I-Valve Basic

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:

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.
