Uyini umehluko phakathi kwevalvu yokuhlola nevalvu yokusiza

Kukhona umehluko omkhulu phakathiama-valve okuhlolakanye nama-valve okusiza ezicini eziningi, okubonakala kakhulu emsebenzini wawo, isakhiwo, isimiso sokusebenza kanye nezimo zokusetshenziswa. Nasi isixazululo:

Umehluko wokusebenza

I-valve yokuhlola: Umsebenzi oyinhloko ukuvimbela i-media ukuthi ibuyele emuva epayipini. Ivumela i-media ukuthi igeleze ngokukhululeka ohlangothini olulodwa, kodwa lapho i-media igeleza ibuyela emuva, i-check valve izovala ngokuzenzakalelayo ukuvimbela i-media backflow ukuthi ingabangela umonakalo ohlelweni. I-check valve nayo idlala indima ebalulekile ekuvimbeleni iphampu kanye ne-drive motor yayo ukuthi ibuyele emuva futhi ivimbele i-media esitsheni ukuthi ivuza.

I-valve yokusiza: Umsebenzi oyinhloko ukuvimbela ingcindezi ohlelweni noma emishinini ukuthi idlule inani elibekiwe. Lapho ingcindezi idlula inani elibekiwe, ivalvu yokuphepha izovuleka ngokuzenzakalelayo futhi ikhulule ingxenye yendlela ukuze inciphise ingcindezi, ngaleyo ndlela ivikele ukuphepha kwemishini nohlelo. Ivalvu yokuphepha iyithuluzi elibalulekile lokuvikela imishini nabasebenzi ekucindezelweni okukhulu.

Umehluko wesakhiwo

I-valve yokuhlola:Isakhiwo silula kakhulu, ngokuvamile ngomzimba, isembozo se-valve, isiphethu se-valve nesihlalo kanye nezinye izingxenye. Isimiso saso sokusebenza sincike kakhulu emandleni akhiqizwa ukugeleza kwe-medium ukuvula nokuvala i-valve.

Ivalvu yokuphepha:Isakhiwo siyinkimbinkimbi kakhulu, ngokuvamile ngomzimba wevalvu, isiphethu, izingcezu ze-shrapnel, izingxenye zomhlahlandlela kanye nezinye izingxenye. Lezi zingxenye zisebenza ndawonye ukuqinisekisa ukuthi ivalvu yokuphepha iyavuleka futhi ivale ngokunembile lapho kufinyelelwa ingcindezi ebekiwe. Ukwakheka kwesakhiwo sevalvu yokuphepha kudinga ukucabangela ingcindezi, izinga lokushisa, ukugeleza kanye nezinye izici ze-medium.

Umehluko kumgomo wokusebenza

I-valve yokuhlola: Umgomo wokusebenza usekelwe emandleni akhiqizwa ukugeleza kwe-medium. Lapho i-medium igeleza phambili epayipini, amandla akhiqizwa yi-medium asunduza idiski ye-check valve ivuleke futhi avumele i-medium ukuthi idlule. Lapho i-medium igeleza ngokubuyela emuva, idiski ye-valve izobhekana nesenzo esihlangene se-medium kanye nentwasahlobo ye-valve ukuvala i-valve, ngaleyo ndlela ivimbele i-medium ukuthi igeleze emuva.

I-valve yokuphepha: Umgomo wokusebenza usekelwe ekulawuleni ingcindezi. Lapho ingcindezi ohlelweni noma emishinini idlula inani elibekiwe, intwasahlobo yevalvu yokuphepha iyacindezelwa ngezinga elithile, futhi ivalvu izovuleka futhi ikhulule ingxenye yendlela yokunciphisa ingcindezi. Lapho ingcindezi yehla ngaphansi kwenani elibekiwe, intwasahlobo ibuyela endaweni yayo bese ivala ivalvu.

Umehluko phakathi kwezimo zohlelo lokusebenza

I-valve yokuhlola: isetshenziswa kabanzi emikhakheni yamakhemikhali, kaphethiloli kanye neminye imikhakha yezimboni yesistimu yamapayipi. Isetshenziswa kakhulu ukuvimbela umonakalo ohlelweni olubangelwa ukubuyela emuva kwe-media, njengokuvimbela iphampu kanye ne-drive motor yayo ukuthi ibuyele emuva, ukuvimbela i-media esitsheni ukuthi ingavuzi.

I-valve yokuphepha: isetshenziswa kabanzi ezimbonini zamakhemikhali, zikagesi, uphethiloli, i-metallurgy kanye neminye imboni yemishini noma izikhungo. Ikakhulukazi kuma-boiler, imikhumbi yokucindezela, amapayipi kanye nezinye izinhlelo, ama-valve okuphepha ayizinto ezibalulekile zokuvikela ukuvimbela imishini ukuthi ingonakali ngenxa yokucindezela okuphezulu.

Ngokufigqiwe

Kukhona umehluko omkhulu phakathiama-valve okuhlolakanye nama-valve okuphepha maqondana nomsebenzi, isakhiwo, isimiso sokusebenza kanye nezimo zokusetshenziswa. Ekusetshenzisweni okungokoqobo, izinhlobo zama-valve ezifanele kudingeka zikhethwe ngokwezidingo ezithile kanye nezimo ukuqinisekisa ukusebenza okuvamile nokuphepha kwemishini nezinhlelo.
