Kodi Valavu ya Chipata cha NRS ndi Chiyani?
NRS (Sinthani Yokwera)mavavu a chipataIli ndi tsinde lomwe limazungulira pamalo pake pamene likugwiritsidwa ntchito—tsinde silimayenda mmwamba kapena pansi kunja pamene valavu ikutsegulidwa kapena kutsekedwa.
Zinthu Zofunika Kwambiri:
- ①Theulusi wa tsinde uli mkati mwa thupi la valavu, ikakhudzana ndi madzi.
- ②Kapangidwe kakang'ono—koyenera kwambirimalo opapatizakapena kukhazikitsa pansi pa nthaka.
- ③Amagwiritsidwa ntchito kwambirimakina amadzi a m'boma, kuthirira, ndi mipope ya madzi ozimitsa moto.
Zoganizira:
- ①Themalo a valavu sakuonekakunja—muyenera kudalira chizindikiro cha malo kapena kukumbukira.
- ②Popeza tsinde limawonekera ku media mkati mwa valavu,dzimbiriikhoza kukhala vuto lokonza zinthu m'malo ena.
Kodi Valavu ya Chipata cha OS&Y ndi Chiyani?
Ma valve a chipata cha OS&Y (Outside Screw and Yoke) ali ndi tsinde lomwe limakwera ndi kutsika moonekera pamene gudumu lamanja likuzunguliridwa. Ulusiwo uli kunja kwa thupi la valavu, wopatukana ndi madzi.
Zinthu Zofunika Kwambiri:
- ①TheMalo a valavu ndi osavuta kuwona—ngati tsinde lili mmwamba, valavu imatsegulidwa; ngati lili pansi, imatsekedwa.
- ②Thunthu la mtengowu limatetezedwa ku zinthu zobisika, zomwe zimachepetsa mwayi woti dzimbiri lizibwera.
- ③ Amafunika kwa ambirimiyezo yoteteza moto(NFPA) ya makina opopera moto.
Zoganizira:
- ①Imafuna malo oimirira kuti igwirizane ndi tsinde lokwera.
- ② Amagwiritsidwa ntchito nthawi zambiripamwamba pa nthaka, m'zipinda zamakanika, kapena komwe kumafunika kutsimikizira kowoneka bwino.
NRS VS OS&Y: Kuyerekeza Mbali ndi Mbali
| Mbali | Valavu ya Chipata cha NRS | Valavu ya Chipata cha OS&Y |
|---|---|---|
| Kusuntha kwa Tsinde | Zamkati, sizimakwera | Kunja, tsinde limakwera pamene valavu ikutseguka |
| Chizindikiro cha Malo Owonekera | No | Inde |
| Kufunika kwa Malo | Yaing'ono, yabwino kwambiri pansi pa nthaka | Imafuna chilolezo choyimirira |
| Kukana Kudzikundikira | Chosavuta kukhudzidwa (tsinde limakhudza madzi) | Chitetezo chabwino (chochotsedwa pa tsinde) |
| Mlandu Woyenera Kugwiritsa Ntchito | Mapaipi amadzi apansi panthaka, ma hydrant | Makina opopera moto, zipinda zamakanika |
| Kugwiritsa Ntchito Chitetezo cha Moto | NFPA siilimbikitsa kugwiritsa ntchito makina ozimitsa moto | Muyezo wosankhidwa ndi NFPA pamakina ozimitsa moto |
| Kukonza | Zovuta pang'ono kuziyang'ana kapena kukonza | Zosavuta kuziyang'ana ndi kuzisamalira |
Kodi ma valve a OS&Y ndi NRS amagwiritsidwa ntchito bwanji nthawi zambiri?
Ma Valves a Chipata cha NRS
- ①Mapaipi operekera madzi pansi pa nthaka
- ②Kudzipatula kwa madzi
- ③Makina othirira
- ④Machitidwe a mafakitale okhala ndi malo ochepa
Ma Vavulovu a Chipata cha OS&Y
- ①Makina opopera moto (otsatira malamulo a NFPA)
- ②Zipinda za injini za m'madzi
- ③Mafakitale oyeretsera ndi mafakitale a mankhwala
- ④Malo oyeretsera madzi
Chifukwa Chake Ndi Chofunika Mu Ntchito Zapamadzi ndi Moto
- ①Poteteza moto, kutsimikizira kowoneka bwino ndikofunikira kwambiri—ma valve a OS&Y ndi omwe amakondedwa.
- ②Mu machitidwe a m'nyanja, komwe malo ndi ochepa ndipo mikhalidwe ndi yovuta, mavavu a NRS angakhale oyenera, koma amafunikira zipangizo zosagwira dzimbiri.
