Uburyo bwo kuvura ububiko bwa kashe ya valve Ese valve ikeneye gushiraho amahame ya bypass na Igenamiterere?

Kuramo ibimera neza kandi neza. Nibiba ngombwa, koresha umurongo wa torque. Preload igomba kuba yujuje ibisabwa kandi ntigomba kuba kinini cyangwa gito. Hagomba kubaho preload yemewe kumurongo wa flange numutwe. Iteraniro rya gaze rigomba guhuzwa hagati kandi imbaraga zigomba kuba zimwe. Igipapuro cyikariso hamwe nigituba kabiri ntibyemewe.
Impamvu:
1, gufunga hejuru gusya bitaringaniye, ntibishobora gukora umurongo wa hafi.
2. Isano iri hagati yuruti nigice cyo gufunga irahagarikwa, ntabwo igororotse cyangwa yambarwa.
3, igiti cya valve cyunamye cyangwa guterana ntabwo aribyo, kugirango igice cyo gufunga kigoramye cyangwa kitari hagati.
4. Guhitamo bidahwitse ubuziranenge bwibikoresho byo hejuru cyangwa kudahitamo valve ukurikije uko akazi gakorwa.
Uburyo bwo gukumira no kurandura:
1. Hitamo neza ibikoresho nubwoko bwa bouncing gasket ukurikije akazi.
2, guhindura neza, gukora neza.
3, igomba kuba iringaniye kandi igereranya Bolt, nibiba ngombwa, igomba gukoresha torque wrench, preload igomba kuba yujuje ibisabwa, ntabwo ari binini cyangwa bito. Hagomba kubaho preload yemewe kumurongo wa flange numutwe.
4, igiterane cya gasketi kigomba guhuzwa, imbaraga zisa, lap gaze no gukoresha gasketi ebyiri ntabwo byemewe.
5, gufunga static kwangirika kwangirika, gutunganya ibyangiritse, ubwiza bwo gutunganya ntabwo buri hejuru, bigomba gusanwa, gusya, kugenzura amabara, gukora ubuso buhamye bujuje ibyangombwa bisabwa.
6. Mugihe ushyiraho gaze, hagomba kwitonderwa isuku, hejuru yikimenyetso hagomba kuba kerosene, kandi gasike ntigomba kugwa hasi.
Ese valve ikeneye gushiraho amahame ya bypass na Igenamiterere? Rimwe na rimwe tubona indangagaciro nini ugereranije mu miyoboro imwe n'imwe, kandi burigihe hariho bypass by valve yashizwemo. Kuki ibi? Ni ubuhe butumwa bukuru? Ni ibihe bihe bigomba gushyirwaho? Ni ubuhe burebure bwa valve ya bypass y'ibikoresho bijyanye? Mubyukuri, bypass ya valve yashyizwe mumurongo, kandi uruhare rwayo rushobora kugabanywamo ibice bibiri muri rusange: kimwe nukugira uruhare mukurinda (igitutu kiringaniye kumpande zombi), ikindi nikibazo cyihutirwa!

Ubwa mbere, ingaruka zo gukingira, zishobora nanone kuvugwa ko ari igipimo cyo gukingira icyuma gikuru, kugirango wirinde valve mbere na nyuma yo gutandukanya umuvuduko ni munini cyane, kandi bigatera kwihanganira gufungura, valve ntabwo ari nziza gufungura, cyane cyane muri bamwe kalibiri nini cyangwa umuyoboro mwinshi. Mbere yo gufungura umuyoboro mwinshi unyuze mumashanyarazi ya bypass, kugirango wirinde umuvuduko mwinshi utunguranye, gushiraho ingaruka kumuyoboro uri munsi ya valve. Cyangwa itandukaniro ryumuvuduko hagati yimpande zombi za valve nini cyane, urumuri rufungura ni runini cyane, kugirango wirinde kwangirika kwumuriro kuri valve, kurenga umuvuduko ukabije mbere yo gufungura valve.
Icya kabiri, uruhare rwihutirwa, nkumuyoboro uhagaze kugirango ukoreshe, inyungu nini nuko iyo mugihe nyamukuru ya valve yananiwe, cyangwa gukenera kubungabungwa no kuvugurura, ushobora gufungura umuzenguruko wa valve, kandi ntibigire ingaruka kumusaruro usanzwe.
Niba valve ikeneye gushyirwaho na bypass valve ibisabwa byihariye na Igenamiterere* kubisobanuro)
Icyiciro cya 2.5mpa, DN400 cyangwa hejuru; Icyiciro cya 4.0mpa, DN250 cyangwa hejuru; 6.4mpa amanota, DN200 cyangwa hejuru; Icyiciro cya 10MPa, DN150 cyangwa hejuru;
DN100 ~ DN200 valve, umuyoboro wa bypass na bypass ya DN20; DN250 ~ DN600 valve, umuyoboro wa bypass na bypass ya DN25; Kuri valve hejuru ya DN600, umuyoboro wa bypass na bypass valve ni DN40.
