Ngokukhula kwejubane lokuthuthukiswa kwezimboni, ama-valve anengcindezi ephansi asetshenziswa kabanzi ezimbonini eziningi. Njengengxenye eyinhloko ohlelweni lokudlulisa uketshezi, i-valve yokucindezela okuphansi idlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile nokuzinzile kwesistimu. Kodwa-ke, lapho kubhekene nenqwaba yemikhiqizo ye-valve yengcindezi ephansi emakethe, indlela yokwenza ukukhetha okuhlakaniphile sekugxilwe kubasebenzisi abaningi. Lesi sihloko sizohlaziya izici ezithinta intengo yama-valve anengcindezi ephansi e-China kuwe, futhi sinikeze iziphakamiso zokuthenga ezizokusiza ukuthi uthenge ama-valve anengcindezi ephansi ngokusebenza kwezindleko eziphezulu.
Okokuqala, izici zentengo ye-valve yengcindezi ephansi yaseChina
1. Ibhrendi nekhwalithi
Ibhrendi nekhwalithi yizici ezibalulekile ezithinta intengo yeama-valve anengcindezi ephansi e-China . Ikhwalithi ephezulu ye-valve ye-low-pressure, ikhwalithi yomkhiqizo wayo, ukusebenza nokuzinza kungcono, ngakho intengo iphakeme kakhulu. Ngokuphambene nalokho, uhlobo olujwayelekile lwama-valve anengcindezi ephansi, ngenxa yokuhluka kwekhwalithi nokusebenza, intengo izoba ngaphansi.
2. Indaba
Izinto ze-valve yokucindezela okuphansi zithinta ngqo impilo yayo yenkonzo nokusebenza kwayo. Izinto ezihlukene zama-valve okucindezela okuphansi, intengo izohluka. Isibonelo, ama-valve ensimbi engagqwali aphansi ngenxa yokumelana nokugqwala okuhle, impilo ende yenkonzo, intengo iphakeme kakhulu.
3. Imininingwane namamodeli
Ukucaciswa kanye namamodeli ama-valve okucindezela okuphansi nakho kuyizici ezibalulekile ezithinta intengo. Ukucaciswa okuhlukene kanye namamodeli ama-valve anengcindezi ephansi, izindleko zabo zokukhiqiza nokusebenza kuhlukile, ngakho intengo izohluka. Khetha ukucaciswa okufanele namamodeli ngokuya ngezidingo zangempela.
4. Ubudlelwano bokuhlinzekwa kwemakethe kanye nesidingo
Ubudlelwano bokuhlinzekwa kwemakethe kanye nesidingo bunomthelela othile enanini lamavalvu omfutho ophansi e-China. Lapho isidingo semakethe siphezulu, intengo ingase ikhuphuke kancane; Isidingo semakethe sincane, futhi intengo ingase ibe phansi uma kuqhathaniswa.
Okwesibili, iseluleko sokuthenga
1. Khetha uhlobo olufanele nemodeli ngokwesidingo sangempela
Ekuthengweni kweama-valve anengcindezi ephansi , kufanele kuhlanganiswe nezidingo zangempela zokusetshenziswa, khetha umkhiqizo owaziwayo onekhwalithi enhle nokuzinza. Ngesikhathi esifanayo, imodeli efanele kanye nokucaciswa kufanele kukhethwe ukuhlangabezana nezidingo ezithile zesistimu.
2. Naka izinto ezibonakalayo, naka ukusebenza kwezindleko
Uma sithenga ama-valve anengcindezi ephansi, kufanele sinake umthelela wezinto ezibonakalayo ekusebenzeni komkhiqizo nempilo. Ngesikhathi esifanayo, ngaphansi kwesisekelo sokuhlangabezana nezidingo zokusetshenziswa, kufanele sicabangele ngokugcwele ukusebenza kwezindleko futhi sigweme ukuphishekela amanani aphansi ngobumpumputhe.
3. Naka isevisi yangemuva kokuthengisa kanye nenqubomgomo yewaranti
Lapho uthenga ama-valve anengcindezi ephansi, kuyadingeka ukuqonda isevisi yomkhiqizi ngemva kokuthengisa kanye nenqubomgomo yewaranti. Isevisi yekhwalithi ephezulu emva kokuthengisa kanye nenqubomgomo yewaranti ingaletha ukuvikeleka okwengeziwe kubasebenzisi futhi inciphise ubungozi bokusetshenziswa.
Ngamafuphi, ekuthengweni kwe-lama-valve we-ow-pressure , kufanele sicabangele ngokugcwele umkhiqizo, ikhwalithi, izinto ezibonakalayo, ukucaciswa, amamodeli nezinye izici, kuhlanganiswe nezidingo zangempela, khetha imikhiqizo engabizi kakhulu. Ngesikhathi esifanayo, qaphela isevisi emva kokuthengisa kanye nezinqubomgomo zokuqinisekisa ikhwalithi ukuze uqinisekise ukuthi ama-valve aphansi okuthengayo angahlangabezana nezidingo zokusetshenziswa futhi anciphise ingozi yokusetshenziswa.
