Muva nje, indawo yokusebenzela yokukhiqiza yefekthri yethu ibe nomsebenzi onzima, ikhiqiza inani elikhuluama-valve okushisa emoyeni, ama-valve esango lommese, namavalvu esango lamanzi. Abasebenzi baseworkshop sebepakishe inqwaba yamavalvu okwehlisa umfutho futhi bazowakhipha maduze.

I-valve yokunciphisa ingcindeziiyimishini yokulawula uketshezi esetshenziswa kakhulu emkhakheni wezimboni, umsebenzi wayo oyinhloko uwukunciphisa uketshezi olunomfutho ophezulu ukuya ezingeni elidingekayo lokucindezela okuphansi. Isimiso sokusebenza sentengo ye-valve yokunciphisa ingcindezi sisekelwe kumgomo we-fluid statics, olawula izinga lokugeleza nokucindezela koketshezi ngokulungisa idivayisi edonsayo ngaphakathi komzimba we-valve. Lapho uketshezi olunomfutho ophezulu lungena ku-valve yefekthri, amandla e-kinetic oketshezi azophushela umgogodla we-valve phezulu, futhi isiphethu sizobhekana nokucindezela, okubangele umgogodla we-valve uye phansi. Lapho amandla phakathi kwe-valve core kanye ne-spring ifinyelela ekulinganeni, i-valve yokunciphisa ingcindezi isebenza ngokuzinza ngaphakathi kwebanga lokucindezela elimisiwe.

Izinzuzo zama-valve okwehlisa ingcindezi:

1.Ukuzinza okuphezulu

I-valve yokunciphisa ingcindezi ingagcina ngokuzinzile ububanzi bengcindezi ebekiwe, iqinisekise ukusebenza okuvamile kwesistimu, futhi igweme umonakalo nokungasebenzi kahle okubangelwa izinguquko zengcindezi.

2.Ukuphepha okuphezulu

Ngokulawula kahle ukucindezela, i-valve yokunciphisa ingcindezi yamanzi ingavimbela ukuphuka kwamapayipi noma ukulimala kwemishini okubangelwa ukucindezela okukhulu, ukuthuthukisa ukuphepha kwesistimu.

3.Ukonga amandla okuphezulu

Ama-valve okwehlisa ingcindezi asiza ukwehlisa ukusetshenziswa kwamandla kagesi, ukunciphisa ukumosheka kwamandla, futhi abaluleke kakhulu ekuvikelweni kwemvelo nokongiwa kwamandla.

4.Ububanzi besicelo esibanzi

Ama-valve okunciphisa ukucindezela asetshenziswa kakhulu ezimbonini ezihlukahlukene ezifana namakhemikhali e-petrochemicals, ugesi, imithi, ukudla, kanye nezinhlelo zokuhlinzeka ngamanzi asemadolobheni, nezinhlelo eziningi zokusebenza.

Njengesisetshenziswa esibalulekile sokulawula uketshezi, ama-valve anciphisa ingcindezi adlala indima ebalulekile ekukhiqizweni kwezimboni zesimanje ngenxa yezimo zawo ezizinzile, eziphephile nezonga amandla. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ikusasaama-valve okwehlisa umfuthoizohlakanipha futhi isebenze kahle, inikeze iziqinisekiso ezinokwethenjelwa zokukhiqizwa kwezimboni. Uma unezidingo zokuthenga, sicela usithinte ngezansi.
