Ma valve a Newsway Valve Company (NSW) amagwiritsidwa ntchito kwambiri m'mapaipi osiyanasiyana, amatha kukwaniritsa zofunikira izi valavu zapaipi

1. Dulani ndi kumasula sing'anga

Ichi ndiye ntchito yofunikira kwambiri ya valve. Kawirikawiri, valavu yokhala ndi njira yowongoka yoyenda imasankhidwa, ndipo kukana kwake kumakhala kochepa.

Ma valve otsekedwa pansi (Ma valve a Globe, ma valve plunger) sagwiritsidwa ntchito kawirikawiri chifukwa cha maulendo awo oyendayenda komanso kuthamanga kwambiri kuposa ma valve ena. Kumene kukana kuthamanga kwapamwamba kumaloledwa, valve yotsekedwa ingagwiritsidwe ntchito.

2. Ckuyendetsa kuyenda

Kawirikawiri, valve yomwe imakhala yosavuta kusintha kayendedwe kake imasankhidwa ngati kayendetsedwe ka kayendedwe kake. Vavu yotsekera pansi (monga avalavu ya globe) ndiyoyenera kutero chifukwa kukula kwake kwa mpando kumayenderana ndi kugunda kwa membala wotseka.

Ma valve ozungulira (Ma valve olumikizira, valavu butterfly, ma valve a mpira) ndi ma flex-body valves (pinch valves, diaphragm valves) angagwiritsidwenso ntchito poyendetsa throttling, koma nthawi zambiri amangogwira ntchito m'kati mwa ma valve ochepa.

Valve yachipata imagwiritsa ntchito chipata chopangidwa ndi diski kuti ipangitse kusuntha kolowera kumpando wozungulira wa valve. Ikhoza kuyendetsa bwino kayendedwe kokha pamene ili pafupi ndi malo otsekedwa, kotero nthawi zambiri sagwiritsidwa ntchito poyendetsa kayendedwe.

3. Kubwerera m'mbuyo ndi kusuntha

Malinga ndi zosowa za kubweza ndi shunting, valavu yamtunduwu imatha kukhala ndi njira zitatu kapena kupitilira apo. Ma valve olumikizira ndiMa valve 3 a mpirandizoyenera kuchita izi. Chifukwa chake, mavavu ambiri omwe amagwiritsidwa ntchito potembenuza ndi kugawa otaya amasankha imodzi mwa ma valve awa.

Koma nthawi zina, ma valve amtundu wina amatha kugwiritsidwanso ntchito potembenuza ndi kutsekeka malinga ngati ma valve awiri kapena kuposera akugwirizanitsidwa bwino.

4. Yapakatikati yokhala ndi tinthu tating'onoting'ono

Pakakhala ma particles oimitsidwa mkatikati, ndi bwino kugwiritsa ntchito valavu yokhala ndi zotsatira zopukuta pa kutsetsereka kwa membala wotseka pambali yosindikiza.

Ngati kusuntha kwa kumbuyo ndi kutsogolo kwa membala wotseka kumpando wa vavu kumakhala koyima, kumatha kukhala ndi tinthu tating'onoting'ono. Chifukwa chake, valavu iyi ndiyoyenera kutengera zoyambira zoyera pokhapokha ngati chinthu chosindikizira chimalola kuti tinthu tating'onoting'ono tilowe. Mavavu a mpira ndi mavavu a pulagi ali ndi mphamvu yopukuta pamwamba pa kusindikiza pa nthawi yotsegula ndi kutseka, kotero ndi yoyenera kugwiritsidwa ntchito pazofalitsa ndi particles zoimitsidwa.
