Supapa de picior este compus\u0103 din corp de supap\u0103, disc, capac, buc\u0219\u0103, inel de etan\u0219are \u0219i alte p\u0103r\u021bi. Vede\u021bi apa de la sursa de ap\u0103 \u00een figura de mai jos. Sub presiunea fluidului, discul deschide apa. C\u00e2nd presiunea din conducta de evacuare este oprit\u0103, discul se \u00eenchide rapid. Lichidul nu se va turna \u00eenapoi \u00een sursa de ap\u0103. Joac\u0103 rolul de pompare nestingherit\u0103 \u0219i de economisire a apei \u0219i a pierderilor de energie.<\/p>\n

Supapa de picior sau supapa de jos, care este de fapt un fel de supap\u0103 de re\u021binere \u0219i joac\u0103 un rol \u00een prevenirea returului de ap\u0103.<\/p>\n

Supapa de picior poate fi \u00eemp\u0103r\u021bit\u0103 \u00een supap\u0103 de picior din plastic \u0219i supap\u0103 de picior din metal \u00een func\u021bie de material \u0219i poate fi, de asemenea, \u00eemp\u0103r\u021bit\u0103 \u00een supap\u0103 de picior obi\u0219nuit\u0103 \u0219i supap\u0103 de picior cu ap\u0103 de sp\u0103lare \u00een contra.<\/p>\n

Supapele de picior sunt utilizate \u00een principal \u00een echipamentele mecanice pentru tratarea n\u0103molului, cum ar fi pompele. De obicei, supapele de picior sunt instalate \u00een partea de jos a conductelor de aspira\u021bie subacvatice ale pompelor pentru a preveni refluxul de \u0219lam.<\/p>\n

Supapa de picior este echipat\u0103 cu mai multe orificii de admisie pe capacul supapei \u0219i plas\u0103 de ecran pentru a reduce fluxul de impurit\u0103\u021bi \u0219i probabilitatea de blocare a supapei de picior. De\u0219i supapa de picior este echipat\u0103 cu plas\u0103 de ecran anti-\u00eenfundare, supapa de jos este \u00een general potrivit\u0103 pentru cur\u0103\u021barea mediilor. Supapa de picior nu este potrivit\u0103 pentru medii cu v\u00e2scozitate \u0219i granularitate excesive.<\/p>\n
