Uburyo bwo kubika ibikoresho byo gupakira:

Abuzuza uyu mushinga bigizwe ahanini nibikoresho bibiri bikurikira: PTFE na grafite yoroshye.

Iyo bibitswe, bifunze mumufuka cyangwa agasanduku. Bika neza mububiko bwumye kandi buhumeka, irinde izuba. Witondere guhumeka mugihe cyo kubika igihe kirekire, kandi ugenzure ubushyuhe bwaho butarenga 50 ° C kugirango wirinde ivumbi ryinshi. Niba umukungugu ufatanye hejuru yuwuzuza ukuweho ugakoreshwa, uhanagure umwenda usukuye.

Uburyo bwo gusimbuza Valve:

Kashe yo gupakira igizwe kuburyo bukurikira: 1) Gupakira ibinyomoro byo guhunika, 2) Swing bolt, 3) pin ihamye, 4) Gupakira, 5) Gupakira amaboko, 6) Gupakira isahani yumuvuduko (rimwe na rimwe 5 na 6 nibice bigize ibice ukurikije imiterere kandi bigenwa nuburyo butandukanye bwakazi, imikorere rusange ni kimwe no gutandukana)

Gupakira kashe yo gusimbuza intambwe nuburyo bukurikira:

1. Koresha umugozi kugirango ukureho 1) ibinyomoro byo gupakira hanyuma ubizamure 5) igikapu cyo gupakira hamwe na 6) icyapa cyo gupakira, usige umwanya wo gukora cyo gusimbuza ibipaki.

2. Koresha icyuma gisya cyangwa ikindi cyuma gikuramo ibyuma kugirango ukureho ibipapuro byumwimerere hanyuma ubisimbuze ikindi gishya. Niba gupakira bipfunyitse bikoreshwa, mugihe ushyiraho ibipapuro bishya, witondere ko icyerekezo cyo kugabanya gupakira kigomba guhindagurika kuri 90 ~ 180 °, kandi impande zirimo zigomba gusubirwamo kubiri. Ntugire inshuro nyinshi mu cyerekezo kimwe nkuko bigaragara ku gishushanyo;

3. Nyuma yo gushiraho igipimo gikwiye cyo gupakira, subiza 5) gupakira gland na 6) gushiraho icyapa. Mugihe ushyiraho, witondere umwanya wikidodo cyo gupakira hamwe na 6 ~ 10mm zimbitse mubipfundikizo (cyangwa inshuro 1.5 ~ 2 zububiko bwo gupakira) nkibisobanuro byerekana (Nkuko bigaragara hano).

4. Kugarura 1). Gupakira ibinyomoro, 2) Komeza umwanya wo kwishyiriraho hamwe kugeza bigeze kuri 20% yo gupakira.

5. Nyuma yo kurangiza intambwe yavuzwe haruguru, kora ubugenzuzi bwingenzi kuri valve yasimbuye paki mugukoresha ubutaha kugirango urebe niba ari ngombwa kongera preload yipakira.

Ijambo: Amabwiriza yo kongera gukomera no gusimbuza paki munsi yigitutu.

Ibikorwa bikurikira nibikorwa biteje akaga. Nyamuneka ntugerageze byoroshye niba bidakenewe. Nyamuneka nyamuneka ukurikize neza iyi nyandiko yubuyobozi mugihe cyibikorwa:

1. Umukoresha agomba kumva neza imashini na valve. Usibye ibikoresho bya mashini bikenewe, uyikoresha agomba kwambara uturindantoki twinshi, ingabo zo mu maso, n'ingofero.

2. Umuyoboro wafunguye neza kugeza kashe yo hejuru ya valve ikora neza. Ishingiro ryurubanza nuko imikorere yimikorere ya valve idashobora kongera kuzamura uruti rwa valve, kandi nta jwi ridasanzwe kuruti rwa valve.

3. Umukoresha agomba kuba kuruhande rwikimenyetso cyo gupakira cyangwa indi myanya idashobora gutegurwa. Birabujijwe rwose guhangana nu mwanya wo gupakira. Mugihe ipaki igomba gukenera, koresha umugozi kugirango ushimangire 1) Gupakira ibinyomoro byo guhunika, amenyo 2 ~ 4, impande zombi zipakurura compression Birakenewe gukorwa, ntabwo ari uruhande rumwe gusa.

4. Mugihe ipaki igomba gusimburwa, koresha umugozi kugirango urekure 1) Gupakira ibinyomoro byo guhunika, amenyo 2 ~ 4, ibinyomoro byo gupakira kumpande zombi bigomba gukorwa muburyo butandukanye. Muri iki gihe, niba hari igisubizo kidasanzwe kiva kumurongo wa valve, hita uhagarara hanyuma usubize ibinyomoro, komeza Ukoreshe uburyo bwo gukora valve ukurikije inzira yo muntambwe ya 2, uzuza kashe kumurongo wa valve kugeza igihe bizakorwa neza, hanyuma ukomeze gusimbuza ibipaki. Gupakira gusimbuza igitutu ntabwo byemewe gusimburwa rwose usibye ibihe bidasanzwe. Ingano yo gusimbuza ni 1/3 cya paki zose. Niba bidashoboka gucira urubanza, ibintu bitatu byambere birashobora gusimburwa. Nyuma yo kwishyiriraho birangiye, subiza iyinjizamo rya paki 5 yo gupakira hamwe na plaque 6 yo gupakira. Mugihe ushyiraho, witondere umwanya wikimenyetso cyo gupakira hamwe na 6 ~ 10mm zimbitse mubipfundikizo (cyangwa inshuro 1.5 ~ 2 z'ubugari bwa paki) nkibisobanuro byerekana. Kugarura 1). Gupakira ibinyomoro byo guhunika, 2) Komeza umwanya wo kwishyiriraho hamwe na 25% bya compression yo gupakira. Niba nta kumeneka kwimbere ya valve igipakira, iruzuye. Niba haribisohoka, kurikiza inzira murwego rwa 2 na 3 kugirango ukomere.

5. Intambwe zose zavuzwe haruguru ni izamuka ryizamuka ryikibaho nka: kuzamuka kumarembo yikibaho, kuzamuka kwihagararaho, nibindi, ntibikoreshwa kumurongo wijimye no kudazamura ibiti nka: irembo ryijimye ryijimye, umwijima igiti gihagarara, ikinyugunyugu, imipira yumupira nibindi.
