A siteslockValavu ndi [1] Valavu yolunjika yomwe imatsegulira mwachangu, ndipo imagwiritsidwa ntchito pogwiritsa ntchito manyuzipepala oyimitsidwa chifukwa cha zomwe zimapangitsa kuti zisasunthike. Chofunika china ndichakuti ndizosavuta kuzolowera madera angapo, kuti valavu imodzi ithe kukhala awiri, atatu, kapena ngakhale anayi osiyana oyenda. Izi zimathandiza kuti mapangidwe a masipu apanduke, amachepetsa kuchuluka kwa mavavu omwe amagwiritsidwa ntchito, ndikuchepetsa kulumikizana komwe kumafunikira pazida.
Momwe zimagwirira ntchitositeslockmatupi okhala ndi mabowo ngati mabowo ngati mbali zotseguka komanso zotsekera. Tsamba la plug limazungulira ndi [2] tsinde kuti mukwaniritse kutsegula ndi kutseka. Chingwe chaching'ono, chosawerengeka, chimadziwikanso kuti "wowerengera". Thupi la Pulogalamu ya Pulogalamuyi ndi chinsalu chachikulu (palinso mthupi la cylindrical), yomwe imafanana ndi mawonekedwe a oritical a valavu ya valavu kuti apange awiri osindikizira. Valve Valve ndi mtundu wa valavu yomwe imagwiritsidwa ntchito, yokhala ndi kapangidwe kambiri, kutsegulira mwachangu komanso kutseka, komanso kukana kwamadzi. Ma Valve wamba aliwonse amadalira kulumikizana mwachindunji pakati pa thupi lazitsulo ndi thupi la valavu kuti isindikize, ndipo nthawi zambiri imangogwiritsidwa ntchito poyerekeza (zosakwana 100 mm).
Csonyeza
Malinga ndi mawonekedwe a mawonekedwe, imatha kugawidwa m'magulu anayi: valani valavu yolimba, valavu yolimbana ndi mapulani a valavu yam'madzi ndi valavu yopaka mafuta. Malinga ndi mawonekedwe a njirayi, imatha kugawidwa m'mitundu itatu: Kudutsa molunjika Valve valack valack valare yamphamvu ndi valavu inayi. Palinso mitengo ya chubu.
Zigwa Zosankhidwa Mwa Kugwiritsa Ntchito: Ma Valve Stop Agets, Mafuta Opaka Mafuta Opaka Mafuta, Masamba Atatu ndi Atatu ndi Awiri-Pulaginayi.
Ubwino
1. Valavu ya plugi imagwiritsidwa ntchito pochita masewera olimbitsa thupi pafupipafupi, ndipo kutseka ndi kutseka ndikosavuta.
2. Kukana kwamadzi kwa plugi ndi kochepa.
3. Valump Valve ili ndi kapangidwe kambiri, kukula kochepa, kulemera komanso kukonza kosavuta.
4. Kuchita bwino.
5. Sizimachepera ndi njira yokhazikitsa, ndipo njira yolowera kwa sing'anga ikhoza kukhala yovuta.
6. Palibe kugwedezeka, phokoso lotsika.
Makulidwe achipongwe ofewa
Chipata chofewa cha chipata cha mafayilo, valavu yamafakitale, chipata chofewa cha chipata chotseguka ndi ma rams okhazikika, chipata cha chipatacho chimatha kutsegulidwa ndikutsekedwa, sichingasinthidwe ndikusocheratu. Mbulayo ili ndi malo osindikizira awiri, pachipata chogwiritsidwa ntchito kwambiri chogwiritsidwa ntchito ndi mapidwe awiri amapanga ma cember a valavu, mainloni ndi ma dn1200, kutentha kwa bwino: ≤28 ≤200 ° C.
Mfundo
Chipata cha chipata cha wedgechipata chimavae ukhoza kupangidwa kwathunthu, womwe umatchedwa chipata chokhazikika; Itha kuphatikizidwanso mu nkhosa yamphongo yomwe imatha kupanga kuwonongeka pang'ono kuti ithandizire kutulutsa kwake kapangidwe kake kake kake kake kake kake kokomerako, komwe kumatchedwa ram.
Chisindikizo ChofewaMavesi pachipataamagawidwa m'magulu awiri: ndodo yotsegukachipata chofewandi chidindo chakuda chofewapachipata. Nthawi zambiri pamakhala ulusi wa trapezoidal pa ndodo yokweza, yomwe imasintha mawonekedwe mozungulira kudzera mu nati pakati pa nkhosa yamphongoyo ndi chitsogozo cholowera m'thupi la valavu, ndiye kuti, zojambula zojambula zoyendetsera tulo. Valavu ikatsegulidwa, pomwe kutalika kwa nkhosa ndi kofanana ndi 1: 1 nthawi ya valavu ya valavu, yotuluka yamadzi imasankhidwa kwathunthu, koma izi sizingayang'anitsidwe pakuchita opareshoni. Mukugwiritsa ntchito, imalembedwa ndi vertex ya tsinde, ndiye kuti, malo omwe sangatsegulidwe, monga malo ake otseguka. Pofuna kuwerengera zotsekemera chifukwa cha kusintha kwa kutentha, nthawi zambiri kumatsegulidwa kwa mawonekedwe a pex ndikubwereranso 1 / 2-1 kutembenukira ngati malo otseguka. Chifukwa chake, malo otseguka kwathunthu a valavu amatsimikizika ndi malo a nkhosa yamphongo (mwachitsanzo, stroke). Valavu yamtunduwu iyenera kuyikidwa molunjika pa mapaipi.
Zofunikira
1. Zolemba ndi magulu aMakulidwe ofewaayenera kukwaniritsa zofunikira za zikalata zopanga masipi.
2. Chitsanzo cha valavu yopanda pachipata iyenera kuwonetsa zofunikira za National. Ngati ndi muyezo wokhazikika, malongosoledwe oyenera a mtunduwo ayenera kuwonetsedwa.
3. Kupanikizika kwachipata chofewaPamafunika kuthamanga kwa ≥ Papaiperine, osakhudza mtengo, kukakamizidwa kuti valavu ikhale yokulirapo poyerekeza ndi kapamwamba kakang'ono ka Valails osagwira;
4..chipata chofewaIyenera kuwonetsa nambala ya dziko lonse malinga ndi iyo, ndipo ngati ili mu bizinesi, chikalata chabizinesi chikuyenera kuphatikizidwa ndi mgwirizano.
Chachiwiri, chipata chofewa cha chipata chofewa
1. Zinthu za thupi la valve zizikhala chitsulo, zimaponya chitsulo chosapanga dzimbiri, 316L, ndi kalasiyo ndi chidziwitso chenicheni champhamvu chamisala.
2. Mbali za tsinde iyenera kuyesetsa kusapanga dzimbiri (2cr13), ndipo valavu yayikulu iyeneranso kukhala chitsulo chopanda dzimbiri.
3. Nati imapangidwa ndi chimbudzi cha aluminiyamu kapena kutulutsa chimphepo chamkuwa, ndipo kuuma ndi nyonga ndi mphamvu ndizokulirapo kuposa gawo la valavu.
4. Kuumitsa ndi mphamvu za chinthu chotsatsira sikuyenera kukhala kwakukulu kuposa cha valavu ya valavu, ndipo payenera kukhala wopanda zitsulo za valavu ndi thupi la valavu momizidwa kumizidwa madzi.
5. Zinthu za kusindikizidwa
(1) Mitundu ya chisindikizo chofewapachipataMa S ndi osiyana, ndipo njira zosindikizira ndi zofunikira zakuthupi ndizosiyana;

Chachitatu, njira yogwiritsira ntchito Chisindikizo Chofewapachipata
3.1 Chitsogozo chotsegulira komanso chotseka cha chipata chofewa cha Phward Phwaut chikuyenera kutsekedwa.
3.2 Chifukwa valavu ya chibayo mu neip yotseguka nthawi zambiri imatsegulidwa ndipo idatsekedwa, kuchuluka kwa kutsegula ndi kutseka kosagwirizana sikuyenera kukhala kovuta kwambiri, ndiye kuti, valavu yayikulu kwambiri iyeneranso kukhala mkati mwa 200-600 kusinthana.
3.3 Kuti muthandizire kutsegulira kwa munthu m'modzi, kutseka kwa munthu m'modzi, kutseguka kwakukulu ndi torque yotseka kuyenera kukhala 240n-M pansi pa kupanikizika kwa mapaipi.
3.4 Kutseguka ndi kutha kwa chipata chofewa cha chipata chofewa kuyenera kukhala lalikulu teni, ndipo kukula kwake kuyenera kukhala koyenera, ndikuyang'aniridwa pansi, kuti anthu azitha kugwira ntchito molunjika kuchokera pansi. Mavavu okhala ndi disc disc sioyenera kugwiritsa ntchito pabwalo lapansi panthaka.
3.5 Onetsani gawo la kutseguka ndi kutseka kwa chisindikizo chofewapachipata

3.6 Ngati valavu yopanda pachipata imayatsidwa mozama, ndipo mtunda pakati pa makina ogwiritsira ntchito ndi gulu lowonetsera ndi nthaka ndi ≥ odzola, ndipo iyenera kukhazikika kuti anthu azitha kuwona ndikugwira ntchito kuchokera pansi. Ndiye kuti, kugwiritsa ntchito bwino ndi kutseka kwa valavu yomwe ili pachimake sioyenera kugwira ntchito mobisa.
Chachinayi, mayeso ogwiritsira ntchito Chisindikizo Chofewapachipata
4.1 Pamene valavu imapangidwa mumitundu ya lingaliro lina, bungwe lovomerezeka liyenera kupatsidwa mwayi woyesa kutsatira:
.
.valavukutseka mwamphamvu;
.
4.2 avalavuiyenera kuyesedwa motere musanachoke fakitaleyo:

Lachisanu, anti-yakunja ndi kunja kwa chipata chofewa
5.1 mkati ndi kunja kwa thupi la valavu (kuphatikizapo bokosi losinthasintha), choyamba Ngati nkovuta kwa epoxy epoxy epoxy stute pamatanthwe owonjezera, utoto wofanana wa epoxy uyeneranso kuthiridwa ndi kupopera mbewu.
5.2 mkati mwa thupi la valavu ndi ziwalo zonse za valavu zimafunikira kuti zikhale zotsutsana kwathunthu, sizikhala dzimbiri m'madzi, ndipo sipadzakhala kuwonongeka kwa electrochem pakati pa zitsulo ziwiri; Chachiwiri, mawonekedwe ake ndi osalala, kuti kukana madzi kumachepetsedwa.
5.3 Zofunikira zaukhondo za epoxy kapena utoto wa anti-orpis mu thupi la valavu ikhale ndi lipoti loyeserera kuchokera ku ulamuliro wolingana. Mphamvu zamankhwala ndi thupi ziyeneranso kukwaniritsa zofunika.
