Amavalvu ovemvane ahlinzeka ngokulawula okungasindi futhi okunezindleko eziphansi phezu kokugeleza kwamanzi kumshini wokufafaza umlilo namasistimu wamapayipi
I-valve uvemvane ihlukanisa noma ilawule ukugeleza koketshezi ngamasistimu amapayipi.Nakuba zingasetshenziswa noketshezi, amagesi, ngisho neziqina eziqinile, amavalvu ovemvane okuvikela umlilo asebenza njengamavalvu alawulayo avula noma avale ukugeleza kwamanzi emapayipini anikeza isifafazi somlilo noma amasistimu amapayipi omoya.
I-valve uvemvane yokuvikela umlilo iqala, imise, noma icindezele ukugeleza kwamanzi ngokuzungezisa idiski yangaphakathi.Lapho i-disc iphendulwa ngokuhambisana nokugeleza, amanzi angadlula ngokukhululekile.Zungezisa i-disc ngamadigri angu-90, futhi ukuhamba kwamanzi kuhlelo lwamapayipi kuyama.Leli cwecwe elincanyana lingahlala endleleni yamanzi ngaso sonke isikhathi ngaphandle kokunciphisa kakhulu ukuhamba kwamanzi ngevalvu.
Ukujikeleza kwediski kulawulwa isondo lesandla.Isondo lesandla lizungezisa induku noma isiqu, esiphendulela i-disc futhi ngesikhathi esifanayo sizungezisa inkomba yendawo - ngokuvamile ucezu olunemibala egqamile oluphuma ku-valve - okubonisa opharetha ukuthi idiski ibheke ngakuphi.Le nkomba ivumela ukuqinisekiswa kokubuka nje ukuthi i-valve ivuliwe noma ivaliwe.
Inkomba yesikhundla idlala indima ebalulekile ekugcineni izinhlelo zokuvikela umlilo zisebenza.Amavalvu ovemvane asebenza njengamavalvu okulawula akwazi ukuvala amanzi ukuze ashise amasistimu wokufafaza noma ama-standpipe noma izingxenye zawo.Wonke amabhilidi angashiywa engenakuzivikela lapho i-valve yokulawula ishiywe ivaliwe ngokungenhloso.Inkomba yesikhundla isiza ochwepheshe bomlilo nabaphathi besikhungo ukuthi babone i-valve evaliwe futhi bayivule kabusha ngokushesha.
Amavalvu amaningi ovemvane okuvikela umlilo ahlanganisa namaswishi e-electronic tamper axhumana nephaneli yokulawula futhi athumele i-alamu lapho idiski yevalvu izungeza.Ngokuvamile, ahlanganisa amaswishi amabili e-tamper: eyodwa yokuxhuma iphaneli yokulawula umlilo kanye neyokuxhuma kudivayisi engumsizi, njengensimbi noma uphondo.
