Gawo lotsegula ndi lotseka la valve yotsekera pachipata ndi mbale yachipata. Mayendedwe a kayendedwe ka chipata mbale ndi perpendicular kwa malangizo a madzimadzi. Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, koma siyingasinthidwe ndikugwedezeka. Nkhope ziwiri zosindikizira za valve ya pachipata zimakhala ngati mphero. Mphepete mwa mphero zimasiyanasiyana ndi magawo valavu, kawirikawiri 50, ndi 2 ° 52 'pamene sing'anga kutentha si mkulu. Valve ya chipata cha wedge imatha kupangidwa yonse, yotchedwa chipata cholimba; Itha kupangidwanso kukhala chipata chomwe chimatha kutulutsa trace deformation kuti ipititse patsogolo ukadaulo wake ndikupanga kupatuka kwa kusindikiza pamwamba pa ngodya pokonza. Chipata chamtunduwu chimatchedwa chipata chotanuka.

Gulu la mavavu a chipata chachitsulo choponyedwa
Kutaya zitsulo pachipata valavu: malinga ndi zinthu, pali mpweya zitsulo chipata valavu, zosapanga dzimbiri valavu pachipata, otsika aloyi zitsulo chipata valavu (kutentha kugonjetsedwa ndi chromium molybdenum zitsulo ndi wa gulu ili), otsika kutentha zitsulo chipata valavu, etc.
Mitundu yosiyanasiyana ya mavavu a chipata chachitsulo imakhala ndi magulu osiyanasiyana achitsulo omwe amagwiritsidwa ntchito motere:
1. Mpweya wa carbon zitsulo pachipata valavu kuponyera makalasi ndi: WCA, WCB, WCC, LCB, etc. Ntchito kutentha -46 madigiri ~425 madigiri.
2. Zosapanga dzimbiri pachipata valavu castings: 301 zitsulo zosapanga dzimbiri, CF8 zitsulo zosapanga dzimbiri (logwirizana ndi kupeka 304 zitsulo zosapanga dzimbiri), CF8M zitsulo zosapanga dzimbiri (logwirizana ndi kupanga 316 zitsulo zosapanga dzimbiri), etc. Ntchito kutentha -198 madigiri ~ 816 madigiri.
3, otsika aloyi zitsulo lagawidwa mu kutentha aloyi zitsulo ndi wangwiro otsika aloyi zitsulo, pakati pa kutentha aloyi zitsulo zambiri amati chromium molybdenum zitsulo.
Chromium molybdenum zitsulo pachipata valavu kuponyera makalasi: ZG1Cr5Mo, ZG15Cr1MoV, ZG20CrMoV, WC6, WC9, C12A ndi zina zotero. Kutentha kokwanira 550 madigiri mpaka 750 madigiri.
Kutentha komwe kumagwiritsidwa ntchito pamtundu uliwonse wazinthu kumakhala kosiyana, kutengera momwe ntchito ikugwirira ntchito.

Magudumu am'manja, chogwirizira ndi njira zotumizira siziloledwa kugwiritsidwa ntchito pokweza, ndipo kugunda ndikoletsedwa.
Mavavu a zitseko ziwiri ayenera kuikidwa molunjika (mwachitsanzo, tsinde pamalo ofukula ndi gudumu lamanja pamwamba).
Ma valve a zipata okhala ndi ma bypass valves ayenera kutsegulidwa musanatsegule (kuwongolera kusiyana kwapakati pakati pa kulowa ndi kutulutsa ndikuchepetsa mphamvu yotsegulira).
Valve yachipata yokhala ndi makina oyendetsa iyenera kukhazikitsidwa molingana ndi malangizo a mankhwalawa.
Mavavu opaka mafuta osachepera kamodzi pamwezi ngati amagwiritsidwa ntchito mobwerezabwereza.
Kuthamanga kwa mapaipi, kuthamanga, kuwongolera kutentha kwamitundu yosiyanasiyana yama makina opanga mafakitale. Mwachitsanzo: mphamvu yamagetsi, zitsulo, petrochemical, kuteteza chilengedwe, kasamalidwe ka mphamvu, dongosolo chitetezo moto ndi zina zotero. Kwa nthawi yayitali, ma valve omwe amagwiritsidwa ntchito pamsika nthawi zambiri amakhala akuchucha kapena dzimbiri. Mabizinesi ena amayambitsa ukadaulo wapamwamba kwambiri waku Europe wopangira mphira ndi ma valve kuti apange valavu yosindikizira yapampando, yomwe imagonjetsa valavu yachipata chosasindikiza bwino, dzimbiri ndi zolakwika zina. Valavu yosindikizira yapampando yosindikizira imagwiritsa ntchito mbale zotanuka pachipata kuti ipangitse chipukuta misozi pang'ono kuti ikwaniritse bwino kusindikiza. Valavu ili ndi ubwino wosinthira kuwala, chisindikizo chodalirika, kukumbukira bwino zotanuka komanso moyo wautumiki.
"Zoyipa" zingapo zomwe zimawopseza malo osindikizira a mavavu osapanga dzimbiri
Valavu yachitsulo chosapanga dzimbiri imatanthawuza kugwiritsa ntchito zida zosapanga dzimbiri zopangidwa ndi ma valve. Valve ndi gawo lowongolera pamapaipi operekera madzimadzi. Amagwiritsidwa ntchito kusintha gawo la tchanelo ndi njira yoyendetsera sing'anga. Lili ndi ntchito za kusokoneza, kudula, kuwongolera, kugwedeza, cheke, shunt kapena kuchepetsa kupanikizika kwa kusefukira. Mavavu owongolera madzimadzi amachokera ku mavavu osavuta a globe kupita ku mavavu omwe amagwiritsidwa ntchito m'makina ovuta kwambiri owongolera amitundu yosiyanasiyana komanso mawonekedwe.
Chitsulo chosapanga dzimbiri valavu ndi chitoliro kapena makina zida kugwirizana ndi 304 zosapanga dzimbiri flange kugwirizana, omwe amadziwika kuti 304 zosapanga dzimbiri flange kugwirizana.
Vavu yachitsulo chosapanga dzimbiri imatenga zinthu zachitsulo zosapanga dzimbiri zokhala ndi chogwirira, turbine, pneumatic, kapangidwe kamagetsi kamagetsi, kusintha kosinthika komanso kuwala. Kapangidwe kakang'ono, kulemera kopepuka, kosavuta kusunga kutentha, kosavuta kukhazikitsa. Njira yolumikizira: kuwotcherera, ulusi, flange kuti ogwiritsa ntchito asankhe. Ili ndi ntchito yabwino yosindikiza komanso kukana dzimbiri. Mavavu zitsulo zosapanga dzimbiri akupitiriza kuyamwa ukadaulo wapamwamba wakunja, kuphatikiza ndi momwe zinthu ziliri pakukula kwapakhomo, kupita kunyumba m'malo mwa kunja. Amagwiritsidwa ntchito mu gasi, petroleum, kutentha, mankhwala ndi thermoelectric pipe network ndi madera ena apaipi apamtunda wautali.
Pakadali pano pakugwiritsa ntchito mavavu achitsulo chosapanga dzimbiri, valavu ya chitsulo chosapanga dzimbiri, valavu yachipata, valavu yapadziko lonse pamsika imagwiritsa ntchito zodziwikiratu.
Poyerekeza ndi mafakitale achikhalidwe, chifukwa cha zofooka zamapangidwe, sizoyenera kukana kutentha kwambiri, kuthamanga kwambiri ndi kukana dzimbiri, kukana kuvala ndi mafakitale ena. Kuwonongeka kwa mitundu yonse ya zinthu kumagawidwa m'magulu awiri a zowonongeka zopangidwa ndi anthu komanso zachilengedwe, valavu yachitsulo chosapanga dzimbiri ndizosiyana, kuwonongeka kwachilengedwe, ndi kuvala kwa valve pansi pa ntchito yabwino. Ndiko kuwonongeka komwe kumachitika chifukwa cha dzimbiri kosalephereka ndi kukokoloka kwa malo osindikizira ndi sing'anga, yomwe imagawidwa kwambiri m'magawo awa:
1. Kuyika ndi kukonza kosakwanira
Izi zimatsogolera ku ntchito yachilendo ya malo osindikizira, ndipo valavu imayenda ndi matenda, zomwe zimapangitsa kuti pakhale kukakamizika ndi kuwonongeka kwa malo osindikizira. Ntchito yaikulu ndi yakuti valavu siidasankhidwe molingana ndi momwe ntchito ikugwirira ntchito, ndipo valavu ya truncation imagwiritsidwa ntchito ngati valve throttle valve, yomwe imapangitsa kuti kusindikiza kusindikizidwe kumakhala kwakukulu kwambiri ndipo kusindikiza kumathamanga kwambiri kapena kusindikiza sikovuta, kotero. kuti malo osindikizira amakokoloka ndi kutha.
2. Kusankhidwa kolakwika ndi ntchito yosayenera
Makamaka osati molingana ndi momwe ntchito ikugwirira ntchito ndikusankha valavu, monga valavu ya truncation pamene valavu yotsekemera ikugwiritsidwa ntchito, zomwe zimapangitsa kuti kusindikiza kusindikizidwe kumakhala kwakukulu kwambiri ndipo kusindikiza mofulumira kwambiri kapena kusindikiza sikuli kovuta, kotero kuti kusindikiza pamwamba ndi kukokoloka ndi kuvala. Kapena valavu yachitsulo yotayidwa imagwiritsidwa ntchito muzofalitsa zowononga, kapena valavu yosagwira kutentha imagwiritsidwa ntchito kutentha kwambiri. Kapena chinthu chosindikizira chambiri chimagwiritsidwa ntchito pamalo omwe ali ndi zonyansa zambiri komanso kutentha kwambiri.
3. Kukokoloka kwapakati
Ndi zotsatira za kuvala, kutsuka ndi cavitation ya kusindikiza pamwamba pamene sing'anga ikugwira ntchito. Pa liwiro linalake, tinthu tating'onoting'ono ta planktic mkatikati timaphwanya kusindikiza pamwamba, ndikuwononga m'deralo. Sing'anga yothamanga kwambiri imatsuka mwachindunji malo osindikizira, kuchititsa kuwonongeka kwanuko. Sing'angayo ikasakanizidwa ndi kutenthedwa, kuphulika kokwiyako kumakhudza pamwamba pa malo osindikizira, kuwononga malo. Kukokoloka kwa sing'anga pamodzi ndi kusinthasintha kwa kukokoloka kwa mankhwala kudzakokolola kwambiri malo osindikizira.
4. Kukokoloka kwa electrochemical
Kusindikiza pamwamba kumakhudzana ndi mzake, kusindikiza pamwamba kumakhudzana ndi thupi losindikiza ndi thupi la valve, komanso kusiyana kwapakati pa sing'anga, kusiyana kwa ndende ya okosijeni ndi zifukwa zina, zidzatulutsa kusiyana kwakukulu, kukokoloka kwa electrochemical. , zomwe zimapangitsa kukokoloka kwa mbali ya anode ya malo osindikizira.
