Ama-valves ajwayelekile wesango ngokuvamile abhekisela kuma-valves wesango elivalwe kanzima. Le ndatshana ihlaziya ngokuningiliziwe umehluko phakathi kwama-valves afakwe uphawu athambile nama-valves ajwayelekile wesango. Uma wenelisekile ngempendulo, sicela unikeze i-vton izithupha phezulu.
Mane nje ubeke, ama-valves wesango afakwe uphawu athambile anezimpawu phakathi kwezinsimbi nezinsimbi, njenge-nylon \ tetrafluoroesene, kanye nama-valves avalwe kanzima yizimpawu phakathi kwezinsimbi nezinsimbi;
Ama-valves wesango elivalwe ngokuvalwa kanye nama-valves avalwe kanzima abhekisa ezintweni zokubopha zesihlalo se-valve. Izimpawu ezinzima zisetshenziswe kahle ngezinto zezihlalo ze-valve ukuqinisekisa ukunemba okufanayo nge-valve core (ibhola), insimbi engenasici engekho ngokuvamile nethusi. Izimpawu ezithambile zibhekisele ezintweni zokubopha ezigxile esihlalweni se-valve njengezinto ezingezona zensimbi. Ngoba izinto ezithambile ze-seal zinokuqina okuthile, izidingo zokunemba zokucubungula ziphansi kakhulu kunezimpawu ezinzima. Sibhekisa kwizici ze-vton ukuchaza umehluko phakathi kwama-valves wesango angeniswe angenisiwe kanye nama-valves wesango elivalwe kanzima.
1. Ukufaka uphawu
1. Izinto zokubopha zababili zihlukile.Ama-valves wesango elifakwe uphawuzivame ukwenziwa ngerabha noma i-polytetrafluorooroethylene. Ama-valualves wesango elivalwe kanzima enziwe ngezinsimbi ezifana nensimbi engenasici.
2 Lolu hlobo lwe-saint lunokusebenza okuhle kokubekwa uphawu, kepha akumelanga amazinga okushisa aphezulu, okulula ukugqoka, futhi kunezakhiwo ezingezinhle zemishini. Isibonelo: irabha lensimbi; I-TetraFloorooroorooroethylene yensimbi, njll. Isibonelo, uphawu olungenisa izihlalo olungenisa izihlaloI-Gate ValvI-E ye-vton ngokuvamile isetshenziswa emazingeni okushisa angaphansi kwe-100 ℃, futhi isetshenziselwa kakhulu amanzi okushisa egumbini.
I-3. I-Hard Seal: I-Seal Pair yenziwe ngezinto zensimbi noma ezinye izinto ezinzima ezinhlangothini zombili, ezibizwa ngokuthi "Hard Seal". Lolu hlobo lwe-SEAL lunokusebenza kabi kokubopha uphawu, kepha kumelana nokushisa okuphezulu, ukugqoka futhi kunezakhiwo ezinhle zemishini. Isibonelo: insimbi yensimbi; ithusi lensimbi; i-graphite yensimbi; insimbi yensimbi yensimbi; . Isibonelo, isango lensimbi engenasici angenisiwe ye-vton lingasetshenziselwa umusi, igesi, uwoyela namanzi, njll.
2. Ubuchwepheshe bokwakha
Imvelo ye-mission yomshini wemishini iyinkimbinkimbi, iningi lazo elingamazinga okushisa aphansi nengcindezi ephansi, ngokumelana okukhulu nokulimala okuqinile kwe-medium. Manje ubuchwepheshe sebuthuthukile, ngakho-ke ama-valves wesango elivalwe kanzima akhuthazwe kabanzi.
Ubudlelwano bunzima phakathi kwezinsimbi kufanele bubhekwe. Eqinisweni, i-valueve evalwe kanzima i-valuya ifana neyokubekwa uphawu okuthambile ngoba kuwuphawu phakathi kwezinsimbi. Umzimba we-valve uyadingeka ukuba lukhuni, futhi ipuleti le-valve kanye nesihlalo se-valve kumele kube njalo ukuze kufinyelelwe ukubekwa uphawu. Umjikelezo wokukhiqiza wama-valves wesango elivalwe kanzima mude.
3. Sebenzisa izimo
Ukuvalwa kwe-Seaning Effect Seals kufinyelela ukuvuza kwe-zero, kuyilapho izimpawu ezinzima zingaba phezulu noma ziphansi ngokwezidingo;
Izimpawu ezithambile zidinga ukushiswa umlilo, futhi ukuvuza kuzokwenzeka emazingeni okushisa aphezulu, kuyilapho izinsimbi ezinzima zingavuza. Izimpawu ezinzima ze-hard-off hard-off valve zingasetshenziswa ngaphansi kwengcindezi ephezulu, ngenkathi izimpawu ezithambile zingenakusetshenziswa. Ngalesi sikhathi, kudingeka i-Von's Hard hang valve valve valve.
Izimpawu ezithambile akufanele zisetshenziswe kwabezindaba ezithile ezilonakane, futhi kusetshenziswe uphawu olunzima;
4. Izimo Zokusebenza
Izimpawu ezinzima zingaba phezulu noma ziphansi ngokwezidingo; Izimpawu ezithambile kumele zibe yiproveroof fireproof, futhi izimpawu ezithambile zingafinyelela uphawu oluphezulu. Ngoba emazingeni okushisa aphansi aphansi, izimpawu ezithambile zizovuza, ngenkathi izimpawu ezinzima zingenayo le nkinga; Izimpawu ezinzima zivame ukumelana nezingcindezi eziphakeme kakhulu, ngenkathi izimpawu ezithambile azikwazi. Isibonelo, ama-valves wesango lensimbi angenisiwe e-vton asebenzisa uphawu olunzima, futhi ingcindezi ingafinyelela ku-32mpa noma i-2500lb; Izilonda ezithambile azikwazi ukusetshenziswa kwezinye izindawo ngenxa yokugeleza okuphakathi nendawo, njengemidiya ethile eqinile); Ekugcineni, ama-hard seal valves ngokuvamile abiza kakhulu kunezimpawu ezithambile. Ngokuqondene nokwakhiwa, umehluko phakathi kwalokhu okubili akukukhulu, umehluko omkhulu yisihlalo se-valve, uphawu oluthambile alunangqondo, futhi uphawu olunzima luyinsimbi
V. Ukukhetha imishini
Ukukhethwa kophawu oluthambile nolukhuniama-gang valveskusekelwe ikakhulu kwinqubo ephakathi nendawo, izinga lokushisa kanye nengcindezelo. Ngokuvamile, uma i-medium iqukethe izinhlayiya eziqinile noma igqoke noma izinga lokushisa liphakeme kunama-degree angama-200, kungcono ukusebenzisa izimpawu ezinzima. Isibonelo, umusi wokushisa aphezulu ngokuvamile azungeze ngo-180-350 ℃, ngakho-ke kufanele kukhethwe i-valve yesango le-hard poal.
6. Umehluko ngentengo nezindleko
Nge-caliber efanayo, ingcindezi kanye nezinto ezibonakalayo, okungeniswa ngaphakathi kanzimaama-gang valveskubiza kakhulu kunamavalovu wesango elifakwe uphawu ezweni; Isibonelo, i-Vonton's DN100 engenisiwe yensimbi yensimbi yensimbi i-40% ebiza kakhulu kune-DN100 evulekile yensimbi ethambile yesango elivaliwe; Uma zombili ama-valves wesango elivalwe kanzima nama-valves afakwe uphawu afakwe ngaphansi kwezimo zokusebenza, lapho ucubungula izindleko, zama ukukhetha ama-valves afakwe uphawu ongenyelwe okufakwe uphawu okuvundwayo.
7. umehluko empilweni yenkonzo
U-Soft Seal usho ukuthi uhlangothi olulodwa lwe-seal pair lwenziwe ngezinto ezibonakalayo ezinobulukhuni obuphansi. Ngokuvamile, isihlalo se-seal esithambile senziwa ngezinto ezingezona zensimbi ngamandla athile, ubunzima kanye nokumelana nokushisa. Inokusebenza okuhle kokubekwa uphawu futhi ingafinyelela ukuvuza kwe-zero, kepha impilo yayo nokuvumelana nezimo zokushisa kumpofu. Izimpawu ezinzima zenziwe ngensimbi futhi zinokusebenza kokubekwa uphawu okumpofu, yize abanye abakhiqizi bethi bangakwazi ukufeza ukuvuza kwe -ro.
Inzuzo yezimpawu ezithambile ukusebenza kahle kokubekwa uphawu, futhi okungekho emthethweni kungukuguga okulula, ukugqoka nokuklebhula, kanye nempilo yenkonzo emfushane. Izimpawu ezinzima zinempilo yenkonzo ende, kepha ukusebenza kwazo kokubekwa uphawu kumpofu kakhulu uma kuqhathaniswa nezimpawu ezithambile. Lezi zinhlobo ezimbili zezimpawu zingahambelana. Mayelana nokubekwa uphawu, izimpawu ezithambile zingcono kakhulu, kepha manje ukubekwa uphawu kwezimpawu ezinzima nakho kungahlangabezana nezidingo ezihambisanayo.
Izimpawu ezithambile azikwazi ukufeza izidingo zenqubo kwezinye izinto zokuwohloka, kepha izimpawu ezinzima zingaxazulula le nkinga!
Lezi zinhlobo ezimbili zezimpawu zingahambelana. Mayelana nokubekwa uphawu, izimpawu ezithambile zingcono kakhulu, kepha manje ukubekwa uphawu kwezimpawu ezinzima nakho kungahlangabezana nezidingo ezihambisanayo!
Inzuzo yezimpawu ezithambile ukusebenza kahle kokubekwa uphawu, futhi okungekho emthethweni kungukuguga okulula, ukugqoka nokuklebhula, kanye nempilo yenkonzo emfushane.
Izimpawu ezinzima zinempilo yenkonzo ende, kepha ukubekwa uphawu kuyinto kubi kakhulu kunezimpawu ezithambile.
