Incazelo Yomkhiqizo
Ukuvula noma ukuvala i-valve stem kufushane, futhi kunesenzo esithembekile sokusika.Lolu hlobo lwe-valve lufanelekile ukusika noma ukulawula ukudonsa kwe-medium.
Esimeni esivulekile, akusekho ukuxhumana phakathi kwesihlalo se-valve kanye ne-disc seal, ngakho-ke kukhona ukugqokwa okuncane endaweni yokuvala.Njengoba isihlalo kanye nediski yamavalvu amaningi embulunga kulula ukulungisa noma ukushintsha izigxivizo ngaphandle kokukhipha yonke ivalvu epayipini, ifaneleka isikhathi lapho ivalvu nepayipi kushiselwa ndawonye.Lapho i-medium idlula kulolu hlobo lwe-valve, isiqondiso sokugeleza siyashintshwa, ngakho-ke ukumelana nokugeleza kwe-valve yembulunga kuphakeme kunokwamanye ama-valve.
Izici Zomkhiqizo
1. Isakhiwo se-valve yokumisa silula kunaleyo ye-valve yesango, futhi kulula kakhulu ukukhiqiza nokugcina.
2. Indawo yokuvala akulula ukuyigqoka futhi ikunwaye, futhi ukusebenza kokuvala kuhle.Akukho kushelela phakathi kwediski ye-valve nendawo yokuvala ye-valve yomzimba lapho uvula futhi uvala, ngakho-ke ukuguga nokuklwebheka akubucayi, futhi impilo yesevisi yinde.
3. I-stroke ye-valve disc incane lapho ivula futhi ivala, ngakho-ke ukuphakama kwe-valve yokumisa kuncane kune-valve yesango, kodwa ubude besakhiwo bude kune-valve yesango.
4. I-torque yokuvula nokuvala inkulu, ukuvula nokuvala kunzima, futhi isikhathi sokuvula nokuvala side.
5. Ukumelana nokugeleza kukhulu, ngoba isiteshi esiphakathi emzimbeni we-valve sihlukumeza, ukumelana nokugeleza kukhulu, futhi ukusetshenziswa kwamandla kukhulu.
6. Isiqondiso sokugeleza okumaphakathi: Uma ingcindezi ebizwa ngokuthi i-PN≤6.4MPA, ngokuvamile isebenzisa ukugeleza komfula, kanti okuphakathi kugeleza kuya phezulu kusuka phansi kwe-valve disc;lapho ingcindezi yobunjiniyela i-PN≥10MPA, ngokuvamile ithatha ukugeleza okubuyela emuva, futhi okuphakathi kugeleza kuye phansi kusuka phezulu kwediski ye-valve ukwandisa Umsebenzi wokuvala.Uma isetshenziswa, i-valve yokuvala iphakathi ingagelezela ohlangothini olulodwa kuphela.Isiqondiso sokugeleza asikwazi ukushintshwa.
