Ma valve ndi zida zomwe zimagwiritsidwa ntchito poyang'anira madzimadzi ndipo zimagwiritsidwa ntchito poyang'anira kutuluka kwa madzi. Malinga ndi kapangidwe kawo ndi ntchito, ma valve amatha kugawidwa m'mitundu yambiri. Otsatirawa ndi opanga ma valve a Tianjin kuti adziwitse kapangidwe ka valve ndi gulu:
Choyamba, mawonekedwe a valve:
1. Thupi la valve: gawo lalikulu la valve, lomwe limayang'anira kukonza ndi kuthandizira zigawo zina.
2. Valve disc (disc) : Gawo lomwe limayendetsa kutsegula ndi kutseka kwa valve kuti madzi aziyenda.
3. Mpando wa vavu: ndi chimbale kupanga chisindikizo, kulamulira madzimadzi ndi kuzimitsa.
4. Kusindikiza pamwamba: malo olumikizana pakati pa diski ya valve ndi mpando, kupyolera mu malo osindikizira kuti akwaniritse ntchito yosindikiza ya valve.
5. Ndodo shaft: yolumikizidwa ndi diski ya valve kusamutsa mphamvu yogwiritsira ntchito ndikuwongolera kutsegula ndi kutseka kwa valve.
6. Chipangizo chogwiritsira ntchito: chogwiritsidwa ntchito poyang'anira kusintha kwa valve, kungaphatikizepo chipangizo chogwiritsira ntchito pamanja, chipangizo chamagetsi, chipangizo cha pneumatic, etc.
Chachiwiri, gulu la mavavu:
1. Gulu molingana ndi mawonekedwe:
- Mavavu a Catalog: disc kapena disc imayenda mmwamba ndi pansi pamzere wowongoka, monga ma valve a globe, ma valve owunika, ndi zina.
- Pulagi valve: chimbale kapena chimbale chimazungulira mozungulira, monga ma valve a mpira, ma valve agulugufe, ndi zina.
- Valve yolimba kwambiri: Onjezani njira zopapatiza mu valavu kuti muwonjezere kukana kwamadzimadzi, monga ma throttle valves, ma valve a zipata, ndi zina zambiri.
2. Gulu pogwiritsa ntchito:
- Vavu yoyimitsa: imagwiritsidwa ntchito kuwongolera madzi kuti azitsegula ndi kuzimitsa, monga kuyimitsa kutuluka kwamadzimadzi kapena kuwongolera madzimadzi.
- Chongani valavu: imagwiritsidwa ntchito poletsa kutuluka kwamadzimadzi, kuteteza kutuluka kwa reverse.
- Vavu yowongolera: yomwe imagwiritsidwa ntchito kuwongolera kuthamanga, kuthamanga kapena kutentha kwamadzi.
- Vavu yachitetezo: imagwiritsidwa ntchito kutulutsa kupanikizika pamene kukakamizidwa kupitilira mtengo wokhazikitsidwa kuti apewe kuwonongeka kwa zida kapena mapaipi.
- Vavu yotulutsa mpweya: imagwiritsidwa ntchito pochotsa gasi papaipi kuti zitsimikizire kuti madziwo akuyenda bwino.
3. Malinga ndi kugwiritsa ntchito gulu la media:
- Vavu yamadzi: imagwiritsidwa ntchito kuwongolera kuyenda kwamadzi, monga valavu yoperekera madzi, valavu yamadzi, ndi zina.
- Vavu yamafuta: imagwiritsidwa ntchito kuwongolera kutuluka kwa gasi, monga valavu yowongolera mpweya, valavu ya mpira wa pneumatic, etc.
- Vavu yamafuta: imagwiritsidwa ntchito kuwongolera kuyenda kwamafuta, monga hydraulic control valve, valve seal valve, etc.
- Vavu ya nthunzi: imagwiritsidwa ntchito kuwongolera kuyenda kwa nthunzi, monga valavu yowongolera nthunzi, valavu yamphamvu ya nthunzi, ndi zina.
4. Gawani motengera kupsinjika:
- Valavu yotsika: yoyenera malo ogwirira ntchito otsika, nthawi zambiri osakwana 1.6MPa.
- Vavu yapakatikati: yoyenera malo ogwirira ntchito, nthawi zambiri pakati pa 1.6MPa ndi 10MPa.
- Vavu yothamanga kwambiri: yoyenera malo ogwirira ntchito, nthawi zambiri kuposa 10MPa.
Zomwe zili pamwambazi ndizopangidwe ndi kagawo ka valve. Posankha valavu yoyenera, m'pofunika kuganizira mozama zofunikira zaumisiri ndi mawonekedwe azama TV, ndikusankha wopanga ma valve apamwamba kwambiri kuti atsimikizire kudalirika ndi moyo wautumiki wa valve. Kuti mumve zambiri komanso chitsogozo, tikulimbikitsidwa kulumikizana ndi akatswiri opanga ma valve.
