Ulwazi Olujwayelekile Lwevalvu II

1, I-valve yezindlela ezintathu I-valve yezindlela ezintathu inezimbobo ezintathu, ezilungele uhlelo lokulawula amapayipi oketshezi olunezikhombisi-ndlela ezintathu. Iningi lazo lisetshenziselwa ukulawulwa kwezinga lokushisa, ukulawulwa kwesilinganiso kanye nokulawulwa kwe-bypass of exchange exchange. Ekusetshenzisweni, kufanele sinake umehluko wokushisa oketshezi akufanele ube mkhulu kakhulu, ngokuvamile ube ngaphansi kuka-150 C, ngaphandle kwalokho i-valve yezindlela ezintathu izoba nokucindezeleka okukhulu, ngaphandle kwalokho i-valve yezindlela ezintathu izoba nokucindezeleka okukhulu futhi ibangele ukuguquguquka, okuholela. ekuvuzeni noma ekulimaleni endaweni yokuxhumana. I-valve yezindlela ezintathu ine-valve yokuhlangana enezinhlangothi ezintathu kanye ne-valve yokuphambukisa yezindlela ezintathu. I-valve yendlela-ntathu yokuhlangana iyisisetshenziswa esigeleza singene futhi siphume ezimbobeni zokungena ezimbili ngemva kokuxutshwa. I-valve yendlela-ntathu yokuphambukisa iyi-medium egeleza isuka endaweni eyodwa yokungena futhi ihlukaniswe yaba izingxenye ezimbili zokuphuma. 2. I-Cam Flexure Valve Cam flexure valve, eyaziwa nangokuthi i-eccentric rotary valve, inomgogodla oyisiyingi omise okwefeni, ephonswa ibe yinye ngengalo eguquguqukayo nomkhono futhi igxiliswe ku-shaft ejikelezayo. Ingalo ephambukayo ingaveza ukuchezuka ngaphansi kwesenzo sokucindezela, okwenza indawo eyindilinga ye-valve core ixhumane eduze nendandatho yesihlalo futhi ibe nokusebenza kahle kokuvala. Inezinzuzo zesisindo esikhanyayo, ivolumu encane, ukufakwa okulula, futhi ifanele ukulawulwa kokugeleza okuphakathi nge-viscosity ephezulu kanye nendaba emisiwe. 3. Ivalvu Yesihlalo Esisodwa Eqondile Kunesihlalo esisodwa kuphela kanye ne-spool emzimbeni we-valve yesihlalo esisodwa. Izinzuzo zayo ziyisakhiwo esilula nomphumela omuhle wokuvala, futhi kuwuhlobo lomzimba we-valve osetshenziswa kakhulu. Ububi bayo ukuthi inomthamo ongemuhle wokujikeleza kanye namandla amakhulu angalingani, angafaneleki ukucindezela okuphezulu okuhlukile kanye nezikhathi ezinkulu ze-caliber. 4. Ivalvu Yezihlalo Ezimbili Eqondile Kunezihlalo ezimbili nama-spools emzimbeni wevalvu enezihlalo ezimbili. Inzuzo ukuthi amandla asebenza kuma-spools angaphezulu naphansi oketshezi angakwazi ukuqedana, ngakho-ke i-valve enezihlalo ezimbili inomehluko omkhulu ovumelekile wokucindezela. Okubi ukuthi ama-spools aphezulu naphansi akufanele avaliwe ngesikhathi esifanayo, ngakho ukuvuza kukhulu. Ifanele imidiya ehlanzekile enomehluko omkhulu wokucindezela kuzo zombili iziphetho ze-valve kanye nesidingo esiphansi sokuvuza. Ayifanele izikhathi ze-viscosity ephezulu kanye ne-fiber-containing.
