Valve ebyiri z'ikinyugunyugu zikoresha amazi

Valve ya Nortech ifite uburebure bubiri bw'ikinyugunyugu ikoreshwa mu gukora amazi itanga uruziga rwizewe kandi rufite amashanyarazi make mu miyoboro minini. Uburyo bwa disiki ya offset bukuraho imiterere y'intebe ihoraho mu gihe cyo gukora, bikongera cyane igihe cyo kuyikoresha no kugabanya amashanyarazi ugereranije n'imiterere yayo. Iboneka muri DN350–DN2000 (14″–80″), izi valve zakozwe mu rwego rwo gutanga amazi mu mujyi, inganda zitunganya amazi, n'inganda nini zikora amazi.

Icupa ry'icyuma rikozwe mu cyuma hamwe na disiki ifite EPDM cyangwa NBR ishobora gusimburwa bitanga ubushobozi bwo gufunga igihe kirekire no koroshya kubungabunga urugo. Bikurikiza EN 593, API 609 na AWWA C504. Imbonankubone kuri ANSI B16.10, ISO 5752 Series 13/14, EN 558-1 Series 13/14. Impera y'icyuma kuri ASME B16.5, B16.47, AWWA C207, EN 1092-2. Byageragejwe kuri API 598. Igipimo cy'umuvuduko PN10/16/25, ANSI Class 150.

Nortech ni uruganda rukora kandi rugatanga ibikoresho by’ubururu binini bitagira ingano mu Bushinwa, rukora kandi rugatanga ibikoresho by’amazi n’inganda ku isi yose.

Ibisobanuro birambuye ku gicuruzwa

Ibirango by'ibicuruzwa

Valve y'ibinyugunyugu idafite imiterere ibiri — Urupapuro rw'ibicuruzwa

Valve y'ikinyugunyugu cya Double Eccentric ni iki?

Itsindavalve y'ibinyugunyugu ifite imiterere ibiri idasanzwe— izwi kandi nka valve y’ibinyugunyugu ifite imiterere ibiri — ifite imiterere yihariye ya disiki aho umugozi uva hagati ya disiki ndetse n’umurongo wo hagati w’umuyoboro. Iyi miterere ibiri ituma disiki iva ku ntebe ako kanya imaze gufungurwa, bigatuma idakomeza gukorana hagati ya disiki n’intebe mu gihe cyo gukora.

Ingaruka zabyo ni ukugabanuka cyane kwa torque yo gukora, kugabanuka kwangirika kw'intebe, no kumara igihe kirekire ugereranije na valve z'ibinyugunyugu zifatanye. Iyo ifunguye neza, disiki ntikora ku ntebe, bigatuma ubuso bufunga budahinduka mu gihe cy'amasaha ibihumbi n'ibihumbi.

Impeta yo gufunga ikozwe muri elastomer, ishyirwa muri disiki kandi ishyigikiwe n'icyuma gipfuka, ikora ubuso bukomeza kandi butaziguye bwo gufunga ku ruziga rwose. Iyi miterere itanga ubushobozi bwo gufunga bw'icyerekezo cy'imirongo ibiri kandi ikunze kugenwa ku miyoboro y'amazi yo mu mujyi, inganda zitunganya amazi, n'imiyoboro minini y'amazi.

Ikwiriye gukoreshwa mu gufunga mu cyerekezo kimwe no mu cyerekezo kibiri. Igipimo gisanzwe cy'umuvuduko ANSI Class 150 / PN10 / PN16 / PN25.

Igishushanyo mbonera cya kabiri gitandukanye— imiterere ya disiki ebyiri zisohokana bivuze ko kamera za disiki zigenda kure y’intebe nyuma yo gufungura dogere nke gusa, bikuraho ukugungana kw’intebe mu gihe cyose cyo guhagarara no kongera igihe cyo kwicara ugereranije n’imiterere y’intebe.

Nta mwanya ugeramo iyo ufunguye Umuvuduko muke wo gukora Gufunga mu cyerekezo cy'ibice bibiri DN350–DN2000 Ibikoresho by'amazi

Ibintu by'ingenzi bigize valve y'ibinyugunyugu ifite imiterere ibiri idasanzwe

Igihe kirekire cyo gukora — igishushanyo mbonera cya disiki irambitse

Umuvuduko uri kuri disiki urekurwa nyuma yo gufungura gake, bigagabanya kwangirika kw'ikimenyetso cya disiki. Igishushanyo mbonera cyayo kandi kigabanya gukandamizwa kw'intebe, bigatuma imbaraga zikora neza mu gihe cyose valve ikora.

Imiterere y'intebe z'impanga irahari

Igishushanyo mbonera cy’intebe gifite intebe y’icyuma ikozwe mu mashini kandi ipfutse epoxy ifatanye n’umubiri wayo. Igishushanyo mbonera cy’intebe y’icyuma kitagira umugese gitanga impeta y’intebe ishobora gusimburwa ifunze neza ifite impeta ya O kugira ngo hirindwe ko amazi yinjira munsi y’intebe y’intebe.

Igishushanyo cy'umugozi — gishobora gusimburwa n'umuvuduko

Gufunga umugozi bishobora gusimburwa neza iyo umuntu asunitswe n'igitutu, bigatuma byoroha kubungabunga umurima nta gufunga umurongo. Gufunga EPDM bifasha ko imbere hagumana ubukana; Gufunga NBR birinda imyanda yo hanze n'amazi yinjira.

Ifu ya disiki yakozwe neza kugira ngo ikore neza cyane

Imiterere y'ikizingo cya disiki igenzura uburyo gishyirwa mu mwanya neza kandi igakora neza. Ikizingo cya rubber cyiza cyane gituma ingano y'ikizingo igabanuka, bigatuma habaho imbaraga nke zo gufunga. Ikizingo cya EPDM cyemewe gukoreshwa mu mazi meza na ACS na WRAS.

Gufunga mu cyerekezo kimwe no mu cyerekezo kimwe biraboneka iyo ubisabye

Ifu isimburana kuri disiki ifite ubuso bukomeza gufunga

Igishushanyo mbonera cy'imyanya ibiri — intebe zangiritse kandi torque yayo igabanuka

Impeta yo gufunga ishobora kongera gukoreshwa igihe kirekire
