Pali mitundu yambiri ndi mitundu yovutamavavu, makamaka mavavu pachipata, mavavu globe, mavuvu throttle, valavu gulugufe, mavavu pulagi, mavavu mpira, mavavu magetsi, diaphragm mavavu, mavavu cheke, mavavu chitetezo, mavavu kuchepetsa kuthamanga, misampha nthunzi ndi mavavu mwadzidzidzi kuzimitsa-off, etc. , amene amagwiritsidwa ntchito valavu pachipata, valavu globe, throttle valavu, valavu pulagi, gulugufe valavu, valavu mpira, valavu cheke, diaphragm valavu.
1 Valve ya butterfly
Vavu ya butterfly ndi kutsegula ndi kutseka kwa mbale ya butterfly yomwe imatha kumalizidwa pozungulira 90 ° mozungulira mozungulira mu thupi la valavu. Vavu ya butterfly ndi yaying'ono mu kukula, kulemera kwake ndi kosavuta, ndipo imakhala ndi magawo ochepa okha. Ndipo zimangofunika kuzungulira 90 °; ikhoza kutsegulidwa ndi kutsekedwa mwamsanga, ndipo ntchitoyo ndi yosavuta. Pamene valavu agulugufe ali pa malo otseguka mokwanira, makulidwe a gulugufe mbale ndi kukana kokha pamene sing'anga umayenda mu valavu thupi, kotero kuthamanga dontho kwaiye valavu ndi laling'ono kwambiri, choncho ali bwino otaya makhalidwe. Vavu yagulugufe imagawidwa kukhala zotanuka zofewa chisindikizo ndi chitsulo cholimba chisindikizo. Valavu yosindikizira yokhazikika, mphete yosindikizira imatha kuikidwa pathupi la valve kapena kumangirizidwa pamphepete mwa diski, ndikuchita bwino kusindikiza, komwe kungagwiritsidwe ntchito popukutira, mapaipi apakati a vacuum ndi media zowononga. Mavavu okhala ndi zisindikizo zachitsulo nthawi zambiri amakhala ndi moyo wautali kuposa omwe amakhala ndi zotanuka, koma ndizovuta kuti asindikize kwathunthu. Amagwiritsidwa ntchito nthawi zambiri ndikusintha kwakukulu kwakuyenda komanso kutsika kwamphamvu komanso kumafuna kuwongolera bwino. Zisindikizo zazitsulo zimatha kusintha kutentha kwapamwamba, pamene zotanuka zimakhala ndi chilema chochepa chifukwa cha kutentha.
2Chipata cha valve
Vavu yachipata imatanthawuza valavu yomwe thupi lake lotsegula ndi lotseka (mbale ya valve) imayendetsedwa ndi tsinde la valve ndikuyenda mmwamba ndi pansi pambali yosindikizira ya mpando wa valve, yomwe imatha kulumikiza kapena kudula njira yamadzimadzi. Poyerekeza ndi valavu yapadziko lonse lapansi, valavu yachipata imakhala ndi ntchito yabwino yosindikiza, kuchepa kwamadzimadzi, kuyesetsa pang'ono kutsegula ndi kutseka, ndipo imakhala ndi kusintha kwina. Ndi imodzi mwama block valves omwe amagwiritsidwa ntchito kwambiri. Choyipa ndichakuti kukula kwake ndi kwakukulu, kapangidwe kake ndi kovutirapo kuposa valavu yapadziko lonse lapansi, malo osindikizira ndi osavuta kuvala, ndipo sikophweka kusamalira. Nthawi zambiri, sizoyenera kugwedeza. Malingana ndi malo a ulusi pa tsinde la valve valve, amagawidwa m'mitundu iwiri: mtundu wa ndodo yotseguka ndi mtundu wa ndodo yakuda. Malingana ndi mawonekedwe a chipata, chikhoza kugawidwa m'magulu awiri: mtundu wa wedge ndi mtundu wofanana.
3 Onani valavu
Valve yowunika ndi valavu yomwe imatha kulepheretsa kutuluka kwamadzimadzi. Chovala cha valve cha valve chotsegula chimatsegulidwa pansi pa mphamvu yamadzimadzi, ndipo madzi amadzimadzi amayenda kuchokera kumbali yolowera kupita ku mbali yotulukira. Pamene kupanikizika kumbali yolowera kumakhala kotsika kusiyana ndi komwe kumatuluka, valavu ya valve idzatsekeka pokhapokha ngati pali kusiyana kwa madzimadzi, mphamvu yake yokoka ndi zina zomwe zimalepheretsa madziwo kubwerera kumbuyo. Malinga ndi kapangidwe kake, imatha kugawidwa kukhala valavu yokweza ndi swing cheke. Mtundu wokweza umakhala ndi ntchito yabwino yosindikiza komanso kukana kwamadzimadzi kwakukulu kuposa mtundu wa swing. Kwa doko loyamwa la chitoliro choyamwa cha mpope, valavu yapansi iyenera kusankhidwa. Ntchito yake ndikudzaza chitoliro cholowera cha mpope ndi madzi musanayambe kupopera; sungani chitoliro cholowera ndi thupi la mpope lodzaza ndi madzi pompayo itayimitsidwa, kuti mukonzekere kuyambiranso. Vavu yapansi nthawi zambiri imayikidwa papaipi yoyima ya polowera, ndipo sing'angayo imayenda kuchokera pansi kupita pamwamba.
4 Valve yapadziko lonse lapansi
Vavu yapadziko lonse lapansi ndi valavu yotsekera pansi, ndipo membala wotsegulira ndi wotseka (valavu) amayendetsedwa ndi tsinde la valavu kuti asunthire mmwamba ndi pansi pamphepete mwa mpando wa valve (kusindikiza pamwamba). Poyerekeza ndi valavu yachipata, imakhala ndi kusintha kwabwino, kusagwira bwino ntchito yosindikiza, mawonekedwe osavuta, kupanga ndi kukonza bwino, kukana kwakukulu kwamadzimadzi ndi mtengo wotsika.
5 valavu ya mpira
Gawo lotsegula ndi lotseka la valve ya mpira ndi gawo lomwe lili ndi zozungulira kudutsa dzenje, ndipo gawolo limazungulira ndi tsinde la valve kuti lizindikire kutsegula ndi kutseka kwa valve. Valve ya mpira imakhala ndi dongosolo losavuta, kusinthasintha mofulumira, ntchito yabwino, kukula kochepa, kulemera kochepa, magawo ochepa, kukana kwamadzimadzi pang'ono, kusindikiza bwino komanso kukonza bwino.
6 Valve yamphamvu
Mapangidwe a valve throttle kwenikweni ndi ofanana ndi valavu yapadziko lonse kupatulapo diski ya valve. Valve disc ndi gawo lowongolera, ndipo mawonekedwe osiyanasiyana amakhala ndi mawonekedwe osiyanasiyana. Kutalika kwa mpando wa valve sikuyenera kukhala kwakukulu, chifukwa kutalika kotsegulira ndi kochepa. Kuthamanga kwapakati kumawonjezeka, kotero Kumafulumizitsa kukokoloka kwa disc valve. Valve ya throttle ili ndi miyeso yaying'ono, kulemera kopepuka komanso magwiridwe antchito abwino, koma kulondola kwakusintha sikwapamwamba.
7 Pulagi valve
Vavu ya pulagi imagwiritsa ntchito thupi la pulagi yokhala ndi dzenje ngati gawo lotsegula ndi lotseka, ndipo thupi la pulagi limazungulira ndi tsinde la valavu kuti lizindikire kutsegula ndi kutseka kwa valve. Valve ya pulagi ili ndi ubwino wa dongosolo losavuta, kusintha mofulumira, ntchito yabwino, kukana kwamadzimadzi pang'ono, magawo ochepa ndi kulemera kochepa. Pali ma valve owongoka, njira zitatu ndi zinayi. Chovala chowongolera chowongoka chimagwiritsidwa ntchito podula sing'anga, ndipo ma valve a njira zitatu ndi zinayi amagwiritsidwa ntchito kusintha njira yapakati kapena kugawa pakati.
8 Valavu ya diaphragm
Mbali yotsegula ndi yotseka ya valve ya diaphragm ndi diaphragm ya rabara, yomwe imayikidwa pakati pa thupi la valve ndi chivundikiro cha valve. Mbali yapakati yotuluka ya diaphragm imakhazikika pa tsinde la valavu, ndipo thupi la valve limakutidwa ndi mphira. Popeza sing'anga sichilowa mkati mwa chivundikiro cha valve, tsinde la valve silikusowa bokosi lodzaza. Valavu ya diaphragm ili ndi mawonekedwe osavuta, ntchito yabwino yosindikiza, kukonza kosavuta komanso kukana kwamadzi pang'ono. Mavavu a diaphragm amagawidwa kukhala mtundu wa weir, mtundu wowongoka, wolunjika kumanja ndi mtundu woyenda molunjika.
