1. Vavumfundo yosankha:
Valavu yosankhidwa iyenera kukwaniritsa mfundo zotsatirazi.
(1) Chitetezo ndi kudalirika kwa petrochemical, siteshoni mphamvu, zitsulo ndi mafakitale ena amafuna mosalekeza, khola, yaitali mkombero ntchito. Chifukwa chake, valavu iyenera kukhala yodalirika kwambiri, chifukwa cha chitetezo, osati chifukwa cha kulephera kwa valve komwe kumayambitsa chitetezo chachikulu ndi ngozi yovulaza munthu, kukwaniritsa zofunikira za chipangizo chautali wautali, kupanga nthawi yayitali kumapindulitsa, kuwonjezera, kuchepetsa kapena kupewa kutayikira komwe kumayambitsa. ndi valavu, pangani fakitale yoyera, yotukuka, HSE (ie, thanzi, chitetezo, chilengedwe) kasamalidwe.
(2) Kuti akwaniritse zofunikira za valavu yopanga ndondomeko ayenera kukumana ndi ntchito yapakati, kuthamanga kwa ntchito, kutentha kwa ntchito ndi zosowa za ntchito, zomwe ndizofunikira kwambiri pakusankha ma valve. Ngati kufunika valavu overpressure chitetezo udindo, kutulutsa owonjezera sing'anga, ayenera kusankha valavu chitetezo, valavu kusefukira, ayenera kuteteza ndondomeko ya sing'anga backflow, ayenera kugwiritsa ntchito valavu cheke, ayenera basi kuthetsa nthunzi chitoliro ndi zipangizo za condensate, mpweya ndi zina sangathe condensing. gasi, ndi kupewa nthunzi kuthawa, ayenera kusankha valavu kuda. Kuonjezera apo, pamene sing'angayo ikuwononga, zipangizo zabwino zokana zowonongeka ziyenera kusankhidwa.
(3) Pambuyo pa opaleshoni, kukhazikitsa, kuyang'anira (kukonza) kukonza valavu, wogwira ntchitoyo ayenera kudziwa bwino njira ya valve, zizindikiro zotsegulira, zizindikiro zowonetsera, zosavuta panthawi yake komanso motsimikiza kuthana ndi zolakwika zosiyanasiyana zadzidzidzi. Panthawi imodzimodziyo, mawonekedwe amtundu wa valve osankhidwa ayenera kukhala momwe angathere papepala la silinda, kuika, kuyang'anira (kukonza) kukonza bwino.
(4) Chuma Pamalo okhudzana ndi kugwiritsa ntchito mapaipi anthawi zonse, ma valve okhala ndi mtengo wotsika wopanga komanso mawonekedwe osavuta ayenera kusankhidwa momwe angathere kuti achepetse mtengo wa chipangizocho, kupewa kuwononga zida zopangira ma valve ndikuchepetsa mtengo wa kukhazikitsa ndi kukonza ma valve pambuyo pake.
2. Njira zosankhira mavavu:
Sankhani ma valve nthawi zambiri amatsatira zotsatirazi.
1. Dziwani momwe valavu imagwirira ntchito molingana ndi kugwiritsa ntchito valavu mu chipangizo kapena payipi yopangira. Mwachitsanzo, sing'anga yogwira ntchito, kuthamanga kwa ntchito ndi kutentha kwa ntchito, etc.
2. Dziwani kuchuluka kwa ntchito yosindikiza ya valve malinga ndi malo ogwirira ntchito, malo ogwirira ntchito ndi zofunikira za ogwiritsa ntchito.
3. Dziwani mtundu wa valve ndi kuyendetsa galimoto molingana ndi cholinga cha valve. Mitundu monga valavu yodula, valavu yoyendetsa, valavu yotetezera, ma valve ena apadera, etc. Njira yoyendetsa galimoto monga nyongolotsi ya nyongolotsi, magetsi, pneumatic, etc.
4. Sankhani molingana ndi magawo odziwika a valve. Kuthamanga mwadzina ndi kukula kwadzina kwa valve kudzagwirizana ndi chitoliro chokhazikitsidwa. Valavu imayikidwa mu payipi yopangira, kotero momwe ntchito yake ikuyendera iyenera kukhala yogwirizana ndi mapangidwe apangidwe a payipi. Pambuyo pa dongosolo lokhazikika ndi kukakamiza kwa chitoliro kutsimikiziridwa, kuthamanga kwadzina kwa valve, kukula kwadzina ndi mapangidwe a valve ndi kupanga mapangidwe angatsimikizidwe. Ma valve ena amatsimikizira kukula kwadzina kwa valve malinga ndi kuchuluka kwa kuthamanga kapena kutulutsa kwa valve panthawi yovomerezeka yapakati.
5. Dziwani mawonekedwe a kugwirizana kwa valavu kumapeto kwa valavu ndi chitoliro molingana ndi zochitika zenizeni zogwirira ntchito ndi kukula kwadzina kwa valve. Monga flange, kuwotcherera, kopanira kapena ulusi, etc.
6. Dziwani mawonekedwe ndi mawonekedwe a mtundu wa valve malinga ndi malo oyikapo, malo oyikapo, ndi kukula kwadzina kwa valve. Monga valavu yachipata chamdima, valavu yapadziko lapansi, valavu ya mpira, ndi zina zotero.
7. Malinga ndi mawonekedwe a sing'anga, kuthamanga kwa ntchito ndi kutentha kwa ntchito, kusankha kolondola ndi koyenera kwa chipolopolo cha valve ndi zipangizo zamkati.
Komanso,Malingaliro a kampani Tianjin Tanggu Water Seal Valve Co., Ltd. ndiukadaulo wapamwamba zotanuka mpando valavu kuthandiza mabizinesi, mankhwala ndi zotanuka mpando wafer butterfly valavu,valavu ya butterfly, valavu ya butterfly yachiwiri ya flange, valavu yagulugufe yapawiri ya flange eccentric, valve balance,valavu yowunikira mbale ziwiri, Y-Strainer ndi zina zotero. Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
