1. Isimiso:
I-Ball Valve: Ingxenye yokuvula neyokuvala ye-valve yebhola iyindilinga, futhi inhloso yokuvula nokuvala ibonakala ngokuzungezisa indilinga engu-90° izungeze i-eksisi yesiqu se-valve.I-valve yebhola isetshenziselwa kakhulu ukusika, ukusabalalisa kanye nokushintsha indlela yokuhamba kwe-medium epayipini.I-valve yebhola eklanywe ngokuvuleka okumise okwe-V nayo inomsebenzi omuhle wokulungisa ukugeleza.
Ivaluvu Yesango: Ilungu elivalayo (I-Wedge) lihamba ligudle isiqondiso esime mpo se-eksisi yesiteshi isetshenziswa ngokuyinhloko ukunqamula okuphakathi epayipini, okungukuthi, elivuleke ngokugcwele noma elivalwe ngokugcwele.Ngokuvamile, ama-valve esango awakwazi ukusetshenziselwa ukulawula ukugeleza.Ingasetshenziswa ekucindezelweni kokushisa okuphansi noma ukushisa okuphezulu nokucindezela okukhulu, futhi ingasetshenziswa ngokusho kwezinto ezahlukene ze-valve.
2. Izinzuzo kanye Nokubi
2.1 Izinzuzo ze-valve yebhola
I-1) Inokumelana nokugeleza okuphansi (empeleni i-0);ingasetshenziswa ngendlela ethembekile emithonjeni ebolayo kanye noketshezi lwamaphuzu aphansi abilayo ngoba ngeke ibambeke ngesikhathi sokusebenza (uma ingekho into yokuthambisa);
2) , endaweni enkulu yokucindezela kanye nezinga lokushisa, ingafinyelela ukubekwa uphawu okuphelele;
I-3) Ingabona ukuvulwa nokuvala ngokushesha, futhi isikhathi sokuvula nokuvala kwezinye izakhiwo yi-0.05 ~ 0.1s kuphela ukuqinisekisa ukuthi ingasetshenziswa ohlelweni oluzenzakalelayo lwebhentshi lokuhlola.Lapho i-valve ivuliwe futhi ivaliwe ngokushesha, ukusebenza akunawo umthelela;
4) .Ukuvalwa okuyindilinga kungamiswa ngokuzenzakalelayo endaweni yomngcele
5) .Uma ivuliwe ngokugcwele futhi ivalwe ngokugcwele, indawo yokuvala yebhola kanye nesihlalo se-valve ihlukaniswe phakathi nendawo, ngakho-ke okuphakathi okudlula ku-valve ngesivinini esikhulu ngeke kubangele ukuguguleka kwendawo yokuvala;
6) .Ngesakhiwo esihlangene nesisindo esilula, singabhekwa njengesakhiwo se-valve esinengqondo kakhulu sohlelo oluphakathi lokushisa oluphansi;
7) Umzimba we-valve unokulinganisa, ikakhulukazi isakhiwo somzimba we-valve eshiselwe, engakwazi ukumelana nokucindezeleka kwepayipi;
I-8) Ingxenye yokuvala ingamelana nomehluko wengcindezi ephezulu lapho ivala.
9).I-valve yebhola enomzimba we-valve oshiselwe ngokugcwele ingangcwatshwa ngokuqondile emhlabathini, ukuze ama-valve angaphakathi angagqwali, futhi impilo yesevisi ingafinyelela iminyaka engu-30.Kuyi-valve efanelekile yamapayipi kawoyela negesi yemvelo.
2.2 Ukungalungi kwe-valve yebhola
Ngenxa yokuthi into ebaluleke kakhulu yokuvala isihlalo se-valve yebhola i-polytetrafluoroethylene, ayisebenzi cishe kuzo zonke izinto zamakhemikhali, futhi inezici ze-coefficient encane yokungqubuzana, ukusebenza okuzinzile, akulula ukuguga, ububanzi obubanzi bokushisa nokusebenza okuhle kakhulu kokuvala.Izici eziphelele.
Kodwa izici ezibonakalayo ze-PTFE, okuhlanganisa i-coefficient ephezulu yokunwetshwa, ukuzwela ekugelezeni okubandayo, nokungahambi kahle kwe-thermal, kudinga ukuthi imiklamo yophawu lwesihlalo kumele yakhiwe eduze kwalezi zakhiwo.Ngakho-ke, lapho izinto zokuvala ziba nzima, ukuthembeka kokubeka uphawu konakalisiwe.
Ngaphezu kwalokho, i-PTFE inebanga eliphansi lokumelana nezinga lokushisa futhi ingasetshenziswa kuphela ngaphansi kuka-180 °C.Ngaphezu kwalokhu kushisa, izinto zokuvala zizokwehlisa izinga.Endabeni yokusetshenziswa isikhathi eside, ngokuvamile isetshenziswa kuphela ku-120 °C.
2.3 Izinzuzo zevalvu yesango
I-1) Ukumelana nokugeleza kuncane.Isiteshi esiphakathi ngaphakathi komzimba we-valve siqondile, i-medium igeleza ngendlela eqondile, futhi ukumelana nokugeleza kuncane.
2) Konga kakhulu abasebenzi uma uvula noma uvala.Uma kuqhathaniswa ne-valve yembulunga, ngoba kungakhathaliseki ukuthi ivuliwe noma ivaliwe, isiqondiso sokuhamba kwesango sibhekene nesiqondiso sokugeleza kwe-medium.
3) Ukuphakama kukhulu futhi isikhathi sokuvula nokuvala side.Ukuvula nokuvalwa kwesango kukhulu, futhi ukuphakamisa nokwehlisa kwenziwa ngesikulufu.
I-4) Isimo sesando samanzi akulula ukwenzeka.Isizathu yisikhathi eside sokuvala.
5) I-medium ingageleza kunoma iyiphi indlela nhlangothi zombili, okulula ukuyifaka.Ishaneli ye-valve yesango i-symmetrical nhlangothi zombili.
2.4 Ukungalungi kwevalvu yesango
I-1) Kulula ukubangela ukuguguleka nokuklwebheka phakathi kwezindawo zokuvala, futhi ukunakekela kunzima kakhulu.
I-3) Ubukhulu bangaphandle bukhulu, isikhala esithile siyadingeka ukuvula, futhi isikhathi sokuvula nokuvala side.
4) Isakhiwo siyinkimbinkimbi kakhulu.
Ingabe ama-valve ebhola angcono kunama-valve esango?
Ubuhle bamavalvu ebhola ngaphezu kwamavalvu esango ukuthi avale aqine, ngakho amelana kakhulu nokuvuza kunamavalvu esango.Lokhu kungenxa yesici sabo sesaphulelo esingu-100%.Ngaphezu kwalokho, ama-valve ebhola kulula ukuwasebenzisa kunama-valve esango, anezinga eliphansi lokuhluleka, futhi ahlala isikhathi eside.
Izici zamavalvu ebhola ziwenza alungele ukuvala uketshezi lokulawula.
Amavalvu ebhola ahlala esebenza kahle ngemva kwemijikelezo eminingi futhi anokwethenjelwa futhi akwazi ukuvala ngokuphepha ngisho nangemva kwesikhathi eside sokungasebenzi.Ngenxa yalezi zizathu, ama-valve ebhola ngokuvamile akhethwa ngaphezu kwama-valve esango kanye nama-globe.
Kodwa ngaphansi kwengcindezi efanayo nosayizi, i-valve yebhola ibiza kakhulu kune-valve yesango.
