyo loxinzelelo;
5. Ngethuba lokusetyenziswa, ukuba uchukumisa ngengozi imodyuli yesalathisi, ebangela ukuba i-valve ivale, kufuneka uphakamise iqhosha ukuze uvule kwakhona i-valve.
