Mavharuvhu midziyo yakajairika mumunda wekudzora mvura uye inoshandiswa kudzora kuyerera kwemvura. Maererano nemaitiro avo uye basa, mavharuvhu anogona kukamurwa kuva marudzi mazhinji. Izvi zvinotevera mugadziri weTianjin valve kuunza chimiro uye kupatsanurwa kwevhavha:
Kutanga, iyo valve chimiro:
1. Muviri wevhavha: chikamu chikuru chevhavha, chinotarisirwa kugadzirisa uye kutsigira zvimwe zvikamu.
2. Valve disc (disc) : Chikamu chinodzora kuvhura nekuvhara kwevhavha yekuyerera kwemvura.
3. Chigaro chevhavha: ne disc kuti iite chisimbiso, kudzora mvura uye kuvhara.
4. Chisimbiso chepamusoro: nzvimbo yekubatanidza pakati pevhavha disc uye chigaro, kuburikidza nechisimbiso chepamusoro kuti uwane kushanda kwekuvhara kwevhavha.
5. Rod shaft: yakabatana nevhavha disc kuendesa simba rekushanda uye kutonga kuzarura nekuvhara kwevhavha.
6. Chishandiso chekushanda: chinoshandiswa kudzora chigadziko chevhavha, chinogona kusanganisira chigadziro chekushandisa, magetsi, pneumatic device, nezvimwewo.
Chechipiri, kupatsanurwa kwemavharuvhu:
1. Kurongwa maererano nechimiro chechimiro:
- Catalog mavharuvhu: dhisiki kana dhisiki inofamba ichikwira nekudzika axis mumutsara wakatwasuka, senge globe mavharuvhu, cheki mavharuvhu, nezvimwe.
- Plug valve: iyo disc kana disc inotenderera yakatenderedza axis, senge bhora mavharuvhu, butterfly mavharuvhu, nezvimwe.
- High resistance valve: Wedzera mitsetse yakamanikana muvharuvhu kuti uwedzere kuramba kwekuyerera kwemvura, senge throttle mavharuvhu, gedhi mavharuvhu, nezvimwe.
2. Kuronga nekushandisa:
- Misa vharafu: inoshandiswa kudzora mvura nekudzima, sekumisa kuyerera kwemvura kana kudzora mvura.
- Chengetedza valve: inoshandiswa kudzivirira kudzoka kwemvura, kudzivirira kuyerera kweiyo reverse.
- Regulating valve: inoshandiswa kugadzirisa chiyero chekuyerera, kudzvanywa kana tembiricha yemvura.
- Chengetedzo vharafu: inoshandiswa kuburitsa kudzvanywa kana kudzvanywa kwadarika kukosha kweseti kudzivirira kukuvadzwa kwemidziyo kana mapaipi.
- Exhaust valve: inoshandiswa kubvisa gasi kubva papombi kuti ive nechokwadi chekushanda kwemvura.
3. Zvinoenderana nekushandiswa kweiyo media classification:
-Ivhavha yemvura: inoshandiswa kudzora kuyerera kwemvura, senge vharafu yemvura, vharafu yemvura, nezvimwe.
- Gasi vharafu: inoshandiswa kudzora kuyerera kwegasi, senge gasi regulating valve, pneumatic bhora vharafu, nezvimwe.
- Oiri vharafu: inoshandiswa kudzora kuyerera kwemafuta, senge hydraulic control valve, mafuta seal valve, nezvimwe.
-Steam valve: inoshandiswa kudzora kuyerera kwechitsinga, senge vharafu inodzora vharafu, vharafu simba, nezvimwe.
4. Rongedza nedanho rekushushikana:
- Low pressure valve: yakakodzera kune yakaderera kumanikidza kushanda nharaunda, kazhinji isingasviki 1.6MPa.
- Medium pressure valve: inokodzera yepakati kumanikidza kushanda nharaunda, kazhinji pakati pe1.6MPa ne10MPa.
- High pressure valve: yakakodzera kune yakanyanya kumanikidza kushanda nharaunda, kazhinji yakakura kupfuura 10MPa.
Izvo zviri pamusoro ndiyo maitiro uye kupatsanurwa kwevhavha. Paunenge uchisarudza vharafu yakakodzera, zvinodikanwa kunyatso funga nezve izvo zvinodikanwa zveinjiniya uye hunhu hwemidhiya, uye sarudza yemhando yepamusoro yekugadzira valve kuti ive nechokwadi chekuvimbika uye hupenyu hwebasa revhavha. Kuti uwane rumwe ruzivo rwakadzama uye kutungamira, zvinokurudzirwa kubata nyanzvi vanogadzira mavharuvhu.
