China U Type Butterfly Valve fekitari nevagadziri

Vharuvhu yeU Type Butterfly

Tsananguro pfupi:

Iyovharuvhu yeshavishavi yeU-mhando ine flange mbiriChigaro cherabha chakagadzirwa zvakafanana newafer, asi chine maflange akabatana kumativi ese maviri kuti chigadziriswe zvakanaka uye zvive nyore kuisa. Chigaro cherabha chakanyatsoiswa zvakananga mumuviri, zvichiita kuti chisimbiso chakasimba, chigare chisina zvikamu zvechigaro zvakasiyana. Chakagadzirwa zvinoenderana neAPI 609 / EN 593, saizi DN350–DN1200 (14″–48″), kumanikidzwa kwacho PN10 / PN16 / PN25 uye ANSI Class 125/150. Nortech ikambani inotungamira mukugadzira uye kutengesa mavharuvhu emhando yeU-type butterfly muChina.

Dhizaini yeflange inobatanidza inobvisa kudiwa kwema adapter eflange, zvichideredza nguva yekuisa uye njodzi yekusarongeka zvakanaka - zvinonyanya kukosha kumapaipi ane dhayamita hombe mumabasa emvura, kudiridza, uye masisitimu ekushanda kwemaindasitiri. Muviri nedhisiki zvinowanikwa musimbi yakapfava, simbi yekabhoni, simbi isingatsvedzeri, uye alu-bronze kuti zvienderane nemidziyo inoparadza kana inoda simba. Zvigaro zvinosanganisira EPDM, NBR, FKM, uye silicone, zvichifukidza tembiricha dzakasiyana siyana uye mhando dzemvura. ISO 5211 flange yepamusoro inoita kuti ienderane zvakananga nema actuators emaoko, emagetsi, uye epneumatic. Mavharuvhu ese anoedzwa uye anoongororwa zvichienderana neAPI 598 / EN 12266.

Vharuvhu yeButterfly ine Flanged U-Type Double — Intro Preview

Chii chinonzi Double Flanged U-Type Butterfly Valve?

Iyovharuvhu yeshavishavi yeU-mhando ine flange mbiriivharuvhu remashavishavi rakagara zvakanaka — rinonziwo vharuvhu remashavishavi rakagara zvakanaka re "concentric", "rabber lined", kana kuti "rabber seated". Rine chigaro cherabha chakagara zvakanaka chakasungirirwa zvakananga mumuviri, pakati pedhayamita rekunze redhisiki nemadziro emukati mevharuvhu, zvichiita kuti chivharo chakasimba chivhariswe zvakanaka munzvimbo dzakasiyana-siyana.

Vharuvhu inotenderera nekota inotenderera 90° kuti ivhure kana kuvhara kuyerera kwemvura zvizere. Dhisiki rakatenderera — rakaiswa pakati pemuviri wevharuvhu — rinoshanda senzira huru yekuvhara, yakabatana neactuator kana mubato kuburikidza nepakati peshaft. Kana dhisiki rapedza kutenderera kwese kwemadhigirii 90, vharuvhu inoshanda sevharuvhu yokuparadzanisaKana yakavhurika zvishoma, inoshanda sevharuvhu inodzora kuyerera, zvichibvumira kudzora kwakarurama pamakona akasiyana-siyana ekuvhura.

Panyaya yenzira yekuisa, mhando yeU inorongwa sevharuvhu yerudzi rwewaferKunyangwe iine maflange maviri akabatanidzwa akaiswa pamuviri, saizi yayo yekutarisana yakaenzana neyemhando yewafer yakajairika - yakagadzirwa zvishoma, ichikwana pakati pemaflange maviri epaipi ane mastuds anopfuura nepakati kubva kune rumwe rutivi kuenda kune rumwe. Vharuvhu inobatwa panzvimbo uye yakavharwa nemagaskets pasi pekumanikidzwa kwestud. Maflange akabatanidzwa akagadzirirwa kubatsira kurongeka uye kuiswa, zvichiita kuti iyi ive sarudzo inofarirwa kune saizi huru dzepaipi.

KuNortech, mavharuvhu eshavishavi akasimba ane mhando yewafer uye mavharuvhu emhando yelug anofukidza DN32–DN600. Kune dhayamita hombe, vharuvhu yeshavishavi ine mhando yeU inoshandiswa — ichipa chivakwa chakafanana chezvigaro zvinosimba zvine saizi DN350–DN1200 (14″–48″).

Chati yeCV/KV yevharuvhu reshavishavi rakagara zvakanaka reU-type inowanikwa kana ukaikumbira.

Rudzi rweU-Type vs. Wafer vs. Yakaputirwa Nemaflanges Maviri— mhando nhatu dzekuisa dzine chimiro chakafanana chekugara asi dzakasiyana pakubatanidza kwadzinoita nepaipi. Kuenzanisa kuri pazasi kunoratidza musiyano mukuru mukubatanidza kwekupedzisira nenzira yekuisa.

DN350–DN1200 PN10 / PN16 / PN25 Kirasi yeANSI 125/150 Chigaro cherabha chakaputirwa Kurongeka kweflange yakabatana Haisi kureruka uye haina kugadziriswa

Kuenzanisa kwekuisa vharuvhu yeshavishavi inogara yakasimba — mhando yewafer, mhando yeU, mhando ine flange mbiri

Kuenzanisa kwekuisa: wafer type / U-type / double flanged type

Vharuvhu yeU-Type Butterfly — Huru Hunhu Hwokutanga

Zvinhu zvikuru zvevharuvhu reshavishavi rakagara zvakanaka reU

Kuvaka kudiki — huremu hushoma, nzvimbo shoma yekuchengetera zvinhu uye nzvimbo yekuisa

Mugodhi wepakati, 100% chisimbiso chakasimba chebubble-tight, chero nzira yekuisa

Muviri wese une chibooreso — kuramba kuyerera kwemvura kwakaderera

Nzira yekuyerera isina maburi — iri nyore kuchenesa uye kuuraya utachiona, yakakodzera mvura yekunwa

Muviri wakaputirwa nerabha — mvura haimbobati muviri wesimbi

Dhizaini yedhisiki isina pin — inobvisa nzira dzekubuda kwemvura padhisiki

ISO 5211 flange yepamusoro - otomatiki iri nyore uye kugadzirisa actuator

Torque inoshanda zvishoma — sarudzo yeactuator isingadhuri

Mabheringi ane PTFE — haana kugadziriswa, hapana mafuta anodiwa

Mudziyo wakaiswa — uri nyore kutsiva, hauna ngura yemuviri, wakakodzera kushandiswa pakupera kwemutsara

Maflange akabatanidzwa — anorerutsa kurongeka kwakarurama uye kuiswa kwemavharuvhu ane dhayamita hombe

Vharuvhu reshavishavi rakagara zvakasimba rine U-type chigadzirwa chinoratidzwa
