Pneumatic manch kontwòl valv: Precision Flow Règleman nan sistèm endistriyèl

Yon valv kontwòl manch konpwesyonè se yon kalite espesyalize nan valv kontwòl ki fèt yo kontwole koule likid ak presizyon segondè nan pwosesis endistriyèl. Li itilize yon aksyon konpwesyon pou manipile yon manch rad fleksib, ki an vire kontwole koule nan likid, gaz, oswa slurries. Sa a se valv patikilyèman valè pou kapasite li nan okipe likid difisil ak bay egzat kontwòl koule nan aplikasyon pou divès kalite.

Estrikti ak konpozan

Valv kontwòl manch konpwesyon nan konsiste de plizyè konpozan kle yo. Nan nwayo li se yon manch rad fleksib, tipikman te fè nan kawotchou oswa lòt materyèl elastomerik, ki se loje nan yon kò valv. Se manch rad la ki fèt yo elaji oswa kontra an repons a presyon an aplike pa aksyon an konpwesyon.
Se aksyonè a konpwesyon ki konekte nan yon sistèm kontwòl ki founi lè konprese. Tou depan de konsepsyon an, actionneur a ka swa dirèk - aji oswa ranvèse - aji. Nan yon actuateur dirèk - aji, yon ogmantasyon nan presyon lè a lakòz manch rad la nan kontra, diminye zòn nan koule epi konsa mete restriksyon sou koule nan likid. Kontrèman, nan yon ranvèse - aji actuateur, yon ogmantasyon nan presyon lè a mennen nan ekspansyon nan manch rad la, ogmante zòn nan koule.
Se kò a valv anjeneral konstwi soti nan materyèl tankou fè jete, asye, oswa asye pur, bay sipò estriktirèl ak pwoteksyon pou eleman yo entèn yo. Li tou karakteristik pò Inlet ak priz pou likid la antre nan ak sòti valv la.

K ap travay prensip

Operasyon an nan yon valv kontwòl manch konpwesyonè ki baze sou prensip la nan varye zòn nan koule nan deformation nan manch rad la fleksib. Lè sistèm kontwòl la voye yon siyal nan aksyon an konpwesyon, lè konprese apwovizyone nan chanm lan actionneur. Sa a presyon lè aji sou yon dyafram oswa Piston nan actionneur a, génération yon fòs ki transmèt nan manch rad la.
Kòm manch rad la defòme (kontra oswa agrandi), kwa - zòn nan rejyonal ki disponib pou chanjman koule likid. Sa a, nan vire, transforms pousantaj la koule nan likid la pase nan valv la. Relasyon ki genyen ant presyon lè a aplike nan aksyonè a ak pousantaj la koule ki kapab lakòz se tipikman lineyè oswa yo ka ajiste yo swiv yon koule espesifik koule karakteristik, tankou pousantaj egal oswa rapid - ouvèti, tou depann de kondisyon ki nan aplikasyon an.
