Izingxenye zemishini yezimayini zobunjiniyela I-hydraulic valve cartridge balancing valve CBIG-LJN

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;

Ukuhlukaniswa komsebenzi

Lapho usebenza, ingcindezi yoketshezi isebenza endaweni yokulinganisa ingcindezi ye-spool eyinhloko kanye ne-spool yomshayeli ngesikhathi esisodwa. Lapho i-valve 1 yomshayeli ingavulwa, amafutha awagelezi ekamelweni le-valve, futhi ingcindezi esebenza ku-spool eyinhloko kuzo zombili izinkomba iyalingana, kodwa ngenxa yokuthi indawo yokucindezela ephumelelayo yokuphela okuphezulu inkulu kunendawo yokucindezela ephumelelayo. ekugcineni okuphansi, i-spool eyinhloko isendaweni engezansi ngaphansi kwesenzo samandla aphumela, futhi imbobo ye-valve ivaliwe. Lapho umfutho we-inlet ukhuphuka ngokwanele ukuvula i-valve yokushayela, uketshezi lugeleza ngembobo yokumanzisa ku-spool ye-valve eyinhloko kanye ne-valve yokushayela ibuyele ethangini. Ngenxa yomphumela wokudambisa wembobo yokudambisa, i-spool eyinhloko ingaphansi kwezikhombisi-ndlela ezingaphezulu neziphansi zokucindezela kwe-liquid ayilingani, i-spool eyinhloko ikhuphukela phezulu ngaphansi kwesenzo somehluko wengcindezi, ivula imbobo ye-valve, ibona ukuchichima. , futhi igcina ukuzinza okuyisisekelo kwengcindezi. Ukucindezela okuchichimayo kungalungiswa ngokulungisa intwasahlobo elawula ingcindezi ye-valve yokushayela.
