IiValve zeBhalbhu zePort eziGqibeleleyo kunye neziNciphisiweyo: Umahluko oPhambili kunye neSikhokelo soKhetho
Iivalvu zebhola zizinto ezibalulekileyo kwiinkqubo zolawulo lolwelo, zahlulwe zibe ziintlobo ezimbini eziphambili: i-full port (i-full bore) kunye ne-reduced port (i-reduced bore). Ukuqonda umahluko wazo kuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle kweendleko kwizicelo zoshishino.
Ukuchaza iiValve zeBhalbhu zePort epheleleyo kunye neReduced Port Ball Valves
-I-Valve yeBhola yePort epheleleyo: Ububanzi bangaphakathi bevalvu bufana ne-≥95% yobubanzi obuqhelekileyo bombhobho (umz., ivalvu ye-2-intshi inendlela yokuhamba kwe-50mm).
Iingcebiso: Xa ukhetha ivalvu yebhola, ivalvu yebhola ye-2 Inch egcweleyo inobungakanani bevalvu obubhalwe njenge-NPS 2.
- Ivalvu yeBhala yePort encitshisiweyo: Ububanzi bangaphakathi buyi-≤85% yobubanzi obuqhelekileyo bombhobho (umz., ivalvu ye-2-intshi inendlela yokuhamba kwamanzi eyi-~38mm).
Icebiso: Xa ukhetha ivalvu yebhola, ivalvu yebhola ye-2 Inch ebotshelelwe kancinci inobungakanani bevalvu obubhalwe njenge-NPS 2 x 1-1/2.
Umahluko oPhambili kwiSakhiwo
| Uphawu | Ivalve yeBhola epheleleyo | Ivalvu yeBhola eNcitshisiweyo |
|---|---|---|
| Uyilo lweNdlela yokuHamba | Ilingana nobubanzi bombhobho; akukho kuncitshiswa | Ubungakanani obu-1-2 obuncinci kunepayipi |
| Ukusebenza kakuhle kokuhamba kwamanzi | Akukho mingcelelo yokuhamba kwamanzi; ukwehla okuncinci koxinzelelo | Ukumelana okuphezulu kune-full bore |
| Ubungakanani beevalvu (i-NPS) | Umbhobho ohambelanayo (umz., i-NPS 2) | Ibonisa ukunciphisa (umz., i-NPS 2 × 1½) |
| Ubunzima kunye nokuxinana | Ulwakhiwo olunzima; oluqinileyo | Ilula nge-30%; uyilo lokonga indawo |
Uthelekiso lokusebenza kunye nesicelo
| I-Factor | Ivalve yeBhola epheleleyo | Ivalvu yeBhola eNcitshisiweyo |
|---|---|---|
| Imidiya efanelekileyo | Ulwelo oluthambileyo (ioyile ekrwada, uthuli), iinkqubo zokugaya iihagu | Iigesi, amanzi, ulwelo olune-viscosity ephantsi |
| Iimfuneko zoMsinga | Ukuhamba okuphezulu okunokumelana okuncinci | Ukuhamba okulawulwayo; amandla ahlengahlengiswayo |
| Amatyala aqhelekileyo okusetyenziswa | Iipayipi eziphambili (ioyile/igesi), iinkqubo zokucoca | Imigca yamasebe, iiprojekthi ezijongana nohlahlo-lwabiwo mali |
| Ukwehla koxinzelelo | Ukumelana phantse akukho mfuneko; ilungele imibhobho emide | Ukwehla koxinzelelo lwengingqi okuphezulu |
| Ukusebenza kakuhle kweendleko | Ixabiso eliphezulu kwangaphambili | Ixabiso eliphantsi ngama-30%; umthwalo wepayipi oncitshisiweyo |
Indlela yokukhetha iValve yeBhola echanekileyo
Beka phambili i-Full Bore Ukuba:
1. Ukuphatha i-viscous/slurry media okanye kufuna ukuxutywa.
2. Inkqubo ifuna ukuhamba okuphezulu kunye nokulahlekelwa koxinzelelo okuncinci.
3. Ukucoca/ukulungisa imibhobho yinto eqhelekileyo.
Khetha i-Reduced Bore Xa:
1. Ukusebenza ngeegesi okanye ulwelo olune-viscosity ephantsi.
2. Kukho imida yohlahlo lwabiwo-mali; iivalvu ezikhaphukhaphu ziyathandwa.
3. Ulawulo lokuhamba kwamanzi kunye nokwenza ngcono indawo kubaluleke kakhulu.
Isizathu Sokuba Kubalulekile
1. IiValve zeFull Bore zisusa imida yokuhamba kwamanzi, zinciphisa iindleko zamandla kuthutho olude.
2. IiValvu zeBore eziNciphisiweyo zibonelela ngokonga iindleko (ukuya kuthi ga kwi-1/3 yexabiso eliphantsi) kunye nolawulo lokuhamba kwamanzi olusebenzayo kwiinkqubo ezincinci, ngelixa zinciphisa umthwalo wolwakhiwo kwimibhobho.
