Izici zokugeleza zokulawulai-valveikakhulukazi izinhlobo ezine zezici zokugeleza ezifana nephesenti eliwumugqa wokuvula ngokushesha kanye ne-parabola. Lapho efakwe inqubo yokulawula langempela, ingcindezi umehluko wei-valveizoshintsha ngokushintsha kokugeleza, okungukuthi, ukulahlekelwa kwengcindezi yengxenye yamapayipi kuzoba kuncane lapho ukugeleza kukuncane, ingcindezi ehlukilei-valveizoba nkulu, futhi umehluko wengcindezi wei-valvekuzoba kuncane uma ukugeleza kukukhulu Lokhu kuhlukile ezicini zemvelo ze-i-valveisici esibizwa ngokuthi isici sokugeleza esisebenzayo sesici sokuqala esisheshayo se-valve yangaphakathi simise okwediski, sisetshenziselwa kakhulu ukuvula nokuvala isenzo.
Ukulawula ukuma kwe-valve spool surface
Izici zokulawula ukugeleza kwe-i-valvekunqunywa inhlanganisela izici flow of thei-valvekanye nenqubo iphampu yamapayipi, njll Ngokusho isilinganisoi-valveukulahlekelwa kwengcindezi entweni ngayinye yokulawula kanye nohlelo, ingxenye yokulahlekelwa kwengcindezi ye-valve ohlelweni lwento yokulawula ikhethwa kuthebula elilandelayo Izici zokugeleza zevalvu Ukulawula ukugeleza noma ukulawulwa kwezinga loketshezi ngaphansi kuka-40% Ukulawula ukugeleza noma ukulawulwa kwezinga le-liquid ezingaphezu kuka-40 % ukulawulwa kwengcindezi noma izinga lokushisa ngaphansi kuka-50% ukulawulwa kwengcindezi noma ukulawulwa kwezinga lokushisa okungaphezu kuka-50% I-Linear ngoba ukulahlekelwa kwengcindezi yepayipi kuhambisana nesikwele sokukhuphuka kwezinga lokugeleza, uma izici zomzimba we-valve ziyizinguquko ezilula zomugqa, ukucindezelwa okuhlukile kwe-valve kuyanda lapho ukugeleza kukuncane, ukugeleza kwe-valve kuzoba kukhulu kakhulu, umehluko we-valve we-valve uyancipha lapho ukugeleza kukhulu, futhi ukugeleza akukwazi ukulingana nokuvulwa kwe-valve Kuze kube manje, ukwengeza izici zepayipi kanye nepompo ukuze kuzuzwe ukulawulwa kokugeleza okuzimele kobukhulu bokugeleza futhi kuphela ngokulingana nokuvulwa kwe-valve kuyinjongo yokuklama izici zephesenti ezilinganayo.
Uhlelo lwamapayipi kanye nokulahlekelwa kwengcindezi
Isenzo se-valve yokulawula singakhethwa ngokuya ngenhlanganisela yedivayisi yokushayela kanye nomzimba we-valve.
Inhlanganisela yomzimba we-Drive kanye ne-valve kanye nesenzo se-valve (isibonelo se-valve yesihlalo esisodwa)
Isenzo sevalvu sihlanganisa isenzo esihle esibuyisela emuva isenzo sohlobo lwesenzo sohlobo lwesenzo izindlela ezi-3 zohlobo lwe-diaphragm kanye ne-cylinder yohlobo lwe-pneumatic drive isenzo esihle singokwanda kwesignali yokucindezela UKUTHI UVALE indlela yevalvu, eyaziwa nangokuthi AIR UKUZE UVALE isenzo esihlehlayo singokwenyuka kwesignali yengcindezi VULA indlela yevalvu, eyaziwa nangokuthi I-AIR ukuze uvule noma Isignali yokusebenza kagesi ingaguqulwa ibe isignali yomoya ngokusebenzisa indawo. Uma isignali yokusebenza imisiwe noma umthombo womoya uphazamisekile futhi amandla enqamukile, sicela ukhethe i-valve UKUZE UVALE noma uvule ngokucabangela ukuphepha kwenqubo..
Isibonelo, lapho ulawula inani le-asidi ngokusebenzisa i-i-valveenqubweni yokuxuba amanzi ne-asidi, kuphephile futhi kunengqondo ukuvala ukulawulwa kwe-asidii-valvelapho ulayini wesignali kagesi uphukile noma ipayipi lesignali yomoya livuza futhi umthombo womoya uyaphazamiseka futhi amandla anqanyuliwe. I-valve yesenzo esibuyela emuva kufanele isetshenziswe.
