I-U Type Butterfly Valve

Isithombe Esifakiwe Sevalvu Yebhabhathane Yohlobo lwe-U

Incazelo emfushane:

Iivalvu yebhabhathane yohlobo lwe-U ephindwe kabiliIsakhiwo esifanayo esiqinile esihlala phansi njengohlobo lwe-wafer, kodwa inama-flange ahlanganisiwe kuzo zombili izinhlangothi ukuze kulungiswe kahle i-flange futhi kube lula ukufakwa. Isihlalo serabha sihlanganiswe ngokuphelele emzimbeni, siqinisekisa ukuvalwa okuqinile, okuhlala isikhathi eside ngaphandle kwezingxenye zesihlalo ezihlukene. Kwenziwe ngokwe-API 609 / EN 593, ububanzi bosayizi DN350–DN1200 (14″–48″), izilinganiso zokucindezela PN10 / PN16 / PN25 kanye ne-ANSI Class 125/150. I-Nortech ingumkhiqizi nomhlinzeki we-valve ye-butterfly yohlobo lwe-U ehamba phambili eShayina.

Umklamo we-flange ohlanganisiwe uqeda isidingo sama-adapter e-flange, kunciphisa isikhathi sokufakwa kanye nengozi yokungahambisani kahle - okubaluleke kakhulu kumapayipi amakhulu obubanzi emisebenzini yamanzi, ekuniseleni, nasezinhlelweni zezinqubo zezimboni. Umzimba kanye nediski kuyatholakala ngensimbi ethambile, insimbi yekhabhoni, insimbi engagqwali, kanye nethusi le-alu ukuze kufanelane nemidiya ebolile noma edinga amandla. Izinto zesihlalo zifaka i-EPDM, i-NBR, i-FKM, kanye ne-silicone, ezimboza amazinga okushisa ahlukahlukene kanye nezinhlobo zoketshezi. I-flange ephezulu ye-ISO 5211 iqinisekisa ukuhambisana ngqo nama-actuator esandla, kagesi, kanye ne-pneumatic. Wonke ama-valve ahlolwa futhi ahlolwe ku-API 598 / EN 12266.

Ivalvu Yebhabhathane Ephindwe Kabili Ene-U Type — Ukubuka Ngaphambili Kwesingeniso

Iyini i-Double Flanged U-Type Butterfly Valve?

Iivalvu yebhabhathane yohlobo lwe-U ephindwe kabiliiyivalvu yebhabhathane ehlala iqinile — ebizwa nangokuthi ivalvu yebhabhathane "eyi-concentric", "ene-raber lined", noma "eye-raber seated". Inesihlalo serabha esiqinile esivundisiwe ngqo emzimbeni, phakathi kobubanzi bangaphandle bediski nodonga lwangaphakathi lwevalvu, okuqinisekisa ukuvalwa okuthembekile okuqinile kwe-bubble kuzo zonke izinhlelo zokusebenza.

Ivalvu yokujika ngekota ejikeleza ama-90° ukuvula noma ukuvala ukugeleza koketshezi ngokugcwele. Idiski eyindilinga — efakwe maphakathi nomzimba wevalvu — isebenza njengendlela yokuvala eyinhloko, exhunywe ku-actuator noma isibambo ngeshafti ephakathi. Lapho idiski iqeda ukujikeleza okugcwele kwama-90°, ivalvu isebenza njengeivalvu yokuzihlukanisaUma ivuliwe kancane, isebenza njenge-ivalvu yokulawula ukugeleza, okuvumela ukulawula okunembile kuma-engeli ahlukahlukene okuvula.

Ngokuphathelene nendlela yokufaka, uhlobo lwe-U luhlukaniswa njenge-ivalvu yohlobo lwe-waferNakuba inama-flange amabili ahlanganisiwe afakwe emzimbeni, ubukhulu bawo bobuso nobuso bufana nohlobo lwe-wafer olujwayelekile — luncane ngokwakhiwa, lufakwa phakathi kwama-flange amabili epayipi anama-stud adlula kusukela kolunye uhlangothi kuya kolunye. I-valve ibanjwe endaweni futhi ivalwe ngama-gasket ngaphansi kokucindezeleka kwe-stud. Ama-flange ahlanganisiwe aklanyelwe ngqo ukusiza ukuvumelanisa nokufakwa, okwenza lokhu kulungiselelwa kube ukukhetha okuthandwayo kosayizi bamapayipi amakhulu.

KwaNortech, amavalvu ebhabhathane ahlala eqinile anombala we-wafer kanye nohlobo lwe-lug amboza i-DN32–DN600. Kuma-diameter amakhulu, kusetshenziswa ivalvu yebhabhathane enombala we-U — enikeza ukwakhiwa okufanayo kwesihlalo esiqinile esiqinisekisiwe ngobukhulu be-DN350–DN1200 (14″–48″).

Ishadi le-CV/KV lohlobo lwe-U lwe-butterfly valve ehlala iqinile liyatholakala uma ulicela.

Uhlobo lwe-U vs. i-Wafer vs. i-Double Flanged— izinhlobo ezintathu zokufaka zabelana ngokwakhiwa okufanayo kwesihlalo esiqinile kodwa ziyahlukahluka endleleni ezixhuma ngayo epayipini. Ukuqhathanisa okungezansi kukhombisa umehluko obalulekile ekuxhumekeni kokugcina kanye nendlela yokufaka.

DN350–DN1200 I-PN10 / PN16 / PN25 Isigaba se-ANSI 125/150 Isihlalo senjoloba esivuvukile Ukulungiswa kwe-flange ehlanganisiwe Ilula futhi ayidingi ukulungiswa

Ukuqhathaniswa kokufakwa kwevalvu yebhabhathane ehlezi kahle — uhlobo lwe-wafer, uhlobo lwe-U, uhlobo oluphindwe kabili

Ukuqhathaniswa kokufakwa: uhlobo lwe-wafer / uhlobo lwe-U / uhlobo oluphindwe kabili

Umklamo wediski ongenaphini — ususa izindlela zokuvuza kudiski

I-ISO 5211 top flange — ukwenza ngokuzenzakalelayo okulula kanye nokulungiswa kabusha kwe-actuator

I-torque yokusebenza ephansi — ukukhetha i-actuator engabizi kakhulu

Amabheringi afakwe i-PTFE — awadingi ukulungiswa, akukho ukuthambisa okudingekayo

I-liner efakiwe — kulula ukuyishintsha, ayigqwali umzimba, ifanelekela isevisi yokuphela komugqa

Ama-flange ahlanganisiwe — enza kube lula ukuhambisana kahle nokufakwa kwama-valve amakhulu

Umbono womkhiqizo we-valve yebhabhathane ehleli kahle yohlobo lwe-U
