API Standard Forged Steel A182 F904L Mtundu Woyandama Wosindikizidwa Wosindikizidwa

The F904L forged zitsulo mpira valavu amasankhidwa, oyenera ndende zosiyanasiyana sulfuric asidi pansi pa 70 ℃, ndipo ali ndi kukana dzimbiri zabwino mu ndende iliyonse, kutentha, ndi asidi osakaniza formic asidi pansi pa kukakamizidwa wamba.

Monga chitsulo chosapanga dzimbiri, njira zosiyanasiyana zowotcherera zitha kugwiritsidwa ntchito powotcherera. Njira zowotcherera zomwe zimagwiritsidwa ntchito kwambiri ndi kuwotcherera kwa arc pamanja kapena kuwotcherera kwa inert. Ndodo yowotcherera kapena zitsulo zama waya zimatengera kapangidwe kazinthu zoyambira ndipo zimakhala ndi chiyero chapamwamba, chokhala ndi zofunikira zapamwamba za molybdenum kuposa zida zoyambira. Kutentha koyambirira sikofunikira musanayambe kuwotcherera, koma pozizira panja, kuti mupewe kusungunuka kwa nthunzi yamadzi, malo olowa kapena oyandikana nawo amatha kutenthedwa mofanana. Chonde dziwani kuti kutentha kwa m'deralo kuyenera kusapitirira 100 ℃ kupeŵa kudzikundikira kwa kaboni ndi intergranular dzimbiri. Pamene kuwotcherera, ndi m'pofunika kugwiritsa ntchito waya waung'ono mphamvu, mosalekeza ndi mofulumira kuwotcherera liwiro. Pambuyo kuwotcherera, chithandizo cha kutentha sikofunikira. Ngati chithandizo cha kutentha chikufunika, chiyenera kutenthedwa mpaka 1100-1150 ℃ ndiyeno kuzizira mofulumira.

Kuchita kwa Machining:

The Machining makhalidwe ofanana ndi zitsulo zina austenitic zosapanga dzimbiri, ndipo pali chizolowezi chomata chida ndi ntchito kuumitsa pa ndondomeko Machining. Zida zodulira zolimba zolimba zolimba ziyenera kugwiritsidwa ntchito, zokhala ndi mankhwala ndi mafuta a chlorine ngati choziziritsa kuzizira. Zida ndi ndondomeko ziyenera kukhazikitsidwa pa kuchepetsa kuuma kwa ntchito. Kuthamanga kwapang'onopang'ono ndi kuchuluka kwa chakudya kuyenera kupewedwa panthawi yodula.

- Kukula kuchokera 2 "mpaka 8" ( DN50mm kuti DN200mm).

- Magawo opanikizika kuyambira Class 150LB mpaka 600LB (PN10 mpaka PN100).

- Gawani kapangidwe ka thupi 2-pc kapena 3-pc.

- RF, RTJ, BW mapeto.

- Kubowola kwathunthu kapena kuchepetsedwa kwa bore.

- Mayendedwe oyendetsa amatha kukhala amanja, magetsi, pneumatic, kapena tsinde yopanda kanthu yokhala ndi ISO 5211 top flange yama actuators anu.

- Zipangizo wamba monga A105, A182 F304, A182 F316L, etc. ndi zipangizo apamwamba aloyi monga A182 F904L, A182 F51, A493 R60702, B564 N06600, B381 Gr. F-2 ndi ena.

Vavu yachitsulo yoyandama yachitsulo imakhala ndi voliyumu yaying'ono, kulemera kopepuka, kapangidwe kosavuta, ndi ntchito yoyandama yaulere, yomwe imatha kutsimikizira kusindikiza bwino; Pokhala ndi mawonekedwe ophatikizika ndikusintha mwachangu, valavu imatha kutsekedwa ndipo sing'anga yamapaipi imatha kudulidwa pozungulira madigiri 90; Kutalika kwa njira yozungulira ndi yofanana ndi ya payipi, yokhala ndi kukana otsika komanso kuthamanga kwambiri; Tsinde la valavu limayikidwa pansi, zomwe zimalepheretsa ngozi zomwe zimachitika chifukwa cha kuboola tsinde la valve ndikuwonetsetsa kugwiritsidwa ntchito moyenera. Makhalidwe apangidwe amtundu waukulu wa valavu yachitsulo yoyandama yachitsulo:

1. Mapangidwe a tsinde la valve yowonjezera

Tsinde la valavu la valavu yoyandama ya mpira limapangidwa ndi tsinde la valve yotalikirapo. Mapangidwe a tsinde la valavu yotalikirapo makamaka cholinga chake ndi kusunga bokosi la ma valve patali kutali ndi malo otentha kwambiri, kuwonetsetsa kuti bokosi lopakira ndi manja amphamvu zikugwiritsidwa ntchito pa kutentha kwabwino kuteteza kuzizira komanso kuzizira kwa opareshoni. Panthawi imodzimodziyo, imalepheretsanso kusindikiza kwa kusindikiza kuti kuchepe ndikutalikitsa moyo wake wautumiki.

2. Mapangidwe a Drip Board

Mapangidwe a mbale yodontha amatengedwa pamapangidwe a valavu yotalikirapo, yomwe ingalepheretse madzi a condensation kuti asafufutike ndikuyenderera kumalo otsekemera. Panthawi imodzimodziyo, imatha kutsimikizira bwino malo ogwirira ntchito a bokosi lolongedza katundu, potero kupewa zotsatira zoipa zambiri.

3. Mapangidwe oteteza moto

Chifukwa chakuti ma valve a mpira nthawi zambiri amagwiritsidwa ntchito pazida zoyaka komanso zophulika, mapangidwe oteteza moto ndi ofunikira. Chisindikizo chapawiri cha mphete yosindikizira yooneka ngati milomo ndi spiral bala gasket imagwiritsidwa ntchito polumikizana pakati pa chivundikiro cha valve ndi chivundikiro cha valve, ndipo mawonekedwe osindikizira awiri a mphete yosindikizira yooneka ngati milomo ndi kulongedza kwa graphite amagwiritsidwa ntchito pabokosi lonyamula. Moto ukayaka, mphete yosindikizira yooneka ngati milomo imasungunuka ndikulephera, ndipo chosindikizira cha gasket ndi graphite filler zimagwira ntchito yayikulu yosindikiza.

4. Anti static design

Kupyolera mukuchita bwino kwa akasupe odana ndi static ndi mipira yachitsulo, mpira, tsinde la valavu, ndi thupi la valve zimalumikizana wina ndi mzake, kupanga dera loyendetsa. Izi zitha kusamutsa zolipiritsa zopangidwa ndi valavu panthawi yotsegula ndi kutseka, potero kupewa kudzikundikira kwa magetsi osasunthika mumayendedwe a mapaipi ndikuwonjezera chitetezo chadongosolo. Kukana pakati pa tsinde la valavu, mpira, ndi thupi la valve kuyenera kuyesedwa pogwiritsa ntchito magetsi a DC osapitirira 12V. Kuyeza kuyenera kuchitidwa pa valavu youma musanayambe kuyesa kupanikizika, ndipo kukana sikuyenera kupitirira 10 ohms.
