Ivalvu yokusiza esetshenziswa umshayeli Ivalvu yokusiza yezimayini i-RSDC-LAN

Ama-valve okusiza umshayeli ayatholakala ekucushweni okuhlukahlukene. Ivalvu yokusiza umshayeli yesakhiwo esinezigaba ezintathu esijwayelekile, esakhiwe izingxenye ezimbili: ivalvu yokushayela kanye nevalve eyinhloko.

I-taper pilot valve, imbobo edambisayo (imbobo yokudonsa egxilile) ku-spool ye-valve eyinhloko kanye nentwasahlobo elawula ukucindezela ndawonye kwakha umshayeli we-half-bridge partial pressure negative control negative, onesibopho sokuhlinzeka ngengcindezi yomyalo wesiteji esikhulu ngemva kwe-valve yokushayela. ukulawulwa kwengcindezi ekamelweni eliphezulu le-spool ye-valve eyinhloko. I-spool eyinhloko iyisiqhathanisi se-loop yokulawula eyinhloko. Ubuso bokugcina obungaphezulu busebenza njengamandla omyalo we-spool eyinhloko, kuyilapho ubuso bokugcina obuphansi busebenza njengendawo yokulinganisa ingcindezi yeluphu eyinhloko futhi busebenza njengamandla empendulo. Amandla angumphumela angakwazi ukushayela i-spool, alungise usayizi wembobo echichimayo, futhi ekugcineni afeze injongo yokulawula nokulawula ukucindezela kwe-inlet pressure P1.

Uhlobo lwe-YF olunezigaba ezintathu zesakhiwo se-valve yokusiza umshayeli wendiza egxilile Umfanekiso 1-(- i-taper valve (i-valve yokushayela); 2 - Isihlalo sekhoni 3 - isembozo sevalvu; 4 - Umzimba we-valve; 5 - imbobo emanzi; 6 - i-valve eyinhloko; 7 - I-Main isihlalo se-8 - i-valve eyinhloko ye-9 - ukulawulwa kwengcindezi (i-valve yokushayela) i-spring 10 - ukulungisa i-handwheel;

Izinzuzo ze-hydraulic cartridge valve:

①Awukho umthelela ohlehlayo wesivinini esikhulu:

lokhu kujwayeleke kakhulu ukuphathwa yikhanda ezinhlelweni ezisebenza ngama-hydraulic ezinamandla kakhulu. Ngenxa yokuthi i-valve ye-cartridge iyisakhiwo se-valve ye-conical ehlangene, ivolumu yokulawula incane uma ushintsha, futhi awukho umqondo "wekhava enhle" we-valve yesilayidi, ngakho-ke ingashintshwa ngesivinini esikhulu. Ngokuthatha izinyathelo ezithile zezingxenye zengxenye yokuhlola nokujwayela ukulawulwa kwesimo soguquko phakathi nenqubo yokushintsha, umthelela ohlehlayo ungancishiswa kakhulu ngesikhathi sokushintsha.

② Ngokuthembeka kokushintsha okuphezulu:

i-valve ye-cone ejwayelekile inzima ukubangela isenzo esibi ngenxa yokungcola, ukulahlekelwa kwengcindezi encane, ukushisa okuncane, futhi i-spool inengxenye yomhlahlandlela ende, okungekho lula ukukhiqiza i-skew stuck phenomenon, ngakho-ke isenzo sinokwethenjelwa.

③Ngenxa yokuthi i-valve ye-cartridge logic imisiwe ekhaya naphesheya, kungakhathaliseki ukuthi iyindinganiso yamazwe ngamazwe ye-ISO7368, i-Germany DIN 24342 kanye ne-China (i-GB 2877 standard) ibeke usayizi wokufaka ojwayelekile emhlabeni, ongenza izingxenye zekhatriji zabakhiqizi abahlukene zishintshe, futhi akubandakanyi ukwakheka kwangaphakathi kwe-valve. Lokhu futhi kunikeza umsebenzi womklamo we-hydraulic valve ukuze ushiye indawo ebanzi yokuthuthukiswa.
