Iyini i-Ball Valve ka-2024

I-valve yebholaiyivalvu yokulawula uketshezi, futhi isakhiwo sayo esiyisisekelo kanye nesimiso yilezi ezilandelayo:

I-valve yebholaIncazelo kanye nomgomo wokusebenza

Umzimba wevalvu yevalvu yebhola uyindilinga, unomgodi phakathi nendawo, futhi ibhola libekwe phakathi kwezihlalo zevalvu emzimbeni wevalvu. Ngokujikelezisa ibhola levalvu ngama-degree angu-90, lingavimba uketshezi olufana noketshezi noma amagesi bese livala indlela yokugeleza. Ngakho-ke, isimiso esisebenzayo sevalvu yebhola ukulawula ukuvulwa koketshezi ngokujikeleza ibhola. Ngokukhethekile, lapho isibambo noma idrayivu ijikeleza, isiqu sevalvu siqhuba ibhola ukuze lijikeleze, ngaleyo ndlela sishintshe ukuma kwesiteshi emzimbeni wevalvu futhi siqaphele ukulawula uketshezi.

I-valve yebholaIzici zesakhiwo

Izingxenye eziyinhloko zevalvu yebhola zifaka ibhola, isihlalo sevalvu, isiqu sevalvu, kanye nesibambo (noma idrayivu). Phakathi kwazo, isihlalo sevalvu ngokuvamile senziwe ngezinto ezinwebekayo ukuqinisekisa ukuthi ivalvu isebenza kahle ekuvalekeni esimweni esivaliwe. Lapho ibhola lijikeleza ukuze lithinte isihlalo sevalvu, ngenxa yokuqina kwesihlalo sevalvu, kungakhiwa uphawu lokuvimbela ukuvuza koketshezi. Ibhola lingaphenduka ngokukhululeka emzimbeni wevalvu ukulawula ukuvulwa koketshezi.

Ngaphezu kwalokho, umzimba wevalvu yevalvu yebhola unezinhlobo ezimbili: umzimba ogcwele kanye nengxenye yesiyingi. Isakhiwo esintantayo ukuthi ibhola liboshwe futhi lisekelwe yisihlalo sevalvu esifakwe emzimbeni wevalvu, esivame ukusetshenziselwa ukucindezela okuphansi kanye nobubanzi obuncane. Uhlobo lwe-trunnion lunesakhiwo esijikelezayo, ingxenye engenhla yebhola isekelwa yisiqu sevalvu, kanti ingxenye engezansi isekelwa yi-trunnion, evame ukusetshenziselwa ukucindezela okuphezulu kanye nobubanzi obukhulu.

I-valve yebholaIzinhlobo kanye nokuhlukaniswa ngezigaba

Ngokwezakhiwo ezahlukene kanye nokusetshenziswa, ama-ball valve angahlukaniswa ngezinhlobo eziningi. Isibonelo:

I-Trunnion Egibele Ibhola Valve

Ibhola liqinile futhi alinyakazi ngemva kokucindezelwa, ngokuvamile ngesihlalo sevalvu esintantayo.

I-Floating Ball Valve

Ibhola lizocindezelwa ngokuqinile ebusweni bokuvala be-outlet ngaphansi kwengcindezi ye-medium ukuqinisekisa ukuvalwa kwe-outlet.

I-valve yebhola enezindlela ezintathu

Ibhola elinesakhiwo esimise okwe-T noma okumise okwe-L lingabona ukuphambuka kanye nokuhlangana koketshezi.

I-valve yebhola eshisa kakhulu

Ibhola kanye nesihlalo sevalvu ngokuvamile kwenziwa ngezinto ezimelana nokushisa okuphezulu futhi kungasebenza ngokujwayelekile ezindaweni ezishisa kakhulu.

I-valve yebhola enomfutho ophezulu

Ibhola kanye nesihlalo sevalvu ngokuvamile kwenziwa ngezinto ezimelana nomfutho ophezulu futhi kungasebenza ngokujwayelekile ezindaweni ezinomfutho ophezulu.

Ngaphezu kwalokho, ingahlukaniswa ngokwendlela yokushayela (njengeyesandla, yomoya, kagesi, njll.), indlela yokuxhuma (njengokuxhuma kwe-flange, uxhumano olunezintambo, uxhumano lokushisela, njll.) kanye nezinto (njengezinto zensimbi, izinto ezingezona ezensimbi, njll.).

I-valve yebholaUmsebenzi kanye nokusetshenziswa

Ama-valve ebhola anezici zesakhiwo esilula, ukuvala kahle kanye nokusebenza okulula. Asetshenziswa kabanzi kuphethiloli, amakhemikhali, i-metallurgy, ugesi, amanzi ompompi, igesi yemvelo kanye neminye imboni. Angasetshenziswa ukulawula ukugeleza koketshezi nokuqinisekisa inhlanzeko nokuphepha kwendawo yokukhiqiza. Ngesikhathi esifanayo, ama-valve ebhola nawo afanelekela ukugeleza okuhlukahlukene kwe-media kanye nokugeleza kwe-gas-solid kanye ne-liquid-solid kwezigaba ezimbili, futhi anamathemba amakhulu entuthuko.

Ukunakekelwa nokunakekelwa

Ukuze kuqinisekiswe ukuthi ivalvu yebhola ingasebenza kahle isikhathi eside, kudingeka ukulungiswa nokunakekelwa okuvamile. Izinyathelo ezithile zifaka:

1. Hlola njalo umzimba wevalvu kanye nesiqu sevalvu ukuze ubone izimpawu zokugqwala, imifantu noma omunye umonakalo.

2. Hlola ukusebenza kokuvala kwevalvu ukuqinisekisa ukuthi akukho ukuvuza.

3. Kuma-valve ebhola asetshenziswa ngesandla, gcoba njalo isiqu se-valve kanye ne-gearbox ukuze unciphise ukuguguleka.

4. Gcina ingaphandle levalvu yebhola lihlanzekile futhi ususe uthuli namafutha; uma kungenzeka, hlanza ibhola levalvu kanye nesihlalo sevalvu njalo ukuze uvimbele ukungcola ukuthi kunganqwabelani.

5. Hlola ukuthi zonke izikhonkwane (ezifana nezikulufo namantongomane) zikhululekile yini bese uziqinisa ngesikhathi.

Ngokufigqiwe

I-valve yebhola iwuhlobo lwe-valve olusebenza kahle noluthembekile oludlala indima ebalulekile emikhakheni eyahlukahlukene yezimboni. Ngokufaka, ukusebenzisa kanye nokulungisa ngendlela efanele, ukusebenza okuzinzile kwe-valve yebhola kungaqinisekiswa futhi isikhathi sayo sokusebenza singandiswa.
