I-ZFA Valve igxile ekukhiqizeni zonke izinhlobo zama-butterfly valve. Uma amakhasimende enesidingo, singathenga i-electric actuator yemikhiqizo yamazwe ngamazwe noma imikhiqizo eyaziwayo yaseShayina egameni lethu, bese siyinikeza amakhasimende ngemva kokulungisa amaphutha ngempumelelo.
An ivalvu yebhabhathane kagesiiyivalvu eqhutshwa yimoto kagesi futhi isetshenziselwa ukulawula ukugeleza koketshezi noma igesi. Ngokuvamile inevalvu yebhabhathane, imoto, idivayisi yokudlulisa kanye nohlelo lokulawula.
Umgomo osebenzayo wevalvu yebhabhathane kagesi ukushayela idivayisi yokudlulisa ngemoto ukuze ijikeleze ipuleti yevalvu, ngaleyo ndlela ishintshe indawo yesiteshi soketshezi emzimbeni wevalvu futhi ilungise izinga lokugeleza. Ivalvu yebhabhathane kagesi inezici zokuvula nokuvala okusheshayo, isakhiwo esilula, usayizi omncane, isisindo esincane, kanye nokonga amandla.
1. Umqondo wamamaki enjini angangeni manzi futhi angaqhumi
Izinga lenjini elingangeni manzi libhekisela kungcindezi yamanzi kanye namazinga okujula kwamanzi injini engawamelana nawo ngaphansi kwezimo ezahlukene ezingangeni manzi. Ukuhlukaniswa kwamazinga enjini angangeni manzi kuhloswe ukuhlangabezana nezimo ezahlukene zokusetshenziswa kanye nezidingo zokuqinisekisa ukusebenza okuvamile kanye nokuphila kwenkonzo yenjini. Izinga lenjini elingangeni manzi libhekisela ekhonweni lenjini lokugwema ukubangela ukuqhuma lapho isebenza endaweni eyingozi.
2. Ukuhlukaniswa kwamamaki emoto angangeni manzi
1. IPX0: Ayikho izinga lokuvikela futhi ayikho umsebenzi wokuvimbela amanzi.
2. IPX1: Izinga lokuvikela liwuhlobo lokuconsa. Uma injini iconsa amanzi ngendlela eqondile, ngeke ibangele umonakalo kunjini.
3. IPX2: Izinga lokuvikela liwuhlobo lokuconsa oluthambekele. Uma injini iconsa amanzi nge-engeli yama-degrees angu-15, ngeke ibangele umonakalo kunjini.
4. IPX3: Izinga lokuvikela liwuhlobo lwamanzi emvula. Uma injini ifafazwa ngamanzi emvula kunoma iyiphi indlela, ngeke ilimaze injini.
5. IPX4: Izinga lokuvikela liwuhlobo lokufutha ngamanzi. Uma injini ifuthwa ngamanzi kusuka kunoma iyiphi indlela, ngeke ilimaze injini.
6. IPX5: Izinga lokuvikela liwuhlobo lokufutha amanzi oluqinile. Injini ngeke yonakale uma ifuthwa ngamanzi aqinile kunoma iyiphi indlela.
7. IPX6: Izinga lokuvikela liwuhlobo lokugeleza kwamanzi okuqinile. Injini ngeke yonakale uma ibhekene nokugeleza kwamanzi okunamandla kunoma iyiphi indlela.
8. IPX7: Izinga lokuvikela liwuhlobo lokucwiliswa kwesikhashana. Injini ngeke yonakale uma icwiliswa emanzini isikhathi esifushane.
9. IPX8: Izinga lokuvikela liwuhlobo lokucwiliswa isikhathi eside. Injini ngeke yonakale uma icwiliswa emanzini isikhathi eside.
3. Ukuhlukaniswa kwamabanga emoto angaqhumi
1. Izinga lokumelana nokuqhuma kwe-Exd: Ama-motor e-exd asebenza egobolondweni elivaliwe elingamelani nokuqhuma ukuze kuvinjelwe ukuqhuma okubangelwa yizinhlansi noma ama-arcs ngaphakathi kwe-motor. Le moto ifanele ukusetshenziswa ezindaweni ezivutha amalangabi noma ezishisayo.
2. Izinga elimelana nokuqhuma kwe-Exe: Ama-motor e-Exe grade afaka ama-terminals e-motor kanye nokuxhumeka kwekhebula endaweni evalekile engamelana nokuqhuma ukuze kuvinjelwe izinhlansi noma ama-arcs ukuthi angaphumi. Le moto ifanele ukusetshenziswa ezindaweni ezine-vapor evuthayo.
3. Izinga lokumelana nokuqhuma kwe-Ex n: Ama-motor e-Exn level anezingxenye zikagesi ezingamelani nokuqhuma ezifakiwe ngaphakathi kwe-casing ukuze kuncishiswe ukukhiqizwa kwezinhlansi nama-arcs. Le moto ifanele ukusetshenziswa ezindaweni ezivutha igesi noma umusi.
4. Izinga lokumelana nokuqhuma: Ama-motor asezingeni lokuqhuma anezingxenye zikagesi ezimelana nokuqhuma ezifakwe ngaphakathi kwebhokisi ukuze avikele izingxenye zikagesi ezingaphakathi kwemoto kumagesi avuthayo noma umusi. Lolu hlobo lwemoto lufanelekela ukusebenza ezindaweni ezinamagesi avuthayo noma umusi.
4. Izici zamabanga enjini angangeni manzi futhi angaqhumi
1. Uma izinga lenjini engangeni manzi futhi engaqhumi liphezulu, kulapho injini isebenza kahle khona, kulapho ingcindezi yamanzi kanye nokujula kwamanzi ingamelana nakho kukhulu khona futhi kulapho isebenza kahle khona ekulweni nobungozi.
2. Ukuthuthukiswa kwezinga lenjini engangeni manzi futhi engaqhumi kuzokhulisa izindleko zenjini, kodwa kungathuthukisa impilo yesevisi kanye nokuthembeka kwenjini.
3. Ukukhethwa kwebanga lenjini elingangeni manzi nelingaqhumi kufanele kusekelwe endaweni yokusetshenziswa yangempela kanye nezidingo zokuqinisekisa ukusebenza okuvamile kanye nokuphila kwenkonzo yenjini.
Ngamafuphi, izinga lokungangeni manzi nelingaqhumi lenjini liyisici esibalulekile ekuqinisekiseni ukuphepha. Amazinga ahlukene afanelekela izindawo eziyingozi ezahlukene, futhi amazinga nemithethonqubo efanele yokuphepha kudingeka ilandelwe ngokuqinile.
