Incazelo ye-butterfly valve operation: manual, kagesi noma i-pneumatic?

I-center line butterfly valve iyisisetshenziswa sokulawula uketshezi, esisetshenziswa kabanzi ezimbonini ezahlukahlukene. Inezinzuzo zesakhiwo esilula, usayizi omncane kanye nokusebenza okulula, ngakho-ke ithandwa ngabasebenzisi. Ekusetshenzisweni okusebenzayo, ngokwezidingo, imodi yokusebenza yevalve uvemvane yomugqa ophakathi ingahlukaniswa ngezinhlobo ezintathu zemanuwali, zikagesi nezomoya. Lesi sihloko sizokwethula lezi zindlela zokusebenza ezintathu ngokuningiliziwe. Okokuqala, imodi yokusebenza okwenziwa ngesandla: Ukusebenza ngezandla kuyindlela eyisisekelo yokusebenza kwevalvu yevamvane yomugqa ophakathi. Ilawula izinga lokugeleza kwe-medium ngokuzungezisa isiqu ukuze kulungiswe ukuvulwa kwe-valve disc. Imodi yokusebenza yemanuwali ilungele izikhathi ezithile ezilula, njengokushintshwa kokugeleza kuncane, imvamisa yokusebenza ayiphezulu. Izinzuzo zokusebenza ngezandla zilula futhi zithembekile. Umsebenzisi angakwazi ukwahlulela ngokuqondile izinga lokuvula nokuvala le-valve ngokubheka indawo ye-valve disc. Ngaphezu kwalokho, izinto zokusebenza nezindleko ezidingekayo ekusebenzeni ngezandla ziphansi, futhi ukunakekelwa nokulungiswa nakho kulula kakhulu. Kodwa-ke, indlela yezandla nayo inobubi obuthile. Okokuqala, ukusebenza ngezandla kudinga ukubamba iqhaza ngesandla, izinga lobuchwepheshe lomsebenzisi liphakeme, kanye nesidingo sokutshala izimali eziningi zabantu. Ngaphezu kwalokho, isivinini sokuphendula sokusebenza okwenziwa ngesandla sihamba kancane, futhi asikwazi ukuhlangabezana nezidingo zokunye ukusabela okusheshayo. Okwesibili, imodi yokusebenza kagesi: Imodi yokusebenza kagesi iyizinga eliphezulu lokuzishintshanisa kumodi yokusebenza kwevalve yevemvane. Ishayela ukuzungezisa kwesiqu se-valve ngenjini ukuze ibone ukulawulwa kokuvula nokuvala kwediski ye-valve. Uma kuqhathaniswa nemodi yokusebenza ngesandla, imodi yokusebenza kagesi inokunemba okuphezulu kokulawula kanye nesivinini sokuphendula esisheshayo. Inzuzo yokusebenza kukagesi ukuthi inezinga eliphezulu lokuzenzekelayo futhi ingakwazi ukufeza ukulawula okukude nokulawula okuzenzakalelayo. Ngokubambisana nesistimu yokulawula, ingakwazi ukubona ukulawula uketshezi kwesikhathi kanye nenani, ithuthukise ukusebenza kahle kokukhiqiza futhi inciphise ukusebenza kwesandla. Ngaphezu kwalokho, imodi yokusebenza kagesi nayo ingafinyelela ukulawulwa kwempendulo yesikhundla se-valve, ithuthukise ukuphepha nokuzinza. Kodwa-ke, okubi kokusebenza kukagesi yizindleko eziphezulu zemishini kanye nokugcinwa okuyinkimbinkimbi. Imodi kagesi yokusebenza ihilela okokusebenza okunjengamamotho, amasistimu okulawula nezinzwa, futhi kudinga ukuhlolwa nokugcinwa njalo ukuze kuqinisekiswe ukusebenza kwawo okuvamile. Ngaphezu kwalokho, ngoba imodi yokusebenza kagesi incike ekunikezeni amandla, uma ukwehluleka kwamandla, kungase kuthinte ukusebenza okuvamile kwe-valve. Okwesithathu, imodi yokusebenza komoya: Imodi yokusebenza kwe-pneumatic ukusebenzisa idivayisi yomoya ukulawula ukuvulwa nokuvalwa kwevalve uvemvane womugqa omaphakathi. Ishayela ukujikeleza kwesiqu se-valve ngokushintsha umfutho womoya. Imodi yokusebenza kwe-pneumatic inezinzuzo zejubane lokuphendula ngokushesha nokuthembeka okuphezulu. Izinzuzo zokusebenza kwe-pneumatic ukuphendula okusheshayo kanye nezinga eliphezulu lokuzenzekelayo. Ngokusebenzisana nesistimu yokulawula umoya, isilawuli kude nokulawula okuzenzakalelayo kungafinyelelwa ukuze kuhlangatshezwane nezidingo zokuphendula ngesivinini esikhulu nokugeleza okukhulu. Ngaphezu kwalokho, ukusebenza kwe-pneumatic kungalungisa izinga lokucindezela kanye nokugeleza ngokuvumelana nezidingo zenqubo yokulawula okunembile. Kodwa-ke, okubi kokusebenza kwe-pneumatic ukuthi izindleko zemishini ziphezulu, futhi ukugcinwa nokulungiswa kuyinkimbinkimbi. Ukusebenza kwe-pneumatic kudinga imishini yomthombo womoya kanye nesistimu yokulawula umoya, okwandisa ubunzima nezindleko zemishini. Ngaphezu kwalokho, imodi yokusebenza kwe-pneumatic nayo idinga ukuhlolwa nokugcinwa njalo ukuze kuqinisekiswe ukuzinza komthombo womoya kanye nokuthembeka kokusebenza. Imodi yokusebenza ye-valve butterfly yomugqa ophakathi ingakhethwa ngesandla, ngogesi noma nge-pneumatic ngokusho kwesidingo sangempela. Ukusebenza ngezandla kulula futhi kuthembekile, kulungele izikhathi ezithile ezilula; Imodi yokusebenza kagesi inenzuzo yokuzenzakalela nokulawula okunembile, okufanele izimo ezidinga ukunemba okuphezulu nokuphendula okusheshayo; Imodi yokusebenza kwe-pneumatic inesivinini sokuphendula esisheshayo nokuthembeka okuphezulu, futhi ifanele izidingo zesilinganiso esikhulu sokugeleza nokusabela kwesivinini esikhulu. Lapho kukhethwa indlela yokusebenza, izici ezifana nezidingo zenqubo, indawo yokusebenza, ukunemba kokulawula kanye nezindleko kufanele zicatshangelwe. Ngesikhathi esifanayo, imodi yokusebenza ekhethiwe idinga ukugcinwa futhi ihlolwe njalo ukuze kuqinisekiswe ukusebenza kwayo okuvamile nokwethembeka. Ngithemba ukuthi lesi sihloko sizokusiza uqonde imodi yokusebenza ye-valve butterfly yomugqa ophakathi, futhi ukhethe imodi yokusebenza efanele ekusetshenzisweni okusebenzayo ukuze uthuthukise ukusebenza kahle nokuthembeka kokulawula uketshezi. Ivalve uvemvane yomugqa ophakathi
