A: I-valve yezokuphepha iyisengezo esibalulekile sokuphepha ku-boiler. Umsebenzi wayo ukuthi: Lapho ingcindezi e-Steam Boiler inkulu kunenani elicacisiwe (okusho ingcindezi yokuthatha i-valve yokuphepha), i-valve yezokuphepha izovula ngokuzenzakalelayo i-valve ukukhipha umusi wokukhululeka kwengcindezi; Lapho ingcindezi e-boiler yehla inetha lokucindezela elidingekayo (ie), i-valve yezokuphepha ivalwa ngokuzenzakalelayo, ukuze i-boiler ingasetshenziswa ngokuphepha isikhathi esithile ngaphansi kwengcindezi yokusebenza ejwayelekile. Isikhathi eside, gwema ukuqhuma okubangelwa ukweqa ngokweqile kwe-boiler.
Inhloso yokufaka nokushintsha i-valve yezokuphepha ku-boiler ukudedela ingcindezi futhi ukhumbuze ama-boiler lapho ama-boiler ecindezelekile ngenxa yezici ezifana nokusetshenziswa okuphephile. Amanye ama-boilers awahlonyelwe nge-valve yomoya. Lapho amanzi engena isithando somlilo esibandayo ukukhuphula umlilo, i-valve yokuphepha isasusa umoya emzimbeni wesithando; iyageleza.
I-valve yezokuphepha iqukethe isihlalo se-valve, isisekelo se-valve kanye nedivayisi yokuqinisa. Indima ephephile ixhumana nesikhala se-Steam of the Boiler, kanti umnyombo we-valve ucindezelwa ngokuqinile esihlalweni se-valve ngamandla acindezelayo akhiwa yidivaysi ecindezelwe. Lapho amandla acindezelayo ukuthi i-valve core ingamelana inkulu kakhulu kune-thrust yomusi osemqoka we-valve, i-valve core tights esihlalweni se-valve, futhi i-valve yezokuphepha isesimweni esivaliwe; Lapho umfutho we-steam e-boiler ukhuphuka, amandla omvunzi osebenza ngokwanda okuyisisekelo kwe-valve, lapho amandla awo mkhulu kune-contepression core ingavuleka esihlalweni se-valve, i-valve yezokuphepha izovulwa, bese i-boiler izoyicindezela ngokushesha.
Ngenxa yokukhishwa kwe-Steam ku-boiler, umfutho we-boiler kuncishisiwe, bese kuthi ukushukunyiswa komusi okungamandla we-valve kungabhekwa, kanti kungaphansi kwamandla okucindezela angakwazi ukuthwala, futhi i-valve yezokuphepha ivalwa ngokuzenzakalelayo.
Ama-boilers anokuhwamuka okulinganiselwe okukhulu kune-0.5t / h noma amandla alinganiselwe ama-hormal amanga amakhulu kune noma alingana nama-350kw azohlonyiswa ngama-valves amabili okuphepha; Ama-boilers anokuhwamuka okulinganiselwe okungaphansi kwe-0.5t / h noma amandla alinganiselwe amangale ngaphansi kwama-350kw azohlonyiswa okungenani i-valve eyodwa yokuphepha. Ama-valves nama-valves okuphepha kufanele alinganiswe njalo futhi kufanele avalwe ngemuva kokulinganisa.
