Uxinzelelo lwevalve yokunceda luyenyuka kodwa alunyuki ukuya kuhlalutyo lwesizathu esiphezulu

Uxinzelelo lwevalve yokunceda luyenyuka kodwa alunyuki ukuya kuxinzelelo oluphezulu lokulungelelanisa. Esi siganeko siboniswa ngolu hlobo lulandelayo: nangona uxinzelelo olulawula isondo lesandla luqiniswe ngokupheleleyo, uxinzelelo alukwazi ukuqhubeka nokunyuka emva kokunyuka kuphela kwixabiso elithile, ngakumbi xa ukushisa kweoli kuphezulu. Ezona zizathu zilandelayo.

(1) Ngenxa yokuba undoqo wevalve ukhululekile kakhulu xa unomngxuma womzimba wevalve, uyahluzwa, ukrolwe, okanye unxitywe kakhulu emva kokusetyenziswa, inxalenye yokuqukuqela kwe-oyile ingena kwigumbi lasentwasahlobo ngomngxuma wokudambisa isivalo oyintloko ibuyela kwioyile. izibuko ngalo msantsa (ofana nevalve yohlobo lwe-Y, ivalve enamacandelo amabini); Kumacandelo amathathu eevalvu ezigxininisiweyo ezifana nodidi lwe-YF, ngenxa yokunxitywa komphezulu odibeneyo wokutyibilika we-spool yevalve engundoqo kunye nesigqubuthelo sevalvu ehambelana nomngxuma, umsantsa ohambelanayo mkhulu, kunye nokugeleza ukuya kwigumbi lasentwasahlobo ngokudambisa ivalve engundoqo. umngxuma ubuyela kwitanki yamafutha ngokusebenzisa umsantsa.

(2) Phakathi kwe-valve ye-pilot taper kunye nesihlalo ngenxa yeoli ye-hydraulic kumdaka, amanzi, umoya kunye nezinye iikhemikhali ezibangelwa ukugqoka kunye nokukrazula, ayikwazi ukuvalwa kakuhle, uxinzelelo alukwazi ukunyuka phezulu.

(3) Kukho umsantsa phakathi kwevalve yomqhubi wetaper kunye nesitulo sevalve. Okanye ayijikeleziswanga ibe yi-zigzag shape, ukwenzela ukuba ezimbini zingakwazi ukulingana kakuhle.

(4) Intambo ye-screw ye-handwheel elawula uxinzelelo okanye isikrufu sokulungelelanisa sityunyuziwe okanye sicinezelekile, ukwenzela ukuba i-handwheel elawula uxinzelelo ayinakuqiniswa kwindawo elinganiselweyo, kwaye i-valve yokuqhuba i-spring ayinakunyanzeliswa ngokupheleleyo kwindawo efanelekileyo, kwaye uxinzelelo alukwazi ukulungiswa ukuya phezulu.

(5) Imithombo yokulawula uxinzelelo ifakwe kumthombo othambileyo ngempazamo, okanye ukuqina kwentwasahlobo kuyancipha ngenxa yokukhathala, okanye uxinzelelo alukwazi ukulungiswa ukuya phezulu.

(6) Ngenxa yokugquma, iteyipha okanye ukungcola kwisangqa esingaphandle somngxuma wevalve engundoqo okanye undoqo wevalve, undoqo wevalve uxingekile kwindawo encinci yokuvuleka, kwaye inqaku licwangciswe kwimeko evuleke kancinane yokungagqitywanga. ukuvula. Ngeli xesha, nangona uxinzelelo lunokulungiswa kwixabiso elithile, alinakunyuswa.
