Valavu yapamwamba kwambiri yapadziko lonse lapansi yamakampani yotsika kwambiri China fakitale yogulitsa Wopanga
Kodi valavu yozungulira ndi chiyani pa kuthamanga kwa magazi?
API602valavu yapadziko lonse lapansi yogwiritsira ntchito kuthamanga kwambirindi kapangidwe kapadera ka ma valve ang'onoang'ono padziko lonse lapansi.
Monga valavu ya globe, ili ndi mawonekedwe onse a valavu ya globe, imatsegula ndi kutseka mwachangu.
Ma valve. Monga mwachizolowezi, magawo otsegulira ndi otseka ndi chipata, okhala ngati wedge, ndichifukwa chake amatchedwa valavu ya chipata cha wedge. Njira yoyendetsera chipata ndi yolunjika ku mbali yamadzi. Vavu ya chipata cha wedge imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu ndipo singasinthidwe ndikukokedwa. Vavu ya chipata idapangidwa kuti igwiritsidwe ntchito yotseguka kwathunthu kapena yotsekedwa kwathunthu, chifukwa chifukwa cha mawonekedwe a zotchingira zake zomwe zili ndi mawonekedwe a wedge, ngati itagwiritsidwa ntchito pang'ono, padzakhala kutayika kwakukulu kwa kuthamanga ndipo pamwamba potseka padzawonongeka madzi akakhudzidwa.
Zinthu zazikulu za valavu yozungulira ya kuthamanga kwambiri?
Zinthu zazikulu za API602valavu yapadziko lonse lapansi yogwiritsira ntchito kuthamanga kwambiri
- 1) Tsinde lokwera ndi ulusi wolondola wa acme wowirikiza kuti ligwire ntchito mwachangu.
- 2) Cholumikizira cha thupi kuchokera ku bonnet chomwe chimapangidwa kuti chigwiritse ntchito katundu wofanana pa gasket kuti chitsimikizire kuti palibe kutayikira kwa madzi.
- 5) Chipinda chakumbuyo chomwe chimapangidwa kuti chichepetse kupsinjika kwa kumbuyo kwa chivundikiro cha tsinde chikakhala pansi mokwanira. Sikoyenera kusintha chivundikiro cha tsinde pansi pa kupsinjika.
- 6) Kuyika tsinde la tsinde lapangidwa kuti liwongolere bwino kutulutsa kwa mpweya wotuluka mumlengalenga. Kuchuluka kwa kutuluka kwa mpweya wotuluka kumatsimikizika ndi kutha bwino kwa malo otsekera tsinde, kutsika kwa ma diametrical clearances komanso kuwongolera kulunjika kwa tsinde.
- 7) Chisindikizo cha Bellows chikupezeka ngati mupempha

Chiwonetsero cha Zamalonda: valavu ya globe ya kuthamanga kwambiri
Kugwiritsa ntchito valavu yozungulira pa kuthamanga kwambiri
Valavu yozungulira ya kuthamanga kwambiri imagwiritsidwa ntchito kwambiri m'mapaipi okhala ndi madzi ndi madzi ena. Petroli, mafuta, mankhwala, mafuta, mphamvu ndi mautumiki ndi zina zotero, makamaka m'malo omwe kuyenda bwino kwa madzi kumafunikira, kutsekedwa bwino komanso ntchito yayitali. Kusankha kwakukulu kwa zinthu zopangira chipolopolo ndi zokongoletsa kumaphimba ntchito zosiyanasiyana, kuyambira ntchito ya tsiku ndi tsiku yosawononga mpaka ntchito yofunika kwambiri yokhala ndi zinthu zowononga kwambiri.
