Ma Vavulo Oyang'anira Masika ndi Kugwedezeka
Chaputala 1 - Kodi Valavu Yoyang'anira Masika ndi Chiyani?
Vavu yowunikira masika ndi valavu yomwe imatsimikizira kuyenda kwa njira imodzi ndikuletsa kuyenda kwa masika. Ili ndi malo olowera ndi otulutsira ndipo iyenera kuyikidwa pamalo oyenera kuti igwire ntchito bwino. M'mbali mwa mavavu owunikira masika ndi mavavu onse owunikira, pali muvi woloza mbali ya kayendedwe ka madzi. Vavu yowunikira yokhala ndi masika imatchedwa valavu yowunikira njira imodzi kapena valavu yowunikira njira imodzi. Cholinga cha valavu yowunikira masika ndikugwiritsa ntchito kasupe ndi kupanikizika komwe kumayikidwa pa diski kuti kuletse kubwerera kwa madzi kuti kutseke valavu.

Kuti valavu yoyezera igwire ntchito bwino, iyenera kukhala ndi mphamvu yosiyana, yochokera pa mphamvu yapamwamba kupita ku mphamvu yochepa. Kupanikizika kwakukulu kapena kusweka kwa mphamvu kumbali yolowera kumalola madzi kuyenda kudzera mu valavu ndikugonjetsa mphamvu ya kasupe mu valavu.

Kawirikawiri, valavu yowunikira ndi chipangizo chomwe chimalola mtundu uliwonse wa cholumikizira kuyenda mbali imodzi. Mawonekedwe a makina owunikira akhoza kukhala ozungulira, diski, pistoni kapena poppet, mutu wa bowa. Mavalavu owunikira masika amaletsa kuyenda mobwerera m'mbuyo ngati njira yotetezera mapampu, zida ndi makina pamene kupanikizika mu dongosolo kukuyamba kuchepa, kuchepa, kuyima kapena kubwerera m'mbuyo.

Chaputala 2 - Kodi valavu yoyesera swing ndi chiyani?
Ma valve oyesera ozungulira amalola kuyenda kwa njira imodzi ndikutseka yokha pamene kupsinjika kwa ming'alu kumachepa. Ndi mtundu wa valavu ya gulugufe yokhala ndi diski yophimba kutsegula kwa valavu. Puck imalumikizidwa ku hinge kotero kuti ikakhudzidwa ndi kuyenda kwa media, puck imatha kutseguka kapena kutsekedwa. Muvi womwe uli mbali ya thupi la valavu umasonyeza njira yomwe madzi amalowa ndi kutuluka mu valavu.

Kuchuluka kwa mphamvu ya madzi kumakankhira diski kapena chitseko kuti chitseguke, zomwe zimapangitsa kuti madziwo adutse. Pamene madziwo akuyenda molakwika, diski imatsekedwa chifukwa cha kukankhidwa kwa madziwo kapena cholumikiziracho.

Valavu yowunikira Swing

Ma valve oyesera ma swing safuna mphamvu yakunja. Kudutsa kwa madzi kapena zolumikizira mkati mwake sikulepheretsedwa ndi kupezeka kwawo. Amayikidwa mopingasa m'mapaipi, koma amatha kuyikidwa moyimirira malinga ngati madzi akuyenda mmwamba.

Chaputala 3 - Mitundu ya Ma Vavu Oyesera Ma Spring
Kuti valavu yoyezera yodzaza ndi kasupe igwire bwino ntchito, iyenera kukhala ndi kupanikizika kwapamwamba, kotchedwa kupsinjika kwa kuphulika, kuti ikhale yotseguka. Kuchuluka kwa kupsinjika kwa kuphulika komwe kumafunika kumadalira mtundu wa valavu, kapangidwe kake, mawonekedwe a kasupe ndi komwe ikuyendera mupaipi. Mafotokozedwe a kupsinjika kwa kuphulika ali mu mapaundi pa inchi imodzi (PSIG), mapaundi pa inchi imodzi (PSI), kapena bala, ndipo gawo la kupsinjika limafanana ndi 14.5 psi.

Pamene kuthamanga kwa mpweya m'mwamba kuli kotsika kuposa kuthamanga kwa mpweya, kuthamanga kwa mpweya kumbuyo kumakhala chinthu chofunikira ndipo madzi amayesa kutuluka kuchokera pamalo otulukira mpweya pa valavu kupita kumalo olowera mpweya. Izi zikachitika, valavu imatseka yokha ndipo madzi amasiya kutuluka.

Mtundu wa Valavu Yoyang'anira Masika
Valavu yowunikira chete ya Axial flow
Ndi valavu yowunikira kayendedwe ka axial, mbale ya valavu imagwiridwa ndi kasupe womwe umayika pakati pa mbale ya valavu kuti iyende bwino komanso kuti itsegule ndi kutseka nthawi yomweyo. Kasupe ndi diski zili pakati pa chitoliro, ndipo madziwo amayendayenda mozungulira diski. Izi ndizosiyana ndi ma valavu ozungulira kapena mitundu ina ya ma valavu otsegulira, omwe amakoka diski yonse kuchokera mumadzimadzi, ndikusiya chubu chotseguka kwathunthu.

Kapangidwe kapadera ka valavu yoyang'anira kayendedwe ka axial flow silent imapangitsa kuti ikhale yokwera mtengo kuposa mavalavu oyendera masika ndi mavalavu oyendera swing. Ngakhale kuti ndi okwera mtengo kwambiri, phindu la ndalama zomwe zagwiritsidwa ntchito limachokera ku nthawi yayitali ya moyo wawo, yomwe ingatenge zaka zoposa zitatu kuti isinthidwe.

Kapangidwe kapadera ka Axial Flow Quiet Check Valve kamakupatsani mwayi wowona pansipa komwe valavu imatseguka ndi komwe madzi amatuluka. Monga ma valve owunikira masika, ma valve owunikira ma axial amayamba kutseka pamene kuthamanga kwa mpweya kumatsika. Pamene kuthamanga kukuchepa pang'onopang'ono, valavu imatseka pang'onopang'ono.

Valavu yowunikira mpira wa masika
Ma valve oyesera kasupe wa mpira amagwiritsa ntchito mpira ngati mpando wotsekera pafupi ndi dzenje lolowera. Mpando wotsekerawo umachepetsedwa kuti utsogolere mpirawo kuti ulowemo ndikupanga chisindikizo chabwino. Pamene kupsinjika kwa ming'alu kuchokera ku madzi kukukulira kuposa kasupe amene akusunga mpirawo, mpirawo umasunthidwa,
