Chii chinonzi NRS Gate Valve
NRS (Simba Risingakwiri)mavharuvhu egedhiine dzinde rinotenderera panzvimbo paro parinoshandiswa—dzinde harifambe kumusoro kana pasi kunze sezvo vharuvhu inovhurwa kana kuvharwa.
Zvinhu Zvikuru:
- ①Izvoshinda dzesimbi dziri mukati memuviri wevharuvhu, kana yasangana nemvura.
- ②Dhizaini diki—yakanakiranzvimbo dzakamanikanakana kuiswa pasi pevhu.
- ③Inowanzo shandiswa mumasisitimu emvura emakanzuru, kudiridza, uye migero yemvura inodzima moto.
Zvaunofanira Kufunga nezvazvo:
- ①Izvonzvimbo yevharuvhu haionekwekunze—unofanira kuvimba nechinongedzo chenzvimbo kana ndangariro.
- ②Sezvo tsinde iri pachena kune zviri mukati mevharuvhu,ngurainogona kuva dambudziko rekugadzirisa munzvimbo dzakati wandei.
Chii chinonzi OS&Y Gate Valve
Mavharuvhu epagedhi eOS&Y (Outside Screw and Yoke) ane tsinde rinokwira nekudzika zvinooneka kana vhiri reruoko richitenderedzwa. Mashinda acho ari kunze kwemuviri wevharuvhu, akaparadzaniswa nemvura.
Zvinhu Zvikuru:
- ①Izvonzvimbo yevharuvhu iri nyore kuona—kana tsinde iri mudenga, vharuvhu yakavhurika; kana iri pasi, yakavharwa.
- ②Hunde yacho yakachengetedzwa kubva kune zvinosvibisa, zvichideredza mukana wekuora.
- ③Zvinodiwa nevakawandamitemo yekudzivirira moto(NFPA) yemasisitimu ekupfapfaidza moto.
Zvaunofanira Kufunga nezvazvo:
- ①Inoda nzvimbo yakareba yakatwasuka kuti ikwane tsinde rinokwira.
- ②Inowanzo shandiswapamusoro pevhu, mumakamuri emakanika, kana kuti panodiwa kusimbiswa nemaziso.
NRS VS OS&Y: Kuenzanisa Padivi Nepadivi
| Chinhu | Vharuvhu yeGedhi reNRS | Vharuvhu yeSuo reOS&Y |
|---|---|---|
| Kufamba kweHunde | Yemukati, haimuki | Kunze, tsinde rinosimuka sezvo vharuvhu rinovhurwa |
| Chiratidzo cheChinzvimbo Chinoonekwa | No | Ehe |
| Kudiwa Kwenzvimbo | Yakabatana, zviri nani kushandisa pasi pevhu | Inoda nzvimbo yakamira |
| Kuramba Kuora | Zviri nyore kubatwa nechirwere (stem contact fluid) | Dziviriro iri nani (yakabviswa tsinde) |
| Nyaya Yakakodzera Yekushandisa | Mapombi emvura epasi pevhu, mapombi emvura | Masisitimu ekupfapfaidza moto, makamuri emakanika |
| Kushandiswa kweDziviriro yeMoto | Hazvikurudzirwi neNFPA kumasystem emoto | Mwero unodiwa neNFPA wezvirongwa zvemoto |
| Kugadzirisa | Zvakanyanya kuoma kuongorora kana kugadzirisa | Zviri nyore kuongorora nekutarisa uye kugadzirisa |
Mavharuvhu eOS&Y neNRS anowanzo shandiswa kupi?
Mavharuvhu eGedhi reNRS
- ①Mapaipi emvura ari pasi pevhu
- ②Kuzviparadzanisa nemvura
- ③Maitiro ekudiridza
- ④Masisitimu emaindasitiri ane nzvimbo shoma
Mavharuvhu eSuo reOS&Y
- ①Masisitimu ekupfapfaidza moto (anoenderana neNFPA)
- ②Makamuri einjini dzemugungwa
- ③Mafekitori ekuchenesa nemakemikari
- ④Nzvimbo dzekuchenesa mvura
Nei Zvichikosha Mukushandiswa Kwemvura Nemoto
- ①Mukudzivirira moto, kusimbiswa kwemaziso kwakakosha—mavharuvhu eOS&Y ndiwo anofarirwa.
- ②Munzvimbo dzemugungwa, uko nzvimbo iri shoma uye mamiriro ezvinhu akaoma, mavharuvhu eNRS anogona kunge akakodzera, asi anoda zvinhu zvinodzivirira ngura.
