Ungafinyelela kanjani ukuvulwa okusheshayo nokuvala ama-valve ebhola?

Ukuvulwa nokuvala ngokushesha kweama-valve ebholaincike kakhulu ekwakhiweni kwesakhiwo esizungezayo kanye nendlela yokuvala uphawu lokungqubuzana okuphansi. Umgomo othize umi kanje:

1. 90 ° ukuzungezisa ukuvula nokuvala

I-valve core ye-i-valve yebholaiyindilinga futhi inembobo ngaphakathi. Lapho isibambo noma idivayisi yokushayela ishayela ibhola ukuze lizungezise ngo-90 °, imbobo edlulayo kanye neshaneli yomzimba yevalvu iyashintsha isuka eqondaniswe ngokuphelele (evuleke) iye e-perpendicular (evaliwe), noma isebenze kwelinye icala. Lo mklamo uvumela isenzo sokuvula nokuvala ukuthi siqedwe ngekota nje yokujika, ngokushesha kakhulu kunamavalvu afana namavalvu esango nama-globe valves adinga ukuphenduka okuningi kokujikeleza.

2. Idizayini yetorque ephansi

I-Streamlined Sphere: Ingaphezulu lendilinga libushelelezi, linokumelana okuphansi lapho uketshezi ludlula. Uma ivulwa, ingcindezi ephakathi nendawo ingasiza ekuphusheni i-sphere, yehlise itorque yokusebenza.

Isakhiwo sebhola elintantayo noma elingashintshi:

I-valve yebhola entantayo: Ibhola lintanta lezansi nomfula libheke endaweni evalekayo ngaphansi kwengcindezi yendawo ephakathi nendawo, lenze i-self seal, futhi amandla asebenzayo adinga kuphela ukunqoba ukungqubuzana kweringi yokuvala.

Kulungisiwei-valve yebhola: Ibhola lilungiswa ngeziqu ze-valve ezingaphezulu neziphansi futhi ifanele izimo zokucindezela okuphezulu. Inciphisa ukungqubuzana okujikelezayo ngama-bearings kuyilapho igcina izici eziphansi ze-torque.

3. Ukwenziwa ngcono kwesakhiwo sokubeka uphawu

I-Elastic sealing ring: njenge-PTFE (i-polytetrafluoroethylene) noma indandatho yensimbi yokuvala, ibambelela ngokuqinile kwindilinga ngaphansi kwe-pre tension, kodwa ine-coefficient ephansi yokungqubuzana kanye nokumelana okuphansi ngesikhathi sokuzungezisa.

Ukuvalwa kwe-Bidirectional: Amanye ama-valve ebhola aklanywe ngokuvaleka kwe-bidirectional, okunganqamula uketshezi ngokushesha kungakhathaliseki ukuthi ukugeleza kwe-medium, ngaphandle kwesidingo sokulungisa isiqondiso sokusebenza.

4. Ithuluzi lokushayela elisizayo

Ukusebenza mathupha: Isibambo esifushane noma idizayini yelever ingakhulisa amandla okusebenza futhi izuze ukuzungezisa ngokushesha.

I-actuator kagesi/i-pneumatic: Ishayelwa injini noma isilinda, ingaqeda ukuvulwa nokuvala kungakapheli imizuzwana engu-0.5-5 futhi ifanele izinhlelo zokulawula ezishintshayo.

Izimo zohlelo lokusebenza ezijwayelekile

Ukuvalwa kwezimo eziphuthumayo: njengamasistimu okuvikela umlilo namapayipi egesi, adinga ukuvalwa phakathi nemizuzwana embalwa ukuze kunqandwe ingozi ekunyukeni.

Ukulawulwa kwefrikhwensi ephezulu: Ukulawulwa kokugeleza ezinkambisweni zamakhemikhali, kuyadingeka ukushintsha ngokushesha ukuvuleka ukuze kugcinwe imingcele yenqubo ezinzile.

Isifinyezo: Amavalvu ebhola azuze isivinini sokuvula nokuvala esidlula kude leso samanye ama-valve ngokuzungezisa okungu-90 °, idizayini yetorque ephansi, ukwenziwa kahle kwezinsimbi, nosizo lokushayela idivayisi, okuwenza abe yinketho ekhethwayo yezimo zokuphendula ngokushesha.
