Yini okufanele inakwe lapho ususa i-flange noma ukukhishwa kwe-valve

Ukuchithwa kwe-flange noma i-valve drainage kungomsebenzi ojwayelekile wamabhizinisi amakhemikhali. Ngaphambi kokuthi sisebenze, kufanele siqonde ukuthi yiziphi izingozi ezifihliwe ezikhona kulo msebenzi:
Fafaza uketshezi noma igesi, zishise wena noma ozakwenu
Izinto ezinzima ziyawa futhi zilimaze
Izithiyo ezizungezile zilimele
(Kudingeka siqonde ukuthi noma iyiphi ingozi engavinjelwa ingaholela kunoma iyiphi ingozi engase ibe yingozi enkulu, futhi lezi zingozi ezintathu ezilula zitholakala ekuphileni kwansuku zonke.
Kudingeka sithathe izinyathelo ezisebenzayo ngokumelene nezingozi ezifihliwe esizilindele:
Lapho sisusa i-flange, kungakhathaliseki ukuthi kukhona okuphakathi kuyo, kufanele siqale kusukela ohlangothini lwethu oluphambene ukuze sisuse i-flange, siqinisekise ukuthi abekho abanye ozakwethu noma imishini kagesi ekuvuleni kwe-flange; Abantu ababili kumele baqinisekise ukuthi i-flange ye-*** yokuvula akuzona izisebenzi; Lapho ukhipha i-valve, qiniseka ukuthi akukho muntu ekuvuleni kwe-valve
Lapho usebenza, kufanele ugqoke isembozo sokuzivikela, ungalokothi ugqoke i-cha noma ufake izibuko kuphela
Ngaphambi komsebenzi, sidinga ukujwayela indawo yokusebenza ukuze sigweme ukushayisana nezithiyo ezisizungezile ngenxa yokwethuka ohlelweni lokusebenza. Ngaphezu kwalokho, lapho singena endaweni yokusebenza, kufanele sigqoke isigqoko sokuphepha, futhi sigweme ukungagqoki noma ukugqoka okungajwayelekile.
Lapho ungena endaweni yokusebenza, kufanele ugqoke izicathulo ezivimbela ukuphahlazeka ukuze ugweme ukuwa kwama-flange noma ontanga bawa phansi futhi balimala ngesikhathi sokuhlinza.
Ithuluzi lokuvala uphawu lwe-nitrogen lakhiwe izingxenye ezintathu: i-valve yokuhlinzeka nge-nitrogen, i-nitrogen discharge valve kanye nevalve yokuphefumula. I-valve yokuhlinzeka nge-nitrogen yakhiwe izingxenye ezimbili: i-conductor ne-valve eyinhloko. I-valve yokukhulula i-nitrogen yakhiwe isilawuli sokucindezela i-micro-pressure esivulekile esinempendulo yangaphakathi. Umfutho we-nitrogen ngokuvamile usethelwa ku-100mmH2O, olawulwa idivayisi yokuvala i-nitrogen.
Isimiso se-Nitrogen seal valve: lapho ithangi elingene kuvalvu ewuketshezi livuleka, engeza okokusebenza ethangini, ukukhuphuka kwezinga loketshezi, ivolumu yengxenye yegesi iyehla, futhi umfutho uyanda, lapho umfutho wethangi ungaphezu kokukhipha kwawo i-nitrogen valve pressure, ukukhishwa kwe-nitrogen. i-valve ukuze ivuleke, ikhiphe i-nitrogen emhlabeni futhi yenza umfutho wethangi wehle, yehle ukuze ikhiphe i-valve ye-nitrogen pressure set point, ivale ngokuzenzakalelayo.
Lapho i-valve ye-liquid outlet ye-tank yokugcina ivuliwe futhi impahla ikhishwa, izinga le-liquid liyehla, umthamo wesigaba segesi uyanda, futhi ukucindezela ku-tank kuyancipha. Ivalvu yokunikezela nge-nitrogen iyavulwa bese i-nitrogen ijovwa ethangini lokugcina, ukuze umfutho osethangini ukhuphuke ufike endaweni emisiwe yokucindezela kwevalvu yokuphakela i-nitrogen futhi ivaleke ngokuzenzakalelayo.
Imikhiqizo yethu eyinhloko i-valve yokunciphisa ingcindezi ezisebenza ngokwayo, idivayisi yokuvala i-nitrogen, i-valve yokuvala i-nitrogen, i-valve yokulawula isihlalo esisodwa kagesi, i-pneumatic film control valve nokunye. Siyakwamukela ukushayela umugqa wesevisi yenkampani ngekhasi lewebhu ukuze ufunde imininingwane eyengeziwe yomkhiqizo, okungcono kakhulu kwinkonzo yase-United States ukuphishekela kwethu okungapheli, sicela uqiniseke ukuthi uthenge imikhiqizo abayithandayo, sizokukhonza ngenhliziyo yonke!
