I-China U Type Butterfly Valve mveliso kunye nabavelisi

Ivalvu yeButterfly yohlobo lwe-U

Inkcazo emfutshane:

Iivalvu yebhabhathane yohlobo lwe-U ephindwe kabiniYakhiwe ngendlela efanayo neyakhiwe ngohlobo lwe-wafer, kodwa inee-flanges ezidibeneyo kuzo zombini iziphelo ukuze i-flange ilungelelaniswe ngokuchanekileyo kwaye kube lula ukuyifakela. Isihlalo serabha sifakwe ngokupheleleyo emzimbeni, siqinisekisa ukuba itywina liqinile, lihlala ixesha elide ngaphandle kwezixhobo zesihlalo ezahlukeneyo. Yenziwe ngokwe-API 609 / EN 593, ububanzi be-DN350–DN1200 (14″–48″), ukulinganiswa koxinzelelo lwe-PN10 / PN16 / PN25 kunye ne-ANSI Class 125/150. I-Nortech ngumvelisi kunye nomthengisi weevalvu zebhabhathane zohlobo lwe-U eTshayina.

Uyilo lweflange oludibeneyo lususa imfuneko yeeadaptha zeflange, lunciphisa ixesha lokufaka kunye nomngcipheko wokungahambi kakuhle - okubaluleke kakhulu kwiipayipi ezinkulu kwiindawo zamanzi, ukunkcenkceshela, kunye neenkqubo zenkqubo yemizi-mveliso. Umzimba kunye nediski ziyafumaneka kwisinyithi esithambileyo, intsimbi yekhabhoni, intsimbi engatyiwayo, kunye ne-alu-bronze ukuze zilungele imidiya erhabaxa okanye efuna ukubola. Izinto zesihlalo ziquka i-EPDM, i-NBR, i-FKM, kunye ne-silicone, ezigubungela uluhlu olubanzi lwamaqondo obushushu kunye neentlobo zolwelo. Iflange ephezulu ye-ISO 5211 iqinisekisa ukuhambelana ngqo nee-actuators zesandla, zombane, kunye neze-pneumatic. Zonke iivalvu ziyavavanywa kwaye zihlolwe kwi-API 598 / EN 12266.

Ivalvu yebhabhathane yohlobo lwe-U ephindwe kabini — Umboniso wentshayelelo

Yintoni iValve yeButterfly eneFlanged U-Type ephindwe kabini?

Iivalvu yebhabhathane yohlobo lwe-U ephindwe kabiniyivalvu yebhabhathane ehleli phantsi eqinileyo — ekwabizwa ngokuba yivalvu yebhabhathane "eyi-concentric", "eline-raber lined", okanye "ehleli phantsi-raber". Inesihlalo serabha esihlala phantsi esiqinileyo esifakwe ngqo emzimbeni, phakathi kobubanzi bangaphandle bediski kunye nodonga lwangaphakathi lwevalvu, ukuqinisekisa ukutywinwa okuthembekileyo okuqinileyo kwiintlobo ngeentlobo zezicelo.

Ivalvu ejika ikota ejikeleza i-90° ukuvula okanye ukuvala ukuhamba kolwelo ngokupheleleyo. Idiski ejikelezayo — efakwe embindini womzimba wevalvu — isebenza njengendlela yokuvala ephambili, eqhagamshelwe kwi-actuator okanye kwisibambo nge-shaft ephakathi. Xa idiski igqibezela ukujikeleza okupheleleyo kwe-90-degree, ivalvu isebenza njengeisivalo sokubekwa wedwaXa ivuliwe kancinci, isebenza njengeivalvu elawula ukuhamba kwamanzi, okuvumela ulawulo oluchanekileyo kwii-engile ezahlukeneyo zokuvula.

Ngokwendlela yokufakela, uhlobo lwe-U luhlelwa njengoivalvu yohlobo lwe-waferNangona ineeflange ezimbini ezidityanisiweyo eziphoswe emzimbeni, ubukhulu bayo bokujonga ubuso ngobuso bufana nohlobo oluqhelekileyo lwe-wafer — uyilo oluncinci, oluhambelana phakathi kweeflange ezimbini zepayipi ezinee-stud ezidlula ukusuka kwelinye icala ukuya kwelinye. Ivalvu ibanjwe endaweni yayo kwaye ivalwe zii-gasket phantsi koxinzelelo lwe-stud. Iiflange ezidityanisiweyo zenzelwe ngokukodwa ukunceda ukulungelelaniswa nokufakelwa, okwenza olu lungiselelo lube lolona khetho lukhethwayo kwiipayipi ezinkulu.

KwiNortech, iivalvu zebhabhathane ezihlala ziqinileyo ezikwimo ye-wafer kunye ne-lug zigubungela i-DN32–DN600. Kwiidayamitha ezinkulu, kusetyenziswa ivalvu yebhabhathane e-flanged yohlobo lwe-U — enika ulwakhiwo olufanayo oluqinisekisiweyo lwesihlalo esiqinileyo ngobukhulu be-DN350–DN1200 (14″–48″).

Itshati ye-CV/KV yevalvu yebhabhathane ehleli phantsi ehlala iqinile iyafumaneka xa iceliwe.

Uhlobo lwe-U vs. iWafer vs. iDouble Flanged— ezi ntlobo zintathu zokufakela zabelana ngolwakhiwo olufanayo oluhlala luqinile kodwa zahlukile kwindlela eziqhagamshela ngayo kumbhobho. Uthelekiso olungezantsi lubonisa umahluko ophambili kwindlela yoqhagamshelo lokugqibela kunye nendlela yokufakela.

DN350–DN1200 PN10 / PN16 / PN25 Iklasi ye-ANSI 125/150 Isihlalo serabha esivulcanized Ulungelelwaniso lweflegi edibeneyo Ilula kwaye ayidingi kugcinwa

Uthelekiso lokufakelwa kwevalvu yebhabhathane ehleli phantsi eqinileyo — uhlobo lwe-wafer, uhlobo lwe-U, uhlobo oluphindwe kabini
