Pali mitundu yambiri komanso mitundu yovuta yamavuvu, makamaka kuphatikiza ma valve a pachipata, mavesi adziko lapansi, mavavu a gulugufe, valavu yam'manja, ma valve atchvu, diaphragm, diaphragm valavu.
1 Gulugufe wa Gulugufe
Mbale ya Gulugufe ndiye ntchito yotseguka ndi yotseka ya gulugufe imatha kumalizidwa ndi kuzungulira 90 ° mozungulira maxis okhazikika m'thupi la valavu. Chipinda cha gulugufe chimakhala chochepa kwambiri kukula, kuwala kolemera komanso kosavuta, ndipo kumakhala kokha magawo ochepa. Ndipo zimangofunika kuzungulira 90 °; Itha kutsegulidwa ndikutseka mwachangu, ndipo opareshoni ndi yosavuta. Nyama ya gulugufe ikakhala yotseguka, makulidwe a gulugufe ndi omwe amangoganiza kuti wavala bwino kwambiri, motero kugwedezeka kwa valavu ndi yaying'ono, motero kumakhala kochepa kwambiri. Valani wa gulugufe wagawidwa m'masindikiza otanuka ndi chisindikizo chachitsulo cholimba cholimba. Valve wambiri, mphete yolumikizira ikhoza kukhala yolumikizidwa m'thupi la valavu kapena yolumikizidwa ndi chimbale cha disc, ndi magwiridwe antchito abwino, omwe angagwiritsidwe ntchito kutolatiza, sing'anga waluso. Mavavu okhala ndi zisindikizo zachitsulo nthawi zambiri amakhala ndi moyo wautali kuposa omwe ali ndi zisindikizo zotsekemera, koma ndizovuta kukwaniritsa. Nthawi zambiri amagwiritsidwa ntchito pakapita nthawi yayikulu yosintha ndikuponderezedwa ndikufuna kugwira ntchito bwino. Zisindikizo zachitsulo zimatha kusintha kutentha kwambiri, pomwe zisindikizo zowoneka bwino zimakhala ndi chilema chokhala ndi kutentha.
2Pachipata
Valavu ya pachipata ikutanthauza valavu yomwe kutseguka komwe kutseguka ndi kutseka kwa valavu) kumayendetsedwa ndi valve nthomba ndikuyenda kapena kudula mandimu. Poyerekeza ndi chipata cha Globe, valavu ya pachipata ili bwino kungokhalira kugwira ntchito, kukana kwamadzi pang'ono, kuyesetsa kutsegulana ndi kutseka, ndipo kuli ndi kusintha kwina. Ndi imodzi mwamphamvu yomwe imagwiritsidwa ntchito kwambiri. Choyipa ndichakuti kukula kwake ndi kovuta, kapangidwe kake kamakhala kovuta kwambiri kuposa valavu yadziko lapansi, malo otetemera ndi osavuta kuvala, ndipo sizophweka kukhalabe. Nthawi zambiri, sioyenera kugwedezeka. Malinga ndi mawonekedwe a ulusi pachipata cha chipata, imagawidwa m'mitundu iwiri: mtundu wa ndodo ndi mtundu wakuda. Malinga ndi mawonekedwe a chipata, itha kugawidwa m'mitundu iwiri: mtundu wa mtundu wofanana.
3 Chongani valavu
Valani valavu ndi valavu yomwe imatha kuletsa kudzipatula kwa madzimadzi. Valap ya valavu ya cheke imatsegulidwa pansi pa kupanikizika kwa madzimadzi, ndipo madzi amatuluka kuchokera ku mbali imodzi kupita kumbali yotuluka. Kupanikizika kwa timet kuli kotsika kwambiri kuposa mbali yotuluka, valavu imatseka yosiyana siyana, mphamvu yake yokoka ndi zinthu zina popewa madzi oyambira. Malinga ndi kapangidwe kake, imatha kugawidwa mu valavu ya valavu ya valavu ya Swing. Mtundu wokweza uli ndi magwiridwe antchito abwino ndi kukana kwamadzi kwambiri kuposa mtundu wozungulira. Pakuti doko loyanjidwa la chitoliro cha pampu, valavu yotsika iyenera kusankhidwa. Ntchito yake ndikudzaza chitoliro cha pampu ndi madzi musanayambe pampu; Sungani chitoliro chosungiracho chitolirochi ndi thupi la pampu lodzala ndi madzi pambuyo pa pampu ikayimitsidwa, kuti mukonzekere kuyambiranso. Valavu pansi nthawi zambiri imangoyikidwa pa mapaipi okhazikika a pampu, ndipo sing'anga imayenda kuchokera pansi mpaka pamwamba.
4 Globeb Valve
Valve Plave ndi valavu yotsekedwa yotsekedwa, ndipo membala wotseguka ndi wotseka (Valve) amayendetsedwa ndi steve stem kuti asunthire ndikutsikira kumpando wa valavu ya valavu (pamwamba). Poyerekeza ndi chipata cholimba, chikusintha bwino magwiridwe antchito, kusachita bwino kosauka, kapangidwe kake, kokhazikika komanso kukonza madzi ambiri.
5 mpira valavu
Mbali yotseguka ndi yotseka ya valavu ya mpira ndi gawo limodzi ndi dzenje, ndipo magawo amazungulira ndi valve kuti azindikire kutseguka ndi kutseka kwa valavu. Valove valavu imakhala ndi kapangidwe kambiri, kusinthira mwachangu, kuwongolera kosavuta, kukula kochepa, kulemera kopepuka, kukana kwamadzimadzi, kukonza bwino.
6 valve
Kapangidwe ka vuri ya Throttt ndi chimodzimodzi ndi za Valve Glober kupatula dilve. Disve disc ndi chinthu chosokera, ndipo mawonekedwe osiyanasiyana ali ndi mawonekedwe osiyanasiyana. Dongosolo la mpando wa Valavu siliyenera kukhala lalikulu kwambiri, chifukwa kutalika koyambirira ndikochepa. Kukula kwa sing'anga kumawonjezeka, kotero imathandizira kukokoloka kwa disc. Valavu ya Throttt ili ndi miyeso yocheperako, yolemera komanso kusintha kwabwino, koma kulondola kwa kusintha sikuli kumwamba.
7 Pulogalamuyi
Valive Valve imagwiritsa ntchito thupi la pulagi yokhala ndi dzenje ngati chitseko chotseguka komanso chotseka, ndipo thupi la plugi limazungulira ndi chidutswa cha valavu kuti izindikire kutsegulidwa ndi kutseka kwa valavu. Valve Valve ili ndi maubwino osakanikirana, kusinthasintha mwachangu, kugwira ntchito kosavuta, kukana kwamadzi ochepa, kulemera kochepa komanso kulemera kochepa. Pali mbali zowongoka, njira zitatu ndi zinayi zotsatila mitengo. Valavu yolunjika yolumikizidwa imagwiritsidwa ntchito kudula pakati, ndipo mavuwa atatu ndi anayi amagwiritsidwa ntchito kusintha njira ya sing'anga kapena kugawa sing'anga.
8 diaphragm valavu
Chigawo chotseguka komanso chotseka cha valavu ya diaphragm ndi diaphragm ya mphira, yomwe imasungidwa pakati pa thupi la valavu ndi chivundikiro cha valavu. Gawo la pakati pa diaphragm limakhazikika pa steve, ndipo thupi la valavu limakhala ndi mphira. Popeza sing'anga salowa mkati mwa chivundikiro cha valavu, tsinde la valavu sifunikira bokosi lokhazikika. Valavu ya diaphragm ili ndi mawonekedwe osavuta, magwiridwe antchito abwino, kukonza kosavuta komanso kukana kwamadzi. Mavavu a Diaphragm amagawidwa kukhala mtundu wa Weir, molunjika kudzera mu mtundu, mtundu wa ngodya kumanja ndi mtundu woyenda molunjika.
