Forged National Standard Globe Valve

Akatswiri ambiri a uinjiniya omwe amagula ma valve a mapaipi nthawi zambiri amakhala ndi nkhawa akakumana ndi mavuto. Amakumana ndi zinthu zokhala ndi miyeso yolakwika yomwe siyingayikidwe, kapena ma valve amawonongeka atangogwiritsa ntchito. Makamaka m'mikhalidwe yotsika kwambiri komanso yotentha kwambiri, nkhani zilizonse zimatha kukhala zovuta kwambiri. Valavu yathu ya Forged National standard globe idapangidwa makamaka kuti izikhala yovuta.

Ubwino waukulu

Thupi la valavu limapangidwa ndi A105N chitsulo chopanga kaboni, chomwe ndi chosiyana ndi matupi wamba oponyedwa. Kukonzekera kumathetsa zolakwika zosaoneka monga ma pores ndi mchenga muzitsulo, zomwe zimapangitsa kuti mapangidwewo akhale ochuluka kwambiri komanso kuwonjezereka kwachindunji kwa mphamvu yokakamiza. Valavu yapadziko lonse lapansi yokhazikika iyi imatha kupirira kutentha kwambiri kwa 425 ° C ndipo ili mkati mwa kukakamiza kwa PN16. Ngakhale kusinthasintha kwa kuthamanga mkati mwa mapaipi a nthunzi kumatha kuthandizidwa modalirika. Malo osindikizira amagwiritsa ntchito kuwotcherera kwa Samtler cobalt-based hard alloy, komwe sikutha kuvala komanso kusagwirizana ndi zokala. Ikhoza kupirira makumi masauzande ambiri otsegula ndi kutseka popanda kutayikira. Tsinde la valavu lakhala likuthandizidwa ndikuzimitsidwa ndi nitriding, zomwe zimapangitsa kuti zisawonongeke. Ngakhale ndi media zowononga pang'ono, sizowopa. Kuphatikiza apo, kulongedzako kumatha kusinthidwa pa intaneti popanda kuyimitsa ndikuchotsa valavu yonse, kupangitsa kukonza kukhala kosavuta.

Mfundo zaukadaulo

Iyi ndi J41H-16C DN25 PN16 yomwe anthu amakonda kufunsa. M'mimba mwake mwadzina ndi 25mm, kuthamanga mwadzina ndi 1.6MPa, valavu ya thupi ndi A105N, njira yolumikizira ndi yolumikizira flange, ndipo mapangidwe ndi kupanga zimagwirizana kwathunthu ndi muyezo wadziko lonse wa GB12235. Kutalika kwamapangidwe ndi miyeso ya flange zonse zimagwirizana ndi HG/T20592. Kuyesa ndi kuwunika kwadutsanso muyezo wa JB/T9092. Chigawo chilichonse chimayendetsedwa bwino, ndipo chikalandiridwa, chimatha kulumikizidwa mwachindunji ndi mapaipi popanda zosintha zilizonse. Komanso, valavu yathu ya National standard globe valve imatha kusinthidwa kukhala zida zosiyanasiyana malinga ndi momwe mumagwirira ntchito. Zitsulo zosapanga dzimbiri ndi aloyi zingagwiritsidwe ntchito. Ikhoza kukwaniritsa zofunikira zamitundu yosiyanasiyana.

Ubwino wampikisano

Poyerekeza ndi omwe akupikisana nawo, mafakitale ang'onoang'ono ambiri amagwiritsa ntchito ma valve oponya kuti apulumutse ndalama. Zitha kuwoneka zofanana, koma mkati mwake muli mabowo amchenga, ndipo zimatuluka zikagwiritsidwa ntchito kwa chaka chimodzi kapena ziwiri. M'mikhalidwe yopanikizika kwambiri, amakhala ndi ngozi zachitetezo. Njira yathu yopangira, ngakhale yokwera mtengo kwambiri, imakhala ndi mphamvu ya valavu yomwe imakhala nthawi 1.5 kuposa ya kuponyera. Kutalika kwa moyo kumatha kuwirikiza kawiri. Valavu yathu yapadziko lonse lapansi yokhazikika imatha kupirira kukokoloka kwa zinthu zomwe zili ndi tinthu tating'onoting'ono ndipo sizingasweka mosavuta. Pakapita nthawi, zimakhala zotsika mtengo ndipo sizifuna kusinthidwa pafupipafupi, zomwe zimasunga nthawi yopanga.

Chifukwa chiyani tisankha ife?

Ndife Huadu Valves, takhala tikugwira ntchito yopanga ma valve kwazaka zambiri. Zogulitsa zathu zonse zimapangidwa mufakitale yathu. Kuyambira kulowa kwa zopangira mpaka kumaliza kwa zinthu zomalizidwa, sitepe iliyonse imawunikidwa. Sitigwiritsa ntchito zinthu zosafunika kwenikweni ponyenga aliyense. Komanso, tili ndi zinthu zambiri zomwe zili m'sitolo. Mafotokozedwe a DN25 awa amatha kutumizidwa mwachindunji kuchokera kumalo osungiramo zinthu popanda kudikirira nthawi yayitali yopanga. Timaperekanso ntchito zosintha mwamakonda. Ma flange apadera ndi zida zapadera zimatha kupangidwa. Takhala tikugwira nawo ntchito zambiri zazikulu ndipo tadziwa zambiri.
