Valve ndi gawo lowongolera mumayendedwe amadzimadzi otumizira, omwe ali ndi ntchito monga kutsika, kusintha, kusokoneza, kuletsa kutengera pakali pano, kuwongolera ma voliyumu, kupatutsidwa kapena kuthamanga kwa kusefukira.
Pali mitundu yambiri ya ma valve, ndipo ikhoza kugawidwa m'magulu awiri:
1. Kalasi ya valve yodutsa: Imagwiritsidwa ntchito makamaka podula kapena kulumikiza kuyenda kwapakati.Kuphatikiza valavu yachipata, valavu yakuya, valavu ya diaphragm, valavu ya rotor, valve ya mpira, valavu ya butterfly, ndi zina zotero.
2. Gulu la valavu yamagulu: Amagwiritsidwa ntchito makamaka poyendetsa kayendedwe, kuthamanga, ndi zina zapakati.Kuphatikizira ma valve owongolera, ma throttling valves, ma valve ochepetsa kuthamanga, etc.
3. Kalasi ya valve yoyimitsa kumbuyo: Imagwiritsidwa ntchito kuteteza sing'anga kuti isasinthe.Kuphatikiza valavu yoyimitsa yamagulu osiyanasiyana.
4. Kalasi ya valve ya dives: imagwiritsidwa ntchito kugawa, kupatukana kapena kusakanikirana.Kuphatikiza ma valve ogawa ndi ma hydrophobic mavavu amitundu yosiyanasiyana.
5. Gulu la ma valve otetezedwa: amagwiritsidwa ntchito pachitetezo chachitetezo chopitilira muyeso.Kuphatikizapo mitundu yosiyanasiyana ya ma valve otetezera.
Zida zamavavu:
1. Mavavu azinthu zopanda zitsulo monga mavavu a ceramic, mavavu owonjezera magalasi, mavavu apulasitiki, monga PVC ndi mavavu a ASB.
2. Mavavu achitsulo monga valavu yamkuwa, valavu ya aluminiyamu, valavu yotsogolera, titaniyamu valavu yachitsulo, valavu ya carbon steel, valve low alloy steel valve, high alloy steel valve, valve iron valve.Mipikisano -cast zitsulo ndi mavavu pamwamba ntchito m'madera ndi mkulu chisanu kukana.
3. Mavavu azitsulo azitsulo monga valavu yotsogolera, valavu ya pulasitiki, valavu ya enamel, ndi tetramel fluorine valve.Nthawi zambiri amagwiritsidwa ntchito mu engineering ya corrosive sewage.
Geti
Valve yachipata imagwiritsidwa ntchito ngati nthawi yomaliza, ndipo kuyendayenda konse kumalumikizidwa mwachindunji pamene kutsegulidwa kwathunthu.Valve yachipata nthawi zambiri imakhala yoyenera pazikhalidwe zogwirira ntchito zomwe sizifunikira kutsegula ndi kutseka, ndikusunga chipata chotseguka kapena chotsekedwa kwathunthu.Osagwiritsidwa ntchito ngati zowongolera kapena zoponya.Kwa mauthenga othamanga kwambiri, chipata chingayambitse kugwedezeka kwa chipata pansi pa malo otsegulira, ndipo kugwedezeka kungawononge chisindikizo cha chipata ndi mpando wa valve, ndipo kuponyera kudzachititsa kuti chipata chiwonongeke ndi sing'anga.Valve yachipata imatha kukhala yoyenera kutentha kwapansi kapena kutentha kwambiri komanso kuthamanga kwambiri, koma nthawi zambiri sagwiritsidwa ntchito kunyamula mapaipi monga matope ndi media zina.
Ubwino:① Kukana kwamadzimadzi ndikochepa;② torque yofunikira pakutsegula ndi kutseka ndi yaying'ono;③ angagwiritsidwe ntchito pa mphete mauna payipi ikuyenda mbali ziwiri, ndiye kuti, otaya sing'anga si malire;Kuwonongeka kwa sing'anga ndi kakang'ono kuposa valavu yowonongeka;⑤ Mapangidwe a thupi ndi ophweka, ndipo kupanga ndi bwino;⑥ Kutalika kwa kapangidwe kake ndi kochepa.
Zoyipa:① Kukula ndi kutalika kwa kutsegula ndi kwakukulu, ndipo malo omwe akuyenera kuikidwa nawonso ndi aakulu;② Panthawi yotsegula ndi kutseka, munthu wosindikizayo amakhala ndi mikangano, kuwonongeka kwakukulu, ndipo n'kosavuta kuyambitsa abrasion pa kutentha kwakukulu;③ Vavu yachipata chachikulu imakhala ndi zisindikizo ziwiri, zomwe zimawonjezera zovuta pakukonza, kugaya ndi kukonza;
Valve yotseka
Valve ya truncant imagwiritsidwa ntchito kuti muchepetse kutuluka kwapakati.
