Ukuhlaziywa Kobuhle Nokubi Kwezinhlobo Ezinhlanu Ezivamile Zamavaluvu 2

3. I-Ball Valve

I-valve yebhola yavela ku-valve yepulaki. Ingxenye yayo yokuvula neyokuvala iyindilinga, futhi imbulunga izungeza ngo-90° izungeze i-axis yesiqu se-valve ukufeza injongo yokuvula nokuvala. I-valve yebhola isetshenziswa kakhulu kumapayipi ukusika, ukusabalalisa, nokushintsha indlela yokuhamba kwento ephakathi. I-valve yebhola eklanywe ngokuvula okumise okwe-V nayo inomsebenzi omuhle wokulawula ukugeleza.

Imboni ye-valve ye-TWS inikezela ngevalve yevavemvane ehlezi ecwecwe ehlala njalo engu-YD37A1X3-16Q, ivalve uvemvane olunezinhlangothi ezimbiliI-D34B1X3-16Q, I-valve ye-butterfly ene-eccentric ephindwe kabili ngokusho kwe-Ser.13 noma uchungechunge 14, BS5163/F4/F5 / ANSI CL150 i-rubber ehlezi i-valve yesango, i-Y-strainer, i-valve yokulinganisa, i-back flow preventer.

3.1 Izinzuzo:

① Inokumelana nokugeleza okuphansi kakhulu (cishe 0).

② Njengoba ingeke ibambeke ngesikhathi sokusebenza (uma ingekho okokugcoba), ingasetshenziswa ngendlela enokwethenjelwa kumithombo yezindaba ebolayo kanye noketshezi olunamaphuzu amancane abilayo.

③ Ingafinyelela ukubekwa uphawu okuphelele ngaphakathi kwengcindezi enkulu kanye nebanga lokushisa.

④ Ingakwazi ukuvula nokuvala ngokushesha. Isikhathi sokuvula nokuvala kwezinye izakhiwo yimizuzwana engu-0.05 kuya ku-0.1 kuphela, siqinisekisa ukuthi singasetshenziswa ezinhlelweni ezizenzakalelayo zamabhentshi okuhlola. Lapho uvula futhi uvala i-valve ngokushesha, awukho umthelela ngesikhathi sokusebenza.

⑤ Ingxenye yokuvala eyindilinga ingama ngokuzenzakalelayo endaweni yomngcele.

⑥-- Isisetshenziswa esisebenzayo sivalwe ngokuthembekile kuvalvu.

Q⑦ Uma i-valve ivuleke ngokugcwele futhi ivaleke ngokugcwele, izindawo zokuvala zendilinga kanye nesihlalo sevalvu ziyahlukaniswa ukusuka kokuphakathi. Ngakho-ke, okuphakathi okugeleza ku-valve ngesivinini esikhulu ngeke kubangele ukuguguleka kwezindawo zokuvala.

⑧ Inesakhiwo esihlangene nesisindo esincane. Kungabhekwa njengesakhiwo se-valve esinengqondo kakhulu sezinhlelo ezisezingeni eliphansi lokushisa eliphakathi.

⑨ Ii-valveumzimba u-symmetrical. Ikakhulukazi ngesakhiwo somzimba we-valve eshiselwe, ingakwazi ukumelana nokucindezeleka okuvela epayipini.

⑩ Ingxenye yokuvala ingakwazi ukumelana nomehluko wengcindezi ephezulu ngesikhathi sokuvala.

⑪ Ivalve yebhola enomzimba wevalve oshiselwe ngokugcwele ingangcwatshwa ngokuqondile ngaphansi komhlaba, ivikele izingxenye zangaphakathi zevalvu ekugqwaleni. Impilo yayo ephezulu yesevisi ingafinyelela eminyakeni engama-30, okuyenza ibe ivalvu ekahle kakhulu yamapayipi kawoyela negesi yemvelo.

3.2 Okubi:

① Okuyinhlokoi-valveimpahla yokuvala isihlalo se-valve yebhola yi-polytetrafluoroethylene (PTFE). Ayisebenzi cishe kuzo zonke izinto zamakhemikhali futhi inezici eziphelele njenge-coefficient encane yokungqubuzana, ukusebenza okuzinzile, ukumelana nokuguga, ibanga elibanzi lokushisa elisebenzayo, nokusebenza okuhle kakhulu kokuvala. Kodwa-ke, izici ezibonakalayo ze-PTFE, okuhlanganisa i-coefficient ephezulu uma kuqhathaniswa yokunwetshwa, ukuzwela ekugelezeni okubandayo, kanye nokungahambi kahle kwe-thermal, kudinga ukuthi ukwakheka kwesivalo sesihlalo se-valve kumele kwenziwe eduze kwalezi zakhiwo. Ngakho-ke, lapho impahla yokuvala iqina, ukwethembeka kophawu kuyaphazamiseka. Ngaphezu kwalokho, izinga lokushisa lokumelana ne-PTFE liphansi kakhulu, futhi lingasetshenziswa kuphela emazingeni okushisa angaphansi kuka-180°C. Uma izinga lokushisa lidlula leli nani, into yokuvala izoguga. Uma kucatshangelwa ukusetshenziswa isikhathi eside, ngokuvamile isetshenziswa kuphela ku-120°C.

② Ukusebenza kwayo kokulawula kubi ngandlela thile kunaleyo yevalvu yomhlaba, ikakhulukazi kumavalvu womoya (noma amavalvu kagesi.

5. I-Plug Valve

I-valve yepulaki ibhekisela ku-valve ejikelezayo lapho ingxenye yokuvala isesimweni se-plunger. Ngokuzungezisa i-90 °, ukuvuleka kwephaseji kupulaki kwenziwa ukuxhumana noma ukuhlukaniswa nokuvulwa kwephaseji emzimbeni we-valve, ukufeza ukuvuleka noma ukuvala i-valve. Ibizwa nangokuthi iqhude, i-stopcock, noma isango elijikelezayo. Ukuma kwepulaki kungaba yi-cylindrical noma i-conical. Kunezinhlobo eziningi zayo, okuhlanganisa uhlobo oluqondile, uhlobo lwezindlela ezintathu, kanye nohlobo lwezindlela ezine. Isimiso saso ngokuyisisekelo sifana nesovali yebhola.

5.1 Izinzuzo:

① Ilungele ukusebenza kaningi, ngokuvula nokuvala okusheshayo nokulula.

② Ukumelana noketshezi kuncane.

③ Inesakhiwo esilula, ivolumu encane, isisindo esincane, futhi kulula ukuyinakekela.

④ Inokusebenza okuhle kokuvala.

⑤ Ayivinjelwe isiqondiso sokufaka, isiqondiso sokugeleza se-medium singaba ngokunganaki.

⑥ Akukho ukudlidliza, futhi umsindo uphansi.

5.2 Okubi:

⑦ Indawo yokuvala inkulu kakhulu, okubangela itorque eningi kanye nokungaguquguquki okwanele.

⑧ Ithonywe isisindo sayo, ubukhulu bobubanzi be-valve bukhawulelwe.

Ekusetshenzisweni kwangempela, uma i-valve yosayizi omkhulu idingeka, isakhiwo sepulaki esibuyela emuva kufanele sisetshenziswe, okungenzeka sithinte umphumela wokuvala.
