A216 WCB Yashizeho Icyuma Trunnion Yashizwe Kumupira

Intebe yicyicaro cyumupira uhamye ifite imiterere yihariye, ishobora kugera kumurongo wo hejuru. Intebe zombi za valve zirashobora gufungwa, ntihabeho kubuza gutembera mugihe cyo kwishyiriraho kandi ni byerekezo byombi.

Hariho ubwoko bubiri bwimiterere ya valve kumipira yumupira uhamye: ibice bibiri nibice bitatu. Ikibaho cyo hagati gihujwe na bolts, kandi kashe ikozwe muri polytetrafluoroethylene ikomejwe yashyizwe mu mpeta y'icyuma. Hano hari isoko yisoko yinyuma yicyuma kugirango umenye neza ko intebe ya valve irwanya umupira, ikomeza kashe. Byombi hejuru no hepfo ya valve ifite ibikoresho bya PTFE kugirango bigabanye guterana no kubika ibikorwa. Hasi ya shitingi ntoya ifite ibyapa byo guhinduranya kugirango umenye neza umupira hamwe nimpeta ifunga kumutwe. Bore yuzuye: Umuyoboro wa valve uhuza na diameter y'imbere y'umuyoboro wo gusukura imiyoboro.

- Ingano kuva 2 ”kugeza 24” (DN50mm kugeza DN600mm).

- Ibipimo byumuvuduko kuva mucyiciro 150LB kugeza 2500LB (PN10 kugeza PN142).

- Bore yuzuye cyangwa yagabanutse.

- Byoroheje bifunze cyangwa ibyuma bifunze.

- RF, RTJ cyangwa BW iherezo.

- Uburyo bwo gutwara bushobora kuba intoki, amashanyarazi, pneumatike.

Igishushanyo mbonera: API 608, API 6D, ASME B16.34

Ikirangantego cya Flange: ASME B16.5, ASME B16.47, ASME B16.25

Amaso imbonankubone: API 6D, ASME B16.10

Ikizamini cyikigereranyo: API 598

Ibyiza byo gukora ibyuma bya trunnion yashizwe kumupira wumupira kuva BOLON.

1.Imikorere mike

Umuzingi ushyigikiwe no hejuru no hepfo, kugabanya guterana no gukuraho umuriro mwinshi uterwa numutwaro munini wo gufunga watewe numuvuduko winjira usunika uruziga hamwe nicyicaro.

2.Imikorere yizewe

Impeta imwe ya kashe ya PTFE yashyizwe mu cyicaro cy’icyuma kitagira umwanda, kandi hashyirwaho isoko ku mpera yicyicaro cy’icyuma kugira ngo habeho imbaraga zihagije zo gufunga impeta. Iyo kashe ya valve yambarwa mugihe cyo kuyikoresha, valve ikomeza kwemeza neza imikorere yikimenyetso munsi yimvura.

3.Imiterere yumuriro

Mu rwego rwo gukumira ko habaho ubushyuhe butunguranye cyangwa umuriro, bishobora gutera impeta ya PTFE gutwika kandi bigatera kumeneka gukomeye, kandi bigateza imbere umuriro, hashyirwaho impeta yo gufunga umuriro hagati y’umuzingi n'intebe ya valve. Iyo impeta yo gufunga yatwitse, hifashishijwe imbaraga zimpeshyi, impeta yo gufunga intebe ya valve ihita isunikwa kumurongo, igakora icyuma kashe yicyuma kandi kigera kumurongo runaka wo gufunga. Ikizamini cyo kurwanya umuriro cyujuje ibisabwa bya APl6FA na APl607.

4.Igikorwa cyo gutabara byikora

Iyo umuvuduko wikigereranyo gihagaze mubyumba bya valve wiyongereye bidasanzwe kurenza imbaraga zambere yimpeshyi, intebe ya valve izasubira inyuma kandi itandukane numurima, bigere ku ngaruka zo kugabanya umuvuduko ukabije. Nyuma yo kugabanya umuvuduko, intebe ya valve izahita ikira

5.Igikorwa cyo gusukura imiyoboro

Imyobo yimyanda yashyizwe kumpande zombi zumubiri wa valve kugirango harebwe niba imyanda yatembye. Mugihe cyo gukora, iyo valve ifunguye neza cyangwa ifunze byuzuye, umuvuduko mubyumba byo hagati urashobora gukurwaho kandi gupakira birashobora gusimburwa muburyo butaziguye; Irashobora gusohora ibintu bisigaye mu cyumba cyo hagati kandi bikagabanya umwanda w’ibikoresho kuri valve.

6.Gufunga gutabara inshinge byihutirwa

Bitewe nibintu byamahanga mumashanyarazi cyangwa umuriro bitera kunanirwa kubwimpanuka ya kashe ya kashe ya valve, valve yamavuta itanga ihuza ryihuse nimbunda yamavuta, hamwe na pompe yatumijwe mumahanga byoroshye kandi byihuse itera amavuta yo gufunga ahantu hafungirwa intebe kugirango hagabanuke kumeneka.

7.Ikirangantego cyizewe kashe hamwe na torque ikora

Usibye gushyiraho impeta zisanzwe zifunga, O-impeta zashyizweho na glande yo gupakira, byemeza ko kashe ya valve ikingirwa hamwe na kashe ebyiri; Kwiyongera kubipfunyika bya grafite no gufunga amavuta bigabanya kugabanuka kumashanyarazi nyuma yumuriro. Kunyerera kunyerera hamwe no guterura ibiti bya valve bituma imikorere ya valve yoroshye.

8.Bore yuzuye cyangwa yagabanutse

Byuzuye bore cyangwa bigabanijwe bore irashobora gutoranywa nkuko bikenewe. Urujya n'uruza rw'amazi yuzuye ya bore yuzuye arahuza na diametre y'imbere y'umuyoboro, byoroshye gusukura umuyoboro.

9.Igiti cya valve kirashobora kwagurwa

Ukurikije kwishyiriraho cyangwa gukora ibisabwa, igiti cya valve kirashobora kwagurwa. Umuyoboro mugari wa valve, cyane cyane ubereye gaze yo mumijyi nibindi bihe bisaba gushyiramo imiyoboro yashyinguwe. Ingano yagutse ya stem yagenwe igomba kugenwa ukurikije ibyo abakiriya bakeneye.

10.Igikorwa cyoroshye

Gukoresha intebe hamwe nigitereko cyibiti hamwe na coefficient ntoya yo guterana hamwe nibintu byiza byo kwisiga bigabanya cyane urumuri rukora rwa valve. Kubwibyo, niyo udatanga amavuta yo gufunga, valve irashobora gukoreshwa muburyo bworoshye kandi mubwisanzure mugihe kirekire.
