Ivalve yevemvane yomugqa ophakathi iyisisetshenziswa esivamile sokulawula uketshezi, esinezici ezihlukile kanye nezinhlelo eziningi zokusebenza. Leli phepha lizokwethula izici, isimiso sokusebenza kanye nenkundla yokusetshenziswa kwe-valve uvemvane womugqa ophakathi, futhi lichaze ukubaluleka kwalo ekukhiqizeni izimboni.
Okokuqala, izici zomugqa ophakathi uvemvane valve
1. Isakhiwo esilula nesihlangene: i-valve butterfly yomugqa ophakathi yakhiwa umzimba we-valve, i-valve shaft, i-valve disc kanye nendandatho yokuvala uphawu, isakhiwo esilula nesihlangene. Uma kuqhathaniswa namanye ama-valve, i-valve yomugqa ophakathi nendawo incane ngosayizi, ilula ngesisindo, ikulungele ukufakwa, futhi yonga isikhala.
2. Ukusebenza okuguquguqukayo nokulula: induku yokusebenza ye-valve butterfly yomugqa ophakathi ingashintshwa ngamadigri angu-360, futhi ukusebenza kuyavumelana nezimo futhi kulula. Ngaphezu kwalokho, isivinini sokuvula nokuvala se-valve uvemvane womugqa omaphakathi siyashesha, esinganqamula ngokushesha noma sibushelelezi uketshezi.
3. Ukumelana nokugqwala okuqinile: Umzimba we-valve kanye ne-disc yomugqa ophakathi uvemvane valvu yenziwe ngensimbi engagqwali noma izinto ezimelana nokugqwala, ezinokumelana nokugqwala okuqinile. Ngakho-ke, i-valve ye-butterfly yomugqa ophakathi ifaneleka ukuphatha imidiya ehlukahlukene, kuhlanganise nemidiya edlayo.
4. Ukusebenza kahle kakhulu kokuvala: Ivalve uvemvane yomugqa omaphakathi ivalwe ngendandatho enwebekayo yokuvala, futhi ukusebenza kokuvala kuphakeme. Indawo yokuxhumana phakathi kwe-disc nesihlalo inkulu, futhi ukubekwa uphawu kunokwethenjelwa. Ngaphezu kwalokho, indandatho yokuvala yomugqa ophakathi uvemvane ingashintshwa ukuze kunwetshwe impilo yesevisi.
Okwesibili, isimiso sokusebenza somugqa ophakathi butterfly valve
Isimiso sokusebenza se-valve butterfly yomugqa ophakathi sisekelwe ekujikelezeni kwe-valve shaft kanye ne-disc ye-valve ukulawula ukugeleza koketshezi. Lapho i-disc i-perpendicular esihlalweni, i-valve iyavala, ivimbele uketshezi ukuthi lungadluli. Lapho i-disc ihambisana nesihlalo, i-valve iyavuleka ukuze uketshezi ludlule.
Induku yokusebenza yevalve uvemvane yomugqa omaphakathi iguqula ukunyakaza okuzungezisayo kube ukuzungezisa idiski ye-valve ngokudlulisa ngomshini, okulawula ukuvulwa nokuvala kwevalvu. I-valve disc ingavulwa kancane noma ivalwe ngomshini wokumanzisa ukuze kuncishiswe ukushaqeka komfutho we-fluid.
Okwesithathu, inkambu yesicelo yevalve yevemvane yomugqa ophakathi
1. Inkambu yezimboni: I-valve ye-butterfly ephakathi isetshenziswa kabanzi embonini yamakhemikhali, i-metallurgy, i-petroleum, amandla kagesi, ukwelashwa kwamanzi kanye nezinye izimboni zezimboni. Ingasetshenziselwa ukulawula ukugeleza nokucindezela koketshezi kanye nokulawula ukuthuthwa nokusabalalisa uketshezi ekukhiqizweni kwezimboni.
2. Ukuhlanza indle: Ivalve yevemvane yomugqa omaphakathi idlala indima ebalulekile ohlelweni lokuhlanza indle. Isetshenziselwa ukulawula ukugeleza kwe-inlet ne-outlet, ukulawula izinga lamanzi kanye nezinga lamanzi, nokuqinisekisa ukusebenza okuvamile kwesistimu yokuhlanza indle.
3. Inkambu yokwakha: Ama-valve ovemvane aphakathi nendawo asetshenziswa kakhulu ekuhlinzekweni kwamanzi nasezinhlelweni zokudonsa amanzi endaweni yokwakha. Isetshenziselwa ukulawula ukugeleza koketshezi ngaphakathi nangaphandle kwesakhiwo ukuze kusetshenziswe ngendlela ephephile futhi ephumelelayo yokunikezwa kwamanzi kanye nokukhipha amanzi.
4. I-Hvac: I-valve uvemvane yomugqa omaphakathi ingasetshenziswa ukulungisa ukuhamba kwamanzi okupholisa kanye nokushisisa amanzi ohlelweni lwe-HVAC ukuze kuzuzwe ukulawula izinga lokushisa kanye nemiphumela yokonga amandla.
Okwesine, ukubaluleka komugqa ophakathi uvemvane valve
Njengethuluzi elibalulekile lokulawula uketshezi, i-valve yevemvane yomugqa ophakathi idlala indima ebalulekile ekukhiqizweni kwezimboni. Okokuqala, i-valve ye-butterfly yomugqa ophakathi inezici zesakhiwo esilula futhi esihlangene, okwenza kube lula kakhulu ekufakweni nasekugcinweni, ukunciphisa ukutshalwa kwezimali kwabasebenzi kanye nezinsiza. Okwesibili, ukusebenza kwe-valve butterfly yomugqa ophakathi kuyavumelana nezimo futhi kulula, futhi uketshezi lungavulwa futhi luvalwe ngokushesha, okuthuthukisa ukusebenza kahle kokukhiqiza. Ukwengeza, i-valve ye-butterfly yomugqa ophakathi inezici zokumelana nokugqwala okuqinile kanye nokusebenza okungaphezulu kokuvala uphawu, ukuze ikwazi ukubhekana nezinhlobonhlobo zemidiya kanye nezindawo, ukuqinisekisa ukuphepha nokuthembeka kokulawula uketshezi.
Emkhiqizweni wezimboni, ukulawula okunembile kokugeleza kwamanzi nokucindezela kubalulekile. Ama-valve ovemvane angasetshenziswa ukulawula ukugeleza nokucindezela koketshezi futhi adlale indima ebalulekile ezinqubweni zezimboni. Isibonelo, embonini yamakhemikhali, i-valve ye-butterfly yomugqa ophakathi ingasetshenziswa ukulawula inani lamakhemikhali alethwa ukuze kuqinisekiswe ukuzinza nokuphepha kwenqubo yokukhiqiza. Embonini kawoyela, i-valve ye-butterfly ephakathi nendawo ingasetshenziswa ukulawula ukugeleza kwamafutha negesi ukuze kuzuzwe inqubo ebushelelezi yokuxhashazwa kwensimu kawoyela nokuhamba.
Ngaphezu kwalokho, ukusetshenziswa kwe-valve butterfly yomugqa ophakathi ohlelweni lokuhlanza indle nakho kubanzi kakhulu. Ingasetshenziselwa ukulawula ukugeleza kwe-inlet ne-outlet, ukulawula inqubo yokuhlanza indle, nokuqinisekisa ukuthi indle iphathwa kahle futhi ikhishwa.
Emkhakheni wokwakha, i-valve ye-butterfly ephakathi nendawo ivame ukusetshenziswa ekunikezeni amanzi kanye nezinhlelo zokudonsa amanzi. Ngokulawula ukuvulwa nokuvalwa kwe-valve, ukugeleza kwamanzi ngaphakathi nangaphandle kwesakhiwo kungalawulwa ukuze kuqinisekiswe ukusebenza okujwayelekile kokunikezwa kwamanzi nokukhipha amanzi.
Ekugcineni, i-valve uvemvane yomugqa omaphakathi nayo idlala indima ebalulekile ohlelweni lwe-HVAC. Ngokulungisa izinga lokuvula le-valve, ukugeleza kwamanzi okupholisa kanye nokushisa kwamanzi kungalawulwa ukuze kuzuzwe ukulawulwa kwezinga lokushisa kanye nomphumela wokonga amandla.
Kafushane, njengemishini yokulawula uketshezi olusetshenziswa kabanzi, i-valve ye-butterfly yomugqa ophakathi inezici zesakhiwo esilula futhi esihlangene, ukusebenza okuguquguqukayo nokulula, ukumelana nokugqwala okuqinile kanye nokusebenza kokuvala okuphakeme. Idlala indima ebalulekile ekukhiqizweni kwezimboni, ukuhlanza indle, ukwakhiwa kanye nezinkambu ze-HVAC, ukuhlinzeka ngezixazululo ezinokwethenjelwa zokulawula uketshezi kanye nokugqugquzela ukuthuthukiswa nokuqhubeka kwezimboni ezihlobene.
