Mndandanda wa ma valve oyandama
- ARAN ili ndi ma valve oyandama oyandama amitundu yosiyanasiyana, zida ndi mawonekedwe abwino komanso okwera mtengo pamapaipi otseka.Mapangidwe amtundu wa mpira woyandama amagwiritsidwa ntchito pakukula kwazing'ono kapena mavavu otsika otsika, ali ndi mawonekedwe achitsulo kapena opangidwa ndi chitsulo, mawonekedwe amtundu wa valavu ya 2 ma PC kapena 3pcs.Poyerekeza ndi valavu ya mpira wa trunnion, valavu ya mpira woyandama nthawi zonse imakhala mavavu ang'onoang'ono osaposa mainchesi 6.
- Flange yomalizaKuthamanga kwa valve yoyandama komwe kulipo:
- 150LBS kukula 1/2IN~8IN,300LBS kukula 1/2”~6IN
- 600LBS size1/2 IN~3IN,900~1500LBS size1/2IN~2IN.
- SW/NPT/BW/NIPPLE mapetoKuthamanga kwa valve yoyandama komwe kulipo
- 150LB~800LBS kukula 1/2IN~2IN.
- 900 ~ 2500LBS kukula 1/2IN~11/2IN.
- valavu ya mpira yoyandama ndi chiyani?
- Vavu yoyandama ya mpira imatanthawuza kuti mpira ukuyandama mu kapangidwe ka chipinda cha vavu, mpando umakhazikika mthupi, ndipo mpirawo umathandizidwa ndi tsinde.Kulumikizana kwa tsinde ndi mpira mu quarter turn movement.Mpira woyandama pakati pa mipando ya valavu ndikugwiritsa ntchito mzere wapakati wapakati kukankhira mpirawo pansi pamtsinje kuti utseke bwino ndi valavu yosindikizidwa.Valavu imatha kulumikizidwa m'njira ziwiri, koma imakhala yolimba kwambiri.
- Kodi ma valve oyandama a mpira ndi chiyani?
- Mpira woyandama ndi valavu yaying'ono yaying'ono komanso valavu yotsika ya torque.
- Chovala cha valavu chimakhala ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo, thupi la valve nthawi zambiri limakhala zidutswa ziwiri kapena zitatu, ndi thupi la mgwirizano.
- ● Mapangidwe odalirika osindikizira mpando
- Vavu ya mpira woyandama woyandama imatengera mawonekedwe osindikizira mipando yofewa.Kupanikizika kwapakati kukakhala kochepa, malo olumikizirana ndi mphete yosindikizira ndi mpira amakhala ochepa, koma malo olumikizirana ndi mpira amapeza chiŵerengero chapamwamba chosindikizira kuti atsimikizire kusindikiza kolimba.Kuthamanga kwapakati kukakhala kokulirapo, malo olumikizirana a chisindikizo ndi mpira amakhala ochulukirapo, ndipo mphete yosindikizira imatha kupirira kukankhira kwapakatikati popanda kuonongeka.
- ●Mapangidwe Osatentha Moto pampando, flange yapakati ndi tsinde
- Pakayaka moto, mphete yapampando yopangidwa ndi PTFE kapena zinthu zina zopanda zitsulo zidzawonongeka kapena kuonongeka pansi pa kutentha kwakukulu ndikuyambitsa kutayikira kwakukulu.Mphete yosindikizira yotchinga moto imayikidwa pakati pa mpira ndi mpando kotero kuti mpando wofewa wa valavu ukayaka, sing'angayo imakankhira mpirawo mwachangu kupita ku mphete yosindikizira yachitsulo kuti ipange chitsulo chothandizira kupanga chitsulo chosindikizira, chomwe chimatha kuwongolera bwino kutayikira kwa valve.Komanso, pakati flange kusindikiza gasket amapangidwa ndi zitsulo bala gasket, amene angathe kuonetsetsa kusindikiza ngakhale kutentha kwambiri.Mapangidwe amagetsi osayaka moto a valve yoyandama amagwirizana ndi zofunikira mu API 607, API 6FA, BS 6755 ndi JB/T6899 etc.
- Mkuyu. Mapangidwe odalirika a mpando wosindikizira & Kapangidwe kamangidwe kakapangidwe kamoto pampando, flange yapakati ndi tsinde
- ●Chisindikizo Chodalirika cha Valve Stem
- Tsinde lake ndi mawonekedwe a T odana ndi kuwomba kunja, ngakhale chipinda cha vavu chikachulukana movutikira komanso chithokomiro chosasunthika, tsinde la valve limatha kuphulika.
- Ngati tsinde itanyamula tsinde itawotchedwa, tsinde la tsinde limayikidwa pamalo pomwe paphewa ndi kukhudzana kwa thupi kuti apange mpando wotsekera.Mphamvu yosindikiza ya chisindikizo cham'mbuyo idzawonjezeka molingana ndi kuchuluka kwa kuthamanga kwapakati, kuti zitsimikizire kuti tsinde yodalirika yosindikizira pansi pa zovuta zosiyanasiyana, kuteteza kutayikira ndikupewa kufalikira kwa ngozi.
- Tsinde limatenga mawonekedwe osindikizira a mtundu wa V, kunyamula koteroko kumatha kusintha bwino kupanikizika ndi mphamvu yapakatikati ya gland kukhala mphamvu yosindikiza ya tsinde.
- Malinga ndi zomwe wogwiritsa ntchito amafuna, makina osindikizira a disc omwe amadzaza amatha kutengedwa kuti apangitse kusindikiza kwa tsinde kukhala kodalirika.
- ●Anti-static Structure
- Valve ya mpira imaperekedwa ndi anti-static structure.Pakukula kwake pansi pa DN25 ndi pamwamba pa DN25 gwiritsani ntchito mawonekedwe a anti-static masika pakati pa tsinde, thupi ndi mpira kutulutsa magetsi osasunthika popewa ngozi yamoto kapena kuphulika.
- ● Chida chotseka cha valve
- Chipangizo chotsekera ma vavu ndichofunika pamasamba ofunikira kwambiri omwe angapewere kulakwitsa kwa ma valve poteteza mapaipi.
