I-valve yeluvivane esakhiweni sesigaba se-soft seal kanye nesetfulo sekusebenta

Butterfly valve isetjentiswa kakhulu ekwakhiweni emadolobheni, petrochemical, metallurgy, emandla agezi kanye naletinye timboni emaphayiphini lasemkhatsini kwenta kunciphisa noma kulungisa kugeleza idivayisi engcono kakhulu. Butterfly valve isakhiwo ngokwayo kuyinto ekahle kakhulu kuvula nekuvala tincenye emaphayiphini, ngumcondziso wekutfutfukisa emaphayiphi namuhla tincenye tekuvula nekuvala. Sivame kuba ne-centre line soft seal butterfly valve, lesetjentiswa kakhulu ekushiseni lokujwayelekile, timo tekusebenta letinemfutfo lophansi, njengekuniketa emanti kanye nekukhipha emanti, emaphrojekthi ekonga emanti, kwakhiwa kwamasipala kanye naletinye tindzawo. Lokulandzelako ikakhulukati kwetfula ivalve yeluvivane le-eccentric yinye, ivalve yeluvivane le-eccentric lephindvwe kabili kanye nemikhicito yevalve yeluvivane le-eccentric letsatfu.

Kwekucala ngca, isakhiwo eccentric sinye se .Ivalvu levivane lethambile, situlo kuvala cross-section noma butterfly ipuleti ubukhulu sicondziso umugca equidistant kanye nesikhungo umjikelezo valve sicu sihlobo eccentric, ukuze valve butterfly enchubeni kuvulwa, butterfly ipuleti kuvala ebusweni kancane kancane kude valve situlo kuvala ebusweni. Butterfly ipuleti kujikeleta kuya 20 ~ 25 °, ipuleti butterfly kuvala ebusweni ngokuphelele ehlukaniswe valve situlo kuvala ebusweni, ukuze butterfly valve enchubeni kuvulwa, sihlobo umshini kugqoka kanye extrusion emkhatsini ebusweni lababili kuvala ebusweni kungaba improved butterfly kusebenta kungaba kakhulu. Lomklamo uncike kakhulu ekugucukeni kwe-elastic lokukhicitwa kukhishwa emkhatsini wepuleti levivane kanye nesihlalo sevalve kucinisekisa kuvalwa kwevalve yevivane.

Ngesisekelo valve eyodwa eccentric luvivane, sikhungo lesijikeletako ipuleti butterfly is offset kusukela umgca emkhatsini valve umzila ukugeleza, okwenta valve butterfly ifomu umphumela cam ngesikhatsi inqubo kuvulwa inqubo, ukuze ukuvala ebusweni butterfly ipuleti kungahlukaniswa kusuka ebusweni kuvala eccentric isakhiwo valve seat. Uma lelipuleti le butterfly lijikeleta libe ngu 8°~12°, indzawo yekuvala yelipuleti le butterfly ihlukaniswe ngalokuphelele nendzawo yekuvala yesihlalo se valve. Umklamo walesakhiwo unciphisa kakhulu kugcoka kwemishini lokuhlobene kanye nekugucuka kwe-extrusion emkhatsini waletindzawo letimbili tekuvala, lokwenta ncono kusebenta kwekuvala kwe-valve ye-butterfly.

Futsi ngesisekelo se .Ivalvu yevivane lephindvwe kabili, umugca losemkhatsini wendzawo yekuvala yesitulo wakha i-angular eccentricity ngemugca losemkhatsini wevalve, leyenta kutsi indzawo yekuvala yepuleti levivane ivele ihlukane nendzawo yekuvala yesitulo ngesikhatsi sekuvulwa ngesikhatsi senkambo yekuvula ipuleti le-butterfly se, futsi kuphela contacta ye-moment kanye nekucindzetela i-moment le. Le nhlanganisela leyehlukile ye eccentricity yenta kusetjentiswa ngalokugcwele kwemphumela we cam, kucedza ngalokuphelele kukhuhlana kwemishini kanye nekuguga emkhatsini wetindzawo letimbili tekuvala te vice yekuvala ye valve ye butterfly uma ivalve ivula futsi ivalwe, futsi isusa kungenteka kwekugucuka kanye nekuvuza. Le extruded seal ishintjwa ibe seal ye-torque, futsi kulungiswa kwemfutfo wekuvala kufezeka ngekulungisa i-torque yekushayela yangaphandle, kute kusebenta kwekuvala kanye nemphilo yenkonzo yesakhiwo se-eccentric lesitsatfu lesivaliwe se-valve se-butterfly kutfutfukiswe kakhulu.

Ngaphandle kwaloko, Tianjin Tanggu Water Seal Valve Co., Ltd. kuyinto tebuchwepheshe phambili irabha ehleti valve asekela emabhizinisi, imikhiqizo esihlalweni wafer luvivane valve, lug luvivane valve, kabili flange concentric luvivane valve, ibhalansi valve, wafer ipuleti kabili hlolaIvalvu Yekukhipha Umoya, Y-Strainer njalonjalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyatigcabha ngekuniketa imikhicito yesigaba sekucala lehlangabetana nemazinga laphakeme embonini. Ngeluhlu lwetfu lolubanti lwemavalvu kanye netimphahla, ungasetsemba kutsi sikunikete sisombululo lesiphelele seluhlelo lwakho lwemanti. Xhumana natsi namuhla kute utfole kabanti ngemikhicito yetfu nekutsi singakusita njani.
