Eshabhu laseJinbin, ababiliamavalvu esango le-hydraulic wedgeseziqediwe ekukhiqizweni. Izisebenzi zenza ukuhlolwa kokugcina kuzo. Ngemva kwalokho, lawa ma-valve amabili esango azopakishwa futhi alungele ukuthunyelwa. (Jinbin Valve: abakhiqizi bama-valve esango)

I-valve yesango le-hydraulic wedge ithatha amandla e-hydraulic njengengqikithi. Izingxenye ezibalulekile zifaka phakathi ama-actuator e-hydraulic (ikakhulukazi amasilinda), amapuleti esango, izihlalo zamavalvu kanye neziqu zamavalvu. Lapho uwoyela we-hydraulic ungena egumbini likawoyela ohlangothini olulodwa lwe-actuator, ingcindezi kawoyela iguqulwa ibe yi-linear thrust noma i-draw, iqhube i-valve stem ukuthi ihambe iqonde phezulu, bese iqhubela isango ukuthi likhuphuke futhi lehle ngesakhiwo esiqondisa isihlalo sevalvu: lapho isango lehla ukuze linamathele eduze esihlalweni sevalvu, kwakheka uphawu lobuso ukuze kuvinjwe ukugeleza kwe-medium (isimo esivaliwe). Uwoyela we-hydraulic ufakwa ngendlela ephambene negumbi likawoyela ngakolunye uhlangothi lwe-actuator. Isango liyaphakama futhi linqamuke esihlalweni sevalvu. Indlela yokugeleza isesimweni esiqondile, ivumela i-medium ukuthi idlule ngaphandle kwesithiyo (esimweni esivulekile), ngaleyo ndlela kufezwe ukulawulwa kokuvula nokuvala kwe-medium yepayipi.

I-valve yesango le-hydraulic flange inezici ezilandelayo ezibalulekile:

1. Ukuvala okuthembekile: Isango kanye nesihlalo sevalvu kuxhumene nobuso ukuze kuvalwe. Ngemva kokuvala, ukuvuza kwe-medium kuphansi kakhulu, ikakhulukazi kufaneleka ezidingweni zokuvala ngaphansi kwezimo zokusebenza ezicindezela kakhulu.

2. Ukuzivumelanisa nezimo okunamandla kokucindezela okuphezulu: Idrayivu ye-hydraulic inganikeza amandla amakhulu okushayela umthwalo. Umzimba wevalvu wenziwe kakhulu ngezinto ze-alloy ezinamandla aphezulu futhi ungamelana nezingcindezi ezisukela kumashumi kuya kumakhulu e-MPa.

3. Ukuvula nokuvala okubushelelezi: Ukudluliselwa kwe-hydraulic kunesici sokubhafa, okugwema ukushaya okuqinile phakathi kwesango nesihlalo se-valve, futhi kwandisa impilo ye-valve.

4. Ukumelana nokugeleza okuphansi: Uma ivuliwe ngokugcwele, isango liyahoxa ngokuphelele emgudwini wokugeleza, kungashiyi sithiyo emgudwini wokugeleza. Ukumelana kwe-medium kuphansi kakhulu kunokwezinye izinhlobo zamavalvu njengezivali zokuma.

I-valve yesango le-hydraulic engu-16 intshi isetshenziswa kakhulu ezimweni zezimboni ezinomfutho ophezulu, ezinobubanzi obukhulu ezinezidingo eziphezulu zokuvala nokuqina kokusebenza, njengemipayipi kawoyela negesi enomfutho ophezulu ensimini ye-petrochemical (emelana nomfutho ophezulu futhi engavuzi). Amapayipi okudlulisa amanzi/okukhipha amanzi anobubanzi obukhulu kumaphrojekthi okugcina amanzi (anomswakama omuhle kanye nokuvulwa nokuvala okubushelelezi); Amapayipi omusi okushisa okuphezulu kanye nomfutho ophezulu wokukhiqizwa kwamandla okushisa (afanele izimo zokusebenza ezinzima); Amapayipi ohlelo lwe-hydraulic ezimbonini zezimayini nezensimbi (amelana nezimo ezinzima njengothuli nokudlidliza).
