Incazelo emfushane yokusebenza kwedivayisi kagesi yama-valve amaningi (Uhlobo Z)

Incazelo emfushane yokusebenza kwedivayisi kagesi yamavalvu amaningi (Uhlobo Z) Idivayisi yokulawula ukugeleza, ingcindezi, nesiqondiso sokugeleza koketshezi (uketshezi, igesi, igesi-uketshezi, noma ingxube eqinile-ewuketshezi). Ibizwa ngokuthi "i-valve. Ngokuvamile iqukethe umzimba we-valve, ikhava ye-valve, isihlalo, izingxenye ezivulayo nezivalayo, indlela yokushayela, ama-seal kanye nezixhumi. Umsebenzi wokulawula we-valve ukuthembela kumshini wokushayela noma uketshezi ukushayela ukuphakamisa, ukushelela. , ukushwibeka noma ukuphenduka ukuze uguqule usayizi wendawo yokugeleza ukuze kuzuzwe. eShayina, ama-valve amanzi asetshenziswa eziteshini zokunisela, ama-valve okuhlola amapuleti asetshenziswa ekuncibilikiseni amapayipi, amapayipi oqalo kanye nama-valve okuhlola amapuleti asetshenziswa ekumbiweni kukasawoti emanzini ngokuthuthukiswa kobuchwepheshe bokuncibilikisa kanye nemishini yokudonsa amanzi. I-valve yepulaki yethusi kanye ne-lead yavela e-Europe Ngo-1681, kwavela ama-valve e-lever e-butterfly ngo-1769. Kamuva, ngenxa yokuthuthukiswa kwamandla kagesi, i-petroleum, imboni yamakhemikhali kanye nomkhakha wokwakha imikhumbi, ukusetshenziswa kwezinto ezintsha ezihlukahlukene, zonke izinhlobo zama-valve ziye zazalwa futhi zathuthukiswa ngokushesha, ukukhiqizwa kwama-valve kuye kwaba yingxenye ebalulekile yemboni yemishini kancane kancane. Amavalvu atholakala kabanzi. Ngokusho komsebenzi wokusetshenziswa, ingahlukaniswa: ① i-valve yokuvimba. Isetshenziselwa ukunqamula noma ukufaka phakathi ukugeleza okuphakathi, okuhlanganisa i-valve yesango, i-valve yembulunga, i-diaphragm valve, i-plug valve, i-valve yebhola, i-butterfly valve, njll. ② I-valve yokulawula. Ukuze ulawule ukugeleza nokucindezela koketshezi, ama-valve enziwe e-China ahlanganisa ama-valve alawulayo, ama-throttle valves, ama-valve okunciphisa ingcindezi nokunye. ③ Hlola i-valve. Isetshenziselwa ukumisa uketshezi ukuthi lungagelezi luye emuva. (4) vala i-shunt. Isetshenziselwa ukukhipha, ukuhlukanisa kanye nokuxuba uketshezi, okuhlanganisa ama-slide valves, ama-valve ezindlela eziningi, izicupho, njll. ⑤ Ivalvu yokuphepha. Isetshenziselwa ukuvikela ukuphepha kokucindezela ngokweqile, ukuvimbela i-boiler, isitsha sokucindezela noma ukulimala kwepayipi, njll Ngaphezu kwalokho, ngokusho kwengcindezi yokusebenza ingahlukaniswa i-vacuum valve, i-valve yokucindezela okuphansi, i-valve yokucindezela okuphakathi, i-valve yokucindezela okukhulu, i-valve ephezulu yokucindezela; Ngokusho kokushisa okusebenzayo kungahlukaniswa nge-valve yokushisa ephezulu, i-valve yokushisa ephakathi, i-valve yokushisa evamile, i-valve yokushisa ephansi; Ngokusho kwemodi yokushayela, ingahlukaniswa nge-valve ye-manual, i-valve kagesi, i-pneumatic valve, i-hydraulic valve, njll. Ngokusho kwe-valve impahla yomzimba ingahlukaniswa nge-cast iron valve, i-cast steel valve, i-valve yensimbi eyakhiwe, njll; Ngokwezici zomnyango wokusetshenziswa, ingahlukaniswa nge-valve yaseMarine, i-valve yokushisa amanzi, i-valve yesiteshi samandla nokunye. Imingcele eyisisekelo ye-valve ingcindezi yokusebenza, izinga lokushisa lokusebenza kanye ne-caliber. Amavalvu ahlukahlukene wamapayipi ezimboni, ngokuvamile asetshenziswa ukucindezela okuzisholo pN (ubukhulu bengcindezi yokusebenza evunyelwe ukuthwala ngaphansi kwezinga lokushisa elishiwo) kanye nobubanzi obuncane be-DN (ububanzi obuncane bomzimba we-valve nesiphetho sokuxhunywa kwepayipi) njengemingcele eyisisekelo. I-valve ivalwe ngokuyinhloko, amandla, ukulawulwa, ukujikeleza, ukuvula nokuvala ukusebenza, phakathi kwazo ezimbili zokuqala ziwukusebenza okuyisisekelo okubaluleke kakhulu kuwo wonke ama-valve. Ukuze kuqinisekiswe ukubekwa uphawu namandla valve, ngaphezu kwamazinga afanele kumele ihambisane design enengqondo, ukuqinisekisa izinga lenqubo, kodwa futhi kufanele kube izinto ezikhethiwe ngendlela efanele. Incazelo yokusebenza kwedivayisi kagesi ye-valve yama-multi-turn (uhlobo Z) Idivayisi kagesi ye-valve ye-multi-turn inomsebenzi ogcwele, ukusebenza okuthembekile, uhlelo lokulawula oluthuthukisiwe, usayizi omncane, isisindo esilula, kulula ukuyisebenzisa nokugcinwa, njll. *** isetshenziswa emandleni kagesi, insimbi, i-petroleum, imboni yamakhemikhali, ukwenza amaphepha, ukuthuthwa kwendle neminye iminyango. Idivayisi kagesi ye-valve yokujika eminingi, eyaziwa ngokuthi uhlobo lwe-Z. Ifanele idivayisi kagesi ye-valve yama-multi-turn ene-straight motion, eyaziwa ngokuthi uhlobo lwe-Z. Ifanele i-valve yokunyakaza eqondile, njenge-valve yesango, i-globe valve, i-diaphragm valve, isango lamanzi, njll. Isetshenziselwa ukuvulwa kwe-valve, ukuvala noma ukulungiswa, iyi-valve yokufinyelela isilawuli kude, isilawuli esimaphakathi kanye nokulawula okuzenzakalelayo kwedivayisi yokushayela ebalulekile. Multi - vula idivayisi kagesi, idivayisi yokushayela, ikhanda likagesi, imodeli yokufaka i-valve kagesi ye-Multi-rotary valve idivayisi kagesi imvelo yokusebenza: 3.2.1 Izinga lokushisa elizungezile: -20+60℃ (ama-oda akhethekile -60+80℃) 3.2.2 Izinga lokushisa elihlobene : 90%(ku-25℃) 3.2.3 Uhlobo olujwayelekile nohlobo lwangaphandle lusetshenziswa ezindaweni ezingenazo imidiya evuthayo/eqhumayo kanye negqwalayo; Imikhiqizo engaqhumi i-D ⅰ kanye ne-D ⅱ BT4, i-D ⅰ ifanele indawo engasebenzi yezimayini yamalahle; I-D ⅱ BT4 esetshenziswa ezimbonini, ilungele indawo ⅱ A, ⅱ B T1-T4 yeqembu lezingxube zegesi yocansi. (Bona i-GB3836.1 ukuze uthole imininingwane) 3.2.4 Ibanga lokuvikela: IP55 yohlobo lwangaphandle nolokuvikela ukuqhuma (IP67 ingenziwa ngendlela oyifisayo). 3.3.5 Uhlelo lokusebenza: imizuzu eyi-10 (imizuzu engama-30 ingenziwa ngokwezifiso). Idivayisi kagesi ye-valve eshintshashintshayo (Uhlobo Z) idivayisi yokushayela, ikhanda likagesi, idivayisi kagesi ye-valve, i-valve actuator, umshayeli wevalvu, ukusebenza kwe-valve kagesi ye-actuator Ngokwendawo yokusetshenziswa: Z wuhlobo oluvamile; I-ZW iwuhlobo lwangaphandle; I-ZB ayinamlilo; I-ZZ iwuhlobo olubalulekile; I-ZT iwuhlobo olulawulayo. Ngokusho kwamandla okukhiphayo: uhlobo lwe-torque nohlobo lwe-thrust. Ukusebenza komkhiqizo kuhambisana ne-JB/T8528-1997 "Izimfuneko zobuchwepheshe zedivayisi ye-valve yohlobo olujwayelekile". Ukusebenza kohlobo lokuvikela ukuqhuma kuvumelana nezinhlinzeko ze-GB3836.1-83 "Izimfuneko ezijwayelekile zemishini kagesi engaqhumi endaweni yocansi", GB3836.2-83 "Izinto zikagesi ezingaqhumi zezocansi Isisetshenziswa sikagesi esingashisi ilangabi D" kanye ne-JB/T8529-1997 "Izimo zobuchwepheshe zeDivaysi kagesi ye-valve engenamalangabi".
