Ngaba iiValve zeBhola zineNdlela yokuHamba: Iintlobo, Ukufakelwa

Ngaba iiValve zeBhola zineNdlela yokuHamba? Iintlobo eziphambili kunye neMithetho yokuFakela

Ngaphambi kokuba uphendule umbuzo othiingaba ivalvu yebhola inalo na icala lokuhamba, kufuneka siqonde kuqalayintoni ivalvu yebhola, size emva koko siqonde ngcono ingxaki yecala lokuhamba kwevalvu yebhola.

Yintoni iValve yeBhola

A ivalvu yebholailawula ukuhamba kolwelo isebenzisa i-sphere engenanto, ejikelezayo enejelo lokuhamba eliphakathi. Izinto eziphambili ziquka:

- Umzimba weValve

- I-Sphere (ibhola) enomngxuma onomngxuma ocacileyo

- Isiqu sevalvu

- Indandatho yokutywina

- Isibambo/isixhobo sokuqhuba

Ukujikelezisa ibhola ngama-90° kuvula/kuvala indlela yokuhamba kwamanzi. Iivalvu zebhola zibonelela ngokutywina okugqwesileyo kunye nokusebenza ngokukhawuleza, nto leyo ezenza zibe zilungele ukusetyenziswa kwimizi-mveliso.

Ngaba iiValve zeBhola zineemfuno zeDirection yeFlow

Ngokuchasene nenkolelo ethandwayo,ezinye iivalvu zebhola zifuna indlela ethile yokuhamba, ngelixa abanye bengenzi njalo:

- Iivalvu zebhola ezibhekisa kwicala elinye(umz., ifakelwe iitruni, ihleli kamnandi): Akukho mfuneko yecala lokuhamba kwamanzi.

- Iivalvu zebhola eziyalelayo(umz.,iivalvu zebhola yesihlalo sesinyithi, Uhlobo lwe-V):Kufuneka ulandele iintolo zomzimba wevalvuukuthintela ukungasebenzi kakuhle kwetywina.

Ulwahlulo lweNdlela yokuHamba kweValve yeBhola

Iimpawu zendlela yokuhamba kwevalvu yebhola: idla ngokufakwa emzimbeni wevalvuuphawu lotolo, njengoko kubonisiwe ngezantsi

Iivalvu zeBhola ezitywiniweyo ezimacala mabini

- Iimbonakalo:Akukho zitolo zibalekayo; ufakelo olunokutshintshwa.

- Iindidi eziqhelekileyo:Iivalvu zebhola ezifakwe kwi-trunnion, iivalvu ezithambileyo, iivalvu zebhola zohlobo lwe-O.

- Izicelo:Ilungele ukusetyenziswa kwezixhobo ezixineneyo okanye ezigcwele amasuntswana.

Iivalvu zeBhola ezitywiniweyo ezingangqalanga

- Iimbonakalo:Iimpawu zotolo emzimbeni wevalvu; ukufakwa ngasemva kunokubangela umonakalo kwitywina.

- Iindidi eziqhelekileyo:Iivalvu zebhola yesihlalo sentsimbi, iivalvu zebhola zohlobo lwe-V, iivalvu ze-semi-ball ezingaqhelekanga.

- Umthetho Wokufaka:Isiphelo somzimba wevalvu encedisayoKUFUNEKA ujonge phantsi.

Izikhokelo zokuchongwa kunye nokufakwa kweNdlela yokuHamba koMzila

1. Jonga iimpawu zeValve:Iivalvu ezikhokelayo (umz., iivalvu zebhola ezidadayo ezihleli ngentsimbi) zibonisa iintolo ezicacileyo zokuhamba kwamanzi.

2. Iimpawu zoLwakhiwo:

– Iivalvu zebhola ezidadayo zihlala zibhekisa kwicala ngalinye.

– Iivalvu ezinobushushu obuphezulu/ezinoxinzelelo oluphezulu (umz., ezifakelwe kwi-trunnion) zihlala zifuna indlela yokuhamba kwamanzi.

3. Imithetho yokuQhelanisa:

–Ufakelo oluthe nkqo:Phuma ukusuka ezantsi ukuya phezulu.

–Ufakelo oluthe tye:Landela ulwalathiso lwentolo ngokungqongqo.

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

- ✅Iivalvu zebhola ezibhekisa kwicala elinye(ifakelwe i-trunnion, ihleli kakuhle):Akukho ndlela yokuhamba kwamanzikuyimfuneko.

- ⚠️Iivalvu zebhola eziyalelayo(isihlalo sesinyithi, uhlobo lwe-V):Landela iintolo zevalvuukuqinisekisa ukuvalwa kunye nokhuseleko lwemibhobho.

- ❌ Ukufakelwa kweevalvu ezijikelezayo ngendlela enye kubangelaukusilela kwesitywinakwayeiingozi zokhuseleko.
