I-Gland Packing I-valve yepulaki engu-4-08 yohlobo lokupakisha i-valve yepulaki I-valve yepulaki ye-Gland yokupakisha i-valve yepulaki ye-Gland 4-09 izinsimbi ezizivalayo ipulaki ipulaki epakisha uhlobo lwepulaki i-valve yama-self-sealins ipulaki Isivalo sepulaki se-Valve phakathi kwepulaki futhi sithembele kakhulu ekucindezelweni kwendawo ngokwayo ukuze kusetshenziswe uphawu lukawoyela I-valve yeqhude 4 kuya ku-10 ye-valve yepulaki I-valve yepulaki egcotshisiwe isebenzisa indlela yokulawula i-valve yeqhude uwoyela Ukwethulwa kafushane komshini olawula ama-valve, ukwethulwa kafushane kwendlela yokulawula i-valve Indlela yokulungisa iyisisetshenziswa esiguqula uguquko oluphumayo lwe-actuator lube kwi-actuator. ukushintsha indawo yokugeleza phakathi kwe-valve spool kanye nesihlalo se-valve. Ivamise ukubizwa ngokuthi umshini olawulayo wevalvu, njengokuthi iqonde ku-valve yesihlalo esisodwa, i-Angle valve, njll. Izici zayo zesakhiwo zingahlaziywa kulezi zici ezilandelayo. Ukwethulwa kafushane kwendlela yokulawula i-valve Kusukela ekugudluzweni kwe-valve core, indlela yokulawula ihlukaniswe yaba yi-valve yokugudluza eqondile kanye ne-angular displacement valve. Asetshenziswa ne-actuator yomugqa wokugudluka kanye ne-angular displacement actuator ngokulandelanayo. I-valve eqondile, i-engela valve, i-sleeve valve njalonjalo ingeye-valve ye-linear displacement, eyaziwa nangokuthi i-sliding stem valve (Sl> isuka kumhlahlandlela we-spool, ingahlukaniswa ngomhlahlandlela ophezulu, phezulu naphansi, · umhlahlandlela womkhono, umhlahlandlela wesiqu. kanye nomhlahlandlela wesihlalo kanye nezinye izinhlobo zokulawula uketshezi nokuvalwa, umhlahlandlela we-spool usetshenziselwa ukuqondanisa kwe-spool nesihlalo Umhlahlandlela ongaphezulu uqondiswa umkhono womhlahlandlela noma isakhiwo sokupakisha ikhava noma umzimba wevalvu; Umhlahlandlela ongaphezulu naphansi usebenzisa ikhava yevalvu kanye nomkhono womhlahlandlela wekhava yevalvu engezansi ukuze kuzuzwe umhlahlandlela, ivalvu yezihlalo ezimbili kanye nesidingo sokuqondisa indlela yokulawula isidingo sokusebenzisa umhlahlandlela ongaphezulu nophansi Umhlahlandlela uholwa indawo engaphandle ye-valve core kanye nengaphakathi lomkhono we-sleeve Le modi yomhlahlandlela inokusebenza okuzicabangela yona futhi iyakwazi ukubona ukuhleleka kwe-valve core kanye nesihlalo se-valve phezu kwesembozo se-valve kanye nendandatho yesihlalo se-valve, kanye nomkhono we-shaft kanye nesiqu se-valve kuyaqondiswa; Iziqondiso zezihlalo zisetshenziswa kuma-valve amancane okulawula ukugeleza aqondana ngqo nesihlalo. Ukwethulwa kafushane kwendlela yokulawula ama-valve Kusukela emandleni angalingani engqikithi ye-valve, umgogodla we-valve wendlela yokulawula unezinhlobo ezimbili ezingalingani futhi ezilinganayo. I-balanced spool iyi-spool enembobo yebhalansi evuliwe ku-spool. Lapho i-spool ihamba, ingxenye engaphezulu nephansi ye-spool ixhunywe ngenxa yembobo yebhalansi, ngakho-ke umehluko omkhulu wokucindezela phakathi kwezinhlangothi ezimbili uyasuswa ukuze unciphise umphumela wamandla angalingani ku-spool. I-spool elinganiselayo idinga ukulinganisa igumbi, ngakho-ke kuyadingeka ukuvala idivayisi. Ngokwesiqondiso sokugeleza, ingcindezi ye-balance spool ingaba ingcindezi ngaphambi kwe-valve (isikhungo sokuphuma) noma ingcindezi ngemva kwe-valve (ngaphandle kuya enkabeni). I-balance spool ingasetshenziselwa i-spool structure spool, futhi ingasetshenziselwa i-plunger structure spool. Zombili izinhlangothi ze-spool ezingalingani ziyingcindezi ngaphambi nangemuva kwe-valve ye-valve yokulawula. Ngakho-ke, amandla angalingani we-spool makhulu, futhi i-valve yokulawula yezinga elifanayo idinga i-actuator enomfutho omkhulu ukuze isebenze. Isethulo esifushane sendlela yokulawula i-valve Kusukela ku-valve core yokunciphisa ingcindezi, isakhiwo esiyinhloko se-valve sinokukhululeka kwengcindezi yesiteji esisodwa kanye nokukhululeka kwengcindezi yezigaba eziningi. Ngenxa yomehluko omkhulu wengcindezi phakathi kweziphetho ezimbili, isakhiwo sesiteji esisodwa sokuya phansi sifanele izikhathi ezinomsindo omncane futhi akukho cavitation enzima. Ezimfuneko eziphezulu zokunciphisa umsindo, izikhathi ezinzima ze-cavitation. Esikhathini se-multistage step-down structure, umehluko wengcindezi phakathi kweziphetho ezimbili ze-valve yokulawula uhlukaniswa ube umehluko wengcindezi eminingana, ukuze umehluko wengcindezi ebangeni ngalinye ube mncane, ngeke kwenzeke i-cavitation kanye ne-flash phenomenon, ukuze kuvinjwe i-cavitation. kanye ne-flash, kodwa futhi unciphise umsindo. Ukwethulwa kafushane kwendlela yokulawula i-valve Kusukela ekubukeni kwezimpawu zokugeleza, ngokusho kwezinguquko ezihlukene zendawo yokugeleza, ingahlukaniswa ngezici eziqondile, izici ezilinganayo zamaphesenti, izici zokuvula ngokushesha, izici ze-parabola, izici ze-hyperbolic nezinye izici zokulungisa. Izinga lokugeleza, i-J Bi, libonisa ubudlelwano phakathi kokususwa kwesiqu kanye nezinga lokugeleza. Ngokuvamile, izici zokugeleza zisetshenziselwa ukunxephezela izici ezingaqondile zento elawulwayo. Ukuma kwe-spool noma ukuma kwembobo yomkhono kunquma izici zokugeleza ze-valve yokulawula. Okuqondile, i-spool yenqubo ingahlukaniswa ngohlobo lwepuleti (ukuvulwa ngokushesha), uhlobo lwe-plunger, uhlobo lwefasitela kanye nohlobo lwemikhono. Ngenxa yokuguqulwa kwendawo yokuvula, indawo yokugeleza ihlukile lapho i-spool ihamba, ukuze kuzuzwe izici zokugeleza ezidingekayo. Ama-valve e-plunger namafasitela nawo ayatholakala ngezindlela ezihlukene kuye ngezici zokugeleza ezifunekayo. I-spool ye-Angle stroke valve nayo inezimo ezihlukene, isibonelo, ipuleti ye-valve yendabuko ye-butterfly valve, ipuleti le-valve yephrofayili eguquguqukayo; Ukuze i-valve yebhola i-O - imbobo, i-V - imbobo futhi ishintshiwe - isakhiwo somgodi. Ukwethulwa kafushane kwendlela yokulawula i-valve Kusukela ekushintshashintsheni kwezingxenye zangaphakathi ze-valve, ezinye izindlela zokulawula zezingxenye zangaphakathi ze-valve zingashintshwa kalula futhi zigcinwe, isibonelo, i-valve yomkhono ingashintshwa kalula ukuze kuzuzwe izici ezihlukahlukene zokugeleza; I-valve ebheke phezulu naphansi izingxenye zangaphakathi zingaphendula kalula i-spool nesihlalo ukuze kubonakale ukushintshwa kwevalve yomzimba ehlehlayo kanye ne-valve yomzimba ehlehlayo, ukuze kubonakale ukushintshwa kwemodi yokuvula komoya kanye nemodi yokuvala igesi; Ama-valve okuhlukanisa umzimba angasuswa kalula ukuze kushintshwe izihlalo nokuhlanza. Ukwethulwa kafushane kwendlela yokulawula i-valve Kusukela esakhiweni sekhava ye-valve, ngokwezidingo ezihlukene zohlelo lokusebenza, ungasebenzisa isembozo se-valve ejwayelekile, ungasebenzisa futhi isembozo se-valve yohlobo olude lwentamo noma ngokukhipha ukushisa noma ipuleti lokumunca ukushisa ende ikhava ye-valve yohlobo lwentamo, ngaphezu i-bellows seal uhlobo lwe-valve ikhava. AMAVAVAZI EZINTAMO Ezinde ASETSHENZISWA ISICELO ZESHISHINI ELIPHEZULU KANYE ELIPHANSI UKUVIKELA UKUPHAKISWA KWESIHLOKO EKUSEKENI ESIKHATHINI ESIPHAKATHI KANYE NOKUVIMBELA UKUMANDELA, UKUGQIBUKA, UKUVUZA NOMA UKUNCITSHISWA. Ngaphezu kokunwetshwa kwesembozo se-valve, izinga lokushisa lokupakisha kude nokushisa okuphakathi kokusebenza kwesembozo se-valve yentamo ende, kungase futhi kwandise ukuchithwa kokushisa noma ishidi lokumunca ukushisa, elenziwe ngokukhipha ukushisa noma ishidi lokumunca ukushisa kwesembozo se-valve yentamo ende. , ukuze izinga lokushisa eliphakathi lincishiswe noma lenyuke. Ngokuvamile, ikhava ye-valve yentamo ende inokuchithwa okungcono kokushisa kanye nokuguquguquka kokushisa okuphezulu, isetshenziswa ekusetshenzisweni kokushisa okuphezulu; IBONNET YEZINBILI ESINENKINGA ESIDE INENHLOKO IYANIKEZA UKUZIPHATHA OKUSHISAYO OKUPHANSI KANYE NOKUZIVUMELANA KAHLE KWETSHESHA ELIPHANSI UKUZE KUSENZISELWE ISICELO ESESIKHATHINI ESIPHANSI. Uma OKUPHAKATHI OKULAWULIWEYO INGAVUMELEKILE ukuthi kuvuze, IKHAVA engenhla YESAKHIWO SOKUPAKISHA ESAVAMILE asinakusetshenziswa, futhi ikhava engaphezulu enezivunguvungu kufanele isetshenziswe. Lokhu kwakhiwa KUSEBENZISA i-bellows seal ukuvala okuphakathi okulawulwayo emzimbeni we-valve, ngaphandle kokuthintana nokupakisha, ukuvimbela ukuvuza koketshezi. Umthelela wokucindezela kanye nezinga lokushisa le-bellows kufanele kubhekwe lapho ukhetha. Kusukela ekuxhumekeni komshini olawulayo kanye nepayipi, kunezinhlobo eziningana zokuxhunywa kwepayipi lesikulufa, uxhumano lwe-flange, uxhumano lwe-clanged clamp kanye nokuxhumeka kwe-welding. I-valve yokulawula encane ivame ukusebenzisa uxhumano lwentambo yepayipi elijikelezayo, ukuphela kokuxhumana komzimba we-valve kuyintambo yepayipi ye-taper, ukuphela kokuxhumeka kwepayipi kwentambo yepayipi ye-taper. Lokhu KUXHUMANA KUFANELE UKUXHUMANA KWAMAPHAYIPHA IMIZIMBA YOLAWUVU YOKULAWULA NGAPHANSI KOKUNGU-2 ". Cha, NGENKONZO YETHEMSHA ELIPHEZULU. Ngenxa yobunzima bokulungisa nokuqaqa, kuyadingeka ukuthi kufakwe izixhumi ezibukhoma phezulu naphansi komfula wevalvu yokulawula. Uxhumano lwe-flange yenziwe nge-flange ehambisana ne-valve yokulawula, exhunywe ngamabhawodi nama-gaskets, futhi i-flange ehambisanayo ishiselwe epayipini Ngokusho kwe-flange yokuxhumeka kwe-valve ehlukene, kukhona ama-flange ahlukene afanayo, njenge-flange eyisicaba, i-convex flange. I-flange ehlangene ye-annular, njll. I-flange esetshenzisiwe kufanele ihambisane nengcindezi yokusebenza elinganiselwe kanye nokushisa kwe-valve yokulawula i-Flange, i-gasket ingafakwa phakathi kobuso obubili be-flange, obufanele ukucindezela okuphansi, i-cast iron kanye ne-valve yokulawula yethusi. ukufakwa kwe-Convex flange processing kunomugqa wokuqinisa, i-groove encane egxilile ne-flange, lapho i-gasket ifakwe phakathi kwama-flanges amabili ngaphansi kwesenzo sokucindezela i-bolt, i-gasket izongena emseleni womugqa wokuqinisa, yenza uxhumano kwe-seal closer, uxhumano lwe-convex flange lufanele izinhlelo zokusebenza eziningi ezisetshenziswa ngensimbi ekhonjiwe, i-valve yokulawula insimbi ye-alloy.
