A i-valveiyithuluzi lokulawula ulayini owuketshezi. Umsebenzi wayo oyisisekelo uwukuxhuma noma ukunqamula ukujikeleza kwendandatho yepayipi, ukushintsha isiqondiso sokugeleza kwe-medium, ukulungisa ukucindezela nokugeleza kwe-medium, nokuvikela ukusebenza okuvamile kwepayipi kanye nemishini.
一.Ukuhlukaniswa kwama-valve
Ngokusebenzisa kanye nomsebenzi zingahlukaniswa zibe:
1. I-valve yokuvala: nqamula noma uxhume ipayipi lepayipi. Okufana nalokhu: i-valve yesango, i-globe valve, i-valve yebhola, i-butterfly valve, i-diaphragm valve, i-plug valve.
2. Hlola i-valve: vimbela okuphakathi nendawo epayipini ukuthi ligeleze lihlehle.
3. I-valve yokusabalalisa: shintsha isiqondiso sokugeleza kwe-medium, ukusabalalisa, ukuhlukanisa noma ukuxuba okuphakathi. Njengama-valve okusabalalisa, ama-steam trap, nama-valve ebhola lezindlela ezintathu.
4. I-valve yokulawula: lungisa ingcindezi nokugeleza kwe-medium. Njenge-valve yokunciphisa ingcindezi, i-valve yokulawula, i-throttle valve.
5. I-valve yokuphepha: vimbela ukucindezela okuphakathi ocingweni ukuba lidlule inani elishiwo, futhi unikeze ukuvikelwa kokuphepha kokucindezela ngokweqile.
二. Imingcele eyisisekelo ye-i-valve
1. Ububanzi obujwayelekile bevalvu (DN).
2. Umfutho ojwayelekile wevalvu (PN).
3. Ukucindezela kanye nesilinganiso sokushisa kwe-valve: Uma izinga lokushisa lokusebenza kwe-valve lidlula izinga lokushisa lokubhekisela lokucindezela okubizwa ngokuthi, ukucindezela kwayo okuphezulu kokusebenza kufanele kuncishiswe ngokufanele.
4. Ukuguqulwa kweyunithi yokucindezela kwevalvu:
ILASI | 150 | 300 | 400 | 600 | 800 | 900 | 1500 | 2500 |
I-MPa | 1.62.0 | 2.54.05.0 | 6.3 | 10 | 13 | 15 | 25 | 42 |
5. Indlela esebenzayo ye-i-valve:
Amavalvu ezimboni asetshenziswa ku-petroleum, imboni yamakhemikhali, i-metallurgy, amandla kagesi, amandla enuzi nezinye izimboni. Imithombo yezindaba edluliswayo ihlanganisa amagesi (umoya, umusi, i-ammonia, igesi yamalahle, igesi ye-petroleum, igesi yemvelo, njll.); uketshezi (amanzi, i-ammonia ewuketshezi, uwoyela, ama-asidi, ama-alkali, njll.). Ezinye zazo zigqwala njengezibhamu ezingontuluntulu, kanti ezinye zinemisebe eyingozi kakhulu.
