Mapangidwe a zitsulo kupita kuzitsulo amakhala valavu ya mpira makamaka imakhala ndi thupi la valve, mpira wa valve, mphete yosindikiza, tsinde la valve ndi kulongedza. Pakati pawo, mpira wa valve ndi mphete yosindikizira ndi zigawo zikuluzikulu, zomwe nthawi zambiri zimapangidwa ndi zipangizo zolimba kwambiri komanso zowonongeka zowonongeka monga zitsulo zosapanga dzimbiri kapena zitsulo zamtengo wapatali. Maonekedwe a mpira ndi mphete yosindikizira ndizokhazikika bwino komanso zowumitsidwa kuti zitsimikizire kuti mpirawo umakhala wokwanira pakati pa mpira ndi mphete yosindikizira kuti akwaniritse kusindikiza kwabwino.

Poyerekeza ndi zofewa losindikizidwa mavavu mpira, zitsulo kwa zitsulo anakhala mpira mavavu osati ndi makhalidwe otsika kukana madzimadzi, mwamsanga ndi yabwino kutsegula ndi kutseka, ntchito bwino kusindikiza, moyo wautali utumiki, kudalirika mkulu, ndi kuyika mosavuta ndi zipangizo zamagetsi ndi pneumatic, komanso amatha kutengera kusiyanasiyana kwa kutentha ndi minda yamadzimadzi. Choncho, amagwiritsidwa ntchito kwambiri poyendetsa mapaipi. Mpira ndi mpando wa valve yotsekedwa mwamphamvu zonse zimapangidwa ndi zitsulo zachitsulo, ndipo kusindikiza kosindikizidwa kopangidwa ndi zitsulo ndi zitsulo kumatchedwa kuti chisindikizo cholimba. Mapangidwe a mavavu a mpira osindikizidwa mwamphamvu ayenera kutsatira API 6D. Amapangidwa makamaka ndi valavu thupi, mpando valavu, sphere, valavu tsinde, ndi galimoto chipangizo.

Nthawi zina pamwamba pa 100 ℃, gwiritsani ntchito chosindikizira chosindikizira. Mpando wa mpira ndi valavu ndi wosindikizidwa mwamphamvu. Kupanikizika kosasunthika pamwamba pa mpando wa valve ndi tsinde la valve zimasindikizidwa ndi graphite kulongedza. Chotsani zopondereza pakati pa tsinde la valavu ndi chiwombankhanga, komanso pakati pa bwalo ndi mbale yothandizira. Gland flange ndi mbale yothandizira ndi nitrided. Kapangidwe kameneka kamakhala kosawerengeka ndi kutentha kwa ntchito ndipo nthawi zambiri kumatha kugwiritsidwa ntchito mpaka 500 ℃;

Pamalo omwe kutentha kumakhala kochepa kapena kofanana ndi 100 ℃, gwiritsani ntchito mawonekedwe osindikizira a O-ring. Mapangidwe a valavu yokhazikika ya mpira nthawi zambiri amakhala ofanana ndi a valve okhazikika a mpira (chida chojambulira mafuta chimafunika pampando wa valve ndi tsinde la valve). Kuthamanga kwa static pampando wa valve ndi tsinde la valve zonse zimasindikizidwa ndi zisindikizo za O-ring, kupatula kuti mpira ndi mpando wa valve ndizosindikizidwa mwamphamvu. Pure PTFE thrust pads amagwiritsidwa ntchito pakati pa tsinde la valve ndi gland flange, komanso pakati pa mbale yothandizira ndi gawolo.

Mapangidwe osindikizira a valavu yosindikizidwa yolimba yokhala ndi chisindikizo chonyamulira amakhala ndi mpando wa valve zotanuka, ndipo gulu la akasupe limakonzedwa mozungulira gawo la gawo la valavu kuti nthawi zonse mpando wa valve ukukanikiza mpirawo ndikukwaniritsa pre. boma lomangika. Pamene kuthamanga kwamadzimadzi pampando wa valve kumakhala kotsika kwambiri, kumadalira kukankhira kasupe; Pamene kuthamanga kwamadzimadzi kumakhala kwakukulu, mphamvu yosagwirizana ndi mphamvu yamadzimadzi pampando wa valve imatsimikizira kusindikiza. Malo oponderezedwa a mpando wa valve ndi aakulu kuposa malo oponderezedwa a mpando wa valve. Mphamvu yosakhazikika yopangidwa ndi kuthamanga kwamadzi pampando wa valve yotanuka imakankhira mpando wa valve kutsogolo kupita kumalo, kukanikiza ndi kusunga chisindikizocho. Kuthamanga kwamadzimadzi kumakwera, kumakhala bwino kwambiri kuti asindikize chisindikizo ichi.

Zina Zowonjezera

Nthawi zambiri pamakhala mitundu iwiri yamapangidwe a mavavu omata omata osavala: mpira woyandama ndi mtundu wokhazikika wa mpira. Mosasamala mtundu wa kapangidwe kake, m'malo ogwiritsidwa ntchito movutikira, ndikofunikira kuletsa kudzikundikira kwa zida zam'chipinda cha masika pampando wa valve zotanuka kuti valavu isagwire bwino ntchito, zomwe zimapangitsa kuti ma torque achuluke kapena "kugwedezeka" kwa valavu. valavu. Kuti izi zitheke, wopangayo wapanga mavavu odzitchinjiriza odzitchinjiriza (mtundu woyandama) ndi mavavu osamva a mpira (mtundu wokhazikika), omwe amathetsa vutoli.

Zitsulo zolimba zosindikizidwa mpira zimakhala ndi khalidwe lodziyeretsa. Mpando wa vavu woyandama kumtunda wapangidwa ngati njira yodzitchinjiriza yokhala ndi ntchito yowomba. Pakutsegulira ndi kutseka, valavu imatha kudalira kukakamizidwa kwa sing'angayo kuti iwombe ndikusesa zinthu zomwe zasonkhanitsidwa mu kasupe ndi chipinda cha valve, kuti tipewe tinthu tating'ono ting'onoting'ono ting'onoting'ono m'chipinda cha masika ndikupangitsa "kutseka". "zodabwitsa, zomwe zimakhudza ntchito yachibadwa ya valve; Mpando wa valve yosindikizira ndi njira yosinthika; Onjezani mapepala awiri odzipaka okha pa tsinde la valve kuti muchepetse torque ya ma valve.

Mpando wa valavu yazitsulo zolimba zomata mpira umatengera kapangidwe ka "kuwongolera", ndipo thanki yonyowa imapangidwira kutsogolo kuonetsetsa kuti valavu imatha kuyika zida kutsogolo kwa chipinda cha masika pakagwiritsidwa ntchito, osakhudza zachilendo. kubwerera kwa mpando wa valve.

Mapulogalamu

Ma valve otsekedwa ndi zitsulo, omwe ali ndi ubwino wake wapadera, amagwiritsidwa ntchito kwambiri m'makampani a malasha, polysilicon, kuyenga mafuta, nsanja za m'mphepete mwa nyanja, makina opangira magetsi opangira magetsi, ndi magetsi. Pazinthu zomwe zimafuna kutsekedwa mwamphamvu, kutentha kwakukulu ndi kusiyana kwakukulu, kutsegula ndi kutseka mwamsanga, ndi zofalitsa zomwe zimakhala ndi tinthu tating'onoting'ono tolimba, zitsulo zolimba zosindikizidwa za mpira ndizo mtundu wa valve womwe umakonda. Komabe, mavavu achitsulo osindikizidwa olimba nthawi zambiri amakhala ndi zovuta monga moyo wocheperako, kutayikira mkati, ndi kupanikizana (kapena kupanikizana) panthawi yogwira ntchito. Poyang'anizana ndi zomwe zimafunika kuvala kwambiri komanso kukokoloka kwamphamvu, mavavu a mpira osamva kuvala amayenera kukonzedwa molingana ndi chithandizo cholimba cha pamwamba, kapangidwe kake, kusankha zigawo, ndi kukonza.
