Chii chinonzi Pneumatic Actuator Ball Valve
A vharafu yebhora remagetsi rinoshandisa simba remhepomudziyo unodzora kuyerera kwemvura unobatanidza vharuvhu yebhora neactuator yepneumatic kuti iite otomatiki yekudzora kwemvura, magasi, kana utsi mumasisitimu emaindasitiri. Chinyorwa chino chinotsanangura zvikamu zvayo, mhando, zvakanakira, uye kuti chakasiyana sei nedzimwe mhando dzevharuvhu.
Chii chinonzi Pneumatic Actuator
A actuator yemhepomudziyo wemakanika unoshandisa mweya wakamanikidzwa kugadzira kufamba kwemavharuvhu anoshanda. Zvinhu zvikuru zvinosanganisira:
- Mashandiro:Inoshandura kumanikidzwa kwemhepo (kazhinji 4–7 bar) kuita kufamba kwerotary kana linear.
- Zvikamu:Sirinda, pistoni, magiya, uye masipiringi.
- Mhando:
–Ma actuator epneumatic anoshanda kaviri:Zvinoda kumanikidzwa kwemhepo kuti uvhure uye uvhare
-Kudzoka kwechirimoma actuator epneumatic:Shandisa mhepo pane chimwe chinhu uye sipiringi pane chimwe (dhizaini isingakanganise kutadza).
Ma actuator epneumatic anokosheswa nekuda kwekumhanya kwawo, kuvimbika, uye kukodzera kwawo munzvimbo dzinoputika kana dzinopisa zvakanyanya.

A vharuvhu yebhorainodzora kuyerera kwemvura uchishandisa bhora rinotenderera rine gomba (buri) pakati paro. Kana yakabatana nepaipi, inobvumira kuyerera kwemvura; kana yatenderedzwa nemadhigirii makumi mapfumbamwe, inovhara kuyerera kwemvura. Hunhu hunokosha:
- Dhizaini:Sarudzo dzakasimba, dzakakwana kana dzakaderedzwa.
- Kuisa chisimbiso:Dzima zvakasimba nePTFE kana zvigaro zvesimbi.
- Kugara kwenguva refu:Yakanakira kushandiswa kwesimba repamusoro uye tembiricha yepamusoro.
Mhando dzePneumatic Actuator Ball Valves
Mavharuvhu ebhora repneumatic anorongwa nekugadzirwa uye basa:
1. Nemagadzirirwo eVharufu:
–Vharuvhu yebhora yakazara:Bore rinoenderana nedhayamita yepombi kuitira kuti mvura isatsvedzerere zvakanyanya.
–Vharuvhu yebhora ine chiteshi chakaderedzwa:Bore diki kuti mvura inyatsoyerera zvakanaka.
–V-port bhora vharuvhu:Bore rakaita seV kuti rikwanise kudhonzwa nemazvo.
2. Nekushanda:
–Inoshanda kaviri:Inoda mhepo yekuvhura nekuvhara.
–Kudzoka kwechirimo:Inodzokera otomatiki panzvimbo yakachengeteka kana mweya warasika.
Mabhenefiti ePneumatic Actuator Ball Valve
1. Kuvhara Kwakanaka Kwazvo:Kudzima kwakasimba semabhurumu, kunyangwe kana paine kumanikidzwa kwakanyanya.
2. Kushanda Nekukurumidza:Kutenderera kwemadhigirii makumi mapfumbamwe kunobvumira kuvhura/kuvhara nekukurumidza.
3. Kugadziriswa Kwakaderera:Dhizaini iri nyore ine zvikamu zvishoma zvinokurumidza kupera.
4. Kuchinja-chinja:Inoenderana nemidziyo yemagetsi ine hukasha (acids, gasi, steam).
5. Hupenyu Hurefu hweBasa:Haipindi ngura uye tembiricha yakakwira.
Vharuvhu yeBhora yePneumatic Actuator vs. Mamwe Mavharuvhu
| Rudzi rweVharuvhu | Misiyano Yakakosha |
| Vharuvhu yeButterfly yePneumatic | Yakareruka uye yakachipa asi isingashande zvakanyanya pakusunga jira rine simba rakawanda. |
| Vharuvhu yeGedhi rePneumatic | Kushanda zvishoma nezvishoma; zvakakodzera kuti mvura ifambe zvakanaka, kwete kupwanya mvura. |
| Vharuvhu yeGlobe yePneumatic | Zviri nani pakupinza simba nemazvo asi kudzvanya kwakanyanya uye chimiro chakaoma. |
| ESDV (Emergency Shutdown Valve) | Inokoshesa kuvharwa kwekuchengetedza nekukurumidza; kazhinji inosanganiswa nemavharuvhu egedhi/bhora. |
Mashandisirwo ePneumatic Actuator Ball Valves
1. Oiri neGasi:Kuvhara nekudzora mapaipi, nzvimbo dzekuchenesera, uye mafekitori eLNG.
2. Kugadziriswa kweMakemikoro:Bata mvura inoparadza uye zvinhu zvinosvibisa zvakanyanya.
3. Kurapa Mvura: Kutarisira mvura inonwiwa, mvura yakasviba, uye masisitimu ekudiridza.
4. Kugadzira Simba:Gadzirisa utsi hwemvura nekupisa mumaturbine.
5. Mishonga:Magadzirirwo ehutsanana ekubata mvura isina utachiona.
Mhedziso
Mavharuvhu ebhora emagetsi anogadzira mhepo anoshanda zvakanaka munzvimbo dzine kumanikidzwa kwakanyanya, tembiricha yakakwira, uye ngura, achipa chisimbiso chisina kuenzana uye kuvimbika. Kugona kwawo kuchinjika mumaindasitiri kunoita kuti ave musimboti wehurongwa hwemazuva ano hwekudzora kuyerera kwemvura.
