Gwaro Rekusarudza Valve Yemapaipi Emhepo: Zvinodiwa zveVharuvhu Yebhora & Mhando Dzakajairika
Masisitimu emhepo yemumaindasitiri anoda kusarudzwa kwemavharuvhu chaiwo kuti achengetedzeke uye ashande zvakanaka.Mavharuvhu ebhorashanda mumapaipi emhepo chete kana uchisangana nemamiriro ezvinhu akaomarara: kuramba kupisa kwakanyanya/kumanikidzwa, kuvharwa kwakasimba, uye magadzirirwo anoenderana nemhepo (semuenzaniso, mavharuvhu ebhora akavharwa zvizere). Heino tsananguro yehunyanzvi:
1. Zvinodiwa Zvakakosha zveSteam Ball Valve
◼ Zvishandiso & Maitiro Ekuvaka
- Zvinhu Zvinopisa Zvikuru: Mavharuvhu anoda ASTM A216 WCB simbi yakaumbwa kana yakaenzana nayo.
- Dhizaini yeFull-Bore: Inoita kuti kuyerera kwemvura kurege kudzorwa; kirasi yekumanikidzwa inofanira kuenderana nemapaipi (semuenzaniso, Kirasi 150 = 2.0MPa).
◼ Kushanda Kwekuvhara
- Zvisimbiso Zvakasimba Chete: Zvisimbiso zvakapfava zvinokundikana kana tembiricha yemhepo (>150°C).
- Kutenderera Kwakagadzikana: Magadzirirwo emabhora anoyangarara/asina kugadzika anofanira kuderedza kusakara.
◼ Maitiro Akanakisisa Ekushanda
- Kuisa Matavi Akamira: Inobvumira kukurumidza kuchinja 90° uye kudzivirira kubuda kwemvura.
◼ Nzira Dzakakosha Dzekudzivirira
- Mashandisirwo: Yakanakira kudzima/kugadzirisa steam nekukurumidza mumafuta, makemikari, uye magwenya emagetsi.
- Miganhu Yekuyerera: Kumhanya >40m/s kunokonzera kukurwa kwevhu - sarudza mamodheru zvichienderana nekuyerera kwepombi.
- Kugadzirisa: Ongorora zvisimbiso kota yega yega, bvisa mari yemukati, uye tevera nhungamiro dzeOEM.
2. Mavharuvhu matatu epamusoro eSteam Pipeline Akaenzaniswa
| Rudzi rweVharuvhu | Zvakanakira Zvikuru | Zvakanakira |
|---|---|---|
| Vharuvhu Yepasi | Kudzora kuyerera kwakarurama | Kudzora simba remhepo/kudzora simba remhepo |
| Vharuvhu yeGedhi | Kuvhara kusina kudonha kwemvura | Kuzviparadzanisa kwakazara nemhepo |
| Vharuvhu yeBhora | Kushanda nekukurumidza, dhizaini diki | Nzvimbo dzinogara dzichitasva mabhasikoro/dzisina nzvimbo yakawanda |
3. Zvinodiwa paVoltage yeSteam yeUniversal
Mavharuvhu ese emhepo anofanira kunge aine:
- Kuramba Kupisa Kwakanyanya: Kushanda kwenguva refu >150°C.
- Dziviriro yeKuora: Shandisa simbi isingasvibi ye316L pakupisa utsi.
- Zvisimbiso zveZero-Leakage: Zvinodzivirira kurasikirwa nesimba uye njodzi dzekuchengetedza.
4. Kutevedzera Mutemo uye Kusarudza Maitiro
- Makodhi Epasi Pose: Tevedzera API 600, ASME B16.34, DIN/EN pakugadzira/kuyedza.
- Maitiro Ekusarudza: Enzanisa zvirevo zvevharuvhu nekumanikidzwa kwepombi, tembiricha, mwero wekuyerera kwemvura, uye media.
- Kuiswa: Batisisa ANSI B31.1 kuti hurongwa hwemhepo huve hwakachengeteka.
Pfupiso:
Mavharuvhu ebhora akagadzirwa neglobe, gedhi, uye anoenderana nezvinodiwa ndizvo zvinonyanya kusarudzwa pamapaipi emhepo. Isa pamberi mavharuvhu ebhora akavharwa zvakasimba ane ASTM WCB bodies, simbisa mwero wekuyerera kwemvura (<40m/s), uye isa maitiro ekugadzirisa akajairwa.
