Ukusebenza okulungile kwe-valve yokuphepha
I-valve yokuphepha ihlolwe ingcindezi kanye nokucindezela okuqhubekayo ngaphambi kokufakwa. Uma i-valve yokuphepha isebenza isikhathi eside, opharetha kufanele anake ukuhlolwa kwevalvu yokuphepha. Ngesikhathi sokuhlola, opharetha kufanele agweme ukuphuma kwevalvu yokuphepha, ahlole uphawu lokuhola lwevalvu yokuphepha, adonse ivalve yokuphepha ngesikrufu ngesandla, futhi ayivule kanye ngesikhathi ukuze akhiphe ukungcola futhi ahlole. ukuguquguquka kwe-valve yokuphepha.
Indlela elungile yokusebenza ye-valve yokudonsa
I-valve yokukhipha amanzi kulula ukuvinjwa ukungcoliswa kwamanzi nezinye izinhlobo. Uma isetshenziswa, qala ngokuvula i-valve yokudonsa bese ukhipha ipayipi. Uma kukhona ipayipi le-bypass, i-valve ye-bypass ingavulelwa ukushaywa okufushane. Ukuze i-valve yokudonsa ngaphandle kwepayipi yokudonsa kanye nepayipi ye-bypass, i-valve yokudonsa ingasuswa. Ngemuva kokuvula i-valve yokuvala, vala i-valve yokuvala, faka i-valve yokudonsa, bese uvula i-valve yokuvala ukuze uvule i-valve yokudonsa.
Ukusebenza okulungile kwe-valve yokunciphisa ingcindezi
Ngaphambi kokuthi kuvulwe ivalvu yokwehlisa umfutho, ivalve yokudlula noma ivalve yokushaywa kufanele ivulwe ukuze kuhlanzwe ukungcola epayipini. Ngemuva kokuthi ipayipi selihlanziwe, i-valve yokudlula kanye ne-valve yokudonsa kuzovalwa, bese kuvulwa i-valve yokunciphisa ingcindezi. Amanye ama-valve okwehlisa umfutho we-steam anama-valve okukhipha amanzi phambi kwawo, okumele avulwe kuqala, bese evula kancane i-valve enqamukile ngemuva kwe-valve yokwehlisa umfutho, agcine evule i-valve enqamukile phambi kwe-valve yokwehlisa umfutho, iwashi. i-gauge yokucindezela ngaphambi nangemuva kwe-valve yokunciphisa ukucindezela, lungisa isikulufu esilawulayo se-valve yokunciphisa ingcindezi ukuze wenze ingcindezi engemuva kwe-valve ifinyelele inani elinqunyelwe kusengaphambili, bese uvula kancane kancane i-valve yokuvala ngemuva kwe-valve yokunciphisa ingcindezi, futhi ulungise ukucindezela ngemuva kwe-valve kuze kube yilapho usunelisekile. Lungisa isikulufu sokulungisa bese uvala ikepisi yokuvikela.
Uma i-valve yokunciphisa ukucindezela ihluleka noma idinga ukulungiswa, vula kancane kancane i-valve ye-bypass kuqala, vala i-valve yokuvala yangaphambili ngesikhathi esifanayo, cishe ulungise i-valve ye-bypass ngesandla, ukuze ingcindezi ngemuva kwe-valve yokunciphisa ingcindezi iqine ngokuyisisekelo. ngenani elisethiwe, bese uvala i-valve yokunciphisa ingcindezi ukuze ishintshwe noma ilungiswe, bese ibuyela kokujwayelekile.
Ukusebenza kahle kwe-valve yokuhlola
Ukuze ugweme amandla omthelela omkhulu ngesikhathi lapho i-valve yokuhlola ivaliwe, i-valve kufanele ivalwe ngokushesha ukuvimbela ukwakheka kwejubane elikhulu lokubuyela emuva, okuyisizathu sokwakheka kokucindezela komthelela lapho i-valve ivalwa ngokuzumayo. . Ngakho-ke, isivinini sokuvala se-valve kufanele sifaniswe ngendlela efanele nesivinini sokunciphisa se-medium downstream.
