Indlela yokukhetha i-valve kagesi efanele? Ukuhlaziywa kwezici zokusebenza kwe-valve kagesi engaqhumi

I-valve kagesi epayipini isetshenziselwa ikakhulukazi ukwenza ukuvimbela, ukusatshalaliswa nokuguqula isiqondiso somsebenzi we-medium, idinga kuphela ukuzungeza ama-degree angama-90 okulawula futhi umzuzu omncane wokugoqa ungavalwa ngokuqinile, khetha ukufakwa okunembile kagesi ukuvimbela i-torque. incane kakhulu, ayikwazi ukushintsha i-valve kagesi, khetha ukufakwa kukagesi okufanele unake: I-torque yokulawula iyipharamitha eyinhloko yokukhetha idivayisi ye-valve kagesi. I-torque ephumayo yedivayisi kagesi kufanele ibe izikhathi ezingu-1.2 ~ 1.5 ze-torque ye-tripod yokulawula i-valve.

Kunezakhiwo ezimbili eziyinhloko zedivayisi ye-valve kagesi: eyodwa ayilungiselelwe nge-thrust disc, i-torque ephumayo eqondile; Okunye ukucushwa kwe-thrust disc, i-torque ephumayo nge-thrust disc stem nut iye ku-thrust okukhiphayo.

Inombolo yezindandatho eziginqikayo ze-shaft ephumayo yedivayisi ye-valve kagesi ihlobene nobubanzi obujwayelekile be-valve stem pitch kanye nenani lezintambo. Ibalwa ngokuvumelana ne-M=H/ZS (M iyingqikithi yenani lezindandatho eziginqikayo idivayisi kagesi okufanele yaneliseke ngayo, H ubude obuvulayo besiqu se-valve, u-S uyingqikithi yentambo ye-valve stem drive kanye no-Z inombolo ye-valve stem thread).

Ububanzi besiqu se-valve ye-stem evulekile yohlobo lwe-multi-turn, uma idivayisi kagesi ivumile ukudlula ububanzi be-stem enkulu ayikwazi ukudlula isiqu se-valve ye-valve, ayikwazi ukubuthelwa ku-valve kagesi.

Ngakho-ke, ububanzi bangaphakathi bomgodi wokuphuma ongenalutho wedivayisi kagesi kufanele bube bukhulu kunobubanzi obungaphandle besiqu se-valve ye-valve yenduku evulekile. Ukuze ama-valve enduku emnyama emnyangweni ama-rotary valve kanye nama-valve amaningi ajikelezayo, nakuba ububanzi be-valve stem kungadingeki kucatshangelwe, ububanzi be-valve stem kanye nosayizi wendlela ebalulekile kufanele futhi kucatshangelwe ngokugcwele ekukhethweni, ukuze umhlangano. ingasebenza ngokujwayelekile.

Uma isivinini sokuvula nokuvala se-valve yesivinini esiphumayo sishesha kakhulu, kulula ukukhiqiza umkhuba wokushaywa kwamanzi. Ngakho-ke, isivinini esifanele sokuvula nokuvala kufanele sikhethwe ngokuvumelana nezimo ezihlukene zokusetshenziswa.

Ukuhlaziywa kwezici zokusebenza kwe-valve kagesi engaqhumi

Ukuhlaziywa kwezici zokusebenza kwe-valve kagesi engaqhumi

I-valve kagesi evimbela ukuqhuma ihlukaniswe kakhulu ngokuthi: i-valve yebhola kagesi engaqhumi; I-valve yevemvane kagesi engaqhumi; I-valve yevemvane yokuphefumula kagesi engaqhumi; I-valve yebhola ye-fluorine engaqhumi; I-valve yevemvane efakwe umugqa kagesi engaqhumi; I-valve kagesi yohlobo lwe-V engaqhumi; I-valve yevemvane ethambile kagesi engaqhumi; I-valve yevamvane ye-clamp kagesi engaqhumi; I-valve ye-butterfly kagesi yokulungiswa kokumelana nokuqhuma; I-valve yebhola kagesi evimbela ukuqhuma nokunye empilweni yamanje iye yaba sesimweni esithandwa kakhulu, futhi ukusetshenziswa kwalokhu okungenhla masikwazi ukuphumelela kakhulu ukuqonda nokujwayelana nakho, kunemisebenzi eminingi, ukuze thina kungaba ukusetshenziswa okuphumelelayo kakhulu ngeke kwenze amaphutha, indawo yokusetshenziswa kwayo okudingeka siyinake akufanele ibekwe endaweni yokushisa ephezulu, Futhi ngokusho kwezici zesikhala ezifanele ukuze zisetshenziswe ngempumelelo, sidingeka kakhulu ukunquma nokuqonda izici zayo, azikwazi ukubekwa elangeni eliqondile, ukuze kwenzeke umonakalo wecala lomshini, noma ulayini wangaphakathi wenzeke ngaphezu kwenkinga okubangele ukusetshenziswa okuphelele kwalokhu okungenhla.

I-actuator kagesi efakazela ukuqhuma nebhola le-valve yebhola, i-actuator yamukela umklamo odidiyelwe, ukufakwa kwamandla kagesi okungu-220V kungaba ngokuqondile ukushintsha ukulungiswa komthamo, nemojula eyakhelwe ngaphakathi ye-servo, isiginali yokulawula okokufaka (4 ~ 20mADC noma 1 ~ 5VDC) kanye ne-single- amandla esigaba angalawula ukusebenza. Ibanga lokuvikela i-valve yebhola likagesi elingaqhume ibanga le-dⅡBT4, izinga lokuvikela le-IP67, elinedivayisi yokulawula yasenkambu. I-valve yebhola evikela ukuqhuma kagesi ibonakala ngokuthi: akukho mandla, isibambo se-clutch singasebenza ngesandla. Uma inikwe amandla, i-clutch iqala kabusha ngokuzenzakalelayo. Isiqondiso sokugeleza singaba ngokunganaki, ububanzi obuguquguqukayo, singasetshenziselwa ukucindezela okuphezulu kanye nezikhathi ezinkulu zobubanzi, ukulawula i-viscosity ephezulu, nge-fiber kanye nemidiya yezinhlayiyana ezinhle.

I-valve uvemvane elingaqhumi kagesi yakhiwe ama-valve evemvane e-eccentric kanye ne-actuator kagesi. Ifomu lesakhiwo se-butterfly-proof valve structure: Isakhiwo se-eccentric ezintathu kanye nesakhiwo esisodwa se-eccentric, ifomu lophawu: uphawu lwensimbi kanye nesakhiwo sophawu oluthambile. I-valve ye-butterfly evimbela ukuqhuma kagesi ihlukaniswe yaba izinhlobo ezimbili: uhlobo lwe-flange nohlobo lwe-clamp. In the lokushisa ngezansi 150 degrees angakhethwa PTFE uphawu uvemvane valve, izinga lokushisa eliphezulu zingakhethwa ezintathu eccentric hard seal valve umzimba. I-valve ye-butterfly elawula i-explosion-proof ingasetshenziswa kabanzi ekudleni, ekuvikelweni kwemvelo, embonini yokukhanya, i-petroleum, imboni yamakhemikhali, imishini yokufundisa, ukwenza iphepha, amandla kagesi nezinye izimboni zesistimu yokulawula othomathikhi yezimboni. I-valve yevemvane engaqhumisi kagesi ekudleni, emithini, kumakhemikhali, kuphethiloli, amandla kagesi, endwangu, ephepheni kanye nokunye ukuphakelwa kwamanzi kanye ne-drainage, ipayipi legesi lokulawula ukugeleza kanye nendawo yokunqanda.

Uyazi ukuthi ungayisebenzisa kanjani ngokunembile i-valve kagesi engaqhumi ukuze ukuphila nokusebenza kwemishini kusetshenziswe kahle? Uma kwenzeka ungazi, nakhu ukubheka kancane.

1. Uma usebenzisa amavalvu kagesi angaqhumi, kufanele uqale uqinisekise ngokuphindaphindiwe ukuthi zonke izakhiwo ziyahambisana ngaphambi kokuthi ugijime. Amakhasimende amaningi athintwa ukuhlola ngokunganaki, okuthinta impilo yesevisi kanye nomsebenzi wemishini.

I-2, ngemuva kokusebenza kwe-valve kagesi evimbela ukuqhuma, ungabi nzima kakhulu ukulawula imishini, kodwa kancane kancane ukulawula uma amandla angaphandle makhulu kakhulu, akakwazi ukwandisa umsebenzi wemishini ezokwenza izingxenye ze imishini ngenxa yamandla angaphandle ngokweqile kanye nokuhlanekezela, ngaleyo ndlela kuthinte okokusebenza.

Izici zomsebenzi we-valve kagesi engaqhumi:

1, thuthukisa owandulela ubuchwepheshe bokuxhuma iphinikhodi, ukuze umsebenzi wokuvala uphawu uthembeke kakhulu, impilo ende yesevisi, ukugcinwa kalula

I-2, ukusetshenziswa kwe-electroplating, inayiloni nezinye izigqoko ezihlukene, ukumelana nokugqwala kuyathuthukiswa, kungahlangabezana nezidingo zezimayini ezahlukene.

3, ukubukeka valve usebenzisa spray enamathela, ukuze ukubukeka umkhiqizo anticorrosion intuthuko, ukubukeka enhle.

I-4, umsebenzi wedivayisi kagesi, izici zayo zimi kanje:

1) Incane futhi ilula, kulula ukuyihlakaza nokulungisa, futhi ingafakwa kunoma iyiphi i-Engeli

2) Igobolondo le-aluminium alloy die-cast linganciphisa ukuphazamiseka kwe-electromagnetic

3) Idizayini ehlanganisiwe ye-worm gear okukhipha shaft ukugwema igebe lokuxhumana okubalulekile kanye nokunemba okuphezulu kokudlulisela

I-4) I-shaft ephumayo yegiya lezikelemu eliphonswe nge-alloy yethusi inamandla aphezulu kanye nokumelana okuhle kokugqoka

I-5) I-Microswitch enokungena okugcwele, ivuleke futhi ivaliwe, iphephe kakhudlwana ukuyisebenzisa

6) Izinhlobonhlobo zezimpawu zokukhiphayo: uhlobo lokushintsha, uhlobo lwesilawuli, uhlobo oluhlakaniphile

I-7) Ngokuvikelwa kokushisa ngokweqile, umsebenzi wokuvikela ukugcwala ngokweqile, ukuphepha kuqinisekisiwe
