Gate Valve vs Globe Valve: Musiyano Mukuru, Mashandisirwo, uye Kuzivikanwa
Mapaipi emaindasitiri anoshandisa nzira chaiyo yekudzora kuyerera kwemvura, zvichiita kuti kusarudzwa kwemavharuvhu kuve kwakakosha. Mhando mbiri huru - mavharuvhu egedhi nemavharuvhu eglobe - anoshanda zvakasiyana pasinei nekufanana kwakafanana. Gwaro iri rinotsanangura kusiyana kwawo, mashandisirwo, uye nzira dzekuzivikanwa.
Chii chinonzi Gate Valve
Vharuvhu yegedhiinodzora kuyerera kwemvura nekusimudza kana kudzikisa "gedhi" rakaita serectangular kana rakaita sewedge kuburikidza nedanda rakarukwa. Zvinhu zvikuru:
Kushanda: Yakavhurika/yakavharwa chete; haina kukodzera kupwanywa.
Nzira Yekuyerera: Dhizaini yakanyatsogadzirwa inoderedza kuderera kwekumanikidzwa.
Kuvhara: Dzima zvakasimba kana yakavharwa zvizere, paine njodzi shoma yekubuda kwemvura.
Mashandisirwo: Makemikoro ePetrokemikari, mvura, mapaipi ane dhayamita hombe uko kudzivirira kuyerera kwemvura kushoma kwakakosha.
Muenzaniso:Munzvimbo dzemvura dzemumaguta, mavharuvhu egedhi anoparadzanisa zvikamu panguva yekugadzirisa nekuda kwekusakwanisa kuyerera kwemvura kana akavhurika.
Chii chinonzi Globe Valve
Vharuvhu yepasi rose(kana vharuvhu yekumisa) inodzora kufamba kwemhepo ichishandisa dhisiki kana chivharo chinodzvanya chakamira pachigaro. Zvinhu zvikuru:
Kushanda: Yakagadzirirwa kupwanya uye kushanda nguva nenguva.
Nzira Yekuyerera: Dunhu rakaita seS rinowedzera kuramba asi rinoita kuti ritonge nemazvo.
Kuvhara: Nzira yekumanikidza kuvhara inoda simba rakawanda rekuvhara.
Mashandisirwo: Maboiler, HVAC, masisitimu emhepo—chero mamiriro ezvinhu anoda kugadziriswa kwekuyerera kwemvura.
Muenzaniso: Mavharuvhu epasi anodzora kufamba kwemhepo muzviteshi zvemagetsi, zvichibvumira vashandisi kugadzirisa kumanikidzwa.
Kusiyana Kwakakosha: Gate Valve vs Globe Valve
| Chikamu | Vharuvhu yeGedhi | Vharuvhu Yepasi |
|---|---|---|
| Maumbirwo | Nzira yekuyerera yakatwasuka; gedhi rinosimuka rakamira | Nzira yekuyerera kweS; dhisiki inofamba yakatwasuka pachigaro |
| Basa | Kuvhura/kudzima chete; hapana kudzvanya | Kurovera nekubatidza/kudzima |
| Kuramba Kuyerera | Yakaderera zvikuru (kana yakavhurwa zvizere) | Yakakwira (nekuda kwekuchinja kwenzira) |
| Kureba kwehunde | Kureba (dhizaini yehunde inokwira) | Kapfupi |
| Kuiswa | Kuyerera kwenzira mbiri | Kutungamira (museve unoratidza nzira yekuyerera) |
Maitiro Ekuziva Mavharuvhu Egedhi & Mavharuvhu Epasi
1. Kuongorora Zvinoonekwa:
Vharuvhu yeGedhi: Muviri murefu (kunyanya mhando dzehunde dzinokwira); vhiri rinosimudzwa neruoko kana vharuvhu yavhurwa.
Vharuvhu yeGlobe: Muviri wakatenderera; kureba kwehunde kupfupi.
2. Kutungamirirwa kweKuyerera:
Mavharuvhu egedhi anotendera kuyerera kwenzira mbiri.
Mavharuvhu eglobe ane miseve yakananga yakakandwa pamusoro pemuviri.
3. Kushanda kwevhiri reruoko:
Mavharuvhu egedhi anoda kutenderera kakawanda kuti avhurwe/avharwe.
Mavharuvhu epasi anovhurika/kuvhara nekukurumidza (kufamba kwenguva pfupi kwetsinde).
Nguva Yokushandisa Valve Yega Yega
Sarudza Mavharuvhu Egedhi:
1. Kuvharwa kwemvura yakazara mumapaipi emvura/mafuta.
2. Masisitimu ekudonha kwesimba shoma (semuenzaniso, kutakura daro refu).
3. Kushanda nguva nenguva (semuenzaniso, kuvharwa kwemagetsi nekukurumidza).
Sarudza Mavharuvhu Epasi:
1. Kudzora kuyerera kwemvura (semuenzaniso, masisitimu ekutonhodza).
2. Kushanda nguva dzose (semuenzaniso, kugadzirisa zuva nezuva).
3. Kushandiswa kwemhepo ine simba guru remhepo/gasi.
Nei Kusarudza Valve Kuchikosha
Kusarudza vharuvhu risiri iro rinokonzera kusashanda zvakanaka kwesystem kana kutadza kushanda zvakanaka. Mavharuvhu egedhi anowedzera kuyerera munzvimbo dzakavhurika asi anodonhedza mvura kana akavharwa zvishoma. Mavharuvhu eglobe anopa kudzora asi anowedzera mari yesimba nekuda kwekusasimba. Gara uchienzanisa rudzi rwevharuvhu nezvinodiwa pakushanda—kuona kuchengetedzeka, kugara kwenguva refu, uye kushanda zvakanaka.
Zano reNyanzvi:Kune masisitimu ane simba guru, sanganisa mavharuvhu egedhi (main isolation) nemavharuvhu eglobe (precision control) kuti uwane mhedzisiro yakanaka.
