Ivalvu yokujonga ibhonethi etywiniweyo yoMzi-mveliso ekumgangatho ophezulu Umthengisi wefektri waseTshayina Umvelisi
Yintoni ivalvu yokujonga ibhonethi etywiniweyo?
Iivalvu zokujonga, iivalvu ezingabuyisiyo, zenzelwe ukuthintela ukuguquka kokuhamba kwamanzi kwinkqubo yemibhobho. Ezi valve zivulwa zizinto ezihambayo kwipayipi.Uxinzelelo lolwelo oludlula kwinkqubo luvula ivalvu, ngelixa naluphi na uguquko lokuhamba kwamanzi luya kuyivala ivalvu.Ukuvalwa kwenziwa bubunzima bendlela yokujonga, ngoxinzelelo lomqolo, ngesipringi, okanye ngokudibanisa ezi ndlela.
ivalvu yokujonga ibhonethi etywiniweyo, ivalvu yokujonga iswing eyilwe kwaye yenziwe ngokwe-ASME B16.34, vavanya kwaye bahlole i-API598, i-API6D.
Loo mngxuma kufuneka ucace ukuze nantoni na idlule. Idiski inamathele kwihinji, ukuze idiski ivuleke okanye ivalwe xa ulwelo lufika kwidiski. Ifana nocango olujikelezayo. Indlela ehamba ngayo yeyona nto ibalulekileyo xa usebenzisa ezi valve.
Njengoko bekutshiwo ngaphambili, ivalvu yokujonga ukujika yenzelwe xa ufuna ulwelo oluhamba kwicala elinye kuphela. Enye into ebalulekileyo ngezi valve kukuba azidingi mandla angaphandle, nto leyo eyenza ukuba zilungele ukusetyenziswa ngeendlela ezahlukeneyo. Zikwavumela ulwelo ukuba ludlule ngaphandle kokucothisa ukuhamba kwamanzi xa luvuliwe ngokupheleleyo.Iivalvu zokujonga i-swing zihlala zifakelwa kunye neevalvu zesango kuba zibonelela ngokuhamba kwamanzi ngokukhululekileyo.Ziyacetyiswa kwimigca enesantya esiphantsi kwaye akufuneki zisetyenziswe kwimigca enesantya esiphantsi xa ukubetheka okanye ukugquma okuqhubekayo kuya kutshabalalisa izinto zokuhlala.Le meko ingalungiswa ngokuyinxenye ngokusebenzisa i-lever yangaphandle kunye nobunzima.
Iimpawu eziphambili zevalvu yokujonga ibhonethi etywiniweyo
Iimpawu eziphambili zeivalvu yokujonga ibhonethi etywiniweyo:
- ● Umzimba kunye nesigqubuthelo: Ii-castings ezenziwe ngomatshini ngokuchanekileyo. Isiqu asingeni emzimbeni.
- ● Idiski: Yakhiwe ngendlela eqinileyo ukuze imelane nokuphazamiseka okukhulu kwenkonzo yevalvu yokujonga. Iqinile nge-13Cr, i-CoCr alloy, i-SS 316, okanye i-Monel, yaza yagxunyekwa yaya kugqitywa ngesipili. Idiski ye-SS 316 ejongene ne-CoCr alloy nayo iyafumaneka.
- ● Indibano yeDiski: Idiski engajikeleziyo ibotshelelwe ngokukhuselekileyo kwi-disc hanger nge-lock nut kunye ne-cotter pin. I-disc hanger ixhaswa kwi-hinge pin eqinileyo ye-disc carrier eneempawu ezintle zokuthwala. Zonke iindawo zifikeleleka ukusuka phezulu ukuze kube lula ukuzilungisa.
