Kusiyana kwakukulu pakati pa valavu kuchokera ku valavu, kusanthula kwa kapangidwe kake ka mapangidwe kumakupatsani mwayi kuti mupange kusankha kwa chipangizo chothandizira pokhazikitsa mapaipi.
Chiwembu cha valavu ya wedge.
Maval
Valavu ndi chipangizo chotsimikizika chomwe chimakhala ndi chimbale cha disc, pepala kapena kulowetsana ndikuyenda pamtunda wosindikizira axis.Kutengera ndi kapangidwe ka Valavu, pakhoza kukhala ndime ndipo kunang'ambika kwa mabowo osindikizira ochepera kuposa mapaipi a pa mapaipi.
Kutengera ndi shumetry geometry, mavavuwo amalekanitsidwa kukhala ofanana ndi wedge. Zigwa Zili ndi zotsekemera zotsekemera zomwe zili pamalo ena. Nthaka yatsetseyo imatha kukhala yolimba yolimba, yolimba kapena contractive.
Makunja ofananira ali ndi zotsekera ndi zotchingira zomwe malo osindikizira omwe amagwirizana amafanana. Kapangidwe kameneka kamatha kukhala chidutswa chimodzi (bwenzi) kapena ziwiri.
Mavavuwo amatha kukhala ndi spindle (stock) komanso chosasinthika (kuzungulira). Amasiyana mu kapangidwe kake kake, komwe kumasunthira shutter. Mavavu okhala ndi spindle yozungulira imakhala ndi kukula kocheperako.
Ubwino ndi Zovuta za Maval
Valve Code: 1 - Thupi la Valavu, 3 - nati, 3 - Washer, wazaka 4, wazaka 6, 15 - 15 - 15 - Elnik Bush, 11 - Flyweel, 12 - Shirher, 13 - Screw, 14 - Caid Washer.
Ubwino waukulu wa mavavuwo ndikuti palibe chizolowezi chothana ndi zovuta za sing'anga panthawi yosunthira thupi, zomwe zimayesetsa kusuntha chotseka. Kusasinthika kwa kutuluka kwa sing'anga yonyamula ndi zolimba zazing'ono zomwe zili pamalo otseguka ndikofunikira kwambiri.
Chifukwa cha kapangidwe kake kake, kugwiritsa ntchito mavuvu kumatha kugwiritsidwa ntchito m'njira zosiyanasiyana zoyendetsedwa ndi sing'anga owonjezera, pomwe pamanja olumikizirana, pakufunika kusintha njira yoyenda mkati mwa malo amkati.
Choyipa chachikulu cha kapangidwe kake ndichakuti pakusunthira mavavu a mavesi, mikangano yamphamvu imachitika. Mavesiwo ali ndi kutalika kwakukulu chifukwa chakufunika kowonjezera ndodo.

Kutsekeka kwakhala pakatikati, gawo lagombe la nyanjayo limathamanga kwambiri, limayenda mwachangu kumadera otsika kumapeto kwa mphete, ndikuwapangitsa kuti azitha kuvala mokhazikika ndi sing'anga yolimba. Chifukwa chake, mutatha kugwirira ntchito pang'ono pang'ono, valavu siyikuperekedwa ndi kulimba kokwanira pomwe atsekedwa. Choyipachi ndichabe chosiyanasiyana pamitundu yosiyanasiyana ndikuchepetsa kugwiritsa ntchito valavu ngati chinthu chosintha. Kuphatikiza apo, mapangidwe ake a mavavuwo ndi osakhutiritsa.
Kugwiritsa Ntchito ndi Kugwiritsa Ntchito Mavalve
Mavavuwo amagwiritsidwa ntchito pamapaipili ndi mainchesi oposa 50 mm, pomwe osalala a mtanda ndikofunikira kuti ateteze matenda a hydrauloc.Amagwiritsidwa ntchito mu mpweya wowongolera mpweya ndi mpweya wabwino (komanso mu ntchentche), chinsalu cha ma valve ndi chiwembu choyambirira, chomwe chimakhala chizithunzithunzi cha zitsulo, zomwe zimasunthira mu axis ku thendricular mpaka axis wa mpweya.
Osamachita popanda maamwazi komanso mu chipangizo cha makina opukutira ndi kusoka, mapaipi a mafuta, komanso makina ena opanga mafakitale. Ambiri molakwika amakhulupirira kuti mavamuwo ndi mitundu yosiyanasiyana, koma izi ndi zida zosiyanasiyana zomwe zimakhala ndi kusiyana kwakukulu komwe kumatsimikizira mawonekedwe ochita opaleshoni.
Chipangizo ndi Mavavu
Deke la Chipata cha Sealerterry: 1-Sydber, Phulusa 2-Plate, Milandu ya Mipando 3, 5-mphete, ndodo 7, Ndodo 9, zosindikiza za 8, 11- Chophimba, mafuta 12-Funi.
Valavu ndi valavu, yotsekera yomwe imasuntha ndi awiri opindika. Mapangidwe amapangidwa mu ulusi (wophatikizira) komanso wolumikiza ndi mapaipi a maipi.
Kutengera ndi makonzedwe atulutsidwe ndi kuwongolera maamba, mavuvu angu ndi kudutsa. Magawo a mavesi amaphatikizapo zomangira zomwe nzomwe zimatulutsa ndi zipamba zolumikizira ndizofanana kapena zikugwirizana. Valande lamphamvu, limakhala ndi zida zanthawi zonse.
Kutengera ndi cholinga, chitetezo, chokhazikitsidwa, kudula, kudutsa, kupuma, kusinthanso.
Valatiyo ikhoza kukhala yabwino komanso masabata awiri. Maulamuliro Sabata Osakwatira, nawonso, mu mawonekedwe a shutter agawidwa mu singano ndi mbale. Valavu yokhala ndi chiwongolero cha buku lomwe shupyo imayenda ndi awiri opindika, nthawi zambiri imatchedwa valavu. Kusiyanitsa kuwongolera ndikuyima mavavu. Cholinga cha mavavu otsekeka ndi odzaza kwathunthu pa kutuluka kwa sing'anga, chifukwa cha izi ali ndi thupi lokhazikika.

Mavavu a membrane - mapangidwe a zida zam'madzi omwe amadutsamo kutuluka kwa sing'anga kumachitika pogwiritsa ntchito matenda osokoneza bongo (pulasitiki, rabara). Makina awa amapangidwa ndi chitsulo ndi zokutira zamkati ndi zida zosagonjetseka (mphira, pulasitiki, enamel).
Valavuyo ndiye kapangidwe ka zolimbikitsidwa, momwe kuchuluka kwa madzi akutuluka kumapangidwira chifukwa chokopa mutsetse vale ya valavu yomwe ili mkati mwa valavu yomwe ili mkati mwa valavu yomwe ili mkati mwa valavu yomwe ili mkati mwa valavu. Ma Valves amagwiritsidwa ntchito onse awiriwa ndi payipi.
Ma Scheme Shael ndi Spindle yovomerezeka.
Valve valavu imapangidwa kuti itulutsidwe ndi mpweya kapena mpweya ndipo zimalepheretsa kusintha kwa akasinja mu njira "yaying'ono" ndikupumira. Lingaliro la "lalikulu" likuchitika pamtengo ndi kuyenda kwamadzi, "yaying'ono" imayambitsidwa ndi kutentha.
Chifukwa cha mavavuwo, ndizotheka kupewa kupangika kwa mtsinje wa sing'anga. M'mavalo oyang'ana, thupi lotseka limatseguka ndi mtsinje wa sing'anga ndipo imatsekedwa. Mapangidwe osinthika a valavu ali ndi chotsekera chomwe chimapangitsa kuti kuyenda kobwezeretsa. Mapangidwe, okhala ndi mauna, amaikidwa kumayambiriro kwa bomba la kachilomboka. Votve Provitary Valani yokhala ndi chotseka chozungulira mozungulira, chomwe chimapezeka pamwamba pa mpando wa Valve.
Zabwino ndi zolakwika za valavu
Ubwino waukulu wa valavu ndi kusakhala ndi mikangano yopikisana nawo, pomwe yatsekedwa, popeza chotsekeracho chimasunthira mwapadera, zomwe zimachepetsa chiopsezo chowonongeka. Valavuyo ili ndi kutalika kocheperako poyerekeza ndi Valve chifukwa chakuti matenda a spindle ndi ochepa ndipo sakuposa ma piperi apakati. Komabe, ali ndi kutalika kwakukulu, popeza ndikofunikira kuperekera kuyenda mkati mwa mlanduwo.
Pa valavu, wotsekemera amasuntha perpendicelarly, pa nthawi yotseka dongosolo, malo osindikizira a kukangana sayesedwa, ndipo izi zimalepheretsa kufooka.
Kusowa kwa mavumbi ndi kukana kwakukulu kwa hydraulic. Zimachitika chifukwa cha kusintha komwe kumayenda kwa sing'anga. Kusintha kumeneku kumachitika kawiri mkati mwa nyumba.
Valavuyo imadziwika kuti ili ndi malire pakuchita opareshoni ndipo imangogwiritsidwa ntchito mogwirizana ndi kayendedwe ka antchito. Mapangidwe amakonzedweratu kuti kutuluka kumatha kutayikira pansi pa mbale ndikuyika kukakamizidwa kuchokera ku chishalo chotsekedwa. Kutsegula valavu kumadzetsa miyala pazachisoni. Ngati valavu imayang'ana mbali inayo, pomwepo pamalo otsekedwa, mbaleyo idzalumikizidwa pachishalo, chomwe chingapangitse zovuta zazikulu pakutseguka. Zotsatira zake, kuwonongeka kwa mbale kuchokera mu ndodo ndi kutulutsa kwa valavu yatuluka.

Kusiyana kopatsa komanso kothandiza kumachita bwino ndi valavu
Kodi pali kusiyana kotani pakati pa valavu kuchokera ku valavu? Kusiyanako kumachitika chifukwa cha kapangidwe ka matupi awo otseka. M'mavesi, mpweya woyenda ndi madziwo ndi valavu, yomwe imakanikizidwa ndi nyengo yopingasa ya mtsinje wazungulira, chifukwa cha izi, kugwada kwamitundu iwiri kapena madzi kumapangidwa, koma kukana kumawonjezeka.
Mosiyana ndi valavu yama Valve, valavu imakhala ndi chotupa chosalala kapena cha centoid, zimapangitsa kuti kusunthika kumaso.
M'mavalo, zotsekemera zotuluka chifukwa cha kunyowa kapena chikho, chotsika mpaka njira yoyenda.
Ndi mapangidwe oyenera a valavu, palibe chopatsira mabowo ochititsa chidwi, poyerekeza ndi zothandizira ndi zotulutsa. Pankhani yogwiritsa ntchito mavavu, zosankha zingapo ndizotheka. M'mapaipi ambiri, mahatchi onse oyendetsa magudumu amaikidwa, momwe mulifupi wa dzenje la nyumbayo, nthawi zambiri limakhala ndi cholinga chochepetsa chimbudzi cha torque ndipo Zimapangitsa kuti zitheke kuchepetsa kuvala kwa malo osindikizira.
