I-Valve Basic

A isivalwanaiyithuluzi lokulawula umugqa we-fluid. Umsebenzi wayo oyisisekelo ukuxhuma noma ukunqamula ukusakazwa kwendandatho yepayipi, shintsha indlela yokugeleza ye-medium, lungisa ingcindezi kanye nokugeleza okuphakathi nendawo, futhi uvikele ukusebenza okujwayelekile kwepayipi nemishini.

一.Ukuhlukaniswa kwama-valves

Ngokusetshenziswa kanye nokusebenza kungahlukaniswa:

1. I-Valve evaliwe Njengo: I-valve valve, i-valve ye-genem, i-valve yebhola, i-valve ye-butterfly, i-valve ye-diaphragm, i-valve ye-plug.

2. Bheka i-valve: Vimbela okuphakathi epayipini ukuthi ligeleze emuva.

3. I-Hassivetion Valve: Shintsha ukuqondiswa kokugeleza kokuphakathi, ukusabalalisa, ukuhlukanisa noma ukuxuba okuphakathi. Njengama-valves okusatshalaliswa, izicupho ze-Steam, kanye nama-valves ebhola amathathu.

4. Ukulawula i-Valve: lungisa ingcindezi nokugeleza okuphakathi. Njengokucindezela okunciphisa i-valve, ukulawula i-valve, i-throttle valve.

二. Amapharamitha ayisisekelo weisivalwana

2. Ingcindezi yokuqothuka ye-valve (PN).

I-3. Isilinganiso sokucindezela kanye nokushisa kwe-valve: lapho amazinga okushisa e-valve edlula okushisa kwereferensi yengcindezi yokuqothuka, ingcindezi yayo yokusebenza kufanele incishiswe ngokufanele.

5. I-audiable of theisivalwana:

Ama-valve wezimboni asetshenziswa ku-petroleum, imboni yamakhemikhali, metallurgy, amandla kagesi, amandla enuzi kanye nezinye izimboni. Abezindaba badlula ngokudlula kwamagesi (umoya, umusi, i-ammonia, igesi yamalahle, igesi kaphethiloli, igesi yemvelo, njll.); Ama-Liquid (amanzi, ama-ammonia awuketshezi, uwoyela, ama-acid, ama-alkalis, njll.). Ezinye zazo zihlanza njengezibhamu zomshini, kanti ezinye ziyi-radioactive kakhulu.
