Pneumatic Welded Atatu-Pie Mpira Mavavu: Odalirika M'mikhalidwe Yankhanza

Kapangidwe kolimba, kutentha kwambiri komanso kukana kuthamanga kwambiri: Kuunikira mozama kudalirika kwa ma valve opangidwa ndi pneumatic welded-piece-piece valve valves pansi pazovuta zogwirira ntchito.

Chidziwitso: M'mafakitale ambiri, ma valve a mpira akopa chidwi chambiri chifukwa cha magwiridwe awo abwino kwambiri osindikizira komanso mawonekedwe owongolera madzimadzi. Pepalali limayang'ana mozama za kudalirika kwa ma valve opangidwa ndi pneumatic welded atatu-piece mpira pansi pa zovuta zogwirira ntchito, ndikuwunika ubwino wake ndi momwe angagwiritsire ntchito pa kutentha kwakukulu ndi kupanikizika kwakukulu kupyolera mu kusanthula kwake, zipangizo ndi ntchito.

1. Mawu Oyamba

Ndi chitukuko chosalekeza chaukadaulo wopanga mafakitale, zofunikira pazida zowongolera zamadzimadzi zikuchulukirachulukira. M'madera a petroleum, makampani opanga mankhwala, mphamvu yamagetsi, ndi zina zotero, kutentha kwakukulu ndi kupanikizika kwakukulu kwa ntchito kumabweretsa mavuto aakulu pakugwira ntchito kwa zida za valve. Monga chida cha valve chomwe chimagwiritsidwa ntchito kwambiri m'malo ovuta, kudalirika kwa mavavu opangidwa ndi pneumatic welded atatu-piece kwakhala chidwi cha akatswiri amisiri ndiukadaulo. Pepalali lidzawunika mwatsatanetsatane kudalirika kwa ma valve opangidwa ndi pneumatic welded atatu-piece mpira pansi pa kutentha kwakukulu ndi malo opanikizika kwambiri kuchokera kuzinthu zamapangidwe, zipangizo ndi ntchito.

2. Makhalidwe amakhalidwe a pneumatic welded atatu-chidutswa mavavu mpira

2-1. Kapangidwe kazinthu zitatu

Valavu yopangidwa ndi pneumatic yopangidwa ndi zidutswa zitatu imagwiritsa ntchito kapangidwe ka magawo atatu, komwe ndi koyenera kuphatikizika ndi kukonza ma valve. Kutentha kwapamwamba ndi malo othamanga kwambiri, mapangidwewa amachepetsa kupsinjika maganizo chifukwa cha kusintha kwa kutentha kwa valve, komanso kumapangitsanso mphamvu zonse ndi kudalirika kwa valve.

2-2. Njira yolumikizira kuwotcherera

Valavu ya mpira wa ma pneumatic welded atatu imatenga njira yolumikizira yowotcherera, yomwe imalumikizidwa kwambiri ndi payipi ndipo imalepheretsa kutayikira. Komanso, kugwirizana kuwotcherera ali ubwino zotsatirazi:

(1) Kukaniza kuthamanga kwambiri: Kulumikizana kowotcherera kumatha kupirira kuthamanga kwambiri ndipo kuli koyenera kutentha kwambiri komanso kuthamanga kwambiri.

(2) Kukaniza bwino kwa dzimbiri: Kulumikizana kowotcherera kumakhala ndi kukana kwa dzimbiri ndipo kumatha kugwiritsidwa ntchito m'malo owononga kwambiri atolankhani.

(3) Kuyika kosavuta: Kulumikizana kowotcherera kumathandizira kukhazikitsa ndikuchepetsa ndalama zauinjiniya.

3. Kusankhidwa kwa zinthu za valavu ya mpira wa pneumatic welded wa magawo atatu

3-1. Vavu thupi zakuthupi

Pakutentha kwambiri komanso kupanikizika kwambiri, kusankha zinthu zamtundu wa valve ndikofunikira. Pneumatic welded atatu-piece ma valve mpira nthawi zambiri amagwiritsa ntchito kutentha kwambiri komanso kupanikizika kwambiri monga chitsulo chosapanga dzimbiri ndi chitsulo cha aloyi, chomwe chimakhala ndi kukana kwa dzimbiri komanso kutentha kwambiri.

3-2. Zida za mpira

Mpira ndi gawo lofunikira la valavu ya mpira, ndipo kusankha kwa zinthu zake kumakhudza mwachindunji ntchito yosindikiza komanso kulimba kwa valve. Ma valve opangidwa ndi pneumatic welded atatu-ball valves amagwiritsa ntchito zinthu zosagwira ntchito monga carbide ndi ceramics kuti zitsimikizire kudalirika ndi moyo wautumiki wa valve pansi pa kutentha kwakukulu ndi malo opanikizika kwambiri.

4. Magwiridwe ubwino wa pneumatic welded atatu-chidutswa mpira mavavu

4-1. Kuchita bwino kosindikiza

Valavu ya mpira wa pneumatic welded ya zidutswa zitatu imatenga mawonekedwe a mpira woyandama kuti agwirizane bwino pakati pa mpando wa valve ndi mpira, kuchepetsa bwino kutayikira. Pansi pa kutentha kwakukulu ndi kupanikizika kwakukulu, ntchito yake yosindikiza ndi yabwino kwambiri.

4-2. Kutentha kwambiri komanso kuthamanga kwambiri kunyamula mphamvu

Mpweya wopangidwa ndi pneumatic welded valavu yamagulu atatu amapangidwa ndi kutentha kwakukulu ndi zipangizo zothamanga kwambiri, zomwe zimatha kupirira kutentha kwakukulu ndi kupanikizika ndipo ndizoyenera kuntchito zovuta.

4-3. Zosavuta kugwiritsa ntchito

Valavu ya mpira wa ma pneumatic welded atatu imagwiritsa ntchito pneumatic actuator kuti ikwaniritse chiwongolero chakutali cha valavu ndikuchepetsa mphamvu yantchito ya woyendetsa. Panthawi imodzimodziyo, makina oyendetsa pneumatic ali ndi ubwino wothamanga mofulumira komanso kulondola kwapamwamba.

5. Mapeto

Kupyolera mu kuwunika mozama kwa kapangidwe kake, zida ndi magwiridwe antchito a valavu yamagulu atatu a pneumatic welded, pepala ili likunena izi:

5-1. The pneumatic welded atatu-chidutswa valavu mpira utenga atatu zidutswa structural kamangidwe ndi kuwotcherera njira yolumikizira, amene ali ndi makhalidwe amphamvu dongosolo ndi kukana kutentha ndi kuthamanga kwambiri.

5-2. Thupi la valve ndi mpira amapangidwa ndi kutentha kwakukulu ndi zipangizo zoponderezedwa kwambiri ndi zipangizo zosavala kuti zitsimikizire kudalirika ndi moyo wautumiki wa valve pansi pa ntchito zovuta.

5-3. Valavu ya mpira wa pneumatic welded yamagulu atatu imakhala ndi ntchito yabwino yosindikiza, kutentha kwambiri komanso kuthamanga kwamphamvu komanso kugwira ntchito kosavuta, ndipo imakhala ndi chiyembekezo chogwiritsa ntchito movutikira.

Mwachidule, kudalirika kwa valavu ya mpira wa pneumatic welded katatu pansi pa zovuta zogwirira ntchito kwatsimikiziridwa mokwanira, kupereka chitsimikizo champhamvu cha kupanga mafakitale. Muzochita zogwiritsidwa ntchito, valavu ya pneumatic welded yamagulu atatu iyenera kusankhidwa moyenerera ndikukonzedwa molingana ndi momwe ntchito imagwirira ntchito ndi makhalidwe apakati kuti zitsimikizidwe kuti zikugwira ntchito mokhazikika pansi pa kutentha kwakukulu ndi malo opanikizika kwambiri.
