1. Bupanduluzi bwantalisyo abupange
Ivalvu iijisi ntalisyo iiteteete (alimwi iizyibidwe kuti "ivalvu yabutterfly iili akati-kati") nivalvu iizunguluka iikonzya kuzunguluka kota yakapangwa kuti ibelesegwe kujala/kuzima naa kuchesya kweenda kwamaanzi mumapayipi. Zibeela zyakwe zipati zibikkilizya:
Bupange bwa Concentric: Cisiko ca valve, disiki, acuuno ziliimpene aakati-kati komwe, kupa kuti kube bupange buuba-uba alimwi buli kabotu.
Nzila Yakujala Iiteteete: Chijazyo cha elastomeric (nkokuti, raba, EPDM, NBR) chibikkilizyidwe mumubili wa valve naakuti chibbula, kupa kuti chikwabilizyo chiyumu kuchitila kuti kutabi kuvwundauka.
Mamanino aajisi ntambo: Ivalvu ilijisi zijatikizyo zijatikizyidwe, ikuzumizya kubikka chakufwambaana mumapayipi aatobela zyeelelo zilimbuli ANSI, DIN, naa JIS.
2.Zibeela Zipati
3. Njiisyo yakubeleka
Busena bwakujalula: Disiki ilazungaana 90° kuti kweendelane anzila yakuzuza, ikucheesya kuseluka kwanguzu akuzumizya kweenda koonse.
Busena Bwakujala: Disiki lilajokela musule kuti lijate chijazyo chiteteete, mpawo lipa kuti lijale loko. Bupange bwa concentric buyeeme akusanduka kwachikwabilizyo kuchitila kuti chikwabilile, kupa kuti chibelesegwe kabotu mumilimo iitakatazyi pe.
4. Zibeela zipati abubotu
Kujala chakusinizya: Zijala ziteteete zipa kuti kutabi kuvwundauka, kanjikanji zilazuzikizya zyeelelo zyakujala mabbiza (nkokuti, ANSI B16.104 Class VI, ISO 15848-1).
Kubelesya Nguzu Ziniini: Bupange buli akati-akati antoomwe akujala kwanguzu kucesya kuzwangana, kupa kuti kube kuuba kubelesya amaanza naa kubelesya zibelesyo zitakatazyi pe.
Nchintu chifwiifwi mpawo nchuuba: Kweezyanisya amavalvu aamulyango naakuti globe, mavalvu aabutterfly aali akati-akati masyoonto alimwi ngaubauba kubikka mumasena masyoonto.
Tazibelesyi mali manji: Bupange buuba-uba akubelesya zintu zisyoonto zipa kuti kazikonzya kuula muzintu ziyandikana zyakweendelezya kweenda kwamaanzi.
Kweezyanisya kwazibelesyo zyiingi: kweelela mumaanzi, muuya, mafuta, zintu zitanyonyooki, antoomwe azibelesyo zyamabwe (zijisi zintu zitakonzyi kubola).
5. Zitondezyo zyabusongo
Kupima kwakusinkilila: Kanjikanji nkusinkilila kwaansi kusikila aakati-akati (nkokuti, PN6–PN16 / Chikolo 125–Ikkilasi 150).
Kupya:
Ma elastomers (nkokuti, NR, EPDM): -10°C kusikila ku 90°C (14°F kusikila ku 194°F).
Zijazyo zyakupya kapati (nkokuti, Viton®, PTFE): -20°C kusikila ku 150°C (-4°F kusika ku 302°F).
Kutobelezya zyeelelo:
Bupange: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Kusunka: API 598, (kusunkwa kwakuzwa).
6. Zibelesyo
Kujala kuteteete kwamavalvu aajisi ntalisyo D341X-16Qzibelesyegwa kapati muli:
Kupa maanzi akugwisya maanzi: Nzila zyamaanzi zyamunzi, zibelesyo zyakusalazya tombe, anzila zyakutilila.
Nzila zya HVAC: Kweendelezya muya, maanzi, naa busi mukupyasya, kuyoya, akutontozya muya.
Makwebo aazyakulya azyakunywa: Kubelesya bulondo bwa FDA-compliant seals (nkokuti, EPDM azyakuvwumba zyakulya).
Nzila Zyakubelesya Zyoonse: Kubelesya maanzi aataboli mumakkampani aapanga misamu, mapepa, alimwi amisamu (yakubelesya misamu iikola luzutu).
Kuyaka bwamulwizi abwato: Kujala/kuzima mumaanzi aalwizi naakuti mumabbanga (azibelesyo zitakonzyi kubola).
7. Zilebyo azintu zyeelede kuyeeyelwa
Milawo Yakusinikizyigwa aKupya: Tazyeelede pe kubelesyegwa muchiindi chilamfu (nkokuti, >PN16) naakuti kupya kapati (nkokuti, busi buli atala a 150°C).
Ntenda zyakubola: Zibeela zyabutale (nkokuti, zintu zyabutale) zilakonzya kubola mumasena aakatazya; sumpula kuya ku nsimbi zitakwe nsimbi naakuti zintu zijisi penti mubukkale bukatazya.
Zibelesyo Zyakubelesya: Zisinkilizyo zitete zilakonzya kubola akufwambaana amaanzi ajisi tuzunda; yeeyela mavalvu aabutterfly aasimide naakuti zimwi zikwabilizyo.
Kusala Chakubelesya: Kumavwili mapati naakuti kubeleka chiindi chiingi, kobelesya zibelesyo zya pneumatic/hydraulic kuchitila kutabilila kukatazyigwa amaanza.
8. Kubikka akubamba
Kubikka:
Bona kuti ma flanges ali kabotu mpawo ma bbaluti alijatikizyidwe kabotu kuchitila kutabilila kuvwundauka.
Kozyiba kubikka vvalavu muchiindi chakukatazyigwa kapati.
Kubamba:
Chiindi choonse kolanga chisinkilizyo kuti naa chakazwa naa kutyoka, ikapati muchiindi chilamfu.
Sanzya chisiko aachituta chiindi achiindi kuchitila kuti kube kubeleka obotu.
Bikka chisinkilizyo kuti kwaba kuvwundauka; amwi mabambe alazumizya kuchincha chisinkilizyo kakunyina kugwisya vvalavu kuzwa mumupayipi.
9. Nzila zyakusala basikusambala azyakusambala
Kusinizya zintu: Bona kuti zikwabilizyo zilazuzikizya zyeelelo zyamakkampani (nkokuti, FDA yazyakulya, ATEX yabusena bukonzya kupwasuka).
Nzila zyakulisalila: Bamwi basambazi balapa zintu zitazungaani, zintu zikwabilila mulilo, naa zintu zimwi zyakuvwumba (nkokuti, epoxy, PTFE) zyakubelesya munzila imwi.
Mamanino
Kujala kuteteete kwamavalvu aajisi ntalisyoninzila iitayandiki mali manji, iisyomeka yakweendelezya kweenda kwanguzu zyaansi kusikila akati-akati muzintu zitayandiki kapati. Kuubauba kwazyo, kujala kabotu, akuubauba kwakubamba zipa kuti zibelesyegwe kapati mumaanzi, HVAC, anzila zyamafakitali. Kubusena bukatazya, kuchincha kuya kuzintu zitaambiki naakuti zintu zibotu loko zilalumbaizyigwa. Lyoonse kolanga-langa zintu zyakubelesya, bukkale bwakubeleka, alimwi akutobela milawo kutegwa usale vvalavu iili kabotu kweelana azintu nzyoyanda.
