Mfundo Yogwirira Ntchito ya Valavu ya Gulugufe ya Pneumatic

 A valavu ya gulugufe ya pneumaticndi valavu yozungulira kotala yomwe imagwiritsidwa ntchito kulamulira kapena kupatula kuyenda kwa madzi mu payipi. Ili ndi diski yozungulira (nthawi zambiri imatchedwa "diski") yoyikidwa pa tsinde, yomwe imazungulira mkati mwa thupi la valavu. "Pneumatic" imatanthauza njira yoyendetsera, yomwe imagwiritsa ntchito mpweya wopanikizika kuyendetsa valavu, zomwe zimathandiza kuyendetsa kutali kapena kulamulira kokha.

Valavu ya gulugufe ya pneumatic ingagawidwe m'magawo awiri ofunikira: choyatsira mpweya ndi valavu ya gulugufe.

· Thupi la valavu ya gulugufe: Lili ndi thupi la valavu, diski (diski), tsinde, ndi mpando. Disikiyo imazungulira tsinde kuti itsegule ndi kutseka valavu.

· Choyendetsa mpweya wa pneumatic: Chimagwiritsa ntchito mpweya wopanikizika ngati gwero lamagetsi, kuyendetsa pisitoni kapena vane kuti ipange kuyenda kolunjika kapena kozungulira.

 

Zigawo Zofunika

*Vavu ya Gulugufe:

- Thupi la Valve: Chipinda chomwe chimasunga diski ndikulumikizana ndi chitoliro.

- Disiki (disiki): Mbale yosalala kapena yokwezedwa pang'ono yomwe imalamulira kuyenda kwa madzi. Ikagwiridwa motsatira njira yoyendera madzi, valavu imatseguka; ikagwiridwa mopingasa, imatseka.

- Tsinde: Ndodo yolumikizidwa ku diski yomwe imatumiza mphamvu yozungulira kuchokera ku actuator.

- Zisindikizo ndi mipando: Onetsetsani kuti yatsekedwa bwino ndipo letsa kutuluka kwa madzi.

*Woyendetsa

- Choyatsira mpweya: Kawirikawiri chimakhala ngati pistoni kapena diaphragm, chimasintha kuthamanga kwa mpweya kukhala kayendedwe ka makina. Chikhoza kukhala chogwira ntchito kawiri (kuthamanga kwa mpweya potsegula ndi kutseka) kapena chogwira ntchito kamodzi (mpweya wopita mbali imodzi, kasupe wobwerera).

2. Mfundo Yogwirira Ntchito

Kugwira ntchito kwa valavu ya gulugufe wa pneumatic kwenikweni ndi njira yolumikizidwa ndi "mpweya wopanikizika".→kuyambitsa kwa actuator→Kuzungulira kwa ma disc kuti azitha kuyendetsa bwino." Mwachidule, mphamvu ya pneumatic (mpweya wopanikizika) imasinthidwa kukhala kayendedwe ka makina ozungulira kuti ikhazikitse diski.

 2.1. Njira Yogwirira Ntchito:

- Mpweya wopanikizika wochokera ku gwero lakunja (monga compressor kapena control system) umaperekedwa ku actuator ya pneumatic.

- Mu actuator yogwira ntchito kawiri, mpweya umalowa mu doko limodzi kuti uzungulire tsinde la valavu motsatira wotchi (mwachitsanzo, kutsegula valavu), ndikulowa mu doko lina kuti uzungulire motsatira wotchi. Izi zimapangitsa kuyenda kolunjika mu pistoni kapena diaphragm, komwe kumasinthidwa kukhala kuzungulira kwa madigiri 90 ndi makina okhazikika ndi pinion kapena Scotch-yoke.

- Mu actuator yogwira ntchito imodzi, mpweya umakankhira pisitoni motsutsana ndi kasupe kuti itsegule valavu, ndipo kutulutsa mpweya kumalola kasupe kuti atseke yokha (kapangidwe kotetezeka).

 2.2. Ntchito ya Valuvu:

- Pamene choyeretsera chizungulira tsinde la valavu, diski imazungulira mkati mwa thupi la valavu.

- Malo Otseguka: Disikiyi imayenderana ndi komwe madzi akuyenda, kuchepetsa kukana ndikulola kuti madzi ayende bwino kudzera mu payipi. - Malo otsekedwa: Disikiyi imazungulira madigiri 90, molunjika ku komwe madzi akuyenda, kutseka njira ndikutseka mpando.

- Malo apakati amatha kusuntha madzi, ngakhale ma valve a gulugufe ndi oyenera kwambiri pa ntchito yoyimitsa kuposa kulamulira bwino chifukwa cha makhalidwe awo osagwirizana ndi mzere.

 2.3. Kulamulira ndi Kuyankha:

- Choyatsira nthawi zambiri chimagwirizanitsidwa ndi valavu ya solenoid kapena choyimitsa kuti chiziwongolera molondola kudzera mu zizindikiro zamagetsi.

- Sensa ikhoza kupereka mayankho a malo a valavu kuti zitsimikizire kuti ikugwira ntchito modalirika m'makina odziyendetsa okha.
